And then changing an inflation path, inflating towards the air ports A101 of the diaphragm 3 and the outer membrane 1 to achieve the full air of the air space 6 until the diaphragm 3 and the inner membrane 2 are completely attached, wherein the air density of the air space 6 is higher than that of the small air containing space 8, finally, each vent hole 202 is blocked by the expanded diaphragm 3, each air containing space is independent and is not communicated with each other, and the whole air arch door is formed in an inflated mode.

The whole filling formed product is not provided with the two bases 4 for positioning, and the whole appearance can be filled to the two ends of the product for contact. Because the air receiving space 6 is substantially constant in length after forming, and the area where the air receiving space is located is reduced in overall length extension due to the provision of more heat-seal fusion zones 22, as in the case of the express crash air bags, inflated air bags and uninflated air bags of the prior art, the external dimensions are different. Finally, the air containing space 6 is arranged at the periphery of the whole product, the whole appearance is rolled into a round shape, and therefore two bases 4 are required to be arranged and positioned into an arch shape.

Referring to fig. 1 and 20, the base is formed by fixing a base plate 401 and a convex column 402, the base plate 401 is a disk, the diameter of the base plate 401 is the same as that of the cylinder membrane, so as to ensure that the gas in the hollow part 23 of the gas arch door overflows as little as possible, and the end surface of the base plate 401, which is in contact with the ground, has wear resistance. The convex column 402 is shaped like a cylinder and mainly has the functions of installation, fixation and positioning for being arranged in the hollow part of the gas arch door. The whole base 4 can be made into a hollow body so as to be convenient for containing water or sand. And pouring out the water and the sand for storage after use. The base 4 has three functions, 1, plays the fashioned locate function of arched door, 2, its both ends of protection gas arched door avoid with the damaged influence of ground friction, 3, make the air tightness of gas arched door cavity portion 23 obtain guaranteeing, the gas in cavity portion 23 also has the effect of indirect auxiliary stay door arch.

The hollow part 23 of the arch body of the air arch door can select whether to install the landscape lamp according to the requirement, the landscape lamp can better set off the advertisement theme and enhance the visual effect, and the landscape lamp is not arranged when the landscape lamp is not needed.
