An oxygen cylinder 19 is provided in the inner sealing sleeve 13.

This embodiment has the following advantages:

In the event of a fire, the inflator is used to inflate the gap between the outer sealing sleeve 14 and the inner sealing sleeve 13, so that the outer sealing sleeve 14 and the heat insulating sleeve 11 are expanded outward, and the outer sealing sleeve 14 is pulled through the heat insulation during the expansion process. The rope 16 drives the inner sealing sleeve 13 to expand, so that a space capable of accommodating people is formed inside the inner sealing sleeve 13. People enter the inner sealing sleeve 13 from the outside of the heat insulation sleeve 11 through the through sleeve 12, and then use the closing component to close the opening of the through sleeve 12, thereby preventing external air from entering the inner sealing sleeve 13, thereby preventing the outside of the heat insulation sleeve 11. Hot air and smoke enter the inner sealing sleeve 13, so that people can avoid the hot air and dense smoke of the fire, and achieve a better effect of blocking heat and blocking the dense smoke.

The heat-insulating sleeve 11 blocks the heat-insulating air, which improves the heat-insulating effect and also protects the outer sealing sleeve 14. The outer sealing sleeve 14 and the inner sealing sleeve 13 are only connected by the heat-insulating drawstring 16 and the heat-insulating support 15, and most of the gap between the outer sealing sleeve 14 and the inner sealing sleeve 13 is filled by the gas filled by the inflator , So as to further improve the heat insulation effect through the gas barrier heat insulation capacity. The heat insulation drawstring 16 and the heat insulation support 15 are made of heat insulation material, which can directly reduce the heat transferred from the outer sealing sleeve 14 to the inner sealing sleeve 13, thereby further improving the heat insulation effect.

When there is no fire, the inflator does not inflate gas into the outer sealing sleeve 14 to discharge the gas in the inner insulating sleeve 11, so that the inner sealing sleeve 13, the outer sealing sleeve 14, the heat insulating sleeve 11 and the communication can be wound. The sleeve 12 can roll the inner sealing sleeve 13, the outer sealing sleeve 14, the heat insulation sleeve 11, and the through sleeve 12 into a small cylindrical or cuboid, which can effectively reduce the volume when not in use, thereby providing convenience Placement and convenient handling. The rescue cabin is especially suitable for presets in corridors, refuges and fire trucks. When people are trapped in forest fires, house fires and other disasters and cannot escape temporarily, the rescue cabin can provide people with good protection effects. It can very effectively increase the chance of people surviving in a disaster.

When it is necessary to close the opening of the through sleeve 12, pull the outer insulation cable 23 to reduce the length of the part of the outer insulation cable 23 located inside the outer connecting sleeve 21, and drive the outer connecting sleeve 21 to shrink, so that the outer connecting sleeve 21 drives the heat insulation sleeve 11 to shrink to the inside of the opening of the through sleeve 12 until the opening of the through sleeve 12 is closed, thereby achieving the effect of closing the opening of the through sleeve 12, thereby effectively blocking air and dense smoke. In addition, the opening of the through sleeve 12 is closed by driving the heat insulation sleeve 11, so that the heat insulation effect at the opening of the through sleeve 12 is taken into account, and the rescue cabin as a whole has a better heat insulation effect. When the tensioned outer heat insulation cable 23 is tightened, the outer heat insulation cable 23 is locked by the outer locking mechanism, so that the opening of the through sleeve 12 is kept in a closed state.

The outer wedge-shaped pin 26 is inserted into the outer connecting ring 24 and squeezed through the outer insulating cable 23 of the outer connecting ring 24, thereby preventing the outer insulating cable 23 from moving in the outer connecting ring 24 through friction, thereby achieving locking The effect of thermal insulation cable 23. The outer elastic member 25 exerts an elastic force on the outer wedge-shaped pin 26 so that the outer wedge-shaped pin 26 has a tendency to keep the outer insulating cable 23 locked.

Pull the inner heat insulation cable 33 to reduce the length of the part of the inner heat insulation cable 33 located inside the inner connecting sleeve 31, and drive the inner connecting sleeve 31 to shrink, so that the inner connecting sleeve 31 drives the heat insulation sleeve 11 to the through sleeve 12 The inner side of the opening is contracted until the opening of the through sleeve 12 is closed, thereby achieving the effect of closing the opening of the through sleeve 12, which can effectively block the air and dense smoke. In addition, the opening of the through sleeve 12 is closed by driving the heat insulation sleeve 11, so that the heat insulation effect at the opening of the through sleeve 12 is taken into account, and the rescue cabin as a whole has a better heat insulation effect. When the tensioned inner thermal insulation cable 33 is tightened, the internal thermal insulation cable 33 is locked by the internal locking mechanism, so that the opening of the through sleeve 12 is kept in a closed state.

The inner connecting sleeve 31 and the outer connecting sleeve 21 are respectively located at the two ends of the through sleeve 12, so that by closing the openings at both ends of the through sleeve 12, the blocking effect of hot air and dense smoke can be further improved.

The inner wedge-shaped pin 36 is inserted into the inner connecting ring 34 and squeezed through the inner insulating cable 33 of the inner connecting ring 34, thereby preventing the inner insulating cable 33 from moving in the inner connecting ring 34 through friction, thereby achieving locking The effect of the inner insulation cable 33. The inner elastic member 35 exerts elastic force on the inner wedge pin 36 so that the inner wedge pin 36 has a tendency to keep the inner heat insulation cable 33 locked.

The gas generating agent 43 is heated by the activation assembly 44 to chemically decompose the gas generating agent 43 and generate gas. The gas enters the outer sealing sleeve 14 through the conduit 42 from the reaction tank 41, thereby realizing the function of inflating the inside of the outer sealing sleeve 14 . After the outer sealing sleeve 14 is inflated, the reaction tank 41 is removed from the pipe 42 so that the positions of the heat insulating sleeve 11 and the inner connecting sleeve 31 can be conveniently adjusted. At the same time, the one-way valve 47 prevents the gas inside the outer sealing sleeve 14 The outside of the outer sealing sleeve 14 is discharged from the duct 42.

The arrangement of the heat-resistant connecting rope 17 can effectively improve the structural strength of the thermal insulation sleeve 11 and prevent the thermal insulation sleeve 11 from being broken by objects in the fire field. The heat-insulating pull cord 16 and the heat-resistant connecting cord 17 are fixedly connected, which can improve the structural stability between the heat-insulating pull cord 16 and the heat-insulating sleeve 11.

By blocking the amount of heat insulation by the heat insulation board 18, the heat insulation effect can be further improved. The heat insulation board 18 can block objects splashing to the heat insulation sleeve 11, prevent the objects from directly hitting the heat insulation sleeve 11, and play the effect of protecting the heat insulation sleeve 11. At the same time, the objects can roll quickly from the heat insulation board 18 through the action of gravity. It can prevent the object from continuously transferring heat to the thermal insulation sleeve 11 on the thermal insulation board 18.

The oxygen cylinder 19 is used to provide oxygen to the person in the inner sealing sleeve 13 to increase the time that the person can avoid danger in the rescue cabin.
