[0001] This utility model relates to the field of track light technology, specifically a track light driver power supply with a protective structure. Background Technology

[0002] Track lights are widely used in various scenarios such as commercial shops, showrooms, and home living rooms due to their advantages such as flexible installation and adjustable illumination angle.

[0003] Most existing track light dust covers are fixed with screws or hinged to the track light using only a damping shaft or torsion spring. The former requires the use of specialized tools to disassemble multiple parts when it is necessary to inspect or replace the light source module or wiring terminals inside the light body, which is cumbersome and time-consuming. The latter can open and close the dust cover, but the cover is prone to loosening and shaking due to vibration when the track light is in use. Utility Model Content

[0004] The purpose of this utility model is to provide a track light driver power supply with a protective structure, which can limit the rotation of the upper lamp cover, protect the internal light source module of the track light, and facilitate disassembly and maintenance; and the multi-directional limiting can make the angle of the upper lamp cover stable when it is opened and closed, and it is not easy to loosen and detach from the lamp body.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a track light driver power supply with a protective structure, including a housing and a cover plate slidably connected to the top of the housing via a sliding structure, wherein one end of the housing is provided with a top cover for inserting the light body;

[0006] The top cover includes a lower lamp cover, an upper lamp cover, and a connecting member. The upper lamp cover is rotatably connected to the connecting member through a rotating structure. The lower lamp cover is snapped into the connecting member through a snap-fit ​​structure. The connecting member is provided with a limiting structure for limiting the rotation of the upper lamp cover.
