Description
Technical field
This utility model is related to cryopreservation tube storage device technical field, the more particularly to liquid of cryopreservation tube hand basket wall-embedded storage
Nitrogen tank.
Background technology
Liquid nitrogen cryopreservation is one of biological cell, tissue, organ preservation main method, among liquid nitrogen derives from air, air
Included in major gaseous component have oxygen and nitrogen.Wherein, nitrogen accounts for the 78.09% of air, and liquid nitrogen as liquefies
Nitrogen.Due to the ultralow warm nature of nitrogen, dilatancy and asphyxiating, it is commonly used for industrial.Frozen sample will be often needed to put
Preserve in -196 DEG C of liquid nitrogen, can be stored in cell detachment growth conditions situation.
Liquid nitrogen container is commonly called as biological liquid nitrogen container, can be used for medical treatment, biological study, colleges and universities' experiment, chromatography experiment and epidemic prevention single
Position.Mainly as storage type liquid nitrogen container in terms of medical treatment and scientific research, preserve cattle seminal fluid, embryo, do thin for indoor long-time
Born of the same parents, skin, internal organs, vaccine isoreactivity biomaterial.Prior art generally stores experimental specimen using cryopreservation tube, will be frozen
Pipe is positioned in hand basket frame, and hand basket frame is hung over liquid nitrogen container plug mouth inward flange by shadoof then, with reeded tank plug envelope
Tank mouth is closed, specimen is fully contacted with liquid nitrogen, reach frozen effect.
But in above-mentioned existing design, hand basket hangs over the marginal position that the inward flange of liquid nitrogen container plug mouth can take tank mouth,
Reduce the actually used diameter of tank mouth.Meanwhile, using with groove corresponding with handle shape, must block when tank plug is closed
Buckle into corresponding position, it is desirable to minimum machine error and operating error, no person can extrude tank plug deforms which, impact subsequently makes
With.
Utility model content
The purpose of this utility model is the liquid nitrogen container for providing the storage of cryopreservation tube hand basket wall-embedded, solves existing storage frozen
The liquid nitrogen container of pipe is used for the problem in the handle occupancy tank mouth space for hanging hand basket.
For achieving the above object, above-mentioned technique effect is reached, this utility model solves above-mentioned asking by the following technical programs
Topic：
Cryopreservation tube hand basket wall-embedded storage liquid nitrogen container, including tank body, the tank plug for closed tube and have hook
Hand basket, the tank mouth inwall at the top of the tank body is provided with hanging groove, and the hook is embedding to be hung in hanging groove.Extension is opened up in the inwall of tank mouth
Groove, will place with hanging groove for the hook for hanging hand basket, hook can be made to be hidden in groove, the space of tank mouth is not take up, so as to
The actually used size of tank mouth is not affected.The more above-mentioned existing inward flange that hand basket is hung over tank mouth, arranges slotted eye on stopper
The space increase of hand basket for liquid nitrogen container, is extracted, is operated more flexible.
Used as the improvement of the liquid nitrogen container of the above-mentioned cryopreservation tube hand basket wall-embedded storage of this utility model, the hanging groove includes tank mouth
The cell body of inwall vertical direction, extends to the horizontal cell body at top from vertical direction.That what is linked up with is entirely affiliated to partly all embedding being hung on
In groove, it is entirely avoided hand basket links up with the impact to tank mouth, extract each hand basket and do not interfere with each other, be not take up mutual space.
Used as the improvement of the liquid nitrogen container of the above-mentioned cryopreservation tube hand basket wall-embedded storage of this utility model, the tank plug includes top
Cock cap, the stopper rod being connected with cock cap bottom, cock cap and stopper rod junction are provided with O-ring seal.Sealing ring is that have necessarily
Deformability be usually used in the component that mechanical part prevents the leakage of liquids and gases medium in a static condition.The tank under lid
After plug, using the elasticity and resilience of sealing ring, the gap between hook and hanging groove is made up, nitrogen can be effectively prevented
Leak.
As the improvement of the liquid nitrogen container of the above-mentioned cryopreservation tube hand basket wall-embedded storage of this utility model, the embedding extension section of the hook
It coincide with hanging groove.Either existing method will link up with embedding extension with the tank plug that groove is matched with shadoof, or this utility model
In hanging groove, all try to further improve the air-tightness of liquid nitrogen container.In the case where sealing ring is arranged, it is processed further making
It is embedding to hang section and the identical gap spilling that preferably prevent the nitrogen in liquid nitrogen container between hook and hanging groove of hanging groove, improve liquid
The frozen effect of nitrogen tank.
As the improvement of the liquid nitrogen container of the above-mentioned cryopreservation tube hand basket wall-embedded storage of this utility model, the plug of the tank plug bottom
Bar and tank mouth minor diameter fit, surface is not provided with groove.It is hung on the hook of hand basket embedding in hanging groove, hand basket hook is not take up tank mouth
Using space, the tank plug matched with the internal diameter of tank mouth using sectional dimension and shape can reach preferable sealing effectiveness.Meanwhile, this
Sample design makes lid press operation easy, is not required to check the position between tank plug and each hand basket, reduces machine error and operating error
The inconvenience for bringing.
The beneficial effects of the utility model are：
1st, hanging groove is set in tank mouth inwall, will places with hanging groove for the hook for hanging hand basket, tank mouth reality will not be changed
Border uses size, provides bigger space to operation is extracted.
2nd, cock cap and stopper rod junction are provided with O-ring seal, using sealing ring elasticity and resilience, to hook and
Gap between hanging groove is made up, and can effectively prevent leaking for nitrogen.
The 3rd, stopper rod with tank mouth minor diameter fit is set, becomes easy using the operation of closed tank, be not required to check and each
Position between hand basket.
The liquid nitrogen container of the cryopreservation tube hand basket wall-embedded storage provided by this utility model, can preferably be solved existing storage and be frozen
Deposit the problem that handle of the liquid nitrogen container of pipe for hanging hand basket takes tank mouth space.
