Rotating shaft of desk lamp

Abstract

The invention relates to the technical field of desk lamp parts, in particular to a rotating shaft of a desk lamp which comprises a first rotating shaft body, a second rotating shaft body and a locking piece, a first wire groove is concavely formed in one end of the first rotating shaft body, a first wiring pipe is arranged on the outer side wall of the first rotating shaft body, and a first threading hole communicating with the first wire groove is formed in the first wiring pipe; a rotating shaft cathode is convexly arranged in the first wire groove; a second wire groove is concavely formedin one end of the second rotating shaft body, a second wiring pipe is arranged on the outer side wall of the second rotating shaft body, a second threading hole communicating with the second wire groove is formed in the second wiring pipe, a rotating shaft anode corresponding to the rotating shaft cathode is convexly arranged in the second wire groove, and a damping piece is arranged between the rotating shaft anode and the rotating shaft cathode; and the magnitude of friction damping is changed by adjusting the compression amount of the rotating shaft anode and the rotating shaft cathode to the damping piece through the locking piece. The invention has the advantages that wires can be installed in wire grooves in the rotating shaft, exposure risks are avoided, the structure is simple, assembly and adjustment are convenient, threading efficiency is high, and cost is reduced.

Description

technical field [0001] The invention relates to the technical field of desk lamp components, in particular to a desk lamp rotating shaft. Background technique [0002] At present, most desk lamp shafts have many shortcomings, especially the internal wiring of the desk lamp is easy to interfere with the shaft, the internal threading is difficult, and the wires can only be exposed, which cannot meet the requirements of internal wiring and flexible rotation of the shaft at the same time. Moreover, the current common damping shaft has a complex structure, inconvenient installation and adjustment, and high cost. Contents of the invention [0003] In view of the above-mentioned shortcomings of the prior art, the object of the present invention is to provide a desk lamp shaft, which is used to solve the problems of difficult wiring inside the desk lamp shaft, complicated shaft structure, inconvenient installation and adjustment of damping between the shafts, and high cost in the ...
