[0021] like Figures 1 to 4As shown, the utility model relates to a single-core composite cable clamp, which includes an upper fixing part 1 and a lower fixing part 2. The upper fixing part 1 and the lower fixing part 2 are connected to form a circular fixing cavity. The inner wall of the fixing cavity is coated with an inner lining layer 4 and a composite material layer 5 respectively. Threaded holes are opened on both sides of the upper fixing part 1 and the lower fixing part 2, and screws 9 are connected to the threaded holes at both ends.

[0022] A protective sleeve 10 is fixedly connected to both sides of the upper fixing part 1 and the lower fixing part 2. The inner wall of the protective sleeve 10 is bonded to the surface of the cable through a rubber sleeve. The material of the inner lining layer 4 is set to rubber material. The composite material layer 5 is arranged on the outside of the inner lining layer 4. The surface of the composite material layer 5 is bonded to the surface of the cable. The composite material layer 5 can be selected from glass fiber reinforced unsaturated or resin-based composite materials. By setting the inner lining layer 4 and the composite material layer 5, the two are combined to form a single-core composite cable clamp, which has the advantages of good corrosion resistance, simple installation, and long service life. The composite material layer 5 can effectively prevent corrosion between the clamp and the cable, improve the safe operation capability of the cable, and be suitable for cable fixing in various environments, thereby improving the practicality of the device.

[0023] like Figure 1 、 Figure 2 and Figure 4 As shown, in the embodiment of the present utility model, the surface of the protective sleeve 10 is fixedly connected to the limiting sleeve 3, the limiting sleeve 3 is symmetrically distributed in an open shape, the limiting sleeve 3 includes an elastic sleeve 31 with an equidistant ring shape, and the two adjacent sides of the elastic sleeve 31 are arranged with a fixing portion 32. The two sides of one limiting sleeve 3 are fixedly connected to an elastic rope 6, and the two sides of the other limiting sleeve 3 are fixedly connected to a connecting buckle 7. The elastic rope 6 is passed through the sleeve hole and is arranged on the surface of the connecting buckle 7. The limiting sleeve 3 is fixed with a pressure plate 8 relative to the limiting sleeve 3. The limiting sleeve 3 and the protective sleeve 10 are both set to elastic materials. For example, rubber deformable protective material, by setting a protective sleeve 10 and a limiting sleeve 3, the elastic force of the pressure plate 8 can be used to press the position of the protective sleeve 10, so that the protective sleeve 10 fits with the surface of the cable, thereby protecting the connection between the cable and the clamp, and when the cable is bent, the limiting sleeve 3 and the pressure plate 8 can be squeezed so that the limiting sleeve 3 can fit the surface of the cable and bend, increasing the protection points at the bending point of the cable, avoiding friction and wear at the connection between the surface of the cable and the clamp, improving the protection of the cable, and ensuring the operation of the cable.

[0024] Working principle: This embodiment provides a single-core composite cable clamp. When in use, the cable is first placed on the upper surface of the lower fixing part 2, and the surface of the protective sleeve 10 is pressed by the pressure plate 8 to fit the surface of the cable, and then the upper fixing part 1 is clamped to the upper surface of the cable, and the protective sleeve 10 of the upper fixing part 1 is fit to and protected by the surface of the cable, and then the screws 9 are simultaneously rotated to both sides of the upper fixing part 1 and the lower fixing part 2, so that the upper fixing part 1 and the lower fixing part 2 are tightly fixed to the cable at the same time, and an inner lining layer 4 is made of a rubber pad matching the outer diameter of the cable, and a composite material layer 5 such as glass fiber reinforced unsaturated or resin-based composite material is coated on the surface of the inner lining layer 4, and a combined connection is made between the inner lining layer 4 and the composite material layer 5 to form a single-core composite cable clamp. After fixing the cable surface, the protective sleeve 10 is used to protect the connection between the cable and the upper fixing part 1 and the lower fixing part 2 and apply a certain pressure to the cable in its relative position to prevent the cable from being bent and causing wear between the upper fixing part 1 and the lower fixing part 2, thereby ensuring the safe operation of the cable.
