Tighten positioning bolt

Abstract

The invention discloses a tightening positioning bolt, which comprises two steel wire positioning bolts (1) with internal thread, at least two double-end studs (4) with tightening nuts (2) at both ends and at least an internal thread positioning bolt (2). Both ends of the internal thread positioning bolt (3) are provided with internal threads, and the internal threads of the internal thread positioning bolt (3) are respectively screwed with the external threads of two double-end studs (4) at each end; the external threads of the end, away from the internal thread positioning bolt (3) of the double-end stud (4) are respectively screwed with the internal threads of two steal wire positioning bolts (1); the external end plant of the steel wire positioning bolts (1) are provided with through holes (5) for passing the steel wires, and the internal ends of the through holes of the steel wire positioning bolts (1) are provided with an internal cavity (6) for containing a steel wire heading with a diameter larger than that of the through holes (5). The tightening positioning bolt of the invention has the advantages of large bolt adjusting amplitude, good fastening effect, and flexible and convenient assembly and disassembly.

Description

technical field [0001] The invention relates to a fastener, in particular to a tightening positioning bolt used for pull-ups on utility poles and the like. Background technique [0002] Compression positioning bolts are widely used in industrial, civil, decoration and other fields, mainly used for fastening utility pole pulls and so on. Most of the fasteners used in the prior art for fastening utility pole pulls are internally threaded positioning bolts with hooks screwed at both ends. One end hook hooks the steel wire, and the other end hook hooks on the buried ring or on the hook. [0003] There are following defects in the fastener of above structure: [0004] 1. If the internal threads at both ends of the internal thread positioning bolt are in the same direction, the fastener cannot be adjusted at all, and the tightness of the steel wire cannot be adjusted by the relative rotation of the hook and the internal thread. If the internal threads at both ends of the intern...

AI Technical Summary

Problems solved by technology

However, due to the short adjustment distance of the internal thread positioning bolt, it is impossible to greatly adjust the tightness of the steel wire. Therefore, once the deformation of the steel wire exceeds the adjustment amount of the fastener due to excessive use, the effect of fixing the object cannot be achieved.

[0005] 2. Since the fastener has no adjustment distance or the adjustment distance is limited, when installing the fastener, the steel wire must be tightened with a mechanical tensioner, and the hook at one end of the fastener must be passed through the hook at the other end. Hook on the buried hook or ring, and then clamp the steel wire with wire crimping pliers. The tensioning process is very laborious, which makes the installation process very cumbersome

[0006] 3. Since the steel wire has been clamped to death, when disassembling, you have to find a tool to cut the steel wire to remove the fastener. The disassembly process is very inconvenient
