Description

Technical Field

[0001] This application relates to the field of polyurethane cable protection sleeve technology, and more particularly to a polyurethane cable protection sleeve. Background Technology

[0002] Cables, as a crucial component of modern power and communication systems, bear the critical responsibility of transmitting electrical energy and signals. However, during installation and use, cables often face multiple challenges, including mechanical damage, chemical corrosion, environmental factors, and electrical interference. These challenges not only affect cable performance and lifespan but can also potentially lead to safety hazards. To protect cables from these adverse factors, cable sheaths were developed and continue to evolve with advancements in materials science and manufacturing processes.

[0003] Currently, people mainly use rubber or plastic sheaths to wrap cables. Although these materials have a certain protective effect, they are difficult to adapt to the bending of cables and cannot play a good protective role when cables are bent. Therefore, an improvement has been made to a polyurethane sheath for cable protection. Utility Model Content

[0004] In view of the shortcomings of the prior art, this application provides a cable protection polyurethane sleeve, which overcomes the shortcomings of the prior art and aims to solve the problem that although the existing cable protection polyurethane sleeve has a certain protective effect, it is difficult to adapt to the bending of the cable and cannot play a good protective role when the cable is bent.

[0005] To achieve the above objectives, this application provides the following technical solution: a cable protection polyurethane sleeve, comprising a cable, wherein a plurality of cable protection polyurethane sleeves are sleeved on the outer wall of the cable, and the outer wall of each plurality of cable protection polyurethane sleeves is spirally formed with a spiral groove that communicates with the inner wall. One end of each cable protection polyurethane sleeve is provided with a socket, and the other end of each cable protection polyurethane sleeve is provided with a plug. The plug of any cable protection polyurethane sleeve can be slidably inserted into the socket of an adjacent cable protection polyurethane sleeve, and the plug is fixedly connected to the socket by a fixing adhesive.

[0006] By adopting the above technical solution, and by spirally opening spiral grooves on the outer wall of the cable protection polyurethane sheath, the bending flexibility of the cable protection polyurethane sheath can be enhanced while maintaining axial strength. This allows the cable protection polyurethane sheath to better conform to the bending radius of the cable, significantly reducing the stress on the cable during bending. Furthermore, this design enhances the deformation capacity of the cable protection polyurethane sheath under stress, enabling it to absorb and disperse external energy through deformation, thereby providing reliable protection for the cable and ensuring that it maintains excellent flexibility and adaptability during bending and twisting. Through the cooperation between the plug, fixing adhesive, and socket, multiple sections of cable protection polyurethane sheaths can be connected end to end.

[0007] As a preferred technical solution of this application, a threaded sleeve is embedded at the end of the cable protection polyurethane sleeve away from the socket, and a threaded connecting rod is inserted into the internal thread of the threaded sleeve, and the threaded connecting rod is fixedly connected to the plug.

[0008] By adopting the above technical solution, the threaded connecting rod is threaded into the threaded sleeve by rotating the plug, thereby achieving a fixed connection between the plug and the cable protection polyurethane sleeve. This design allows workers to replace plugs that are accidentally damaged during installation.

[0009] As a preferred technical solution of this application, the number of threaded sleeves, threaded connecting rods, plugs and sockets are all five times the number of cable protection polyurethane sleeves and correspond one-to-one, and the outer diameter of the plug is slightly smaller than the inner diameter of the socket.

[0010] By adopting the above technical solution, multiple connection nodes are set between two adjacent cable protection polyurethane sleeves to ensure splicing stability. The outer diameter of the plug should be slightly smaller than the inner diameter of the socket to ensure that the plug with the outer wall covered with fixing adhesive can be smoothly inserted into the socket.

[0011] As a preferred technical solution of this application, the outer wall of the plug is provided with an annular groove, and the interior of the annular groove is filled with fixing adhesive.

[0012] By adopting the above technical solution, the contact area between the plug and the fixing adhesive is increased, thereby improving the tightness of the connection.

[0013] As a preferred technical solution of this application, the length of the threaded connecting rod is adapted to the opening depth of the threaded sleeve, the side of the plug near the threaded sleeve is in contact with the outer wall of the threaded sleeve, and both the threaded sleeve and the threaded connecting rod are stainless steel components.

[0014] By adopting the above technical solution, the standardized installation of the plug can be completed when the threaded connecting rod is fully screwed into the threaded sleeve, ensuring that the plugs are of the same length and on the same plane after installation. The threaded sleeve and threaded connecting rod, made of stainless steel, are not easily corroded and have a long service life.

[0015] As a preferred technical solution of this application, the outer surface of the cable protection polyurethane sheath is coated with anti-oxidation paint.

[0016] By adopting the above technical solution, polyurethane material has good flexibility and weather resistance. By spraying anti-oxidation paint on the outer surface of the cable protection polyurethane sheath to form a dense protective layer, the outer wall of the cable protection polyurethane sheath is protected from oxidation and corrosion.

[0017] In summary, the beneficial effects of this application are as follows: 1. In this application, by spirally opening spiral grooves on the outer wall of the cable protection polyurethane sheath, the bending flexibility of the cable protection polyurethane sheath can be enhanced while maintaining axial strength. This allows the cable protection polyurethane sheath to better conform to the bending radius of the cable, significantly reducing the stress on the cable during bending. Furthermore, this design enhances the deformation capacity of the cable protection polyurethane sheath under stress, enabling it to absorb and disperse external energy through deformation, thereby providing reliable protection for the cable and ensuring that it maintains excellent flexibility and adaptability during bending and twisting. Through the cooperation between the plug, fixing adhesive, and socket, multiple sections of cable protection polyurethane sheath can be connected end to end.

[0018] 2. In this application, the threaded connecting rod is threaded into the threaded sleeve by rotating the plug, thereby achieving a fixed connection between the plug and the cable protection polyurethane sleeve. This design allows workers to replace plugs that are accidentally damaged during installation. Attached Figure Description

[0021] To make the technical means, creative features, objectives and effects of this application easy to understand, the following describes this application in conjunction with specific implementation methods.

[0022] like Figure 1 - Figure 4As shown in the figure, this embodiment provides a cable protection polyurethane sleeve, including a cable 1. A plurality of cable protection polyurethane sleeves 2 are sleeved on the outer wall of the cable 1. Each cable protection polyurethane sleeve 2 has a spiral groove 3 spirally formed on its outer wall, communicating with its inner wall. One end of each cable protection polyurethane sleeve 2 has a socket 4, and the other end has a plug 5. The plug 5 of any cable protection polyurethane sleeve 2 can be slidably inserted into the socket 4 of an adjacent cable protection polyurethane sleeve 2. The plug 5 is fixedly connected to the socket 4 by a fixing adhesive 6. In use, the spiral groove 3 on the outer wall of the cable protection polyurethane sleeve 2... The spiral groove 3 enhances the bending flexibility of the cable protection polyurethane sleeve 2 while maintaining axial strength, allowing the cable protection polyurethane sleeve 2 to better conform to the bending radius of the cable 1, significantly reducing the stress on the cable 1 during bending. This design also enhances the deformation capacity of the cable protection polyurethane sleeve 2 under stress, enabling it to absorb and disperse external energy through deformation, thereby providing reliable protection for the cable 1 and ensuring that it maintains excellent flexibility and adaptability during bending and twisting. Through the cooperation between the plug 5, the fixing adhesive 6, and the socket 4, multiple sections of the cable protection polyurethane sleeve 2 can be connected end to end.

[0023] In this embodiment, as Figure 3 and 4 As shown, a threaded sleeve 7 is embedded at the end of the cable protection polyurethane sleeve 2 away from the socket 4. A threaded connecting rod 8 is inserted into the threaded sleeve 7. The threaded connecting rod 8 is fixedly connected to the plug 5. In use, the threaded connecting rod 8 is screwed into the threaded sleeve 7 by rotating the plug 5, thereby achieving a fixed connection between the plug 5 and the cable protection polyurethane sleeve 2. This design allows the staff to replace the plug 5 that is damaged due to accident when it is ready for installation.

[0024] In this embodiment, as Figure 3 and 4 As shown, the number of threaded sleeves 7, threaded connecting rods 8, plugs 5, and sockets 4 are all five times the number of cable protection polyurethane sleeves 2 and correspond one-to-one. The outer diameter of plug 5 is slightly smaller than the inner diameter of socket 4. In use, multiple connection nodes are set between two adjacent cable protection polyurethane sleeves 2 to ensure the splicing stability. The outer diameter of plug 5 is slightly smaller than the inner diameter of socket 4 to ensure that plug 5, whose outer wall is covered with fixing adhesive 6, can be smoothly inserted into socket 4.

[0025] In this embodiment, as Figure 3 and 4 As shown, an annular groove 9 is formed around the outer wall of the plug 5, and the interior of the annular groove 9 is filled with fixing adhesive 6. During use, the contact area between the plug 5 and the fixing adhesive 6 is increased, thereby improving the tightness of the connection.

[0026] In this embodiment, as Figure 3 and 4 As shown, the length of the threaded connecting rod 8 is matched with the opening depth of the threaded sleeve 7. The side of the plug 5 closest to the threaded sleeve 7 is in contact with the outer wall of the threaded sleeve 7. Both the threaded sleeve 7 and the threaded connecting rod 8 are stainless steel components. In use, the standardized installation of the plug 5 can be completed when the threaded connecting rod 8 is fully screwed into the threaded sleeve 7, ensuring that the plug 5 is of the same length and on the same plane after installation. The threaded sleeve 7 and the threaded connecting rod 8, made of stainless steel, are not easily corroded and have a long service life.

[0027] In this embodiment, as Figure 1 As shown, the outer surface of the cable protection polyurethane sleeve 2 is coated with anti-oxidation paint. During use, the polyurethane material has good flexibility and weather resistance. By spraying anti-oxidation paint on the outer surface of the cable protection polyurethane sleeve 2 to form a dense protective layer, the outer wall of the cable protection polyurethane sleeve 2 is prevented from being oxidized and corroded, thus protecting the cable protection polyurethane sleeve 2.

[0028] The working principle of this application is as follows: When using a cable protection polyurethane sleeve of this application, the cable protection polyurethane sleeve 2 is first wrapped and installed on the outer wall of the cable 1. Then, the threaded connecting rod 8 is threaded into the threaded sleeve 7 by rotating the plug 5, thus fixing the plug 5 and the cable protection polyurethane sleeve 2 together. After that, the fixing adhesive 6 is applied to the outer wall of the plug 5 and inserted into the adjacent socket 4, thus connecting multiple sections of cable protection polyurethane sleeve 2 end to end. Since the outer wall of the cable protection polyurethane sleeve 2 has a spiral groove 3, the cable protection polyurethane sleeve 2 can better fit the bending radius of the cable 1 during use. When the cable protection polyurethane sleeve 2 is under stress, it can absorb and disperse external energy through deformation, providing reliable protection for the cable 1 and ensuring that it always maintains excellent flexibility and adaptability during bending and twisting.
