Specific embodiment
In the following with reference to the drawings and specific embodiments, the utility model is furtherd elucidate.These embodiments are merely to illustrate this
Utility model rather than limitation the scope of the utility model.
A kind of refrigerator air door of band signal feedback, as shown in Fig. 1, including gear-box 1, DC stepper motor 2, gear subtract
Speed system 3, door-plate 4, swing rod 5, spring 6, microswitch 7, bracket 8, printed circuit board 9, DC stepper motor 2, The gear deceleration
System 3, swing rod 5, spring 6, microswitch 7, bracket 8, printed circuit board 9 are mounted in gear-box 1, and door-plate 4 is outside gear-box 1
And it is mounted on door frame 41.The chopped-off head gear 31 and DC stepper motor 2 of gear reduction system 3 are sequentially connected, gear reduction train
The final-stage gear 37 and door-plate 4 of system 3 are sequentially connected, and DC stepper motor passes through The gear deceleration according to pulse signal reciprocating rotary
System drives door-plate sweeping action, realizes and opens the door and close the door.
In conjunction with shown in attached drawing 2, on the end face of a certain reduction gearing 32 in gear reduction system 3 in addition to chopped-off head gear 31
Equipped with cam 33, cam 33 forms cam structure to open up deep gouge on 32 end face of reduction gearing, the arc projecting surface of cam
36 two endpoints are stop end point 34,35, and the shutdown point and standard-sized sheet doors corresponding to door-plate is respectively associated.Reduction gearing 32 is excellent
The penultimate stage gear or final-stage gear 37 for first selecting gear reduction system, because of each gear in combination gear deceleration system
The relationships such as transmission ratio, penultimate stage gear and final-stage gear can be associated within the circle of own rotation one and correspond to door-plate
Shutdown point and standard-sized sheet doors.
In conjunction with shown in attached drawing 3, swing rod 5 includes swinging axle 51, arm of force A52, arm of force B53 positioned at 51 two sides of swinging axle.Tooth
There are two brackets 8, swinging axle 51 to be erected on bracket 8 for setting in roller box 1, and using swinging axle as fulcrum, swing rod carrys out back rotation.It swings
Axis, arm of force A, arm of force B can be the fixed overall structure of three, and swinging axle is erected on bracket by bearing, and entire swing rod is logical
Swinging axle is crossed to rotate back and forth；Being also possible to arm of force A, arm of force B is the fixed overall structure of the two, and swinging axle is arranged in wherein, wears
If bearing is arranged in position, swinging axle is erected on bracket and fixes, and arm of force A and arm of force B entirety carry out back rotation around it on swinging axle.
The projecting surface 36 of cam 33 is opposite with arm of force A52, and the top guide 54 erect towards cam 33 is provided on arm of force A52,
The inner wall of top guide 54 and cam 33 is sequentially connected, the compression of spring 6 be connected to arm of force A52 and gear-box 1 (bottom or case lid) it
Between, microswitch 7 as shown in Fig. 4 is mounted on gear-box 1 by its stabilizer blade 71, and button 72 is opposite with arm of force B53.It is micro-
