Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: a heat dissipation type MPP cable protection tube comprises an MPP tube body 1, a cable 2, a heat dissipation plate 3, a first connection tube 4, a spring 5, a second connection tube 6, a movable block 7 and a roller 8, wherein an arc-shaped groove is formed in one section of the outer wall of the MPP tube body 1 close to a tube opening, a through hole for inserting one end of the heat dissipation plate 3 is formed in the arc-shaped groove, the outer end of the heat dissipation plate 3 is located inside the arc-shaped groove, a groove is formed in the inner wall of the MPP tube body 1, the groove wall is connected with the movable block 7 through the spring 5, the inner end face of the movable block 7 is attached to an arc-shaped structure on the outer wall of the cable 2, the MPP tube body 1 acts on the movable block 7 through the spring 5 to form an elastic structure with the movable block 7, the cable 2 can be elastically extruded between the included angle of the movable block 7 and the heat dissipation plate 3, the position of the, the other end of the heat dissipation plate 3 is inserted in the first connection pipe 4, part of the temperature absorbed by the heat dissipation plate 3 can be collected in the first connection pipe 4 so as to be conveniently and intensively dissipated, through holes are arranged at the middle ends of the MPP pipe body 1 and the first connection pipe 4, the through holes are embedded with the second connection pipes 6 which are communicated, the second connection pipes 6 are uniformly distributed in a cross-shaped structure, the position of the second connection pipes 6 improves the heat dissipation efficiency of the first connection pipe 4, the heat dissipation effect of the MPP pipe body is further improved, the heat dissipation plate 3 is uniformly distributed in the cross-shaped structure, cables 2 are inserted between the included angles of the 2 heat dissipation plates 3, a movable block 7 is arranged at the other side of each cable 2, a groove is arranged at one side of the movable block 7, a rolling shaft 8 is inserted and connected in the groove through a rotating shaft, the rolling shaft 8 is contacted with the outer wall of the cable 2, and the rolling shaft 8, the working efficiency is improved, and the friction damage of the cable 2 is avoided.
