[0002] An explosion-proof control box is a specially designed enclosure for electrical equipment in flammable and explosive environments. It is mainly used to protect internal electrical components from the influence of harsh external environments and to prevent explosions caused by electrical sparks or high temperatures.

[0003] Currently, explosion-proof control boxes are usually equipped with interlocking mechanisms, which can control the internal circuit breaker to cut off power. However, these mechanisms require fully manual operation, and forgetting to operate them can easily lead to major accidents. Furthermore, they have low safety and are not suitable for current use. Therefore, we propose an explosion-proof control box with an interlocking mechanism to solve the above problems. Utility Model Content
