Abstract

The utility model belongs to a novel multifunctional teaching experiment rack for students to use in experiment classes. The novel multifunctional teaching experiment rack has simple structure, complete functions and convenience in use, and can effectively prevent contamination. The novel multifunctional teaching experiment rack made of high-hardness transparent plastics comprises a column 1, a bracket 2 and a bottom slot 3, wherein the column 1 takes the shape of a long cylinder and is positioned on one side of the experiment rack for test tubes to get inverted for airing; the bracket 2 is positioned on the other side of the experiment rack, and insertion holes 4 with different calibers are formed on the bracket 2 for placing test tubes, suction tubes and droppers with different calibers; and the bottom slot 3 taking the shape of a cuboid is formed at the bottom of the experiment rack for accommodating liquid from the test tubes, the suction tubes, and the droppers.

Description

Multifunction education experiment frame

Technical field:

The utility model belongs to a kind of doing for the student and places the new teaching instrument that test tube uses that dries when testing.

Background technology:

The student often needs to use experimental tools such as test tube, suction pipe, dropper in the laboratory of courses such as chemistry, biology.Test tube then needs to be placed on and carries out chemical reaction on the experiment frame in the experimentation.Experiment finishes, and scrubs will be placed on the experiment frame after finishing and dries, and uses for continuing.And employed experiment frame on the present laboratory, function singleness can only be placed test tube, can not place experimental tools such as suction pipe, dropper; Test tube after scrubbing, dropper, the residual liquid of suction pipe flow on the laboratory table easily, pollute desktop; Residual liquid was stayed when the test tube after scrubbing was just being put in vitro influences subsequent experimental easily, and test tube mouth easily weares and teares when putting upside down.Present experiment frame can not satisfy the needs of modern experiment teaching.

Summary of the invention:

Main task of the present utility model be for use student experimenting class hour a kind of simple in structure, multiple functional, easy to use can effective antipollution Multifunction education experiment frame.

The utility model is achieved in that it makes with the high-hard, transparent plastics, is made up of column, support and kerve three parts.Column is oval column, is positioned at a side of experiment frame, is inverted when drying for test tube and uses; Support is positioned at the opposite side of experiment frame, and the jack of different bores is arranged above, can place test tube, suction pipe, the dropper of different bores; Kerve is positioned at the bottom of experiment frame, is rectangular structure, can hold the liquid that flows out in test tube, suction pipe, the dropper.

Advantage of the present utility model is: simple in structure, multiple functional, easy to use, can place test tube, suction pipe, the dropper of different bores; The kerve design can effectively prevent the pollution of chemical reagent; The huge market demand, production cost is low, is convenient to marketing.

Description of drawings:

Fig. 1 is a structural representation of the present utility model.

Among Fig. 1, the 1st, column, the 2nd, support, the 3rd, kerve, the 4th, jack.

The specific embodiment:

In conjunction with the accompanying drawings embodiment of the present utility model is described further: during experiment, test tube, suction pipe, dropper can be placed in the jack 4 of support 2 different bores.After test-tube brush is clean, can be upside down on the column 1 and dries naturally.The liquid that test tube, suction pipe, dropper spill flows in the kerve 3, outwells together at last, prevents to pollute experimental bench.

Claims (1)

1. Multifunction education experiment frame, it is characterized in that: it is made with the high-hard, transparent plastics, form by column (1), support (2) and kerve (3) three parts, column (1) is oval column, be positioned at a side of experiment frame, support (2) is positioned at the opposite side of experiment frame, and the jack (4) of different bores is arranged above, kerve (3) is positioned at the bottom of experiment frame, is rectangular structure.
