Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the present invention will be further described in detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1-4, a universal wire pressing pipe for a ground wire comprises a pipe body 1 and an extruding mechanism for extruding the pipe body 1, wherein a section of solid reinforcing column 2 is arranged in the middle of the pipe body 1, a plurality of arc-shaped grooves 3 are axially arranged on the inner wall of the pipe body 1, in the embodiment, the reinforcing column 2 part of the pipe body 1 has certain strength, the pipe body 1 parts on two sides of the reinforcing column 2 are copper pipes, the arc-shaped grooves 3 can be the direct arc-shaped surfaces of the copper pipes, and simultaneously, openings 14 extending along the axial direction are arranged on the side walls of the pipe body 1 and the reinforcing column 2;

the extrusion mechanism comprises pressing assemblies for extruding and fixing two ends of the pipe body 1, each pressing assembly comprises a clamp body 4, notches 7 are formed in an upper pressing head 5 and a lower pressing head 6 of each clamp body 4, namely the upper pressing head 5 and the lower pressing head 6 of each clamp body 4 are of U-shaped structures, the pipe body 1 is placed between the upper pressing head 5 and the lower pressing head 6, and the reinforcing columns 2 are located in the notches 7;

the extrusion mechanism further comprises a rotating member (not shown in the figures) for rotating the reinforcing column 2, the rotating member rotates the tube 1 after the tube 1 is pressed on the pressing assembly, in this embodiment, the rotating member preferably adopts a wrench, and the reinforcing column 2 is a polygonal column; the pipe body 1 is placed between an upper pressure head 5 and a lower pressure head 6 of a clamp body 4, the clamp body 4 is pressed, the end part position of the pipe body 1 is tightly pressed on the surface between the upper pressure head 5 and the lower pressure head 6, then a rotating piece (a wrench) penetrates through a gap 7 to be connected with a reinforcing column 2, the rotating piece is rotated to further rotate the pipe body 1, the pipe body 1 is subjected to rotational deformation, namely, the end part of a grounding wire is screwed on the pipe body 1 through the pipe body 1, the grounding wire is usually a stranded wire and is matched with an arc-shaped groove 3 of the pipe body 1, and after the pipe body 1 is subjected to rotational deformation, the grounding wire and the pipe body 1 form similar threaded fit, so that the pipe body is; and the operation is completed at one time, repeated operation is not needed, and the operation is convenient.
