DETAILED DESCRIPTION

[0020] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] An embodiment of the present utility model, as Figure 1 As shown, a purlin fixing plate 3 is provided at the bottom of the main shaft 2 and is installed in the same direction as the purlin 1. The purlin 1 and the purlin fixing plate 3 are fixed on the upper and lower sides of the main shaft 2 by bolts 4 provided on both sides of the main shaft 2. A wire clamp 5 is installed on the surface of the bolt 4. The wire clamp 5 is made of wound steel wire, which requires less material, has high strength, low cost and beautiful appearance. A cable 6 is provided in the wire clamp 5 and is installed in the same direction as the main shaft 2. The original structure of the bracket is not changed, no additional installation position needs to be reserved, no on-site drilling is required, and the compatibility is good.

[0022] like Figure 2As shown, the wire clamp 5 includes an upper buckle 51 and a lower buckle 52 arranged from top to bottom. The upper buckle 51 is connected to the lower buckle 52 through a vertically arranged first steel wire segment 54. A cable clamp 53 is provided at the bottom of the lower buckle 52.

[0023] The cable clamp 53 is a closed area consisting of a wavy card slot and a vertically arranged second steel wire segment 55. As a preferred embodiment of the present application, four groups of wavy card slots are arranged in the vertical direction. The number and size of the wavy card slots can be increased or decreased according to the requirements of the number and diameter of cables, and the scalability is strong.

[0024] A hook 56 is provided at the top of the second wire segment 55 near the lower buckle 52. The hook 56 and the cable clamp 53 form a fixed structure to clamp the cable. The installation method of the buckle and the hook is simple to install and easy to operate.

[0025] The upper buckle 51 and the lower buckle 52 have opposite opening directions. Both the upper buckle 51 and the lower buckle 52 are horizontal arc structures formed by bending steel wire. Force is applied on both sides of the bolt 4 to ensure that the wire clamp can be stably clamped on the bolt 4.

[0026] A gap is provided between the main shaft 2 and the wire clamp 5 , and the upper buckle 51 of the wire clamp 5 passes through the gap and is fastened and installed on the upper part of the bolt 4 , so that the upper buckle 51 passes through the gap and is fastened on the surface of the bolt 4 .

[0027] Working Principle: The wire clamp is made of wound steel wire and has two buckles, one facing up and one facing down. After the bolt, purlin, and spindle are installed, a gap is formed. The upper buckle of the wire clamp passes through the gap and buckles onto the upper part of the bolt. The lower buckle uses the cylindrical surface of the bolt to hold the bolt tightly. This ensures that the wire clamp is firmly attached to the bolt and will not slide as the spindle rotates. When installing the cable, separate the cable clamp at the bottom of the wire clamp at a certain angle and place the cable inside. The wire clamp uses its own elasticity and the hook structure in the middle to form a solid connection, securing the cable. The number of cable clamps can be increased as needed.

[0028] Several points that need to be explained are: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, which can be mechanical connection or electrical connection, or internal communication between two elements, or direct connection. "Up", "down", "left", "right" and the like are only used to indicate relative position relationships. When the absolute position of the described object changes, the relative position relationship may change; secondly, in this article, relational terms such as first and second are only used to distinguish one entity from another, and do not necessarily require or imply that there is any such actual relationship or order between these entities.

[0029] The above examples are merely illustrative of the present invention and do not limit the scope of protection of the present invention. Any design that is identical or similar to the present invention falls within the scope of protection of the present invention.
