It is further preferred that being arranged at intervals with horizontally disposed demarcation strip in pail, demarcation strip is with pail with detachable side Formula is connected, and liquid drain hole is offered on demarcation strip.

It is further preferred that the bucket inwall both sides of pail are relatively set with guide slide, relative two of guide slide Fluted along short transverse spaced set respectively on side, the side of demarcation strip is relatively set with two bayonet sockets, is set in bayonet socket The spring chuck with fit depressions is equipped with, demarcation strip is caught in the groove of guide slide by the spring chuck set in bayonet socket In.

It is further preferred that pail is cylindric staving, demarcation strip is circular plate body.

Compared to the prior art the utility model, the advantage is that：

The utility model provides a kind of liquid nitrogen pail, can solve the problem that current liquid nitrogen pail is easily unrestrained when in use and is contained The problem of liquid nitrogen and volatile contained liquid nitrogen, the liquid nitrogen pail arrangements are simple, easy to use, are easy to storing samples, and be not easy The unrestrained liquid nitrogen held, can reduce the volatilization of contained liquid nitrogen.

Additional aspect and advantage of the present utility model will be set forth in part in the description, partly by from following description In become obvious, or by it is of the present utility model practice recognize.

Embodiment

The exemplary embodiment of the disclosure is more fully described below with reference to accompanying drawings.Although the disclosure is shown in accompanying drawing Exemplary embodiment, it being understood, however, that may be realized in various forms the disclosure without should be by embodiments set forth here Limited.On the contrary, these embodiments are provided to facilitate a more thoroughly understanding of the present invention, and can be by the scope of the present disclosure Completely it is communicated to those skilled in the art.

In description of the present utility model, it is to be understood that term " longitudinal direction ", " transverse direction ", " on ", " under ", " preceding ", The orientation or position relationship of the instruction such as " rear ", "left", "right", " vertical ", " level ", " top ", " bottom ", " interior ", " outer " be based on Orientation shown in the drawings or position relationship, it is for only for ease of description the utility model, rather than instruction or the dress for implying meaning Put or element there must be specific orientation, with specific azimuth configuration and operation, therefore it is not intended that to the utility model Limitation.

As depicted in figs. 1 and 2, a kind of liquid nitrogen pail that the utility model embodiment provides, including pail 8, suspension rod 1, carry Bar 2, retainer ring 3, extension spring 4, lid 5, retainer ring 3 are fixed with the shaft of suspension rod 1, the bottom of suspension rod 1 is connected with pail 8, shadoof 2 is arranged in retainer ring 3, and the bottom of shadoof 2 is connected with one end of extension spring 4, and lid is hinged with the bung of pail 8 Son 5, lid 5 is connected with the other end of extension spring 4.The liquid nitrogen pail that the utility model embodiment provides can be used for from liquid nitrogen container Interior Sheng takes liquid nitrogen, when taking liquid nitrogen using liquid nitrogen pail Sheng, first holds suspension rod 1, the pail 8 for making to be connected with suspension rod 1 immerses liquid In liquid nitrogen in nitrogen tank, during extracting liquid nitrogen, by the length of the lifting restrained stretching spring 4 of shadoof 2, so as to control lid The opening and closing of son 5.Shadoof 2 is pulled, lid 5 is opened, and Sheng takes liquid nitrogen；Shadoof 2 is unclamped, lid 5 covers, by liquid nitrogen bucket lift to liquid nitrogen Outside tank.By adding lid, pail 8 can be caused when being moved to other regions outside liquid nitrogen container in the case of filling with liquid nitrogen, liquid Nitrogen will not splash away, while decrease the volatilization of liquid nitrogen so that experiment is safer, can also save liquid nitrogen.

Horizontally disposed demarcation strip 6 is arranged at intervals with pail 8, demarcation strip 6 is removably connected with pail 8, point Liquid drain hole 7 is offered on dividing plate 6.Demarcation strip 6 in liquid nitrogen pail is removably connected in pail 8, when needing to freeze When depositing multiple samples, variant Sample storage can be made by the compartmentation of demarcation strip 6 to demarcation strip different zones about 6, and Liquid drain hole 7 is distributed with demarcation strip, can be so that the heat that sample is run out be dissipated as early as possible by liquid drain hole 7 when freezing sample Go, be unlikely to wash open demarcation strip.Then demarcation strip can also be disassembled when needing Sheng to take outside liquid nitrogen to liquid nitrogen container.

The bucket inwall both sides of pail 8 are relatively set with guide slide 9, distinguish on two relative sides of guide slide 9 Along short transverse spaced set fluted 10, the side of demarcation strip 6 is relatively set with two bayonet sockets 11, is provided with bayonet socket 11 The spring chuck 12 being engaged with groove 10, demarcation strip 6 are caught in guide slide 9 by the spring chuck 12 set in bayonet socket 11 In groove 10.The spring chuck 12 set at the bayonet socket 11 of demarcation strip 6 can be compressed in the presence of external force pressure, be moved to Demarcation strip 6 to guide slide 9 groove when, spring chuck 12 restore to the original state enter in groove, so as to realize demarcation strip 6 Altitude location, demarcation strip 6 such as need to be adjusted or dismantled again, then firmly can push or pull up demarcation strip 6, the Spring Card of demarcation strip 6 First 12 extrude under external force, so as to be separated the position adjustment of plate 6, while can be easily by demarcation strip 6 from pail 8 In remove, it is convenient and swift.

In the utility model embodiment, pail 8 is cylindric staving, and demarcation strip 6 is circular plate body.

In summary, the liquid nitrogen pail that the utility model embodiment provides, can solve the problem that current liquid nitrogen pail is using When easily unrestrained the problem of containing liquid nitrogen and volatile contained liquid nitrogen, the liquid nitrogen pail arrangements are simple, easy to use, are easy to deposit Sample, and the unrestrained liquid nitrogen held is not easy, the volatilization of contained liquid nitrogen can be reduced.

While there has been shown and described that embodiment of the present utility model, it will be understood by those skilled in the art that： These embodiments can be carried out with a variety of changes, modification in the case where not departing from principle and objective of the present utility model, replaced And modification, the scope of the utility model are limited by claim and its equivalent.
