Description
Technical field
The utility model relates to a kind of Multifunctional draughting and simulation planar linkage teaching aid, belongs to teaching aid.
Background technology
At present, the set square, meter ruler, compasses, protractor etc. of conventional teaching are not only large but also be heavyly inconvenient to carry, and graphic capability is limited, and a lot of geometric figure can only with sensation picture, and error is large.Therefore, overcome above-mentioned shortcoming to also lacking one people, light small and exquisite, graphic capability is strong, draw accurate Multifunctional draughting and simulation planar linkage teaching aid.
Summary of the invention
In order to overcome typical graphics teaching aid heaviness not Portable belt, the shortcoming that graphic capability is poor, error is large, the utility model provides a kind of Multifunctional draughting and simulation planar linkage teaching aid.
The utility model is achieved in that a kind of Multifunctional draughting and simulation planar linkage teaching aid, comprises chi ring, tape, tape snap close, axis trepanning, increasing dish, master, axis, interior slide rail, air level, main scale, dial, variable connecting rod, through-core hole, bracket panel, magnet, pulley, the tape measure of movable axis is provided with centered by master, inelastic tape is provided with in master, the outer tape exit of master is provided with tape snap close, tape chi head is provided with chi ring, axis two ends are all higher than master, axis center is provided with through-core hole, the pulley perpendicular to variable connecting rod end is inserted with in through-core hole, magnet is provided with bottom axis, axis lower end is provided with the circle increasing dish of axis trepanning through center, the top of increasing dish is main scale, the bottom of main scale is provided with magnet, the chi head place of main scale is provided with vertical two air levels with being parallel to chi limit, chi limit place without scale is provided with interior slide rail, the upper right side of main scale is provided with circular dial, center, the dial back side is provided with two rotatable variable connecting rods, it is the bracket panel of line wheel shape between dial and main scale, bracket panel center is provided with through-core hole, the pulley perpendicular to variable connecting rod end is inserted with in through-core hole, the bottom of bracket panel is provided with magnet.
During use, the motion of the various plane geometric figures such as positive round, ellipse, parabola or simulation planar linkage mechanism can be drawn quickly and easily by the flexible collocation of master, increasing dish, bracket panel, main scale, variable connecting rod on blackboard.
The beneficial effects of the utility model are light small and exquisite, and graphic capability is strong, draw accurately, can also simulate the motion of planar linkage mechanism.
