Abstract
The invention provides a sealing door lock device. A connecting block is arranged on the upper surface of the middle axis of one end of a door plate and is fixedly connected with the door plate and a lock body. The end of a hook-shaped shifting rod is located in a cavity of a spring bolt and is movably connected with the lock body through a rotary pin. A lock nose is fixedly arranged in the position, corresponding to the spring bolt, of the door body. A plug screw is fixed in the lock body through a locking screw, a spring is arranged in the lock body, one end of the spring is connected with the spring bolt, and the other end of the spring is connected with the plug screw. A hinge is arranged at the other end of the door plate and is connected with the door body and the door plate. When the hook-shaped shifting rod is shifted, the end of the hook-shaped shifting rod shifts the spring bolt to enable the spring bolt to beak away from the lock nose, and then a sealing door can be opened. An annular sealing strip is stuck to the periphery of an inner frame of the door body, when the door plate is locked, the door plate makes tight contact with the annular sealing strip, and a sealing effect is achieved. The sealing door lock device is simple in structure, reliable in connection, convenient to use and maintain and capable of easily achieving opening and closing of the sealing door.
