It has high security, is not easy to crack, and has good anti-smashing and anti-collision performance.

Description

technical field [0001] The present application relates to the technical field of door locks, in particular to a door lock. Background technique [0002] At present, there are many manufacturers of door locks on the market, some are engaged in mechanical locks, and some are engaged in smart locks developed on the basis of mechanical locks. However, whether the existing door locks are mechanical locks or smart locks, when violent damage occurs, such as knocking or hitting with heavy objects or sharp objects, the door locks are easily damaged, resulting in unnecessary losses. , especially in some factory warehouses where valuables are housed, once the door locks are damaged, the loss will be immeasurable. In addition, the existing mechanical locks can be divided into key-type and rotary combination locks. Among them, the key-type mechanical lock is easy to crack according to the internal structure of the keyhole, while the rotary combination lock is easy to crack according to ...

AI Technical Summary

Problems solved by technology

However, no matter the existing door locks are mechanical locks or smart locks, when they encounter violent damage, such as knocking or hitting with heavy or sharp objects, the door locks are easily damaged, resulting in unnecessary losses. , especially in some factory warehouses with valuables, once the door lock is damaged, the loss is immeasurable

In addition, the existing mechanical locks can be divided into key-type and rotary combination locks. Among them, the key-type mechanical lock is easy to crack according to the internal structure of the keyhole, while the rotary combination lock is easy to crack according to the sound generated when turning. , thus, the overall anti-theft performance of the mechanical lock is poor
