Self-locking safety door

Abstract

The invention belongs to the technical field of safety doors, and particularly relates to a self-locking safety door. The self-locking safety door comprises a door frame, wherein a door body is arranged in the door frame; hinges are installed on one side of the door frame through bolts; the door body is rotatably connected with the door frame through the hinges; a loudspeaker and a cat eye are arranged on the door body; an unlocking mechanism is arranged on the door body; a first cavity and a second cavity are formed in the door body; an anti-theft mechanism is arranged in the first cavity; first lock holes are formed in the inner wall of the top and the inner wall of one side of the door frame; a sensing mechanism is arranged on the inner wall of the bottom of the first cavity; a gear boxis welded to the inner wall of one side of the second cavity; connecting rods are welded to the inner wall of the top and the inner wall of the bottom of the gear box; and fixing blocks are welded tothe ends, close to each other, of the connecting rods. According to the self-locking safety door, the distance between the self-locking safety door and the door frame is detected through a distance sensor, then a signal is sent to a controller, the controller starts a servo motor, and the automatic locking function is achieved.
