[0017] like Figures 1 to 4 As shown, the utility model relates to a new type of high-pressure tube structure on a long-tube air respirator, including a high-pressure tube body 1, and a stainless steel inner tube 4 is fixedly provided inside the high-pressure tube body 1; the stainless steel inner tube 4 is passed through the interior of the high-pressure tube body 1 to enhance the toughness of the high-pressure tube body 1, improve the strength of the high-pressure tube body 1, and make it less likely to burst.

[0018] The high-pressure pipe body 1 includes an inner resin pipe 101, the outer side of the inner resin pipe 101 is wrapped with a braided winding layer 102, and the outer side of the braided winding layer 102 is wrapped with a protective layer 103; the inner resin pipe 101 can be a resin pipe, and the braided winding layer 102 braided with steel wire can improve the strength of the inner resin pipe 101, and the setting of the protective layer 103 can wrap the braided winding layer 102 inside, which is not easy to be damaged, and strengthens the integrity of the combination. In this way, the strength of the high-pressure pipe body 1 can be improved.

[0019] A clamping sleeve 2 is fixedly provided on the outer sides of both ends of the high-pressure pipe main body 1, a high-pressure pipe joint 3 is fixedly provided on the side end of the high-pressure pipe main body 1, and the side end of the high-pressure pipe joint 3 is inserted into the interior of the high-pressure pipe main body 1, and the outer wall of the stainless steel inner tube 4 is fitted and connected with the inner wall of the high-pressure pipe joint 3, and the stainless steel inner tube 4 and the high-pressure pipe joint 3 are fixed and sealed by laser welding; the design of the clamping sleeve 2 can further improve the strength of the connecting end of the high-pressure pipe main body 1, and limit the pipe diameter of the side end of the high-pressure pipe main body 1 so that it is not easy to expand. The connection method in which the high-pressure pipe joint 3 is inserted into the interior of the high-pressure pipe main body 1 can improve the connection strength and is not easy to loosen and fall off. At the same time, the combination of the stainless steel inner tube 4 and the high-pressure pipe joint 3 can further improve the connection effect of the high-pressure pipe joint 3 and the high-pressure pipe main body 1. The laser welding process can improve the connection strength and connection sealing.

[0021] Working principle: This embodiment provides a new type of high-pressure tube structure on a long-tube air respirator. First, the high-pressure tube body 1 composed of an inner resin tube 101, a braided winding layer 102 and a protective layer 103 can improve its own strength. The addition of a clamping sleeve 2 and a high-pressure pipe joint 3 can further improve the strength of both ends of the high-pressure tube body 1, thereby improving the explosion-proof strength of the connecting end and improving the safety of use. The stainless steel inner tube 4 is passed through the high-pressure pipe joint 3 to the inside of the high-pressure tube body 1 to enhance the toughness of the high-pressure tube body 1. The connection with the high-pressure pipe joint 3 by welding can keep the penetration position fixed and is not easy to fall off. At the same time, the high-pressure pipe joint 3 can also be further limited to enhance the integrity of the overall connection. In this way, with the cooperation of the overall structure, the safety of use can be effectively improved.
