Abstract
A kind of enclosed geometry body section apparatus for demonstrating, belongs to instruments used for education, is mainly made of cylindrical drum, positive square box, connecting tube, valve and fixed plate, it is characterized in that：Cylindrical drum is that closed container is made in 3mm transparent organic plastic plates by thickness with positive square box, then the hole to match with connecting tube is got at tin bottom of cylindrical drum and one bottom surface of positive square box, it is injected in the brine to positive square box with dyeing from hole with syringe, it is connected to by connecting tube between cylindrical drum and positive square box, with positive square box liquid level respectively as the section of cylinder and square, this apparatus for demonstrating is beneficial in that cylindrical drum liquid level：It to form closed system by being connected with connecting tube with two kinds of solids equipped with liquid and demonstrates the technology of geometry body section, while can see the different cross section feature of two kinds of solids.Simple structure, it is easy to operate, it is with obvious effects, the sectional view of demonstration solid can be facilitated.
Description
Technical field
It is related to demonstrating the section apparatus for demonstrating of solid, belongs to space geometry demonstration teaching aid field.
Background technology
In space geometry and Calculus Teaching, the understanding of sectional view is important one of content, cooperation teaching setting
Some demonstration teaching aids, such as a kind of solid section demonstration device are drilled although improving due to the use of same colored liquid section
Show and be still not easy to observe, and because the too small surface tension of liquid effect of device is obviously so that not smooth enough (its of liquid surface (section)
0009 section is mentioned：Liquid volume is not less than the 1/2 of solid container volume in syringe.Syringe maximum is 50 millis
Rise, that is, solid container volume is up to 100 milliliters, the square length of side is less than 5 centimetres), with syringe to container filling liquid
Injector push-rod (not fixed with syringe outer barrel) has certain position change with respect to outer barrel when body is demonstrated, while being also easy to make
Syringe falls off with the tubulature on container influences demonstration, how to be more convenient demonstration section, and this patent will solve the problems, such as this.

Invention content
A kind of enclosed geometry body section apparatus for demonstrating under classroom or class is solved, emphatically by with connecting tube and dress
There are two kinds of solids of liquid to be connected, to demonstrate the technology of geometry body section.
Technical solution：A kind of enclosed geometry body section apparatus for demonstrating, mainly by cylindrical drum, positive square box, connecting tube,
Valve and fixed plate are constituted, it is characterized in that：Cylindrical drum is made of thickness for 3mm transparent organic plastic plates closed with positive square box
Then container gets the hole to match with connecting tube in tin bottom of cylindrical drum and one bottom surface of positive square box, with syringe from
In brine to positive square box (or cylindrical drum) of the hole injection with dyeing, total injection is positive square box (or cylindrical drum) interior space
Volume half, the both ends connecting tube a and connecting tube b are respectively fixed on cylindrical drum and are sealed on the hole edge of positive square box,
It is exactly to be connected to by connecting tube between cylindrical drum and positive square box, by valve control, (two connect connecting tube a with connecting tube b
The valve of pipe opens and closes simultaneously, realize a working fluid, another moving air, avoid only there are one connecting tube when because
Liquid inlet container internal pressure increases the directed flow problem for influencing liquid), cylindrical drum is fixed on one with positive square box by fixed plate
It rises (polylith fixed plate can be fixed as needed, keep device firm, be hardly damaged)；The diameter of the cylindrical drum and positive square box
The length of side it is equal, the length of side of positive square box is 15cm~20cm, and cylindrical drum is identical as the volume of positive square box；Space in cylindrical drum
As cylinder, square cassette interior space is as square；Cylindrical drum liquid level is with positive square box liquid level respectively as cylinder
With the section of square.
When demonstration, open valve control brine from a container flow into another container it is a certain amount of after, close valve, both hands
It holds fixed plate and slowly changes container lean angle, so that it may be exactly demonstration circle to see cylindrical drum liquid level and positive square box liquid level
The sectional view of cylinder and square in corresponding position.
The usefulness of this apparatus for demonstrating, by (being flowed convenient for liquid with two connecting tubes, not having to bibliography《One
Kind solid section demonstration device》Air hole is beaten on container, is beaten air hole misoperation and is easy leakage body) and equipped with liquid
Two kinds of solids are connected to form closed system to demonstrate the technology of geometry body section, while can see two kinds of solids not
With section feature.Simple structure, at low cost, easy to operate, demonstrating effect is apparent, and the global sections figure for being easily formed solid is general
It reads, the method can also be generalized to the demonstration of the object section figure of other shapes, this experimental design, which is more advantageous to, promotes student
Initiative spirit and the ability of practice culture.
