Abstract
An electric control door lock includes an inner operational device, an outer operational device, and a latch bolt operably connected to the inner and outer operational devices. A rotating shaft is rotatably supported in an activation member and includes a driving threaded in threading connection with a driving spring. When the rotating shaft is driven by a motor to rotate, the driving spring moves along a longitudinal axis to actuate the activation member. Movement of the activation member is used to control operation of the outer operational device, thereby permitting or not permitting movement of the latch bolt to the unlatching position.
