Description

Key and anti-theft lock

Technical Field

The invention relates to the technical field of locks, in particular to a key and an anti-theft lock.

Background

The lock is very popular in daily life of people, various locks used in families and units at present are mainly spring locks, and the spring locks have the advantages of simple structure, convenient manufacture and low price, and the existing spring locks control the rotation of a lock cylinder by utilizing a spring group which is arranged on the outer side of a lock cylinder rotor and can move up and down, and then toggle a lock tongue to open or close the lock. Because the structure of the existing cylinder lock is simpler, the cylinder group moves along the radial direction of the lock core during unlocking, the locking surface is an arc surface, the lock core needs to ensure the clearance between the outer side surface of the cylinder and the inner wall of the lock core sleeve due to rotation, so that the precision of the cylinder group is lower, lawless persons can easily adopt tools such as tinfoil to unlock technically, and because the cylinder group of the existing cylinder lock is arranged in a row along the length direction of a key, lawless persons can use a master key or a hooked tool to work when the lawless persons work, the lawless persons insert the key of the lock core, and the cylinders in the lock core are pushed into the lock core sleeve in sequence to easily unlock the lock; because the lock core of the existing cylinder lock rotates to drive the shifting shaft to open the lock body, the lock body is easy to open when being shifted, prized and drilled, an illegal molecule can easily insert a tool into a key hole to forcedly destroy the lock core to rotate, thereby opening the lock, and the anti-theft performance is poor; and because the thickness of the lockset is limited by the size of the tool to be halved, only three to six groups of marbles can be arranged, and the expansion range of each group of marbles is between two and four millimeters, the number of the marbles combined along the length direction of the key is limited to a certain extent, the key density of the lockset is low, the tooth-shaped repetition rate of the key is high, and the lockset is easy to open mutually, so that the personal and property safety of people is infringed.
