Abstract
A kind of adjustable type rack for test tube, including upper backup pad, middle supporting plate and the lower supporting plate connected by connecting rod, multiple test tube through holes are set on upper backup pad and middle supporting plate；Upper backup pad intermediate region sets screwed hole, and connecting rod top sets the external screw thread corresponding with screwed hole；Bracing piece is set between middle supporting plate and lower supporting plate.Adjustable type rack for test tube provided by the utility model, height for fixing between the upper backup pad of test tube and middle supporting plate can be adjusted easily, connection between supporting plate and lower supporting plate during connecting rod can reinforce, prevent support plate edge from trembling or teetertottering the problem of causing test tube unstable.
Description
Technical field
The utility model belongs to experiment equipment field, and in particular to a kind of adjustable type rack for test tube.
Background technology
Rack for test tube is used to place the test tube for holding liquid in the lab, by the difference of held liquid volume, test tube
With multiple different length specifications, conventional has 10cm, 15cm, 20cm, 25cm etc., is obviously met not using same rack for test tube
Different length test tube demand.
In addition, many chemical experiments need to carry out under the conditions of heating or ice-water bath, such as sugared content is carried out using anthrone method
Continuous mode in, it is necessary to first boiling water bath then again ice-water bath cool down, general boiling water bath is to be placed in test tube in laboratory at present
In rack for test tube, be then placed in water-bath and carry out, and ice-water bath is because rack for test tube volume is larger, be put into water-bath need it is more
Ice cube, conventional method is to take out test tube from rack for test tube, is then placed directly within the beaker for hold frozen water and carries out, both compared
It is cumbersome, and test tube does not support in beaker, easily tilts, causes sample to be contaminated.
Utility model content
The purpose of this utility model is that provides a kind of adjustable type rack for test tube to solve the deficiencies in the prior art, adjustable
The height between rack for test tube supporting plate is saved, is adapted to the test tube of different length to use.
The purpose of this utility model is realized with following technical proposals：
A kind of adjustable type rack for test tube, including upper backup pad, middle supporting plate and the lower supporting plate connected by connecting rod, upper backup pad
With multiple test tube through holes are set in middle supporting plate；Upper backup pad intermediate region sets screwed hole, and connecting rod top sets corresponding with screwed hole
External screw thread；Bracing piece is set between middle supporting plate and lower supporting plate.
The rack for test tube also includes cup, and rib is set in cup upper inside wall；Upper backup pad is more than middle supporting plate and lower branch
Fagging, rib internal diameter are more than the external diameter of middle supporting plate and lower supporting plate, and less than the external diameter of upper backup pad, upper backup pad, middle branch
Fagging and lower supporting plate can be supported in cup by rib.
The small end sets handle.
The cup upper end sets overfall.
Adjustable type rack for test tube provided by the utility model, for fixing the height between the upper backup pad of test tube and middle supporting plate
Degree can be adjusted easily, connection between supporting plate and lower supporting plate during connecting rod can reinforce, prevent support plate edge from sending out
It is raw to tremble or the problem of causing test tube unstable of teetertottering.Therefore, adjustable type rack for test tube provided by the utility model, is available for not
Test tube with length uses.Moreover, the cup especially set is, it is necessary to when heating, can by by gripper shoe groups into support frame from cup
Taken out in body, support frame is put into water-bath and heated, it is necessary to when ice-water bath cools down, support frame can be put into cup
Row ice-water bath cools down.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model rack for test tube；
Fig. 2 is the structural representation of the utility model cup.
Embodiment
Adjustable type rack for test tube provided by the utility model, as shown in figure 1, including by upper backup pad 2, middle supporting plate 3 and under
The support frame that supporting plate 4 forms, is connected between upper backup pad 2, middle supporting plate 3 and lower supporting plate 4 by connecting rod 5；The He of upper backup pad 2
The corresponding test tube through hole 6 in multiple positions is set in middle supporting plate 3, test tube is led to by the test tube on upper backup pad 2 and middle supporting plate 3
Hole 6, the standing that can be consolidated will not run-off the straight phenomenon；The intermediate region of upper backup pad 2 sets screwed hole, and the top of connecting rod 5 is set and screw thread
The corresponding external screw thread 11 in hole；Can be by rotating upper backup pad 2, position of the regulation upper backup pad 2 on connecting rod 5, and then adjust
Upper backup pad and the distance of middle supporting plate, to adapt to the use of the test tube of different length.Middle supporting plate and lower supporting plate also can be with connecting
Bar is connected through a screw thread, and facilitates installation and dismounting between supporting plate and connecting rod.It is annular between middle supporting plate 3 and lower supporting plate 4
Bracing piece 12 is set, and bracing piece 12 is located at support plate edge, and preferably 2-4 is individual.Supporting plate and lower branch during connecting rod can reinforce
Connection between fagging, prevent support plate edge from trembling or teetertottering the problem of causing test tube unstable.
In order to make the experiment that support frame is conveniently used under heating and ice-water bath cooling condition, rack for test tube also includes cup
1, as shown in Fig. 2 setting rib 7 in the upper inside wall of cup 1, the upper backup pad size of support frame is more than middle supporting plate and lower support
Plate, the internal diameter of rib 7 are more than the external diameter of middle supporting plate 3 and lower supporting plate 4, and less than the external diameter of upper backup pad 2, so as to so that in
Supporting plate 3 and lower supporting plate 4 pass through rib, and upper backup pad 2 is supported on rib 7, therefore, can be quickly by test tube
Support frame and quickly connection and the separation of cup 1.Needing to heat in use, can be by test tube support frame quickly out of cup 1
Take out, be put into water-bath and heated, when needing ice-water bath to cool down, test tube support frame can be quickly placed in cup 1
Carry out ice-water bath cooling.Certainly, also test tube can be supported to be placed in cup 1 and carries out Heating Experiment.
Cup 1 and test tube support frame are preferably circular, compared to rectangle, can save space, place more test tubes；Connecting rod 5
Upper end can set handle 9, convenient to extract test tube support frame, and cup top can set lid, will using lid when carrying out ice-water bath cooling
Cup seals, and reduces the heat transfer of the inside and outside environment of cup.Cup upper end can set overfall 10, prevent cold in cup
But frozen water adds excessive, the problem of flooding test tube.
