[0002] In traditional industrial applications, especially in places like coal mines with complex environment and extremely high safety requirements, explosion-proof lamps as important lighting equipment, their structure directly affects work efficiency and personnel safety.
[0003] Traditional explosion-proof lamps usually adopt a cable introduction method of pressure disc type, and the cable directly enters the interior of the lighting lamp through the introduction device for wiring. This meets the explosion-proof requirements to some extent, but in actual application, it exposes many deficiencies. First, because the lighting lamp lacks an independent wiring cavity, the construction personnel must disassemble the entire rear cover when wiring, which is not only cumbersome, but also greatly increases the operation difficulty in a bad site environment. Secondly, when the lighting lamp is leaking or damaged, the on-site workers need to open the lamp for troubleshooting or replacing the lamp, which often takes a long time and affects the work efficiency, and even may pose a potential threat to the operation safety. Furthermore, the connection firmness of the cable and the explosion-proof lamp needs to be improved, and there is a risk of falling off.
[0004] Therefore, an improved cable introduction structure is needed to improve the wiring convenience and fault handling efficiency of the explosion-proof lamp, so as to better adapt to the needs of special environments such as coal mines. SUMMARY
