A rotating shaft structure and a lamp with the rotating shaft structure

Abstract

The invention relates to a rotating shaft structure for assembling a rotating shaft and a shaft sleeve. The rotating shaft structure comprises a pipe shaft and a lubricating oil dropper, wherein an annular flange is arranged at a first end part of the pipe shaft, the outer diameter of the annular flange is larger than that of the pipe shaft, a plurality of opening troughs are formed in the end part of the annular flange, the annular flange is made of one of high-strength plastic cement or carbon fiber, a second end part of the pipe shaft is opened and is provided with a limiting flange, the annular flange and the limiting flange are used for limiting the shaft sleeve, the pipe shaft is hollow, and a plurality of first guide holes penetrating through a hollow part of the pipe shaft are formed in the outer wall of the pipe shaft; the lubricating oil dropper is contained in the inner cavity of the pipe shaft, a plurality of second guide holes matched with the first guide holes are formed in the side wall of the lubricating oil dropper, a polymeric membrane layer is paved on the outer wall of the lubricating oil dropper, and lubricating oil permeates to the outer wall of the pipe shaft by virtue of the second guide holes, the polymeric membrane layer and the first guide holes. By utilizing the rotating shaft structure, the installability, corrosion resistance and efficient lubricity of the rotating shaft structure are improved. Besides, the invention further discloses a lamp with the rotating shaft structure.

Description

technical field [0001] The invention relates to the lighting field, in particular to a rotating shaft structure and a lamp with the rotating shaft structure. Background technique [0002] The opening structure of lamps in the prior art all uses a metal rotating shaft, and the rotating shaft is fixed in the shaft sleeve by means of positioning pins or riveting. After long-term use, the positioning pins are easy to fall off, and riveting and disassembly are also difficult. At the same time, lubricating oil must be added to the surface of the metal shaft regularly. However, due to the small gap between the rotating shaft and the shaft sleeve, and the accumulation of dust between the rotating shaft and the shaft sleeve, it is difficult to add lubricating oil and the lubrication effect is difficult to guarantee. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a rotating shaft structure and a lamp with the rotating sh...
