Safe seal lock
The invention relates to a safe seal lock, comprising a lock body and a lock rod. One end of the lock rod is fixedly connected with the lock body. A side of the lock body is provided with a cylindrical longitudinal hole extending inward. The internal diameter of the longitudinal hole is larger than the external diameter of the lock rod. The bottom opening of the longitudinal hole is a reverse trumpet opening. The bottom opening contracts inwards. The left side of the lock body is a hollow cavity. The cavity is internally provided with metal glue. The right lower side of the longitudinal hole is a hollow structure. The hollow structure is internally provided with a safety device. A drop bar can slide along a horizontal direction. A spring is arranged on a direction horizontal to the drop bar. The spring and the drop bar are separated by a baffle. The lower part of the baffle is connected with a hydraulic rod. The baffle can move up and down with the hydraulic rod. The upper part of the hydraulic rod is also fixedly connected with a bearing plate. The bearing plate is right below the longitudinal hole. The bearing plate is provided with a pressure sensor. The pressure sensor is electrically connected with a PLC. The PLC controls extension of the hydraulic rod. The seal lock is made safer.
