Description
Technical field
The utility model belongs to the Design & preparation technical field of mould in Teenagers Popular Science Education, particularly a kind of teaching demonstration teaching aid prizing the earth.
Background technology
Archimedes says, " give me a fulcrum, I can prize the earth ".How lively each teenager is familiar to the words, show such scene to teenagers, inspires teenagers to explore natural interest.
Summary of the invention
The purpose of this utility model is: can design a kind of teaching aid, and what this teaching aid structurally can be lively annotates to teenager, and the well-known saying of Archimedes, excites teen-age aspiration to knowledge, reaches best education of science effect.
It is as follows that the utility model solves the problems of the technologies described above adopted technical scheme: impart knowledge to students with the demonstration teaching aid prizing the earth, comprise lever, module that cross section is isosceles triangle shape and earth mould, electromagnetic suspension apparatus is set below described module, the retroaction matched is set in module responds to steel plate with electromagnetic suspension apparatus; Described lever is arranged on a fulcrum of module, arranges earth mould in an end of lever; Under "on" position, the retroaction steel plate in module under electromagnetic suspension apparatus effect, can push away electromagnetic suspension apparatus, and module is suspended in the air.
The beneficial effects of the utility model: the utility model is more lively, life-like, and can play in teen-age education of science and technology well, impressive effect, can inspire the aspiration to knowledge of teenagers and the spirit of Science Explorations.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described.
Fig. 1 is main TV structure schematic diagram of the present utility model.
Embodiment
Embodiment 1 is imparted knowledge to students with the demonstration teaching aid prizing the earth, as shown in Figure 1, comprise lever 4, module 2 that cross section is isosceles triangle shape and earth mould, electromagnetic suspension apparatus 1 is set below described module 2, the retroaction to match is set in module 4 responds to steel plate 3 with electromagnetic suspension apparatus 1; Described lever 4 is arranged on a fulcrum of module 2, arranges earth mould 5 in an end of lever 4; Under "on" position, the retroaction steel plate 3 in module 2 under electromagnetic suspension apparatus 1 acts on, can push away electromagnetic suspension apparatus 1, module 2 is suspended in the air.
In practice, use the utility model, teenager can prize " earth " (comparatively light under magnetic levitation effect) in person, thus excites teen-age aspiration to knowledge, reaches well education and teaching efficiency simultaneously.Above-mentioned magnetic levitation system can bought on the market, has superconducting magnetic to suspend or the magnetic levitation of permanent magnetic material or the electromagnetic suspension apparatus of routine.
