Abstract
The utility model discloses a can demonstrate teaching device of volume conversion belongs to the mathematics field, and its structure includes: square body container, look liquid window, inflater, stopper, connecting pipe, a cylinder section of thick bamboo lose heart, square body container is the cavity structures of interior sky, the square preceding middle part of body container is equipped with looks the liquid window, looking the liquid window and constituting for glass, look liquid window side along being equipped with the scale, square body container top is equipped with the apron structure, apron structure middle part is equipped with the inflater, and the apron lateral part is equipped with the circular through -hole that holds the stopper that loses heart, and square body container side bottom is equipped with the connecting pipe, the connecting pipe other end is connected with cylinder bobbin base portion. The utility model discloses simple structure can make things convenient for the conversion between the square body of realization directly perceived and the cylinder volume, can conveniently read the volume numerical value that both correspond with the help of scale between them in addition.
Description
Technical field
The utility model relates to a kind of instructional device demonstrating volume conversion, belongs to art of mathematics.
Background technology
Volume, geometry technical term is the amount that object occupies how many spaces.The International System of Units of volume is cubic meter.The volume of a solid articles is that a numerical value is in order to describe the space that this object occupies at three dimensions.One-dimensional space object (as line) and two-dimensional space object (as square) are all zero volume in three dimensions.
Volume conversion between current different solid is content very important in middle-school mathematics teaching.
Utility model content
The utility model, for the needs of solid volume change teaching in current Junior Mathematics, devises a kind of instructional device demonstrating volume conversion.
The technical scheme in the invention for solving the technical problem is:
This is a kind of can demonstrate instructional device of volume conversion, and its structure comprises: square container, look liquid window, inflator, lose heart plug, connecting pipe, cylindrical drum; Square container is the cavity body structure of interior sky, described square container forward, central part is provided with looks liquid window, described is that glass is formed depending on liquid window, scale is provided with depending on liquid reveal edge, square container top is provided with covering plate structure, is provided with inflator in the middle part of described covering plate structure, and cover plate sidepiece is provided with the manhole holding the plug that loses heart, square container side bottom is provided with connecting pipe, and the described connecting pipe other end is connected with bottom cylindrical drum.
The described cylindrical drum surface of revolution is axially arranged with scale.
Described cylindrical drum cylindrical shell is that clear glass is formed, and cylindrical drum top is hatch frame.
Compared with prior art, the beneficial effects of the utility model are:
The utility model structure is simple, can facilitate the conversion intuitively realized between square body and cylinder volume, in addition can by both scales, the volumetric quantities that convenient both readings are corresponding.
Accompanying drawing explanation
Fig. 1 is the utility model one-piece construction figure.
In figure: 1 square container, 2 looks liquid window, 3 inflators, 4 lose heart plug, 5 connecting pipes, 6 cylindrical drum.
Embodiment
As shown in Figure 1: a kind of can demonstrate volume conversion instructional device, its structure comprises: square container 1, look liquid window 2, inflator 3, lose heart plug 4, connecting pipe 5, cylindrical drum 6; Square container 1 is the cavity body structure of interior sky, described square container 1 forward, central part is provided with looks liquid window 2, described liquid window 2 of looking is for glass formation, depending on liquid window 2 side along being provided with scale, square container 1 top is provided with covering plate structure, is provided with inflator 3 in the middle part of described covering plate structure, and cover plate sidepiece is provided with the manhole holding the plug 4 that loses heart, square container 1 side bottom is provided with connecting pipe 5, and described connecting pipe 5 other end is connected with bottom cylindrical drum 6; Described cylindrical drum 6 surface of revolution is axially arranged with scale; Described cylindrical drum 6 cylindrical shell is that clear glass is formed, and cylindrical drum 6 top is hatch frame.
A kind of instructional device demonstrating volume conversion described by the present embodiment, to annotate in square container 1 during use certain water gaging, capping is sealed, disappointing plug 4 is installed, then utilize inflator 3 toward gas injection in square container 1, water flows through connecting pipe 5 and enters cylindrical drum 6 under gas pressure, the variable quantity of water reads by the scale in square container 1 cylindrical drum 6 by this process, this process can by can direct vision depending on liquid window 2 and cylindrical drum 6 itself, different solid volume transformational relation can be obtained, the utility model structure is simple, the conversion intuitively realized between square body and cylinder volume can be facilitated, in addition can by both scales, the volumetric quantities that convenient both readings are corresponding.
The above, be only embodiment of the present utility model, and those of ordinary skill in the art are in the scope that the utility model discloses, and the change that can expect easily, within the protection domain that all should be encompassed in utility model.
