[0028] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments.

[0029] Referring to Figures 1-4 , a cable protection cover comprises an arc-shaped bottom cover 1, opposite two side top surfaces of the arc-shaped bottom cover 1 are fixed with support plates 2, the support plates 2 are slidably connected with sliding plates 3, the top of the sliding plate 3 is fixed with an arc-shaped top cover 4, the arc-shaped top cover 4 and the opposite two side inner walls of the arc-shaped bottom cover 1 are both fixed with buffer springs 5, the bottom of the buffer spring 5 is fixed with an arc-shaped buffer plate 6, the inner wall of the arc-shaped buffer plate 6 is bonded with wear-resistant pads 7; the surface wear-resistant layer of the wear-resistant pad 7 is specially treated, has high wear resistance, can effectively reduce friction and wear, can maintain its integrity in long-term use, and the wear-resistant pad 7 has a certain elasticity, can absorb and disperse impact energy.

[0030] The cable protection cover further comprises a limiting piece, and the limiting piece is used for limiting the sliding of the sliding plate 3.

[0031] In the embodiment, as shown in Figure 1 , Figure 2 and Figure 3 , the limiting piece comprises a screw 21, a pull rod 22, an insertion hole 31 and a threaded strip 32, the screw 21 is threadedly connected on the support plate 2, the pull rod 22 is fixed on the screw 21, the insertion hole 31 is formed on the sliding plate 3, the insertion hole 31 is linearly distributed and has a plurality of insertion holes, and the threaded strip 32 is arranged on the inner wall of the insertion hole 31, so that when the screw 21 is inserted into the insertion hole 31, the screw 21 can be tightly matched and connected with the threaded strip 32, the screw 21 or the threaded rod can be prevented from loosening or falling off when subjected to external force, and thus the stability and reliability of the connection are enhanced.

[0032] In the embodiment, as shown in Figure 2 , the support plate 2 is hollow inside, a compression spring 33 is fixed on the inner top surface of the support plate 2, the compression spring 33 is provided with a mounting space, and the compression spring 33 is linearly distributed, so that the compression spring 33 can be uniformly distributed and stably work when subjected to external force, and local overload or damage is avoided. The top of the compression spring 33 is fixedly connected with the bottom surface of the sliding plate 3.

[0033] In the embodiment, as shown in Figure 1And Figure 2 As shown in the figure, the top surface of the support plate 2 is provided with a groove for facilitating the sliding of the sliding plate 3. The groove can reduce the frictional resistance between the sliding plate 3 and the support plate 2, so that the sliding plate 3 can slide more smoothly and stably. The support plate 2 and the sliding plate 3 are symmetrically arranged about the axis of the arc-shaped bottom cover 1 and the arc-shaped top cover 4. This can ensure that the sliding plate 3 remains balanced and stable during sliding, while reducing additional friction and wear caused by asymmetry.

[0034] In this embodiment, as shown in the figure, Figure 4 The screw 21 is threadedly connected with the threaded strip 32.

[0036] The function principle of the utility model can be described by the following operation mode:

[0037] When the arc-shaped bottom cover 1 is used, first, the installation interval is adjusted according to the specification of the cable, the pull rod 22 is rotated to drive the screw 21 to rotate in the support plate 2, the screw 21 is then rotated outward to disengage from the insertion hole 31 on the sliding plate 3, thereby releasing the limitation of the sliding plate 3, and then the arc-shaped top cover 4 is pulled up to be stressed and slide up in the support plate 2. In this process, the compression spring 33 is stretched to provide the required support force for the arc-shaped top cover 4. When the arc-shaped top cover 4 reaches the appropriate height, the screw 21 and the corresponding insertion hole 31 are on the same horizontal plane, the pull rod 22 is rotated again to drive the screw 21 to rotate forward. The screw 21 is threadedly connected with the threaded strip 32 in the insertion hole 31 during rotation, gradually embedded and clamped into the insertion hole 31 on the other side of the sliding plate 3, thereby achieving the reinforcement and locking of the sliding plate 3. After adjustment, the cable is inserted between the arc-shaped bottom cover 1 and the arc-shaped top cover 4, and the cable is placed in contact with the arc-shaped buffer plate 6. The arc-shaped buffer plate 6 is stressed and pressed against the buffer spring 5, and the buffer spring 5 uses its own elastic properties to buffer the extrusion force generated when the cable is extruded. When the cable is completely placed, the buffer spring 5 will reset and adhere to the surface of the cable. At this time, the wear-resistant pads 7 on the inner wall of the arc-shaped buffer plate 6 will be tightly attached to the two sides of the cable to provide additional protection, avoiding friction and wear between the cable and the protective cover due to external shaking during use.
