The gear stage 905 is slidably installed inside the slide 903, and the bottom of the gear stage 905 extends to the inside of the through hole 904. The slider 907 is connected to one end of the slide 903 close to the arc ring 901, the rocker 909 is rotatably installed on the periphery of the main shaft 902, and the slider 907 passes through the rocker 909. The clamping mechanism 8 includes a semicircular ring 801 and a rack 802. The semicircular ring 801 is sleeved on the periphery of the sleeve tube 7, and the side of the clamping mechanism 8 is installed with a rack 802 corresponding to the position of the through hole 904.

[0023] Based on the above-mentioned structural setting, the HDPE winding structure wall pipe is composed of an inner base pipe 1 and an isolation pipe 2 sleeved on the outer periphery of the inner base pipe 1, and a spiral winding pipe 5 is wound around the outer periphery of the isolation pipe 2, a butt pipe 6 is installed on one side of the inner base pipe 1, and a sleeve pipe 7 is connected to the other side of the inner base pipe 1, and a stretching mechanism 9 is detachably installed on the outer periphery of the butt pipe 6, and a detachable clamping mechanism 8 is installed on the outer periphery of the sleeve pipe 7, wherein the winding pipe 5 is spirally wound around the outer periphery of the isolation pipe 2, which can increase the overall deformation resistance and corrosion resistance of the device, and guide the sewage through the inner base pipe 1, and the stretching mechanism 9 and the clamping mechanism 8 are both detachable structures, which are assembled and used according to needs during use, and the butt pipe 6 and The outer periphery of the sleeve tube 7 is equipped with a convex ring compatible with the stretching mechanism 9 and the clamping mechanism 8. The butt joint 6 and the sleeve tube 7 can be used to realize the splicing and disassembly of the pipelines. Specifically, during the working process, after the pipeline to be butted is moved to the specified position, the sleeve tube 7 is butted with the butt joint 6. When the inserting tube 10 on the butt joint 6 is not completely inserted into the sleeve tube 7, the stretching mechanism 9 is assembled on the outer periphery of the butt joint 6 through the arc ring 901, and the clamping mechanism 8 is assembled on the outer periphery of the sleeve tube 7 through the semicircular ring 801. After assembly, the rack 802 is inserted into the through hole 904. During the insertion process of the rack 802, the inclined surface of the gear stage 905 contacts, so the gear stage 905 It will automatically shrink as the rack 802 is inserted. When the rack 802 cannot move and the cannula 10 is not completely inserted into the sleeve tube 7, the user swings the swing rod 909 to one side. During the swinging process of the swing rod 909, the slider 907 drives the slide 903 to rotate around the main shaft 902. During the rotation of the slide 903, the back of the gear table 905 drives the rack 802 to move to the other side. The distance that the rack 802 moves each time is related to the size of the through hole 904 and the maximum rotation range of the slide 903. After the rack 802 moves, the swing rod 909 is rotated in the opposite direction. The rotation process of the swing rod 909 causes the gear table 905 to move from one position on the rack 802 to another position, and so on. After the insertion tube 10 is fully inserted into the sleeve tube 7, the operation is stopped. By changing the positions of the clamping mechanism 8 and the stretching mechanism 9 on the periphery of the sleeve tube 7 and the butt joint tube 6, the butt joint tube 6 and the sleeve tube 7 that have been spliced ​​can be easily disassembled by cooperating with each other. The HDPE winding structural wall tube is equipped with a clamping mechanism 8 and a stretching mechanism 9 that cooperate with each other. The principle of lever can realize the splicing and disassembly of pipes more labor-savingly, so that users can install and use the device conveniently. By connecting the inner steel ring 3 and the winding tube 5 through the connecting bolt 4, the stability between the winding tube 5 and the inner base tube 1 can be increased during use, while the overall pressure resistance and deformation resistance of the device can be improved.

[0024] Furthermore, a plug 10 is installed on one side of the butt joint pipe 6, and a clamp ring surrounds the outer periphery of the plug 10. A clamping groove 11 adapted to the plug 10 is provided inside the sleeve pipe 7. The vertical surface of the plug 10 is trapezoidal, and the clamp ring surrounds the outer periphery of the plug 10. When in use, by inserting the plug 10 into the sleeve pipe 7, the clamp ring on the outer periphery of the plug 10 overlaps with the clamping groove 11, which can increase the tightness between the butt joint pipe 6 and the sleeve pipe 7 and prevent them from falling off.

[0025] Furthermore, the stretching mechanism 9 also includes a spring 906. An inner groove is provided inside the slide 903 to meet the movement of the gear table 905. The top of the gear table 905 is connected to the inner groove via the spring 906. After the gear table 905 enters the inner groove due to the swing of the swing rod 909, the spring 906 is squeezed. Therefore, when the gear table 905 is not pushed by the rack 802, the spring 906 can quickly push the gear table 905 down, so that the gear table 905 is meshed with the top of the rack 802 again.

[0026] Furthermore, the stretching mechanism 9 further includes a slide groove 908, the interior of the swing rod 909 is provided with a slide groove 908 adapted to the slider 907, and the end of the slider 907 extending out of the slide groove 908 is provided with a cap having a diameter larger than that of the slider 907. The slide groove 908 can guide and limit the moving track of the slider 907 during use, thereby limiting the swing range of the swing rod 909, and the cap can prevent the slider 907 from falling off from the inside of the slide groove 908 without affecting the sliding of the slider 907 in the slide groove 908.

[0027] Furthermore, a right-angled triangular tooth is installed at the bottom of the gear stand 905, and a right-angled triangular tooth corresponding to the gear stand 905 is installed at the top of the rack 802. The right-angled triangular tooth can increase the force-bearing surface between the gear stand 905 and the rack 802 during use.

[0028] Furthermore, a plurality of inner steel rings 3 are evenly spaced inside the inner base pipe 1, and the inner steel rings 3 are connected to the inner steel rings 3 through connecting bolts 4. The inner steel rings 3 are located in the inner wall of the inner base pipe 1, and the inner steel rings 3 and the winding pipe 5 are connected through connecting bolts 4, which can increase the stability between the winding pipe 5 and the inner base pipe 1 during use, and improve the overall pressure resistance and deformation resistance of the device.
