Description
Technical field
The utility model is related to Sample preservation technical field, specifically, is a kind of low temperature refrigerator tray both slid mechanism.
Background technology
In available sample collection Techniques of preserving, it is often necessary to low temperature, deep-bed drying.It is general that Sample preservation is low to depth
In temperature refrigerator, in order to improve storage capacity, multiple layer tray is set in refrigerator, a cunning is respectively provided with each pallet left and right sides
Rail, each pallet individually can be pulled out and be pushed into along slide rail.
But, existing refrigerator, using existing pallet slide rail, all suffers from following ask under low temperature and profound hypothermia environment
Topic：
Slide rail is easily freezed to death, and pulls out push-in difficult.
Current profound hypothermia refrigerator, all without automatic defrosting system, in the refrigerator inside of refrigeration, pallet, slide rail etc. are exposed
Surface all can frosting, to be put into or taking out sample box, it is necessary to pull out pallet, pallet is contacted with indoor high temperature air, pallet and cunning
The frost of track surface can be melted into water, and after pallet is pushed into refrigerator again, the water that slide rail surfaces externally and internally has melted can freeze；
In addition, the water manually melted on the pallet and slide rail after defrosting, can also freeze when being freezed again, so result in generally
The more piece ball guide used is frozen in and stiff so that pallet can not be pulled out, and cooling time is longer, can not more be drawn
Go out.
In addition, commercially available slide rail can't adapt to the size change that refrigerator inside and pallet are produced due to excessive temperature difference
Change, slide rail is easily damaged, and poor reliability, service life is short.
Utility model content
In order to solve the above problems, the utility model proposes a kind of low temperature refrigerator tray both slid mechanism, in profound hypothermia state
Under be both difficult frosting and freezed to death, the change of refrigerator and pallet dimension caused by the larger temperature difference is can adapt to again.
To reach above-mentioned purpose, the concrete technical scheme that the utility model is used is as follows：
A kind of low temperature refrigerator tray both slid mechanism, including the fixed rack bar of cabinet wall is fixed on, and it is fixed on support
Pan Cebi slider bar, its key is：The fixed rack bar is mutually chimeric with the slider bar, the slider bar with it is described solid
Determine slide rail bar linear contact lay or face contact, the fixed rack bar supports the slider bar, the cunning through contact line or contact surface
Dynamic bar is slided along the fixed rack bar；
Or the fixed rack bar is provided with fixed strip and lower fixed strip, the slider bar stretches into fixed strip with
Between fixed strip, and slider bar only has the top contact of bottom and the lower fixed strip；
Or the slider bar is provided with slip band and lower slider band, the fixed rack bar stretches into slip band with
Between slip band, and slider bar only has the bottom of upper slip band and the top contact of the fixed rack bar.
By above-mentioned design, fixed rack bar and slider bar linear contact lay or face contact, first, can be with when pulling pallet
Reduce the frictional resistance between fixed rack bar and slider bar.Second, available in profound hypothermia refrigerator, being difficult to be freezed to death to block,
Even if being frozen in, because contact area is small, when pulling pallet, using less power pallet can be made smoothly to pull out.Gu and
Determine slide rail bar and slider bar line nested mode can stochastic transformation, it is adaptable to adapt to different working environments.Slider bar is only
Contacted with a face of fixed rack bar, can the defect that is frozen in of effectively anti-anti-slip track, improve what profound hypothermia refrigerator was used
Reliability.

Fixed strip, slider bar are integrally formed.
First raised line and upper fixed strip and slider bar are integrally formed；Second raised line and upper fixed strip, slider bar are integrally formed；
When pulling pallet, integrally formed structure makes the gap uniformity of fixed strip and slider bar therebetween, mutually slides more
Reliably, frictional resistance is small, and uncomfortable gap easy to assembly, cost is low.
Fixed bar, lower fixed strip or/and the slider bar are in cylinder or elliptical cylinder-shape.
Cylinder or elliptical cylinder-shape, connecing in reduction between fixed strip and slider bar, between lower fixed strip and slider bar
Contacting surface is accumulated, and then reduces frictional resistance.
On described the 3rd raised line, the lower slider band are provided with the top of slip band bottom or/and the fixed rack article
Top or/and the fixed rack article bottom are provided with the 4th raised line, and the 3rd raised line, the edge of the 4th raised line are in circular arc
Face shape or planar shaped are linear.
When being provided with three raised lines at the top of the slip band bottom on described and the fixed rack article, this two the 3rd convex
Bar is staggered.At the top of the same lower slider band and when the fixed rack article bottom is provided with four raised lines, this two
4th raised line is staggered.Be staggered the change that may be such that slide rail can adapt to refrigerator and pallet dimension caused by the larger temperature difference
Change.
3rd raised line and the upper slip band or/and the fixed rack article are integrally formed；4th raised line with
The lower slider band or/and the fixed rack bar are integrally formed.
Using such scheme, frictional resistance is small, applies to profound hypothermia environment, sliding track mechanism is difficult to be freezed to death, using reliable
Property it is high.
The beneficial effects of the utility model：The present apparatus is the slide construction for being adapted to profound hypothermia environment, uses " C " shape gear frost
Cover gear frost, reduces the contact area of fixed rack bar and slider bar, reduces the frictional resistance between the two, efficiently solves deep low
The problem of warm slide construction is easily freezed to death.Meanwhile, the structure coordinated using raised line and plane so that slide rail can adapt to larger
The change of refrigerator and pallet dimension caused by the temperature difference.
