Description
Technical field
The utility model is related to brush technique field, is specially a kind of elastic adjustable brush structure.
Background technology
Brush is the device that energy or signal are transmitted between motor or the fixed part and running part of generator, motor
When rotating, electric energy is sent to coil by commutator, but brush is attached thereto after long-time is used and is worn
The elasticity decrease of spring, causes brush and commutator loose contact, causes the appearance of electric spark, or even can cause the damage of motor
It is bad, brush can only so be changed, brush is not used fully, cause the waste of resource.
Utility model content
The purpose of this utility model is to provide a kind of elastic adjustable brush structure, to solve in above-mentioned background technology
The problem of proposition.
To achieve the above object, the utility model provides following technical scheme：A kind of elastic adjustable brush structure, bag
Brush carrier is included, the upper end of the brush carrier is provided with the hollow spiral shell for being interspersed with and coordinating with its screw thread in the middle part of cover plate, the cover plate
Through hole is provided with the middle part of bolt, the hollow bolt, the bottom of the hollow bolt is nested with slot type conducting strip, and the slot type is led
The bottom of electric piece is fixedly connected with shunt welding line, and the end of the shunt welding line is fixedly connected with brush, and shunt welding line is socketed with spring,
One end of the spring is fixedly connected with slot type conducting strip, and the other end of the spring is fixedly connected with brush.
It is preferred that, the upper end of the slot type conducting strip is fixedly connected with extraction wire, and the end of extraction wire is extended
Through hole.
It is preferred that, the end face of the brush is arcuate structure.
Compared with prior art, the beneficial effects of the utility model are：A kind of elastic adjustable brush structure, in
Rotation regulation of the empty bolt in cover plate, the position of slot type conducting strip can be adjusted, so as to the tightness of spring
It is adjusted, so that solve after brush is worn, the problem of elasticity of spring weakens, and caused due to production technology
The problem of spring is not inconsistent standard, can also be solved by adjusting hollow bolt, reduce the difficulty of production technology, be improved
Production efficiency.

Fig. 2 is top view of the present utility model.
In figure：1st, brush carrier, 2, cover plate, 3, hollow bolt, 4, through hole, 5, slot type conducting strip, 6, shunt welding line, 7, brush,
8th, spring, 9, extraction wire.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belongs to the scope of the utility model protection.
Referring to Fig. 1, Fig. 2, the utility model provides a kind of technical scheme：A kind of elastic adjustable brush structure, bag
Brush carrier 1 is included, the upper end of brush carrier 1 is connected with cover plate 2, and the middle part of cover plate 2 is interspersed with the hollow bolt 3 coordinated with its screw thread,
Hollow bolt 3 can be put in and be exited by screwing in cover plate 2, and the shaping of the integral middle of hollow bolt 3 is provided with logical
Hole 4, the bottom of hollow bolt 3 is nested with slot type conducting strip 5, so that hollow bolt 3 and the relative slip of slot type conducting strip 5 are prevented,
Work is more stable, and slot type conducting strip 5 can be moved up and down in brush carrier 1, and the bottom of slot type conducting strip 5 is fixedly connected with brush
Litzendraht wire 6, the end of shunt welding line 6 is fixedly connected with brush 7, so that electric conductivity is more reliable, and shunt welding line 6 is socketed with spring 8,
One end of spring 8 is fixedly connected with slot type conducting strip 5, and the other end of spring 8 is fixedly connected with brush 7.
Specifically, the upper end of slot type conducting strip 5 is fixedly connected with extraction wire 9, and the end of extraction wire 9 is extended
Through hole 4, connects consequently facilitating being communicated with the outside.
Specifically, the end face of brush 7 is arcuate structure, so that good with steering gear contact.
Operation principle：When brush 7 is worn or because production technology causes the bullet of spring 8 by using for a long time
Property is weaker, and during with commutator loose contact, can turn clockwise hollow bolt 3, make in the precession cover plate 2 of hollow bolt 3, then hollow
The bottom extruding slot type conducting strip 5 of bolt 3 is moved down, the extrusion spring 8 of slot type conducting strip 5, so that the elasticity of spring 8 is obtained
Strengthen, brush 7 is recovered good contact with commutator, the brush 7 after abrasion can also continue to use, when due to production technology
When caused spring 8 is elastic excessive, the unit pressure of brush 7 is too high, aggravates the abrasion of brush 7, can be hollow with rotate counterclockwise
Bolt 3, makes hollow bolt 3 screw out cover plate 2, then slot type conducting strip 5 follows hollow bolt 3 to move up, then the elasticity of spring 8 subtracts
It is small, brush 7 is recovered good contact with commutator, so as to reduce to manufacturing technique requirent, improve production efficiency.
While there has been shown and described that embodiment of the present utility model, for the ordinary skill in the art,
It is appreciated that these embodiments can be carried out in the case where not departing from principle of the present utility model and spirit a variety of changes, repaiies
Change, replace and modification, scope of the present utility model is defined by the appended claims and the equivalents thereof.
