Description

Technical Field

[0001] This utility model relates to the field of civil defense door technology, specifically a detachable civil defense door accessory. Background Technology

[0002] Civil defense doors are the entrances and exits of civil air defense projects. They serve to block explosives and can play a significant protective role in times of crisis.

[0003] The prior art discloses patent application number "CN202421190474.2", which discloses a new type of reinforcement accessory for air defense doors, including an air defense door body, a reinforcement frame and a support plate. The reinforcement frame is disposed on the side wall of the air defense door body. The top of the support plate is slidably disposed on the reinforcement frame. The bottom of the reinforcement frame is rotatably hinged to a support arm. The end of the support arm is rotatably connected to the support plate through a shaft. The top of the reinforcement frame and the support plate are provided with telescopic components.

[0004] This type of reinforcement accessory for air-raid shelter doors can only provide reinforcement and support. However, in actual use, since air-raid shelter doors are simple in structure, the reinforcement accessory is relatively simple and cannot effectively reinforce and protect the air-raid shelter door. This results in poor strength of the air-raid shelter door, making it susceptible to damage from impacts, thereby reducing its service life and making it inconvenient to use. Utility Model Content

[0005] The purpose of this utility model is to provide a detachable air defense door accessory to solve the problems mentioned in the background art.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1 to 4As shown, a detachable air defense door accessory includes a wall 1, a door frame 2 is fixedly connected to one side of the wall 1 by bolts, two symmetrically distributed fixing seats 3 are fixedly provided on one side of the door frame 2, a rotating shaft block 4 is rotatably connected inside the two fixing seats 3, an air defense door body 5 is fixedly connected to one side of the two rotating shaft blocks 4, a sealing plate 6 is fixedly installed on one side of the air defense door body 5, and sealing strips 8 are fixedly connected around the sealing plate 6.

[0026] A first reinforcing square plate 7 is fixedly connected to one side of the sealing plate 6. Two support plates 9 are fixedly connected inside the first reinforcing square plate 7. With the support plates 9, the two support plates 9 can be positioned inside the first reinforcing square plate 7, making the main body of the air defense door 5 more stable and reliable to use. A double-ended screw rod 10 is rotatably connected inside the first reinforcing square plate 7. Two symmetrically distributed connecting plates 11 are threaded on the outer surface of the double-ended screw rod 10. Two embedded posts 12 for fixing the main body of the air defense door 5 are fixedly provided on one side of each of the two connecting plates 11. Four L-shaped locking blocks 13 for fixing the main body of the air defense door 5 are slidably engaged inside the first reinforcing square plate 7.

[0027] One side of the embedded column 12 penetrates through the first reinforced square plate 7 and extends to one side of the first reinforced square plate 7. One side of the L-shaped block 13 penetrates through the first reinforced square plate 7 and extends to one end of the first reinforced square plate 7. Two parallel vertical rods 14 are fixedly connected inside the first reinforced square plate 7. The outer surfaces of the two vertical rods 14 are slidably connected to the inside of the connecting plate 11. The two vertical rods 14 can guide and limit the movement trajectory of the two connecting plates 11, so that the embedded column 12 can move back and forth smoothly to open or close the air-raid shelter door. An operating handwheel 15 is fixedly installed on the outer surface of the double-ended screw 10.

[0028] A groove 16 is provided on one side of the wall 1 for snapping on the sealing plate 6 and the sealing strip 8. A second reinforcing square plate 17 is fixedly installed on the other side of the main body 5 of the air defense door. A movable baffle 18 is slidably connected to one side of the second reinforcing square plate 17. A connecting spring 19 is arrayed and connected to one side of the movable baffle 18 and one side of the second reinforcing square plate 17.

[0029] An array of reinforcing blocks 20 is fixedly installed on the other side of the movable baffle 18. Steel rods 22 are connected in an array inside the movable baffle 18. Four dampers 21 for buffering and protecting the main body of the air defense door 5 are fixedly connected to the other side of the movable baffle 18 and one side of the movable baffle 18. The dampers 21 can absorb the impact force on the movable baffle 18, effectively reducing the impact force on the air defense door and protecting the air defense door.

[0030] Four mounting bases 23 are fixedly provided at both ends inside the wall 1. A slot 24 is provided on one side of the mounting base 23. The slot 24 is adapted to the L-shaped block 13. One side of the L-shaped block 13 is engaged with one side of the mounting base 23 through the slot 24.

[0031] The two sides inside the wall 1 are fixedly provided with mounting base 25. One side of the mounting base 25 is provided with an embedding groove 26. The embedding groove 26 is adapted to the embedding column 12. One side of the embedding column 12 is engaged with one side of the mounting base 25 through the embedding groove 26.

[0032] The working principle of the detachable air-raid shelter door accessory provided by this utility model is as follows:

[0033] By rotating the main body 5 of the air-raid shelter door to the door frame 2, the sealing strip 8 at the sealing plate 6 can be pressed into the groove 16 of the door frame 2. Combined with the air-raid shelter door and the door frame 2, the main body 5 of the air-raid shelter door can be further sealed to ensure the airtightness of the air-raid shelter door. Then, the operating handwheel 15 on the double-ended screw 10 is rotated so that the two connecting plates 11 on the operating handwheel 15 move relative to each other. In this way, the four embedded posts 12 at the two connecting plates 11 can be engaged into the embedded grooves 26 of the four mounting seats 25. Then, the four L-shaped locking blocks 13 are pushed so that the four L-shaped locking blocks 13 can be engaged into the locking grooves 24 of the four mounting seats 23. At this time, the sealing plate 6, the embedded posts 12 and the L-shaped locking blocks 13 can constitute the air-raid shelter door accessories so as to lock the four sides of the main body 5 of the air-raid shelter door simultaneously. These accessories can play a role in dispersing the force and enhancing the stability when the air-raid shelter door is impacted, thereby reinforcing and protecting the air-raid shelter door, ensuring the strength of the air-raid shelter door and improving its service life.

[0034] A buffer assembly can be constructed using a movable baffle 18 equipped with a connecting spring 19 and a damper 21. When the air-raid shelter door is subjected to an impact, it will first come into contact with the buffer assembly, which can weaken the impact force and reduce the impact force transmitted to the air-raid shelter door. This buffer protects the air-raid shelter door and improves its impact resistance. Subsequently, the movable baffle 18 can be supported and reinforced by the steel bars 22 inside the movable baffle 18 and the reinforcing blocks 20 at the movable baffle 18, making the air-raid shelter door more robust and durable. This can significantly improve the load-bearing capacity and impact resistance of the air-raid shelter door, thereby ensuring that it remains intact when facing external impacts.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
