Problems solved by technology

[0002] Explosion-proof junction box is a special equipment used in various high-risk places. Compared with civilian junction boxes, it is a junction box with explosion-proof function after various explosion-proof transformations. It is made of aluminum alloy die-casting or stainless steel welding. The voltage 220V or 380V line is used to connect various electrical equipment and instruments for branching and wiring. The increased safety explosion-proof junction box is a common explosion-proof junction box. Most of the existing increased safety explosion-proof junction boxes are designed It is a square structure, and the box cover and the bottom of the box are fixedly connected by bolts. When it is necessary to carry out internal maintenance and other work, the disassembly and assembly work is more complicated, time-consuming and laborious. In addition, the existing structural design has a general waterproof and dustproof effect. There are certain defects. Therefore, it is of great significance to develop an increased safety explosion-proof junction box with stable structure, convenient disassembly and assembly, good dustproof and waterproof effect, and easy to carry.
