The utility model has the advantages of reasonable design, operation convenient to use has realized the measurement operation who makes graphic operation and angle of straight line, fibonacci arc and circular, circular arc through setting up ruler, semicircle calibrated scale and compasses very much, the angle of measuring plane figure that can be convenient, and the required angle of drawing that can also be convenient provides convenient for the mathematical education.
Description
Technical field
The utility model relates to a kind of Multifunction mathematics teaching aid device.
Background technology
Class hour in instructors, in order to the content of course can be told about more intuitively, it is all use some teaching aids, when especially carrying out several teaching or mathematics teaching, usually to be used ruler, set square and compasses, and at present, these teaching aids are independent individuality, the different graphic needing teacher to draw as required during use takes different teaching aids repeatedly, such as when drawing specific angle, teacher needs the one side first drawing angle with ruler usually, utilize angulation tolerance to go out the angle needed afterwards to make a mark, recycle ruler afterwards and complete mapping, complex steps, operation inconvenience, existing drawing tool does not possess measurement function simultaneously, can not the angle of measurement pattern, existing teaching aid uses extremely inconvenience in a word.
Practical novel content
The technical problems to be solved in the utility model is to provide the Multifunction mathematics teaching aid device that a kind of structure is simple, easy to operate, security is high.
For solving the problem, the utility model adopts following technical scheme:
A kind of Multifunction mathematics teaching aid device, comprise base, semicircle scaleplate, transparent panel, universal stage, lever, compasses leg, slide scale, graphical boxes and compasses pin, described base back surface is provided with magnet, described base and semicircle scaleplate Integral design are shaping, described base is provided with universal stage, described universal stage is connected with lever by hinged axle, described lever is connected with compasses leg by hinged axle, described compasses leg top is provided with compasses pin, described compasses leg is provided with slide scale, described semicircle scaleplate is provided with transparent panel, described transparent panel is provided with graphical boxes, described base is provided with chi groove, it is provided with flexible chi in described chi groove, described compasses leg is provided with scale marks.
As preferably, described lever inside is provided with store battery and controller, and described lever is provided with trip switch, being provided with LED in described semicircle scaleplate and compasses leg, described LED is connected with trip switch with store battery respectively by wire.
As preferably, described graphical boxes comprises square and circle.
The utility model reasonable in design, easy for operation, by arranging ruler, half divided circle, straight line is achieved very much with compasses, curved line and circle, the mapping operation of circular arc and the measurement of angle, in addition base back surface arrange magnet can directly and blackboard mutually inhale even, arrange in semicircle scaleplate and compasses leg and it is provided with LED, described LED is connected with trip switch with store battery respectively by wire, blast can measure antenna case, the angle of plane figure can be measured easily, required angle can also be drawn easily, for mathematics teaching provides conveniently.
