Description

Technical Field

[0001] This utility model relates to the field of airtight door technology, specifically to an earthquake-resistant and protective airtight door. Background Technology

[0002] Airtight doors, also known as civil defense doors, are door panels used at the entrances and exits of civil defense projects. They are one of the main structures of civil defense projects. Airtight doors are generally installed in underground parking lots. When closed, they form a sealed space to protect people from harm.

[0003] Airtight doors have high requirements for their function, and they are mainly structures that protect against various shock waves. When they are subjected to impacts or disasters such as floods, they will be subjected to shocks, which will cause damage to the door panels. In severe cases, the door panels will be deformed, making them unable to be opened and exposing the air-raid shelter space. Therefore, an earthquake-resistant airtight door is proposed. Utility Model Content

[0004] The technical problem this utility model aims to solve is that when subjected to impacts or disasters such as floods, the door panel will be subjected to shocks, which will damage the door panel. In severe cases, the door panel will be deformed and unable to be opened, and the airtight space will be exposed. This utility model provides an earthquake-resistant and protective airtight door that can mitigate the vibrations. The support components can reduce the degree of door panel deformation and prevent severe twisting that would prevent the door panel from opening.

[0005] The technical solution adopted by this utility model to solve the technical problem is: an earthquake-resistant and protective airtight door, including a door frame, a door panel rotatably connected to one side edge of the door frame, an inner groove opened in the door panel, a vertically upright plate fixedly connected to the middle side wall of the inner groove, and buffer top plates evenly fixedly connected to the two side walls of the vertical plates that are far apart from each other, the buffer top plates having an interlaced structure, and the gaps in the inner groove and located between the buffer top plates are filled with buffer sponge.

[0006] As a preferred technical solution of this utility model, the buffer top plate is a semi-circular elastic steel plate structure. The top of the buffer top plate is attached to the inner wall of the inner groove. A fixed horizontal column is provided inside the buffer top plate, and one end of the fixed horizontal column is fixedly connected to the side wall of the vertical plate.

[0007] As a preferred technical solution of this utility model, the two side walls of the fixed horizontal column away from the vertical plate are fixedly connected to the bifurcated support plate. The bifurcated support plate and the fixed horizontal column form a Y-shaped structure. The end of the bifurcated support plate away from the fixed horizontal column is attached to the inner wall of the buffer top plate. The bifurcated support plate is a hollow structure. The four side walls of the bifurcated support plate are all corrugated structures.

[0008] As a preferred technical solution of this utility model, the two side walls of the door frame that are far apart from each other are connected to embedded plates by screws. The embedded plates have a hollow structure and are movably connected to telescopic plates. One end edge of the telescopic plates is rotatably connected to a ground plate.

[0009] As a preferred technical solution of this utility model, a slot is uniformly and continuously opened on one side wall of the embedded plate, and a positioning groove is opened on the side wall of the embedded plate opposite to the slot, and an insert plate is inserted into the slot.

[0010] This utility model has the following advantages: because an inner groove is opened in the door panel, and two rows of buffer top plates are connected in the inner groove by vertical plates, when the door panel vibrates, the impact of the vibration can be reduced by the buffer top plates and buffer sponge. In addition, because the inner groove is opened, the weight of the embedded plate itself is reduced, thereby reducing the damage to the door panel caused by vibration. Similarly, the support of the buffer top plates can provide auxiliary support for the door panel, reduce the deformation of the door panel caused by vibration, ensure that the door panel maintains its original shape to the greatest extent, and avoid the door panel being unable to open or exposing the air-raid shelter space due to deformation.

[0011] The fixed crossbars and forked support plates installed inside the buffer top plate can provide auxiliary support for the buffer top plate, ensuring that the buffer top plate can provide additional support for the door panel itself. When the buffer top plate is deformed by force, the fixed crossbars and forked support plates can maintain its original shape to the greatest extent, thereby improving the maintenance of the door panel itself.

[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] Please refer to the following: Figure 1-3This utility model discloses an earthquake-resistant and protective airtight door, including a door frame 1. A door panel 2 is rotatably connected to one side edge of the door frame 1. An inner groove 6 is opened in the door panel 2. A vertically upright plate 7 is fixedly connected to the middle side wall of the inner groove 6. Buffer top plates 8 are evenly fixedly connected to the two side walls of the vertical plates 7 that are far apart from each other. The buffer top plates 8 have an interlaced structure. The gaps in the inner groove 6 and between the buffer top plates 8 are filled with buffer sponge 11.

[0018] The buffer top plate 8 is a semi-circular elastic steel plate structure. The top of the buffer top plate 8 is attached to the inner wall of the inner groove 6. A fixed horizontal column 9 is set inside the buffer top plate 8. One end of the fixed horizontal column 9 is fixedly connected to the side wall of the vertical plate 7. The two side walls of the fixed horizontal column 9 away from the vertical plate 7 are fixedly connected to the bifurcated support plate 10. The bifurcated support plate 10 and the fixed horizontal column 9 form a Y-shaped structure. The end of the bifurcated support plate 10 away from the fixed horizontal column 9 is attached to the inner wall of the buffer top plate 8. The bifurcated support plate 10 is a hollow structure. The four side walls of the bifurcated support plate 10 are all corrugated structures.

[0019] The technical effects of this solution are as follows: the buffer top plate 8 can support the door panel 2. When vibration occurs, the buffer top plate 8 can ensure that the appearance of the door panel 2 does not change significantly, avoiding the inability to open and close normally due to large deformation of the door panel 2, or even exposing the air-raid shelter space. Because the buffer top plate 8 is attached to the inner wall of the inner groove 6 rather than fixed, when deformation occurs, the side wall of the door panel 2 moves to relieve pressure, while the buffer top plate 8 can limit the deformation. Similarly, the fixed cross column 9 and the forked support plate 10 can ensure the stability of the buffer top plate 8 while allowing the buffer top plate 8 to move to a certain extent to relieve pressure, and the buffer sponge 11 can relieve the force.

[0020] Both sides of the door frame 1, which are far apart from each other, are connected to embedded plates 3 by screws. The embedded plates 3 have a hollow structure and are movably connected to telescopic plates 4. One end of the telescopic plates 4 is rotatably connected to a ground plate 5. A slot 12 is evenly opened through one side wall of the embedded plates 3. A positioning groove 13 is opened in the side wall of the embedded plates 3 that is opposite to the slot 12. An insert plate 14 is inserted into the slot 12.

[0021] The technical effect of this solution is as follows: embedded plates 3 are connected to both sides of the door frame 1, and a telescopic plate 4 is movably inserted into the embedded plate 3. The telescopic plate 4 can be pulled out and unfolded as needed, and then the ground plate 5 is placed on the ground. This can provide auxiliary support for the door frame 1. When pouring cement, the embedded plate 3 can be embedded in it, so that it is integrated with the wall, which improves the stability of the door frame 1 and also makes the door frame 1 maintain maximum stability under vibration.

[0022] Specifically, when using this utility model, the door frame 1 is placed in the designated position, and then the embedded plate 3 is connected to the door frame 1. Before connection, the telescopic plate 4 is pulled to a suitable length as needed, and the grounding plate 5 is placed on the ground. Holes can be drilled in the grounding plate 5 as needed, and screws are used to fix it to the ground. This completes the pre-setting of the embedded plate 3, providing stability for the door frame 1. After the telescopic plate 4 is pulled out, the insert plate 14 is inserted through the slot 12 into the corresponding positioning slot 13 to limit the telescopic plate 4. Then, cement is poured, so that the telescopic plate 4, the embedded plate 3 and the grounding plate 5 can be integrated into the wall, but still maintain a certain degree of independence. The cement will enter the embedded plate 3 along the other slots 12. After solidification, the strength of the embedded plate 3 can be improved. When the wall is damaged by vibration, the stability of the door frame 1 can still be guaranteed by the embedded plate 3 and other components.

[0023] When the door panel 2 vibrates due to an impact, the force is transmitted into the inner groove 6. The buffer sponge 11 can reduce the force. When the door panel 2 is subjected to deformation force, it will act on the buffer top plate 8. The support of the buffer top plate 8 can ensure the stability of the door panel 2 to the greatest extent. When the force is too great and the support is insufficient, the outer wall of the door panel 2 will move against the outer wall of the buffer top plate 8. In this way, the door panel 2 can undergo slight deformation under the constraint of the buffer top plate 8, thereby relieving the received force. Similarly, the buffer top plate 8 slides along one end of the buffer sponge 11 when subjected to force. At the same time, the bifurcated support plate 10 has a hollow structure and a wavy side wall, which can contract and deform under force, thereby relieving the force on the buffer top plate 8, and thus relieving the force on the door panel 2, ensuring the maximum stability of the door panel 2.

It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.

[0025] All other parts of this utility model that are not described in detail belong to the prior art, and therefore will not be described in detail here.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
