Description

CROSS-REFERENCE TO THE RELATED APPLICATIONS

This application is a continuation application of International Application No. PCT/CN2025/081958, filed on March 11, 2025, which is based upon and claims priority to Chinese Patent Application No. 202411750414.6, filed on November 30, 2024, the entire contents of which are incorporated herein by reference.

TECHNICAL FIELD

The present disclosure relates to the field of optical instruments, and in particular to an external adjustment base for a sight and the sight.

BACKGROUND

As an optical device designed to assist a user in accurately targeting an object, a sight is greatly affected by the environment during use. Therefore, it is necessary to reasonably adjust the position of the reticle during zeroing to align the reticle lines with the bullet impact points.

In a conventionally used sight, the position of the reticle inside the sight body is usually adjusted through an internal adjustment mechanism. For example, as disclosed in US20210325147A1, entitled Adjustment Apparatus of Reticle Device of Telescopic Sight, the position of the reticle is altered by a ballistic compensation knob located directly above and a windage compensation knob located on any side of the sight body to compensate for the influence of environmental factors such as gravity and wind. However, the limited internal space of the sight body leads to a small adjustment stroke of the compensation knobs, which fails to meet the requirement for large-deviation adjustment. To increase the adjustment stroke, the size of the sight body needs to be enlarged, which will result in excessively large volume and weight of the sight body and compromise the stability of the reticle.

To meet the requirement for large-deviation adjustment, the prior art provides an external adjustment mechanism, which is disposed on the exterior of the sight body to overcome the drawback of a small adjustment stroke. For example, as disclosed in US20110041378A1, entitled Method and Apparatus for Adjustably Supporting Component in Optical Sight, the user is allowed to move the sight body through an external adjustment mechanism to align the reticle lines of the optical system inside the sight body with the bullet impact points. Although the disclosure can increase the adjustable stroke of the sight to some extent, the ballistic adjustment handwheel disposed between the sight body and the base takes up a certain amount of vertical space and inconveniences the user during adjustment.

FIG. 1 is an exploded view of a sight according to an embodiment of the present disclosure. The sight includes an external adjustment base and sight body 50.

FIG. 2 is a schematic structural view of an external adjustment base for a sight according to an embodiment of the present disclosure. As shown in FIG. 2, the external adjustment base for a sight includes base body 10, first adjustment assembly 20, and second adjustment assembly 30. The first adjustment assembly 20 and the second adjustment assembly 30 are disposed on the base body 10 along first direction X. A top of the base body 10 is configured to mount the sight body 50 of the sight.

The first adjustment assembly 20 includes first adjustment rod 21 disposed along second direction Y, and the second adjustment assembly 30 includes second adjustment rod 31 disposed along the second direction Y. The second direction Y intersects with the first direction X. For example, the second direction Y may be perpendicular to the first direction X.

One end of the first adjustment rod 21 and one end of the second adjustment rod 31 are located on a lateral side of the base body 10, and the first adjustment rod 21 and the second adjustment rod 31 are configured to be connected to the sight body 50. The first adjustment assembly 20 is configured to make the sight body 50 rotate around the second adjustment rod 31 with the rotation of the first adjustment rod 21. The second adjustment assembly 30 is configured to make the sight body 50 move along the second adjustment rod 31 with the rotation of the second adjustment rod 31.

By disposing the first adjustment assembly 20 and the second adjustment assembly 30 on the base body 10 along the first direction X, the first adjustment assembly 20 and the second adjustment assembly 30 are configured to adjust the sight body 50. Since both the first adjustment assembly 20 and the second adjustment assembly 30 are located outside the sight body 50, the adjustment stroke is not limited by the size of the sight body 50, facilitating the large-deviation adjustment of the sight body 50. The first adjustment assembly 20 includes the first adjustment rod 21 disposed along the second direction Y, and the second adjustment assembly 30 includes the second adjustment rod 31 disposed along the second direction Y. The first adjustment rod 21 and the second adjustment rod 31 are connected to the sight body. Since one end of the first adjustment rod 21 and one end of the second adjustment rod 31 are both located on the lateral side of the base body 10, the first adjustment rod 21 and the second adjustment rod 31 can be operated from the lateral side of the base body 10. The first adjustment assembly 20 is configured to make the sight body 50 rotate around the second adjustment rod 31 with the rotation of the first adjustment rod 21, and the second adjustment assembly 30 is configured to make the sight body 50 move along the second adjustment rod 31 with the rotation of the second adjustment rod 31. Thus, a user can rotate the first adjustment rod 21 and the second adjustment rod 31 from the lateral side of the base body 10 to adjust the pitch angle and offset of the sight body 50, thereby improving the aiming accuracy. The operation is performed directly from the lateral side of the base body 10 during use, thereby enabling easy operation.

As shown in FIG. 2, one side of the base body 10 may be provided with pressure member 41, and the pressure member 41 is connected to the base body 10 through screw rod 42. The screw rod 42 may extend through the base body 10 along the second direction Y. Washer 43 and fastening nut 44 may be sleeved outside the screw rod 42, and both the washer 43 and the fastening nut 44 are located on a side of the pressure member 41 away from the base body 10. The pressure member 41 and the base body 10 can be clamped onto a guide rail of an apparatus for mounting the sight, and the pressure member 41 is pressed tightly by screwing the fastening nut 44 to clamp the sight firmly.

FIG. 3 is a partial exploded view of a first adjustment assembly according to an embodiment of the present disclosure. As shown in FIG. 3, the first adjustment rod 21 includes first rod body 211 and first rotation portion 212, and the first rotation portion 212 is connected to one end of the first rod body 211. As shown in FIG. 1, the second adjustment rod 31 includes second rod body 311 and second rotation portion 312, and the second rotation portion 312 is connected to one end of the second rod body 311. The first rotation portion 212 and the second rotation portion 312 are located on the same side of the base body 10.

By disposing the first rotation portion 212 and the second rotation portion 312 on the same side of the base body 10, the user can adjust the first adjustment assembly 20 and the second adjustment assembly 30 from one side of the base body 10 during aiming, thereby enabling easy operation.

As shown in FIG. 3, the first adjustment assembly 20 may further include first stop collar 25, and the first stop collar 25 is sleeved outside the first adjustment rod 21. As an example, the first stop collar 25 is sleeved outside the first rod body 211. An end of the first rod body 211 of the first adjustment rod 21 may be provided with third threaded hole 211a, and screw 26 may be threaded into the third threaded hole 211a to retain the first stop collar 25.

FIG. 4 is a partial exploded view of a first adjustment assembly according to an embodiment of the present disclosure. As shown in FIG. 4, the first adjustment assembly 20 further includes first pin seat 24, and the first pin seat 24 is sleeved outside the first adjustment rod 21. The first pin seat 24 is configured to be connected to the sight body 50. An inner side wall of the first pin seat 24 is provided with a plurality of tooth slots 241, and the plurality of tooth slots 241 are circumferentially distributed along the first pin seat 24.

The first adjustment rod 21 further includes pin 213 and third elastic member 214. A side wall of the first rotation portion 212 may be provided with pin hole 212a. The third elastic member 214 is located in the pin hole 212a, and the pin 213 is also located in the pin hole 212a. The pin 213 abuts against the inner side wall of the first pin seat 24 under the action of the third elastic member 214.

During the rotation of the first adjustment rod 21, the pin 213 moves in the plurality of tooth slots 241, and the pin 213 collides with the inner side wall of the first pin seat 24 under the action of the third elastic member 214 every time the pin moves past one tooth slot 241, thereby making a click sound. This facilitates the user to determine the angle of rotation of the first adjustment rod 21 according to the sound, thereby further facilitating the adjustment.

As shown in FIG. 1, the first adjustment assembly 20 further includes slider seat 22 and slider 23, and the slider seat 22 is connected to the base body 10. The slider 23 is provided with first threaded hole 23a. The slider 23 is sleeved outside the first adjustment rod 21 through the first threaded hole 23a, and is in threaded fit with the first adjustment rod 21. The slider 23 is slidably connected to the slider seat 22, so as to move relative to the slider seat 22 in a direction close to or away from the base body 10 with the rotation of the first adjustment rod 21.

The slider 23 is in threaded fit with the first adjustment rod 21, and is slidably connected to the slider seat 22. During the rotation of the first adjustment rod 21, the slider 23 is restricted by the slider seat 22 such that it does not rotate with the rotation of the first adjustment rod 21 but moves along the first adjustment rod 21. During the movement of the slider 23 along the first adjustment rod 21, it slides relative to the slider seat 22 and moves close to or away from the base body 10. Since the first adjustment rod 21 is connected to the sight body 50, the slider 23 will drive the sight body 50 to move away from the base body 10 together through the first adjustment rod 21 during the movement of the slider 23 away from the base body 10, thereby making the sight body 50 rotate around the second adjustment rod 31 and adjusting the pitch angle of the sight body 50.

The first adjustment rod 21 drives the slider 23 to move through threads, which can finely adjust the moving position of the slider 23 relative to the first adjustment rod 21, thereby improving the adjustment accuracy of the sight body 50.

As shown in FIG. 1, a side of the slider seat 22 away from the base body 10 is provided with first accommodating groove 22a, and a side wall of the first accommodating groove 22a is provided with first oblique guiding structure 221. A surface of the slider 23 is provided with second oblique guiding structure 231, and the slider 23 is located in the first accommodating groove 22a. The second oblique guiding structure 231 is mated with the first oblique guiding structure 221 to define the moving direction of the slider 23.

The first adjustment rod 21 is disposed along the second direction Y, and the slider 23 moves relative to the first adjustment rod 21 along the second direction Y during the rotation of the first adjustment rod 21. Through the mating of the first oblique guiding structure 221 and the second oblique guiding structure 231, the slider 23 moves obliquely relative to the slider seat 22 during the movement along the second direction Y, thereby moving close to or away from the base body 10. The oblique direction herein refers to a direction intersecting with the first direction X and the second direction Y, for example, a direction perpendicular to the first direction X and not perpendicular to the second direction Y.

The first oblique guiding structure 221 and the second oblique guiding structure 231 may include oblique guide groove 2211 and protrusion 2311.

FIG. 5 is a schematic structural view of a slider seat and a slider according to an embodiment of the present disclosure. As shown in FIG. 5, as an example, the first oblique guiding structure 221 includes the oblique guide groove 2211, the second oblique guiding structure 231 includes the protrusion 2311. The protrusion 2311 is located in the oblique guide groove 2211, and is slidably mated with the oblique guide groove 2211.

The mating of the protrusion 2311 and the oblique guide groove 2211 not only serves to connect the slider 23 and the slider seat 22 but also can limit the relative moving direction of the slider 23 and the slider seat 22.

Through the mating of the protrusion 2311 and the oblique guide groove 2211, the slider 23 can move relative to the slider seat 22 along the oblique guide groove 2211, and the moving direction of the slider 23 can be changed by adjusting the extending direction of the oblique guide groove 2211.

In other examples, the positions of the oblique guide groove 2211 and the protrusion 2311 may also be interchanged, that is, the oblique guide groove 2211 is located on a side wall of the slider 23, and the protrusion 2311 is located on the side wall of the first accommodating groove 22a.

As shown in FIG. 1, the base body 10 is provided with second accommodating groove 102, and the slider seat 22 is inserted into the second accommodating groove 102. The slider seat 22 is connected to the base body 10 through first connecting member 27.

Inserting the slider seat 22 in the second accommodating groove 102 and connecting the slider seat 22 and the base body 10 together through the first connecting member 27 makes the sight compact in structure and easy to assemble and disassemble. In addition, the fit clearance between the slider seat 22 and the first connecting member 27 enables the slider seat 22 to swing to a certain extent relative to the first connecting member 27 during adjustment of the second adjustment rod 31. The sight is a relatively precision optical device, and the adjustment of the sight body 50 by the first adjustment rod 21 and the second adjustment rod 31 is a fine adjustment within a small adjustment range. Therefore, even the fit clearance between the slider seat 22 and the first connecting member 27 is sufficient to provide a sufficient space for the movement of the sight body 50.

As an example, the first connecting member 27 is rod-shaped, and the first connecting member 27 is connected to the base body 10. A portion of the slider seat 22 inserted into the second accommodating groove 102 is provided with first through hole 22b, and the slider seat 22 is sleeved outside the first connecting member 27 through the first through hole 22b. The first through hole 22b is in clearance fit with the first connecting member 27 to enable the slider seat 22 to swing relative to the first connecting member 27.

As an example, a side wall of the second accommodating groove 102 may be provided with fourth through hole 102a, and the first connecting member 27 is inserted into the fourth through hole 102a.

The first connecting member 27 is a rod member, and the mating of the rod structure and the hole structure enables the slider seat 22 to swing to a certain extent relative to the first connecting member 27. The swing range of the slider seat 22 depends on the size of the clearance between the first through hole 22b and the first connecting member 27. A larger clearance between the first through hole 22b and the first connecting member 27 leads to a larger swing range of the slider seat 22, and a smaller clearance between the first through hole 22b and the first connecting member 27 leads to a smaller swing range of the slider seat 22.

As an example, the first through hole 22b is an elongated hole, and a cross section of the first connecting member 27 may be circular.

The first connecting member 27 can be inserted into the first through hole 22b. A rod diameter of the first connecting member 27 is not greater than a width of the elongated hole, and a length of the elongated hole is greater than the width of the elongated hole, which enables the first connecting member 27 to swing relative to the slider seat 22 along the length direction of the elongated hole. The swing range of the slider seat 22 can be changed by adjusting the length of the first through hole 22b.

As shown in FIG. 1, the second adjustment rod 31 is rotatably connected to the base body 10. The second adjustment assembly 30 further includes adjusting pin 32, and a side wall of the adjusting pin 32 is provided with second threaded hole 32a. The adjusting pin 32 is sleeved outside the second adjustment rod 31 through the second threaded hole 32a, and is in threaded fit with the second adjustment rod 31. The adjusting pin 32 is configured to be connected to the sight body 50.

Since the adjusting pin 32 is in threaded fit with the second adjustment rod 31, the adjusting pin 32 moves relative to the second adjustment rod 31 during the rotation of the second adjustment rod 31. Since the adjusting pin 32 is connected to the sight body 50, the sight body 50 can be driven to move along the second adjustment rod 31 through the adjusting pin 32 during the rotation of the second adjustment rod 31. The second adjustment rod 31 drives the adjusting pin 32 via the threaded fit, which can finely adjust the position of the adjusting pin 32, thereby improving the accuracy of adjusting the sight body 50.

As shown in FIG. 1, the base body 10 may be provided with fifth through hole 103, and the second adjustment rod 31 is inserted into the fifth through hole 103. The second adjustment assembly 30 may further include second pin seat 33 and second stop collar 34. The structure of the second pin seat 33 may be the same as that of the first pin seat 24, and the structure of the second stop collar 34 may be the same as that of the first stop collar 25. The second adjustment rod 31 may also include a pin and a third elastic member to engage with the second pin seat 33, which facilitates the user to determine the angle of rotation of the second adjustment rod 31 according to the sound, thereby further facilitating the adjustment.

An embodiment of the present disclosure further provides a sight, which may include sight body 50 and the external adjustment base for a sight as shown in any one of FIGS. 1 to 5, where the sight body 50 is connected to the external adjustment base.

The user can rotate the first adjustment rod 21 and the second adjustment rod 31 from the lateral side of the base body 10 to adjust the pitch angle and offset of the sight body 50, thereby improving the aiming accuracy. The operation is performed directly from the lateral side of the base body 10 during use, thereby enabling easy operation.

As shown in FIG. 1, one side of the sight body 50 close to the base body 10 is provided with first connecting portion 51 and second connecting portion 52, and the first connecting portion 51 and the second connecting portion 52 are axially spaced apart along the sight body 50.

The first connecting portion 51 is provided with second through hole 51a, and the first connecting portion 51 is sleeved outside the first adjustment rod 21 through the second through hole 51a. The second connecting portion 52 is provided with third through hole 52a, and the second connecting portion 52 is sleeved outside the second adjustment rod 31 through the third through hole 52a.

The first connecting portion 51 is coupled to the first adjustment rod 21 to enable the first adjustment rod 21 to rotate relative to the first connecting portion 51. During the rotation of the first adjustment rod 21, the first adjustment rod 21 is driven by the slider 23 to move close to or away from the base body 10, such that the first connecting portion 51 is driven to move close to or away from the base body 10, thereby completing the pitch adjustment of the sight body 50.

The second connecting portion 52 is coupled to the second adjustment rod 31 to enable the second adjustment rod 31 to rotate relative to the second connecting portion 52. During the rotation of the second adjustment rod 31, the adjusting pin 32 drives the second connecting portion 52 to move along the second adjustment rod 31, thereby driving the sight body 50 to move.

As shown in FIG. 1, the first connecting portion 51 is provided with third accommodating groove 51b, and the second through hole 51a is located on two opposite side walls of the third accommodating groove 51b. The slider seat 22 may be located in the third accommodating groove 51b to make the sight compact in structure.
