In addition to the basic anti-theft function, the fireproof interlayer 12 of the anti-theft door can also isolate flames and smoke in case of fire to prevent the spread of fire. The double-layer fireproof interlayer 12 is convenient for isolating the fire on both sides of the door panel 6 and protecting the locking mechanism 13 in the hollow groove.

[0026] As a technical optimization solution of the utility model, a fixing strip 8 is provided on the top of the door panel 6, a convex-shaped slide groove 9 is provided on the top of the fixing strip 8, a convex-shaped slider 10 is slidably connected in the slide groove 9, and a spring 11 is fixedly installed at one end of the slide groove 9 close to the hinge 2. The convex-shaped slider 10 can slide in the slide groove 9.

[0027] As a technical optimization solution of the utility model, the top of the embossed slider 10 is rotatably connected to the push rod 5, and the end of the push rod 5 is rotatably connected to the bottom of the fixed block 4. When the door panel 6 is opened, as the opening of the door panel 6 increases, the push rod 5 drives the embossed slider 10 to slide along the slide groove 9 in the direction of the spring 11 until the embossed slider 10 abuts against the spring 11 and compresses the spring 11. After a person passes, the door panel 6 is pulled to close the door, and the spring 11 loses its force and resets, pushing the embossed slider 10 to slide along the slide groove 9 in the direction away from the spring 11, that is, driving the push rod 5 to assist in closing the door panel 6.

[0028] As a technical optimization solution of the utility model, the locking mechanism 13 includes an electric telescopic rod 14, a connecting rod 15 and a sliding block 16.

[0031] When the door panel 6 is opened, the push rod 5 drives the convex slider 10 to slide along the slide groove 9 in the direction of the spring 11 until the convex slider 10 abuts against the spring 11 and compresses the spring 11. After the door panel 6 is opened to the maximum extent, the convex slider 10 stops sliding and the spring 11 is compressed to the limit. After the personnel pass through, the door panel 6 is pulled to close the door, and the spring 11 loses its force and resets, pushing the convex slider 10 to slide along the slide groove 9 in the direction away from the spring 11, that is, driving the push rod 5 to assist in closing the door panel 6, wherein the built-in fireproof interlayer 12 of the door panel 6 can effectively isolate fire and smoke in the event of a fire, thereby preventing the fire from spreading.

[0032] When an illegal criminal pries the combination lock 7, the combination lock 7 will receive multiple erroneous unlocking signals in succession, which can be determined as an abnormal unlocking state. At this time, the electric telescopic rod 14 works, and the telescopic end of the electric telescopic rod 14 extends, driving the connecting rod 15 and the sliding block 16 to slide along the direction of the guide rod 17. At this time, the locking steel bar 18 fixedly connected to the two sliding blocks 16 and the telescopic end of the electric telescopic rod 14 can be pushed out of the hollow groove and inserted into the locking groove 3 to achieve secondary locking of the door panel 6. Later, the telescopic end of the electric telescopic rod 14 can be retracted by entering the correct password or using a key to unlock the combination lock 7, driving the connecting rod 15 and the sliding block 16 to slide along the guide rod 17, so that the locking steel bar 18 is disengaged from the locking groove 3, and the normal use of the door panel 6 can be restored.
