Power-off uncovering protection device for explosion-proof electric appliance

Abstract

The utility model discloses an explosion-proof electric appliance power-off uncovering protection device which comprises a shell cover installed on the front side of an explosion-proof shell, a controller and a relay are arranged in the explosion-proof shell, the shell cover is detachably installed on the front side of the explosion-proof shell through a screw, a travel switch is fixedly installed on the top of an inner cavity of the explosion-proof shell, and the travel switch is detachably installed on the inner cavity of the explosion-proof shell. The top of an inner cavity of the anti-explosion shell is slidably connected with an extrusion plate, the surface of the extrusion plate makes contact with the travel switch, a clamping block is installed in the inner cavity of the anti-explosion shell, and an inner cavity of the clamping block is slidably connected with a connecting rod extending to the outer side. According to the utility model, the pressing rod and the clamping block are unlocked by pressing the pressing rod, so that the clamping block and the extrusion plate are driven to slide forwards, the extrusion plate is not contacted with a detection head on the travel switch any more, a relay in the explosion-proof shell is controlled to carry out power-off operation, and the purposes of rapidly cutting off power and reducing accidents can be achieved.
