[0002] In the current field of cable technology, although various cable designs exist, they often prove insufficient under certain environmental conditions, particularly in terms of abrasion resistance and bending resistance. Traditional cable structures may not adequately meet the requirements for long-term stable operation in complex or harsh environments. For example, in industrial production lines, outdoor environments, or applications requiring frequent bending, cables may quickly fail due to wear or bending, leading to signal transmission interruptions or equipment malfunctions.

[0003] Given the shortcomings of existing technologies, there is an urgent market demand for a cable solution that offers superior abrasion resistance and bending resistance.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0021] Please see Figures 1-3 This utility model provides a technical solution:

[0022] A wear-resistant and bending-resistant cable includes a cable core 1, an outer sheath 2, and an intermediate layer 3 disposed between the cable core 1 and the outer sheath 2. The outer surface of the outer sheath 2 has multiple anti-slip protrusions 4 evenly distributed. The outer sheath 2 contains a plurality of circularly arranged anti-bending strips 5 distributed along the length of the cable, each consisting of several tightly fitted thin metal strips 50. Through a specific structural design, including the cable core 1, outer sheath 2, and intermediate layer 3, and the multiple evenly distributed anti-slip protrusions 4 on the outer sheath 2, as well as the plurality of circularly arranged anti-bending strips 5 inside, the wear resistance and bending resistance of the cable are improved. This cable structure not only enhances the cable's service life in complex environments but also improves its bending resistance, making the cable less prone to damage when bent or subjected to external forces.

[0023] In a preferred embodiment, the intermediate layer 3 comprises, from the inside out, an inner sheath 30, a buffer layer 31, a tensile layer 32, a thermal insulation layer 33, and a reinforcing layer 34. This multi-layered structure of the intermediate layer 3, comprising the inner sheath 30, buffer layer 31, tensile layer 32, thermal insulation layer 33, and reinforcing layer 34, further enhances the cable's abrasion resistance, tensile strength, thermal insulation, and overall strength, enabling the cable to operate stably under a wider range of environmental conditions.

[0024] In a preferred embodiment, the outer ring wall of the cable core 1 is fixedly connected to the inner wall of the inner sheath 30. The inner sheath 30 is made of rubber, and a metal mesh is provided in the interlayer of the inner sheath 30. The fixed connection between the cable core 1 and the inner sheath 30, along with the design of the inner sheath 30 being made of rubber and having a metal mesh, effectively prevents damage to the cable core 1 from the external environment, while also enhancing the tensile strength and abrasion resistance of the cable.

[0025] As a preferred embodiment, the tensile layer 32 is provided with a plurality of evenly distributed tensile strips, which are made of metal, and a tensile mesh is provided in the interlayer of the tensile layer 32. By providing a plurality of evenly distributed metal tensile strips and a tensile mesh in the tensile layer 32, the tensile strength of the cable is further enhanced, making the cable less prone to breakage or deformation when subjected to tensile force.

[0026] As a preferred embodiment, both the outer wall of the outer sheath 2 and the outer wall of the anti-slip protrusion 4 are provided with a wear-resistant coating, and ceramic particles are embedded in the anti-slip protrusion 4. By providing a wear-resistant coating on the outer walls of the outer sheath 2 and the anti-slip protrusion 4, and embedding ceramic particles in the anti-slip protrusion 4, the wear resistance and anti-slip effect of the cable are further improved, making the cable less prone to wear or slippage during long-term use.

[0027] As a preferred embodiment, the anti-slip protrusion 4 has embossed or laser-etched markings on the outer wall of the side away from the outer sheath 2. By embossing or laser-etching the outer wall of the anti-slip protrusion 4 away from the outer sheath 2, the roughness of the cable surface is increased, further improving the anti-slip performance of the cable, so that the cable can maintain good grip even in wet or slippery environments.

[0028] As a preferred embodiment, the outer sheath 2 is thicker than the bending strip 5. This ensures that the cable maintains good bending resistance while also guaranteeing its overall strength and abrasion resistance, thus extending its service life.

[0029] The wear-resistant and bending-resistant cable of this utility model includes, in use:

[0030] Wear-resistant and bending-resistant structural design: Through a specific structural design, including the cable core 1, outer sheath 2, and an intermediate layer 3 between them, the cable achieves improved wear resistance and bending resistance. Multiple evenly distributed anti-slip protrusions 4 on the outer surface of the outer sheath 2 not only increase the surface roughness of the cable and improve anti-slip performance, but also further enhance the cable's wear resistance through embedded ceramic particles and a wear-resistant coating. Simultaneously, several circular arrays of bending-resistant strips 5 within the outer sheath 2, composed of several tightly fitted thin metal strips 50, effectively improve the cable's bending resistance, making the cable less prone to damage when bent or subjected to external forces.

[0031] The multi-layer intermediate layer 3 design comprises, from the inside out, an inner sheath 30, a buffer layer 31, a tensile layer 32, a thermal insulation layer 33, and a reinforcing layer 34. This multi-layer structure further enhances the cable's abrasion resistance, tensile strength, thermal insulation, and overall strength. The inner sheath 30 is made of rubber and is fixedly connected to the outer ring wall of the cable core 1, effectively preventing damage to the cable core 1 from the external environment. Simultaneously, the metal mesh within the inner sheath 30 enhances the cable's tensile and abrasion resistance.

[0032] Tensile layer 32 design: Tensile layer 32 contains several evenly distributed metal tensile strips and tensile mesh. This design further enhances the tensile strength of the cable, making it less prone to breakage or deformation when subjected to tension, thus ensuring the stability and service life of the cable.

[0033] Synergistic effect of outer sheath 2 and anti-slip protrusions 4: Outer sheath 2 not only provides the outermost layer of protection for the cable, but also ensures the overall strength and wear resistance of the cable through its design, which is thicker than the anti-bending strip 5. At the same time, the synergistic effect of the wear-resistant coating and ceramic particles of outer sheath 2 and anti-slip protrusions 4 further enhances the wear resistance and anti-slip effect of the cable, making the cable less prone to wear or slippage during long-term use.

[0034] In summary, the wear-resistant and bending-resistant cable of this utility model, through its specific structural design, multi-layer intermediate layer 3 design, tensile layer 32 design, and the synergistic effect of outer sheath 2 and anti-slip protrusions 4, achieves a comprehensive improvement in the cable's wear resistance, bending resistance, tensile strength, thermal insulation, and anti-slip properties, enabling the cable to work stably under a wider range of environmental conditions and extending its service life.
