The push rod lock structure of the fire door is firm, preventing outsiders from entering the interior without permission, while allowing insiders to go out in an emergency. The lock can be opened by pressing the push bar at a certain part of the body. It is often used on the fire door of the fire passage to realize the emergency escape function in case of fire. It is now used in densely populated places.
