Push-pull-push door-lock equipment is provided to close a door along the closing direction, and to open the door by pulling the door along the opening direction or by pushing the door along the closing direction. A latch is hinged to a door and is inserted into a lock device, and closes the door. The lock device comprises a grip, a grip panel(230) and a push guide path. The grip enables the latch to be hooked to the latch by being guided along a pull guide path. The grip panel prevents the deviation of the grip. The push guide path separates the latch from the grip when the door is pushed.
