Detailed Description
The present invention will be described in detail with reference to the accompanying drawings 1-5 and the detailed description thereof.
A universal feeder line supporting wire clamp comprises a wire clamp body 1, a pressing block 2 and a stud bolt 3, wherein two wire supporting grooves 1-2 are symmetrically arranged on the upper end face of the wire clamp body 1, first grooves 1-3 are symmetrically arranged on the outer walls of the two wire supporting grooves 1-2, a cylindrical table 1-1 extends downwards from the center of the lower end face of the wire clamp body 1, and a threaded hole 1-5 penetrating through the cylindrical table 1-1 is formed in the center of the wire clamp body 1; the pressing block 2 is arranged above the wire clamp body 1, the two wire pressing grooves 2-2 opposite to the wire supporting grooves 1-2 are symmetrically arranged on the lower end face of the pressing block 2, and the outer walls of the two wire pressing grooves 2-2 are located in the first grooves 1-3, so that the pressing block 2 is effectively prevented from rotating. The center of the pressing block 2 is provided with a through hole 2-1 which is coaxial with the threaded hole 1-5; the lower end of the stud bolt 3 penetrates through the through hole 2-1 to be in threaded connection with the threaded hole 1-5 and then extends out, and the upper end of the stud bolt is sleeved with the locking nut 4 to connect the wire clamp body 1 and the pressing block 2 together.
The upper end of the stud bolt 3 is further sleeved with a locking gasket 5, and the locking gasket 5 is located between the pressing block 2 and the locking nut 4. The anti-loosening gasket 5 is composed of a flat gasket and a spring gasket.
The wire clamp body 1 and the pressing block 2 are both copper alloy forgings and are integrally formed, so that the production period is short, the quality is reliable, and batch production is facilitated.
In one embodiment, anti-skid teeth are uniformly distributed on the inner surface of the wire pressing groove 2-2, so that the sliding load of the feeder line 7 in the use process is effectively increased.
In one embodiment, two ends of the wire supporting groove 1-2 are in a bell mouth shape 1-6. The friction between the feeder 7 and the wire supporting groove under the action of gravity in the using process is reduced.
