Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The following working principles, detailed connecting means thereof, and the following main descriptions of the working principles and processes are well known in the art, and will be referred to by those skilled in the art for the specific connection and operation sequence of the components in this application.

The first embodiment is as follows: as can be seen from fig. 1-2, an MPP cable protection tube convenient for inserting a cable comprises a tube body 1, wherein a convex block 4 is fixedly connected to the inner wall of the tube body 1, the convex block 4 is clamped with a groove on the outer side of a plastic ring 5, so that the whole is tight, a stop block 8 is fixedly connected to one end of the convex block 4, one side of the stop block 8 is fixedly connected with the inner wall of the tube body 1, the outer wall of the convex block 4 is movably connected with the plastic ring 5, two ends of the plastic ring 5 are attached to each other, a plurality of circular grooves 6 are processed on the inner wall of the plastic ring 5, balls 7 are arranged inside the circular grooves 6, and the balls 7 cannot roll out of the circular grooves 6;

in the specific implementation process, it is worth particularly pointing out that the rapid positioning, installation and disassembly of the plastic ring 5 are realized through the matching among the convex block 4, the plastic ring 5 and the circular groove 6, compared with the traditional insertion mechanism, the cost is saved, and the problems that although the rapid insertion is realized during the work of the existing protection tube, the insertion mechanism and the protection tube are integrally formed, the insertion mechanism cannot be disassembled, and the use cost is increased during the actual manufacture are solved;

furthermore, the plurality of balls 7 are distributed in an annular shape at equal intervals by taking the center of the pipe body 1 as a reference;

in the specific implementation process, it is worth particularly pointing out that the balls 7 are distributed in an annular and equidistant manner by taking the center of the pipe body 1 as a reference, so that the stability during insertion can be ensured, the cable is positioned at the center, and the deviation is avoided;

further, an MPP layer 2 and a protective layer 3 are arranged inside the pipe body 1;

in the specific implementation process, it is worth particularly pointing out that the main material of the protective layer 3 is ultra-high molecular weight polyethylene, which is a linear thermoplastic engineering plastic with excellent comprehensive performance and is a high molecular compound, and has super wear resistance, self-lubricity, high strength, stable chemical property and strong aging resistance, and can play a good role in protecting the internal cables;

specifically, when using this MPP cable protection pipe of being convenient for to alternate cable, the user can be earlier with 5 joints of plastics ring on fixture block 4, then promote to inside, make it support tightly with dog 8, alright carry out normal cable work that alternates this moment, the cable alternates and accomplishes the back, the user can be at the gap pulling plastics ring 5 between plastics ring 5 and cable, takes plastics ring 5 out, then breaks away from plastics ring 5 off with the fingers and thumb, makes it break away from the cable and takes out and use next time.

Example two: as can be seen from fig. 1 and 3, a metal ring 9 is arranged on the inner side of the pipe body 1, bolts 10 are connected to the upper and lower sides of the metal ring 9 through threads, and fixing parts 11 are mounted on the inner sides of the two bolts 10;

in the specific implementation process, it is worth particularly pointing out that through the cooperation among the bolt 10, the fixing member 11 and the rubber pad 12, the positioning of the cable after the insertion is realized, the movement in the connection process is avoided, the whole body is more stable, and the operation of a constructor is convenient;

further, rubber pads 12 are mounted on the inner sides of the two fixing pieces 11;

in the specific implementation process, it is worth particularly pointing out that the rubber pad 12 can be tightly attached to the cable through elastic deformation, so that the stability is further improved;

specifically, on the basis of the first embodiment, after the cable is inserted, the user can rotate the bolts 10 on both sides, and the bolts 10 can drive the rubber pad 12 to abut against the cable when rotating, so as to prevent movement during connection, thereby facilitating the operation of a constructor.
