A double core mutual control axial displacement mechanical lock

Abstract

The invention discloses a double-core mutual control axial displacement mechanical lock, which comprises a lock head body, a lock core, a gate and a key; the lock core is split into an upper core body and a lower core body; The upper and lower locking mechanisms are installed between the upper and lower cores and the lock body, and the key is provided with upper and lower key grooves to decode the upper and lower locking mechanisms respectively; the lower core is also equipped with To control the control mechanism of the upper locking mechanism, the upper locking mechanism does not have the decoding conditions before the lower core moves in place in the axial direction; when the key first decodes the lower locking mechanism, then use the key to push the lower core to move backward in the axial direction When it is in place, the gate is closed, and the control mechanism releases the control of the upper locking mechanism at the same time, so that the key can decode the upper locking mechanism, and the upper and lower cores rotate together under the drive of the key to unlock. The present invention adopts a new idea and a new method of exchanging position difference for time difference, and is one of the most effective prevention techniques and locksets for violent unlocking in the world at present.

Description

Technical field [0001] The invention relates to a lock, in particular to a dual-core mutual control axial displacement mechanical lock. Background technique [0002] The most widely used of the existing various locks is the pin lock, and various pin locks have many shortcomings in actual use, and they are easy to be opened by a dedicated lock tool. Due to the various defects of traditional marble locks, its security is greatly reduced, and it provides convenience for the thief, resulting in frequent thefts. In order to increase safety, the prior art proposes a double lock core structure, such as disclosed in patent publication numbers CN203925006U, CN203603627U, and CN203769466U. However, in the 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. The prior art also proposes a lock with an upper and lower pin struc...

Problems solved by technology

In order to increase safety, the prior art proposes 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, and there are also the disadvantages of being easily unlocked by technology or violently.

The prior art also proposes a lockset with upper and lower tumbler structures, as disclosed in the patent publication number CN203514995U. It is equipped with two rows of tumbler mechanisms in a lock cylinder. After the key is inserted, the key is controlled, and the lock is pushed forward and pulled back. Unlocking, this kind of lock also has the disadvantage of being easy to be unlocked by technology or violently
