The present invention relates to a ceiling fan with a lamp, and more particularly to a quick assembling structure for a ceiling fan with a lamp.
Conventional ceiling fans are mostly fixed to the ceiling. In order to save the installation space of a lamp, a ceiling fan is usually combined with a lamp under the ceiling fan. With the setting of the lamp, the ceiling fan has the lighting effect. However, the lamp is integrally connected to the ceiling fan, so that users cannot change the style of the lamp according to different preferences. It is also impossible to change the lighting brightness of the lamp according to different usage requirements, which causes great inconvenience in use.
An improved ceiling fan with a lamp is developed on the market. As shown in
The primary object of the present invention is to provide a quick assembling structure for a ceiling fan with a lamp, which improves the convenience and safety for the assembly of the ceiling fan and the lamp.
In order to achieve the above object, the present invention provides a quick assembling structure, mounted to a ceiling fan. The ceiling fan has a ceiling fan body and a lamp under the ceiling fan body. The quick assembling structure comprises a first seat, a second seat, and a plurality of elastic plates. The first seat is disposed on one of the ceiling fan body and the lamp. The first seat has a first peripheral wall. The first peripheral wall has a plurality of positioning members extending transversely. The positioning members are arranged at intervals. The second seat is disposed on the other one of the ceiling fan body and the lamp. The second seat has a second peripheral wall to be connected to the first peripheral wall. The second seat has an opening on a receiving side of the second peripheral wall. The second peripheral wall has recesses that are recessed transversely and correspond to the respective positioning members. The recesses each extend longitudinally. The recesses each have one side communicating with the opening for positioning and receiving the positioning members. The recesses each have another side provided with a guide hole. The guide hole extends and tapers toward a tightening end along a guide direction via a guide path. The guide holes of the recesses are configured to guide the respective positioning members. The tightening ends of the guide holes of the recesses are configured to secure the respective positioning members. One side of the guide hole, adjacent to the opening, is recessed to form an accommodating groove. The accommodating groove extends from the guide hole toward the opening. The accommodating groove is configured to accommodate a corresponding one of the positioning members. The elastic plates are disposed on the second seat. The elastic plates each correspond to the guide path of the guide hole. The elastic plates each have a fixed end and an open end. The fixed end is fixedly connected to the second seat. The open end has two push portions and a contact portion. In a normal state, the open end of each elastic plate is in the guide path of the corresponding guide hole, and the open end of each elastic plate is located between the accommodating groove of the corresponding guide hole and the tightening end. The push portions of the open end of each elastic plate extend toward the accommodating groove of the corresponding guide hole and the tightening end for the corresponding positioning member to push against the push portions. In the normal state, the contact portion of the open end of each elastic plate is in contact with the second seat. When the elastic plates are in a stressed state, the push portions and the contact portion of the open end of each elastic plate are away from the guide path.
In the quick assembling structure provided by the present invention, when the positioning members are inserted into the recesses and the guide holes, the positioning members are pushed to pass through the push portions of the elastic plates for the positioning members to be secured at the tightening ends of the guide holes of the recesses, so that the first seat is combined with the second seat to quickly complete assembly of the ceiling fan and the lamp. When the positioning members leave the tightening ends of the guide holes and the push portions of the elastic plates, the accommodating grooves of the guide holes are configured to prevent the positioning members from leaving the guide holes, thereby preventing the lamp from falling. After the positioning members are pushed against the elastic plates, the contact portions of the elastic plates touch the second seat through its elastic force for a user to confirm the position of the positioning members through a touch feeling or a touch sound.
Embodiments of the present invention will now be described, by way of example only, with reference to the accompanying drawings.
The first seat 10 is disposed on one of the ceiling fan body 210 and the lamp 220. The first seat 10 has a first peripheral wall 11. In the first embodiment of the present invention, the first seat 10 is disposed on the ceiling fan body 210. The first seat 10 is a hollow seat. The first peripheral wall 11 is an annular wall. The first peripheral wall 11 has a plurality of positioning members 12 extending transversely. The positioning members 12 extend inwardly from the inner side of the first peripheral wall 11. The positioning members 12 are arranged at intervals and equidistant from each other. The positioning members 12 are located on the same plane. The first seat 10 has a receiving opening 13 on a receiving side of the first peripheral wall 11.
The second seat 20 is disposed on the other one of the ceiling fan body 210 and the lamp 220. The second seat 20 has a second peripheral wall 21 to be connected to the first peripheral wall 11. In the first embodiment of the present invention, the second seat 20 is disposed on the lamp 220. When the second peripheral wall 21 is connected to the first peripheral wall 11, the second peripheral wall 21 is located inside the first peripheral wall 11. The second seat 20 is a hollow seat. The second peripheral wall 21 is an annular wall. The second seat 20 has an opening 22 on a receiving side of the second peripheral wall 21. The second peripheral wall 21 has recesses 23 that are recessed transversely and correspond to the respective positioning members 12. The recesses 23 are recessed inwardly from the outer side of the second peripheral wall 21 of the second seat 20. The recesses 23 each extend longitudinally. The recesses 23 each have one side communicating with the opening 22 for positioning and receiving the positioning members 12. The recesses 23 each have another side provided with a guide hole 24. The guide hole 24 extends and tapers toward a tightening end 25 along a guide direction 401 via a guide path 402. The guide direction 401 is a circumferential direction of the second seat 20. The tightening end 25 of the guide hole 24 corresponds in size to the positioning member 12, so that the guide hole 24 can guide the positioning member 12. The tightening end 25 of the guide hole 24 is configured to secure the positioning member 12. In addition, one side of the guide hole 24, adjacent to the opening 22, is recessed to form an accommodating groove 26 corresponding to the positioning member 12. The accommodating groove 26 extends from the guide hole 24 toward the opening 22. The accommodating groove 26 is configured to accommodate the positioning member 12.
The elastic plate 30 is disposed on the second seat 20 and corresponds to the guide path 402 of the guide hole 24. The elastic plate 30 has a fixed end 31 and an open end 32. The fixed end 31 of the elastic plate 30 is fixedly connected to the second seat 20. The open end 32 of the elastic plate 30 has two push portions 321 and a contact portion 322. In the normal state, the open end 32 of the elastic plate 30 is in the guide path 402 of the corresponding guide hole 24, and the open end 32 of the elastic plate 30 is located between the accommodating groove 26 of the corresponding guide hole 24 and the tightening end 25. The push portions 321 of the open end 32 of the elastic plate 30 extend toward the accommodating groove 26 of the corresponding guide hole 24 and the tightening end 25 for the corresponding positioning member 12 to push against the push portions 321. In the normal state, the contact portion 322 of the open end 32 of the elastic plate 30 is in contact with the second seat 20. When the elastic plate 30 is in a stressed state, the push portions 321 and the contact portion 322 of the open end 32 of the elastic plate 30 are away from the guide path 402.
Referring to
When the quick assembling structure 100 is to be disassembled or replaced, the second seat 20 with the lamp 220 is rotated in an opposite direction. The positioning member 12 is moved toward the corresponding recess 23 via the guide path 402 in a direction opposite to the guide direction 401, so that the positioning member 12 is pushed to pass through the push portions 321 of the elastic plate 30 to be out of the guide hole 24 and the recess 23. That is, the second seat 20 is separated from the first seat 10, so that the lamp 220 is separated from the ceiling fan body 210. In this way, the lamp 220 can be easily replaced.
It is worth mentioning that if the ceiling fan 200 runs and vibrates for a long time, it is easy to cause the positioning members 12 to loosen or displace, resulting in that the positioning members 12 are moved from the tightening ends 25 of the guide holes 24 towards the recesses 25. At this time, the positioning members 12 can be accommodated in the accommodating grooves 26 in the guide holes 24 to prevent the positioning members 12 from moving to the recesses 23. This prevents the second seat 20 from being separated from the first seat 10 to cause the lamp 220 to fall. The present invention improves the safety of assembly effectively.
After the positioning member 12 is pushed against the corresponding elastic plate 30, the push portions 321 and the contact portion 322 of the open end 32 of the elastic plate 30 are away from the guide path 402. Then, the contact portion 322 of the elastic plate 30 touches the second seat 20 through its elastic force for the user to confirm the position of the positioning member 12 through a touch feeling or a touch sound.
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.
