Description

Technical Field

[0001] The utility model relates to the technical field of cable sheaths, in particular to a novel wear-resistant cable sheath. Background Art

[0002] Wires and cables are wire products that transmit electrical energy, electrical signals and realize electromagnetic energy conversion. They are mainly composed of two parts: a cable core that transmits electricity or electrical signals and a sheath that plays a protective and insulating role.

[0003] The cables in the existing general technology usually include a cable core and a sheath layer arranged on the outside of the cable core. Users usually put the finished cables into use directly after purchasing them. For some scenarios where cables are often subjected to friction, such as municipal equipment power supply cables, the operating scenes of the equipment are usually concrete pavements, etc. There is a lot of friction between the cable and the ground when the cable is dragged to adjust the operating position. After a long time, it is easy to cause greater friction damage to the cable sheath, and even cause safety accidents. Therefore, it is necessary to improve the relevant technologies. Utility Model Content

[0004] In order to solve the above problems, the utility model provides a novel wear-resistant cable sheath.

[0005] The above technical purpose of the utility model is achieved through the following technical solutions: a new type of cable wear-resistant sheath, including a wear-resistant sheath for use with a cable body, the inner surface of the wear-resistant sheath is in contact with the outer surface of the cable body, and the wear-resistant sheath is provided with a slit connected to the inner wall of the wear-resistant sheath, the two ends of the slit are respectively connected to the two ends of the wear-resistant sheath, and the extension direction of the slit is consistent with the extension direction of the wear-resistant sheath.

[0006] By adopting the above technical solution and setting the fine slit, it is convenient for the user to push aside the wear-resistant sheath and put the wear-resistant sheath on the cable body. After the wear-resistant sheath wraps the cable body, it plays a good protective role on the cable body, and fully reduces the probability of damaging the cable body or even causing a safety accident due to direct friction between the cable body and the ground.

[0007] Furthermore, the wear-resistant sheath is provided with spindle parts near both ends thereof, the outer diameter of the spindle parts decreases from the middle of the spindle parts to both sides, a rubber binding ring is provided on the spindle part, and an annular groove matching the rubber binding ring is provided on the outer wall of the spindle part, and the position of the inner surface of the wear-resistant sheath corresponding to the rubber binding ring is tightly pressed against the outer surface of the cable body.

[0008] By adopting the above technical scheme, the rubber binding ring is made of rubber material and has good elastic force and binding effect. After the rubber binding ring is installed in the annular groove from the end with a smaller diameter of the spindle part, the inner surface of the wear-resistant sheath at the corresponding position of the rubber binding ring is pressed against the outer surface of the cable body, thereby enhancing the stability of the connection between the wear-resistant sheath and the cable body, reducing the probability of the wear-resistant sheath displacing axially along the cable body, which is beneficial for the wear-resistant sheath to fully protect the cable body.

[0009] Furthermore, an annular rubber sheet is provided at a position on the inner surface of the wear-resistant sheath corresponding to the annular groove, an opening is provided at a position on the annular rubber sheet corresponding to the slit, and a position on the inner surface of the annular rubber sheet corresponding to the rubber binding ring is pressed against the outer surface of the cable body.

[0010] By adopting the above technical solution, the annular rubber sheet is made of rubber material, and its surface has a large friction coefficient. Under the action of the rubber binding ring, the inner surface of the annular rubber sheet is pressed against the outer surface of the cable body, thereby increasing the friction between the inner surface of the wear-resistant sheath and the outer surface of the cable body, and reducing the probability of displacement of the wear-resistant sheath during use.

[0011] Furthermore, a plurality of rubber protrusions are evenly fixed on the inner surface of the annular rubber sheet, and the surfaces of the plurality of rubber protrusions are tightly pressed against the outer surface of the cable body.

[0012] By adopting the above technical solution, the rubber protrusion is also made of rubber material, and its surface has a large friction coefficient. Under the action of the rubber binding ring, the surface of the rubber protrusion is tightly pressed against the outer surface of the cable body, which further enhances the stability of the wear-resistant sheath during use and is conducive to the wear-resistant sheath to fully exert its good protective effect.

[0013] Furthermore, the wear-resistant sheath is provided with a tying wire for binding the wear-resistant sheath.

[0014] By adopting the above technical solution, after the binding wire is tightened, the wear-resistant sheaths on both sides of the slit are bound together, which is conducive to maintaining good connection stability between the wear-resistant sheath and the cable body.

[0015] Furthermore, a scraping assembly is provided at one end of the wear-resistant sheath, and the scraping assembly includes a diamond block and an L-shaped rod body fixed to one side of the diamond block.

[0016] By adopting the above technical solution, when the narrow gap is opened and the wear-resistant sheath is put on the cable body, the staff can pull the diamond block through the L-shaped rod, and the narrow gap can be easily opened through the diamond block, thereby reducing the difficulty for the staff to open the narrow gap and put the wear-resistant sheath on the cable body.

[0017] Furthermore, an anti-fall-off column is fixed to one end of the L-shaped rod body away from the diamond-shaped block.

[0018] By adopting the above technical solution and the setting of the anti-slip column, the probability of the staff slipping when holding the L-shaped rod and using the diamond block to open the narrow gap is reduced.

[0019] In summary, the utility model has the following beneficial effects:

[0020] 1. In the present application, the setting of the slit makes it easy for the user to pull open the wear-resistant sheath and put the wear-resistant sheath on the cable body. After the wear-resistant sheath wraps the cable body, it plays a good protective role on the cable body, and fully reduces the probability of damaging the cable body or even causing safety accidents due to direct friction between the cable body and the ground;

[0021] 2. In the present application, the rubber binding ring is made of rubber material and has good elastic force and binding effect. After the rubber binding ring is installed in the annular groove from the end with a smaller diameter of the spindle part, the inner surface of the wear-resistant sheath at the corresponding position of the rubber binding ring is pressed against the outer surface of the cable body, thereby enhancing the stability of the connection between the wear-resistant sheath and the cable body, reducing the probability of the wear-resistant sheath displacing along the axial direction of the cable body, and facilitating the wear-resistant sheath to fully protect the cable body.

The setting of the slit 11 makes it convenient for the user to open the wear-resistant sheath 1 and put the wear-resistant sheath 1 on the cable body 8. After the wear-resistant sheath 1 wraps the cable body 8, it plays a good protective role on the cable body 8, and fully reduces the probability of damaging the cable body 8 or even causing a safety accident due to direct friction between the cable body 8 and the ground.

[0030] In order to enhance the connection stability between the wear-resistant sheath 1 and the cable body 8, the wear-resistant sheath 1 is provided with a tie wire 2 for binding the wear-resistant sheath 1, and at least two tie wires 2 are provided.
