Description

Technical Field

[0001] The utility model relates to the field of civil air defense doors, in particular to an anti-impact structure of a civil air defense door. Background Art

[0002] Civil defense doors are the doors at the entrances and exits of people's defense projects. The classification of civil defense doors is relatively clear, including ordinary single-leaf and double-leaf protective closed doors and closed doors, movable threshold single-leaf and double-leaf protective closed doors and closed doors and other civil defense equipment.

[0003] The published patent with authorization announcement number CN211874304U discloses a modular civil air defense door, including a wall fixing system and a civil air defense door structural system, wherein the wall fixing system includes an electromagnetic switch and a wall, wherein the electromagnetic switch is mounted on the wall; the civil air defense door structural system includes a rotating fixing structure, a rotating head, and a civil air defense door main structure, wherein the rotating fixing structure is fixed to the wall, the civil air defense door main structure is connected to the rotating fixing structure via the rotating head and rotates around the rotating fixing structure via the rotating head, and a filler is provided inside the civil air defense door main structure. By designing the filler of the civil air defense door and assembling it, the present utility model can improve the convenience of installation and maintenance of the civil air defense door, speed up the transition from peacetime to wartime of the civil air defense project, and enhance the reliability of the protective equipment of the civil air defense project. This modular structural design can also be applied to wartime command posts, external armor, hangar doors and other fields.

[0004] Existing civil defense doors have flame-retardant and high-rigidity structural characteristics, but when an impact is applied to a certain part of the civil defense door body, the civil defense door is still unstable. Existing impact-resistant structures generally use materials or components such as springs or shock-absorbing cotton to achieve shock-absorbing effects. However, the springs installed inside the civil defense door will lose their elasticity over time, thereby reducing the buffering effect and being inconvenient to replace and repair. Utility Model Content

[0005] The utility model provides an anti-impact structure for a civil defense door to solve the problems raised in the above background technology.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] An impact-resistant structure for a civil air defense door, comprising a frame body, two sets of limit frames welded to the frame body, a hinge structure mounted on one side of the limit frames, and further comprising:

[0008] The civil air defense door body is flip-mounted with the frame body through the hinge structure and is used to open and close the passage of the frame body;

[0009] A connecting portion is mounted on the civil air defense door body, and one side of the connecting portion is connected to the hinge structure;

[0010] The civil defense door docking part is installed on the connecting part, including an internal installation groove and an X-shaped steel frame welded and installed inside the installation groove, which is used to assist the connecting part in ensuring the impact resistance of the civil defense door.

[0011] Furthermore, two groups of top auxiliary blocks and bottom auxiliary blocks are welded and installed inside the connecting part, an extrusion block is installed inside the connecting part to cooperate with the top auxiliary blocks and the bottom auxiliary blocks, and two groups of clamping welding grooves are opened on the connecting part.

[0012] The top auxiliary block, the bottom auxiliary block and the extrusion block cooperate with each other to increase the overall protection effect of the civil air defense door.

[0013] Furthermore, tensioning blocks are welded and installed on both sides of the extrusion block, and two sets of extrusion surfaces are provided on the extrusion block. The tensioning block is provided with an upper end force-bearing surface, a fitting surface, a lower end force-bearing surface and a bearing plate.

[0014] By contacting the extrusion surface with the inner wall of the connection part, the joint part of the civil defense door is supported, thereby improving the impact resistance of the joint part of the civil defense door.

[0015] Furthermore, the top auxiliary block is provided with a force conducting surface, and the bottom auxiliary block is provided with a clamping surface and a bearing surface.

[0016] The force is applied by the top auxiliary block from the force transmission surface downward to the upper force-bearing surface, thereby causing the upper force-bearing surface to generate pressure in the direction of the joint part of the civil defense door.

[0017] Furthermore, the force-conducting surface and the upper-end force-bearing surface cooperate and fit with each other, the snap-fit ​​surface and the bearing plate cooperate and fit with each other, and the bearing surface and the lower-end force-bearing surface cooperate and fit with each other.

[0018] The force is transmitted to the clamping surface through the bearing plate, and then to the bearing surface by the clamping surface. The bearing surface squeezes the force surface at the lower end to move it upward, and also generates a pressure in the direction of the civil defense door docking part, so that the front force on the civil defense door docking part is decomposed, thereby increasing the impact resistance of the civil defense door docking part.

[0019] Furthermore, a locking portion is installed on the front side of the civil air defense door docking portion.

[0020] The locking and closing of the civil air defense door is ensured by the locking portion.

[0021] Furthermore, a clamping welding plate that cooperates with the clamping welding groove is clamped and welded on the connecting portion.

[0022] The clamping welding plate and the clamping welding groove are clamped together for welding, thereby ensuring the stability of the clamping welding plate.

[0023] Furthermore, a high-density steel frame portion is welded and installed on the X-shaped steel frame, and a filling groove is opened on the X-shaped steel frame.

[0024] The X-shaped steel frame increases the rigidity and strength of the civil air defense door, while improving the impact resistance of the civil air defense door joint. At the same time, the filling slot can be filled with shock-absorbing cotton to increase its impact resistance.

[0025] Beneficial effects of the utility model:

[0026] The impact-resistant structure of the civil air defense door transmits the force from the bearing plate to the clamping surface, and from the clamping surface to the bearing surface, and the bearing surface squeezes the lower force surface to move it upward, and also generates a pressure in the direction of the civil air defense door joint part, so that the front force on the civil air defense door joint part is decomposed, thereby increasing the impact resistance of the civil air defense door joint part. At the same time, the X-shaped steel frame welded and installed inside the installation groove, and the high-density steel frame part welded and installed on the X-shaped steel frame increase the rigidity and strength of the civil air defense door. At the same time, the filling groove can be filled with shock-absorbing cotton, which also increases its impact resistance. When maintenance is needed, the clamping welding plate is removed to achieve the maintenance effect inside, and there are no mechanical components inside, reducing the probability of maintenance.
