Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figures 1 to 4 , the utility model provides a technical solution:

[0023] A highly flexible composite pipe comprises a first pipe 1 and a second pipe 2, wherein the adjacent ends of the first pipe 1 and the second pipe 2 are fixedly connected with a first pipe 1 joint, the adjacent ends of the second pipe 2 and the first pipe 1 are fixedly connected with a second pipe 2 joint, and the first pipe 1 joint and the second pipe 2 joint are formed by a pipe heater;

[0024] The inner diameter of the first pipe 1 joint is equal to the outer diameter of the second pipe 2 joint, the inner wall of the first pipe 1 joint and the outer wall of the second pipe 2 joint are respectively formed with threaded areas by pipe heaters, and the two are threadedly connected and fixed by the threaded areas, and the first pipe 1 and the second pipe 2 have exactly the same structure.

[0025] The first pipe 1 includes a pipe inner layer 32 and a pipe outer layer 31 , an embedding groove 34 is provided between the pipe inner layer 32 and the pipe outer layer 31 , the embedding groove 34 is designed in a spiral structure, and an elastic strip 35 with a spiral structure is embedded and connected in the embedding groove 34 .

[0027] Working principle: During use, the two pipe ports are heated and plasticized at both ends of the pipes by the pipe heater at high temperature to form the first pipe 1 joint and the second pipe 2 joint. In the process of processing the pipe joints, the pipe heater will heat-melt the pipe body. At this time, the elastic strip 35 embedded in the pipe is raised to form a threaded area surface with the heated pipe surface. The pipe ports are heated by the expansion and contraction of the diameter at both ends of the pipe heater to match each other. After the first pipe 1 joint and the second pipe 2 joint are cooled, the first pipe 1 and the second pipe 2 are threadedly connected and fixed by the first pipe 1 joint and the second pipe 2 joint to form a stable connection interface, so that the subsequent pipes are not easy to fall off during use, thereby increasing the stability of the subsequent pipe connections.
