Description
Technical field
The utility model relates to motor accessory technical field, especially a kind of adjustable length brush.
Background technology
The carbon brush of motor and the carbon brush of generator are referred to as carbon brush for electric machine or motor brush, and the appearance of carbon brush for electric machine is a little as wiping the rubber bar of pencil, and top has wire draw, volume varies.Existing brush lead is fixed between copper sheet and brush main body, length is fixed immutable, can only restringing for meeting need of work, cumbersome, and generally connect the mode of copper sheet for welding, due to vibrations during machine operation, copper cash can be made to rupture, cause brush unavailable, again change brush again.
Utility model content
In order to overcome existing above-mentioned deficiency, the utility model provides a kind of adjustable length brush.
The utility model solves the technical scheme that its technical problem adopts: a kind of adjustable length brush, comprise brush main body, wire and copper sheet, described copper sheet is fixed on brush main body upper end by two wires of bottom, the wire spool of positive and negative two direction of windings is provided with in described brush main body, wire spool superposition is placed, and share a rotating shaft, rotating shaft top is provided with rotating hoisting ring nut.
According to another embodiment of the present utility model, comprise described wire one end further and be fixed on brush body top, the other end is provided with self tapping swivel nut.
According to another embodiment of the present utility model, comprise further bottom described copper sheet and be provided with two screwed holes, screwed hole and self tapping swivel nut are connected.
According to another embodiment of the present utility model, comprise the described wire left and right sides near brush main body one end further and be equipped with guide plate.
The beneficial effects of the utility model are, conductor length can arbitrarily regulate, and the working stability that is threaded is firm, difficult drop-off, more not easy fracture, extend Service Life of Carbon Brush, cost-saving, increase operation rate.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
1. brush main body, 2. wire, 3. copper sheet, 4. wire spool, 5. rotating shafts, 6. rotating hoisting ring nut, 7. self tapping swivel nut, 8. screwed hole, 9. guide plate in figure.
Embodiment
If Fig. 1 is structural representation of the present utility model, a kind of adjustable length brush, comprise brush main body 1, wire 2 and copper sheet 3, described copper sheet 3 is fixed on brush main body 1 upper end by two wires 2 of bottom, the wire spool 4 of positive and negative two direction of windings is provided with in described brush main body 1, wire spool 4 superposes to be placed, share a rotating shaft 5, rotating shaft 5 top is provided with rotating hoisting ring nut 6, the length that rotating hoisting ring nut 6 can regulate two wires 2 is loosened by tightening, more adapt to work requirements, avoid the trouble changing brush time and again, described wire 2 one end is fixed on brush main body 1 top, the other end is provided with self tapping swivel nut 7, self tapping swivel nut 7 is installed need not tapping in advance, erecting tools can be directly used to be screwed in the reserved particular bore of mother metal, easy installation and removal, two screwed holes 8 are provided with bottom described copper sheet 3, screwed hole 8 and self tapping swivel nut 7 are connected, be threaded closely firm, described wire 2 left and right sides near brush main body 1 one end is equipped with guide plate 9, the link of fixing cord 2 and brush main body 1, prevent wire 2 from coming off.
Adjustable length brush lead length after improvement can arbitrarily regulate, and the working stability that is threaded is firm, difficult drop-off, more not easy fracture, extends Service Life of Carbon Brush, cost-saving, increases operation rate.
