Abstract

The utility model discloses a conjoined test tube which comprises a test tube body, wherein the side wall of the test tube body is provided with two splicing elements which are axisymmetric with respect to the central axis of the test tube body; one of the two splicing elements is a socket element, and the other is an insertion and clamping element; the socket element is provided with a vertical T-shaped clamping groove; the clamping groove penetrates through the upper end surface of the socket element; and the insertion and clamping element is in a T-shaped structure which is matched with the clamping groove in a sliding and clamping connection manner. According to the utility model, the side wall of the test tube body is provided with the socket element and the insertion and clamping element which are matched with each other in a clamping connection manner, so that solutions of two contrast experiment substances can be respectively filled into the two test tubes in the use process, and then, the insertion and clamping element of one test tube can be inserted into the socket element of the other test tube, thereby ensuring that the two substances can be conveniently contrasted by using the conjoined test tube which does not need to be held by a user with two hands. Thus, the contrast is enhanced, the convenience is brought to teaching, and the teaching efficiency is improved.

Description

The disjunctor test tube

Technical field

The utility model belongs to the chemical apparatuses field, is specifically related to a kind of disjunctor test tube.

Background technology

When biological or chemical is imparted knowledge to students, the contrast experiment who often uses two kinds of physical properties, this just needs to prepare two test tubes does respectively, when showing experimental result to the student, needs two hands to grasp respectively a test tube, very inconvenient.

Summary of the invention

Technical problem to be solved in the utility model is for above-mentioned the deficiencies in the prior art, and a kind of disjunctor test tube is provided, and it need to make the trouble that with the hands grasps respectively test tube in the time of can solving biology, chemical contrast experiment.

The technical scheme that the utility model adopts is: a kind of disjunctor test tube, comprise the test tube body, the sidewall of described test tube body is provided with two with respect to the axisymmetric plug connector in the axis of this test tube body, wherein a plug connector is socket piece, another plug connector is plug-in card spare, described socket piece is provided with vertical T font draw-in groove, and this draw-in groove runs through the upper surface of this socket piece, and described plug-in card spare is the T character form structure that cooperates with this draw-in groove slip clamping.

As preferably, the degree of depth of described draw-in groove is consistent with the height of described plug-in card spare.

As preferably, described socket piece and plug-in card spare and described test tube body by integral forming.

The beneficial effects of the utility model are: because the utility model is provided with socket piece and the plug-in card spare that mutual clamping cooperates at the test tube body sidewall, during use, the solution of two kinds of contrast experiment's materials is added to respectively two in vitro, and then wherein the plug-in card spare of a test tube inserts in the socket piece of another test tube, so that test tube of the present utility model can conveniently contrast two kinds of materials, need not the user with the hands hold, both strengthened contrast, bring convenience to teaching again, improve efficiency of teaching.

Description of drawings

Fig. 1 is the utility model structural representation;

Fig. 2 is A-A cutaway view among Fig. 1.

Among the figure: 1, test tube body; 2, socket piece; 3, plug-in card spare; 4, draw-in groove.

The specific embodiment

Below in conjunction with the accompanying drawings and the specific embodiments the utility model is described in further detail.

As depicted in figs. 1 and 2, a kind of disjunctor test tube, comprise test tube body 1, the sidewall of described test tube body 1 is provided with two with respect to the axisymmetric plug connector in the axis of this test tube body 1, wherein a plug connector is socket piece 2, another plug connector is plug-in card spare 3, described socket piece 2 and plug-in card spare 3 and described test tube body 1 are one-body molded, described socket piece 2 is provided with vertical T font draw-in groove 4, this draw-in groove 4 runs through the upper surface of this socket piece 2, described plug-in card spare 3 is the T character form structure that cooperates with the 4 slip clampings of this draw-in groove, and the degree of depth of described draw-in groove 4 is consistent with the height of described plug-in card spare 3.

Because the utility model is provided with socket piece 2 and the plug-in card spare 3 that mutual clamping cooperates at test tube body 1 sidewall, during use, the solution of two kinds of contrast experiment's materials is added to respectively two in vitro, and then wherein the plug-in card spare 3 of a test tube inserts in the socket piece 2 of another test tube, so that test tube of the present utility model can conveniently contrast two kinds of materials, need not the user with the hands hold, both strengthened contrast, bring convenience to teaching again, improve efficiency of teaching.

The above, it only is the utility model preferred embodiment, so can not limit the scope that the utility model is implemented with this, the equivalence of namely doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model patent contains.
