[0005] To achieve the above objectives, this utility model provides an explosion-proof control box, including an outer shell module, an explosion-proof bracket module, and an internal electrical module. The outer shell module is mounted on the explosion-proof bracket module, and the internal electrical module is built into the outer shell module, wherein: The outer shell module includes a top plate, a bottom plate, a front plate, a rear plate, a first side plate, and a second side plate; The explosion-proof support module includes the first, second, third, fourth, fifth, sixth, seventh, eighth, ninth, tenth, eleventh, and twelfth frames, wherein: The first frame is installed between the top plate and the front plate, the second frame is installed between the top plate and the rear plate, the third frame is installed between the top plate and the first side plate, and the fourth frame is installed between the top plate and the second side plate; The fifth frame is installed between the front panel and the first side panel, the sixth frame is installed between the first side panel and the rear panel, the seventh frame is installed between the rear panel and the second side panel, and the eighth frame is installed between the second side panel and the front panel; The ninth frame is installed between the base plate and the front plate, the tenth frame is installed between the base plate and the rear plate, the eleventh frame is installed between the base plate and the first side plate, and the twelfth frame is installed between the base plate and the second side plate.

[0006] As a further preferred embodiment of the above technical solution, the first to twelfth frames are each provided with an integrally formed intermediate component, a first component, a second component, and a third component, wherein the first component, the second component, and the third component are distributed around the intermediate component, wherein: A first slot is formed between the first piece, the intermediate piece, and the third piece, and a second slot is formed between the second piece, the intermediate piece, and the third piece. The first slot and the second slot are used to insert corresponding boards (taking the first frame as an example, the first slot is used to insert one side of the top plate, and the second slot is used to insert one side of the front plate; the insertion method facilitates installation and disassembly).

[0007] As a further preferred technical solution of the above technical solution, the intermediate component, the first component, the second component and the third component are all provided with hollow holes (which have an explosion-proof function, can absorb energy when impacted, thereby protecting the internal electrical modules, and have good explosion-proof performance).
