Helical gear, shaft, connector and sliding rack partial structurtes decomposition diagram.As shown in Figure 1 to Figure 3, the utility model
The drawer appliance of embodiment includes 20, two helical gears 300 of drawer, shaft 600 and two helical racks 121.
Drawer 20 can be arranged in refrigeration compartment 101 to front and back push-and-pull.Typically, for being provided with refrigerating chamber, freezing
Room, and be further provided with for the refrigerating device (such as refrigerator of large capacity) of temperature-changing chamber, drawer 20 is generally arranged
In freezing chamber, temperature-changing chamber.
Drawer 20 is usually upside open container, and drawer 20 can be pulled out refrigeration compartment 101 by user, to access object
Product.The utility model embodiment can be used following two forms and use drawer.First, being provided on front side of refrigeration compartment independent
Door body after user first need to open door body, could pull out drawer.Second, on front side of refrigeration compartment and door body is not provided with, in drawer quilt
When being pushed into refrigeration compartment, the front panel of drawer is closed outside the front openings and the front of composition refrigerating device of refrigeration compartment
It sees, such as common " drawer door " structure in French refrigerator.
Two helical gears 300 can be rotatably mounted at lateral the two of drawer 20 along lateral (i.e. left and right directions) axis respectively
End.Shaft 600 extends in transverse direction and axial both ends 610 are individually fixed in two helical gears 300, so that two helical gears
300 rotation synchronizes.Two helical racks 121 extend and are directly or indirectly fixed on refrigeration compartment 101 along the longitudinal direction respectively
Both lateral sides wall.When drawer 20 is by front and back push-and-pull, make the synchronous rolling on two helical racks 121 respectively of two helical gears 300
It is dynamic, to enable the transverse ends synchronizing moving of drawer 20, drawer 20 is enable smoothly to be pulled out, be pushed by smooth, is promoted
User experience.
Specifically, as shown in Fig. 2, each drawer appliance further includes two sliding rails 100 and two sliding racks 200.Wherein,
Two sliding rails 100 are individually fixed in the both lateral sides wall of refrigeration compartment 101 and extend along the longitudinal direction.Two sliding racks 200 divide
The transverse ends for not being installed on drawer 20 extend along the longitudinal direction.Each sliding rack 200 is arranged in a cunning in which can slide back and forth
On rail 100, to allow the front and back push-and-pull of drawer 20.Two helical gears 300 are separately mounted on two sliding racks 200.
As shown in Fig. 2, each sliding rail 100 includes vertically extending to be posted by the vertical of the lateral sidewalls of refrigeration compartment 101
Plate 110 and from 110 lower end of vertical plate to the horizontal-extending level board of 101 another lateral sidewalls of refrigeration compartment 120.Level board 120
The side upper surface of separate vertical plate 110 form helical rack 121 above-mentioned, sliding rack 200 is located at vertical plate 110 and helical rack
Between 121.
Further, fixed there are one connector 510 on each sliding rack 200 such as Fig. 3, on connector 510 there are one tools
The circular pivot end 500 being laterally extended, opens up that there are one round holes 310 to allow circular pivot end on each helical gear 300
Portion 500 stretches into wherein, and previously described helical gear 300 connector 510 is rotatably installed on to realize.Shaft 600
The circumferential surface at axial both ends 610 be non-circular structure (such as two sides be cambered surface, two sides be plane-parallel quadrilateral structure), two
Non-circular axis hole (not shown) is offered on a helical gear 300, to be inserted into the axial both ends of shaft 600, non-circular shaft respectively
The cooperation at hole and non-circular axial both ends 610 make shaft 600 and helical gear 300 can not relative rotation, ensure that two
The synchronous rotation of helical gear 300.
In some alternative embodiments, spur gear and spur rack can also be used and replace helical gear 300 above-mentioned and tiltedly
Rack 121.But the inventor of the utility model recognizes through test of many times, using the effect of helical gear 300 and helical rack 121
Fruit is more preferably.Specifically, when helical gear 300 is driven, tooth, which is fade-in, gradually to be gone out, and registration is bigger than spur gear, keeps transmission more steady.
Moreover, helical gear 300 can carry certain axial force, further avoids the double swerve of drawer 20 or even be dislocated.
In addition, registration is big between helical gear 300 and the tooth of helical rack 121, contact stress reduces so that its noise is smaller and carries energy
Power is stronger, longer life expectancy, avoids user for a long time using after drawer, needs to change the trouble of gear, rack.
Although those skilled in the art will appreciate that the detailed multiple exemplary implementations for showing the utility model herein
Example, still, still can be direct according to content disclosed by the utility model in the case where not departing from the spirit and scope of the utility model
Determine or derive many other variations or modifications for meeting the utility model principle.Therefore, the scope of the utility model should be by
Understand and regards as covering other all these variations or modifications.
