[0049] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0050] Reference Figure 1-Figure 7 The multi-layer sealed civil air defense door includes: a door frame 11, a door panel 12, a sealing plate 13, and a first sealing strip 16.

[0051] The door panel 12 and the door frame 11 are relatively rotated by hinges, and the door panel 12 and the door frame 11 are locked or opened by a door lock 15 and a door handle 14 .

[0052] The sealing plate 13 is fixedly connected to the door panel 12, and the first sealing strip 16 is fixedly connected to the sealing plate 13, and the first sealing strip 16 is distributed along the vertical frame of the door panel 12. Two symmetrical lifting grooves 17 are provided at the upper and lower ends of the door frame 11, and a sliding groove 21 is provided in the door panel 12 and the sliding groove 21 is respectively connected to the lifting grooves 17 on both sides.

[0053] There are two sets of sealing components, which are respectively arranged in two lifting grooves 17. The sealing components include: a mounting strip 18, a second sealing strip 19, a baffle 20, and a connecting plate 23. There are two mounting strips 18, which are respectively slidably connected to the groove wall of the lifting groove 17. The mounting strip 18 is provided with a slot 27, which runs through both ends of the mounting strip 18. The second sealing strip 19 is T-shaped and inserted into the slot 27. A plurality of convex strips are provided on the end of the second sealing strip 19 away from the mounting strip 18. A rotating shaft 29 is fixedly connected to one end of the mounting strip 18. The rotating shaft 29 is rotatably connected to the baffle 20. The rotating shaft 29 is made of high-temperature resistant rubber material and has rotational friction with the baffle 20. The connecting plate 23 is fixedly connected to the two mounting strips 18, and the two mounting strips 18 are fixedly connected to each other through the connecting plate 23.

[0054] The control member is arranged in the door panel 12, and is used to synchronously control the two sets of sealing components to seal. The control member includes: a control shaft 24, a rotating disk 26, a rack 22, and a gear 25. The control shaft 24 is rotatably connected to the door panel 12, and a part of the control shaft 24 extends into the sliding groove 21. A sealing ring 28 is sleeved on the part of the control shaft 24 inserted into the door panel 12. The inner ring of the sealing ring 28 is interference-fitted with the control shaft 24, and the outer ring of the sealing ring 28 is bonded and fixed to the inner wall of the door panel 12. Two rotating disks 26 are provided and are respectively fixedly connected to the two ends of the control shaft 24. The gear 25 is fixedly connected to a part of the control shaft 24 located in the sliding groove 21. Two racks 22 are provided and are respectively slidably connected to the side walls of the sliding groove 21. The two racks 22 are arranged staggered with each other. The gear 25 is located between the two racks 22 and meshes with the two racks 22. One end of the two racks 22 is respectively fixedly connected to the two connecting plates 23. The first sealing strip 16 , the second sealing strip 19 and the sealing ring 28 are made of high temperature resistant rubber.

[0055] Working or installation process:

[0056] Initial state: the plurality of mounting strips 18 are respectively located in the lifting slots 17 on both sides, and the second sealing strip 19 does not contact the inner frame top wall of the door frame 11 and the ground, the second sealing strip 19 is inserted into the slot 27 and the two ends of the second sealing strip 19 are flush with the two end notches of the slot 27, the baffle 20 blocks the side notches of the slot 27, and the second sealing strip 19 cannot slide in the slot 27 (such as Figure 5 shown);

[0057] When sealing is required, the door panel 12 is rotated and rotated into the door frame 11, and the door handle 14 is rotated and the lock tongue of the door lock 15 is inserted into the lock hole in the door frame 11, so as to achieve the fixation of the door frame 11 and the door panel 12; at this time, the sealing plate 13 follows the door panel 12 and rotates, the door panel 12 is completely located in the inner frame of the door frame 11, and the side wall of the sealing plate 13 contacts the outer frame side wall of the door frame 11. Since the sealing plate 13 is installed with a first sealing strip 16 distributed along the vertical frame of the door panel 12, at this time, the first sealing strip 16 is located between the side wall of the sealing plate 13 and the outer frame side wall of the door frame 11, and the first sealing strip 16 is squeezed by the side wall of the sealing plate 13 and the outer frame side wall of the door frame 11, so as to seal the vertical side edge of the door panel 12;

[0058] Then, the turntable 26 is rotated, and the turntable 26 drives the control shaft 24 to rotate, and the control shaft 24 drives the gear 25 to rotate, and the gear 25 meshes with the racks 22 on both sides, thereby driving one of the racks 22 to move downward and the other rack 22 to move upward; wherein, the lower end of the rack 22 moving downward is fixedly connected to the connecting plate 23 below, thereby driving the two mounting strips 18 below to move downward, and the two downward movements drive the two second sealing strips 19 to move downward, until the convex strips of the second sealing strips 19 are pressed against the ground, and at this time, the two second sealing strips 19 located above the door panel 12 are pressed against the top wall of the inner frame of the door frame 11;

[0059] The gap between the top wall of the door panel 12 and the top wall of the inner frame of the door frame 11 is sealed by the plurality of second sealing strips 19 located in the top wall and the bottom wall, and the gap between the bottom wall of the door panel 12 and the ground is sealed. The plurality of second sealing strips 19 and the first sealing strip 16 are provided to achieve a multi-layer sealing effect.

[0060] Since the inner ring of the sealing ring 28 has an interference fit with the control shaft 24, and the outer ring of the sealing ring 28 has an interference fit with the inner wall of the door panel 12, the control shaft 24 cannot rotate or slide when not subject to external human force, so that the second sealing strip 19 can press against the ground and the top wall of the inner frame of the door frame 11 for a long time without being affected by external human force.

[0061] After the second sealing strip 19 is pressed against the ground and the top wall of the inner frame of the door frame 11 for a long time, the second sealing strip 19 needs to be replaced, the door panel 12 is opened and the baffle 20 is rotated so that the side wall of the baffle 20 no longer blocks the side notch of the slot 27 (such as Figure 7As shown), the old second sealing strip 19 is pulled out from the side wall notch of the slot 27, and the new second sealing strip 19 is inserted into the slot 27, and then the baffle 20 is rotated again so that the baffle 20 rotates around the rotating shaft 29 and rotates to the side notch position of the slot 27, and the baffle 20 blocks the second sealing strip 19 again to prevent the second sealing strip 19 from sliding in the slot 27.

[0062] The above descriptions are only some preferred embodiments of the present disclosure and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the invention involved in the embodiments of the present disclosure is not limited to the technical solutions formed by a specific combination of the above-mentioned technical features, but should also cover other technical solutions formed by any combination of the above-mentioned technical features or their equivalent features without departing from the above-mentioned inventive concept.
