Description
Technical field
The utility model relates to a kind of rack for test tube, particularly relates to a kind of rack for test tube device being easy to the complete transfer liquid of instrument.
Background technology
Sample introduction needle sampling is the sampling technique that analytical instrument the most often adopts, is generally enter sample tube pipette samples by driven by motor metal sample introduction needle.This sample introduction needle sampling technique has sample introduction needle to contact bottom sample tube and sample introduction needle to decline two kinds of sampling modes with liquid level.The key of the sampling mode bottom sample introduction needle contact sample tube is the laminating bottom sample introduction needle needle point and test tube, but poke test tube to prevent sample introduction needle, need to make to keep certain gap bottom sample introduction needle and test tube, therefore the sample in test tube cannot reach and shift completely, causes the accuracy of ultimate analysis result to decline.And the sampling mode that sample introduction needle declines with liquid level needs the sample volume prepared to be fixing, and general all far away more than the volume of actual required sampling, and therefore this mode can waste sample undoubtedly, also cannot realize the transfer completely of sample in test tube simultaneously.
Summary of the invention
For the problems referred to above, the purpose of this utility model is to provide one and both can effectively prevented sample introduction needle from poking test tube, can be easy to again the rack for test tube device of the complete transfer liquid of instrument.
For achieving the above object, the utility model takes following technical scheme: a kind of rack for test tube device being easy to the complete transfer liquid of instrument, it is characterized in that, comprise rack for test tube upper plate, rack for test tube joint pin, rack for test tube guide plate, elastic buffering pad and rack for test tube base plate, described rack for test tube upper plate, rack for test tube guide plate, elastic buffering pad and rack for test tube base plate are connected in turn on described rack for test tube joint pin from top to bottom, described rack for test tube upper plate and described rack for test tube guide plate are that interval is arranged, described rack for test tube guide plate, elastic buffering pad offsets with rack for test tube base plate order and is connected, described rack for test tube upper plate and rack for test tube guide plate are also provided with multiple through hole correspondingly, described through hole on described rack for test tube upper plate and rack for test tube guide plate matches with described elastic buffering pad, to form the accommodation space placing sample tube, described elastic buffering pad forms the bottom of described accommodation space.
Described elastic buffering pad adopts polytetrafluoro frothing foam to make.
Described rack for test tube upper plate, rack for test tube guide plate, elastic buffering pad and rack for test tube base plate are provided with multiple installing hole, described rack for test tube upper plate, rack for test tube guide plate, elastic buffering pad are connected as a whole with rack for test tube base plate with the installing hole on rack for test tube base plate through described rack for test tube upper plate, rack for test tube guide plate, elastic buffering pad, and are fixed by multiple interior hexagonal by many described rack for test tube joint pins respectively successively.
Described rack for test tube upper plate and rack for test tube guide plate all adopt polyformaldehyde to make.
Described rack for test tube connecting rod and rack for test tube base plate all adopt metal material to make.
The utility model is owing to taking above technical scheme, it has the following advantages: the utility model employing arranges elastic buffering pad and contacts the mode sampling bottom sample tube and combine with sample introduction needle, can effectively prevent sample introduction needle from poking test tube, achieve the transfer completely of sample liquids in test tube, thus avoid the shortcoming of the reduction of analysis result accuracy and sample waste.
Accompanying drawing explanation

Fig. 2 is assembly structure schematic diagram of the present utility model.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in detail.
As shown in Figure 1, the rack for test tube device of what the utility model provided the be easy to complete transfer liquid of instrument, it comprises rack for test tube upper plate 1, rack for test tube joint pin 2, rack for test tube guide plate 3, elastic buffering pad 4 and rack for test tube base plate 5, rack for test tube upper plate 1, rack for test tube guide plate 3, elastic buffering pad 4 and rack for test tube base plate 5 are connected in turn on rack for test tube joint pin 2 from top to bottom, and rack for test tube upper plate 1 and rack for test tube guide plate 3 are arranged for interval, rack for test tube guide plate 3, elastic buffering pad 4 and rack for test tube base plate 5 then order offset and are connected.Simultaneously, rack for test tube upper plate 1 and rack for test tube guide plate 3 are also provided with multiple through hole correspondingly, through hole on rack for test tube upper plate 1 and rack for test tube guide plate 3 matches with elastic buffering pad 4, to form the accommodation space placing sample tube, and elastic buffering pad 4 forms the bottom of this accommodation space.
In above-described embodiment, elastic buffering pad 4 adopts elastic deformation comparatively large and the nonmetallic materials can recovering elastic deformation ability stronger are made, such as polytetrafluoro frothing foam.
As shown in Figure 1, in above-described embodiment, four angles of rack for test tube upper plate 1, rack for test tube guide plate 3, elastic buffering pad 4 and rack for test tube base plate 5 are provided with an installing hole (only as example, be not limited to this), rack for test tube upper plate 1, rack for test tube guide plate 3, elastic buffering pad 4 are connected as a whole with rack for test tube base plate 5 with the installing hole on rack for test tube base plate 5 through rack for test tube upper plate 1, rack for test tube guide plate 3, elastic buffering pad 4, and are fixed by four interior hexagonals by four rack for test tube joint pins 2 respectively successively.
In above-described embodiment, rack for test tube upper plate 1 and rack for test tube guide plate 3 all adopt polyformaldehyde to make, polyformaldehyde is one of general engineering plastic, have high mechanical property and excellent electrical insulating property, solvent resistance and machinability, rack for test tube upper plate 1 or rack for test tube guide plate 3 and the through hole on it can one machine-shapings very easily; Certainly, rack for test tube upper plate 1 and rack for test tube guide plate 3 also can adopt other nonmetallic materials suitable with polyformaldehyde performance to make.
In above-described embodiment, rack for test tube connecting rod 2 and rack for test tube base plate 5 all adopt metal material to make, such as stainless steel.
In use, sample tube is placed in the accommodation space that through hole on rack for test tube upper plate 1 and rack for test tube guide plate 3 and elastic buffering pad 4 form the utility model, and the bottom of sample tube contacts with elastic buffering pad 4.When sample introduction needle enters sample tube pipette samples liquid, due to the elastically-deformable performance of bottom resilient cushion pad 4, the pressure be subject to bottom sample tube is absorbed by elastic buffering pad 4, can effectively prevent from being poked by sample introduction needle because pressure is excessive bottom sample tube, make sample introduction needle can fit tightly the bottom of sample tube, thus the gap between completely eliminating bottom sample introduction needle and sample tube, ensure that the liquid in sample tube is shifted completely, avoid the shortcoming of sample waste and the reduction of analysis result accuracy.
The various embodiments described above are only for illustration of the utility model; wherein the structure, connected mode etc. of each parts all can change to some extent; every equivalents of carrying out on the basis of technical solutions of the utility model and improvement, all should not get rid of outside protection domain of the present utility model.
