[0002] CPVC is a new type of engineering plastics with broad application prospect, which is made by chlorination modification of polyvinyl chloride (PVC) resin. CPVC is mainly used for producing plate, bar, pipe conveying hot water and corrosive medium, which can maintain sufficient strength when the temperature is not more than 100°C, and can be used for a long time under high internal pressure. The weight of CPVC is 1 / 6 of brass and 1 / 5 of steel, and it has very low thermal conductivity, so the pipeline made of CPVC is light in weight and good in heat insulation performance, and does not need to be insulated. According to the application number CN212114629U, a porous polyvinyl chloride CPVC communication pipe is provided, which has a cable arrangement assembly arranged in the protective pipe body. The plurality of cable arrangement pipes in the cable arrangement assembly can uniformly separate and erect the plurality of cables in the protective pipe body, prevent the plurality of cables from gathering together and heating, protect the cables, and when the cables burn in a fire, the plurality of cables are separated and will not cause the short circuit of the cables. However, the internal space of the communication pipe is fixed, and if more cables and cables of various diameters need to be limited, the communication pipe cannot meet the installation and limiting needs.

[0005] Preferably, the outer side of the first screw is screw-connected with the first threaded groove.

[0006] Preferably, the other end of the CPVC protective pipe and the end part of the installation frame are fixedly connected with a second threaded block, a second screw is screw-connected in the second threaded block, a second threaded groove is formed in one end of the installation frame and at the end part of the second screw, and one end of the second screw extends into the second threaded groove and is screw-connected with the second threaded groove.

[0007] Preferably, the outer side of the CPVC protective pipe is provided with a wear-resistant sleeve.

[0008] Preferably, both the first screw and the second screw are made of non-metallic insulating materials.

[0009] Preferably, the mounting frames cooperate with each other.

[0010] This utility model provides a high-strength porous CPVC cable sheath, which has the following advantages:

[0011] 1. This high-strength, multi-hole CPVC cable sheath is equipped with mounting frames, protective fillers, and through holes. Depending on the number of cables to be sheathed, a set of mounting frames corresponding to the number of cables is selected. The total number of through holes inside the four mounting frames corresponds to the number of cables. The protective filler is inserted into the CPVC protective tube through one end, so that the first threaded block is located at one end of the CPVC protective tube, and the second threaded block is located on the outside of one end of the mounting frame. Then, one end of the second screw is screwed into the second threaded groove, and one end of the first screw is screwed into the first threaded groove, fixing the mounting frame inside the CPVC protective tube. This allows for the selection of mounting frames with an appropriate number of through holes for cable protection.

[0012] 2. This high-strength porous CPVC cable sheath tube, through the cooperation of the second threaded block, the second screw and the second threaded groove, can fix one end of the mounting frame, and through the first threaded block, the first screw and the first threaded groove, can fix the other end of the mounting frame, thereby limiting the two ends of the mounting frame and fixing the mounting frame inside the CPVC protective tube.
