The invention discloses a kind of screen slidings used for range hood to open and close transmission mechanism, including screen sliding, movable floor, guide rail, transmission system, motor group, panel, cabinet, air inlet.The screen sliding is fixedly arranged on movable floor, guide rail is installed between movable floor and panel, the transmission system and motor group are fixed on panel, the transmission system includes gear, rack gear, rack and pinion intermeshing, the rack gear side are equipped with guiding mechanism, and gear and guiding mechanism are respectively placed in rack gear two sides, the guiding mechanism includes rotatable rolling element, abuts rack gear.Compared with prior art, the beneficial effects of the present invention are: by motor-driven gear, rack and pinion engagement transmission, rack drives movable floor is slided up and down, and then realizes the folding up and down of screen sliding.Compared to common individual gears rack-driving, guiding mechanism is increased, enhances the stationarity of transmission, ensures that beat will not occur for rack pinion hour rack.
Description
Technical field
The present invention relates to a kind of range hood screen slidings to open and close transmission mechanism.
Background technique
As the pursuit of quality of the life is continuously improved in people, the range hood applied to kitchen is increasingly becoming indispensable
Living electric apparatus, and with excellent quality, exquisite appearance, easy to clean also become pay close attention to item when people buy range hood
Mesh.
Traditional side extraction cooking fume extractor, air inlet is mostly directly exposed in air, not beautiful enough, meanwhile, flue
In remaining oil smoke can be diffused into interior, pollute air.Currently, there is the range hood of some automatic open-close panels, but
Simple individual gears rack-driving structure is mostly used greatly, and stability is poor, easily shakes.
Summary of the invention
The technical problem to be solved by the present invention is to the one kind proposed for above-mentioned state of the art is used for range hood
Screen sliding opens and closes transmission mechanism, and transmission stability is more preferable, is not easy to shake.
The technical scheme of the invention to solve the technical problem is: a kind of range hood screen sliding opens and closes driver
Structure, including screen sliding, movable floor, guide rail, transmission system, motor group, panel, cabinet, air inlet, the screen sliding are fixedly arranged on activity
On bottom plate, guide rail is installed between movable floor and panel, the transmission system and motor group are fixed on panel, the biography
Dynamic system includes gear, rack gear, rack and pinion intermeshing, it is characterised in that and the rack gear side is equipped with guiding mechanism,
Gear and guiding mechanism are respectively placed in rack gear two sides, and the guiding mechanism abuts rack gear.
Further, at least three, the guide rail, including left rail, middle guide rail, right guide rail, the rack gear are installed on work
Between dynamic bottom plate and middle guide rail, and guide rail and rack gear are installed using fixture, are directly play the guiding role to the movement of rack gear, guarantee tooth
Item movement is more stable.
Further, the guiding mechanism includes two rotatable rolling elements, and the rolling element was symmetrically distributed in tooth
The vertical line two sides of the center of circle and the vertical tooth rack direction of motion are taken turns, rack gear during the motion then will not be uneven because of the lateral force being subject to
It weighs and beat occurs.
Further, the rolling element of the guiding mechanism must be against rack gear and when bearing rack pinion perpendicular to tooth
The cross component force of the direction of motion, rolling element are fixed on pedestal, and pedestal is screwed on panel, between screw and pedestal
Equipped with taperliner, have on pedestal and the matched inclined-plane of taperliner.The coupling mechanism force of screw separates horizontal direction by inclined-plane
Component ensures that the guiding mechanism moment is close to rack gear, limits rack gear beat.
Compared with prior art, the beneficial effect of present example is: passing through motor-driven gear, rack and pinion engagement
Transmission, rack drives movable floor move up and down, and then realize the folding up and down of screen sliding.It is passed compared to common individual gears rack gear
It is dynamic, guiding mechanism is increased, the stationarity of transmission is enhanced, ensures that beat will not occur for gear, rack-driving hour rack.
Detailed description of the invention
Fig. 1 is overall structure diagram of the invention；
Fig. 2 is the positive structure schematic of transmission system and guiding mechanism of the invention；
Fig. 3 is the cross section structure schematic diagram of transmission system and guiding mechanism of the invention.
Specific embodiment
The present invention will be described in further detail below with reference to the embodiments of the drawings.
Referring to figs. 1 to Fig. 3, a kind of range hood screen sliding opens and closes transmission mechanism, including screen sliding 1, movable floor 2, guide rail 3,
Transmission system 4, motor group 5, cabinet 6, panel 7, air inlet 8, the screen sliding 1 are fixedly arranged on movable floor 2, movable floor 2
Guide rail 3 is installed between panel 7, the transmission system 4 and motor group 5 are fixed on panel 7, and the transmission system 4 includes
Gear 41, rack gear 42, rack gear 42 and gear 41 are intermeshed, it is characterised in that: 42 side of rack gear is equipped with guiding mechanism
9, gear 41 and guiding mechanism 9 are respectively placed in 42 two sides of rack gear, and the guiding mechanism 9 includes rotatable rolling element 91, and tight
By rack gear 42.
The air inlet 8 is under movable floor 2, when movable floor 2 is opened, drives sliding in screen sliding 1, exposing air inlet 8.
At least three, the guide rail 3, including left rail 31, middle guide rail 32, right guide rail 33, rack gear 42 be installed on dump bottom
Between plate 2 and middle guide rail 32, left rail 31 and right guide rail 33 are distributed in the two sides of movable floor 2, and movable floor 2 slides up and down
When, it is flexible that several guide rails follow movable floor 2 simultaneously, while playing guiding.
The guiding mechanism 9 contains at least two the above rotatable rolling element 91, for example rolling bearing can be selected etc., rolling
Kinetic force of friction is small, will not wearing part and influence transmission.And rolling bearing is preferably along the rack movement direction for crossing the gear center of circle
Vertical line two sides are symmetrical, and then because the lateral force being subject to is uneven beat will not occur for rack gear during the motion.
Perpendicular to rack movement side when the guiding mechanism 9 must be close to rack gear 42 and bear gear 41, rack gear 42 is driven
To cross component force, therefore 92 bearing of pedestal of guiding mechanism 9 can be processed as inclined-plane, and additional lock washer 93 is locked, and screw is made
Coupling mechanism force separates the component of horizontal direction by inclined-plane, ensures that 9 moment of guiding mechanism is close to rack gear 42, limits 42 beat of rack gear.
