Abstract
The utility model relates to a small-size household appliance, in particular to a firm carbon brush difficult to fall off. The firm carbon brush comprises a carbon brush body, a wire led out of a fixing hole of the carbon brush body, and a copper sheet fixed at the other end of the wire, wherein the wire is fixed on the carbon brush body and the copper sheet through bolts. By the firm carbon brush, a large vibration force produced during rotation of the appliance is prevented, so that the wire hardly falls off. The wire, the copper sheet and the carbon brush body are fixedly connected through the bolts; compared with welding, fixed connection has the advantages that the firm carbon brush is easy to maintain; equipment does not need to be replaced; the firm carbon brush is firmer and is simple in structure; and the service life of the carbon brush is prolonged.
Description
Technical field
The utility model relates to a kind of small household appliances product, particularly relates to a kind of carbon brush of firm difficult drop-off.
Background technology
Carbon brush is the device of transferring energy or signal between the standing part of motor or generator or other rotating machineries and the rotating part, and it generally is that pure carbon adds coagulating agent and makes, and external form generally is square, is stuck on the metallic support.Some carbon brush structure is simple, and wire is pressed by the copper sheet chieftain, because mechanical rotation produces larger shaking force, comes off easily, and shorten the useful life of carbon brush.If carbon brush body and copper sheet are welded, then since connect too firm, in case come off exchange device again just, cost height.
The utility model content
The technical problems to be solved in the utility model provides a kind of carbon brush of firm difficult drop-off of simple in structure, long service life.
Content of the present utility model is that it comprises the copper sheet that carbon brush body, the wire of deriving and the wire other end are fixing from the fixing hole of carbon brush body, and described wire is bolted on carbon brush body and the copper sheet.
Described carbon brush body be shaped as square.
The number of described wire is 2.
The beneficial effects of the utility model are, the utility model has overcome the larger shaking force that produces in the electrical equipment rotation process, the wire difficult drop-off, the utility model is bolted to connection wire and copper sheet and carbon brush body, compares welding, keeps in repair easy, do not need more exchange device, while is more firm, simple in structure, has increased the useful life of carbon brush.
Description of drawings
Accompanying drawing is structural representation of the present utility model.
In the drawings, 1 carbon brush body, 2 fixing holes, 3 bolts, 4 wires, 5 copper sheets.
Embodiment
As shown in drawings, wire 4 and the fixing copper sheet 5 of wire 4 other ends that the utility model comprises carbon brush body 1, derives from the fixing hole 2 of carbon brush body 1, described wire 4 is fixed on carbon brush body 1 and the copper sheet by bolt 3.
Described carbon brush body 1 be shaped as square.
The number of described wire 4 is 2.
The utility model has overcome the larger shaking force that produces in the electrical equipment rotation process, wire 4 difficult drop-offs, the utility model is fixedly connected with wire 4 and copper sheet 5 and carbon brush body 1 by bolt 3, compare welding, keep in repair easyly, do not need more exchange device, simultaneously more firm, simple in structure, increased useful life of carbon brush.
