[0038] The first air cushion 210 is arranged horizontally to provide horizontal support or cushioning; the second air cushion 220 is arranged vertically, and its upper part extends to the surface of the first air cushion 210, which not only increases the cushioning capacity in the vertical direction, but also enhances the overall stability and sealing by extending to the surface of the first air cushion 210. It provides all-round cushioning protection and sealing effect. The air cushion device has a simple structure, is easy to install, and is easy to maintain and replace.

[0039] In one embodiment of the utility model, the first air cushion 210 and the second air cushion 220 are connected by an air guide pipe so that the internal pressure is kept consistent. The first air cushion 210 is connected to an inflation pipe, one end of which is connected to the inflation port of an air pump, one end of which is installed with a one-way air inlet valve, and the first air cushion 210 is installed with a pressure relief valve;
