Two-core mutual control rotary dislocation type mechanical lock

Abstract

The invention discloses a two-core mutual control rotary dislocation type mechanical lock. The two-core mutual control rotary dislocation type mechanical lock comprises a lock head body, an inner lock cylinder, an outer lock cylinder, a time delayer, a gate and a key; the outer lock cylinder is rotationally installed in the lock head body, and an outer locking mechanism capable of being decoded through the key is installed between the outer lock cylinder and the lock head body so that the outer lock cylinder can be prevented from rotating relative to the lock head body; the inner lock cylinder is rotationally installed in the outer lock cylinder, and an inner locking mechanism capable of being decoded through the key is installed between the inner lock cylinder and the outer lock cylinder so that the inner lock cylinder can be prevented from rotating relative to the outer lock cylinder; the outer lock cylinder controls continuous rotation of the inner lock cylinder; the inner lock cylinder controls the decoding condition of the outer lock cylinder through a control mechanism; before the inner lock cylinder rotates in place, the outer locking mechanism does not meet the decoding condition; and when the inner lock cylinder is decoded and rotates in place, the gate is closed, the time delayer stores energy, the outer locking mechanism can be decoded through the key, and the inner lock cylinder and the outer lock cylinder are driven by the key to rotate together so that unlocking can be achieved. The new concept and new method that the position difference is replaced with the time difference are adopted, and the two-core mutual control rotary dislocation type mechanical lock is one of the current most effective technological and violent unlocking preventing locks in the world.

Description

technical field [0001] The invention relates to a lock, in particular to a two-core mutual control rotation dislocation mechanical lock. Background technique [0002] The most widely used in the existing various locks is the tumbler lock, and there are many deficiencies in various tumbler locks in actual use, and it is easy to be opened by people with a special-purpose dial lock tool. The unlocking method is very simple. The person who unlocks the lock uses the unlocking wire hook to dial the pins in the lock body and the lock cylinder to the mating surface of the lock cylinder and the lock body one by one, and then turn the lock cylinder to open the lock; After the key is inserted into the lock hole and shaken, the traces of the marbles are printed on the tin foil so that all the marbles fall on the mating surface of the lock cylinder and the lock head body, and then turn the lock cylinder to unlock; you can also use a toothed tool to hit or dial back and forth The marbles...

Problems solved by technology

In order to increase safety, the prior art adopts a double lock core structure, such as disclosed in patent publication numbers CN203925006U, CN203603627U and CN203769466U, but in these existing double lock core structures, their two lock cores are arranged side by side , usually two keys are used to unlock the lock, which also has the disadvantages of being easily unlocked by technology or violence
