A simple indoor door lock consists of a lock body mechanism, a lock cylinder mechanism, a slider mechanism, a lock cylinder panel and a slider panel. A plurality of parts and mechanisms are reduced in the lock body, the dimensions of a base and an upper cover of the lock body are reduced by one third compared with those of the common lock body, and fewer holes are formed in the base and the upper cover than the common lock body. Processes are reduced, the raw material cost is greatly reduced, and manual processing fees are reduced. Meanwhile, the length of the lock cylinder is only 20-24 millimeters, only four marbles are arranged, and the housing of the lock cylinder is greatly shortened. Besides, the one-piece lock cylinder is eliminated, the panel square steel part is controlled through the slider, and a back locking function can be realized. As outdoor key control is separated from an indoor back locking button, after back locking is carried out indoors, the door cannot be opened even if the door lock is opened with a key outdoors. After the whole door lock is modified, the raw materials are greatly saved, and the production cost of the door lock is also greatly reduced.
