PUSH-PULL DOOR LOCK HAVING ANTI-PANIC FUNCTION
The present inventive concept relates to a push-pull door lock having an anti-panic function, the push-pull door lock comprising: a door locking device which is provided inside a door and opens/closes the door; a handle device comprising bodies fixedly provided on the indoor side and the outdoor side of the door, and handles which are respectively provided on the bodies to be pushed or pulled; and a locking means which is provided in each of the bodies of the handle device and locks the operation of the handle to lock the door, wherein the locking means comprises: a key knob assembly which is rotatably provided in the indoor side body; a key assembly which is rotatably provided in the outdoor side body and is connected to the key knob assembly to be rotated along with the key knob assembly; and a stopper which is connected to the key assembly, is rotated along with the key assembly, and locks the operation of the handle. The locking means includes guide plates which are provided on the indoor side and outdoor side bodies and are moved up and down on the bodies by push and pull operations of the indoor side and outdoor side handles. The outdoor side guide plate has a through-hole through which the stopper passes to be rotatable and to which the stopper is coupled after being rotated so as to stop the moving-up/down operation of the guide plate during locking of the locking means. The key knob assembly passes through the indoor side guide plate to be rotatable, and is rotated when the guide plates are moved up and down.
