Description

Double-arm desk lamp

Technical Field

The utility model relates to a desk lamp of both arms structural style belongs to desk lamp technical field.

Background

At present, most desk lamps adopt a double-arm structure form for the stability of overturning, the electric conduction of the double-arm desk lamp adopts an electric wire penetrating into a shaft for conducting electricity, but the mode easily abrades an insulating skin outside the electric wire due to the relative rotation between the shaft and the electric wire, so that the service life of the desk lamp is influenced; therefore, a new conductive structure is needed to manufacture the dual-arm desk lamp.

Disclosure of Invention

An object of the utility model is to overcome above-mentioned not enough, provide a both arms desk lamp, its simple structure, convenient assembling.

The purpose of the utility model is realized like this:

a double-arm desk lamp comprises a lamp holder, a middle shaft, two lamp arms, a metal piece, a conductive sleeve and a conductive body, wherein the middle shaft penetrates through a shaft hole in the lamp holder, the two lamp arms are respectively rotatably sleeved at two ends of the middle shaft, the left end of the middle shaft is provided with the metal piece, the conductive sleeve is sleeved on the metal piece, and the conductive body sleeved in the lamp arms is in sliding contact;

the jackshaft is hollow structure, and is provided with on the axial wall of jackshaft and walks line hole one and spacing hole one, the sunken mounting groove that is formed with of lamp stand upper surface, be provided with on the cell wall of mounting groove and walk line hole one and spacing hole one that are linked together with the shaft hole, the one end of electric wire is connected on the metalwork, and the other end is worn out by walking line hole one and walking line hole two behind the hollow structure of jackshaft and is arranged in the mounting groove in, and the stopper is inserted simultaneously in spacing hole one and spacing hole two.

The utility model relates to a both arms desk lamp, a mounting has been put on the metalwork top spin of jackshaft left end.

The utility model relates to a both arms desk lamp, the jackshaft right-hand member has inserted the end cap.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses a conductive mode between arm and the jackshaft adopts the existing normal running fit conductive mode of this company, then combines the electric wire mode of drawing forth to draw forth the electric wire to the lamp stand in to make the assembly extremely convenient, and utilize the stopper to prevent the jackshaft rotatory, consequently guaranteed can not take place relative rotation between electric wire and the jackshaft, thereby can not cause the wearing and tearing of electric wire and buckle, be favorable to prolonging its life.
