Description

Technical Field

[0001] This utility model relates to the field of outdoor cable technology, specifically to a tensile and abrasion-resistant outdoor cable. Background Technology

[0002] Outdoor cables are often affected by the external environment during use, and are also prone to friction with external objects during pulling, which can cause external damage to the cables.

[0003] Existing outdoor cables have the problem that the tensile force cannot be relieved, and the damaged cable shell is not easy to replace.

[0004] The reason for this problem is that when cables are used outdoors, they need to be installed on the outside of cable posts. During this process, the cables need to be bundled. Later, under external tension, the outer protective layer of the cable will rub against other structural components. Over time, this friction will damage the outer protective shell of the cable. Since the outer shell and the inner layer of the cable are tightly fixed, it is impossible to remove and reinstall a new outer layer of the cable at individual worn locations after damage, which affects the overall performance of the cable. Therefore, we propose a tensile and abrasion-resistant outdoor cable. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, this utility model proposes a tensile and wear-resistant outdoor cable, which solves the problem that the tensile force of the existing outdoor cable cannot be relieved and the worn cable shell of the cable damaged by the pull is not easy to replace.

[0006] To solve the above-mentioned technical problems, the basic technical solution proposed by this utility model is as follows: a tensile and abrasion-resistant outdoor cable, comprising a cable body, a protective layer provided on the outside of the cable body, an abrasion-resistant mechanism provided on the outside of the protective layer, the abrasion-resistant mechanism including an isolation layer disposed on the outside of the protective layer, the isolation layer being used to separate the cable body from the abrasion-resistant structure, a limiting ring disposed on the outside of the isolation layer, the limiting ring being used to relieve tensile force, a movable part movably sleeved on the outside of the limiting ring, the movable part reducing the frictional force generated by tension by moving outside the limiting ring, and a marking ring sleeved on the outside of the movable part, the marking ring being used to intermittently connect the outermost layer of the cable body.

[0007] Preferably, a connecting ring is provided on the outside of the isolation layer, and the limiting ring is sleeved on the outside of the connecting ring.

[0008] Preferably, a support ring is sleeved on the outside of the movable part, and the marking ring is disposed outside the support ring.

[0009] Preferably, a support ring is fixedly connected to the outside of the support ring at a position away from the marking ring, and a marking groove is formed on the outside of the marking ring.

[0010] Preferably, the outer side of the marking ring is fixedly connected with an anti-corrosion layer, and the inner side of the anti-corrosion layer abuts against the outer side of the support ring.

[0011] Preferably, the anti-corrosion layer is provided with a wear-resistant layer on the outside.

[0012] The beneficial effects of this utility model are:

[0013] The technical solution of this utility model involves setting a movable component outside the limiting ring. When the wear-resistant layer is subjected to tensile force, the wear-resistant layer will transfer the tensile force to the outside of the movable component, thereby causing the movable component at a certain position outside the isolation layer to slide outside the limiting ring. This reduces the squeezing and friction caused by the tensile force between the wear-resistant layer and other structures. If a portion of the wear-resistant layer needs to be cut off after being damaged by friction, it is only necessary to remove the anti-corrosion layer and wear-resistant layer above the marking groove above the area of ​​friction damage, and then scrape off the remaining anti-corrosion layer and wear-resistant layer outside the marking ring. By setting the movable component to be movably sleeved outside the limiting ring, the tensile and squeezing forces on the wear-resistant layer are alleviated, reducing tensile and friction damage. At the same time, the anti-corrosion layer outside the marking ring is quickly separated under the action of the marking groove, solving the problem of the difficulty in removing damaged protective shells.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] This application provides a tensile and abrasion-resistant outdoor cable, which solves the problem that the tensile force of existing outdoor cables cannot be relieved, and that it is not easy to replace the worn cable shell of the cable damaged by the pull.

[0022] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0023] According to the appendix Figure 1 - Figure 4 As shown, the cable includes a cable body 1, a protective layer 101 on the outside of the cable body 1, and a wear-resistant mechanism on the outside of the protective layer 101. The wear-resistant mechanism includes an isolation layer 2 on the outside of the protective layer 101. The isolation layer 2 is used to separate the cable body 1 from the wear-resistant structure. A limiting ring 201 is disposed on the outside of the isolation layer 2. The limiting ring 201 is used to relieve tensile force. A movable part 202 is movably sleeved on the outside of the limiting ring 201. The movable part 202 reduces the friction force generated by pulling by moving on the outside of the limiting ring 201. A marking ring 209 is sleeved on the outside of the movable part 202. The marking ring 209 is used to intermittently connect the outermost layer of the cable body 1.

[0024] A connecting ring 206 is provided on the outside of the isolation layer 2. A limiting ring 201 is sleeved on the outside of the connecting ring 206. A support ring 205 is sleeved on the outside of the movable part 202. A marking ring 209 is provided on the outside of the support ring 205. A support ring 204 is fixedly connected to the outside of the support ring 205 away from the marking ring 209. A marking groove 203 is opened on the outside of the marking ring 209. An anti-corrosion layer 207 is fixedly connected to the outside of the marking ring 209. The inner side of the anti-corrosion layer 207 abuts against the outside of the support ring 204. A wear-resistant layer 208 is provided on the outside of the anti-corrosion layer 207.

[0025] By providing a movable part 202 outside the limiting ring 201, both the movable part 202 and the limiting ring 201 are made of rubber, which can shrink under a certain degree of compressive force. When the wear-resistant layer 208 is subjected to tensile force, the wear-resistant layer 208 will transfer the tensile force to the outside of the movable part 202, thereby causing the movable part 202 at a certain position outside the isolation layer 2 to slide outside the limiting ring 201, thus reducing the compressive friction between the wear-resistant layer 208 and other structures caused by tensile force. If a portion of the wear-resistant layer 208 needs to be cut off after being damaged by friction, it is only necessary to cut off the anti-corrosion layer 207 and the wear-resistant layer 208 above the marking groove 203 above the damaged area. Then, scrape off the remaining anti-corrosion layer 207 and the wear-resistant layer 208 outside the marking ring 209. Finally, the new anti-corrosion layer 207 and the wear-resistant layer 208 are used externally. The glue can be reapplied to the outside of the marking ring 209, and finally the connection end can be wrapped and fixed with tape. This does not hinder the protection of the outermost layer of the cable body 1 by the anti-corrosion layer 207 and the wear-resistant layer 208, while reducing the connection area between the anti-corrosion layer 207 and the wear-resistant layer 208 and the inner layer. At the same time, the damaged anti-corrosion layer 207 and the wear-resistant layer 208 can be cut into sections according to the marking groove 203, so as to quickly deal with the outer anti-corrosion layer 207 and the wear-resistant layer 208 of the marking ring 209. By setting the movable part 202 to be movably sleeved on the outside of the limiting ring 201, the tensile and compressive forces on the wear-resistant layer 208 can be relieved, thereby reducing the damage caused by pulling and friction. At the same time, under the action of the marking groove 203, the outer anti-corrosion layer 207 of the marking ring 209 can be quickly separated, so that the damaged anti-corrosion layer 207 and the wear-resistant layer 208 can be removed and reinstalled, solving the problem that some protective shells are difficult to remove when damaged.

[0026] In summary, compared with existing technologies, it has the following beneficial effects:

[0027] By providing a movable member 202 outside the limiting ring 201, when the wear-resistant layer 208 is subjected to tensile force, the wear-resistant layer 208 will transmit the tensile force to the outside of the movable member 202, thereby causing the movable member 202 at a certain position outside the isolation layer 2 to slide outside the limiting ring 201. This reduces the squeezing and moving friction caused by the tensile force between the wear-resistant layer 208 and other structures. If a portion of the wear-resistant layer 208 needs to be removed after being damaged by friction, only the portion needs to be removed. The anti-corrosion layer 207 and wear-resistant layer 208 above the marking groove 203 above the friction damage area are removed. Then, the remaining anti-corrosion layer 207 and wear-resistant layer 208 on the outside of the marking ring 209 can be scraped off. By setting the movable part 202 to be movably sleeved on the outside of the limiting ring 201, the tensile and compressive forces on the wear-resistant layer 208 are relieved, reducing tensile and friction damage. At the same time, under the action of the marking groove 203, the anti-corrosion layer 207 on the outside of the marking ring 209 is quickly separated, solving the problem that some protective shells are difficult to remove when damaged.
