The alloy steel column 114 in the golden door 102, the alloy door frame 100 is provided with a plurality of first holes 115 coaxially aligned with the alloy steel column 114, the alloy door 102 is provided with a second hole 116 coaxially aligned with the alloy steel column 114, and one end of each of the alloy steel columns 114 is fixedly connected with a sliding block 117 located in the circular groove 103, and a spring 118 located in the circular groove 103 is fixedly connected between the sliding block 117 and the alloy door 102, so that the alloy steel column 114 can be driven to insert into the first hole 115 and the second hole 116 by rotating the cam 108, and multiple connections are made between the two alloy doors 102 and between the alloy door 102 and the alloy door frame 100, thereby greatly improving the explosion-proof effect.

[0025] A fixing plate 104 is fixedly connected in each of the circular grooves 103, and a motor 107 is fixedly connected to the front end surface of the fixing plate 104. The motor 107 is in power connection with the motor shaft 111, and the motor 107 can drive the cam 108 to rotate;

[0026] Each of the fixing blocks 105 is provided with a bearing 113, through which the rotating shaft 112 is rotatably connected to the fixing block 105, thereby improving firmness and enabling the alloy door 102 to be conveniently opened and closed;

[0027] The alloy door frame 100 is provided with a pouring groove 101, and is fixedly mounted on the wall through the pouring groove 101;

[0028] A handle 110 is fixedly connected to the rear end surface of the alloy door 102, and the handle 110 is pulled to open and close the alloy door 102;

[0030] Working principle:

[0031] First, the alloy door frame 100 is fixed on the wall by pouring concrete into the pouring groove 101. Then, when the alloy door 102 is closed, the motor 107 is controlled to start by the intelligent identification machine 109. The motor 107 drives the motor shaft 111 to rotate, and the motor shaft 111 drives the cam 108 to rotate. After the cam 108 rotates forty-five degrees, it pushes the sliding block 117 and the alloy steel column 114 to move, compresses the spring 118, and inserts the alloy steel column 114 into the first hole groove 115 and the second hole groove 116, so as to achieve multiple clamping between the alloy doors 102 and between the alloy door 102 and the alloy door frame 100, thereby improving the explosion-proof effect.

[0032] When the door needs to be opened, the motor 107 is started through the intelligent recognition machine 109. After the cam 108 is rotated back to its original position, the spring 118 drives the alloy steel column 114 to move out of the first hole groove 115 and the second hole groove 116. Then the handle 110 is pushed by hand to open the alloy door 102. The bearing 113 can reduce the friction between the alloy door 102 and the fixed block 105 when it rotates, making it easier to open the alloy door 102.
