DETAILED DESCRIPTION

[0018] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner, and thus only show components related to the present invention.

[0019] Please refer to Figure 1-4 A clamp for fixing power cables includes a substrate 1 and multiple cable clamp bodies 4 on the substrate 1. The cable clamp bodies 4 are detachably connected to the substrate 1, and the distance between each two adjacent cable clamp bodies 4 is adjustable. Since the distance is adjustable, the position of the cable clamp body 4 can be adjusted according to the cable laying position, thereby increasing the scope of application. The cable clamp body 4 includes multiple wire holes, and the inner wall of the wire hole is provided with an elastic insulating pad 5. Each wire hole corresponds to a cable, and the laying efficiency is high. The establishment of the elastic insulating pad 5 can effectively avoid the wear of the cable insulation layer.

[0020] Specifically, the surface of the substrate 1 is provided with a strip slide rail 2 along its length direction, and the bottom surface of the cable clamp body 4 is provided with a slide groove adapted to the strip slide rail 2. The cable clamp body 4 can move along the strip slide rail 2. After the cable clamp body 4 moves along the strip slide rail 2, its own position is adjusted and can be adjusted according to the cable laying position, which is highly practical.

[0021] The strip slide rail 2 is T-shaped, and the slide groove on the bottom surface of the cable clamp body 4 is in an inverted T-shape. The two have the same cross-section to meet the sliding requirements.

[0022] In this embodiment, the cable clamp body 4 includes a lower base 41, an intermediate base 42 and an upper base 43. The slide groove is provided on the bottom surface of the lower base 41. Angle irons 3 are provided on both sides of the lower base 41. The angle irons 3 are fixedly connected to the lower base 41. Bolts that abut the surface of the substrate 1 are provided on the angle irons 3. After the position of the cable clamp body 4 is determined, the bolts on the angle irons are rotated so that they are tightly abutted against the surface of the substrate 1, thereby preventing the cable clamp body 4 from undergoing secondary movement.

[0023] Furthermore, the surface of the lower base 41 is provided with a first screw rod 411 extending upward on both sides, and a plurality of first semicircular grooves 412 are provided between the two first screw rods 411. The intermediate base 42 is provided directly above the lower base 41, and the bottom surface of the intermediate base 42 is provided with a second semicircular groove 422 corresponding to the first semicircular groove 412, wherein the first semicircular groove 412 corresponds one-to-one to the second semicircular groove 422. The surface of the intermediate base 42 is provided with a third semicircular groove 423, the first screw rod 411 extends upward through the intermediate base 42, and second screw rods 421 are provided on both sides of the third semicircular groove 423. The second screw 421 extends upward through the upper base 43, and the bottom surface of the upper base 43 is provided with a fourth semicircular groove 431 that cooperates with the third semicircular groove 423.

[0024] Please refer again for details Figure 3-4 In this embodiment, the first semicircular groove 412 and the corresponding second semicircular groove 422 form a wire hole, and the third semicircular groove 423 and the fourth semicircular groove 431 form a wire hole. Multiple wire holes are formed in this way to meet the needs of laying multiple cables and are highly practical.

[0025] In addition, a fixing nut 45 is provided on each of the first screw rod 411 and the second screw rod 421 , and a surrounding compression spring 44 is provided below each of the fixing nuts 45 .

[0026] The intermediate base 42 and the upper base 43 can float upward simultaneously to compress the compression spring on the first screw 411; the upper base 43 can float upward to compress the compression spring 44 on the second screw 421; of course, the intermediate base 42 and the upper base 43 can also float separately.

[0027] The establishment of the compression spring 44 and the fixing nut 45 can allow the cable to float slightly in the wire hole, so that the cable has a certain amount of space to move, which can better adapt to strong winds or external force impact environments and avoid excessive tension on the cable.

[0028] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
