[0003] The patent name is "An explosion-proof door" with the publication number "CN111877946B". The door frame and the door body in the public document rotate by hinges. When the door body and the door frame are installed, the staff needs to first connect one side of the hinge with the door frame by bolts, then install the door body into the door frame, and then overlap the socket on the other side of the hinge with the threaded hole at the door body, and then insert the bolt into the socket on the other side of the hinge and install it into the threaded hole of the door body, so as to achieve the connection between the door body and the hinge. The disadvantage of this installation is that because the door body of the explosion-proof door is very heavy, when the bolt connects the hinge to the door body, it is necessary to always keep the consistency of the socket of the hinge and the threaded hole of the door body overlapping each other. Due to the weight of the door body, the staff cannot accurately overlap the threaded hole at the vertically placed door body with the socket at the hinge, resulting in the need for continuous debugging by the staff. This operation method is time-consuming and labor-intensive, affecting the progress of the installation of the door frame and the door body. Based on this, the utility model designs an explosion-proof door to solve the above problems. Utility Model Content

[0026] The staff first puts the support plate 2 into the frame 1, and after the insertion rod 501 and the limiting hole 3 are overlapped with each other, the staff then reverses the rotating rod 401, and the rotating rod 401 drives the circular plate 402 to push the connecting rod 502 to link the insertion rod 501 to be inserted into the limiting hole 3, thereby realizing the quick connection between the support plate 2 and the frame 1. When the outer side surface of the insertion rod 501 contacts the limiting hole 3, at this time, the positioning hole 503 and the mounting hole 504 overlap with each other, and the staff then inserts the limiting pin 506 into the overlapping mounting hole 504 and the positioning hole 503, and then locks the state of the insertion rod 501 in the limiting hole 3. The staff then pushes the support plate 2, and the support plate 2 drives the insertion rod 501 to rotate with the center of the limiting hole 3 as the center of the circle, thereby opening or closing the support plate 2. When the support plate 2 needs to be disassembled, only the above-mentioned operation method needs to be reversed. Example 2
