Description

Technical Field

[0001] This utility model relates to an explosion-proof LED tunnel light for mining. Background Technology

[0002] Explosion-proof LED tunnel lights for mining are explosion-proof lighting devices used in flammable and explosive environments such as coal mines and tunnels. These tunnel lights typically consist of a lamp housing, lamp glass, back cover, and mounting bracket. The explosion-proof structure prevents sparks or high temperatures generated by electrical components from contacting external flammable gases or dust, thus ensuring the safety of underground lighting.

[0003] Existing explosion-proof LED tunnel lights for mining generally use a main mounting bracket connected to a fixed support via bolts to fix the light body and adjust its angle. When adjusting the illumination angle, it is usually necessary to first remove the limit pin, then use tools to loosen the connecting bolts, swing the main mounting bracket to the desired position, and finally reinsert the limit pin and tighten the bolts. This structure has the following drawbacks: each angle adjustment requires the tightening and loosening of bolts and the insertion and removal of the limit pin, which must be done with tools, resulting in low adjustment efficiency; frequent bolt tightening and loosening operations are not only time-consuming but also prone to bolt wear or stripping, affecting long-term reliability; in special environments such as coal mines, the limit pin is frequently disassembled and reassembled, making it easy to lose, resulting in the tunnel light being unable to be quickly reset or fixed.
