Description

A separate shaft door lock structure

technical field

The utility model relates to the technical field of lock structures, in particular to a separated shaft type door lock structure.

Background technique

There are many types of door locks, and the requirements for door locks are different in various occasions. Ordinary families generally use anti-theft door locks, which are highly secure and relatively cheap; in some high-end places, security agencies will use combination locks and fingerprint locks. Very high and expensive; glass doors are used in many public places, so glass door locks will be more widely used.

After the two handles of present door locks are connected and fixed by a long square shaft mostly, by turning one of them in the two handles to rotate the square shaft, the dead bolt moves to open and lock the door. Although this connection method is simple in structure, due to the long length of the square shaft, the lock bolt will be rotated through the square shaft every time the door is opened or closed; The lateral pressure of the tongue is easy to deform, and there is a great potential safety hazard; and the door lock with the long-axis connection, if the interior is locked, the handle on the side of the room cannot be turned, and the door can only be opened by turning the locked structure. If people want to go from the room to the outside of the room, they must first open the anti-lock structure, then open the door, then use the anti-lock structure to lock again, and finally close the door; this process requires operating the anti-lock structure twice, which is extremely inconvenient.
