[0022] The following is combined with Figure 1-2 This application is described in further detail.
[0023] The present application embodiment discloses an impact-resistant civil air defense door leaf frame structure, referring to Figure 1 and Figure 2 An impact-resistant civil air defense door leaf frame structure includes a door leaf body 1, a movable plate 2 and a buffer assembly 3. The door leaf body 1 is a conventional steel civil air defense door leaf, and a mounting groove 11 is provided on the side of the door leaf body 1 facing the outside of the civil air defense facility room. The mounting groove 11 is a rectangular groove body, the movable plate 2 is a rectangular plate body, and the size of the movable plate 2 corresponds to the size of the mounting groove 11. The movable plate 2 is slidably mounted on the door leaf body 1 and is located in the mounting groove 11, and the movable plate 2 is located on the opening side of the mounting groove 11. The buffer assembly 3 is arranged on the door leaf body 1 and is located in the mounting groove 11. The buffer assembly 3 is connected to the movable plate 2. When the movable plate 2 is subjected to an external impact force, the impact force is transmitted to the buffer assembly 3 through the movable plate 2, and then transmitted to the door leaf body 1 through the buffer assembly 3. In this process, the buffer assembly 3 is used to reduce the impact force transmitted from the movable plate 2 to the door leaf body 1.
[0024] By arranging a buffer component 3 and a movable plate 2 on the door leaf body 1, when the civil air defense door is hit or impacted, the movable plate 2 is first subjected to the impact force, and the impact force is then transmitted to the buffer component 3 and the door leaf body 1 in sequence. In this process, the impact force transmitted from the movable plate 2 to the door leaf body 1 is reduced by the buffer component 3, thereby reducing the impact received by the door leaf body 1, thereby improving the impact resistance of the civil air defense door and improving the problem that the civil air defense door is easily deformed, bent or even broken when impacted.
[0025] Reference Figure 1 and Figure 2 A plurality of sliders 21 are arranged on the edges of the movable plate 2, and a plurality of slide grooves 12 are arranged on the side walls of the mounting groove 11. The length direction of the slide groove 12 is perpendicular to the plane of the door leaf body 1. The plurality of slide grooves 12 correspond to the plurality of sliders 21 one by one, and the sliders 21 are slidably arranged in the slide grooves 12. Furthermore, the slide groove 12 is closed at one end close to the opening of the mounting groove 11, so that the movable plate 2 can only move in the mounting groove 11 and cannot leave the range of the door leaf body 1.
[0026] Reference Figure 1 and Figure 2The buffer assembly 3 includes a buffer plate 31, an airbag 32 and an energy absorbing member. The buffer plate 31 is a rectangular plate body. The shape and size of the buffer plate 31 are the same as those of the movable plate 2. The buffer plate 31 is slidably arranged on the door leaf body 1 and is located in the mounting groove 11, and the buffer plate 31 is located between the movable plate 2 and the door leaf body 1. A plurality of guide blocks 33 are arranged on the edges around the buffer plate 31. The plurality of guide blocks 33 correspond to the plurality of slide grooves 12 on the side wall of the mounting groove 11, respectively, and the guide blocks 33 are slidably arranged in the slide grooves 12. The airbag 32 is arranged on the buffer plate 31, and the airbag 32 is located on the side of the buffer plate 31 facing the movable plate 2. The energy absorbing member is arranged on the bottom wall of the mounting groove 11 and connected to the buffer plate 31. The energy absorbing member is used to absorb the impact force transmitted from the buffer plate 31 to the door leaf body 1.
[0027] When the movable plate 2 is hit or impacted, the movable plate 2 moves toward the door leaf body 1 and compresses the airbag 32. The air in the airbag 32 is compressed by the impact force, and the airbag 32 plays a preliminary role in buffering and absorbing the impact force. Then, the impact force drives the airbag 32, the movable plate 2 and the buffer plate 31 to continue to move toward the door leaf body 1. At this time, the energy-absorbing part between the buffer plate 31 and the door leaf body 1 further absorbs and buffers the impact force, thereby enhancing the energy-absorbing and buffering effect of the door leaf body 1 and improving the impact resistance of the door leaf body 1.
[0028] Reference Figure 1 and Figure 2 , the buffer plate 31 is staggeredly provided with multiple spacers 311 on one side of the movable plate 2, and the multiple spacers 311 separate multiple accommodation spaces on the buffer plate 31, and multiple airbags 32 are provided, and the multiple airbags 32 correspond to the multiple accommodation spaces one by one, and the airbags 32 are correspondingly installed in the multiple accommodation spaces, and the adjacent airbags 32 are connected through the air pipe. It should be noted that the thickness of the spacer 311 is less than the thickness of the airbag 32 after inflation. There are multiple airbags 32 installed. When a certain part of the door leaf body 1 is hit, the movable plate 2 moves toward the door leaf body 1 as a whole, but the airbag 32 at the impacted position will be compressed first. The gas in the airbag 32 here can be squeezed into the remaining airbags 32 while being compressed, which can avoid the airbag 32 at a certain place from being damaged by a large impact force to a certain extent. The setting of multiple airbags 32 makes it easy to replace the damaged airbags 32 in a targeted manner when some of the airbags 32 are damaged and aged, without replacing the entire airbag 32, thereby reducing costs.
[0029] Reference Figure 1 and Figure 2The energy absorbing member includes a sleeve rod 34, a piston rod 35 and an energy absorbing material plate 36. The sleeve rod 34 is a hollow cylindrical rod body provided at one end. A plurality of sleeve rods 34 are provided on the bottom wall of the mounting groove 11, and the open ends of the plurality of sleeve rods 34 all extend toward the buffer plate 31. A plurality of piston rods 35 extending toward the door leaf body 1 are provided on the buffer plate 31. The plurality of piston rods 35 correspond to the plurality of sleeve rods 34 one by one, and the piston rods 35 are slidably inserted in the sleeve rods 34. The energy absorbing material plate 36 is filled and provided between the buffer plate 31 and the door leaf body 1. The energy absorbing material plate 36 is made of common vibration-damping energy absorbing materials 36 on the market, such as EVA, PE, CR, PU foam, ACF, etc. When the buffer plate 31 is subjected to the impact force and moves toward the door leaf body 1, the energy absorbing material plate 36 can absorb the impact energy. During this process, the piston rod 35 is slidably inserted into the sleeve rod 34 , and the cooperation between the piston rod 35 and the sleeve rod 34 plays a role in positioning and guiding the movement of the buffer plate 31 .
[0030] Reference Figure 1 and Figure 2 Furthermore, a return spring 37 is provided inside the sleeve rod 34. One end of the return spring 37 is connected to the sleeve rod 34 and the other end is connected to the piston rod 35. The return spring 37 makes the piston rod 35 always have a tendency to move away from the door leaf body 1. After the impact, the return spring 37 pushes the buffer plate 31 to move away from the door leaf body 1 until the moving plate 2 is pressed against the slide groove 12, thereby achieving the effect of automatically resetting the moving door and the buffer door after the impact.
[0031] The implementation principle of an impact-resistant civil air defense door leaf frame structure in an embodiment of the present application is as follows: by arranging a buffer component 3 and a movable plate 2 on the door leaf body 1, when the civil air defense door is hit or impacted, the movable plate 2 is first subjected to the impact force, and the impact force is then transmitted to the buffer component 3 and the door leaf body 1 in sequence. In this process, the impact force transmitted from the movable plate 2 to the door leaf body 1 is reduced by the buffer component 3, thereby reducing the impact received by the door leaf body 1, thereby improving the impact resistance of the civil air defense door, and improving the problem that the civil air defense door is easily deformed, bent, or even broken when impacted.
