Abstract
The utility model discloses an improved carbon brush used for small appliances. The carbon brush comprises a carbon brush body, wherein the carbon brush body is internally provided with a fixed block, a wire is wound on the fixed block, and one end, stretching out from the carbon brush body, of the wire is welded together with a copper sheet; and a groove is formed on the copper sheet, the copper sheet is also provided with a round hole, a spring is sleeved at the periphery of the wire, one end of the spring is welded on the carbon brush body, and the other end of the spring is welded on the copper sheet. The improved carbon brush provided by the utility model has the advantages that one end of the wire is wound on the fixed block in the carbon brush body and has less possibility of falling off; the other end of the wire is welded in a round groove on the copper sheet, and the interior of the round groove is subjected to overlaying welding, so that the weld is firm, and the other end of the wire has less possibility of falling off; and the carbon brush does not need to be repeatedly replaced, so that time is saved and the cost is saved.
Description
Technical field
The utility model relates to carbon brush, relates in particular to a kind of improved small household appliances and uses carbon brush.
Background technology
Carbon brush is the device that transmits energy or signal between standing part and the rotating part of motor or generator or other rotating machineries, and it generally is that pure carbon adds coagulating agent and processes, and external form generally is a square, is stuck on the metallic support.Because mechanical rotation produces bigger shaking force, the part that comes off easily is between lead and the carbon brush body, and also having one is between lead and the copper sheet; No matter which part comes off, and machinery then no longer rotates, and must change carbon brush again; The cost that the not only delay time at stop, and carbon brush uses increases greatly.Therefore, need provide a kind of new technical scheme to solve the problems referred to above.
The utility model content
The purpose of the utility model provides the improved small household appliances of a kind of difficult drop-off, long service life and uses carbon brush.
The technical scheme that the utility model adopts is:
A kind of improved small household appliances are used carbon brush, comprise the carbon brush body, are provided with fixed block in the said carbon brush body; Be wound with lead on the said fixed block, said lead stretches out this external end of carbon brush and copper sheet welding, is formed with groove on the said copper sheet; Also have circular hole on the said copper sheet; Said lead periphery is with spring, and said spring one end is welded on the carbon brush body, and the said spring other end is welded on the copper sheet.
Said lead stretches out this external end of carbon brush and is welded in the groove on the copper sheet.
Said groove shapes is circular.
The beneficial effect of the utility model: lead one end is wound on the intrinsic fixed block of carbon brush, and difficult drop-off, the lead other end are welded in the circular groove on the copper sheet; Built-up welding easily in the circular groove makes firm welding, difficult drop-off; Need not to repeat to change carbon brush, save time and practice thrift cost.
