Description
Technical field
The present invention relates to a kind of chemical experiment demonstration test tube, belong to teaching equipment field.
Background technology
Test tube, the instrument that chemical laboratory is conventional, serve as the reaction vessel of a small amount of reagent, when room temperature or heating, (should preheat before heating, not so test tube easily bursts.) use.Test tube divides common test tube, tool test tube, centrifuge tube etc. multiple.In teaching demonstration is tested, test tube is generally used for the chemical reaction after demonstrating two kinds of liquid mixing, but the general small volume of existing test tube, observation of students inconvenience at a distance.If adding the volume of Boiling tube, then need the amount of fluid of filling also to increase, add the cost of lecture experiment.
Summary of the invention
The deficiency existed for prior art, the technical problem to be solved is to provide a kind of chemical experiment demonstration test tube, easy to use, facilitates observing response process.
For solving above-mentioned technical problem, the present invention adopts the technical scheme that, a kind of chemical experiment demonstration test tube, including test tube body, the top of test tube body is provided with a sealing plug, and sealing plug is provided with two filler pipes；Described test tube body includes a cylindrical glass tubing, and glass tubing bottom is arc bottom, and the radian of arc bottom is 2.14；Described glass tubing includes front glass face and rear end glass surface, the sidewall docking of front glass face and rear end glass surface；The cross section of described rear end glass surface is semicircle；The cross section of the outer surface of described rear end glass surface is semicircle, and the cross section of the inner surface of rear end glass surface is arc, and the radian of the cross section of the inner surface of rear end glass surface is 3.02；Be provided with arc-shaped protrusions on the inner surface of described rear end glass surface, arc-shaped protrusions radian be 2.25；Being provided with dividing plate between described front glass face and rear end glass surface, dividing plate is provided with some permeability holes being uniformly arranged, two filler pipes are respectively arranged at the both sides of dividing plate.
Optimizing, above-mentioned chemical experiment demonstration test tube, the top of described filler pipe is provided with rubber extruded capsule.
It is an advantage of the current invention that it can overcome the drawback of prior art, reasonable in design is novel.Glass tubing is divided in the design of the application front glass face and rear end glass surface, and rear end glass surface maintains the shape invariance of glass tubing cylindrical in prior art, front glass face is set to the shape that inside and outside end face radian is different, serves the effect of convex lens.If the inside and outside end face radian difference in front glass face is excessive, manufacture difficulty can be improved, increase manufacturing cost.Therefore the radian of surfaces externally and internally is set to 3.02 and 2.25, although such radian difference is simple to manufacture, but amplification effect is not enough, owing to, in the technical scheme of above-mentioned situation the application, arranging arc-shaped protrusions on the inner surface of rear end glass surface, increases amplification effect.Also liquid can be made to be sufficiently mixed in use be not required to rock, the technical scheme of the application adds dividing plate and some permeability holes are set on dividing plate, so two parts liquid is interpenetrated mixing by permeability hole, to reach to mix sufficient effect, further facilitates observing response effect.

In figure: 1 be sealing plug, 2 be filler pipe, 3 be arc bottom, 4 be front glass face, 5 be rear end glass surface, 6 be arc-shaped protrusions, 7 be dividing plate, 8 be permeability hole, 9 for rubber extruded capsule.
Detailed description of the invention
The technical characterstic of the present invention is expanded on further below in conjunction with the accompanying drawings with specific embodiment.
The present invention is a kind of chemical experiment demonstration test tube, and including test tube body, the top of test tube body is provided with a sealing plug, and sealing plug is provided with two filler pipes；Described test tube body includes a cylindrical glass tubing, and glass tubing bottom is arc bottom, and the radian of arc bottom is 2.14；Described glass tubing includes front glass face and rear end glass surface, the sidewall docking of front glass face and rear end glass surface；The cross section of described rear end glass surface is semicircle；The cross section of the outer surface of described rear end glass surface is semicircle, and the cross section of the inner surface of rear end glass surface is arc, and the radian of the cross section of the inner surface of rear end glass surface is 3.02；Be provided with arc-shaped protrusions on the inner surface of described rear end glass surface, arc-shaped protrusions radian be 2.25；Being provided with dividing plate between described front glass face and rear end glass surface, dividing plate is provided with some permeability holes being uniformly arranged, two filler pipes are respectively arranged at the both sides of dividing plate.The top of described filler pipe is provided with rubber extruded capsule.
It is an advantage of the current invention that it can overcome the drawback of prior art, reasonable in design is novel.Glass tubing is divided in the design of the application front glass face and rear end glass surface, and rear end glass surface maintains the shape invariance of glass tubing cylindrical in prior art, front glass face is set to the shape that inside and outside end face radian is different, serves the effect of convex lens.If the inside and outside end face radian difference in front glass face is excessive, manufacture difficulty can be improved, increase manufacturing cost.Therefore the radian of surfaces externally and internally is set to 3.02 and 2.25, although such radian difference is simple to manufacture, but amplification effect is not enough, owing to, in the technical scheme of above-mentioned situation the application, arranging arc-shaped protrusions on the inner surface of rear end glass surface, increases amplification effect.Also liquid can be made to be sufficiently mixed in use be not required to rock, the technical scheme of the application adds dividing plate and some permeability holes are set on dividing plate, so two parts liquid is interpenetrated mixing by permeability hole, to reach to mix sufficient effect, further facilitates observing response effect.
Certainly, described above is not limitation of the present invention, and the present invention is also not limited to the example above, those skilled in the art, in the essential scope of the present invention, the change made, retrofits, adds or replaces, all should belong to protection scope of the present invention.
