Problems solved by technology
[0004] The above scheme has the advantages of easy operation, excellent sealing performance and stronger compatibility; however, there are still some defects in the above scheme, such as: 1. When the explosion-proof box is used in the environment of mining areas and dust working conditions, explosive gas passes through the gap Entering the inside of the control box, it is very easy to cause an explosion. Therefore, most of the existing explosion-proof boxes are sealed, and the strong sealing is easy to cause the internal heat of the explosion-proof box to be unable to dissipate quickly, thereby affecting the normal operation of the internal electrical components; 2. The existing The explosion-proof box body is mostly made of aluminum alloy material. When a fire occurs, due to the poor fire resistance of aluminum alloy, it is easy to affect the normal operation of the electrical components inside the explosion-proof box; 3. The box body and the box cover in the above scheme pass through Setting multiple limit slots and limit inserts can realize quick disassembly and assembly, but when the explosion-proof box is set at the corner or the distance between the explosion-proof box and the roof is too close, it is easy to cause the limit inserts to be unable to be taken out, thus affecting the explosion-proof box normal use
