The efficiency of teaching of teacher, thus affect the quality imparted knowledge to students it is difficult to meet the demand that teaching uses now.
Content of the invention
The purpose of this utility model is that provides a kind of higher mathematics epicycloid teaching aid to solve the above problems.
The utility model is achieved through the following technical solutions above-mentioned purpose：A kind of higher mathematics epicycloid teaching aid, including
Fixed circle, the first fixed circle, the second fixed circle, magnetic rings, fixed column, fixing groove, fixed handle, fixed body, dynamic circle, first dynamic round, the
Two dynamic circles, changes and fixing hole, described fixed circle includes the first fixed circle and second fixed to be justified, outside the described first fixed circle and the second fixed circle
Enclose and be equipped with magnetic rings, described first justifies inner ring surely is fixedly connected with fixed column, and the described second fixed circle is outer to be equipped with fixing groove, institute
State magnetic fixed body to be connected with the second fixed circle by fixed handle, described dynamic circle includes first and moves circle and the second dynamic circle, described bag
Include the first dynamic circle and the second dynamic circle periphery is equipped with magnetic rings, the described first dynamic circle inner ring is fixedly connected with fixed column, described the
Two dynamic circles are outer to be equipped with fixing groove, and described change is passed through fixed handle and is fixedly connected with the second dynamic circle, the described first dynamic circle and the
It is equipped with fixing hole outside two dynamic rounded edge.
Further, the magnetic rings in the magnetic rings and dynamic circle on described fixed circle are different in nature magnet ring.
Further, described fixing column bottom and fixing groove match.
Further, described fixed handle is cross fixed handle.
Further, described fixed body is magnetic fixed body.
The beneficial effects of the utility model are：This teaching aid structure is simple, easy to use, and will not go out during using
Now relative to sliding it is ensured that the accuracy of graphic plotting, and dynamic circle and determine circle and can be painted according to field research demand change size
Make cardiod and other figures, be easy to student and understand epicycloidal forming process and principle so that teaching and study are got up more
Plus easily, improve quality of instruction.
