[0002] CPVC electric pipes are made of PVC-C resin with excellent heat resistance and insulation properties as the main material. CPVC products are recognized as green and environmentally friendly products, and their excellent physical and chemical properties are increasingly valued by the industry.

[0003] CPVC power pipes are hard straight solid wall pipes, so after extrusion molding, they are prone to rupture if subjected to large external extrusion pressure. In addition, when splicing power pipes, they are mostly threaded splicing, and the power pipes need to be rotated to complete the docking, which is inconvenient to operate. Utility Model Content

[0004] The purpose of the utility model is to provide a CPVC power cable protection tube with a polygonal structure, which has a simple structure, is easy to produce, and has extremely strong pressure resistance.

It has strong practicality and is suitable for promotion.

[0005] The utility model provides the following technical scheme: a CPVC power cable protection tube with a polygonal structure, comprising a protection tube body, the cross-section of the protection tube body is a regular hexagon, an inner tube is sleeved inside the protection tube body, a circular array of support arms are fixedly provided on the outer wall of the inner tube corresponding to the edge of the protection tube body, a protruding tube extending outward is fixedly provided on the front butt tube at the front end of the protection tube body, the shape and size of the opening of the rear butt tube at the rear end of the protection tube body match the protruding tube, each edge of the front butt tube is provided with a concave groove on the outer wall of the protection tube body, an elastic clip is fixedly provided at the front section of the rear butt tube corresponding to the groove, a symmetrical L-shaped hook plate is fixedly provided on the edge of each side wall of the rear butt tube, and a hook groove is provided on the front end surface of the front butt tube corresponding to the L-shaped hook plate.

[0006] Preferably, the protection tube body, the built-in tube and the support arm are all PVC-C resin pipes.

[0007] Preferably, the elastic clip is two adjacent elastic strips with a gap in between, symmetrical bosses are fixed on both sides of the elastic clip, and limiting grooves of the inner groove are provided at the bosses on both side walls of the slot, and the side of the boss away from the slot is a plane facing the slot.

[0008] Preferably, when the protection tube main bodies are assembled on the side wall, the front and rear ends of the two protection tube main bodies are opposite.

[0009] The beneficial effects of the utility model are as follows: the structure is simple, the production is convenient, the pressure resistance is extremely strong, and the protection tube is a polygonal structure, the side wall of which can be connected and fixed, the front and rear ends of the pipeline are also convenient to connect, and the practicability is strong, as follows:

[0010] (1) The utility model is provided with a protective pipe body, which is a polygonal pipe, and an inner pipe is laid inside the polygonal pipe. A support arm is provided between the inner pipe and the polygonal pipe to form a stable structure. When subjected to pressure, the protective pipe body and the inner pipe are supported together, and the most vulnerable edges of the polygonal pipe are fixed and supported by the support arm, making the pipe more resistant to pressure.

[0011] (2) The utility model is provided with a front butt joint pipe and a rear butt joint pipe. When the protective tube bodies are spliced, if multiple pipes need to be bundled together, the front and rear ends of the two protective tube bodies are placed oppositely, and the L-shaped hook plates on the sides are aligned with the hook grooves. After the two protective tube bodies are aligned, the L-shaped hook plates at both ends of the protective tube bodies are clamped in the hook grooves, so that the side walls of the two protective tube bodies are connected. At this time, the front and rear protective tube bodies are butt jointed again. When butt jointing, the rear butt joint pipe is aligned with the protruding tube of the front butt joint pipe and inserted. During the insertion process, the elastic clip strip is squeezed by the clip groove, causing it to undergo elastic deformation. The two elastic strips gather toward the middle. When the boss on the two elastic strips reaches the limit groove, the boss pops into the limit groove, and the elastic clip strip is restored and fixed in the clip groove. The butt joint is completed, and the rear butt joint pipe is pressed against the L-shaped hook plate in the hook groove, so that the L-shaped hook plate cannot slide, thereby fixing the protective tube body of the side wall.
