Multipurpose inflatable sheet

[0023] Such as figure 1 , 2 A kind of multi-purpose inflatable sheet shown in . The airbag body 1 is composed of two airbag sheets A1, B1, the edges of the airbag sheets A1, B1 are hot-melted and pressed together, the periphery of the airbag body 1 is fixed with a first connector 2, and the surface of the airbag body 1 There are multiple welding lines on the top, and the welding lines are two airbag sheets A1 and B1 that are hot-melted and pressed together, so that the airbag body 1 is divided into multiple sub-cavities, and the adjacent sub-cavities are connected end to end. into a continuous cavity, such as figure 1 As shown, from the right side, the upper end of the odd-numbered welding lines 11 is connected with the upper edge of the airbag body 1, and a certain distance is left between the lower end and the lower edge of the airbag body 1, and the upper end of the even-numbered welding lines 12 is connected with the airbag body 1. There is a certain distance between th...

[0030] Such as figure 1 , 4 , a kind of multipurpose inflatable sheet shown in 5, comprises airbag body 1, connector, and described airbag body 1 is rectangular structure, and described airbag body 1 interior has cavity 13, and described airbag body 1 is made of two airbag sheets A1 , B1, the edges of the airbag sheets A1, B1 are hot-melted and pressed together, the periphery of the airbag body 1 is fixed with a first connector 2, and the surface of the airbag body 1 has a plurality of welding lines, and the welding lines are the The two airbag sheets A1 and B1 are pressed together by hot-melt pressure, so that the airbag body 1 is divided into multiple sub-cavities, and the adjacent sub-cavities are connected from end to end to form a continuous cavity, such as figure 1 As shown, from the right side, the upper end of the odd-numbered welding lines 11 is connected with the upper edge of the airbag body 1, and a certain distance is left between the lower end and the lower edge...

[0034] Such as Figure 6 A multi-purpose inflatable sheet shown includes an airbag body 5, a first connector 2, and a second connector 3. The airbag body 5 is circular or oval, and the airbag body 1 has a cavity inside. The airbag body 5 is composed of two airbag sheets, the edges of the airbag sheets are hot-melted and pressed together, the periphery of the airbag body 5 is fixed with a first connector 2, and a continuous spiral curve is welded on the surface of the airbag body 5 Line 51, spiral curve welding line 51 is a welding line formed by pressing two airbag sheets together through hot-melt pressure, so that a continuous cavity is formed in the airbag body 5, such as Figure 4 As shown, two ends of the continuous cavity are provided with an inflation and deflation port 4 respectively, and the second connecting piece 3 is fixed at the helical curve welding lines 51 on the upper surface and the lower surface of the airbag body 5 .
