Description

technical field [0001] The invention relates to a lock core with a combination lock bead of bead pieces. Background technique [0002] Lock is an item that people cannot leave in daily life. Human beings have been using locks to store important items since ancient times, so that their property will not be stolen by others. The core anti-theft part of the lock is the lock cylinder structure. The performance of the lock cylinder structure is excellent. Inferiority directly affects the anti-theft performance of the entire lockset. In the existing lockset, the lock cylinder structure generally includes a lock cylinder and a key that are mutually adapted. The lock cylinder is provided with a keyhole into which a key can be inserted to open or lock the lock cylinder. The existing lock core structure generally only uses a row of marbles or password chips arranged in the lock cylinder and a marble groove arranged on the key as the locking structure. The design of the locking struct...

AI Technical Summary

Problems solved by technology

The existing lock cylinder structure generally only uses a row of marbles or password chips arranged in the lock cylinder and a marble groove arranged on the key as the locking structure. The design of the locking structure is too simple like this, and ordinary unlocking tools can Easy technical unlocking, poor anti-theft function, not stable and reliable to use, low safety performance, and poor security effect

Secondly, due to the small number of marbles or cipher chips, the small number of codes, and the high mutual opening rate and repetition rate of keys, it is easy for one key to fit multiple locks or multiple keys to fit a lock. The structure is too simple, easy to be imitated, and the anti-theft performance of the lock is low

In addition, some lock cylinders use a combination of two bead pieces to increase the number of codes. The combination grooves of the lock cylinder have a large width and a large number, resulting in a low structural strength of the lock cylinder, which is easy to be broken
