[0002] An elevator refers to a permanent transportation device that serves several specific floors in a building, and its car runs on at least two rigid tracks perpendicular to the horizontal plane or with an inclination angle less than 15° to the plumb line.

[0003] In the prior art, elevators are common equipment in high-rise buildings, which provide great convenience for going upstairs. Since elevators are enclosed spaces, lighting lamps are often installed in elevators for lighting to facilitate people's activities in the elevator.

[0004] However, most of the existing lighting lamps are lighting strips simply clamped on the top surface of the elevator through an outer shell. When the elevator suddenly stops and starts, vibrations will occur, which easily loosens or even drops the outer shell of the lighting lamp simply clamped on the top of the elevator, posing a safety hazard. Using bolts for fixation will also loosen due to the vibrating elevator. Summary of the Utility Model

[0026] In order to clearly and completely describe the objectives, technical solutions of the present utility model, and make the advantages more clear and understandable, the following further details the embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present utility model, rather than all of the embodiments, and are only used to explain the embodiments of the present utility model, not to limit the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0027] Embodiment 1, please refer to Figures 1 - 6 , the present utility model provides a technical solution: an elevator lighting device and system. An annular groove 4 is provided on the surface of the top surface 1 of the elevator. A first notch 3 is provided at the opening of the annular groove 4. A limit groove 7 is provided on the inner wall surface of the annular groove 4. When the limit block 12 is stuck in the limit groove 7, when it is necessary to continue rotating the connecting block 8, resistance from the limit block 12 will be encountered, and a relatively large force is required to drive the connecting block 8 to rotate. Therefore, when the limit block 12 is stuck in the limit groove 7, the stability of the lighting lamp housing on the top surface 1 of the elevator is achieved. A through groove 6 is provided on the inner wall of the annular groove 4 at the first notch 3.

[0028] A connecting block 8 is fixed on the outer surface of the side shell 9. The connecting block 8 is made of rubber material, and the rubber material has a shock-absorbing effect. When the elevator suddenly stops or starts and generates vibrations, the connecting block 8 will absorb the shock, and the reaction force of the connecting block 8 will act on the inner wall of the annular groove 4, making the connecting block 8 more stable in the annular groove 4. A receiving groove 13 is provided on the inner surface of the connecting block 8. A spring 14 is fixed on the inner wall surface of the receiving groove 13, and a limit block 12 is provided on the inner wall of the receiving groove 13.

[0029] On the basis of the first embodiment, in order to achieve the stability of the elevator lighting lamp housing, a positioning groove 5 is formed on the surface of the elevator top surface 1 adjacent to the annular groove 4. A connecting shell 10 is fixed on the surface of the side shell 9, and an outer plate 2 is fixed at the end of the connecting shell 10. The side shell 9, the connecting shell 10 and the outer plate 2 form a lighting lamp housing assembly, and the lighting lamp housing assembly is made of a hollow transparent material. A positioning block 11 is fixed on the side surface of the outer plate 2 adjacent to the connecting shell 10.

[0030] A second notch 15 is formed at the inner wall of the receiving groove 13 near the port. A baffle 16 is arranged inside the spring 14. The baffle 16 is located on the surface of the inner wall of the receiving groove 13 adjacent to the second notch 15. A limiting block 12 is fixed on the surface of the baffle 16, and an arc surface is formed on the outer surface of the limiting block 12.

[0031] Multiple groups of positioning grooves 5 are formed, and the multiple groups of positioning grooves 5 are spirally distributed on the surface of the elevator top surface 1. Multiple groups of positioning blocks 11 are provided, and the multiple groups of positioning blocks 11 are spirally distributed on the inner surface of the outer plate 2. The positioning blocks 11 correspond to the positioning grooves 5, and the positioning blocks 11 are clamped in the positioning grooves 5, and the two are movably connected, which plays a positioning role for the outer plate 2 on the elevator top surface 1 and prevents external dust from entering the housing interior through the through groove 6.

[0032] The diameter of the side shell 9 is the same as that of the first notch 3, the diameter of the connecting block 8 is the same as that of the annular groove 4 and the through groove 6, and the diameter of the annular groove 4 is greater than that of the first notch 3, and the connecting block 8 corresponds to the through groove 6. Therefore, the connecting block 8 can only enter the annular groove 4 through the through groove 6.

[0033] Multiple groups of limiting grooves 7 are formed, and the multiple groups of limiting grooves 7 are circumferentially distributed on the bottom surface of the inner wall of the annular groove 4. Multiple groups of limiting blocks 12 are provided, and the multiple groups of limiting blocks 12 are circumferentially distributed on the inner surface of the connecting block 8. The limiting blocks 12 correspond to the limiting grooves 7, and the limiting blocks 12 are clamped in the limiting grooves 7. When the connecting block 8 needs to be rotated further, it will encounter the resistance of the limiting blocks 12, and a greater force is required to drive the connecting block 8 to rotate. Therefore, when the limiting blocks 12 are clamped in the limiting grooves 7, the stability of the lighting lamp housing on the elevator top surface 1 is achieved.

[0034] The bottom size of the baffle 16 is the same as the bottom size of the inner wall of the receiving groove 13, the bottom size of the limiting block 12 is the same as the size of the second notch 15, and the bottom size of the receiving groove 13 is greater than the size of the second notch 15, and the baffle 16 corresponds to the receiving groove 13. The baffle 16 is clamped in the receiving groove 13, and the two are movably connected. Therefore, the baffle 16 will not break away from the receiving groove 13, and the limiting block 12 will not break away from the connecting block 8.

[0035] In actual use, the connecting block 8 is made of rubber. When installing the outer shell of the illuminating lamp, first align the positioning block 11 with the positioning groove 5 and snap it in. At the same time, align the connecting block 8 with the through groove 6 and snap it in. Then, hold the outer plate 2 by hand and drive the side shell 9 to rotate. The rotation of the side shell 9 will drive the connecting block 8 to rotate in the annular groove 4. Since the outer surface of the limiting block 12 is an arc surface, when the connecting block 8 enters the annular groove 4 through the through groove 6, the limiting block 12 will be squeezed by the inner wall of the annular groove 4 and received into the receiving groove 13. Continue to rotate the connecting block 8. When the limiting block 12 snaps into the limiting groove 7, when it is necessary to continue rotating the connecting block 8, resistance from the limiting block 12 will be encountered, and a relatively large force is required to drive the connecting block 8 to rotate. Therefore, when the limiting block 12 is snapped into the limiting groove 7, the stability of the outer shell of the illuminating lamp on the top surface 1 of the elevator is achieved. Moreover, the connecting block 8 is made of rubber material, and the rubber material has a shock-absorbing effect. When the elevator suddenly stops or starts and generates vibrations, the connecting block 8 will absorb the shock, and the reaction force of the connecting block 8 will act on the inner wall of the annular groove 4, making the connecting block 8 more stable in the annular groove 4.
