Abstract
The utility model relates to an explosion-proof plugging connection device and belongs to the explosion-proof electric appliance connection device filed. The explosion-proof plugging connection device is composed of a plug and a socket. The plug and the socket are in plugging matching with each other so that the explosion-proof plugging connection device can be used. According to the plug, the bottom of a cylindrical body I is fixedly connected with a circular stage; more than two plugging pins are uniformly distributed on the circular stage; and the tail of the cylindrical body I is in threaded connection with a cylinder-shaped shell I. According to the socket, a cylinder insulating piece is fixed inside a cylindrical body II; pin hole pieces which are in one-to-one correspondence with the plugging pins are arranged in the cylinder insulating piece; the tail end of the cylindrical body II is in threaded connection with a cylinder-shaped shell II; more than two clamping hooks are evenly distributed on the periphery of the cylindrical body I; and locking clamping devices which are used in cooperation with the clamping hooks are arranged on the periphery of the cylindrical body II. The explosion-proof plugging connection device of the utility model has the advantages of reasonable structural design and favorable explosion-proof effect. Fast plugging and pulling out of the explosion-proof plugging connection device can be realized, and therefore, time can be saved, and efficiency can be improved. The tail ends of the plug and the socket are respectively provided with a cable fixing piece, and therefore, falling off which is caused by pulling which is further caused by misoperation of lines and wiring ends can be avoided.
