Fig. 2 is the use state diagram (non-direct contact state) of this utility model one embodiment.
Fig. 3 is the use state diagram (direct contact condition) of this utility model one embodiment.
Detailed description of the invention
Combine accompanying drawing below by specific embodiment this utility model is described in further detail.
Referring to Fig. 1, shown in figure is a kind of biological sample storage bin.Its structure mainly by case body 1, cover plate 2,
The parts compositions such as storage element 3, elastic block piece 4, liquid nitrogen supplementary units 5, LED display 6 and liquid nitrogen 7.
Described case body 1 has body top surface 10, body bottom surface and connects described body top surface 10 and described body bottom surface
This body side surface.Described body top surface 10 is vertically oppositely arranged with described body bottom surface system.Have on described body top surface 10 to
The accommodating chute 101 that direction, described body bottom surface depression is arranged.Described accommodating chute 101 has the chute opening set up.
The quantity of described accommodating chute 101 can be one and more than.In this enforcement, it is seen from figure 1 that, described accommodating chute 101
Quantity has five, is uniformly distributed.
Described cover plate 2 is pivotably incorporated on described body top surface 10 by pivot.Described cover plate 2 is right
Body top surface 10 described in Ying Yu.When described cover plate 2 offsets with described body top surface 10, described cover plate 2 can seal described
Chute opening so that described cover plate 2 and described accommodating chute 101 can jointly define and store for described storage element 3
Airtight accommodation space.
Described liquid nitrogen 7 is conventional coolant.Described liquid nitrogen 7 is placed in the bottom of described accommodating chute 101.Described liquid nitrogen
7 have liquid nitrogen liquid level 70(as shown in Figure 2).There is between described liquid nitrogen liquid level 70 and described body top surface 10 first vertical distance.
It should be noted that the vertically distance of first here measures in a state of fig. 2.
Described storage element 3 has unit end face, unit bottom surface 30 and connects described unit end face and described unit bottom surface
The unit side of 30.Described unit end face is vertically to be oppositely arranged with described unit bottom surface 30.Described storage element 3 is corresponding to institute
State accommodating chute 101.In the present embodiment, described accommodating chute 101 and described storage element 3 are all rectangular configuration, described storage
A unit 3 little size more overall than described accommodating chute 101, slips into facilitate.On described unit side, there is surface groove 31.
Described surface groove 31 is from vertically extending to described elastic block piece 4 position, position, described unit bottom surface 30.Described surface is recessed
The quantity of groove 31 can be more than one.In the present embodiment, it is seen from figure 1 that, the quantity of described surface groove 31 has 8, all
Even distribution.The purpose of design of described surface groove 31 is the contact area increasing described storage element 3 with described liquid nitrogen 7, it is ensured that
The sample being stored is fully contacted with described liquid nitrogen 7.Needing instruction sheet is that contact area and contact here all include directly connecing
The state (described storage element 3 is dipped in described liquid nitrogen 7) touched, also includes that (described storage element 3 is in institute for the state of mediate contact
State the top of liquid nitrogen 7).
Described elastic block piece 4 is incorporated on described unit side.Described elastic block piece 4 has horizontal brace open state and vertically
Collapsed state.There is between described elastic block piece 4 and described unit bottom surface 30 second vertical distance.Described second vertical distance is little
In the described first vertical distance.
Described liquid nitrogen supplementary units 5 is incorporated into described body side surface.Described liquid nitrogen supplementary units 5 is in order to supplement described liquid nitrogen
The capacity of 7, it is ensured that long-term cooling and storage temperature.
The temperature ginseng of the described LED display 6 capacity parameter and/or described accommodating chute 101 in order to show described liquid nitrogen 7
Number.
Use process: described storage element 3 slips in described accommodating chute 101 from described chute opening.In described storage
During unit 3 slips in described accommodating chute 101, when described elastic block piece 4 level struts, described elastic block piece 4 can be with
Described body top surface 10 offsets so that described storage element 3 cannot slide to the bottom of described accommodating chute 101, hanging shape completely
State, at this moment, described unit bottom surface 30 is the top (as shown in Figure 2) being in described liquid nitrogen liquid level 70, i.e. described storage element 3
Directly do not contact with described liquid nitrogen 7.It is saved sample is maintained at a higher temperature (relative to directly connecing as such, it is possible to allow
For touching described liquid nitrogen 7, typically at about-20 DEG C).And when packing up described elastic block piece 4, owing to not hindering, described storage
Unit 3 slips into the bottom of described accommodating chute 101 smoothly, i.e. described storage element 3 directly contacts (such as Fig. 3 with described liquid nitrogen 7
Shown in).It is saved sample is maintained at a relatively low temperature as such, it is possible to allow.Thereby, it is achieved the effect of gradient cooling.
Below only have expressed embodiment of the present utility model, it describes more concrete and in detail, but can not therefore and
It is interpreted as the restriction to utility model patent scope.It should be pointed out that, for the person of ordinary skill of the art, not
On the premise of departing from this utility model design, it is also possible to making some deformation and improvement, these broadly fall into guarantor of the present utility model
Protect scope.Therefore, the protection domain of this utility model patent should be as the criterion with claims.
