Abstract: An enhanced door lock is capable of being locked from an inner side of a doorplate. At the outer lock portion, a ring seat and a C ring clamp two sides of the outer plate of the doorplate so as to enhance the structure of the doorplate to prevent the door lock from being pulled out. The inner cover is installed with a positioning hole. One side of a top of the control knob is drilled with a stud receiving groove. A positioning pin is placed in a stud receiving groove. The outer sleeve and the stud of the positioning pin are coupled with the stud receiving groove; then the bead resisting against the spring exactly pushes the positioning groove of the stud to resist against a positioning groove. By this structure, the lock is locked from the inner side of the doorplate.
