ABSTRACT:
A door lock transmission mechanism is provided on the first surface of a door for transmitting movement to a door lock provided on the second surface of the door opposite to the first surface. The door lock transmission mechanism includes a lock casing unit, an actuation mechanism, and a locking mechanism. The actuation mechanism includes a traction member having a traction portion for driving a locking seat of a core unit of the locking mechanism, wherein the locking seat can rotate freely when the locking mechanism is locked, such that an actuation member of the actuation mechanism can be pressed down by force and keeps the locking state of the door lock, and thus the parts of the door lock transmission mechanism can be protected from being damaged.
