Embodiment Construction

[0033] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0034] see figure 1 , the present invention provides a hand-cranked wire pipe threading device, which is used for threading the wire into the wire pipe pre-buried in the building. The construction progress also caused the problem of labor and material waste.

[0035] The hand-cranked wire conduit threading device of the present invention will be described below with reference to the accompanying drawings.

[0036] like figure 1 and figure 2 As shown, the hand-cranked wire conduit threading device of the present invention includes a metal wire 10 and an accommodating box 20 .

[0037] Wherein, the metal wire 10 is coiled into a spiral structure, the metal wire has a first end 11 and a second end located in the center of the spiral, and the first end 11 is formed with a spherical structure, which is used for reducing the pressure when the meta...

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 electric wire pipe threading device and a threading method thereof. Background technique [0002] In construction, the wire duct is usually pre-buried in the building, and then the wire is inserted into the wire duct after the construction is completed. However, the wire is relatively soft and it is difficult to directly penetrate the tortuous wire duct. At present, the common practice is to first use a ductile steel wire to penetrate into the wire tube, and then connect the wire at the end of the wire to bring the wire into the wire tube. [0003] However, even if a 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 wire to penetrate the wire tube smoothly. The two were responsible for pulling the steel wire out of the end of the wire tube,...
