[0007] Four groups of bolt holes are correspondingly arranged on the connecting surfaces of the main housing and the lamp housing.

[0008] An electrical component assembly is arranged in the main shell.

[0009] A wiring board is arranged in the main shell, the wiring board is arranged at the rear end inside the main shell, and the wiring board is provided with wiring terminals.

[0010] A sealing cylinder is arranged on the rear cover plate of the main shell, a metal plugging plate is movably arranged in the sealing cylinder, a clamping nut is threadedly connected to the sealing cylinder, and the end of the clamping nut is arranged in contact with the metal plugging plate.

[0011] A lamp tube fixing card is arranged in the lamp housing, and a xenon lamp assembly is connected to the lamp tube fixing card.

[0012] A transparent lampshade is arranged at the front end of the lamp housing, and a sealing gasket is arranged between the transparent lampshade and the lamp housing.

[0013] A bracket is connected to the outside of the lamp housing, and a mounting seat is fixedly arranged at the bottom of the bracket.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] By optimizing the structural design of the lamp housing and the main housing, and using the connection method of positioning pins and positioning through holes, the disassembly and assembly process between the lamp housing and the main housing meets the self-locking requirements. At the same time, the structure is simple and effective, which minimizes the weight of the entire lamp, meets the explosion-proof requirements, and is more convenient and efficient, greatly improving the maintenance efficiency and ease of use of the equipment. In order to ensure the explosion-proof performance of the equipment, this device also sets a sealing device at the connection between the rear end of the main housing and the transparent lampshade part at the front end of the lamp housing to prevent flammable gas or dust in the external environment from entering the interior of the equipment. The explosion-proof performance of the equipment is ensured, providing a safe and reliable solution for lighting needs in hazardous environments. BRIEF DESCRIPTION OF THE DRAWINGS
