[0021] The following is combined with Figure 1-3 , the specific implementation of the utility model is described in detail, but it should be understood that the protection scope of the utility model is not limited by the specific implementation. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0022] The cable clamp provided by the utility model comprises an upper clamp and a lower clamp, wherein an arc-shaped accommodating groove 2 is provided in the middle of the side where the upper clamp and the lower clamp are close to each other, inner serrations 7 are provided on the left and right sides of the lower clamp, and a side wall 4 is respectively provided on the left and right sides of the lower side of the upper clamp, and the side wall 4 can be elastically bent, and outer serrations 6 are provided on the side where the two side walls 4 are close to each other, and the inner serrations 7 are engaged with the outer serrations 6 to limit the upper clamp and the lower clamp from moving away in the vertical direction, and a quick-release buckle hand groove 5 is also provided on the side where the side walls 4 are close to each other, and the quick-release buckle hand groove 5 is located at the end of the corresponding side wall 4 away from the upper clamp, specifically, the upper clamp is made of a material with a certain rigidity and elasticity, and more specifically, the top or side wall 4 of the upper clamp is made of a material with a certain rigidity and elasticity. The material, as an example, can be a plastic material or a thin metal material with a certain rigidity and elasticity, so as to achieve a stable engagement between the inner serrations 7 and the outer serrations 6, and when subjected to a certain lateral force, the side wall 4 can bend outward. By adopting the above technical solution, the upper clamp and the lower clamp are forced to squeeze each other so that the inner serrations 7 and the outer serrations 6 are engaged with each other, and the clamp can be quickly installed. By providing a quick-release buckle hand groove 5 on the side wall 4, the side wall 4 can be bent by pinching the quick-release buckle hand groove 5 to open it outward, so that the outer serrations 7 and the inner serrations 6 of the upper clamp and the lower clamp can be separated, and then the upper clamp can be separated from the lower clamp, thereby achieving rapid separation of the clamps, which can effectively improve the efficiency of inspection and disassembly of the clamps.

[0023] As a preferred embodiment, a quick-release reserved hole 1 is respectively provided on the left and right sides of the upper clamp, and a quick-release guide surface 8 is respectively provided on the left and right sides of the lower clamp. The axis of the quick-release reserved hole 1 and the quick-release guide surface 8 are parallel to the wall surface of the side wall 4 where the outer serrations 6 are located. The quick-release guide surface 8 and the side wall 4 close to it are respectively located on the opposite sides of the axis of the quick-release reserved hole 1, so that the quick-release tool can be inserted from the quick-release reserved hole 1 between the corresponding quick-release guide surface 8 and the side wall 4. By adopting the above technical solution, the quick-release tool can be quickly inserted between the quick-release guide surface 8 and the side wall 4 through the quick-release reserved hole 1, so that the side wall 4 is elastically bent, thereby separating the outer serrations 6 on the side wall 4 from the corresponding inner serrations 7, thereby improving the disassembly speed of the clamp.

[0024] As a preferred embodiment, the quick-release tool includes a flat-blade screwdriver or a sheet-like hard object. By adopting the above technical solution, the flat-blade screwdriver or the sheet-like hard object can be easily inserted into the quick-release guide surface 8, thereby increasing the disassembly speed.

[0025] As a preferred embodiment, two groups of inner serrations 7 are provided on the left and right sides of the lower clamp, and are respectively located on both sides of a quick-release guide surface 8, and two groups of outer serrations 6 are provided on the two side walls 4, and the outer serrations 6 correspond to the inner serrations 7 one by one, and the outer serrations 6 and the corresponding inner serrations 7 are engaged with each other. By adopting the above technical solution, a quick-release tool inserted from the quick-release reserved hole 1 to the quick-release guide surface 8 and the side wall 4 can separate the two groups of outer serrations 6 located on the same side from the corresponding inner serrations 7 at the same time, thereby avoiding incomplete separation of the outer serrations 6 and the inner serrations 7.

[0026] As a preferred embodiment, two guide limit plates 12 are respectively provided on the sides close to each other on the two side walls, and the two guide limit plates 12 on the same side are respectively located on the front and rear sides of the upper clamp, and the left and right sides of the front and rear walls of the lower clamp are provided with guide limit grooves 13 adapted to the guide limit plates 12. By adopting the above technical scheme, through the guide limit plates 12 and the guide limit grooves 13, the positions of the upper clamp and the lower clamp can be aligned when installing them to avoid the outer serrations 6 and the inner serrations 7 thereon from not being able to fully engage. At the same time, the lower clamp is restricted between the guide limit plates 12 by the guide limit plates 12 to avoid lateral sliding and misalignment.

[0027] As a preferred method, a bolt hole 9 is longitudinally penetrated through the middle of the lower clamp, and the bolt hole 9 is arranged in a recessed groove close to one end of the upper clamp. By adopting the above technical solution, the cable clamp can be fixed at the required installation position through the bolt hole 9 using a fixing bolt, while avoiding the fixing bolt from pressing against the cable, causing damage to the cable.

[0028] As a preferred method, a plurality of water holes 10 are provided on the side of the lower clamp away from the upper clamp. The water holes 10 are parallel to the arc center line of the arc-shaped receiving groove 2. The water holes 10 are arranged in a trapezoidal shape. By adopting the above technical solution, the water holes 10 can facilitate the passage of water, avoid erosion of the cable, and reduce the risk of cable damage.

[0029] As a preferred embodiment, there is one arc-shaped receiving groove 2 on the upper clamp and two arc-shaped receiving grooves 2 on the lower clamp. Since cables generally adopt a herringbone arrangement structure, the above technical solution can better accommodate the herringbone arranged cables, and two arc-shaped receiving grooves 2 are arranged on the lower clamp, which can increase the support area for the cables and reduce the risk of cable damage.

[0030] As a preferred method, two long bolt holes 11 are longitudinally penetrated on the lower clamp, and the long bolt holes 11 are respectively located on both sides of the arc-shaped accommodating groove 2. By adopting the above technical solution, both ends of the lower clamp can be fixed by long fixing bolts through the long bolt holes 11, thereby improving stability.

[0031] As a preferred embodiment, two bolt avoidance holes 3 are provided on the upper clamp, and the bolt avoidance holes 3 correspond to the long bolt holes 11 one by one. The bolt avoidance holes 3 are coaxially arranged with the corresponding long bolt holes 11, and the bolt avoidance holes 3 are connected in parallel with the quick-release reserved holes 1. The quick-release reserved holes 1 are flatly arranged and parallel to the quick-release guide surface 8. The above technical scheme is adopted to facilitate the installation of long bolts on the long bolt holes 11. At the same time, since the bolt avoidance holes 3 are connected in parallel with the quick-release reserved holes 1, the volume of the utility model can be reduced. When the quick-release tool is inserted into the quick-release reserved holes 1 and reaches between the quick-release guide surface 8 and the side wall 4, the quick-release tool can have a certain movable space in the bolt avoidance hole 3.
