The utility model discloses the method is simple, and is both in large quantity than the test tube is placed to ordinary test -tube rack, can place the graduated flask again, reduce that the graduated flask is broken or in it medicine pour down or forth danger, can be better be applied to the actual production and use in the middle of.

Description

A kind of test tube stand

【Technical field】

The utility model belongs to experiment appliance field, is related to the improvement to commonly using rack for test tube in current chemical experiment room, tool Body includes the plastics clip of Double-layer test tube frame and extension, and the latter is except can be mainly used in placing graduated cylinder in addition to holding test tubes.

【Background technology】

At present, the conventional rack for test tube in chemical experiment room typically only places individual layer test tube.It is less for sample size Laboratory, its rack for test tube used can also meet demand.For most colleges and universities, research unit, especially third party testing agency etc. is big The laboratory of batch quantity analysis sample is then difficult to meet demand.

In addition, most laboratory has no corresponding rack for test tube to place graduated cylinder, be especially contained with the graduated cylinder of medicine, it is various not Safety factor topples over can graduated cylinder, or breaks or make to hold medicine in it and spill, so as to endanger the personal safety of experimenter.

A kind of test tube stand of applicant's design, can help solve the problems, such as the above.

【The content of the invention】

In order to solve the defect of common test tube frame holding test tubes negligible amounts, while and reduce graduated cylinder break and hold in it The probability that liquid spills, the utility model provides a kind of rack for test tube, not only increases the quantity of holding test tubes, and its epitaxy part Point plastics clip can place graduated cylinder, become " cylinder rack ", can guarantee that the safety for artificially not knocked over and being brought because of graduated cylinder is hidden again Suffer from.

The utility model relates generally to the rack for test tube of two kinds of sizes, makes a concrete analysis of and is described below：

Commonly use the specification such as Tables 1 and 2 of test tube (now by taking colorimetric cylinder as an example) and graduated cylinder in laboratory.The conventional ratio of reference laboratory The specification and size (mainly height and external diameter) of colour tube and graduated cylinder, the utility model rack for test tube may be designed as two kinds of different chis It is very little：(1) diameter 20mm, individual layer test tube is highly 200mm, and total height is the rack for test tube of 400mm --- for placing 10 and 25mL Colorimetric cylinder and 5,10 and 25mL graduated cylinders；(2) a diameter of 30mm, individual layer rack for test tube is highly 300mm, and total height is the examination of 600mm Pipe support --- for placing 50mL colorimetric cylinders and 50 and 100mL graduated cylinders.The specification and reference of the conventional colorimetric cylinder in laboratory and graduated cylinder Size is shown in Table 1 and 2.

The specification and reference dimension of the conventional colorimetric cylinder in the laboratory of table 1

The specification and reference dimension of the conventional graduated cylinder in the laboratory of table 2

Technical solution adopted in the utility model is as follows：

A kind of test tube stand mainly include 6 long transverse slats (wherein 4 have hole, 2 it is non-porous), 6 hyphen plates and 2 it is perpendicular Row's support.6 hyphen plates (wherein 4 have hole, have plastics clip, and 2 non-porous) are epitaxial part；2 vertical setting of types supports with it is all Transverse slat is vertical.Essential structure of 1st and 4 layer of transverse slat and the fixation of 2 vertical setting of types supports from top to bottom as New test tube；

2nd, 3 and 5 layers of long and short transverse slat are movable transverse slat, can be realized insertion and be extracted by draw-in groove.The modeling of extension transverse slat Material clip is mainly used in placing graduated cylinder.

The utility model solves the technical scheme that its technical problem adopted：Individual layer rack for test tube can be only placed original On the basis of devise the test tube stand that can place Double-layer test tube, its epitaxial part draws several transverse slats with plastics clip It is mainly used in placing graduated cylinder.

Have the beneficial effect that：The utility model can be regarded as " two live ", i.e., horizontal version " work " in the middle of rack for test tube --- and it is detachable, Place the range " work " of graduated cylinder --- controlled by plastics clip；The former can increase the quantity of holding test tubes, and the latter can place graduated cylinder, Increased graduated cylinder to be knocked over by unsafe factor and break or spill the safety coefficient of its interior medicine.

【Description of the drawings】The utility model is further described below in conjunction with the accompanying drawings：

Fig. 1 is the essential structure of test tube stand.

Fig. 2 is the general principle figure of test tube stand.

Fig. 3 is the complete construction figure of test tube stand.

1-6 is that, for the transverse slat of holding test tubes frame, wherein 1,2 and 4,5 have hole, 3 and 6 is non-porous；7 is two trapezoidal perpendicular Plate, for fixing 1-6 transverse slats；8 is plastics clip；1 ' -6 ' be hyphen plate with trapezoidal riser vertical epitaxial, wherein 1 ', 2 ' and 4 ', 5 ' there is hole, have a plastics clip, it is 3 ' and 6 ' non-porous, without plastics clip.

【Specific embodiment】

Principle of the present utility model and feature are described below in conjunction with accompanying drawing, example is served only for explaining this practicality It is new, it is not intended to limit scope of the present utility model.

Embodiment 1

A in Fig. 1 and 1 in Fig. 3,2 and 4,5 corresponding, b is corresponding with 7, and c is corresponding with 3 and 6, and d is right with 1 ', 2 ' and 4 ', 5 ' Should, e is corresponding with 3 ' and 6 '.

In Fig. 2,2., 3. and 5. and 1. ' -6. ' draw-in groove being, can extract when less to institute's holding test tubes quantitative requirement Go out the transverse slat of 2,3 and No. 5 positions；The transverse slat of 2,3 and No. 5 positions is can be inserted into when holding test tubes quantity.In addition, in actual design In, this kind of rack for test tube can design in same layer position 2 rows and more than.

Should be noted when using：(1) if only placing individual layer test tube can meet use requirement, upper strata can have both been used, can have been used again Lower floor；(2) if placing two-layer test tube, advise first extracting out the 2nd and 3 layer of transverse slat, the 5th layer of transverse slat is placed into position, i.e., first places Lower floor's test tube, is then placed into position by the 2nd and 3 layer of transverse slat, then places upper strata test tube；(3) graduated cylinder is normally placed (base is downward) .

Preferred embodiments of the present utility model are the foregoing is only, it is all new in this practicality not to limit the utility model Within the spirit and principle of type, any modification made is equal to replacement, improvement etc., should be included in guarantor of the present utility model Within the scope of shield.
