Description

Technical Field

[0001] This utility model relates to the field of civil defense doors, specifically to a fire-resistant, highly sealed civil defense door. Background Technology

[0002] Civil defense doors are doors specifically designed for fire prevention, smoke isolation, and prevention of the spread of harmful gases. They are typically installed in underground civil defense projects, public buildings, and other places requiring high levels of security protection. These doors not only effectively address the threats posed by fire but also help protect the safety of people and property.

[0003] While current air-raid shelter doors can effectively achieve fire-resistant high-sealing gasket functions, they are often opened and closed by turning a handwheel, which requires turning it multiple times in both directions, making it time-consuming. Moreover, the fire-resistant function is often achieved through the material itself, so the fire-resistant performance still needs further improvement.

[0004] Therefore, it is necessary to invent a fire-resistant, highly airtight civil defense door. Utility Model Content

[0007] The double-layer sealing assembly includes a groove, which is formed at one end of the door frame near the door leaf. The end of the door leaf near the door frame is fixed with an integral protrusion. Sealing gaskets are fixed on the inner surface of the groove and the edge of the protrusion.

[0008] Preferably, the switch assembly includes two limiting seats, which are symmetrically fixed at the end of the door leaf away from the door frame, and two limiting grooves are formed on the side of the limiting seats from top to bottom.

[0009] Preferably, the switch assembly further includes two vertically arranged insert rods, the opposite ends of the two insert rods are respectively inserted into two limiting seats, and each insert rod end is fixed with a lever, the lever being rotatable and inserted into the limiting groove.

[0010] Preferably, limit rings are symmetrically fixed on the upper and lower surfaces of the door leaf, and the two insertion rods pass vertically through the two limit rings respectively.

[0011] Preferably, the upper and lower ends of the door frame are symmetrically fixed with fixing plates, and each fixing plate is provided with a socket hole, and the two plug rods can be inserted into the two socket holes respectively.

[0012] Preferably, the fire protection component includes a water supply bend, which is fixed in the wall. The top of the water supply bend passes through the door frame, and the bottom of the water supply bend is fixedly connected to a drain pipe. The bottom of the drain pipe is fixedly connected to a plurality of water spray nozzles, all of which are inclined toward the door leaf. The top of the water supply bend is fixedly connected to a water supply hose.

[0013] Preferably, the fire protection component further includes a water storage tank, with a water pump connected to the bottom pipe of the water storage tank, and the top end of the water delivery hose is fixedly connected to the output end of the water pump.

[0014] Preferably, the sealing gasket has a stepped cross-section, and the two sealing gaskets abut against each other when the door leaf and the door frame are closed.

[0015] The beneficial effects of this utility model are: by using the wall, door frame, door leaf, fireproof components, double-layer sealing components and switch components in combination, the door frame and door leaf can achieve a double high sealing function, effectively blocking smoke and preventing the spread of harmful gases, and it is convenient to open and close, saving time and effort.

[0021] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0022] Please refer to the appendix. Figures 1-4 This utility model provides a fireproof, high-sealing civil defense door, which is fixedly installed on the wall 1. It includes a door frame 2, and a door leaf 3 is hinged on the door frame 2. It should be noted that both the door frame 2 and the door frame 3 are made of steel, which has fireproof function and good strength. It also includes fireproof components, which are set on the wall 1 and the door frame 2. A double-layer sealing component is set between the door frame 2 and the door leaf 3, and a switch component is set between the door frame 2 and the door leaf 3.

[0023] The double-layer sealing assembly includes a groove 4, which is located at one end of the door frame 2 near the door leaf 3. A protrusion 5 with an integral structure is fixed at one end of the door leaf 3 near the door frame 2. Sealing gaskets 6 are fixed on the inner surface of the groove 4 and the edge of the protrusion 5. The cross-section of the sealing gasket 6 is stepped. When the door leaf 3 and the door frame 2 are closed, the two sealing gaskets 6 abut against each other. Specifically, under the sealing effect of the double-layer sealing gaskets 6, the door frame 2 and the door leaf 3 can achieve a double high-sealing function, effectively blocking smoke and preventing the diffusion of harmful gases.

[0024] The switch assembly includes two limit seats 7, which are symmetrically fixed to the end of the door leaf 3 away from the door frame 2. Two limit grooves 8 are formed on the side of each limit seat 7 from top to bottom. Figure 3 As shown), the switch assembly also includes two vertically arranged plug rods 9. The opposite ends of the two plug rods 9 are respectively inserted into two limit seats 7. Each plug rod 9 has a lever 10 fixed at its end. The lever 10 can be rotatably inserted into the limit groove 8. Specifically, the user can rotate the plug rod 9 by moving it forward and backward with the lever 10, and then move the plug rod 9 up and down to control the lifting and lowering of the plug rod 9. The plug rod 9 can also be moved up or down by rotating the lever 10 into different limit grooves 8.

[0025] Limiting rings 11 are symmetrically fixed on the upper and lower surfaces of the door leaf 3. Two insert rods 9 pass vertically through the two limiting rings 11 respectively. Under the limiting action of the limiting rings 11, the insert rods 9 can move stably up and down. Fixing plates 12 are symmetrically fixed at the upper and lower ends of the door frame 2. Each fixing plate 12 has a hole 13. The two insert rods 9 can be inserted into the two holes 13 respectively. Specifically, when the insert rod 9 moves and is inserted into the hole 13, the door frame 2 and the door leaf 3 can be closed and fixed. When the insert rod 9 moves out of the hole 13, the door leaf 3 can be opened. That is, the door frame 2 and the door leaf 3 can be opened and closed conveniently, saving time and effort.

[0026] The fire protection component includes a water supply bend 14, which is fixed inside the wall 1. The top of the water supply bend 14 passes through the door frame 2, and the bottom of the water supply bend 14 is fixedly connected to a drain pipe 15. The bottom of the drain pipe 15 is fixedly connected to several water nozzles 16, all of which are inclined towards the door leaf 3. The top of the water supply bend 14 is fixedly connected to a water supply hose 17. The fire protection component also includes a water storage tank 18, with a water pump 19 connected to the bottom of the water storage tank 18. The top of the water supply hose 17 is fixedly connected to the output end of the water pump 19. Specifically, when the water pump 19 is running, it can draw water out of the water storage tank 18, and then pump it into the drain pipe 15 through the water supply hose 17 and the water supply bend 14. Finally, the water is sprayed out through the several water nozzles 16, which can not only form a water curtain to improve fire protection performance, but also spray water to cool the surface of the door leaf 3.

[0027] It should be noted that in this utility model, the water supply hose 17 can also be flanged to the fire water pipe of the building, and the fire prevention function can be achieved through the fire water in the fire water pipe.
