It has important practical significance for improving the disaster resistance of mines and reducing the major economic losses and casualties caused by fire in mines.

[0003] The existing airbag type quick sealing device adopts a foot-operated air pump to inflate the airbag during use. During this process, it takes six minutes of pedaling to fill the airbag, which results in low inflation efficiency, long time consumption and high physical exertion. The existing sealing curtain and the airbag arch frame are connected by hooks, which is very laborious and may cause unhooking. Utility Model Content

[0006] As a preferred technical solution of the utility model, the first fixing sticker and the second fixing sticker are made of Velcro, and the first fixing sticker and the second fixing sticker are respectively a fleece-surface Velcro and a thorn-surface Velcro.

[0007] As a preferred technical solution of the utility model, the first fixing sticker and the second fixing sticker are on the same surface of the sealing curtain, and the distance between the first fixing sticker and the second fixing sticker is longer than the circumference of the airbag arch.

[0008] As a preferred technical solution of the utility model, circular holes are provided at both ends of the outer edge of the sealing curtain, and the diameter of the circular holes is larger than the diameter of the inflation joint.

[0009] As a preferred technical solution of the utility model, the quick inflation component includes a plug, the inner wall of the plug is fixedly sleeved with a vent pipe, the outer wall of the vent pipe away from the plug is fixedly sleeved with a quick connector 1, and the inner wall of the quick connector 1 is clamped with a quick connector 2.

[0010] As a preferred technical solution of the utility model, the inner wall of the quick connector 2 is fixedly sleeved with a connecting pipe 1, the outer wall of the connecting pipe 1 is fixedly equipped with a valve, the inner wall of the valve is fixedly equipped with a connecting pipe 2, the end of the connecting pipe 2 away from the valve is fixedly sleeved with a pressure regulator, and the outer wall of the pressure regulator is fixedly sleeved with a gas cylinder.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. The mine airbag type rapid closed inflation device has high-pressure air in the gas cylinder. The high-pressure air is reduced through the pressure regulator to reduce the high-pressure air of 25MPa to low-pressure air of 0.8MPa. The low-pressure air of 0.8MPa enters the airbag arch through connecting pipe 2, connecting pipe 1 and the ventilation pipe. At this time, the airbag arch quickly inflates. This process only takes 20 seconds, thereby solving the problem that the existing airbag type rapid sealing device uses a foot-operated air pump to inflate the airbag during use.

At this time, the sealing curtain is wrapped on the airbag arch frame, thereby solving the problem that the existing sealing curtain and the airbag arch frame are connected by hooks, which is very laborious during the hooking process and may also cause unhooking.
