Abstract
The utility model discloses a kind of liquid nitrogen and move liquid bucket, comprise staving, the bottom of staving is provided with mozzle, and mozzle and staving junction are provided with conical plug, and the top of conical plug is connected to draw ring by montant, and draw ring is positioned at above staving.Mozzle of the present utility model is arranged on the bottom of staving, is convenient to get liquid nitrogen, its reasonable in design from the entrance turnover of narrow and small liquid nitrogen container, simple to operate, safe ready.
Description
Technical field
The utility model relates to a kind of experimental facilities, be specially a kind of applicable laboratory take a morsel liquid nitrogen time the liquid nitrogen that uses move liquid bucket.
Background technology
The laboratories such as current molecule is biochemical, in the experiments such as RNA, DNA extracting, conventional a small amount of liquid nitrogen carrys out quick freezing box maintenance ultralow temperature.General run of thins is less to liquid nitrogen consumption, usually arrives hundreds of milliliter at tens milliliters.And at present usually adopting two kinds of ways to solve in laboratory: a kind of mode is the mode of directly toppling over and another kind of mode is fill with common pail to get.
For the mode that the first is toppled over, liquid nitrogen container is generally heavier, and common lab uses holding vessel all more than three decaliters.During operation, need the larger personnel of strength just can complete, and topple over the very difficult control of liquid measure, be easy to overflow or splashing, not only easily cause a large amount of wastes, more easily cause the injury to operating personal.
Take a morsel with common bucket lift for the second the mode of liquid nitrogen, and when getting liquid nitrogen, liquid nitrogen pours into the mode being through and overflowing in pail above pail and reintroduce and get, and this operating process can cause the liquid nitrogen surface of liquid nitrogen container will experience the process of rise and fall.In tank liquid nitrogen comparatively completely time, rise into liquid nitrogen surface during liquid nitrogen pressing pail containing, be easy to cause liquid nitrogen to overflow danger outside tank.Same this kind of method, the amount of liquid nitrogen of getting also is not easy to control.And when pouring out, need very long in tow pole to tilt, pour out in operation also extremely inconvenient.Flow capacity is also not easy to control, and is easy to spill, and causes danger.These two kinds of modes, use very inconvenient, easily cause danger in a word.
Summary of the invention
The purpose of this utility model is for above problem, provides a kind of liquid nitrogen to move liquid bucket, uses when being applicable to very much pipetting a small amount of liquid nitrogen, its reasonable in design, simple to operate, safe ready.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of liquid nitrogen moves liquid bucket, comprises staving, the bottom of staving is provided with mozzle, mozzle and staving junction are provided with conical plug, and the top of conical plug is connected to draw ring by montant, and draw ring is positioned at above staving.
Be provided with the first spacing ring in described staving, spacing ring is positioned at the top of conical plug, and its internal diameter is less than external diameter bottom conical plug, and montant is through the first spacing ring.By this setting, can carry out spacing to conical plug, prevent from extracting too high or departing from lift route.
Be provided with the second spacing ring above staving, montant is through the second spacing ring, and the below of the second spacing ring is also provided with fixing card, fixedly is positioned on montant, is provided with spring between the second spacing ring and fixing blocks.By the design of the second spacing ring and spring, may be used for the route of the pick up height limiting conical plug on the one hand, on the other hand, can also, by spring Rapid reset after lift, make conical plug block mozzle.
The top of described draw ring is also provided with handle, and it is fixedly connected with staving; Conveniently lift draw ring.
Be provided with buoy in described staving, outside staving, be provided with scale graduation, by the cooperation of buoy and scale graduation, can accurately read liquid nitrogen height, accurately control the amount of pipetting or the use amount of liquid nitrogen.
In the utility model, in staving, each several part all adopts low temperature resistant material to make, as staving can use aluminum to make.
Compared with the utility model gets liquid mode with traditional liquid nitrogen, there is following beneficial effect:
1, compared with moving liquid nitrogen container and topple over the mode of liquid nitrogen, its advantage is:
1) light, in operating personal muscle power without high requirement; 2) saferly prevent from liquid nitrogen from spilling hurting sb.'s feelings; 3) get liquid measure relatively easily to control; 4) avoid liquid nitrogen to waste in a large number.
2, contain with traditional liquid nitrogen pail and get compared with liquid nitrogen, its advantage is:
1) liquid nitrogen flows into from base apertures, and avoiding needs firmly to enter bucket to pressing down pail by bung overflow; 2) avoid, when liquid nitrogen container liquid nitrogen is comparatively expired, getting the accident that liquid causes liquid nitrogen to overflow from tank; 3) in the time of falling liquid nitrogen, liquid nitrogen flows out from bottom, easily controls, operate safer, avoid pail, easily spill liquid nitrogen danger; 4) compared with common pail, this liquid nitrogen moves liquid bucket, liquid nitrogen can be passed in and out bottom being, suitably can add height as required, get liquid with increase to amass, and the difficulty of getting liquid and falling liquid can not be increased, and common pail needs to enter liquid nitrogen from top, tilt to pour out again, the increase along with height will increase gets liquid and the difficulty of falling liquid.
3, this design also may be used for the use that other liquid gets liquid less.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Further illustrate the utility model below in conjunction with embodiment, but the claimed scope of the utility model is not limited to the scope of embodiment statement.
As shown in Figure 1, a kind of liquid nitrogen moves liquid bucket, and the bottom of staving 1 is provided with mozzle 2, and mozzle 2 and staving 1 junction are provided with conical plug 3, and the top of conical plug 3 is connected to draw ring 5 by montant 4, and draw ring 5 is positioned at above staving.
Be provided with the first spacing ring 6 in described staving 1, spacing ring 6 is positioned at the top of conical plug 3, and its internal diameter is less than external diameter bottom conical plug 3, and montant 4 is through the first spacing ring 6.
Be provided with the second spacing ring 7 above staving 1, montant 4 is also provided with fixing card 8 through the below of the second spacing ring 7, second spacing ring 7, and fixing card 8 is positioned on montant 4, is provided with spring 9 between the second spacing ring 7 and fixing card 8.
The top of described draw ring 5 is also provided with handle 10, and it is fixedly connected with staving 1.
Be provided with buoy 11 in described staving 1, outside staving 1, be provided with scale graduation 12.
During use, staving is put into liquid nitrogen container, when touching liquid nitrogen, upwards lift draw ring 5, have liquid nitrogen and enter staving from bottom mozzle, then draw ring 5 is put down, the place of eating dishes without rice or wine that conical plug 3 resets to mozzle by spring and montant blocks it, again staving is proposed from liquid nitrogen container, the outlet of mozzle is aimed at and needs the container adding liquid nitrogen, pull-up draw ring 5 again, liquid nitrogen flows in required container, judges the degree of depth of liquid nitrogen and the amount of liquid nitrogen of outflow in bucket in this process by observation scale graduation 12 and buoy.
