Lock key with changeable structure

Abstract

The invention discloses a lock key with changeable structure. The lock key comprises a lock casing (15), a lock core (6), an inner lock bolt (9), a rotation disk (7), a bolt, a ball hole (11) and a ball and a spring (12) thereof. The lock key is characterized in that a primary marble (4) and the marble hole on the lock core (6) are connected in series by a split-type marble sleeve (3) via a sleeve fixing pin (2) and are then sheathed and positioned with a linkage skidproof rod; and a skidproof ring with cutting is fixed on the lock casing close to end of the skidproof rod behind the rotation disk. The lock key of the invention has high secrecy, flexible changeable lock key structure, low cost and convenient process; a single key can open a plurality of locks of the same size and the same type, thereby saving problems of bringing a great number of keys.

Description

technical field [0001] The invention relates to a lock, especially a key whose structure can be changed according to needs. Background technique [0002] Traditional locks are all made up of fixed-structure locks and corresponding keys, that is, one key can open one lock, so many people often need to carry a large bunch of keys with them. If the keys are lost, they can only be destroyed by destroying them. When the lock is opened, the key cannot be used if the lock is broken. At the same time, the key coupling rate of the traditional lock is high and the safety performance is low. To solve this problem, people have developed a series of new locks such as smart locks and electronic remote control locks. These locks It must have electricity to operate normally, and it is necessary to carry a separate remote control or identification card. It is easier for people who understand its structure to develop a universal decoder. Vehicles are often lost, doors are opened and other the...

[0002]Traditional locks are all made up of fixed-structure locks and corresponding keys, that is, one key opens one lock, so many people often It is necessary to carry a large bunch of keys with you. If the key is lost, it can only be opened by destroying the lock. If the lock is broken, the key cannot be used. At the same time, the key coupling rate of the traditional lock is high and the safety performance is low. To solve this problem, people develop A series of new locks such as smart locks and electronic remote control locks have been released. These locks must be powered to operate normally, and they also need to carry a separate remote control or identification card. It is easier for those who understand their structure to develop a universal decoder. In the event of a vehicle being lost, the door being opened, etc., the newly developed fingerprint recognition locks in recent years are relatively safe and do not need to carry keys, but their operation is still dependent on electricity, and the production cost is high. use, difficult to promote
