Abstract
The utility model relates to the teaching aid field and particularly discloses a three-dimensional stereo graphic demonstration device. The demonstration device adopts the scheme that a plurality of stereo graphic outer contour frameworks are made of metal wires; each stereo graphic outer contour framework is wound with a luminous wire; and the luminous wires are connected with a power supply through a switch. When the switch is turned on, the luminous wires define the stereo graphic outer contour frameworks, so that students can observe straightforwardly, temporary assembly in a class is not needed, the use is convenient, and certain popularization significance is realized.
Description
Technical field
The utility model relates to a kind of teaching aid, is specially a kind of three-dimensional graph apparatus for demonstrating.
Background technology
When three-dimensional picture was resolved teaching, because solid figure is more abstract, the student was difficult to understand relevant knowledge.Intuitive when imparting knowledge to students for improving, allow student's fast understanding, usually need simulate solid figure by the three-dimensional graph apparatus for demonstrating, present three-dimensional graph apparatus for demonstrating normally adopts the mode of piecing together to use some widgets to form a plurality of three-dimensional picture, when using, this apparatus for demonstrating needs interim assembling, operate cumbersomely, and cost of manufacture is higher, has brought inconvenience to teaching.
The utility model content
For overcoming above-mentioned technical matters, the utility model provides a kind of easy to use, with low cost, three-dimensional graph apparatus for demonstrating that teaching efficiency is good.
For realizing above-mentioned technical purpose, the utility model is realized by the following technical solutions: a kind of three-dimensional graph apparatus for demonstrating, comprise some solid figure outline frameworks of making by tinsel, it is characterized in that: the outline framework of each solid figure all twines a luminous filament, and luminous filament connects power supply by switch.
The utility model is compared with conventional art, has following beneficial effect: when switch connection, luminous filament sends radiance, luminous filament presents the outline framework of the solid figure at place, so that allow the student watch intuitively, because the outline framework is made in advance, last class hour need not interim assembling, use more conveniently, cost is lower, has certain dissemination.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is outline framework and luminous filament unitized construction synoptic diagram.
Among the figure, 1, right cylinder, 2, cone, 3, rectangular parallelepiped, 4, high index line, 5, the radius index line, 6, luminous filament, 7, switch, 8, power supply.
Embodiment
Referring to accompanying drawing 1,2, a kind of three-dimensional graph apparatus for demonstrating, comprise some solid figure outline frameworks of making by tinsel, described solid figure such as right cylinder 1, cone 2, rectangular parallelepiped 3, the outline framework of each solid figure all twines a luminous filament 6, luminous filament 6 connects power supplys 8 by switch 7, also can make the parameter line of solid figure such as right cylinder 1, the high index line 4 of cone 2, radius index line 5 by tinsel simultaneously.
Claims (1)
1. a three-dimensional graph apparatus for demonstrating comprises some solid figure outline frameworks of being made by tinsel, and it is characterized in that: the outline framework of each solid figure all twines a luminous filament, and luminous filament connects power supply by switch.
