Detailed Description
The present invention will be described in detail with reference to the accompanying drawings 1-4 and the detailed description thereof.
A flexible contact net anchor rope fixing wire clamp comprises a first clamping plate 1, a second clamping plate 2, a connecting piece 3 and a bolt pair 4, wherein the first clamping plate 1 and the second clamping plate 2 are oppositely arranged, and two arc-shaped grooves 1-2 are respectively formed in the opposite surfaces of the first clamping plate 1 and the second clamping plate 2 along the line direction; the centers of the first clamping plate 1 and the second clamping plate 2 are both provided with through holes 1-1; the connecting piece 3 comprises a connecting plate 3-4, a through hole 3-1 is formed in the connecting plate 3-4, and two lugs 3-2 extend outwards from one end of the connecting plate 3-4; the double lugs 3-2 are provided with bolt pins 5 through hinge holes 3-3; the bolt pair 4 sequentially penetrates through the through hole 1-1 and the through hole 3-1 to fixedly connect the first clamping plate 1, the second clamping plate 2 and the connecting plate 3-4 together.
In one embodiment, the through holes 1-1 and the through holes 3-1 are two and correspond to each other vertically, the connecting plate 3-4 is of a U-shaped structure, the through holes 3-1 are located at the bottom of the U-shaped structure, and one end of each of two side walls of the U-shaped structure extends outwards to form two lugs 3-2. The inner surface of the arc-shaped groove 1-2 is provided with anti-slip teeth. The threaded end of the bolt pin 5 is sleeved with a nut 6, a cotter pin 7 is inserted in the radial direction, and the cotter pin 7 is positioned on the outer side of the nut 6.
