TECHNICAL FIELD

The present disclosure relates to the field of ice racing equipment, in particular to a locking device for assembling and disassembling a skate.

BACKGROUND

Skating is a sport that uses skates to walk or race on the ice. In winter Olympic Games, there are also many kinds of skating events, such as short-track speed skating for racing, racing speed skating and figure skating for performance. Curling and ice hockey have also appeared on the field in recent years. At the same time, countries are gradually vigorously promoting people to participate in various ice sports.

In the existing ice sports, the fierce high-speed sliding and the abrasion of skates, have great influence in skating, especially in such sports as ice hockey and figure skating, where the blades are short and the longitudinal curvature is large. Whether the, skates can be in the best state is very important. Therefore, at the ice hockey game or figure skating scene, it is necessary to use the gap between the games to quickly sharpen the skates without taking off the protective gear and skates. The best solution is to ensure that the skating shoes with detachable skates are in the best sharpness state. However, the existing skate replacement mechanism is very laborious and cumbersome to operate and has great potential safety problems. For example, in curling and ice hockey, it is very difficult for athletes to remove skates with thick gloves since athletes wear thick protective gear. However, removing protective gear to disassemble skates in a short gap in the competition will have many unfavorable factors for the competition, which on the one hand, may cause the adjustment to be less than optimal when wearing protective gear again, and on the other hand, may waste a lot of time. In addition, the ice residue deposited between the skates and the cutter groove in the market skates will condense after long-term sliding, which makes it difficult to remove the skates. For users who wear gloves and other protective gear, and a weak group among ordinary consumers such as women, children and the elderly, the operation when the skates need to be replaced is also very unfriendly. In order to ensure that the detachable skates are not easy to fall off in intense sports, commercially available skating shoes with replaceable skates usually uses a strong torsion spring or a high-hardness spring, so that the locking part in the disassembly and assembly of the skates can be firmly clamped with the hook on the skates, so as to ensure that the locking part for fixing the skates will not come loose due to the impact of external forces after the skates are installed, but it is not easy for professional ice hockey players or ordinary consumers to resist the strong torsion of the strong torsion spring or the elastic force of the spring in the process of disassembling and assembling the skates. For professional racing athletes, the time of each competition is very precious for them, and too much time cannot be wasted on changing skates. Moreover, because the parts that keep elasticity, such as springs or torsion springs, are usually made of metal, it is hard to avoid ice slag remaining in the skate bracket during skating, which easily leads to corrosion of elastic parts made of metal. In addition, due to the cold nature of sports on ice and snow, in the low temperature and rusty environment, metal is more likely to break due to sudden external force extrusion, which is very dangerous for the fierce high-speed confrontation movement.

In addition, in the prior art, there is a way to fix the skates by folding wrenches similar to those in bicycle quick-release assemblies, that is, using a hook-shaped member that can hook the hooks on the skates, and using a wrench hinged on the skate bracket at the tail of the hook-shaped member, the hook-shaped member is pressed at the top to compress the spring in the turning process, and then the hooks of the skates are released, so as to achieve the effect of quick disassembly and assembly. It is found in experiments that this method of fixing skates is very easy to cause the wrench to be turned over after the external sharp object squeezes the bottom position of the wrench. Because the top pressing, part of this wrench is usually designed as an eccentric wheel, it is basically inevitable that it will be turned over after being touched, which will cause very dangerous safety hazards for players or consumers who participate in, high-speed skating.

Therefore, the existing locking mechanism for assembling and disassembling a skate needs to be, improved urgently.

The present disclosure will be further described with reference to the accompanying drawings and specific embodiments. The first embodiment of the locking device for assembling and disassembling a skate as shown in FIGS. 1 to 10 comprises: a skate bracket 10 connected to the sole, wherein the bottom of the skate bracket 10 is provided with a cutter groove 11 into which a skate 14 is inserted, one end of the cutter groove 11 is provided with a first clamping point 12 capable of clamping a first skate hook 141A, and one end of the cutter groove 11 far away from the first clamping point 12 is provided with a hook accommodating cavity 13 into which a second skate hook 141B is inserted; in this embodiment, the first clamping point 12 is integrally formed in the skate bracket 10 when the skate bracket 10 is injection, molded;

a clamping member 20, wherein the clamping member 20 is slidably provided in the hook accommodating cavity 13 and is capable of locking the second skate hook 141B in the hook accommodating cavity 13 or releasing the second skate hook 141B from the hook accommodating cavity 13, and a guide groove 23 is provided in the hook accommodating cavity 13 to enable the clamping member 20 to move in the hook accommodating cavity 13;

a driving member 30, wherein the driving member 30 is provided on the skate bracket 10 and located at one side of the hook accommodating cavity 13, and the driving member 30 is capable of driving the clamping member 20 to slide back and forth in the hook accommodating cavity 13, so that the second skate hook 141B is locked by or released from the clamping member 20; by rotating the driving member 30, the clamping member 20 is driven to release the second skate hook 141B when moving forward, and lock the second skate hook 141B when moving backward, so that it cannot fall off from the hook accommodating cavity 13;

a locking part 6, wherein the locking part 6 is provided on the driving mnember 30 and is capable of being used to cooperate with the driving member 30 to prevent the clamping member 20 from sliding back and forth in the hook accommodating cavity 13.

In addition, the clamping member 20 is further provided with a pushing part 8, and when the clamping member 20 releases the second skate hook 141B, the pushing part 8 is capable of synchronously pushing the second skate hook 141B out of the hook accommodating cavity 13, so that the skate 14 is disassembled faster, and the difficulty of disassembling the skate 14 in the cutter groove 11 due to the blockage of the ice slag will be prevented, which will affect the time for replacing the skate.

The clamping member 20 comprises: a locking hook 21, wherein the locking hook is movably hooked with the second skate hook 141B; a guide member 22, wherein the guide member is fixedly connected to the upper end of the locking hook 21; and a driving shaft 34, which is rotatable left and right on the skate bracket 10, wherein the driving member 30 is provided on the driving shaft 34.

As shown in FIG. 6 and FIG. 7, the guide member 22 in this embodiment is a long square block, the bottom of which is integrally formed with a locking hook 21 bent backward. The shape of the locking hook 21 matches the shape of the second skate hook 141B. In this embodiment, if the hook of the second skate hook 141B is bent forward, the locking hook 21 is bent backward. If the hook of the second skate hook 141B is bent backward, the locking hook 21 is bent forward. The bending direction of the locking hook 21 will also change according to the shape of the skates actually matched. One end of the guide member 22 on the locking hook 21 is inserted into the guide groove 23 and can move back and forth in the guide groove 23. The guide groove 23 can be provided at the front end of the guide member 22 or at the rear of the guide member 22. It should be noted that in this embodiment, when the guide groove 23 is provided at the rear of the guide member 22, the tail end of the guide groove 23 is an open water outlet 231, which is communicated with the cutter groove 11. At this time, the bottom surface of the inner cavity of the guide groove 23 is a slope surface with a high front end and a low back end, so that the ice slag and water entering the hook accommodating cavity 13 can be better removed, so as to prevent the ice slag and water from freezing in the guide groove 23 and affect the activities of the guide member 22. When the guide groove 23 is provided at the front end of the guide member 22, there is no need to provide a water outlet and a slope surface with a high front end and a low back end. In this embodiment, the skate 14 is first inserted into the cutter groove 11, in which the first skate hook 141A is aligned with the first clamping point 12 for clamping, and the second skate hook 141B is turned over and inserted into the hook accommodating cavity 13. By rotating the driving shaft 34, the driving member 30 drives the guide member 22 with the locking hook 21 to move back and forth in the hook accommodating cavity 13. During, the moving process, the locking hook 21 is hooked with or released from the second skate hook 141B, so that the skate 14 is locked in the cutter groove 11 or released from the cutter groove 11.

FIG. 6 to FIG. 10 show the embodiment of the driving member 30. The driving member 30 comprises a rack 33 fixedly provided on the guide member 22; and a gear A35 fixedly provided on the driving shaft 34 and coaxial with the driving shaft 34. The gear A35 is meshed with the rack 33. The rack 33 is fixedly provided on the bottom surface of the guide member 22. In addition, one end of the driving shaft 34 passes through the side wall of the skate bracket 10. A screwing device 4 is provided at the end extending out of the outer side wall of the skate bracket 10. The screwing device 4 can be turned over and opened to facilitate the rotation of the driving shaft 34.

FIG. 1, FIG. 7 to FIG. 10 show the embodiment of the screwing device 4. The screwing device 4 comprises a folding locking wrench 41 hinged at the end of the driving shaft 34, the folding locking wrench 41 is capable of pulling the driving shaft 34 to axially displace when being turned over and opened, and the driving shaft 34 in the inner cavity of the skate bracket 10 is provided with a reset spring 5 capable of driving the driving shaft 34 to be reset after the folding locking wrench 41 is turned over to be parallel to the side wall of the skate bracket 10. In this embodiment, one end of the reset spring 5 is top pressed against the side wall of the inner cavity of the skate bracket 10, and the other end thereof is top pressed against the gear A35 (the driving member 30). In this embodiment, the hinging manner of the folding locking wrench 41 can be implemented with reference to the state shown in FIG. 1 and FIGS. 7 to 10. The folding locking wrench 41 is a long strip-shaped flip sheet with a rectangular notch at its bottom. The driving shaft 34 is hinged in the rectangular notch, and the position should be close to the middle of the flip sheet in the rectangular notch, so that when the folding locking wrench 41 is turned over and opened, the driving shaft 34 can be pulled to move axially toward the side wall surface of the skate bracket 10 where the folding locking wrench 41 is located (refer to FIG. 7 and FIG. 9). At this time, the return spring 5 is compressed, and the return spring 5 is released when the folding locking wrench 41 is turned over to be attached to the side wall and parallel to the outer wall surface of the skate bracket 10. The driving shaft 34 can be axially displaced away from the folding locking wrench 41. The side wall of the folding locking wrench 41 is attached to the side wall of the skate bracket 310 (refer to FIG. 1, FIG. 8 and FIG. 10), and the attached state is maintained, so that the folding locking wrench 41 of the skating shoes is prevented from being touched and hit during sliding. As can be seen from FIG. 1, FIG. 7 to FIG. 10, in this embodiment, the side wall of the skate bracket 10 where the folding locking wrench 41 is located is provided with an accommodating groove 411, which can accommodate the folding locking wrench 41 in the closed state. The diameter width of the accommodating groove 411 at the position where the driving shaft 34 passes through is larger than the width of the folding locking wrench 41, while the length, width and height of the accommodating groove 411 above the driving shaft 34 are basically the same as those of the folding locking wrench 41, and are just slightly larger than the length, width and height of the folding locking wrench 41 by 1 MM, so that the folding locking wrench 41 can be further locked to prevent accidental rotation. In actual use, compared with an eccentric wheel-shaped flip folding wrench used in bicycles, when the folding locking wrench 41 is turned over to be parallel to the side wall of the skate bracket 10, the contact surface of the screwing device 4 and the skate bracket 10 can be completely attached to the side wall of the skate bracket 10, reducing the risk that the folding locking wrench 41 is easily turned over by mistake due to the impact of external force, and increasing the safety of the, locking device for assembling and disassembling a skate.

As shown in FIG. 8 to FIG. 10, in this embodiment, the locking part 6 comprises a clamping groove 60 which is provided on the sidewall of the inner cavity of the skate bracket 10. The clamping groove 60 can clamp the teeth of the gear A35. When the driving shaft 34 is turned over to be in the closed state by the folding locking wrench 41 (refer to FIG. 1, FIG. 8 and FIG. 10), the return spring 5 is released, so that the driving shaft 34 drives the gear A35 to move away from the folding locking wrench 41. At this time, the clamping groove 60 just catches the teeth of the shifted gear A35, thus limiting the rotation of the gear A35. As can be seen from FIGS. 9 and 10, in this embodiment, the width of the gear A35 is greater than the displacement distance. Therefore, at this time, after the locking hook 21 and the second skate hook 141B are hooked, the teeth of the gear A35 will not be separated from the rack 33 by the left-right displacement of the gear A35. That is, when the gear A35 is displaced into the clamping groove 60, the teeth at the bottom of the gear A35 are clamped into the clamping groove 60 and the teeth of the rack 33 at the same time. Finally, the folding locking wrench 41 is accommodated in the accommodating groove 411 so that it cannot rotate, so as to achieve the state of completely locking the skate 14. On the contrary, the locking hook 21 is removed from the second skate hook 141B to release and unlock the skate 14. In addition, in repeated experiments and feedback from users, it is found that after a long time of skating, when it is necessary to change the skate to sharpen the skate or replace the skate, the ice residue remaining in the cutter groove 11 will be condensed between the skate 14 and the cutter groove 11, which sometimes makes it difficult to remove the skate by hand, especially when wearing gloves and other protective gear. Therefore, when the skate 14 is unlocked in this embodiment, the pushing, part 8 on the clamping member 20 can push the second skate hook 141B out of the hook accommodating cavity 13 synchronously while unlocking the second skate hook 141B, thus further realizing the effect of rapidly disassembling the skate. Specifically, as shown in FIG. 6, the pushing part 8 comprises a top pressing member 81 which is fixed at the bottom of the guide member 22 and extends downwards. The front bottom of the top pressing member 81 is provided with a chamfer (in this embodiment, the inverted arc angle is taken as an example), and the chamfer is used to squeeze the rear end of the top of the second skate hook 14IB during the synchronous movement of the top pressing member 81 along with the forward movement of the guide member 22, so that the second skate hook 141B is forced to move downward. At this time, since the first skate hook 141A at one end of the skate 14 is still clamped at the first clamping point 12, the skate 14 squeezes the back end of the top of the second skate hook 141B by the top pressing member 81, and the skate will be turned over downward with the first clamping point 12 as the axis (refer to FIG. 6 and FIG. 7). After the back end of the skate 14 is pushed out of the cutter groove 11, it can be easily removed. With this design, the skate 14 will be disassembled faster, preventing the skate 14 from being difficult to be disassembled due to the blockage of ice slag in the cutter groove 11, which not only greatly shortens the time for replacing the skate. but also can be used more friendly for users who wear gloves and other protective devices or users with less strength.

FIG. 11 to FIG. 16 show a second embodiment of a locking device for assembling and disassembling a skate of the present disclosure. It can be clearly seen from the figure that this embodiment is basically the same as the first embodiment, except that the fosrmation of the guide member 22 is different from the implementation of the driving member 30 and the locking part 6. In this embodiment, a strip-shaped groove 31 penetrates through the side wall of the guide member 22 from the left to the right, the driving shaft 34 is capable of passing through the strip-shaped groove 31, and the driving member 30 comprises a rack 33 fixedly provided on the guide member 22. The rack 33 is located on a side wall surface of the bottom plane of the strip-shaped groove 31. A gear A35 is fixedly provided on the driving shaft 34. The gear A35 is coaxial with the driving shaft 34 and can be meshed with the rack 33. In this embodiment, both ends of the driving shaft 34 are rotatably provided on the left and right side wall surfaces of the skate bracket 10. After the second skate hook 141B on the top of the skate 14 is inserted into the hook accommodating cavity 13, the driving shaft 34 is, rotated, and the gear A35 will rotate synchronously. Because the gear A35 is meshed with the rack 33, the rack 33 will be driven to move when the gear A35 rotates, thus causing a backward displacement in the guide groove 23. At the same time, the guide member 22 drives the locking hook 21 to move backward in the hook accommodating cavity 13. In this way, the hook tongue of the locking hook 21 will move towards the direction of the second skate hook 141B, until the two hooks will hold each other after the hook tongue of the second skate hook 141B is hooked. At this time, the locking of the skate 14 is completed. When unlocking, the driving shaft 34 can be rotated counterclockwise by the folding locking wrench 41, so that the skate 14 can be unlocked and released. The locking part 6 comprises locking teeth 32 arranged in sequence on the inner ring wall surface of the strip-shaped groove 31, each tooth surface of the locking teeth 32 at the top is consistent with each tooth surface of the rack 33, and the gear A 35 is capable of being clamped with the locking teeth 32 extending into the strip-shaped groove 31. After the folding locking wrench 41 is turned over horizontally (the “horizontal turning over” of the folding locking wrench 41 in this embodiment uses the angle shown in FIGS. 12 and 14 as an example, that is, the open state of the folding locking wrench 41) Due to the displacement of the driving shaft 34, the gear A35 on the driving shaft 34 will move out of the strip-shaped groove 31 at the same time, and then is meshed with the rack 33. The folding locking wrench 41 is rotated to unlock, install and fix the skate. When the folding locking wrench 41 is turned over to the vertical state (the “vertical” of the folding locking wrench 41 in this embodiment uses the angle shown in FIGS. 11, 15 to 16 as an example, that is, the closed state of the folding locking wrench 41), the return spring 5 (one end of the return spring 5 in this embodiment is top pressed against the side wall of the inner cavity of the skate bracket 10, and the other end thereof is top pressed against the gear A35 (the driving member 30) fixed on the driving shaft 34) will make the gear A35 re-enter the strip-shaped groove 31 with the locking teeth 32. As the upper and lower tooth surfaces of the gear A35 are meshed with the locking teeth 32 at the upper and lower positions in the strip-shaped groove 31, respectively, the gear A35 will be locked and cannot rotate at the present stage. Similarly, the guide member 22 will not be able to displace back and forth in the guide groove 23, which effectively ensures that the hook tongue of the locking hook 21 and the hook tongue of the second skate hook 141B will not be separated from each other, and ensures the safety of athletes wearing skating shoes in fierce high-speed sliding. In this embodiment, no matter whether the folding locking wrench 41 is turned over or the gear A35 is rotated by the folding locking wrench 41 to drive the locking hook 21 to move back and forth, the disassembly and assembly of the skate can be realized without too much force, and the disassembly and assembly of the skate can be completed more quickly, which greatly saves time.

FIG. 17 to FIG. 23 show a third embodiment of the locking device for assembling and disassembling a skate of the present disclosure. It can be clearly seen from the figure that this embodiment is basically the same as the first embodiment, except that the formation of the guide member 22 is different from the implementation of the driving member 30 and the locking part 6. A strip-shaped groove 31 penetrates through the side wall of the guide member 22 from left to right, the driving shaft 34 passes through the strip-shaped groove 31, and a U-shaped groove 36 is fixedly provided on one side of the guide member 22 adjacent to the folding locking wrench 41. A central notch 361 of the U-shaped groove 36 is communicated with the strip-shaped groove 31. The driving shaft 34 on the skate bracket 10 passes through the central notch 361 of the U-shaped groove 36 while passing through the strip-shaped groove 31. A swing rod 37 is provided on the driving shaft 34, and the swing rod 37 is located at the central notch 361 of the U-shaped groove 36. When the folding locking wrench 41 drives the driving shaft 34 to rotate counterclockwise or clockwise, the swing rod 37 swings with the driving shaft 34 as the axis, squeezing the left and right inner walls of the central notch 361, forcing the U-shaped groove 36 to drive the guide member 22 to move back and forth along the guide groove 23, and completing the hooking or separating of the locking hook 21 and the second skate hook 141B. However, the locking part 6 in this embodiment can be the same as the locking part 6 in the previous embodiment. Alternatively, a gear B is provided, which is coaxial with the driving shaft 34 and fixed on the driving shaft 34. Locking teeth 32 are arranged in sequence on the inner ring wall surface of the strip-shaped groove 31. The gear B and the locking teeth 32 are clamped with each other when the driving shaft 34 is displaced into the strip-shaped groove 31. The gear B is provided on the side of the swing rod 37 and the gear A35 adjacent to the guide member 22, and is fixedly sleeved on the driving shaft 34 and coaxial with the driving shaft 34. When the folding locking wrench 41 is turned over to the same vertical state as the side wall of the skate bracket 10 (the “vertical state” of the folding locking wrench 41 in this embodiment uses the angle shown in FIGS. 18 to 23 as an example, that is, the closed state of the folding locking wrench 41), the swing rod 37, the gear A35 and the gear B move along the axial direction of the driving shaft 34 with the driving shaft 34. At this time, the gear A35 and the gear B enter the strip-shaped groove 31 and are clamped with the locking teeth 32 to lock the guide member 22, so that it cannot move back and forth in the guide groove 23. On the contrary, when the folding locking wrench 41 is turned over to be vertical or horizontal to the side wall of the skate bracket 10 (the “horizontal state” of the folding locking wrench 41 in this embodiment uses the angle shown in FIGS. 18 to 23 as an example, that is, the open state of the folding locking wrench 41), the guide member 22 can be unlocked, and the hook 21 can be separated from the second skate hook 141B hooked therewith, so as to achieve the purpose of disassembling the skate. Of course, it should be noted that the shape of the U-shaped groove 36 in this embodiment is not limited to U-shape, but also can be provided as an oval shape with a long top side and a long bottom side. In addition, it should also be noted that FIGS. 20 to 23 also show another embodiment of the locking part 6 based on this embodiment. A polygonal block 61 is fixedly sleeved at one end of the driving shaft 34 away from the folding locking wrench 41, and the polygonal block 61 is coaxially provided with the driving shaft 34. Correspondingly, the inner wall of the skate bracket 10 is also provided with a polygonal groove 62, which can accommodate the polygonal block 61. When the folding locking wrench 41 is turned over to be in the same vertical state as the side wall of the skate bracket 10, the driving shaft 34 moves in the direction of the polygonal groove 62 along the axial direction. At this time, the polygonal block 61 is inserted into the polygonal groove 62, and the swing rod 37 and the driving shaft 34 are locked so that they cannot be reversed, achieving the effect that the locking hook 21 and the second skate hook 141B hooked therewith are locked and cannot be separated from each other. On the contrary, when the folding locking wrench 41 is turned over to be vertical to the side wall of the skate bracket 10, the guide member 22 can be unlocked, so that the locking hook 21 can be separated from its hooked second skate hook 141B, and the purpose of detaching the skate 14 can be achieved. Of course, another embodiment of the locking part 6 in this embodiment can also be implemented in combination with the first embodiment of the present disclosure, that is, the polygonal groove 62 provided on the inner wall of the skate bracket 10 is used to replace the clamping groove 60 in the first embodiment, and the polygonal block 61 is matched to replace the locking part 6 in the first embodiment.

n the embodiment of the present disclosure, a return spring 211 can also be provided at one end of the locking hook 21, one end of the return spring 211 is top pressed and fixed on the side wall end of the locking hook 21, and the other end thereof is top pressed and fixed on the inner wall of the hook accommodating cavity 13. When the locking hook 21 and the second skate hook 141B arc released, the return spring 211 can automatically rebound the locking hook 21, reducing the manual screwing time.

In addition, as shown in FIG. 2 to FIG. 5 and FIG. 11, FIG. 12 and FIG. 14, in the above embodiment, a fixing part 7 is further provided between the folding locking wrench 41 and the outer side wall of the skate bracket 10, and the fixing part 7 is capable of fixing the folding locking wrench 41 on the outer side wall of the skate bracket 10 after the folding locking wrench is turned over vertically. In one embodiment, the fixing part 7 comprises a fastener 71 provided on the outer side wall of the folding locking wrench 41, and a through-hole fastener 70 provided on the outer side wall of the skate bracket 10 into which the fastener 71 is inserted and clamped together. The fastener 71 comprises: a fastening groove 72 provided at the tail end of the folding locking wrench 41 and provided with an opening; a pressing block 73, one end of which extends out of the opening of the fastening groove 72, and the other end of which is capable of moving back and forth in the fastening groove 72; a hook 74, which extends outward from the pressing block 73 towards the wall surface of the outer side wall of the skate bracket 10 and is capable of being inserted into the through-hole fastener 70 to be hooked and fixed; a pressing spring 75, which is provided between the pressing block 73 and the wall surface of the fastening groove 72, and is capable of keeping the pressing block 73 extending outward. In this embodiment, after the hook 74 extends into the through-hole fastener 70, the hook is hooked on the inner side wall surface of the skate bracket 10. Because the pressing spring 75 will top press the pressing block 73 toward the opening direction of the fastening groove 72, and the hook body of the fastener will also face the opening direction of the fastening groove 72, at this time, the fastener will be firmly hooked in the through-hole fastener 70, thus avoiding the hidden danger that the folding locking wrench 41 will be turned over or opened after accidental collision during sliding. Alternatively, another embodiment of the fixing part 7 comprises magnets which are respectively provided on the, outer side walls of the folding locking wrench 41 and the skate bracket 10 and can be mutually attracted together. By the mutual attraction of the magnets, the effect, of preventing, the folding locking wrench 41 from being turned over or opened after accidental collision during sliding can also be achieved. The state after the folding locking wrench 41 is vertically turned over in the above embodiment is the overlapping state that the side wall of the folding locking wrench 41 is adhered to the wall surface of the accommodating groove 411 on the outer side wall surface of the skate support 10 (refer to the attached drawing for details).

It should be noted that the above embodiment is not the only way, and the combination of the locking part 6 and the driving member 30 can be combined according to actual use.
