Description

Technical Field

[0001] This utility model relates to the field of cable protection technology, specifically to a cable with a fiber composite reinforcement layer. Background Technology

[0002] Cables are transmission media composed of multiple metal conductors, insulation materials, and sheath layers. They are mainly used for power transmission, signal transmission, or data communication and are widely used in construction, industry, communications, and other fields. Their structure ensures stable transmission of current or information through multi-layer protection, while also possessing anti-interference and environmental resistance characteristics.

[0003] Chinese patent discloses a cable sheath for reducing frictional damage (publication number: CN220252868U). This device enhances the overall corrosion resistance, aging resistance, and wear resistance of the cable by incorporating fiber-reinforced composite material, carboxylated nitrile rubber layer, and wear-resistant rubber layer within the wear-resistant outer sheath. This reduces damage caused by tensile friction during cable use and improves the cable's durability. However, this device still has the following problems:

[0004] Although the above-mentioned device is equipped with a reinforced sheath layer such as fiber-reinforced composite material, the sheath layer is still prone to damage when the cable is dragged or laid over a long distance due to prolonged direct friction with the ground surface. Therefore, a cable with a fiber composite reinforcement layer is proposed to solve the above problems. Utility Model Content

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A cable with a fiber composite reinforcement layer includes a cable body, and a support mechanism is provided on the outside of the cable body;

[0007] The support mechanism includes a first clamping plate, and a second clamping plate is provided on one side of the first clamping plate. Both the first and second clamping plates are arc-shaped, and the outer diameters of adjacent first and second clamping plates are the same. A first ball bearing is embedded in and movably connected to the surface of the first clamping plate. At least three first balls bearings are provided inside the first clamping plate, and each first ball bearing is equidistantly arranged along the surface of the first clamping plate. A second ball bearing is embedded in and movably connected to the surface of the second clamping plate. At least three second balls bearings are provided inside the second clamping plate, and each second ball bearing is equidistantly arranged along the surface of the second clamping plate.

[0008] As a further embodiment of this utility model: the upper and lower ends of the outer walls of the first clamping plate are fixedly connected to the insertion shafts, and the upper and lower ends of the outer walls of the second clamping plate are provided with insertion holes.

The surface of the magnet is magnetically connected to the end of the insertion shaft.

[0009] As a further embodiment of this utility model: the top and bottom surfaces of the first clamping plate and the second clamping plate are both fixedly connected with extension plates, and the ends of each extension plate are also fixedly installed with insert plates.

[0010] As a further embodiment of this utility model: each of the extension plates and insert plates is arc-shaped, and the outer wall of the extension plate is also fixedly connected with a number of convex shafts, each of the convex shafts being arranged equidistantly around the surface of the extension plate.

[0011] As a further embodiment of this utility model: the maximum outer diameter of the extension plate and the insert plate is smaller than the outer diameter of the second clamping plate and the first clamping plate, the outer diameter of the insert plate gradually decreases in the direction away from the second clamping plate, and the inner diameters of the extension plate, the insert plate, the second clamping plate and the first clamping plate are all the same.

[0012] As a further embodiment of this utility model: heat shrink tubing is provided on the outer side of the extension plate and the insert plate, and the inner side of the heat shrink tubing abuts against the surface of each convex shaft.

[0013] As a further embodiment of this utility model: the cable body includes a sheath layer, a fiber composite reinforcement layer is embedded and fixed inside the sheath layer, an insulation layer is embedded and fixed inside the fiber composite reinforcement layer, a conductor is embedded and fixed inside the insulation layer, the outer side of the sheath layer abuts against the first clamping plate and the second clamping plate, and the outer side of the sheath layer is also sleeved and abuts against the inner side of the heat shrink tubing.

[0014] The beneficial effects of this utility model are:

[0015] (1) The present invention provides a first clamping plate and a second clamping plate structure with ball bearings on the outermost layer of the cable. When the cable is dragged in the cable tray or pipe, the friction between the cable and the contact surface can be significantly reduced due to the support of the ball bearings, thereby reducing the wear of the outer sheath and extending the service life of the cable. This structure has a better effect in scenarios where the cable needs to be moved frequently, such as construction or equipment maintenance.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1-4As shown, a cable with a fiber composite reinforcement layer includes a cable body 1, and a support mechanism 2 is provided on the outside of the cable body 1. The support mechanism 2 includes a first clamping plate 201, and a second clamping plate 203 is provided on one side of the first clamping plate 201. Both the first clamping plate 201 and the second clamping plate 203 are arc-shaped, and the outer diameters of adjacent first clamping plates 201 and second clamping plates 203 are the same. First balls 202 are embedded in and movably connected to the surface of the first clamping plate 201. At least three first balls 202 are provided inside the first clamping plate 201, and each first ball 202 is equidistantly arranged along the surface of the first clamping plate 201. Second balls 204 are embedded in and movably connected to the surface of the second clamping plate 203. At least three second balls 204 are provided inside the second clamping plate 203, and each second ball 204 is equidistantly arranged along the surface of the second clamping plate 203. Figure 2 As shown, the first clamping plate 201 and the second clamping plate 203 can both be made of polyoxymethylene, while the first ball 202 and the second ball 204 are both made of stainless steel or high carbon chromium bearing steel.

[0025] The upper and lower ends of both sides of the outer wall of the first clamping plate 201 are fixedly connected with insertion shafts 211. The upper and lower ends of both sides of the outer wall of the second clamping plate 203 are provided with insertion holes 205. Each insertion hole 205 is inserted into a different insertion shaft 211. A magnet 206 is also glued and fixed to the inner end of each insertion hole 205. The surface of the magnet 206 is magnetically connected to the end of the insertion shaft 211. Figures 2-3 The insert shaft 211 shown is made of iron and can be attracted and positioned by magnet 206.

[0026] Extension plates 207 are fixedly connected to the top and bottom surfaces of both the first clamping plate 201 and the second clamping plate 203. Insert plates 209 are also fixedly installed at the ends of each extension plate 207. Both the extension plates 207 and the insert plates 209 are arc-shaped. Several convex shafts 208 are fixedly connected to the outer wall of each extension plate 207, and these convex shafts 208 are equidistantly arranged around the surface of the extension plate 207. Figure 1 As shown, when the heat shrink tubing 210 is tightened, the contact area between the convex shaft 208 and the heat shrink tubing is increased, thus making it less likely for the heat shrink tubing 210 to fall off.

[0027] The maximum outer diameters of the extension plate 207 and the insert plate 209 are both smaller than the outer diameters of the second clamping plate 203 and the first clamping plate 201. The outer diameter of the insert plate 209 gradually decreases in the direction away from the second clamping plate 203. The inner diameters of the extension plate 207, the insert plate 209, the second clamping plate 203, and the first clamping plate 201 are all the same. Figure 2 As shown, the insert plate 209 has a sloping surface on the outside to facilitate insertion into the heat shrink tubing 210.

[0028] Heat shrink tubing 210 is fitted onto the outer sides of the adjacent extension plate 207 and insert plate 209. The inner side of the heat shrink tubing 210 abuts against the surface of each convex shaft 208, such as... Figure 2 As shown, the heat shrink tubing 210 can be made of polyolefin material.

[0029] The cable body 1 includes a sheath layer 101, a fiber composite reinforcement layer 102 is embedded and fixed inside the sheath layer 101, an insulation layer 103 is embedded and fixed inside the fiber composite reinforcement layer 102, a conductor 104 is embedded and fixed inside the insulation layer 103, the outer side of the sheath layer 101 abuts against the first clamping plate 201 and the second clamping plate 203, and the outer side of the sheath layer 101 is also sleeved and abuts against the inner side of the heat shrink tubing 210.

[0030] The working principle of this utility model:

[0031] Before laying the cable, multiple heat shrink tubes 210 can be fitted over the outside of the cable, and a first clamping plate 201 and a second clamping plate 203 can be installed between adjacent heat shrink tubes 210. After the insert shaft 211 is inserted into the socket 205, the magnet 206 attracts and positions the end of the insert shaft 211, thereby preventing the insert shaft 211 from easily coming out of the socket 205. Then, one side of the heat shrink tube 210 is fitted over the outside of the inserting plate 209 and the convex shaft 208, while the other side of the heat shrink tube 210 remains fitted over the outside of the sheath layer 101. Then, the heat shrink tube 210 is heated, and after the heat shrink tube 210 shrinks, it tightens the first clamping plate 201 and the second clamping plate 203, further preventing the first clamping plate 201 and the second clamping plate 203 from separating, and at the same time preventing the support mechanism 2 from sliding on the outside of the cable body 1.

[0032] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
