Rear unlocking type lock with double mutually-controlled cylinders
The invention discloses a rear unlocking type lock with double mutually-controlled cylinders. The rear unlocking type lock with the double mutually-controlled cylinders comprises a lock head body, the front lock cylinder, the rear lock cylinder, a key, a delay mechanism and gates. The front lock cylinder and the rear lock cylinder are arranged in the lock head body rotatably, and a front locking mechanism and a rear locking mechanism capable of being decoded through the key are arranged between the front lock cylinder and the lock head body and between the rear lock cylinder and the lock head body respectively, so that rotation of the front lock cylinder and the rear lock cylinder relative to the lock head body is limited. The front lock cylinder controls the rotation of the rear lock cylinder which controls the decoding condition of the front lock cylinder through a control mechanism. The front locking mechanism does not have the decoding condition before the rear lock cylinder is moved in place. When the key decodes the rear locking mechanism and pushes the rear lock cylinder to move backwards in place in the axial direction, the gates are closed at the time, and the delay mechanism is started; the control mechanism decontrols the front locking mechanism so that the key can decode the front locking mechanism; the front lock cylinder and the rear lock cylinder are driven by the key to rotate together, and accordingly unlocking is achieved; on the contrary, the delay mechanism locks the lock. According to the rear unlocking type lock with the double mutually-controlled cylinders, a novel idea and method of replacing of the time difference by the position difference are used, and the lock is one of the most effective locks capable of preventing technological and violence unlocking at present in the world.
