Double-cylinder mutual-control axial displacement mechanical lock
The invention discloses a double-cylinder mutual-control axial displacement mechanical lock. The double-cylinder mutual-control axial displacement mechanical lock comprises a lock head body, a lock cylinder, a gate and a key, wherein the lock cylinder is divided into an upper cylinder body and a lower cylinder body; the lower cylinder body can shift in the axial direction in the lock head body; upper and lower locking mechanisms are disposed between the upper and lower cylinder bodies and the lock head body respectively; the key is provided with upper and lower face key grooves which are used for decoding the upper and lower locking mechanisms respectively; the lower cylinder body is further provided with a control mechanism used for controlling the upper locking mechanism; before the lower cylinder body moves in place in the axial direction, the upper locking mechanism does not meet the decoding condition; when the key decodes the lower locking mechanism firstly and then the key is used for pushing the lower cylinder body to move in place backwards in the axial direction, the gate is closed, at the same time, the control mechanism decontrols the upper locking mechanism so that the key can decode the upper locking mechanism, and the upper and lower cylinder bodies are driven by the key to rotate together so as to achieve unlocking. A novel idea and a novel method which exchange time difference with position difference are adopted, and the double-cylinder mutual-control axial displacement mechanical lock is one of locks which are the most effective and capable of preventing technical and violent unlocking at present in the world.
