[0028] Reference Figure 1 As shown, the utility model provides a technical solution: a high-strength variable-diameter corrugated pipe, comprising a pipe body 1, a reinforcement structure 2 is provided on the outer side of the pipe body 1, and a support structure 3 is provided on the lower surface of the pipe body 1.

[0029] The following describes in detail the specific configuration and function of the reinforcement structure 2 and the support structure 3.

[0030] Reference Figure 1-Figure 3As shown, in this embodiment, the reinforcement structure 2 includes a retaining ring 201 that fits over the outer surface of the tube body 1. Two reinforcement strips 202 are fixedly connected to the ends of the retaining ring 201. First bolts 205 are threadedly connected to the interior of the reinforcement strips 202. Several second bolts 210 are evenly threadedly connected to the interior of the retaining ring 201. The presence of the reinforcement structure 2 at the diameter-changing position of the tube body 1 improves the stability of the tube body 1 during use, preventing it from buckling inward at this location. This improves the durability of the tube body 1 and extends its service life. A first slide 204 is slidably connected to the interior of the reinforcement strip 202. A first retaining block 203 is fixedly connected to the end of the first slide 204. A first bolt 205 is internally rotatably connected to the first retaining block 203. Several second slides 208, arranged in pairs, are slidably connected to the interior of the tube body 1. The other ends of the two second slides 208 are fixedly connected to second retaining blocks 207. Second bolts 210 are internally rotatably connected to the second retaining blocks 207. Rotating the second bolt 210 pushes the second stopper 207 toward the side closer to the pipe body 1. The second slide 208 moves within the stop ring 201, limiting the movement of the second stopper 207. This facilitates securing the stop ring 201 on the outside of the pipe. Rotating the first bolt 205 then drives the first stopper 203 to move. The first slide 204 slides within the reinforcement strip 202, limiting the movement of the first stopper 203. This allows reinforcement of the variable diameter position of the pipe body 1. Both the first stopper 203 and the second stopper 207 have V-shaped grooves on their surfaces. The V-shaped grooves on the first and second stopper 203 and 207 enhance the tightness of the clamping of the outer side of the circular pipe. A first anti-slip pad 206 and a second anti-slip pad 209 are glued to the inner sides of the V-shaped grooves on the first and second stopper 203 and 207, respectively. By providing the first anti-slip pad 206 and the second anti-slip pad 209 , the friction between the first limiting block 203 , the second limiting block 207 and the pipe is increased, thereby improving the stability of clamping the pipe body 1 .

[0031] Reference Figure 1 and Figure 4As shown, specifically, the support structure 3 includes a support plate 31 fixedly connected to the lower surface of the tube body 1. A support frame 32 is slidably connected to the lower side of the support plate 31. The support frame 32 has a "human" structure. The "human" structure of the support frame 32 improves the stability of the support of the tube body 1. A fixing rod 35 is fixedly connected to the surface of the support frame 32. An insert plate 33 is slidably connected to the outer side of the fixing rod 35. The insert plate 33 slides through the support frame 32. The surface of the support plate 31 is provided with a plurality of insertion holes 37, the size of which matches the size of the insert plates 33. The insert plates 33 are inserted into the inner side of the insertion holes 37, which can achieve the locking function between the support frame 32 and the support plate 31 after movement. The surface of the fixing rod 35 is covered with a spring 36, the two ends of which are fixedly connected to the insert plate 33 and the circular block 34 respectively. The insert plate 33 is inserted into the inner side of the insertion hole 37 due to the elastic force of the spring 36.

[0032] The working principle is to put the limiting ring 201 on the outside of the pipe body 1, and put the limiting ring 201 on the outside of the pipe body 1 with a larger diameter, then rotate the second bolt 210, the second bolt 210 will push the second limiting block 207 to move toward the side close to the pipe body 1, wherein the second slide 208 moves inside the limiting ring 201 to limit the moving direction of the second limiting block 207, which is convenient for fixing the limiting ring 201 on the outside of the pipeline. At this time, rotate the first bolt 205, the first bolt 205 will drive the first limiting block 203 to move, wherein the first slide 204 slides inside the reinforcement bar 202, which limits the moving direction of the first limiting block 203. The pipe body 1 can be reinforced at the variable diameter position by providing a V-shaped groove on the surface of the first limit block 203 and the second limit block 207, thereby improving the tightness of clamping the outer side of the circular pipe. The first anti-slip pad 206 and the second anti-slip pad 209 are provided to increase the friction between the first limit block 203, the second limit block 207 and the pipe, thereby improving the stability of clamping the pipe body 1. The reinforcement structure 2 is provided, and the stability of the pipe body 1 at the variable diameter position is improved by providing a reinforcement structure 2. The phenomenon of inward folding of the pipe body 1 at the variable diameter position is avoided, thereby improving the use strength of the pipe body 1 and extending the service life of the pipe body 1.

[0033] When the support frame 32 is in the state of being pressed down, the support frame 32 of the support plate 31 is pressed down, and the support frame 32 of the support plate 31 is pressed down.
