Description

[Detailed explanation of the invention] This invention relates to a chemical experiment tool stand for test tubes, reagent bottles, droppers, stirring rods, etc. It must be possible to stand the test tubes and reagent bottles upright safely, and the test tubes and reagent bottles placed upright must be visible from the front to the bottom of the stand, and the chemical experiment tools that have been placed upright must be removed and removed from the stand. To make it possible to conveniently use the reagent tray for stirring and mixing reagents, etc. by turning the whole thing upside down, and to be able to provide it at a low price with a simple structure that can be integrally formed by plastic molding, etc. The purpose is to allow multiple experimental utensil stands to be used even if they are connected horizontally.

Hereinafter, the structure of the chemical experiment tool stand of this invention will be described in detail with reference to the drawings. In the drawing, 1 is an oblong base having a recessed space 2 whose lower side is open, and this front and rear inclined surface 1a, lb A plurality of projecting plate parts 3 (for example, 6 pieces) are integrally protruded from the flat upper surface 1C connected to the test tube A and the reagent bottle B with a horizontal interval corresponding to the size of the test tube A and the reagent bottle B, and each projecting plate part An arcuate surface 4 for fitting the test tube A and the reagent bottle B is provided on the opposite side surface of the tube.

5 and 6 are a pair of projecting plate portions 3a located on the left side in the figure. 3b, two large and small bottomed holes are opened in the upper surface of the base part 1, and a stirring rod C with a spoon is set up in the larger diameter bottomed hole 5 as shown in FIG. Further, a dropper D is placed in the bottomed hole 6 of the smaller diameter as shown in FIG.

Reference numeral 7 designates a plurality of (for example, three) spherical recessed dishes that are integrally molded in the upper space 2a of the recessed space 2 in the base part 1. It is used as a reagent dish when placed upside down so that it is touching the floor.

The projecting plate part 3f located at the right end in the drawing of the projecting plate part 3 has its side end surface 3f' flush with the end surface If' of the base part 1, and its both end surfaces 3f' and 1f' On the formed vertical end face F, dovetail grooves 8 and dovetail groove engagement protrusions 9 for horizontally connecting two experimental utensil stands are provided vertically and distributed symmetrically with respect to the center vertical line.

Therefore, reverse the left and right ends of one experiment utensil holder against the other, and match them as shown by the imaginary lines in Figure 4, and insert the dovetail groove 8 and the dovetail groove engagement protrusion 9 from above and engage them. In this case, two experimental odor senses can be easily connected horizontally.

Since the chemical experiment olfactory sense of this invention has the above-mentioned structure, it has the following effects.

(1) A plurality of protruding plate parts 3 are provided on the upper surface of the base part 1 at horizontal intervals corresponding to the sizes of the test tubes A and reagent bottles B, and test tubes A and reagents are provided on the opposite side of each protruding plate part. In addition to forming an arcuate surface 4 for fitting the bottle B, a bottomed hole is provided on the upper surface of the base portion 1 between at least a pair of opposing protruding plates to accommodate a stirring frame C, etc. Chemical experiment tools such as A, reagent bottle B, dropper D, and stirring frame C can be safely stood up, and test tube A and reagent bottle B can be seen through from the front of the stand to the bottom, making it easy to carry out tests. The experimental status in tube A, the amount of chemical solution remaining in reagent bottle B, etc. can be easily seen, making it convenient to use.

(2) The base part 1 has a recessed cavity 2 whose lower side is open, and several spherical recesses 7 are provided on the upper wall part 2a of the recessed cavity. However, if you remove the experimental tools such as test tubes A and reagent bottles B, and install the entire experiment odor detector upside down so that each projecting plate part 3 is in contact with the floor, the recessed dish 7
comes out on the top surface and can be conveniently used as a reagent container for stirring and mixing reagents, etc.

(3) The experimental olfactory sensor of this invention has a simple structure that can be integrally molded using plastic molding or the like, so it can be provided at a low price.

(4) If the dovetail groove 8 and the dovetail groove engagement protrusion 9 are provided on the vertical end face F of one end of the experimental scent detector as in this embodiment, a plurality of experimental scent detectors can be used by connecting them horizontally. Even if a single experimental smelling device is relatively small, a large experimental smelling device can be constructed by connecting a plurality of them to accommodate many experimental tools.
