[0030] The terms "including" and "having" and any variations thereof in the specification and claims of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products or apparatuses.

[0031] The prior art has the following defects:

[0032] (1) In the prior art, when using the temporary sealing cover plate of the air-facing wall, there will still be a certain gap between the temporary sealing cover plate and the door frame during the closing process, which will cause polluted air from the outside to enter the sealed space, causing harm to people in the protection room.

[0033] (2) In the prior art, when fixing the temporary blocking cover plate of the air-facing wall, the cover plate is fixed by means of a door lock and a door frame. However, in the actual protection process, the door lock may become loose, resulting in a gap between the lock of the blocking plate and the door frame, causing outside air to flow into the protection space.

[0034] As an improvement, Figures 1 to 6 As shown, a preferred embodiment of the present application is as follows: it includes a fixed plate 1, a fixed rod 13 is fixedly connected to one side of the fixed plate 1, a fixed column 11 is rotatably connected inside the fixed rod 13, connecting plates 12 are fixedly connected to both ends of the fixed column 11, the connecting plate 12 is fixedly connected to the wall, a sealing assembly is arranged inside the fixed plate 1, and the sealing assembly includes a first slot body 21 opened inside the fixed plate 1; a gear 25 is rotatably arranged inside the first slot body 21, a rotating shaft 24 is fixedly connected to the middle of the gear 25, a rotating handle 2 is fixedly connected to the end of the rotating shaft 24 away from the gear 25, a connecting tooth plate 22 is slidably connected inside the first slot body 21, a side of the connecting tooth plate 22 close to the gear 25 is fixedly connected to a plurality of teeth 23, the plurality of teeth 23 are meshed with the gear 25, and a sliding plate 26 is fixedly connected to the middle of the connecting tooth plate 22.

[0035] Specifically, when using the temporary blocking cover plate for the air-facing wall, there will still be a certain gap between the temporary blocking cover plate and the door frame during the closing process, which will cause polluted air from the outside to enter the sealed space, causing harm to the personnel in the protection room;

[0036] Therefore, the utility model increases the airtightness of the temporary blocking cover plate of the empty wall by setting a certain structure. First, when the temporary blocking cover plate of the empty wall needs to be closed urgently, the temporary blocking cover plate of the empty wall is pushed to rotate around the fixed column 11. Then, when the temporary blocking cover plate of the empty wall is closed, the two rotating handles 2 on the surface of the temporary blocking cover plate of the empty wall are rotated at the same time, so that the rotating handle 2 can drive the rotating shaft 24, and the rotating shaft 24 will drive the gear 25 to rotate. The rotation of the gear 25 can drive the connecting tooth plate 22 in the first groove body 21, and then the connecting gear Plate 22 can drive the sliding plate 26 to slide downward, and then the connecting tooth plate 22 can be stuck into the groove of the door frame. At this time, the sliding plate 26 can seal the gap at the contact between the air-facing wall temporary blocking cover plate and the door frame, thereby preventing the external polluted air from entering the sealed space and protecting the people in the protected space; it solves the problem that during the closing process of the air-facing wall temporary blocking cover plate, there will still be a certain gap at the contact between it and the door frame, which will cause the external polluted air to enter the sealed space and cause harm to the people in the protected room.

[0037] like Figures 2 to 6 As shown, in this embodiment, sliders 27 are fixed to both sides of the connecting tooth plate 22 , and a slide groove 211 is opened at the position of each slider 27 in the first slot body 21 , and the connecting tooth plate 22 can slide along the slide groove 211 through two sliders 27 .

[0038] Specifically, in the process of the connecting tooth plate 22 sliding downward, by fixing the sliders 27 on both sides of the connecting tooth plate 22, the sliders 27 on both sides can slide in the slide grooves 211 on both sides of the inner wall of the first groove body 21 under the drive of the connecting tooth plate 22, thereby limiting the connecting tooth plate 22 and enabling the connecting tooth plate 22 to slide downward stably.

[0039] like Figure 5 As shown, in this embodiment, a second slot 28 is formed on one side of the connecting tooth plate 22 , and a plurality of first compression springs 210 are fixedly connected to the inner wall of the second slot 28 , and one end of each first compression spring 210 is fixedly connected to the same protrusion 29 .

[0040] Specifically, by opening a second groove 28 on one side of the connecting tooth plate 22, when the connecting tooth plate 22 is inserted into the groove of the door frame, the protrusion 29 in the second groove 28 at the bottom of the connecting tooth plate 22 is no longer limited by the first groove 21, and the rebound force of the first compression spring 210 makes the protrusion 29 protrude from the second groove 28. Then, the connection between the door frame and the air-facing wall blocking cover plate can be secondary sealed, thereby achieving a better sealing effect.

[0041] like Figure 6As shown, in this embodiment, second slots 28 are provided on both sides of the connecting tooth plate 22 , and a protrusion 29 is elastically provided in each second slot 28 .

[0042] Specifically, by opening a second groove 28 on both sides of the connecting tooth plate 22, when the connecting tooth plate 22 is inserted into the groove of the door frame, the protrusions 29 on both sides will pop out at the same time, thereby more effectively sealing the entire air-facing wall blocking cover plate and the door frame, thereby protecting the personnel in the protective space.

[0043] like Figure 1 As shown, in this embodiment, a plurality of fixing holes 14 are formed on the upper surface of the fixing plate 1 , and the cross section of each fixing hole 14 is “L”-shaped.

[0044] Specifically, a plurality of fixing holes 14 are opened on the upper surface of the fixing plate 1, and then an air inlet at one end of each fixing hole 14 is connected to an exhaust duct, thereby maintaining ventilation and preventing possible oxygen deficiency that may affect the health and safety of the internal personnel.

[0045] like Figure 1 As shown, in this embodiment, the top end of the fixed plate 1 is fixedly connected to the limiting block 3, and the circumferential surface of the limiting block 3 is rotatably connected to the limiting rod 31. A cylindrical groove 34 is provided at the top end of the fixed plate 1, and a limiting groove 38 is provided on the side of the fixed plate 1 close to the cylindrical groove 34. A second compression spring 36 is fixedly connected to the bottom wall of the cylindrical groove 34, and a plug column 35 is fixedly connected to the top end of the second compression spring 36. A handle 37 is fixedly connected to the circumferential surface of the plug column 35. Both ends of the limiting rod 31 are fixedly connected to torsion springs 33, and the end of each torsion spring 33 away from the limiting rod 31 is fixedly connected to the positioning shaft 32.

[0046] Specifically, when the fixing plate 1 is rotated and sealed with the door frame, by rotating the limit rod 31, the second compression spring 36 can drive the plug column 35 to be inserted into the slot on the door frame under the release of its own elastic force, and then the limit rod 31 can automatically rebound under the drive of the torsion spring 33, thereby achieving the effect of secondary fixing of the air-facing wall temporary blocking cover plate.

[0047] The working principle of the present application is as follows: first, when the temporary blocking cover plate of the air-wall needs to be closed urgently, the temporary blocking cover plate of the air-wall is pushed to rotate around the fixed column 11, and then when the temporary blocking cover plate of the air-wall is closed, the two rotating handles 2 on the surface of the temporary blocking cover plate of the air-wall are rotated at the same time, so that the rotating handle 2 can drive the rotating shaft 24, and the rotating shaft 24 will drive the gear 25 to rotate, and the rotation of the gear 25 can drive the connecting tooth plate 22 in the first groove body 21, and then the connecting tooth plate 22 can drive the sliding plate 26 to slide downward, and then the connecting tooth plate 22 can be stuck in the groove of the door frame, and at this time the sliding plate 26 can seal the gap at the contact between the temporary blocking cover plate of the air-wall and the door frame, thereby preventing the polluted air from the outside from entering the sealed space, and protecting the people in the protective space;

[0048] At the same time, the limiting rod 31 is rotated, and then the second compression spring 36 can drive the plug post 35 to be inserted into the slot on the door frame under the release of its own elastic force, and then the limiting rod 31 can automatically rebound under the drive of the torsion spring 33, achieving the effect of secondary fixing of the air wall temporary blocking cover plate;

[0049] In addition, during the downward sliding process of the connecting tooth plate 22, the sliders 27 are fixedly connected to both sides of the connecting tooth plate 22. The sliders 27 on both sides can slide in the slide grooves 211 on both sides of the inner wall of the first groove body 21 under the drive of the connecting tooth plate 22, thereby limiting the connecting tooth plate 22 and enabling the connecting tooth plate 22 to slide downward stably. Moreover, a second groove body 28 is provided on one side of the connecting tooth plate 22, and then when the connecting tooth plate 22 is inserted into the groove body of the door frame, the protrusion 29 in the second groove body 28 at the bottom end of the connecting tooth plate 22 is no longer limited by the first groove body 21, and the rebound force of the first compression spring 210 causes the protrusion 29 to protrude from the second groove body 28, and then the connection between the door frame and the air wall blocking cover plate can be secondary sealed, thereby achieving a better sealing effect.
