Specific embodiment
In order that those skilled in the art more fully understand technical scheme, the present invention is entered below in conjunction with the accompanying drawings
Row is described in detail, and the description of this part is only exemplary and explanatory, should not there is any restriction to protection scope of the present invention
Effect.
As Figure 1-Figure 4, concrete structure of the invention is：It is a kind of to keep the Novel electric brush of contact to fill based on centrifugal force
Put, including rotating shaft 1, outer sleeve body 2 and slide block 3, the rotating shaft 1 is arranged inside outer sleeve body 2, and is assembled for coaxial；The cunning
Block 3 is spindle rotationally arranged between outer sleeve body 2 and rotating shaft 1, and the upper end of slide block 3 and rotating shaft 1 is electrically connected by flexible cord；The slide block
3 two ends are provided with the guide rail 21 for depending on outer sleeve body 2；The rotating shaft 1 be radially arranged promote slide block 3 move in a circle it is convex
Plate 11；Flange 11 causes slide block 3 to be synchronized with the movement with rotating shaft, makes device keep contact conducting well.
Preferably, the slide block 3 is arc.
Preferably, the uniform intervals of the flange 3 are distributed in the surface of rotating shaft 3, adjacent flange（11）Interval be provided with cunning
Block（3）.
Preferably, slide block 3 and rotating shaft 1 is electrically connected by the flange 11 being arranged in rotating shaft 1；Guarantee good contact conducting
Effect.
Preferably, the surface of the rotating shaft 1 is additionally provided with boss 4.
Preferably, the rotating shaft 1 and the homogeneous phase of flange 11 are away from distribution, the length of its spacing distance slide block 3.
Preferably, the inner upper end of the boss 4 is drawn in be provided with the endoporus 42 of lower end expansion, the endoporus 42 and up and down may be used
The projection 43 of activity, the lower end of the projection 43 is embedded in endoporus 42, and upper end is extended to outside endoporus, it is ensured that projection is on endoporus 42 is interior
Lower activity is without deviating from.
Preferably, the bottom of the projection 43 is connected by spring 41 with the inwall of boss 4.
Preferably, what the top of the projection 43 was embedded is provided with balancing weight 44 so that when rotated, the upper end of projection 43 is received
Bigger centrifugal force, stretches out more smooth.
Preferably, this device can coordinate with other brushgears and use simultaneously.
When specifically used, when rotating shaft 1 is static, always there is a slide block 3 to be close to outer sleeve body 2 by self gravitation；When rotating shaft 1
During rotation, flange 11 follows rotation, and so as to promote slide block 3 according to the direction of rotation seat circular motion of rotating shaft 1, slide block 3 is doing circumference fortune
When dynamic, because of the effect of centrifugal force so that slide block 3 is firmly adjacent to conductor 2 and slides in guide rail 21, and when rotating speed is higher, it is received
The centrifugal force for arriving is bigger, fits tighter, is particularly suited for high speed conditions.After rotating shaft 1, boss 4 also follows rotation, in it
The projection 43 and balancing weight 44 in portion is outwards skidded off because of centrifugal force, is deformed spring；After projection 43 is skidded off, extend to
At the 3/4 of the height of slide block 3, so, in variable-speed operation, anti-limited slip block 3 produces speed difference with flange 11, in the work of inertia
Lower separation is used, and affects the operation of device；After rotating shaft shuts down, projection 43 resets under the pulling force of spring 41, now
Slide block 3 is moved freely, and is convenient for changing.
