Embodiment 1

[0028] refer to Figure 1-5 , a protective airtight door for shockproof, comprising a door frame assembly, the door frame assembly is located in the wall where the airtight door is located, and the door frame assembly is a fixed part of the airtight door; the door frame assembly includes a bottom beam 1, a side beam 4 and a top beam 14 , both ends of the side beam 4 are provided with mortise 41, both ends of the bottom beam 1 and the top beam 14 are provided with mortise holes 17, and the ends of the side beam 4 pass through the mortise between the tenon 41 and the bottom beam 1 and the top beam 14 The holes 17 are fixed with mortise and tenon tenon. One side of the inner wall of the mortise hole 17 is vertically inserted with a board 12, and the board 12 is a trapezoidal structure. The side of the board 12 is parallel to the outer wall of one side of the tenon 41. There is a gap between the outer wall and the outer wall of the tenon 41, and the inner wall of the gap is vertic...

Embodiment 2

[0034] refer to figure 1 , 2And 6, a protective airtight door for shockproof, the main difference between this embodiment and embodiment 1 is that in this embodiment, what is fixed in the integrated door frame 51 is not the reinforcement beam 52, but the mixed layer 53 instead, wherein The mixed layer 53 is formed by parallel lamination of at least five layers of woven fabrics mixed with metal wires. The fabrics are made of aramid fibers with a yarn count of 1500d-1600d. , to improve the puncture and impact resistance of the inner side, in which the metal wire of the cloth blend is Cr 18 Ni 14 Mo 3 Drawn metal for added strength and rigidity.

[0035] Used in airtight doors, the reinforcing beam 52 is welded and fixed inside the door frame by X-shaped steel bars to improve the support of the frame, and the mixed layer 53 can be clamped inside, and the cloth layer in the mixed layer 53 is distributed on the reinforcing beam 52 On the outer walls on both sides, the reinforc...

Abstract

The invention discloses a shockproof protective sealing door. The shockproof protective sealing door comprises a door frame assembly, wherein the door frame assembly is arranged in a wall where the sealing door is located, and the door frame assembly is a fixing part of the sealing door; and positioning insertion rods which are vertically connected and are distributed in parallel are arranged at the bottom end of the door frame assembly, and the bottom ends of the positioning insertion rods are fixedly connected to the bottom side of the wall where the sealing door is located. According to the shockproof protective sealing door, tenon-and-mortise structures are arranged at the joints of the four corners of a door frame and are combined with two elastic pieces by using the tenon-and-mortise principle of a galloping pin so as to form elastic supporting for transverse extrusion deviation, the longitudinal and transverse shockproof performance of the door frame body is improved, the door body is formed by three-layer combined extrusion, the outer layer is an energy absorption layer, the middle layer is a supporting layer, and the inner layer is an anti-explosion layer, so that when impact or explosion occurs, impact can be gradually reduced, a door body fixing lock structure on the inner anti-explosion layer cannot be influenced, a door body cannot fails when being opened and closed, and the in-out safety of the sealing door is improved.

Description

technical field [0001] The invention relates to the technical field of civil air defense engineering, in particular to an anti-shock protective airtight door. Background technique [0002] Civil air defense projects, also known as civil air defense fortifications, refer to underground protective buildings built separately to protect personnel and material shelter, civil air defense command, and medical rescue in wartime, as well as basements that can be used for air defense in wartime built in combination with ground buildings. [0003] The civil air defense project is an important facility to prevent sudden enemy attacks, effectively cover personnel and materials, and preserve war potential; it is an engineering guarantee to persist in urban combat and long-term support for anti-aggression wars until victory. [0004] After retrieval, the authorized publication number is CN209510085U patent, which discloses a civil air protection airtight door with a protective observation ...
