Background

Currently door mounted locks are generally comprised of a lock body, a strike assembly mounted to the lock body, an auxiliary strike assembly, and a strike assembly. The auxiliary bolt of the lock in the market is an independent structure part, plays a role of insurance indoors, and needs to be independently opened when being opened indoors, which is quite inconvenient.

The prior patent with the publication number of CN206530156U discloses a mechanical lock capable of being opened and closed quickly. Through the internal mechanical linkage mechanism, the mechanical lock can be opened when the handle rotates downwards. When the mechanical lock needs to be closed, the handle is rotated upwards, and the square core drives the shifting piece to rotate, so that the shifting piece shifts the auxiliary lock tongue to be closed, and the locking operation is more convenient.

The prior art solution described above has the following drawbacks: the square core of the connecting handle is positioned in the lock shell and close to the lower end. The installation height of the lock tongue is as close to the middle part of the door plate as possible, and the height of the square core is close to the elbow of a normal person, namely, the position 1.1m away from the ground. Therefore, when the device is used for a lower door, if the device is adapted to the height of the elbow of a person, the position of the lock tongue is located at an upper position in the middle of the door plate, and the position is not the most suitable installation height of the lock tongue.
