Description

Technical Field

[0001] This utility model relates to the field of wire connection technology, and in particular to a spacer bar for protecting wires. Background Technology

[0002] In overhead transmission lines, spacers serve to prevent whiplash between split conductors, suppress aerobatic vibrations, and reduce span oscillations. A spacer mainly consists of a frame and connecting clamps attached to the frame. The clamps grip the split conductors, and a limiting structure at the connection between the frame and the clamps allows the clamps to rotate a certain angle tangentially under the action of axial torsional force on the conductors.

[0003] Currently, the connection between the clamps and the frame in the spacer bar is simple and prone to damage after long-term use. When damaged, the entire bar needs to be replaced, which is costly. Utility Model Content

[0004] To address the above problems, this utility model provides a spacer bar that is simple in structure, convenient, and reliable for protecting wires.

[0005] The technical solution of this utility model is as follows: a spacer bar for protecting wires, comprising a frame body, a clamp body and a clamp cap. The frame body is hollow and has receiving grooves at all four corners. One end of the clamp body is installed in the inner corner of the frame body. A cross groove is provided at the top of the clamp body near one side edge. Fan-shaped support blocks are respectively provided around the middle of the cross groove. A cross shaft is provided inside the cross groove.

[0006] The top of the frame body has a through hole extending to the bottom, and the top of the cross shaft has a waist-shaped groove extending to the bottom. Rubber columns are provided above and below the multiple fan-shaped support blocks, and the multiple rubber columns are located at the recesses on the outer surface of the cross shaft.

[0007] A fitting bolt is provided between the inner walls of the waist-shaped groove. The bottom of the fitting bolt extends into the interior of the through hole, and the top and bottom of the fitting bolt are located at the top and bottom of the frame body.

[0008] One end of the wire clamp cover is rotatably connected to the wire clamp body, and both the inner side of the other end of the wire clamp cover and the inner side of the other end of the wire clamp body are provided with wire clamp rubber pads.

[0009] The other end of the clamp body is provided with a pivot, and the top and bottom of the pivot are installed in the limiting holes of the frame body.

[0010] The fitting bolt is equipped with a closed pin.

[0011] The limiting hole is an oblong hole.

[0012] In operation, this invention connects the clamp body to the frame body via rubber posts and a cross shaft. The cross shaft is secured within the cross groove using hardware bolts. When the connection between the clamp body and the frame body shakes, the cross shaft will also shake. The rubber posts cushion this shaking and their elasticity helps the cross shaft return to its neutral position. This combination of the cross shaft and rubber posts facilitates replacement and saves costs.

[0013] This invention is easy to process and reliable to operate. Attached Figure Description

[0015] The present invention will now be described in further detail with reference to the accompanying drawings.

[0016] like Figure 1-4 As shown in Embodiment 1, this utility model provides a spacer bar technical solution for protecting wires: it includes a frame body 1, a wire clamp body 2, and a wire clamp cover 3. The frame body 1 is hollow, and there are receiving grooves 8 on the upper and lower surfaces of the four corners. One end of the wire clamp body 2 is installed in the inner corner of the frame body 1. A cross groove 14 is provided on the top of the wire clamp body 2 near one side edge. Fan-shaped support blocks 12 are respectively provided around the middle of the cross groove 14. A cross shaft 6 is provided inside the cross groove 14.

[0017] In operation, when the clamp body 2 is connected to the frame body 1, it is connected via rubber posts 5 and a cross shaft 6. The cross shaft 6 is secured within the cross groove 14 by a metal bolt 7. When the connection between the clamp body 2 and the frame body 1 shakes, the cross shaft 6 will shake. The rubber posts 5 cushion the shaking of the cross shaft 6, and the elastic force of the rubber posts 5 helps the cross shaft 6 to return to its neutral position. The connection method using the cross shaft and rubber posts is flexible, adaptable to the operating environment of the wires, easy to replace, and low in cost.

[0018] The top of the frame body 1 has a through hole 9 extending to the bottom, and the top of the cross shaft 6 has a waist-shaped groove 10 extending to the bottom. Rubber posts 5 are provided above and below multiple fan-shaped support blocks 12, and the multiple rubber posts 5 are located in the recesses on the outer surface of the cross shaft 6. Hardware bolts 7 are provided between the inner walls of the waist-shaped groove 10. The bottom of the hardware bolts 7 extends into the through hole 9, and the top and bottom of the hardware bolts 7 are located at the top and bottom of the frame body 1. One end of the wire clamp cover 3 is rotatably connected to the wire clamp body 2. Wire clamp rubber pads 4 are provided on the inner side of the other end of the wire clamp cover 3 and the inner side of the other end of the wire clamp body 2. A rotating shaft 13 is provided on the other end of the wire clamp body 2. The top and bottom of the rotating shaft 13 are installed in the limiting hole 11 of the frame body 1. The hardware bolts 7 are provided with closed pins.

[0019] The clamp body 2 and clamp cover 3 are connected and fixed to the clamp rubber pad 4 by snap-fit, and the clamp body 2 and clamp cover 3 are hinged together to effectively solve the problem of the clamp rubber pad 4 falling out of the clamp body 2, thus reliably protecting the wire.

[0020] The limiting hole 11 is an oblong hole, which serves to limit the rotation of the shaft.
