[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Reference Figure 1 - Figure 3 The utility model provides an embodiment: an anti-collision civil defense door, comprising a frame 1, a door panel 2 is arranged inside the frame 1, a slide groove 1 4 is opened inside the frame 1, a slide groove 2 5 is opened inside the door panel 2, the door panel 2 is slidably connected inside the slide groove 1 4, the frame 1 is slidably connected inside the slide groove 2 5, a rectangular array of buffer components are arranged inside the door panel 2, and the buffer components include a spring damper 6, one end of the spring damper 6 is fixedly connected to the inner wall of the slide groove 2 5, and the output end of the spring damper 6 is fixedly connected to the inner wall of the slide groove 1 4;

[0024] Specifically, a slide groove 4 is provided inside the frame 1, and a slide groove 2 5 is also designed inside the door panel 2. The two slide inside each other to facilitate the sliding of the door panel 2 inside the frame 1, so that the door panel 2 has movable control inside the frame 1, and the door panel 2 can produce movement changes when it is impacted. Spring dampers 6 are provided at the four corners inside the slide groove 2 5 to facilitate the door panel 2 to remain suspended inside the frame 1, ensuring that the door panel 2 can move when it is impacted. At the same time, the spring damper 6 can buffer the impact force on the door panel 2.

[0025] Reference Figure 2 and Figure 3 The inner wall of the frame 1 is rotatably connected to a transmission rod 2 11 that is symmetrical on both sides. One end of the transmission rod 2 11 is rotatably connected to a transmission rod 10. One end of the transmission rod 10 is rotatably connected to a movable block 8. The movable block 8 is slidably connected to a slide rod 7. Both ends of the slide rod 7 are fixedly connected to the inside of the slide groove 2 5. The outer wall of the slide rod 7 is sleeved with a spring 9.

[0026] Specifically, a slide rod 7 is provided inside the slide groove 2 5, and movable blocks 8 are provided on both sides of the slide rod 7. The spring 9 is provided between the movable blocks 8, so as to buffer the movable blocks 8 on both sides when they slide toward the center, and to ensure stability when the forces are offset. The inner wall of the slide groove 1 4 is connected to the movable blocks 8 through the transmission rod 2 11 and the transmission rod 1 10, so that the impact force is transferred to the movable blocks 8 and converted into a horizontal reverse force under the action of the transmission rod 10 and the transmission rod 2 11, thereby buffering the impact force received by the door panel 2.

[0027] Reference Figure 1 and Figure 4 The outer wall of the frame 1 is slidably connected to the door frame 3, the top of the frame 1 is rotatably connected to a rotating rod 14, one end of the rotating rod 14 is rotatably connected to the inner wall of the door frame 3, the top of the frame 1 is rotatably connected to a curved rod 13, one end of the curved rod 13 is rotatably connected to the inner wall of the door frame 3, one end of the curved rod 13 is fixedly connected to a connecting shaft 16, the connecting shaft 16 is rotatably connected to the inside of the door frame 3, the top of the outer wall of the connecting shaft 16 is fixedly connected to a gear 15, the top of the door frame 3 is fixedly connected to a hydraulic push rod 12, the output end of the hydraulic push rod 12 is fixedly connected to a slider 18, one side of the outer wall of the slider 18 is fixedly connected to a rack 19, the gear 15 is meshed with the rack 19, a slide groove 3 17 is provided at the top of the door frame 3, and the bottom of the slider 18 is slidably connected inside the slide groove 3 17;

[0028] Specifically, the hydraulic push rod 12 is arranged at the top of the door frame 3, and can control the movement of the slider 18, and the slider 18 slides in the slide groove 17 to ensure the smooth movement of the slider 18, and a rack 19 is arranged on one side of the slider 18, so that under the action of the rack 19, the movement of the slider 18 can drive the rotation of the gear 15, and the gear 15 is connected to the curved rod 13 through the connecting shaft 16, and the rotation of the gear 15 can make the curved rod 13 rotate, so that under the special shape of the curved rod 13, the frame 1 can be opened to the outside of the door frame 3, and the frame 1 is connected to the door frame 3 through the rotating rod 14, so that The auxiliary frame 1 opens smoothly. Since the distance between the two ends of the curved rod 13 is the same as the length of the rotating rod 14, the movement trajectories of the curved rod 13 and the rotating rod 14 are generally in a parallelogram shape. Therefore, when the frame 1 is retracted inside the door frame 3, the curved rod 13 and the rotating rod 14 are in a horizontal placement state. When the curved rod 13 and the rotating rod 14 push the frame 1 out, the initial movement amplitude of the rotating rod 14 and the curved rod 13 is small, and then gradually increases. Therefore, only a small gap needs to be reserved for the process of the frame 1 sliding out of the door frame 3. At the same time, the door does not need to be sealed, so the movement process of the frame 1 sliding out of the door frame 3 can be realized.

[0029] Working principle: when the door panel 2 is impacted, the door panel 2 can slide through the slide groove 1 4 and the slide groove 2 5, so that the door panel 2 can move. At the same time, the force will be converted into a horizontal direction through the transmission rod 2 11 and the transmission rod 1 10, so that the force is converted into a horizontal direction, thereby acting on the movable block 8 to make the movable blocks 8 on both sides slide toward the center on the slide rod 7, so that the opposite forces are offset under the buffering of the spring 9. When the frame 1 is switched, the hydraulic push rod 12 drives the slider 18 to slide in the slide groove 3 17, so that the rack 19 on the outer wall of the slider 18 drives the gear 15 to rotate, and the gear 15 will rotate the curved rod 13 through the connection of the connecting shaft 16, so that the frame 1 is opened to the outside with the assistance of the rotating rod 14.

[0030] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
