Embodiment Construction
[0027] The application will be described in further detail below in conjunction with the accompanying drawings.
[0028] refer to figure 1 and figure 2 , the embodiment of the present application discloses an inflatable sleeve, the sleeve is an annular tubular structure, and the wall of the sleeve is a composite layer structure. The composite layer structure includes an inflatable layer 1 , a first elastic layer 10 , a filling layer 2 , a second elastic layer 11 , and a shaping layer 3 arranged sequentially from inside to outside along the radial direction of the sleeve. The inflatable layer 1 is a fiber layer made of fiber material. In this embodiment, the inflatable layer 1 is preferably a glass fiber layer, and the glass fiber has relatively high tensile strength and good heat resistance. The air-expansion layer 1 is used for interference fit on the air-expansion shaft. When the air-expansion shaft is inserted into the air-expansion layer 1 of the sleeve, the air-expansi...
