Description

Technical Field

[0001] This utility model relates to the field of downlight technology, specifically a fixing structure for a downlight. Background Technology

[0002] Existing downlights often use threaded connections or fixed plates to clamp and rotate the lamp holder for fixation. Over long-term use, these connections are prone to loosening or falling off due to vibration or other factors, which not only affects the stability of the lighting but also poses safety hazards. Utility Model Content

[0003] This utility model provides a fixing structure for downlights. By setting a limiting part and cooperating with the elastic buckle to form a groove, the ribs are accurately locked and limited, improving the guiding and stability of the locking, and realizing the fixed connection between the lamp head and the lamp body. After installation, it cannot be disassembled, solving the problem of easy loosening and falling off of existing downlight connection methods.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a fixing structure for a downlight, comprising a lamp body, a lamp head, and a snap-fit ​​structure. The lamp body contains a circuit board and a light source. The lamp head is connected to the lamp body via the snap-fit ​​structure. The snap-fit ​​structure includes an elastic snap and a limiting part disposed on the edge of the lamp head, and a rib disposed on the inner side wall of the lamp body. The elastic snap is an elastic arm structure, with one end connected to the outer side wall of the lamp head and the other end being a free end. The limiting part and the elastic snap are spaced apart, forming a groove between them. The limiting part is connected to a guide strip, and the limiting part and the guide strip are integrally formed. The rib is a protruding structure, and the rib is engaged within the groove.

[0005] Preferably, the free end of the elastic buckle is provided with a first guide slope.

[0006] Preferably, the guide bar is provided with a second guide slope.

[0007] Preferably, the rib is provided with a groove, and the second guide slope cooperates with the groove.

[0008] Preferably, the ribs are provided in multiple portions and are evenly spaced along the circumference of the lamp body.

[0009] Preferably, the lamp head is equipped with a lens, which is located in front of the light source.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] The lamp head's limiting part and the elastic buckle form a slot. The elastic buckle's elastic arm structure and guide slope design allow the rib to slide quickly into the slot, realizing the rapid assembly of the lamp head and lamp body. Moreover, once the elastic buckle and rib are fastened, they cannot be disassembled, preventing the lamp from loosening or falling off due to vibration, accidental human touch, or other factors during long-term use. This ensures the stability of the connection between the lamp head and lamp body and maintains the continuous stability of the lighting function. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model is described below with reference to specific embodiments shown in the accompanying drawings. However, it should be understood that these descriptions are merely exemplary and not intended to limit the scope of the present utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of the present utility model.

[0020] It should also be noted that, in order to avoid obscuring the present invention with unnecessary details, only the structures and / or processing steps closely related to the solution according to the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0021] See Figures 1-5As shown, this specific embodiment adopts the following technical solution: it includes a lamp body, a lamp head, and a snap-fit ​​structure. The lamp body has a circuit board and a light source inside. The lamp head is connected to the lamp body through the snap-fit ​​structure. The snap-fit ​​structure includes an elastic snap and a limiting part disposed on the edge of the lamp head, and a rib disposed on the inner side wall of the lamp body. The elastic snap is an elastic arm structure, one end of which is connected to the outer side wall of the lamp head, and the other end is a free end. The limiting part and the elastic snap are spaced apart, forming a groove between them. The limiting part is connected to a guide strip, and the limiting part and the guide strip are integrally formed. The rib is a protruding structure, and the rib is snapped in the groove. The limiting part and the elastic snap together limit the connection between the lamp head and the lamp body, and the connection cannot be disassembled after assembly.

[0022] The elastic buckle has a first guide slope at its free end, which guides the rib to slide into the slot and reduces resistance. The guide bar has a second guide slope. The rib has a groove, and the second guide slope cooperates with the groove to contact the rib first and guide the rib to move towards the free end of the elastic buckle during the rotation of the lamp head. There are multiple ribs, which are evenly spaced along the circumference of the lamp body. The lamp head has a lens inside, which is located in front of the light source.

[0023] The working principle of this specific embodiment is as follows: During installation, align the lamp head with the opening of the lamp body, so that the guide strip of the lamp head is aligned with the rib inside the lamp body. Apply rotational force to drive the lamp body to rotate. The guide strip acts as a guide for the rotation path. Its second guide slope first contacts the groove on the rib. During rotation, the second guide slope cooperates with the groove. The second guide slope guides the rib to move towards the free end of the elastic buckle, forcing the elastic buckle to deform. The extension direction of the guide strip determines the movement trajectory of the rib, ensuring that the lamp body rotates smoothly along the preset rotation direction. As the lamp body rotates, the rib, guided by the guide strip, slides along the first guide slope of the free end of the elastic buckle and passes over the elastic buckle. After completely passing the blocking position of the elastic buckle, the elastic deformation of the elastic buckle recovers, and it engages with the protruding structure of the rib. At the same time, the limiting part abuts against the rib to form a limit, and finally the fixed connection between the lamp head and the lamp body is completed.

[0024] This specific embodiment forms a slot through the limiting part of the lamp head and the elastic buckle. The elastic arm structure and guide slope design of the elastic buckle allow the rib to slide quickly into the slot, realizing the quick assembly of the lamp head and the lamp body. Moreover, once the elastic buckle and the rib are fastened, they cannot be disassembled, preventing the lamp from loosening or falling off due to vibration, accidental human touch or other factors during long-term use. This ensures the stability of the connection between the lamp head and the lamp body and maintains the continuous stability of the lighting function.

[0025] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and not restrictive in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description; thus, all variations falling within the meaning and scope of equivalents of the claims are included within this invention.

[0026] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
