Description

Technical Field

[0001] This utility model relates to the field of shaft lights, and in particular to a shaft light that can be adapted to multiple specifications. Background Technology

[0002] Shaft lights are a type of lighting fixture that are often installed inside elevator shafts to provide ample illumination, making it easier for personnel to inspect, check, and conduct rescue operations on the elevator.

[0003] Existing shaft lights consist of a base, junction box, light source board, and lampshade. While they offer good lighting effects and stable structure, they also present other problems during use. For example, they lack compatibility with multiple specifications, the main light-emitting component is relatively simple and cannot be freely replaced in some cases of the same model, resulting in poor flexibility. Furthermore, it is inconvenient to replace the light source board. During installation, the light source board is either directly fixed with screws or connected magnetically. With screw fixing, tools are required for disassembly and assembly, while the magnetic connection method has poor stability, with significant magnetic degradation under heat, making it prone to falling off. To solve the above problems, we propose a shaft light that can be adapted to multiple specifications. Utility Model Content

[0004] The purpose of this invention is to provide a shaft light that can be adapted to multiple specifications, solving the problems of existing shaft lights not having the function of adapting to multiple specifications and the inconvenience of replacing the light source board.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a shaft light adaptable to multiple specifications, including a base, a first connector and a second connector respectively placed inside the base, cables installed at the ports of the first connector and the second connector, a junction box installed on the top of the base, wiring grooves symmetrically opened on the surface of the junction box, a light source plate placed on the top of the junction box, a first cylinder symmetrically bolted to the top of the junction box, a second cylinder slidably sleeved on the top of the first cylinder, a connecting plate rotatably connected inside the first cylinder, a limit spring installed between the top of the connecting plate and the second cylinder, a fixing plate bolted to the top of the second cylinder, and a limit pin installed at the bottom of the fixing plate.

[0006] By adopting the above technical solution, the product can be adapted to multiple specifications, which improves the applicable environment of the product. The main light-emitting part can be freely replaced with the same model, which is highly practical. At the same time, it is easy to replace the light source board, and the operation is simple and labor-saving, which improves the maintenance efficiency of personnel, and has good flexibility and stability.

[0007] The present invention is further configured such that: a lower clamp is installed inside the base, and an upper clamp is engaged with the top of the lower clamp.

[0008] By adopting the above technical solution, the cables on the first connector and the second connector can be fixed by setting the lower clamp and the upper clamp.

[0009] The present invention is further configured such that: four mounting slots are provided on the top of the base.

[0010] By adopting the above technical solution, the installation slot makes it easy for personnel to fix the base to the elevator shaft wall with screws, reducing the trouble of drilling holes in the base temporarily.

[0011] The present invention is further configured such that: a limiting plate is fixedly sleeved on the surface of the limiting pin, and the diameter of the limiting plate is larger than the diameter of the through hole on the light source plate.

[0012] By adopting the above technical solution and setting the limiting plate, the limiting effect on the light source board can be improved, and the light source board can be prevented from moving back and forth after installation.

[0013] The present invention is further configured such that a transparent lampshade is threadedly connected to the top of the junction box.

[0014] By adopting the above technical solution, the transparent lampshade can provide dust protection and extend the service life of the light source board.

[0015] The present invention is further configured such that the surfaces of the base and the junction box are coated with anti-corrosion coating.

[0016] By adopting the above technical solution and applying anti-corrosion coating, the anti-corrosion and moisture-proof effects of the base and junction box surface can be improved.

[0017] The present invention is further configured such that: the top of the base has four notches, which are in the shape of a cross.

[0018] The above technical solution allows for arbitrary changes in the direction of cable entry and exit, and the multi-position installation slot design adapts to different installation environments.

[0019] In summary, this utility model has the following beneficial effects:

[0020] 1. This utility model involves first placing the first and second connectors into the base, then straightening the cable and pulling it out from the corresponding notch. After straightening the cable, the upper clamp is placed on the cable and pressed down into the lower clamp for fixation. Then, the cable routing groove on the junction box is aligned with the cable and installed onto the base. Finally, the light source board and transparent lampshade are connected in sequence. This design allows for multi-specification compatibility, improves the product's applicability, and enables the main light-emitting part to be freely replaced with the same model, resulting in high practicality.

[0021] 2. This utility model allows for easy replacement of the light source board when it is damaged. The transparent lampshade is first rotated and removed from the junction box. After the transparent lampshade is removed, the fixing plate is grasped and pulled outward. When the fixing plate is pulled outward, it will drive the second cylinder and the limiting pin to move outward. When the limiting pin moves outward, it will move out of the through hole in the junction box and the light source board. Then, the fixing plate is rotated to make the limiting pin misalign with the light source board. This makes it easy to replace the light source board, and the operation is simple and labor-saving, improving the maintenance efficiency of personnel. It also has good flexibility and stability.
