Abstract
The invention discloses a motor carbon brush holder which comprises a rectangular groove. Uprights are fixedly arranged at the long sides of the rectangular groove. A copper piece is buckled in the middle of the uprights. A round hole is formed in the middle of the copper piece. A spring capable of containing a carbon brush is vertically buckled below the round hole. The bottom of the spring is fixed on a wood block which is fixed on the bottom of the rectangular groove. Elastic force at the vertical direction of the spring is fixed, and therefore the carbon brush is protected and the motor is enabled to run normally.
Description
Technical field
The present invention relates to carbon brush holder, relate in particular to carbon brush frame for motor.
Background technology
Carbon brush holder is a kind of parts of placing for carbon brush.Leave certain interval between carbon brush and the carbon brush holder to guarantee that carbon brush can under the effect of spring force, slide in carbon brush holder.But the elastic force of spring is excessive or too small, all can affect the carbon brush normal operation.Therefore, need to provide a kind of new technical scheme to solve the problems referred to above.
Summary of the invention
The purpose of this invention is to provide a kind of carbon brush that holds, the carbon brush frame for motor that can play a protective role again.
The technical solution used in the present invention is:
Carbon brush frame for motor, it comprises the cuboid groove, the long side of described cuboid groove is fixed with column, described column middle part is connected with copper sheet, have circular hole in the middle of the described copper sheet, be connected with the spring that can hold carbon brush on the vertical direction of described circular hole below, described spring bottom is fixed on block of wood, and described block of wood is fixed in the cuboid trench bottom.
Described block of wood be shaped as circle.
The diameter of described block of wood is less than or equal to the length of cuboid groove width.
Beneficial effect of the present invention: carbon brush places in the spring; the copper sheet of fixing spring upper end is connected in the column middle part; block of wood of fixing spring lower end is positioned at the cuboid trench bottom; so the elastic force of spring in the vertical direction is certain; can be not excessive or too small; play the effect of protection carbon brush, so that motor runs well.
Description of drawings
Fig. 1 is structural representation of the present invention.
Wherein: 1, cuboid groove, 2, column, 3, copper sheet, 4, circular hole, 5, spring, 6, block of wood.
Embodiment
As shown in Figure 1, carbon brush frame for motor of the present invention, it comprises cuboid groove 1, the long side of cuboid groove 1 is fixed with column 2, and column 2 middle parts are connected with copper sheet 3, has circular hole 4 in the middle of the copper sheet 3, be connected with the spring 5 that can hold carbon brush on the circular hole 4 below vertical directions, spring 5 bottoms are fixed on circular block of wood 6, and block of wood 6 is fixed in cuboid groove 1 bottom, and the diameter of block of wood 6 is less than or equal to the wide length of cuboid groove 1.
Carbon brush places in the spring 5, and the copper sheet 3 of fixing spring 5 upper ends is connected in column 2 middle parts, and block of wood 6 of fixing spring 5 lower ends is positioned at cuboid groove 1 bottom; so the elastic force of spring 5 in the vertical directions is certain; can be not excessive or too small, play the effect of protection carbon brush, so that motor runs well.
