[0024] This utility model embodiment provides a lighting structure suitable for prefabricated suspended ceilings, such as... Figure 1-4 The device includes a lighting fixture and a connecting part. The connecting part consists of a base plate 1 and a circumferential telescopic mechanism. The connecting part is located on the upper side of the ceiling. The circumferential telescopic mechanism is used to adjust the circumference of the connecting part to accommodate round lighting fixtures of different sizes.

[0025] The circumferential telescopic mechanism in this technical solution includes an inner ring 2, an outer ring 3, several sliding rods 4, a ring gear 5, and several pinions 6. The inner ring 2 and the outer ring 3 are concentrically arranged, and several sliding grooves 7 are opened at equal angles on the circumference of the inner ring 2 and the outer ring 3. The sliding rods 4 are slidably connected in the sliding grooves 7. The ring gear 5 is rotatably connected between the outer ring 3 and the base plate 1. Several pinions 6 are rotatably connected on the base plate 1 and are arranged between the inner ring 2 and the outer ring 3. A rack 8 is provided on the side of the sliding rod 4 near the pinion 6. The pinion 6 meshes with the ring gear 5 and the rack 8 respectively. By rotating the ring gear 5, the pinion 6 can drive the rack 8 to move linearly, thereby realizing the telescopic movement of the sliding rod 4 on the inner and outer rings 3, and realizing the purpose of changing the circumference size of the connecting part. Several mounting holes 9 are opened on the inner ring 2, the outer ring 3, and the sliding rods 4. That is, the inner ring 2, the outer ring 3, and the telescopic rods are all used to pass through the ceiling and fix the light fixture.

[0026] In the embodiments of this case, such as Figure 3 As shown, the lamp part includes a lamp holder 10 and a lamp cover 11. A light source 12 is provided in the lamp holder 10, and a mounting through hole 13 corresponding to the mounting hole 9 is opened in the lamp holder 10.

[0027] A connecting rod 18 is provided at the center of the base plate 1, and a through hole is provided at the center of the corresponding lamp holder 10. The through hole of the lamp holder 10 is fitted onto the connecting rod 18 for fixation.

[0028] Furthermore, the connection between the connecting part and the lamp part can be divided into two parts. The first is the pre-connection at the center of the lamp holder 10, which includes, but is not limited to, the method in the embodiment of this case, such as... Figure 3As shown, the connecting rod 18 in this embodiment has an external thread, and the lamp holder 10 is fixed to the connecting rod 18 by engaging with the threaded sleeve 14.

[0029] The above technical solution is further described as follows: Figure 4 As shown, the sliding groove 7 is L-shaped. The L-shaped sliding groove 7 provides a limiting function for the sliding rod 4, preventing the sliding rod 4 from falling out.

[0030] like Figure 4 As shown, in order to facilitate the rotation of the ring gear 5, a ring 15 is connected to the outer circumference of the ring gear 5 in this embodiment, and the ring gear 5 is driven to rotate through the ring 15.

[0031] Furthermore, such as Figure 2 and Figure 4 As shown, the base plate 1 and the outer ring 3 are provided with rotating grooves 16, and the ring gear 5 is provided with convex rings 17 on the upper and lower sides, and the convex rings 17 are slidably connected in the rotating grooves 16.

[0032] Regarding the connection between the lampshade 11 and the lamp holder 10, including but not limited to the manner described in the embodiment of this case, the lampshade 11 and the lamp holder 10 are connected by threads.

[0033] Preferably, the number of sliding rods 4 is six.

[0034] Working principle: During the assembly of the prefabricated ceiling, the connecting part is first set at the upper end of the ceiling. Then, according to the circumference of the part where the light fixture is installed, the extension and retraction of the sliding rod 4 of the connecting part is adjusted. Specifically, by rotating the ring 15, the ring gear 5 is driven to rotate, which in turn drives the small gear 6 to rotate. The small gear 6 then drives the sliding rod 4 to extend and retract. Only one through hole matching the connecting rod 18 needs to be opened on the ceiling. After the through hole in the center of the lamp holder 10 passes through the connecting rod 18, it is threadedly connected to the connecting rod 18 by the threaded sleeve 14 to achieve pre-fixation. Then, the lamp holder 10 is installed by threading through the mounting through hole 13 of the lamp holder 10 and connecting to the mounting holes 9 of the sliding rod 4, outer ring 3, and inner ring 2 (one or more of them can be selected). Then, the light source 12 is installed in the lamp holder 10 and connected to the relevant circuit. Finally, the lamp cover 11 is installed on the lamp holder 10.

[0035] In summary, this utility model uses a connecting part to fix the lamp part to the ceiling. The sliding rod 4 of the circumferential telescopic mechanism of the connecting part can adapt to the installation requirements of round lamps of different sizes, thereby improving the applicability of the product.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
