BLADE INSTALLATION STRUCTURE OF CEILING FAN
A blade installation structure of a ceiling fan includes a blade, a coupling seat, and an elastic member. The blade has a connecting portion. The connecting portion has a through hole. The coupling seat has a slot. A displacement space is defined in the slot. The elastic member includes an elastic portion and an abutting portion connected to the elastic portion. The abutting portion abuts against the through hole of the blade, and the elastic portion is confined within the through hole of the blade, so that the blade is locked and fixed to the coupling seat. The blade installation structure of the ceiling fan has the advantages of quick installation and increased blade support.
The present invention relates to a ceiling fan, and more particularly to a blade installation structure of a ceiling fan.
BACKGROUND OF THE INVENTIONIn general, a conventional ceiling fan includes a ceiling fan body and a plurality of blade frames connected to the outside of the ceiling fan body. Each blade frame is provided with a blade. Each blade is locked and fixed to the corresponding blade frame by screws to complete the assembly of the ceiling fan and the blades, so that the ceiling fan can drive the blades to rotate smoothly and stably.
However, the assembly process is complicated, cumbersome and time-consuming. If the ceiling fan is to be moved or replaced, the large number of screws will cause inconvenience in disassembly and assembly. Accordingly, the inventor of the present invention has devoted himself based on his many years of practical experiences to solve these problems.
SUMMARY OF THE INVENTIONThe primary object of the present invention is to provide a blade installation structure of a ceiling fan, which has the advantages of quick installation and increased blade support.
In order to achieve the above object, the present invention provides a blade installation structure of a ceiling fan. The ceiling fan has a motor unit. The motor unit has a motor and a rotating portion. The motor drives the rotating portion to rotate. The blade installation structure comprises a blade, a coupling seat, and an elastic member. The blade has a connecting portion. A pushing portion is formed on an outer edge of the connecting portion. The connecting portion has a through hole. The coupling seat has one end fixed to the rotating portion of the motor. The coupling seat has a slot. A displacement space is defined in the slot. The coupling seat has a first opening for the connecting portion of the blade to be inserted into the slot from the first opening and the displacement space. The elastic member corresponds to the connecting portion of the blade and is disposed in the slot of the coupling seat. The elastic member includes an elastic portion and an abutting portion connected to the elastic portion. The elastic portion has a fixed end adjacent to the first opening and a free end away from the first opening. The fixed end of the elastic portion is fixed to the coupling seat. The free end of the elastic portion is connected to the abutting portion. The elastic portion and the abutting portion of the elastic member correspond to the pushing portion and the through hole of the blade, respectively. When the elastic portion is in a normal state, the elastic portion is oblique from the fixed end toward the free end, the elastic portion is in the displacement space of the slot corresponding to the pushing portion of the blade, and the abutting portion of the elastic member is in the displacement space of the slot corresponding to the through hole of the blade, so that the elastic portion and the abutting portion are in a normal state position. When the elastic portion is pushed and elastically displaced by the pushing portion of the blade to be in a stress state, the elastic portion and the abutting portion are in a stress state position away from the displacement space of the slot. When the elastic portion and the abutting portion are restored to be in the normal state, the abutting portion abuts against the through hole of the blade.
In the blade installation structure of the ceiling fan provided by the present invention, the abutting portion abuts against the through hole of the blade, and the elastic portion is confined within the through hole of the blade, so that the blade is locked and fixed to the coupling seat. The blade installation structure of the ceiling fan has the advantages of quick installation and increased blade support.
Embodiments of the present invention will now be described, by way of example only, with reference to the accompanying drawings.
The blade 10 has a connecting portion 11. A pushing portion 12 is formed on the outer edge of the connecting portion 11. The connecting portion 11 has a through hole 13. The inner peripheral wall of the through hole 13 has a first surface 131.
The coupling seat 20 has one end fixed to the rotating portion 240 of the motor 230. The coupling seat 20 has a slot 21. A displacement space 21a is defined in the slot 21. The coupling seat 20 has a first opening 22 and a second opening 23. The first opening 22 allows the connecting portion 11 of the blade 10 to be inserted into the slot 21 from the first opening 22 and the displacement space 21a. The coupling seat 20 has a support portion 24 adjacent to the second opening 23. One side of the coupling seat 20, facing away from the motor 230, is formed with two first locking holes 25. The slot 21 is located below the first locking holes 25 and the second opening 23. The coupling seat 20 has a third opening 26 corresponding in position to the first locking holes 25 and opposite to the first locking holes 25. The third opening 26 communicates with the first opening 22.
The hanging member 40 has a hook 41 corresponding to the hanging hole 341. When in use, the hook 41 is inserted in the hanging hole 341 to apply a force, so that the elastic portion 31 and the abutting portion 32 of the elastic member 30 are elastically displaced to be in the stress state position 30b, so as to disengage the blade 10 from the slot 21 of the coupling portion 20.
It is worth mentioning that the stop piece 342 is perpendicular to the hanging portion 34. The stop piece 342 extends from the hanging portion 34 to the outside of the support portion 24. When the elastic portion 31 and the abutting portion 32 are in the normal state, the stop piece 342 is supported by the support portion 24. Thereby, when the motor 230 drives the blade 10 to rotate, the blade 10 will be subjected to the outward centrifugal force. Through the stop piece 342, the elastic member 30 can be prevented from being deformed and has the effect of supporting the blade 10.
Although particular embodiments of the present invention have been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the present invention. Accordingly, the present invention is not to be limited except as by the appended claims.
