Description

Technical Field

[0001] This utility model relates to the field of safety light technology, specifically an explosion-proof mine safety light. Background Technology

[0002] Explosion-proof mine safety lights are lighting devices specifically designed for explosive environments such as underground mines. They are mainly used in mine tunnels and roadways to provide safe and stable lighting for mining operations, ensuring the normal operation and safety of miners. They typically possess explosion-proof, dustproof, and impact-resistant characteristics. Core components generally include a lamp holder, lighting source, explosion-proof protective structure, and mounting components. With the development of the mining industry and the improvement of safety standards, LED lamp beads, due to their low energy consumption and long lifespan, have gradually become the mainstream lighting source for explosion-proof mine safety lights. At the same time, the explosion-proof protective structure is constantly being optimized to adapt to the complex and harsh working environment of mines, ensuring that the equipment will not cause explosions during use, thus providing important protection for safe mine production.

[0003] In existing technologies, the explosion-proof mesh cover of explosion-proof mine safety lights, as an important explosion-proof protective component, has significant defects in its connection method. Most products use fixed connections or screw connections to combine the explosion-proof mesh cover with the lamp holder. This connection structure is quite inadequate in the dusty mining environment. Due to the high dust levels in mine tunnels and roadways, dust easily accumulates on the surface of the lamp cover and explosion-proof mesh cover after a period of use, affecting the lighting effect. Excessive dust accumulation may also cause problems such as increased equipment temperature. Therefore, regular wiping and cleaning of safety lights is necessary. However, the disassembly process of fixed or screw-connected explosion-proof mesh covers is cumbersome, requiring special tools and involving multiple steps, resulting in a long cleaning time. This not only affects the normal progress of mining operations but also increases the time cost of maintenance, making it difficult to meet the demand for convenient equipment maintenance in efficient and safe mining production. Therefore, we propose an explosion-proof mine safety light. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an explosion-proof mine safety lamp, which solves the aforementioned problems.

When replacing, the rubber anti-slip strips 16 can increase the operating friction. Push the connecting cylinder 14 upward to make the sliders 17 exit the groove 10. At the same time, the sliders 17 squeeze the clamping member 3. Then rotate the connecting cylinder 14 so that the sliders 17 are aligned with the opening at the bottom of the clamping groove 5 and slide out. Then the lamp cover 6 can be wiped.
