[0026] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] Please see Figures 1-4 ;

[0028] First embodiment:

[0029] This utility model provides a technical solution: a wear-resistant wire and cable protective sleeve, including a cable body 1, a protective device 2 for protecting the cable body 1, a fixing device 3 for securing the protective device 2, and a support device 4 for stabilizing the cable body 1.

[0030] The protective device 2 includes several sleeves 21, which are made of high-strength wear-resistant material and can effectively resist the friction and wear between the cable body 1 and the inner wall of the conduit during long-term use. Their surfaces are treated with a special process to reduce the coefficient of friction, thereby reducing the resistance of the cable body 1 during threading and preventing damage to the outer sheath caused by frequent pulling or vibration. Furthermore, the sleeves 21 have excellent anti-aging and anti-corrosion properties, maintaining stable mechanical strength and service life in complex environments for a long time, providing durable protection for the cable body 1 and ensuring the safety and reliability of the line operation.

[0031] The sleeve 21 is fitted outside the cable body 1. An installation groove 22 is provided inside the sleeve 21. A sealing strip 23 is fixedly connected to the bottom of the sleeve 21. A slot 25 is provided inside the sleeve 21. An installation block 24 is fixedly connected inside the sleeve 21.

[0032] Specifically, such as Figures 2-3 As shown, the size of the mounting groove 22 is slightly larger than the size of the sealing strip 23. One of the sealing strips 23 is fitted into the corresponding mounting groove 22. The size of the slot 25 is slightly larger than the size of the mounting block 24, and the mounting block 24 is fitted into the slot 25. A reinforcing layer 26 for improving the protective effect is fixedly connected inside the sleeve 21. The matching design of the mounting groove 22 and the sealing strip 23 in the sleeve 21 ensures a tight connection between the sleeves 21, effectively preventing external contaminants such as moisture and dust from entering the cable. The size of the mounting groove 22 is slightly larger than the sealing strip 23, which facilitates quick docking during installation. At the same time, the elastic material of the sealing strip 23 can adapt to thermal expansion and contraction in different environments, further improving the sealing performance. This design not only simplifies the installation process but also enhances the durability and protective effect of the protection device 2.

[0033] During operation, when a certain part of the sleeve 21 needs to be replaced, only the corresponding sleeve 21 needs to be removed, the new sleeve 21 is placed on the outside of the cable body 1, and then the mounting block 24 is inserted into the slot 25, and the mounting slot 22 is precisely aligned with the sealing strip 23 to complete the replacement. This design realizes the on-demand replacement of partial sleeves 21, avoids the need for overall replacement, significantly reduces maintenance costs, and improves resource utilization efficiency.

[0034] Second embodiment:

[0035] Specifically, such as Figure 4As shown, the fixing device 3 includes several circular sleeves 31, which are fitted over one of the tube sleeves 21. A fastening ring 32 is fitted over the circular sleeve 31. Both the fastening ring 32 and the tube sleeve 21 have openings, and two mounting plates 33 are installed at these openings. A threaded rod 34 passes through the two mounting plates 33, and a nut 35 is fitted over the threaded rod 34. The circular sleeves 31 and the fastening ring 32, through the cooperation of the threaded rod 34 and the nut 35, achieve a stable fixation of the tube sleeve 21. The fastening ring 32 adopts an adjustable thin-plate design, which can gradually reduce its inner diameter during installation, ensuring a tight fit between the tube sleeve 21 and the cable body 1. The mechanical connection of the threaded rod 34 and the nut 35 provides a high-strength fixing effect, while also facilitating disassembly and maintenance, significantly improving the reliability and service life of the protective sleeve.

[0036] The fastening ring 32 is a thin plate that is easy to adjust. The support device 4 includes a fixing seat 41, which is sleeved on the outside of the round sleeve 31 and the fastening ring 32. Two support legs 42 are fixedly connected inside the fixing seat 41. The support legs 42 are provided with limiting grooves 43 for easy fixing and limiting. The fixing seat 41 is sleeved on the outside of the round sleeve 31 and the fastening ring 32. Precise positioning and fixing are achieved through the limiting grooves 43 in the support legs 42. The design of the limiting grooves 43 not only enhances the stability of the support device 4, but also facilitates quick alignment during installation. The rigid structure of the support legs 42 can effectively distribute the weight and external stress of the cable body 1, prevent the protective sleeve from deforming or being damaged due to long-term stress, thereby improving the durability and safety of the overall structure.

[0037] During operation, after the sleeve 21 is installed, the fastening ring 32 and the round sleeve 31 are placed on the outside of the sleeve 21. Then, the threaded rod 34 is inserted into the mounting plate 33 and tightened with the nut 35. During the tightening process, the inner diameter of the round sleeve 31 and the fastening ring 32 gradually decreases, thereby achieving a stable fixation of the sleeve 21 and ensuring its reliability and stability during use.

[0038] The technical features of the above embodiments can be combined in any way (as long as there is no contradiction in the combination of these technical features). For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described; these embodiments not explicitly written should also be considered to be within the scope of this specification.
