Description
Technical field
The utility model belongs to experiment appliance field, is mainly used in when antigen prepares freeze thawing and centrifuge tube is put into liquid nitrogen container, make centrifuge tube stable to put into liquid nitrogen freezing, be specifically related to a kind ofly be convenient to the hand basket that centrifuge tube puts into liquid nitrogen container.
Background technology
Liquid nitrogen container hand basket is a kind of low-temperature storage instrument, be used at low ambient temperatures (liquid nitrogen container) store cryopreservation tube, so that storage experiment sample that can be a large amount of.
Tumour cell need be put into liquid nitrogen when prepared by antigen freezing, then by tumour cell 37 DEG C thawing, multigelation, obtains antigen.When preparing a large amount of antigen, tumour cell is placed in centrifuge tube that operation is very easy, but due to liquid nitrogen container hand basket for cryopreservation tube designs, is placed in hand basket so centrifuge tube can not be stable, exist such as centrifuge tube put into liquid nitrogen container freezing time the problem such as unstable, urgently to be resolved hurrily.
According to the retrieval, the patent document of existing liquid nitrogen container hand basket is as follows:
CN203388149U discloses a kind of liquid nitrogen container cryopreservation tube hand basket, it by: handle, connecting rod, basket lid, hand basket frame, cryopreservation tube fixing hole, base are formed.Handle is connected with one end of connecting rod, and basket lid is sleeved on connecting rod, and the other end of connecting rod is arranged on hand basket frame and base, and hand basket frame is provided with cryopreservation tube fixing hole.This product structure is simple, and reasonable in design, cryopreservation tube is fixed on hand basket frame, cryopreservation tube is not easily obscured, floating, cryopreservation tube can be accessed safely, fast, easily in liquid nitrogen container, easy to operate, save time, laborsaving, effectively prevent experimenter's frostbite, save liquid nitrogen.
CN203865247U discloses a kind of sample access device for liquid nitrogen container, and described sample access device comprises hand basket part and sample box lifting part; Described hand basket part comprises hand basket framework, joint sleeve and drop handle, and hand basket framework comprises the cavity that barrel wall and bucket wall surround; Bucket wall is provided with the hole of some applicable fluid turnover; On the outer wall of the bucket wall left and right sides, corresponding position is provided with the sleeve pipe be fixedly connected with, and the two ends, left and right of described drop handle are each passed through two described sleeve pipes, and the end at two ends, drop handle left and right is fixedly connected with the postioning abutment preventing drop handle from deviating from from sleeve pipe respectively; Described sample box lifting unit divides and is arranged in hand basket cavity, comprise the chain wheel transmission shaft, sprocket wheel and the carrying chain that form chain type transmission structure, chain wheel transmission shaft is fixed in the axis hole that on hand basket framework, front and back are oppositely arranged, and chain wheel transmission shaft two ends are provided with rocking handle jack; With drive sprocket power transmission shaft in rocking handle jack during use, rocking handle being inserted chain wheel transmission shaft, chain wheel transmission shaft drives the sprocket wheel be fixedly connected with it, and sprocket wheel drives carrying chain by the gear teeth on it; Carrying chain is fixedly connected with sample box base plate, and sample box base plate is provided with bottom outlet, and the other end of sample box is sample access mouth, is provided with the end cap that can open.
Although said apparatus also solves this problem, its scheme is different from the application, and the effect of acquisition is different, does not affect novelty and the creativeness of application.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art part, provide a kind of structure simple, practical and convenient be convenient to the hand basket that centrifuge tube puts into liquid nitrogen container.
The technical scheme that the utility model realizes object is as follows:
A kind ofly be convenient to the hand basket that centrifuge tube puts into liquid nitrogen container, comprise handle and hand basket frame, hand basket frame Upper vertical installs handle, for lifting whole hand basket frame, be shaped with two draw-in grooves in upper and lower interval at hand basket frame two respectively to inside sidewalls, draw-in groove between two level is relative, setting-in square card dish in the two relative draw-in grooves on top, be shaped with centrifuge tube fixing hole in the middle part of chuck, centrifuge tube passes in hole, the square pallet of setting-in in two relative draw-in grooves of bottom.
And, in pallet, place grid.
The beneficial effects of the utility model are:
The hand basket of what the application provided be convenient to centrifuge tube puts into liquid nitrogen container can meet the needs that some centrifuge tubes (15ml or 50ml) short time puts into the freezing experiment of liquid nitrogen (as prepared by antigen), make centrifuge tube can be stable freezing in liquid nitrogen container, unlikely inclination is even dropped in liquid nitrogen container, for the freezing of heavy dose of sample is provided convenience, there is efficient, quick, safe feature.
The hand basket of what the application provided be convenient to centrifuge tube puts into liquid nitrogen container provides a kind of hand basket for centrifuge tube practicality first, has enriched kind and the function of hand basket.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is that the A-A of Fig. 1 is to cutaway view;
Fig. 3 is that the B-B of Fig. 1 is to cutaway view.
Embodiment
Below in conjunction with accompanying drawing, also by specific embodiment, the utility model is described in further detail, and following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
A kind ofly be convenient to the hand basket that centrifuge tube puts into liquid nitrogen container, comprise handle 1 and hand basket frame 2, hand basket frame Upper vertical installs handle, for lifting whole hand basket frame, places it in liquid nitrogen container, two draw-in grooves 5 are shaped with in upper and lower interval respectively to inside sidewalls at hand basket frame two, draw-in groove between two level is relative, and setting-in square card dish 3 in the two relative draw-in grooves on top, is shaped with centrifuge tube fixing hole 6 in the middle part of chuck, the square pallet 4 of setting-in in two relative draw-in grooves of bottom, places grid 7 in pallet.
