[0001] This utility model relates to the field of communication cable protection pipe technology, specifically a protection pipe for communication cables. Background Technology

[0002] Communication cable protection pipes are infrastructure used to protect and manage communication cables. Their main function is to prevent external physical damage and environmental factors from affecting the cables, ensuring stable transmission of communication signals. To facilitate the protection of communication cables, protection pipes are often used to cover their surfaces. Since the protection pipe is integrally molded and the cable is directly threaded through the inside of the protection pipe, when repairing the communication cable, the communication cable needs to be pulled out from one end of the protection pipe, and after the repair, the communication cable needs to be threaded back into the protection pipe. This operation method brings inconvenience to the maintenance personnel. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-8 As shown, a protective tube for communication cables includes a first arc-shaped tube 1, a second arc-shaped tube 3 hinged to the bottom of the first arc-shaped tube 1, a first extension block 4 fixedly connected to one side of the first arc-shaped tube 1, and a second extension block 5 fixedly connected to one side of the second arc-shaped tube 3. The bottom of the first extension block 4 and the top of the second extension block 5 are both provided with several threaded grooves 7. A rotating rod 18 is rotatably connected inside the first extension block 4, and several fourth bevel gears 19 are fixedly connected to the surface of the rotating rod 18. A third bevel gear 11 meshes with one side of each fourth bevel gear 19. A fixed post 10 is fixedly connected to the bottom of the gear 11. A square groove 16 is opened at the bottom of the fixed post 10. A square post 20 is slidably connected to the surface of the square groove 16. A bolt 13 is fixedly connected to the bottom of the square post 20. A rotating structure 9 is provided on the surface of the rotating rod 18. Several telescopic rods 14 are fixedly connected to the inner sides of the first arc-shaped tube 1 and the second arc-shaped tube 3. A spring 15 is sleeved on the surface of the telescopic rod 14. A pad 8 is fixedly connected to the other end of the telescopic rod 14. The two ends of the spring 15 are fixed to the inner side of the first arc-shaped tube 1 and the top of the pad 8, respectively.

[0023] The rotating structure 9 includes a second bevel gear 93, which is fixed to the surface of the rotating rod 18. A first bevel gear 92 meshes with one side of the second bevel gear 93. The size of the first bevel gear 92 is smaller than that of the second bevel gear 93. A rotating plate 91 is fixed to the top of the first bevel gear 92 via a rotating shaft. With the rotating structure 9, when the rotating plate 91 rotates, it will drive the first bevel gear 92 to rotate, and at the same time drive the second bevel gear 93 to rotate as well. This will drive the rotating rod 18, the second bevel gear 93, and the third bevel gear 11 to rotate, thus facilitating the application of force to rotate the rotating rod 18. At the same time, since the size of the first bevel gear 92 is smaller than that of the second bevel gear 93, it is easier for the operator to rotate the rotating rod 18, thus saving effort.

[0024] Both sides of the inner wall of the square groove 16 are provided with sliding grooves 17. The surface of the sliding groove 17 is slidably connected with a slider 2. The slider 2 is fixed to the top of both sides of the square column 20. Through the setting of the sliding groove 17 and the slider 2, when the square column 20 moves downward, the position of the square column 20 after moving can be limited.

[0025] The top of the first extension block 4 is provided with a circular groove 21, and the rotating plate 91 is located inside the circular groove 21. A cover plate 22 is hinged inside the circular groove 21. By setting the circular groove 21 and the cover plate 22, the circular groove 21 can be blocked when the rotating plate 91 is not in use, thereby preventing foreign objects from getting stuck on the rotating plate 91.

[0026] A protective pad 12 is fixedly connected to the inner side of the pad 8. The protective pad 12 is made of rubber. With the setting of the protective pad 12, the cable can be protected when it passes through the pipe, thereby avoiding wear on the surface of the cable.

[0027] Sealing gaskets 6 are provided on the inner sides of both ends of the first arc-shaped pipe 1 and the second arc-shaped pipe 3. By setting the sealing gaskets 6, when the first arc-shaped pipe 1 and the second arc-shaped pipe 3 are connected to other pipes, the sealing between the pipes can be increased, thereby preventing dust and moisture from entering.

[0028] Working principle: When installing the communication cable, the worker first places the cable inside the second arc-shaped tube 3. Then, the first arc-shaped tube 1 is flipped over to align with the second arc-shaped tube 3. After aligning, an external wrench is aligned with the rotating plate 91, which in turn drives the first bevel gear 92 to rotate. This rotation, in turn, causes the second bevel gear 93, the rotating rod 18, and the fourth bevel gear 19 to rotate. The rotation of the fourth bevel gear 19, in turn, causes the third bevel gear 11 and the fixed post 10 to rotate together. The square column 20 and bolt 13 are moved downwards, so that bolt 13 is screwed into the threaded groove 7, thereby fixing the first arc-shaped tube 1 and the second arc-shaped tube 3. During the fixing process, the elastic force of the spring 15 can keep the pad 8 in contact with the cable, thereby improving the subsequent fixing effect. When the cable needs to be repaired, the rotating plate 91 can be reversed by an external wrench, and the above operation can be repeated to remove the limit on the first arc-shaped tube 1 and the second arc-shaped tube 3, so as to facilitate the cable repair.
