Description

technical field [0001] The invention relates to a lock cylinder, in particular to an anti-theft lock cylinder. Background technique [0002] A traditional mechanical lock generally consists of a lock case and a lock core which is arranged in the lock case and can rotate along the lock case. There are several pinholes arranged in rows along the axial direction of the lock core, and each pinhole is correspondingly equipped with a pintle. The lock shell is provided with sealing beads and pressure springs along its axial direction, and the gap between the pressure spring and the pintles is fixed. There is a card ball between them. In the original state, one end of the card ball is placed in the lock shell, and the other end is placed in the lock core. When the key is inserted into the lock core, the teeth on the key will make the pressing pins move axially. Move, when moving to a certain position, the card ball will be pushed out of the lock core by the marble, and move into t...

Problems solved by technology

There are several pinholes arranged in rows along the axial direction of the lock core, and each pinhole is correspondingly equipped with a pintle. The lock shell is provided with sealing beads and pressure springs along its axial direction, and the gap between the pressure spring and the pintles is fixed. There is a card ball between them. In the original state, one end of the card ball is placed in the lock shell, and the other end is placed in the lock core. When the key is inserted into the lock core, the teeth on the key will make the pressing pins move axially. Move, when moving to a certain position, the card ball will be pushed out of the lock core by the marble, and move into the lock case, prompting the lock case and the lock core to be unlocked; if this type of lock is inserted into the unlocking opening with a steel wire or other parts, the pin will be lifted up , and then it is easy to open the lock by choosing a key at random, which reduces the safety performance of the lock and is easy to be opened technically
