[0046] By designing the surface of the locking rod 504 and the surface of the auxiliary rod 603 into an arc shape, when the anti-theft door is closed, the impact force generated by the collision between the door body 1 and the door frame will push the locking rod 504 and the auxiliary rod 603 to move through the arc-shaped surface. After the door body 1 is completely closed, the locking rod 504 and the auxiliary rod 603 will be reset under the action of the spring and stuck inside the door frame, thereby achieving an automatic locking effect and improving the anti-theft effect of the anti-theft door.

[0047] The locking rod 504 and the auxiliary rod 603 are respectively installed on the side, top and bottom of the door body 1, and the locking rod 504 and the auxiliary rod 603 can both lock the anti-theft door, thereby dispersing the locking points of the anti-theft door. When external force acts on the door, the dispersed locking points can evenly disperse the force to various parts of the door, avoiding the concentration of force on a few points, making it difficult for the prying person to open the door by concentrating force on a certain locking point, greatly increasing the door's anti-theft ability, and solving the problem of the existing anti-theft door with concentrated lock points, resulting in a lack of effective protection for other parts of the anti-theft door.

[0048] When closing the door, the auxiliary rod 603 pushes the slide plate 602 to move under the action of the door frame and the door body 1 until the door frame and the door body 1 are completely fitted together. At this time, the spring three 604 will push the slide plate 602 to reset and push the auxiliary rod 603 to get stuck inside the door frame. When opening the door, the gear 501 is rotated, and the gear 501 drives the slide plate 602 to move through the rack two 601, so that the auxiliary rod 603 moves to the inside of the door body 1, and the door can be opened at this time.
