Description
Technical field
The utility model relates to a kind of biological sample Excised Embryos device, belongs to test tool technical field, is a kind of liquid nitrogen cryopreservation bucket specifically.
Background technology
Many biological samples or organization need are preserved under the condition of ultralow temperature of liquid nitrogen, and to ensure the quality of sample, therefore liquid nitrogen container becomes the major way of field sampling and laboratory storing samples, is widely used.The common pail that in existing liquid nitrogen container, the frozen bucket of storing samples is normally uncovered, this easy pail has the simple advantage of use, but its shortcoming is fairly obvious, namely after fresh sample is put into, can not fast pail be put in liquid nitrogen container, otherwise sample refrigerating process puts thermogenetic boiling-like can overflow pail by sample, falls in liquid nitrogen container, be difficult to take out.Therefore, must wait for sample in pail after complete release heat sinking, could be put in liquid nitrogen container by pail, take time and effort, especially when sample size is larger, this problem is particularly outstanding.
Summary of the invention
The problems referred to above that the utility model exists for prior art, provide a kind of liquid nitrogen cryopreservation bucket, can put into liquid nitrogen container at once and preserve after making biological sample sampling put into frozen bucket, and need not wait for that sample releases heat, ensure that sample can not overflow frozen bucket, its structure is simple, simple operation.
The purpose of this utility model is achieved through the following technical solutions:
A kind of liquid nitrogen cryopreservation bucket, comprise: the staving that shadoof, upper end are uncovered, described staving comprises at the bottom of a barrel wall, bucket, have liquid drain hole at the bottom of described bucket, it is characterized in that: be hinged outside described shadoof lower end and described bucket wall, have the edge of a bung to be fixed on the middle part of described shadoof, the vertical state of described shadoof, the upper end that described bung closes described staving is uncovered, and the outward-dipping state of described shadoof, the upper end that described bung leaves described staving is uncovered.
Improvement to technique scheme: horizontally set one stationary shaft on described bucket wall lateral surface, the lower end of described shadoof arranges an axis hole, described shadoof by axis hole and stationary shaft and bucket wall hinged, on stationary shaft, also cover has a torsion spring, one end of described torsion spring is fixed on shadoof, the other end is fixed on barrel wall, and described bung equals the uncovered distance to stationary shaft in upper end of staving to the distance of stationary shaft.
Further improvement to technique scheme: described bung has bleeder vent.
Further improvement to technique scheme: described staving is the round tank that stainless steel is made, described bung is the stamping forming circular lid of stainless steel, and described shadoof is that stainless-steel tube is made.
Advantage of the present utility model and good effect are:
Bung can be covered after biological sample being put into liquid nitrogen cryopreservation bucket of the present utility model at once put into liquid nitrogen container and preserve, liquid nitrogen enters in bucket from the liquid drain hole at the bottom of bucket, sample refrigerating process puts thermogenetic gas by the bleeder vent discharge on bung, there will not be bung to wash open, sample overflow problem, improve sample quality.Being wholely set of bung and shadoof is convenient to singlehanded pail and is uncapped, and sampling when the frequency is many, sample size is large and can saving time, improves sampling work efficiency.

Embodiment
For making the object of the utility model embodiment, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the utility model embodiment, technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Below in conjunction with accompanying drawing, the utility model is described in further detail:
See Fig. 1-Fig. 4, the embodiment of a kind of liquid nitrogen cryopreservation bucket of the utility model, comprising: the staving that shadoof 1, upper end are uncovered, and described staving to comprise at the bottom of barrel wall 4, bucket 5, at the bottom of bucket, respectively have some liquid drain holes 8 on 5.Hinged outside described shadoof 1 lower end and described bucket wall 4, there is the edge of a bung 2 to be fixed on the middle part of described shadoof 1.When shadoof 1 vertically state, the upper end uncovered 3 that described bung 2 closes described staving, when the outward-dipping state of shadoof 1, bung 2 leaves the upper end uncovered 3 of described staving.
Specifically, horizontally set one stationary shaft 6 on lateral surface in the middle part of bucket wall 4, the lower end of shadoof 1 arranges an axis hole 10, shadoof 1 passes through axis hole 10 kink of lower end on stationary shaft 6, outside stationary shaft 6, also cover has a torsion spring 7, one end of torsion spring 7 is fixed on shadoof 1, and the other end of torsion spring 7 is fixed on barrel wall 4.The edge of a bung 2 is had to be fixed on in the middle part of shadoof 1, and vertical with shadoof 1, bung 2 equals the distance of upper end uncovered 3 to stationary shaft 6 to the distance of stationary shaft 6.Put thermogenetic gas to enable sample refrigerating process to emerge, bung 2 has some bleeder vents 9.
Above-mentioned staving is the round tank that stainless steel is made, and above-mentioned bung 2 is the stamping forming circular lid of stainless steel, and above-mentioned shadoof 1 is made for stainless-steel tube.
During use, pulled outward by the shadoof 1 of liquid nitrogen cryopreservation bucket and tilt to appropriate location, the bung 2 be now fixed on shadoof 1 departs from the upper end uncovered 3 of liquid nitrogen cryopreservation bucket, and the upper end uncovered 3 of liquid nitrogen cryopreservation bucket is opened, as shown in Figure 1, sample is directly put into liquid nitrogen cryopreservation bucket.Then, the outside plate power of slow release shadoof 1, under the effect of torsion spring 7, the shadoof 1 of liquid nitrogen cryopreservation bucket is returned to original position, and bung 2 returns to the state covered uncovered for upper end 3, as shown in Figure 2.Liquid nitrogen cryopreservation bucket is directly put into liquid nitrogen to fill with, liquid nitrogen enters in liquid nitrogen cryopreservation bucket by the liquid drain hole 8 at the bottom of bucket on 5, due to bung 2 having bleeder vent 9, there will not be the problem that bung 2 is washed open by the fluidized state of sample refrigerating process heat release.When taking out sample, operate the same, unlike with tweezers, sample is taken out from liquid nitrogen cryopreservation bucket.
Being wholely set of bung 2 and shadoof 1 is convenient to singlehanded pail and is uncapped, and sampling when the frequency is many, sample size is large and can saving time, improves sampling work efficiency.
Certainly, above-mentioned explanation is not to restriction of the present utility model, and the utility model is also not limited to above-mentioned citing; those skilled in the art; in essential scope of the present utility model, done change, remodeling, interpolation or replacement, also should belong to protection domain of the present utility model.
