Abstract
The invention discloses a cutting-off type locking device used for locking an isolating mechanism at the safety position at ordinary times and unlocking the isolating mechanism in work. The cutting-off type locking device comprises a case, the isolating mechanism, a cutting-off mechanism, a body, an electrical actuator and a pressing screw. The isolating mechanism is installed in the case through a rotating shaft and can rotate around the rotating shaft. The cutting-off mechanism is fixed in the case and locks the isolating mechanism at the safety position through a cylindrical section protruding out of the bottom surface of the case. The body is fixed in a component of the case through the pressing screw, and the electrical actuator is fixed in a hole of the body through threads and does not make contact with the cutting-off mechanism. When the electrical actuator moves to make the cutting-off mechanism release restraint on the isolating mechanism, an isolating rotor can be pushed by a twist spring to rotate to the work position from the safety position. The cutting-off type locking device is simple in structure, small in size, high in safety, reliable in movement and suitable for security mechanisms of various pyrotechnic devices.
