They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0032] In the description of this utility model, "several" means one or more, "multiple" means two or more, "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number. If "first" or "second" is used in the description, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0033] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution. Example

[0034] like Figure 1 and Figure 2 The image shows an air column connector 100 of this embodiment, which is composed of two opposing air films 200, with the two air films 200 aligned vertically.

[0035] In this embodiment, the air film 200 has a layered structure, including a PE layer 202 and a PA layer 201. The PE layer 202 of both air films 200 is located on the inner side, and the PA layer 201 is located on the outer side.

[0036] The edges of the two air film sheets 200 are welded together in four places to form four welding areas 102. Since the PE layer 202 is located on the inner side, the PE layers are bonded together at the welding areas 102 using hot-press welding. This results in better stability at the weld and improved overall performance of the air column. The inner PE layer 202 has a lower melting point, allowing it to fuse quickly during hot pressing, facilitating manufacturing and processing. Simultaneously, the low-melting-point PE layer 202 also provides excellent sealing performance, effectively preventing gas leakage. The outer PA layer 201 has a higher melting point, remaining stable at high temperatures and exhibiting good tensile strength. The high-melting-point PA layer 201 enhances structural strength and stability, ensuring safety during use.

[0037] Connection ports 101 will be formed between adjacent welding areas 102. In this embodiment, there are four connection ports 101. The connection ports 101 are used to connect with the air column 300. The internal space between the two air films 200 is connected to all connection ports 101.

[0038] In this embodiment, the welding area 102 is a concave arc-shaped strip.

[0039] In another embodiment, the edge of the gas column connector 100 may have more welding areas 102, thereby forming more connection ports 101 to serve as five-way, six-way, eight-way, etc.

[0040] like Figures 3 to 5 As shown, this embodiment also discloses an inflatable support frame, which includes four air columns 300 and the air column connecting member 100. One end of each air column 300 is open, and the other end is closed. The open end of the air column 300 is welded to the connection port 101 of the air column connecting member 100. The air column 300 also has a layered structure, including a PE layer and a PA layer. The number of air columns 300 can be designed according to actual needs, and correspondingly, the number of connection ports 101 of the air column connecting member 100 is designed according to the number of air columns 300.

[0041] The structure that one end of the opening of the air column 300 is welded with the connecting port of the air column communication piece 100 can adopt the following form: the PE layer of the air column 300 is located at the inner side, the PA layer is located at the outer side, a connecting pipe 400 is arranged at the connecting position, the connecting pipe 400 is also a layered structure, including a PE layer and a PA layer, the PE layer of the connecting pipe 400 is located at the outer side, the PA layer is located at the inner side, the two ends of the connecting pipe 400 are respectively inserted into the opening of the air column 300 and the connecting port 101 of the air column communication piece 100, so that the PE layer of the connecting pipe 400 is in contact with the PE layer of the air column 300 and the PE layer at the connecting port 101, then the two ends of the connecting pipe 400 are respectively welded with the opening of the air column 300 and the connecting port 101 of the air column communication piece 100, the welding position forms a welding line 500, thereby completing the connection of the air column 300 and the air column communication piece 100.

[0042] The above embodiments of the utility model are not the limitation of the protection scope of the utility model, the implementation mode of the utility model is not limited to this, and other various forms of modification, replacement or change of the above structure of the utility model are made according to the ordinary technical knowledge and conventional means in the field, and all should fall within the protection scope of the utility model without departing from the above basic technical thought of the utility model.
