[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. 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.

[0023] See also Figures 1 to 3 , the utility model provides a technical solution:

[0024] A high temperature resistant composite pipe, comprising a pipe 1 and a pipe 2, characterized in that: corresponding positions of the inner walls of the adjacent ends of the pipe openings of the pipe 1 and the pipe 2 are fixedly connected with inner clamp rings 3;

[0025] A connecting piece is provided between the pipeline 1 and the pipeline 2;

[0026] The connecting member comprises an inner sleeve 6 and an outer sleeve 4, and a barrier ring 5 is integrally fixedly connected between the inner sleeve 6 and the outer sleeve 4;

[0027] The outer surfaces of the adjacent ends of the pipe 1 and the pipe 2 2 are threaded surface 1 8, and the inner wall of the outer sleeve 4 corresponding to the threaded surface is threaded surface 2 9;

[0028] An outer clamping ring 7 is symmetrically fixedly connected to the outer portion of the inner sleeve 6 .

[0029] The outer surfaces of both sides of the barrier ring 5 are sawtooth ends 11, and the sawtooth ends 11 are composed of a plurality of teeth distributed in an annular shape at equal distances on the surface of the barrier ring 5, and rubber pads are fixed between adjacent teeth.

[0030] The adjacent end faces of the pipe 1 and the pipe 2 2 are sawtooth ends 10 , and the sawtooth ends 10 and 11 have the same structure, and the tooth directions of the sawtooth ends 10 and 11 are opposite.

[0031] Working principle: When working, firstly, the connector is sleeved on the outside of pipe 1 and pipe 2, respectively. At this time, pipe 1 and pipe 2 are both located between the inner sleeve 6 and the outer sleeve 4 in the connector. Then the user rotates the connector clockwise. At this time, the inner threaded surface 29 of the outer sleeve 4 is threadedly connected with the outer threaded surface 8 of pipe 1 and pipe 2, so as to realize the combination and fixation of the connector with pipe 1 and pipe 2. With the relative displacement of the rotating connector, the outer clamping ring 7 squeezes the inner clamping ring 3, and the outer clamping ring 7 is displaced. To the other side of the inner retaining ring 3, the two are squeezed against each other and fixed, thereby increasing the fixing effect of the connector and pipe 1 and pipe 2. At the same time, the serrated end 10 of the adjacent end faces of pipe 1 and pipe 2 engages with the serrated end 2 11 on both sides of the barrier ring 5. Since the tooth ends of the two are opposite, the connector can only be twisted clockwise and fixed counterclockwise during use through the engagement of the teeth of the serrated end 10 and the serrated end 2 11, so that the connector will not loosen.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
