[0001] This utility model relates to the field of sheathed pipe technology, and in particular to a high-strength modified polyvinyl chloride sheathed pipe. Background Technology
[0002] Sheathed conduits are an essential structure in power communication processes. Based on polyvinyl chloride (PVC) with the addition of special modifiers, they have high strength and can withstand external impacts and compression during construction and use. The smooth conduit wall reduces cable friction and protects the cable sheath. They also have good insulation and corrosion resistance, effectively ensuring the safe and stable operation of power communication lines.
[0003] Existing technologies often have the following drawbacks: When carrying out power construction, sheathing pipes are often buried underground to wrap around the cables for protection. Sheathing pipes are susceptible to external forces such as mechanical impacts. Traditional sheathing pipes have low strength, which often leads to cracking and deformation of the sheathing pipes under external forces, thereby damaging the internal cables.
[0004] Therefore, this utility model provides a high-strength modified polyvinyl chloride sheathed pipe. Utility Model Content

[0028] Reference Figure 1 As shown, this utility model provides a technical solution: a high-strength modified polyvinyl chloride sheathed pipe, including a pipe 1, a polyvinyl chloride layer 2 on the outside of the pipe 1, a reinforcing structure 3 on the outer surface of the polyvinyl chloride layer 2, and an auxiliary structure 4 on the surface of the metal ring 31.
[0029] The specific setup and function of its reinforcement structure 3 and auxiliary structure 4 will be discussed below.
[0030] Reference Figures 1-3As shown in this embodiment: the reinforcing structure 3 includes several metal rings 31 that slide around the outside of the polyvinyl chloride layer 2, and an elastic strip 32 is bonded to the outside of the polyvinyl chloride layer 2. By setting up the reinforcing structure 3, the position of the metal rings 31 can be flexibly adjusted according to usage requirements, and the local reinforcement of the pipeline 1 can be stably strengthened according to usage requirements, maximizing the strength of the sheathed pipe. A guide groove 33 is provided on the inner side of the metal rings 31, and the guide groove 33 is slidably connected to the outer side of the elastic strip 32. The elastic strip 32 facilitates the guiding of the metal rings 31. A limiting block 34 is fixedly connected to the end of the metal rings 31, and a slider 35 is slidably connected to the surface of the limiting block 34. Several conical rods 38 are uniformly fixedly connected to the lower surface of the slider 35. Inserting the conical rods 38 into the corresponding elastic strips 32 can fix the position of the moved metal rings 31, preventing the metal rings 31 from sliding on the side wall of the pipeline 1. A connecting block 36 is fixedly connected to the side wall of the limiting block 34, and a first spring 37 is fixedly connected between the connecting block 36 and the slider 35. The slider 35 is driven by the elastic force of the first spring 37 on the connecting block 36 to insert the cone rod 38 into the elastic strip 32, which improves the stability of the cone rod 38 when inserted into the elastic strip 32.
[0031] Reference Figures 1-2 and Figure 4 As shown, specifically, the auxiliary structure 4 includes a pivot pin 42 fixedly connected to the side wall of the metal ring 31, and an arc-shaped plate 41 rotatably connected to the side wall of the pivot pin 42. By setting the auxiliary structure 4 and the arc-shaped plate 41 that can be flexibly rotated out and retracted, it is convenient to flexibly roll or stop the pipeline 1 according to the usage requirements, further improving the performance of the power pipeline 1. A positioning block 43 is fixedly connected to the surface of the arc-shaped plate 41, and an insert frame 45 is slidably connected inside the positioning block 43. Several insertion holes 46 are evenly opened on the side wall of the pivot pin 42, and the size of the insertion holes 46 is adapted to the size of the insert frame 45. First, the insert frame 45 inside the positioning block 43 is pulled out. After the insert frame 45 is pulled out, the arc-shaped plate 41 on the side wall of the pivot pin 42 can be rotated. When the arc-shaped plate 41 rotates out from the inside of the metal ring 31, the insert frame 45 is inserted into the inside of the corresponding insertion hole 46 on the pivot pin 42, which realizes the locking operation of the rotated arc-shaped plate 41. A spring is fixedly connected between the insert frame 45 and the positioning block 43. The insert frame 45 is inserted into the inner side of the corresponding insertion hole 46 on the pivot pin 42 by the elastic force of the second spring 44.
[0032] In terms of working principle, regarding the reinforcement structure 3, when the pipe is subjected to external pressure or impact, the metal ring 31 fitted on the outside of the PVC layer 2 plays a crucial supporting role. The guide groove 33 on the inner side of the metal ring 31 is slidably connected to the elastic strip 32, allowing for some adjustment of the relative position between the metal rings 31. This allows for adjustment of the position of the metal rings 31 according to actual usage needs, preventing local stress concentration that could lead to pipe breakage. Lifting the slider 35 moves the metal ring 31 to the appropriate position, and then inserting the cone rod 38 into the corresponding elastic strip 32, allows for adjustment of the position of the metal rings 31 after movement. The fixed position of the metal ring 31 prevents it from sliding on the side wall of the pipe 1, improving the stability of the metal ring 31 after it is moved. The slider 35 is driven by the elastic force of the first spring 37 on the connecting block 36 to insert the cone rod 38 into the elastic strip 32, improving the stability of the cone rod 38 when inserted into the elastic strip 32. By setting the reinforcement structure 3, it is convenient to flexibly adjust the position of the metal ring 31 according to the usage requirements, and to facilitate the stable reinforcement of local positions of the pipe 1 according to the usage requirements, thereby maximizing the strength of the sheathed pipe.
[0033] During the transportation or handling of the metal pipe 1, when it is necessary to stop the rolling operation of the pipe 1, first pull out the insert frame 45 inside the positioning block 43. After the insert frame 45 is pulled out, the arc plate 41 on the side wall of the pivot pin 42 can be rotated. When the arc plate 41 rotates out from the inside of the metal ring 31, the insert frame 45 is released. The insert frame 45 will be inserted into the inside of the corresponding insertion hole 46 on the pivot pin 42 by the elastic force of the second spring 44, which can realize the locking operation of the twisted arc plate 41. At this time, the arc plate 41 with the protruding structure can prevent the pipe 1 from rolling, which improves the stability of transporting a single pipe 1. Retracting the arc plate 41 can realize the normal rolling operation of the pipe 1. By setting the auxiliary structure 4 and the arc plate 41 that can be flexibly rotated out and retracted, it is convenient to flexibly roll or stop the pipe 1 according to the usage requirements, which further improves the performance of the power pipe 1.
