Description

Conductive rotating shaft structure

Technical Field

The utility model relates to an electrically conductive pivot structure especially relates to an electrically conductive pivot structure of being applied to on desk lamp.

Background

At present, all rotating parts of a lamp are conductive and rotary in a conductive rotating shaft mode; in a common conductive rotating shaft, the rotating shaft is designed into a hollow structure, and then an electric wire is penetrated to realize the function of rotating and conducting. However, this is done: on one hand, the diameter of the rotating shaft is increased, and the method is contrary to the lightness and thinness of the lamp products at present; on the other hand, the requirement of more than 360-degree rotation cannot be met by adopting a wire-conductive rotating shaft technology; meanwhile, due to frequent rotation, the wire is easy to be broken due to multiple twisting, so that the service life of the lamp is shortened. Therefore, a conductive hinge structure capable of solving the above problems is desired.

Disclosure of Invention

An object of the utility model is to overcome above-mentioned not enough, provide a convenient to use, the light and handy and long service life's of structure electrically conductive pivot structure.

The purpose of the utility model is realized like this:

a conductive rotating shaft structure comprises a metal shaft, wherein a plastic shell is sleeved on the metal shaft, a metal sleeve is sleeved on a connecting convex column which is formed by protruding one end of the metal shaft outwards, a connecting screw is screwed on the end face of the other end of the metal shaft, and a fastening piece is screwed on the end face of one end of the metal shaft, which is provided with the convex column.

The utility model relates to an electrically conductive pivot structure, one of plastic casing is close to the projection is served and is provided with the shoulder ring.

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

the metal shaft and the metal sleeve are in conductive connection, and the contact surface between the metal shaft and the metal sleeve is larger, so that the contact resistance is small, and the metal shaft can bear larger current, so that the metal shaft and the metal sleeve have wide application range; meanwhile, the metal shaft and the metal sleeve are connected in a rotating mode, the rotating shaft can rotate in all directions by more than 360 degrees while conducting electricity, and the metal shaft and the metal sleeve are in sliding contact with each other, so that compared with an internal cable penetrating mode, the design structure of the cable-free electric connector stops the possibility of rotating stranded wires or breaking; finally, particularly when the lamp body is of a metal construction, it can be matched perfectly by means of an insulating plastic housing fitted over the metal shaft, without additional insulation measures.

Fig. 2 is a schematic view of the conductive pivot structure according to the present invention.

Wherein:

a lamp body 101, a lamp arm 102;

metal shaft 1, plastic casing 2, metal covering 3, fastener 4, connecting screw 5.

Detailed Description

Referring to fig. 1 and 2, the utility model relates to a conductive rotating shaft structure, which comprises a metal shaft 1, wherein the metal shaft 1 is sleeved with a plastic shell 2, a connecting convex column formed by the convex of one end of the metal shaft 1 is sleeved with a metal sleeve 3, a connecting screw 5 is screwed on the end surface of the other end of the metal shaft 1, and a fastening piece 4 is screwed on the end surface of the end of the metal shaft 1 with the convex column;

furthermore, a shoulder ring is arranged at one end of the plastic shell 2 close to the convex column;

when the lamp is used, the metal shaft 1 is sleeved with the plastic shell 2 and then inserted into the jack of the lamp body 101, the shoulder ring on the plastic shell 2 is clamped on the jack, and the convex column is sleeved with the metal sleeve 3 and then inserted into the jack of the lamp arm 102, so that the integral conductive rotary connection is realized;

in addition: it should be noted that the above-mentioned embodiment is only a preferred embodiment of the present patent, and any modification or improvement made by those skilled in the art based on the above-mentioned conception is within the protection scope of the present patent.
