Description
Technical field
The utility model relates to a kind of carbon brush shelf, is specifically related to a kind of for motor, can flexible, electromagnetism interference effective rotation carbon brush ring stand.
Background technology
Electric tool, such as hammer drill, electric drill, electric screwdriver etc., usually need to change direction of rotation to carry out operation, and traditional method is with an electric switch, changed the direction of rotation of instrument by the direction of switching current, and the brush device that has of motor can not be subjected to displacement.There is individual shortcoming like this, when regulating direction of rotation, the contact changed on switch is relied on to change direction of rotation, originally the electric current of up tool can be very large, and serious ablation contact also produces large spark, and then burn switch, and need in design to connect more circuit, and increase filter, electromagnetism anti-interference (EMI) does not go wrong to have the connector etc. of shielding properties to ensure, these measures cause the raising of production cost, otherwise will work the mischief to human body and social production activity.
Utility model content
For the problems referred to above, main purpose of the present utility model is to provide a kind of for motor, can flexible, electromagnetism interference effective rotation carbon brush ring stand.
The utility model solves above-mentioned technical problem by following technical proposals: a kind of rotation carbon brush ring stand, comprises base ring, the first metal steel loop, the second metal steel loop, some circle steel rings, some circle spacer rings and binding post; Described metal steel loop is fixedly centered around on pedestal; Described second metal steel loop is fixed on the periphery of the first metal steel loop by fixture; Gap is left between first metal steel loop and the second metal steel loop; Some circle steel rings are looped around on the second metal steel loop; Steel ring and spacer ring are spaced; One end of described base ring is connected with motor, and the other end is arranged on fixed support; One end that described base ring is connected with motor is fixed with described binding post.
In specific embodiment of the present utility model, the width of described steel ring and spacer ring is than being 5-2:1.
In specific embodiment of the present utility model, one end of described base ring is connected with motor by bolt.
In specific embodiment of the present utility model, one end that described base ring is connected with fixed support has groove, corresponding with the salient point on fixed support.
In specific embodiment of the present utility model, described spacer ring is nylon spacer ring.
In specific embodiment of the present utility model, one end that described base ring is connected with motor is fixed with a circle bakelite.
Positive progressive effect of the present utility model is: the rotation carbon brush ring stand that the utility model provides has the following advantages: the utility model is for motor, and electromagnetism interference is effective, easy for installation, good heat dissipation effect.
