And realize and air quantity is accurately in time adjusted, meet actual operation requirements.
To solve the above problems, the technical solution used in the present invention is as follows：
A kind of throttle setting of rack pinion control, is mainly made up of, institute fixed plate, fan housing, air door, motor, gear and rack
State and air vent is machined with fixed plate, the fan housing and air door are arranged in fixed plate, and the fan housing and the air door are in fixation
The cover space of a sealing is formed on plate and the cladding air vent is set, the motor is arranged on fan housing；
To open completely, the fan housing four additional side and upper surface are set for the side of the air vent of the fan housing opposing fixed plate
It is equipped with fixed ventilating opening and at least one movable ventila mouth；
The guiding for fixing the pore structure of motor and being used cooperatively is additionally provided with the fan housing, electricity is provided with the motor
Arbor, the gear are installed on the motor shaft, and teeth and elongated slot that mate gear uses are provided with the rack；
The protruding shaft structure and several hole axle structures for coordinating elongated slot to use are additionally provided with the fan housing, is provided with the air door
For air door to be assembled into the axial aperture structure that at movable ventila mouth and mating holes axle construction uses.
As the improvement of above-mentioned technical proposal, fixing hole is provided with the fixed plate and the fan housing, and fan housing is
It is fixed on by being used cooperatively for fixing hole in fixed plate.
It is described to be oriented to the outside or inner side for being provided in fan housing as the improvement of above-mentioned technical proposal.
Compared with prior art, implementation result of the invention is as follows by the present invention：
A kind of throttle setting of rack pinion control of the present invention, on the premise of meeting just to manipulate, is realized to refrigerator
And the air door of refrigerator-freezer and each region be in control of the different time sections to cold blast rate, and realize and air quantity accurately in time adjusted,
Meet actual operation requirements.

Embodiment
Illustrate present disclosure below in conjunction with specific embodiments.
As shown in Figures 1 to 7, it is the throttle setting structural representation of rack pinion of the present invention control.
Embodiment
The present invention is made up of fixed plate 1, fan housing 2, air door 3, motor 4, gear 5, rack 6.
Fixed plate 1：In definite shape（It is including but not limited to square）The corresponding position in air channel is fixed on, there is air vent 10
Circulated for cold air, air vent 10 has corresponding ventilation-sectional area so that meets the requirement of certain ventilation, fixed plate
1 also has fixing hole 21, and for fixing fan housing 2, fixing hole 21 is arranged in fixed plate 1 with quantity in a desired fashion；
Fan housing 2：In definite shape（It is including but not limited to square）, it may have some fixing holes 21, using screw or other fastenings
Part is fixed in fixed plate 1, forms the space of a cover shape, and fan housing 2 is to beat completely except the side of air vent 10 of opposing fixed plate 1
Outside opening, the either side or more sides of four sides and upside arrange fixed ventilating opening 22 or movable ventila mouth 23 and at least on demand in addition
Side is movable ventila mouth 23；
Wherein, also there are several hole axle structures 24, for air door 3 to be assembled at movable ventila mouth 23 so that wind on fan housing 2
