The stereoscopic schematic diagram of property component and limit assembly assembling structure different angle；
Fig. 4 is the stereoscopic schematic diagram of 2 assembling structure of the utility model embodiment.
Specific embodiment
The utility model is described in further detail below in conjunction with figure embodiment.
Embodiment 1
As shown in Figure 1 to Figure 3, which includes:
Drawer 1, be used for contain things, be mounted on take out hole in, can according to need select it is in the prior art any one
Structure.
Guide rail 2, setting is in taking out hole, for carrying drawer 1, to facilitate the pull of drawer.
First rack gear 3, is fixed on the side wall of drawer 1, can be mobile relative to guide rail 2 with the pull of drawer 1.
First gear 4 is positioned relative to guide rail 2, and the shaft 41 of first gear 4 is able to rotate ground connecting bracket in the present embodiment
7, bracket 7 is fixed on guide rail 2.First gear 4 can be meshed with the first rack gear 3, and continue to move to the first rack gear 3
It can be detached from and be engaged with first rack gear 3.
Change the stroke that the i.e. changeable drawer of length of the first rack gear 4 is automatically closed.When needing whole-process automatic closing, the
The length of one gear is adapted with the depth for taking out hole.
Elastic parts 5, the elastic parts 5 in the present embodiment include the second gear 52 coaxially connected with shaft 41, and second
Gear engages the second rack gear 53, and the second rack gear 53 can slidably limit on guide block 55, and guide block 55 is fixed on guide rail 2, and second
Elastic component 54 is equipped between rack gear 53 and the frame in drawer hole 11, the elastic component 54 in the present embodiment is spring.
Limit assembly 6 is arranged between drawer 1 and guide rail 2, for preventing the rotation of shaft；Including limit plate 61, limit
Plate 61 is connected on bracket 7, is positioned relative to guide rail 2, and shift fork 62 can be threaded through up or down on limit plate 61, the upper end energy
It contradicts in shaft 41, push plate 63 is directed toward in lower end；Push plate 63 is fixed on drawer 1, can the front and back shifting with the pull of drawer 1
It is dynamic.Push plate 63 includes the planar section 632 that the wedge-shaped segment 631 of the outer end face close to drawer 1 is connected with wedge-shaped segment 631.
In the present embodiment, the upper end of shift fork is arcuate structure compatible with shaft 41, can partially encase shaft 41.
When one end of shift fork 62 contradicts on planar section 632, the other end of shift fork is contradicted in shaft 41；When shift fork 62
One end when being detached from planar section, the other end of shift fork is detached from the conflict to shaft 41；At this point, shaft can be in first gear or second
It is rotated under the drive of gear.
When opening drawer, the first rack gear is moved forward with the movement of drawer, when touching first gear 4, the two engagement,
The mobile driving first gear of first rack gear rotates, and drives the rotation of second gear original place, second gear driving second by shaft
Rack gear travels forward, and squeezes spring.
With the Forward of drawer, the lower end of shift fork touches wedge-shaped segment, then slides into planar section, fork is in planar section
It is moved up under conflict, contradicts its upper section in shaft, by shaft locking；And at this point, spring is extruded into maximum distortion.In shift fork
Under the action of, shaft is motionless, and second gear is motionless, and the second rack gear will not move backward under the engagement of second gear.
When needing to close drawer, drawer is pushed backward manually, push plate is moved backward with drawer, when moving to shift fork
Lower end when being directed toward wedge-shaped segment, the upper end of shift fork is detached from the conflict to shaft, at this point, under the action of recoil of spring power, spring
The second rack gear is driven to move backward relative to guide block, the rotation of driving second gear original place drives first gear rotation by shaft,
First gear pushes the first rack gear being engaged with to move back, to close drawer.
With the release of spring kinetic energy, elastic potential energy gradually weakens, therefore closure first quick and back slow is presented in drawer
Speed, drawer are finally slowly closed, will not take out hole frame between occur quickly collision, close drawer movement and it is soft.
Embodiment 2
As shown in figure 4, the elastic parts in the present embodiment is wind spring 51, the inner end of wind spring 51 is fixedly connected with shaft 41, outside
End is fixed on bracket 7.
Wind spring 51 is with the rotation of first gear, and under the action of shaft, wind spring turns round volume accumulation of energy.
When closing drawer, after shift fork is detached from the conflict of planar section, wind spring reversion relaxation drives shaft rotation, to make the
One gear drives the Forward of the first rack gear.
Remaining content is same as Example 1.
