Abstract
The invention discloses a test tube support for class presentation. The test tube support comprises a base. A support rod is arranged on the base. A support bar is arranged on the center of the support rod. The support bar is perpendicular to the support rod. The top end of the support bar is provided with a test tube bracket, the test tube bracket comprises a central support ring, the upper part of the central support ring is provided with a test tube base, which is in a hollow tube shape; the lower part of the central support ring is provided with a heating cover, which is in a conical shape; the conicity of the heating cover is 1:2.25; the test tube base comprises a front glass surface and a rear glass surface, and the lateral walls of the front glass surface and the rear glass surface are butt-jointed. The test tube support can overcome the shortages of prior art, and the structural design is reasonable and novel.
Description
Technical field
The present invention relates to a kind of class demonstration test tube support, 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 class demonstration test tube support, easy to use, facilitates observing response process.
For solving above-mentioned technical problem, the present invention adopts the technical scheme that, a kind of class demonstration test tube support, including base, base being provided with a support bar, the middle part of support bar is provided with a cradling piece, cradling piece is vertically arranged with support bar, and the top of cradling piece is provided with test tube support；Described test tube support includes that a midfoot support ring, midfoot support ring top are provided with test tube flat, and test tube flat is hollow tubular, and midfoot support ring bottom is provided with heating mantles；Described heating mantles is cone-shaped hood, and the tapering of heating mantles is 1:2.25；Described test tube flat 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 2.94；The lower end of described test tube flat is provided with horizontal ends.
Optimize, above-mentioned class demonstration test tube support, described horizontal ends is provided with through hole.
It is an advantage of the current invention that it can overcome the drawback of prior art, reasonable in design is novel.Test tube flat is divided into front glass face and rear end glass surface by the design of the application, rear end glass surface maintains the shape invariance of the cylindrical glass tubing of test tube commonly used in the 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.In order to accelerate firing rate, the design of the application arranges heating mantles in midfoot support ring bottom, the heat of ethanol is gathered with in heating mantles, prevent heat to scatter and disappear.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the A-A sectional structure schematic diagram of Fig. 1；
Fig. 3 is the structural representation of the heating mantles of the present invention；
In figure: 1 be base, 2 be support bar, 3 be cradling piece, 4 be midfoot support ring, 5 be heating mantles, 6 be front glass face, 7 be rear end glass surface, 8 be horizontal ends, 9 be through hole, 10 for test tube flat.
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 class demonstration test tube support, including base, base is provided with a support bar, and the middle part of support bar is provided with a cradling piece, and cradling piece is vertically arranged with support bar, and the top of cradling piece is provided with test tube support；Described test tube support includes that a midfoot support ring, midfoot support ring top are provided with test tube flat, and test tube flat is hollow tubular, and midfoot support ring bottom is provided with heating mantles；Described heating mantles is cone-shaped hood, and the tapering of heating mantles is 1:2.25；Described test tube flat 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 2.94；The lower end of described test tube flat is provided with horizontal ends.It is provided with through hole in described horizontal ends.
It is an advantage of the current invention that it can overcome the drawback of prior art, reasonable in design is novel.Test tube flat is divided into front glass face and rear end glass surface by the design of the application, rear end glass surface maintains the shape invariance of the cylindrical glass tubing of test tube commonly used in the 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.In order to accelerate firing rate, the design of the application arranges heating mantles in midfoot support ring bottom, the heat of ethanol is gathered with in heating mantles, prevent heat to scatter and disappear.
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.
