Into inconvenience, and due to the reason of platy structure wall thickness, cause freezing efficiency low.
Utility model content
For overcome the deficiencies in the prior art, the purpose of this utility model is that providing one kind effectively prevents cryopreservation tube from taking off
Go out, and the liquid nitrogen container hand basket of good cooling results.
To solve the above problems, technical scheme is as follows used by the utility model：
A kind of liquid nitrogen container hand basket, including tray, lid and shadoof, the tray includes inner disc and external disk, described interior
Connected between disk and external disk by fix bar, the putting hole for placing cryopreservation tube, institute are offered on the inner disc and external disk
State putting hole bottom and offer through hole, the diameter of the through hole is less than the diameter of putting hole, and the tray is multiple, is gone here and there successively
Be located on shadoof, the lid be located on shadoof and it is movable be connected on the tray of the top, the lid is netted
Structure.
Preferably, the cell body connected with the putting hole is offered in the side wall of the inner disc and external disk.
Preferably, the width of the cell body is less than the diameter of putting hole.
Preferably, the length of the cell body is less than the depth of putting hole.
Preferably, the cell body is opened on the madial wall and lateral wall of external disk.
Preferably, external screw thread is provided with the shadoof, the lid is spirally connected with shadoof.
Compared with prior art, the beneficial effects of the utility model are：Inner disc and external disk split are used in the utility model
Set, putting hole bottom offers through hole, and because internal and external disk sidewall thickness substantially reduces, and liquid nitrogen can connect from bottom and cryopreservation tube
Touch, raising freezes efficiency, and being beneficial to liquid nitrogen when lifting hand basket flows out, and reduces the loss of liquid nitrogen；The lid of network structure can prevent from freezing
Deposit pipe out of putting hole to deviate from, and further improve and freeze efficiency.

Fig. 2 is the use state figure of liquid nitrogen container hand basket in Fig. 1；
Fig. 3 is the structural representation of liquid nitrogen container hand basket in another embodiment of the utility model；
Wherein, 100 it is tray, 11 be external disk, 12 be inner disc, 13 be fix bar, 2 be putting hole, 21 be cell body, 3 is
Lid, 4 be shadoof, 5 be motion bar, 51 be the first motion bar, 52 be the second motion bar, 53 be rotating shaft.
Embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
As shown in Figure 1, 2, it is a kind of liquid nitrogen container hand basket in the utility model preferred embodiment, including tray 100, lid
3 and shadoof 4, tray 100 include inner disc 11 and external disk 12, connected between inner disc 11 and external disk 12 by fix bar 13, inner disc
11 and external disk 12 on offer putting hole 2 for placing cryopreservation tube, the one end of shadoof 4 is fixed on the center of tray 100, covers
Body 3 is located on shadoof 4 and movable is connected on tray 100.Using inner disc 11 and the split settings of external disk 12, the He of inner disc 11
After setting putting hole 2, tray 100 to be put into liquid nitrogen container in external disk 12 respectively, because internal and external disk sidewall thickness substantially reduces, put
The freezing efficiency for putting the cryopreservation tube in hole 2 greatly improves, and when hand basket is lifted, will not excessively take liquid nitrogen out of, reduces liquid nitrogen
Loss；Lid 3 can prevent cryopreservation tube from deviating from out of putting hole 2.
Further, the cell body 21 connected with putting hole 2, the width of cell body 21 are offered in the side wall of inner disc 11 and external disk 12
Degree is less than the diameter of putting hole 2, and the length of cell body 21 is less than the depth of putting hole 2.After cryopreservation tube is put into putting hole 2, liquid
Nitrogen through cell body 21 can diameter and it is cold deposit pipe contact, further increase and freeze efficiency.
Further, cell body 21 is opened on the madial wall and lateral wall of external disk 11, is further increased liquid nitrogen and is deposited pipe with cold
Contact area.
Further, the bottom of putting hole 2 offers through hole, and the diameter of through hole is less than the diameter of putting hole 2, and liquid nitrogen can be the bottom of from
Portion contacts with cryopreservation tube, and raising freezes efficiency, and is beneficial to liquid nitrogen during for lifting hand basket and flows out, and reduces the loss of liquid nitrogen.
Specifically, stability during in order to ensure that lid 3 abuts with tray 100, places cryopreservation tube and is taken off out of putting hole 2
Go out, external screw thread is provided with shadoof 4, lid 3 is spirally connected with shadoof 4, stabilization during so as to realize that lid 3 abuts with tray 100
Property.Fixed it should be understood that can also be realized between lid 3 and shadoof 4 by snap fit.
Specifically, the other end of shadoof 4 is connected with motion bar 5, motion bar 5 includes the first motion bar 51 and the second motion bar
52, one end of the first motion bar 51 and the second motion bar 52 is pivotally connected by rotating shaft 53 and shadoof 4, and the first motion bar 51 and second is lived
Lever 52 collectively forms motion bar 5 when overlapping, the diameter of motion bar 5 is not more than the diameter of shadoof 4.As long as in this way, in liquid nitrogen cover
One and the diameter identical hole of shadoof 4 are opened up on body, motion bar 5 is passed through, and by the first motion bar 51 and the second motion bar 52
(as shown in Figure 2) is rotated to different directions, you can realize the fixation of shadoof 4, and shadoof 4 is just by liquid nitrogen container lid respectively
Hole seals, and ensure that liquid nitrogen does not leak.
In order to ensure the durability of hand basket, tray 100 and lid 3 are stainless steel.
