Description
Technical field
The utility model relates to the switching technique field, relates in particular to a kind of knob switch of being convenient to shift gears that is used for food cooking machine.
Background technology
Like product generally is to control the transition of each gear through hacking copper sheet in the market, and this kind mode major defect is that the transition of each gear is clear inadequately, and feel is poor, and cost is high, causes the copper sheet loose contact in user's use and product can not be used.
The utility model content
The purpose of the utility model provides a kind of rotary switch of being convenient to shift gears, and has overcome the above-mentioned deficiency of prior art, and the conversion of each gear of switch can clear transition, good hand touch, and cost is low, prolongs the useful life of product.
In order to reach above-mentioned purpose of design, the technical scheme that the utility model adopts is following:
A kind of rotary switch of being convenient to shift gears; Comprise switchboard, switch copper sheet, switchboard axle, contact, fix the switch copper sheet in the said switchboard axle that is coupling on switchboard, switch copper sheet front end is provided with a plurality of contacts that are uniformly distributed with; Said switchboard axle side is provided with tooth-shape structure; Be provided with switch transition fulcrum relatively with tooth-shape structure on the switchboard, switch transition button point piston mode is fixed in the pedestal on the switchboard, is provided with switch transition button point spring between switch transition button point bottom and the pedestal; Pedestal is extended on switch transition button point top, and meshing with the tooth-shape structure of switchboard axle side.
When the tooth-shape structure of said switch transition fulcrum and switchboard axle was meshing one by one, switch copper sheet front end contacted with contact one by one.
Connect silicon rectifier diode between said adjacent two contacts.
Said switch copper sheet rear end is provided with some movable contact springs, and when the switch copper sheet was in 0 gear, its rear end was relative with the some movable contact spring.
Said some movable contact spring is connected to the contact that contacts when the switch copper sheet is in high tap position through lead-in wire.
Pass through rivet locking switchboard on the said switchboard.
The beneficial effect of the described rotary switch of being convenient to shift gears of the utility model is: adopt simple switch transition button point to replace the copper sheet transition; Thereby make product can not make the loose contact situation that the life-span is prolonged, and reduced the cost of product because of the modification of being heated of switch copper sheet; Easy to loading and unloading, and do not influence function; Rational in infrastructure; Practical.
Description of drawings
Fig. 1 is the sketch map of the described rotary switch of being convenient to shift gears of the utility model embodiment.
Fig. 2 is the exploded view of the described rotary switch of being convenient to shift gears of the utility model embodiment.
Embodiment
Below in conjunction with accompanying drawing the optimum implementation of the utility model is done further detailed description.
As illustrated in fig. 1 and 2; A kind of rotary switch of being convenient to shift gears comprises switchboard 1, lug plate 2, switch copper sheet 3, switchboard axle 4, contact 6, switch transition button point 7, switch transition button point spring 8, silicon rectifier diode 9, some movable contact spring 11, switch cover 12, the said switchboard 1 one middle side parts switchboard axle 4 that is coupling; Fix switch copper sheet 3 in the groove position of switchboard axle 4; Switch copper sheet 3 contacts with lug plate 2, and lug plate 2 is connected to an electric current line, and another electric current line connects double-speed motor; Said switchboard axle 4 sides are provided with tooth-shape structure; Be provided with switch transition fulcrum 7 relatively with tooth-shape structure on the switchboard 1, switch transition button put 7 piston modes be fixed on the switchboard 1 in the pedestal, switch transition button is put and is provided with switch transition button point spring 8 between 7 bottoms and the pedestal; Switch transition button is put 7 tops and is extended pedestal, and meshing with the tooth-shape structure of switchboard axle 4 sides; Said switch copper sheet 3 front ends are provided with the contact 6 of fixing in a plurality of even layouts at switchboard 1 edge relatively; Said switch copper sheet 3 front ends contact with contact 6, conducting; Connect silicon rectifier diode 9 between adjacent two contacts 6, said switch copper sheet 3 rear ends are provided with some movable contact springs 11, when switch copper sheet 3 is in 0 gear; Its rear end is relative with some movable contact spring 11, and said some movable contact spring 11 10 is connected to the contact 6 that contacts when switch copper sheet 3 is in high tap position through going between; Pass through rivet 5 locking switchboards 12 on the said switchboard 1.
When the tooth-shape structure of said switch transition fulcrum 7 and switchboard axle 4 was meshing one by one, switch copper sheet 3 front ends contacted with contact 6 one by one.
When 4 rotations of switchboard axle, drive switch copper sheet 3 and contact with contact 6, thus the conducting motor rotation, motor speed was different when switch copper sheet 3 contacted with different contacts 6; The flute profile that distributes on switch transition button point 7 and the switchboard axle 4 is meshing; Compression switch transition button point spring 8 during 4 rotations of switchboard axle; When switchboard axle 4 rotates to next flute profile; Switch transition button point 7 is return under the elastic force of switch transition button point spring 8, makes the enclosure wall percussion on switch transition button point 7 and the switchboard 1, thereby produces the sound of gear transition clearly; Going between 10 1 terminates at above the contact 6 of high tap position, and an end is connected above the movable contact spring 11, puts when pressing switch copper sheet 3 bottom positions at 0 gear when switch, switch copper sheet 3 contact, from face realization crawl function with some movable contact spring 11.
The preferred embodiment of this embodiment the utility model can not limit the utility model, and concrete each item rights protection scope is defined by the claims.
