Abstract
The utility model relates to a novel test tube rack. The novel test tube rack comprises a base (1), a rack body (2) and a plurality of test tube holes (3), wherein the test tube holes (3) are formed in the rack body (2), a vertical backing board (4) is arranged at the rear sides of the base (1) and rack body (2), a horizontal through slot (5) is formed in the rear side of each test tube hole (3), a plurality of insertion grooves (6) in upward-downward correspondence to the through slots (5) are formed in the rear side of the upper surface of the base (1), and background boards (7) are inserted into the through slots (5) and the insertion grooves (6). The novel test tube rack is provided with the backing board and the background boards, and the background boards are in movable insertion connection with the test tube rack through the through slots and the insertion grooves, so that experimental phenomena in test tubes can be set off by replacing background boards of different colors according to the needs of experiments, then, the interference caused by ambient light is alleviated, the experimental observation effect is enhanced, and the observation distance is enlarged.
Description
Technical field
The utility model relates to a kind of experimental apparatus, particularly a kind of rack for test tube.
Background technology
When doing chemical experiment, often will use rack for test tube, but traditional rack for test tube is simple in structure, only has and place and the effect of firm test tube, and without the effect of Enhancement test observing effect, be therefore not easy to the observation of more remote classmate when doing lecture experiment.
Summary of the invention
The technical problems to be solved in the utility model is: overcome the deficiency of traditional rack for test tube, a kind of Enhancement test observing effect is provided, conveniently do the test tube stand of lecture experiment.
For realizing above-mentioned technical problem, the utility model adopts following technical scheme:
A kind of test tube stand, comprise base, support body and test tube hole, on support body, be provided with a plurality of test tubes hole, the rear side of base and support body is provided with a vertical liner plate, rear side in each test tube hole is provided with a horizontal through slot, rear side at base upper surface is provided with a plurality of slots upper and lower corresponding with through slot, in through slot and slot, is inserted with background board.
Adopt after such scheme, the beneficial effects of the utility model are:
Because this test tube stand is provided with liner plate and background board, background board is plugged in together by through slot and slot and rack for test tube activity, therefore can set off invisible spectro experimental phenomena by the experimental background board that need to change different colours, thereby alleviate the interference of ambient light, Enhancement test observing effect, strengthens viewing distance.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Accompanying drawing 1 is the surface structure schematic diagram of an embodiment of this test tube stand.
The specific embodiment
As shown in Figure 1: a kind of test tube stand, comprise base 1, support body 2 and test tube hole 3, on support body 2, be provided with a plurality of test tubes hole 3, the rear side of base 1 and support body 2 is provided with a vertical liner plate 4, rear side in each test tube hole 3 is provided with a horizontal through slot 5, at the rear side of base 1 upper surface, be provided with a plurality of and through slot corresponding slot 6 Shang Xia 5, in through slot 5 and slot 6, be inserted with background board 7.
In using the process of this test tube stand, when shelving and store test tube, test tube is put in rack for test tube from test tube hole 3, and when needs are observed invisible spectro reacting phenomenon, according to the invisible spectro color phenomenon that is about to occur, the background board 7 of respective color is injected in corresponding through slot 5 and slot 6, under the setting off of background board 7, invisible spectro reacting phenomenon will be more obvious like this, thereby facilitate observer's observation.
Claims (1)
1. a test tube stand, comprise base (1), support body (2) and test tube hole (3), on support body (2), be provided with a plurality of test tubes hole (3), it is characterized in that: the rear side of base (1) and support body (2) is provided with a vertical liner plate (4), rear side in each test tube hole (3) is provided with a horizontal through slot (5), rear side at base (1) upper surface is provided with a plurality of slots (6) upper and lower corresponding with through slot (5), in through slot (5) and slot (6), is inserted with background board (7).
