| titleOfInvention | A coal mine electrical explosion-proof box |
| abstract | The utility model discloses an electric explosion-proof box for coal mines, which comprises a box body, a cover groove, a built-in cavity and a guide groove. A protection mechanism is movably connected to the outer side of the box body, and a connection frame, a telescopic and retractable mechanism are sequentially arranged inside the protection mechanism. A rod, a buffer spring, a first protective plate and a second protective plate, the top and both sides of the connecting frame are fixedly connected with telescopic rods, and the inside of the box body is provided with a built-in cavity. The utility model moves the limit rods to one end of the cover groove respectively, and then puts the cover body into the inside of the cover groove, and then releases the limit rod. Internal sliding, the slider drives the limit rod to move to one side of the cover body through the connecting block, so that the limit rod and the cover body are clamped to each other, so that the cover body and the box body are fixed to each other, and the function of the mechanism for easy maintenance is realized. Thus, the convenience of the coal mine electrical explosion-proof box in use is improved. |
