DETAILED DESCRIPTION OF THE INVENTION

[0016] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings, wherein the same parts are represented by the same reference numerals.

[0017] It should be noted that the words "front", "rear", "left", "right", "up" and "down" used in the following description refer to directions in the drawings, and the words "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively.

[0018] In order to make the contents of the present invention more clearly understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0019] like Figures 1 to 4 As shown, it includes two mounting plates 1, and a second fireproof layer 12 and a heat insulation layer 13 are fixedly connected inside the mounting plates 1, and the heat insulation layer 13 is located inside the mounting plates 1, and the second fireproof layer 12 is installed on the opposite side of the heat insulation layer 13 in the two mounting plates 1. By arranging the second fireproof layer 12 and the heat insulation layer 13 in the two mounting plates 1, it can play a role of heat insulation and fire prevention in case of fire, and movable grooves 2 are opened at both ends of the opposite sides of the two mounting plates 1, and a buffer structure 3 is arranged in the movable groove 2, and a buffer spring 4 is fixedly connected between the buffer structures 3, and a buffer plate 5 is fixedly connected to the buffer spring 4 and the side of the buffer structure 3 away from the mounting plates 1. The buffer plate 5 is used in conjunction with the buffer structure 3 and the buffer spring 4, so that when the protective door as a whole receives a significant impact force, a corresponding damper is arranged inside the buffer spring 4, which can better alleviate and weaken the force, and minimize the impact of the explosion on the protective door as a whole;

[0020] The buffer structure 3 includes a guide rod 301, which is fixedly connected to the movable groove 2. A movable block 302 is sleeved on the outside of the guide rod 301. The movable block 302 slides in the movable groove 2. A connecting rod 303 is provided between the movable block 302 and the buffer plate 5. One end of the connecting rod 303 is rotatably connected to the top of the movable block 302. The connecting rod 303 is driven to move along the guide rod 301 by the movable block 302. The other end is rotatably connected to the buffer plate 5. The ends of the connecting rod 303 close to the buffer plate 5 are close to each other. A spring 304 is fixedly connected between the end of the movable groove 2 away from the connecting rod 303 and the movable block 302. The spring 304 is sleeved on the outside of the guide rod 301. The buffer plate 5 is supported by the connecting rod 303 in cooperation with the spring 304, and the impact force is reduced by the spring 304 when it is hit.

[0021] The four corners of the mounting plate 1 and the buffer plate 5 are each provided with a groove 6. A reinforcing plate 7 is provided between the two mounting plates 1. The two sides of the reinforcing plate 7 are fixedly connected between the two mounting plates 1. By providing the reinforcing plate, there is a moving gap between the two mountings, which can reduce the overall weight of the explosion-proof door. Four corners of the reinforcing plate 7 are fixedly connected with support plates 9. One end of the support plate 9 away from the reinforcing plate 7 is fixedly connected with angle irons 10. The support plate 9 is connected between the reinforcing plate 7 and the angle iron 10. The four corners of the overall explosion-proof door are reinforced by the angle irons 10. By clamping the angle irons 10 into the grooves 6, it is possible to avoid affecting the installation of the explosion-proof door.

[0022] On the four sides of the opposite sides of the two mounting plates 1, there are fixedly connected support frames 8. The space between the two mounting plates 1 is enclosed by the support frames 8. At the same time, the space between the two mounting plates 1 is a hollow structure, which can reduce the overall weight of the explosion-proof door.
