Hand-operated electric wire pipe threading device and its threading method

Abstract

The invention relates to a hand-operated wiring tube threading device and a threading method thereof. The threading device comprises a metal wire coiled as heliciform, wherein the metal wire has a first end and a second end, and a sphere structure is formed at the first end; a holding box for placing the metal wire, wherein an outlet from which the first end of the metal wire extends out is formedat the bottom of the holding box, and a rotatable hand-operated handle is arranged in the holding box; the metal wire is wound on the hand-operated handle, the contracting and releasing of the metalwire is controlled by rotating the hand-operated handle; the first end of the metal wire extends out from the outlet and extends in one end of the wiring tube till to extend out from the other end when the hand-operated handle is rotated to release the metal wire, and then the electric wire bound and connected on the metal wire is driven to penetrate the wiring tube. The end part of the metal wireis made as the sphere structure so that the metal wire can smoothly stretch into the wiring tube, thereby driving the electric wire to penetrate the wiring tube; and the material and the manpower aresaved.

Description

technical field [0001] The invention relates to the technical field of building electrical construction, in particular to a hand-operated wire pipe threading device and a threading method thereof. Background technique [0002] In building construction, wire tubes are usually pre-buried in the building, and the wires are inserted into the wire tubes after the construction is completed. However, the wires are relatively soft, and it is difficult to directly penetrate into the tortuous wire tubes. The current common practice is to first utilize ductile steel wires to penetrate into the electrical conduits, and then connect the wires at the tails of the steel wires to bring the electrical wires into the electrical conduits. [0003] However, even if the ductile steel wire is used, due to the frictional resistance between the end of the steel wire and the wall of the wire tube, it is difficult for the steel wire to penetrate the wire tube smoothly. The two were responsible for p...
