Description

a linkage lock

technical field

The invention relates to a lock, especially a lock with two lock bodies.

Background technique

A kind of lockset in which two independent lock bodies are arranged in the same lockset panel has appeared on the market. The two lock bodies are respectively provided with lock cylinders, and the two locksets are used independently. The body is still in the locked state, so the door cannot be opened, and the door can only be opened by opening two locks at the same time. This lock has improved anti-theft performance and can better protect the safety of users; but this lock has the following defects: The door can only be opened when two locks are opened at the same time. In case of special circumstances such as fire, the person in the room needs to use the knob to open one of the locks first, and then use the handle inside the door to open the other lock. The body can open the door, so the opening of the door needs to be completed by two actions. At this critical moment, it will cause confusion and delay the opening time, thereby delaying the escape time and endangering people's lives.
