A simple indoor door lock

Abstract

A simple indoor door lock. Specifically include: the door lock is composed of a lock body mechanism, a lock cylinder mechanism, a slider mechanism, a lock cylinder panel, and a slider panel. The lock body in the present invention reduces many components and mechanisms, the base and upper cover of the lock body are one-third smaller than ordinary lock bodies, and the holes opened by the base and upper cover are also much less than ordinary lock bodies. a lot of. Not only has the process been reduced, but the cost of raw materials has also been greatly reduced, and the cost of manual processing has also been reduced. Simultaneously, its length of the lock core among the present invention is only 20~24 millimeters, and the set marbles have only 4, and the lock core shell is also greatly shortened. In addition, the present invention omits the one-piece lock cylinder, and the anti-lock function can be realized through the square steel part of the slider control panel. Because the key control outside the door is separated from the anti-lock knob inside the door, after the door is locked inside, even if the key outside the door is turned on, the door cannot be entered. After the integral door lock of the present invention is transformed, raw materials are greatly saved, and the production cost of the door lock is greatly reduced.
