Description

Technical Field

[0001] This utility model relates to the field of cable protection sleeves, specifically a glass fiber braided cable protection sleeve. Background Technology

[0002] Cable conduits are a common type of conduit used in electrical installations to protect electrical wires. They are suitable for telecommunications, power engineering, transportation, urban construction, and other fields. Cable protection conduits are mainly installed at the intersection of power lines and communication lines to protect the cables and prevent them from being affected by the surrounding environment, such as corrosion or uneven foundation settlement, which could cause the cables to break and affect production activities.

[0003] To further enhance cable protection, existing cable protection sleeves typically include support rings or brackets inside, allowing the cable to be suspended within the sleeve. However, during actual installation, to ensure the cable remains suspended, the cable ends are tightened. Since the cable is inserted into the sleeve from one end, the small inner diameter of the support ring or bracket makes installation difficult, and also hinders the disassembly of the cable should it fail.

[0004] In summary, the above structure is inconvenient to install in actual use because the inner diameter of the support ring or bracket is small, and it is also inconvenient for workers to disassemble it when the cable fails or is damaged. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide a glass fiber braided cable protection sleeve to solve the technical problem that the inner diameter of the support ring or bracket is small, which makes it inconvenient to install and also inconvenient for workers to disassemble the cable when it fails or is damaged.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a glass fiber braided cable protection sleeve, comprising a tube body, wherein a front end and a rear end are respectively provided at both ends of the tube body, an insertion rod is elastically provided on the front end, and an insertion hole for inserting the insertion rod is provided on the rear end, and a guide post that cooperates with the insertion rod is elastically provided on both the front end and the rear end, and a pad is connected to the other end of the guide post through the front end and the rear end respectively.

[0007] By adopting the above technical solution, during the splicing of the pipes, the insertion rod on the front end will be inserted into the insertion hole of the rear end. At this time, the insertion rod will squeeze the guide post in the rear end, so that the pad on the rear end first provides limiting support for one end of the cable. Then, when the splicing is limited through the mounting hole, the insertion rod itself will move to the rear end, thereby allowing the pad on the front end to provide limiting support for the other end of the cable. This process facilitates the subsequent quick installation and removal of the cable in the pipe, while ensuring that the cable is suspended in the pipe.

[0008] The present invention is further configured such that the outermost layer of the tube body is provided with a wear-resistant layer, and the innermost layer of the tube body is provided with a waterproof layer, and an insulating layer is provided between the wear-resistant layer and the waterproof layer, and the insulating layer itself is woven into the middle layer of the tube body.

[0009] Preferably, the wear-resistant layer is made of polyurethane, which has good wear resistance and aging resistance. The waterproof layer is made of polyvinyl chloride, which can effectively prevent water molecules in the air from entering the tube and effectively prevent the cable from failing during use. The insulation layer is made of glass fiber, which is woven into the middle layer of the sleeve. It has good insulation and heat resistance, as well as good corrosion resistance, which improves the service life of the tube.

[0010] The present invention is further configured such that an array of reinforcing ribs are evenly arranged on the outer wall of the tube between the front end and the rear end.

[0011] Preferably, the addition of reinforcing ribs effectively improves the stability of the front and rear ends of the tube, thereby increasing the mechanical strength of the tube and enhancing its overall compressive strength.

[0012] The present invention is further configured such that both the front end head and the rear end head are provided with mounting holes for the bolt assembly to pass through.

[0013] Preferably, the mounting holes facilitate workers to connect the front end to the rear end on another set of pipes using bolt assemblies, ensuring the stability of the connection.

[0014] The present invention is further provided that the inner side of the pad is provided with a protective sleeve, and the protective sleeve itself is located inside the pad and is detachable.

[0015] Preferably, the protective sleeve prevents direct contact between the cable and the inner wall of the pad, further reducing wear on the outer wall of the cable during movement and ensuring the cable's service life.

[0016] The present invention is further configured such that the connection points between both ends of the insertion rod and the guide post are arc-shaped, and a smooth surface is provided on the arc-shaped end face.

[0017] Preferably, the arc-shaped end face prevents the guide post from getting stuck during the sliding of the insertion rod, and the smooth surface of the outer wall effectively reduces the sliding friction between the insertion rod and the guide post, improving the stability of the insertion rod driving the guide post.

[0018] The present invention is further configured such that the force exerted by the elastic component at the insertion rod is greater than the force exerted by the elastic component at the guide post.

[0019] Preferably, when the insertion rod contacts one end of the guide post, its elastic force is greater than that of the guide post, so the insertion rod will squeeze the guide post at one end, thereby causing the guide post to slide along the pad. When the insertion rod moves to the inner end of the insertion hole, it is limited. At this time, when the two sets of tubes are spliced ​​through the mounting hole, the insertion rod itself will slide to one side of the front end head, thereby squeezing the guide post inside the front end head.

[0020] The present invention is further configured such that one end of the socket is open.

[0021] Preferably, the open design guides the insertion rod, ensuring that it can slide stably into the insertion hole, thus completing the splicing of the front and rear ends.

[0022] In summary, the present invention has the following main advantages:

[0023] 1. This utility model features a wear-resistant layer on the outer wall of the pipe body, made of polyurethane material, which has good wear resistance and aging resistance. At the same time, a waterproof layer made of polyvinyl chloride is set at the innermost layer of the pipe body, which can effectively prevent water molecules in the air from entering the pipe body and effectively prevent the cable from failing during use. Furthermore, an insulating layer made of glass fiber is set between the waterproof layer and the wear-resistant layer. The insulating layer is woven into the middle layer of the sleeve and has good insulation and heat resistance, as well as good corrosion resistance, thus improving the service life of the pipe body.

[0024] 2. This utility model has a front end and a rear end set at both ends of the tube body, and a pad is set in both the front end and the rear end. During the splicing of the tube bodies, the plug on the front end will be inserted into the plug hole of the rear end. At this time, the plug will press the guide post in the rear end, so that the pad on the rear end first provides limiting support for one end of the cable. Then, when the two ends are spliced ​​and limited through the mounting hole, the plug itself will move to the rear end, so that the pad on the front end provides limiting support for the other end of the cable. This process facilitates the workers to quickly disassemble and assemble the cable in the tube body, while ensuring that the cable is suspended in the tube body. Attached Figure Description

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0034] The embodiments of this utility model will be described below based on its overall structure.

[0035] First embodiment:

[0036] Please see Figures 1-5The fiberglass braided cable protection sleeve shown includes a tube body 1, a front end 3, a rear end 4, an elastic component, a support mechanism, and a limiting mechanism. A set of reinforcing ribs 2 are evenly arranged on the outer wall of the tube body 1 between the front end 3 and the rear end 4. The arrangement of the reinforcing ribs 2 effectively improves the stability of the front end 3 and the rear end 4 at both ends of the tube body 1, thereby increasing the mechanical strength of the tube body 1 and improving the overall compressive strength of the tube body 1. At the same time, the pads 7 inside the front end 3 and the rear end 4 are in the open state under normal conditions, which makes it convenient for workers to directly pass the cable through the tube body and quickly install the cable. Since a plug rod 9 is elastically provided on the front end 3 and a plug hole 6 for the plug rod 9 is opened on the rear end 4, the worker inserts the plug rod 9 into the plug hole 6 of the rear end 4 on the other set of tube body 1.

[0037] Since both the front end 3 and the rear end 4 are elastically equipped with guide posts 8 that cooperate with the insertion rod 9, and the other end of the guide post 8 passes through the front end 3 and the rear end 4 respectively and is connected to a pad 7, the insertion rod 9 will squeeze the guide post 8 on the rear end 4, so that the pad 7 will limit and support one end of the cable. When the insertion rod 9 is inserted into the bottom end of the insertion hole 6, there is still a certain gap between the front end 3 and the rear end 4. At this time, with the action of the mounting hole 5, it is convenient for the staff to tightly splice the front end 3 and the rear end 4 on the other set of tubes 1 with bolts. Since the insertion rod 9 itself is elastically set on the front end 3, the insertion rod 9 will slide to one side of the front end 3, so that the pad 7 on the front end 3 will limit and support the other end of the cable. During this process, it is convenient for the staff to quickly disassemble and assemble the cable in the tube 1, while ensuring that the cable is suspended in the tube 1.

[0038] For details regarding the above embodiments, please refer to [link / reference]. Figure 1 The inner side of the pad 7 is provided with a protective sleeve, and the protective sleeve itself is located inside the pad 7 and is detachable. The protective sleeve prevents the cable from directly contacting the inner wall of the pad 7, further reducing the wear on the outer wall of the cable during movement and ensuring the service life of the cable itself.

[0039] For details regarding the above embodiments, please refer to [link / reference]. Figure 3 and Figure 4The elastic component at the insertion rod 9 exerts a greater force than the elastic component at the guide post 8. When the insertion rod 9 contacts one end of the guide post 8, its elastic force is greater than that at the guide post 8. Therefore, the insertion rod 9 will squeeze the guide post 8 at one end, causing the guide post 8 to slide along the pad 7. When the insertion rod 9 moves to the inner end of the insertion hole 6, it is limited. At this time, when the two sets of tubes 1 are spliced ​​through the mounting hole 5, the insertion rod 9 will slide to one side of the front end head 3, thereby squeezing the guide post 8 inside the front end head 3.

[0040] Second embodiment:

[0041] Please see Figure 6 The fiberglass braided cable protection sleeve shown has an overall structure similar to that of Embodiment 1. The outermost layer of the tube body 1 is provided with a wear-resistant layer 101, which is made of polyurethane material and has good wear resistance and aging resistance. The innermost layer of the tube body 1 is provided with a waterproof layer 103, which is made of polyvinyl chloride material and can effectively prevent water molecules in the air from entering the tube body 1, thus effectively preventing the cable from failing during use. An insulation layer 102 is provided between the wear-resistant layer 101 and the waterproof layer 103. The insulation layer 102 is braided into the middle layer of the tube body and is made of fiberglass. It has good insulation and heat resistance, as well as good corrosion resistance, which improves the service life of the tube body 1.

[0042] In practical operation, this invention works as follows: First, the cable is passed through multiple sets of pipe bodies 1. Then, the front end 3 of pipe body 1 is spliced ​​with the rear end 4 of another set of pipe bodies 1. At this time, the insertion rod 9 on the front end 3 is inserted into the insertion hole 6 of the rear end 4 on the other set of pipe bodies 1. The insertion rod 9 then presses against the guide post 8 on the rear end 4, thereby causing the guide post 8 on the rear end 4 to drive the pad 7 to support one end of the cable. During this process, there is still a gap between the front end 3 and the rear end 4. At this time, the front end 3 and the rear end 4 are tightly spliced ​​through the mounting hole 5. Since the insertion rod 9 itself is elastically set on the front end 3, it will slide to one side of the front end 3 during the splicing process, thereby pressing against the guide post 8 inside the front end 3. During this process, the pad 7 on the front end 3 supports the other end of the cable. This process facilitates the subsequent quick installation and removal of the cable inside the pipe body 1 by the operator, while ensuring that the cable is suspended inside the pipe body.
