Abstract

The invention discloses an improved structure of an electric brush, which comprises a brush frame plate, a carbon brush component, a rotating shaft and a torsion spring. The rotating shaft consists of a lower shaft sleeved with the torsion spring and a upper shaft arranged with the carbon brush component, the diameter of the upper shaft is smaller than the diameter of the lower shaft, an installation end of the carbon brush component is connected with the upper shaft, an outer edge of the upper end face of the lower shaft is also provided with a lower bulge, and an outer wall on the lower part of the installation end of the carbon brush component is provided with an upper bulge which is jammed with the lower bulge when the carbon brush component is revolved outward. Therefore, when the electric brush is plugged with a commutator, the carbon brush component can only be rotated outward so that the lower bulge is jammed with the upper bulge. When the plugged installation is finished, the carbon brush component can be pulled up slightly to relieve the jamming. The carbon brush component can move back to the original position and are jointed with the commutator without the aid of any tooling, and the operation is very convenient.

Description

A kind of improved structure of electric brush
Technical field
The present invention relates to motor accessory field, relate in particular to motor brush.
Technical background
Brush is very extensive with application in exchanging series excited machine at direct current machine, and plays key effect.The applicant has applied for that on May 17th, 2006 name is called a kind of patent of invention of brush, notification number is CN2896613Y, it is simple in structure, reduced carbon brush and the mutual resistance of commutator, reduce noise, improved service behaviour, prolonged carbon brush useful life, but after it needs to adopt auxiliary mould with carbon brush outward turning location in assembling commutator process again with the commutator plug-in mounting, take out auxiliary mould then, carbon brush return and commutator clamping, operation is relatively more inconvenient like this.
Summary of the invention
Technical problem to be solved of the present invention just provides a kind of improved structure of electric brush, and it improves on original brush architecture basics, makes it need not use auxiliary mould when assembling with commutator, and is simple in structure, easy to assembly.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: a kind of improved structure of electric brush, comprise the brush holder plate, carbon brush component, rotating shaft and torsionspring, described rotating shaft is that symmetry axis vertically is located on the brush holder plate end face with brush holder plate centre bore axis, it is characterized in that: described rotating shaft comprises the lower shaft of suit torsion spring and the axle of going up of carbon brush component is installed, the described shaft diameter of going up is less than following shaft diameter, described torsionspring one end is fixedly connected on the lower shaft, the torsionspring other end is connected the carbon brush component stage casing, described carbon brush component installation end switching is on last axle, eaves also is provided with a lower convexity outside the upper surface of described lower shaft, described carbon brush component installation end bottom outer wall be provided with when the carbon brush component outward turning and described lower convexity blocking on the projection.
The guiding surface that acts on when preferably, described lower convexity is provided with the carbon brush component outward turning.
As preferably, described carbon brush is L shaped structure.
Another kind of preferred, described carbon brush is the yi word pattern structure.
The present invention is made as lower shaft and last axle with rotating shaft, and eaves is established a lower convexity the upper surface of lower shaft outside, when carbon brush component installation end bottom outer wall is provided with in the carbon brush component outward turning and described lower convexity blocking on protruding, like this, with the commutator plug-in mounting time, only need make lower convexity and epirelief play blocking the carbon brush component outward turning, when plug-in mounting is finished, stir carbon brush component on only needing slightly, remove blocking, carbon brush component is return and commutator clamping, need not by any frock, very convenient.
Description of drawings
Fig. 1 is an improved structure of electric brush structural representation of the present invention;
Fig. 2 is the plan structure schematic diagram of Fig. 1.
Embodiment
The present invention is described in further detail below in conjunction with accompanying drawing:
As Fig. 1, shown in 2, a kind of improved structure of electric brush of the present invention, comprise brush holder plate 1, carbon brush component 2, rotating shaft and torsionspring 3, described rotating shaft is that symmetry axis vertically is located on the brush holder plate end face with brush holder plate centre bore axis, described rotating shaft comprises the lower shaft 41 of suit torsion spring 3 and the upward axle 42 of carbon brush component 2 is installed, the described shaft diameter of going up is less than following shaft diameter, described torsionspring 3 one ends are fixedly connected on the lower shaft 41, the torsionspring other end is connected the carbon brush component stage casing, 21 switchings of described carbon brush component 2 installation ends are on last axle 42, eaves also is provided with a lower convexity 43 outside the upper surface of described lower shaft 41, described carbon brush component installation end 21 bottom outer walls be provided with when the carbon brush component outward turning and described lower convexity blocking on the projection 22, the guiding surface 431 that described lower convexity 43 acts on when being provided with the carbon brush component outward turning.Described carbon brush is L shaped structure or in-line structure.
