Abstract

A universally-rotary conductive device comprises a first shell having a straight rod. An internal surface of the shell is provided with grooves. The grooves are completely provided with first metal filaments. An external surface of a second shell is provided with projections corresponding to the grooves in the first shell. The projections are completely provided with second metal filaments. An internal surface of the second shell is also provided with grooves, and the grooves are completely provided with third metal filaments. The second shell is sleeved in the first shell. The first shell and the second shell are rotary relatively. A ball body is sleeved in the second shell. The surface of the ball body is provided with projections corresponding to the grooves in the second shell, and the projections are completely provided with fourth metal filaments. According to the universally-rotary conductive device, the grooves and the projections are arranged on the first shell, the second shell and the ball body in a cooperated manner and are provided with the metal filaments, so that the universally-rotary conductive device achieves multi-direction rotation and electrical conduction.

Description

A kind of universal rotary type electric installation
Technical field
The utility model relates to a kind of electric installation, is specifically related to a kind of electric installation that can universal rotational.
Background technology
Mostly be conducting slip ring relating to existing technical scheme while realizing power supply to different azimuth, its principle is to be nested with one heart with sound two rings, and forming in plane can 360 degree rotation or the slip ring structures of linear slide; Utilize between rotating ring and stationary ring on slideway simultaneously, with conductive wire or the reliable contact mutually of carbon brush and conducting electricity.This technical scheme can only be applicable to the more single situation of relative motion between inlet wire and outlet, for example: only need can rotate relative to 360 degree between line, or only need energy relative sliding between line.
If run into the motion that relative motion between line exists 2 or 3 directions simultaneously, can not effectively solve, must to be used in combination a plurality of, multiple conducting slip ring.Adopt such form that is used in combination, can cause terminal to increase and the stack of stability decreases, structure is installed and compactedness reduces.
Summary of the invention
For the deficiencies in the prior art, the purpose of this utility model is to provide a kind of universal rotary type electric installation, and this device can be realized when relative motion between line exists the motion of 2 or 3 directions simultaneously still can guarantee reliable power supply.
The purpose of this utility model is achieved in that a kind of universal rotary type electric installation, comprises first housing with straight-bar, and shell inner surface is provided with groove; In groove, be covered with the first metal fibril, the outer surface of the second housing is provided with the projection corresponding with groove on the first housing, in projection, be covered with the second metal fibril, in the second shell inner surface, be also provided with and groove, in groove, be covered with the 3rd metal fibril, the second housing is sleeved in the first housing, between the first housing and the second housing, can relatively rotate; Spheroid is sleeved in the second housing, at spherome surface, is provided with the projection relative with the second surface of shell groove, is covered with the 4th metal fibril in projection.
The groove of the second shell inner surface becomes 90 degree angles with the groove of the first shell inner surface.
The universal rotary type electric installation that the utility model provides, by the groove and projection cooperatively interacting is set on the first housing, the second housing and spheroid, and in groove and projection, lay the structure of metal fibril, make electric installation realize multidirectional rotation and conduction.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the first shell structure schematic diagram of the present utility model.
Fig. 3 is the second housing outer surface figure of the present utility model.
Fig. 4 is the second shell inner surface figure of the present utility model.
Fig. 5 is sphere structure schematic diagram of the present utility model.
Embodiment
Structure of the present utility model is as Figure 1-5: a kind of universal rotary type electric installation, is characterized in that: comprise first housing 2 with straight-bar 1, housing 2 inner surfaces are provided with groove; In groove, be covered with the first metal fibril 3, the outer surface of the second housing 4 is provided with the projection corresponding with groove on the first housing 2, in projection, be covered with the second metal fibril 5, at the second housing 4 inner surfaces, be also provided with and groove, in groove, be covered with the 3rd metal fibril 6, the second housing 4 is sleeved in the first housing 2, between the first housing 2 and the second housing 4, can relatively rotate; Spheroid 7 is sleeved in the second housing 4, is provided with the projection relative with the second housing 4 surface grooves on spheroid 7 surfaces, is covered with the 4th metal fibril 8 in projection.The groove of the second housing 4 inner surfaces becomes 90 degree angles with the groove of the first housing 2 inner surfaces.
Operation principle of the present utility model is as follows:
As shown in drawings, this device is mainly divided into three parts i.e. the first housing 2, the second housing 4 and spheroid 7, spheroid 7 is sleeved in the second housing 4, between the first housing 2 and the second housing 4, leave gap, like this, between spheroid 7 and the first housing 2, can in a cone space, relatively move, can conduct electricity, concrete methods of realizing is as described below simultaneously:
The first housing 2 is spherical shells that are slightly larger than hemisphere with straight-bar 1 and integral body, and its inner surface is fluted, is covered with the first metal fibril in groove; The second housing 4 is integrated the long-pending spherical shell that is slightly less than the first housing 2, its outer surface has the projection corresponding with 2 grooves of the first housing, in projection, be covered with the second metal fibril, after the first housing 2 and the second housing 4 assemblings, can realize the relative sliding in horizontal plane.Meanwhile, during slip, two metal fibrils are in contact with one another, and can realize the conduction of 4 of the first housing 2 and the second housings.
The inner surface of the second housing 4 has the groove similar with the first housing 2 inner surfaces, and its direction becomes 90 degree angles with the groove of the first housing 2, is covered with equally metal fibril, i.e. the 3rd metal fibril 6; Spheroid 7 is the whole spheroid with straight-bar that a volume is slightly less than the second housing 4, its outer surface has the projection corresponding with the second housing 4 inner surface recesses, and is covered with metal fibril, i.e. the 4th wire 8, the second housing 4 can be realized the relative sliding in vertical plane after assembling with spheroid 7.Meanwhile, during slip, metal fibril is in contact with one another, and can realize the conduction of 7 of the second housing 4 and spheroids.
This installs after whole combination completes, and between the first housing 2 and spheroid 7, can, by conduction transmission and the motion stack of the second housing 4, realize conduction and being free to slide in all directions.
The relative sliding conductivity principle of the metal fibril in the utility model is existing mature technology, and reliable conduction guarantee can be provided.
