A kind of multifunctional drawing plate described in the utility model is achieved in that matrix is provided with large scale and undersized geometric figure mould, described geometric figure mould can be made circle, ellipse, triangle, square, rectangle, parallelogram, pentagon and/or be polygon, then along the edge setting-out of each evacuated mould, the planar graph of the above various different sizes that can draw; After drawing what a planar graph, ruler translation up or down one segment distance, the same planar graph that draws again, the corresponding vertex with two planar graphs connects with straight line at last, the solid figure of the planar graph correspondence of can drawing; Also be provided with various curvilinear mold on the matrix, described curvilinear mold can be made to be sinusoidal line cambered surface, positive tangent cambered surface, cotangent bank face, parabola cambered surface and/or to be the hyperbola cambered surface, along two edge setting-outs of each curvilinear mold, can draw the different curve of above various openings of sizes respectively; Also be provided with the metric and English rule on the matrix, some special angle mark especially on rule as 30 degree, 45 degree and 60 trigonometric function values of spending angles and are the trigonometric function value tag slot, can also be carved with corresponding trigonometric function computing formula on the matrix; In addition, also be provided with protractor on matrix, the center of circle of utilization hornwork and edge can draw fan-shaped at any angle.

Advantage of the present utility model is: a kind of multifunctional drawing plate is provided, can have conveniently made multiple plane geometric figure, solid geometry figure and curve, had the advantages that function is complete, purposes is wide, cost is low.

Description of drawings

Fig. 1 is the overall structure schematic diagram of a kind of multifunctional drawing board described in the utility model;

The division mark is as follows in the accompanying drawing: 1, matrix; 2, geometric figure mould; 3, curvilinear mold; 4, metric and English rule; 5, protractor; 6, trigonometric function value tag slot.

The specific embodiment

As shown in Figure 1, be a kind of overall structure schematic diagram of multifunctional drawing board, comprise matrix 1; The middle part of described matrix 1 offers geometric figure mould 2 and curvilinear mold 3, and the edge is provided with metric and English rule 4 and protractor 5; Described geometric figure mould 2 is various polygons and circular, oval die cavitys of hollow, comprises large-sized oval artwork A, circular artwork B, triangle artwork C, square artwork D, rectangle artwork E, parallelogram artwork F, pentagon artwork G, hexagon artwork H and undersized oval artwork I, circular artwork J, triangle artwork K, square artwork L, rectangle artwork M, parallelogram artwork N, pentagon artwork O and hexagon artwork P; Described curvilinear mold 3 is slotted hole structures, and the both sides of the edge of slotted hole are provided with opening, the curve cambered surface that size dimension is different; The center of circle of described protractor 5 is provided with perforation, and the outward flange of protractor 5 is provided with the graduation mark district of dead slot and 0-180 degree.In addition, described metric and English rule 4 is provided with trigonometric function value tag slot 6, indicates some special angle especially, and described trigonometric function value tag slot 6 is 30 degree, 45 degree and/or is the trigonometric function value tag slot 6 at 60 degree angles.

When needs draw circles cone figure, the ellipse that can be earlier draws along the edge of oval artwork B is drawn a point again above this is oval-shaped, this point is connected with straight line with two end points of oval major semiaxis respectively again, can finish the drafting of cone.

When needs are drawn the cuboid figure, a parallelogram can be earlier draws along the edge of parallelogram artwork F, matrix 1 translation one segment distance upwards, a same parallelogram again draws, then four corresponding vertexs of drawn two parallelogram are coupled together with straight line, can finish the drafting of cuboid.

When needs are drawn the pentagonal prism figure, the pentagon that can be earlier draws along the edge of pentagon artwork G, matrix 1 translation one segment distance upwards, a same pentagon again draws, then drawn two pentagonal five corresponding vertexs are coupled together with straight line, can finish the drafting of pentagonal prism.

When needs are drawn the spheroid figure, the circle of can be earlier drawing along the edge of circular artwork B, an ellipse again draws along the edge of oval artwork A, because oval major semiaxis equates with the radius of circle, the end points of oval two major semiaxis is dropped on the circumference of drawn circle, oval artwork A is revolved turn 90 degrees again, an ellipse again draws, the end points of oval-shaped two major semiaxis is dropped on the drawn circumference, can finish the drafting of spheroid.

Obviously the foregoing description is not to restriction of the present utility model, and above-mentioned a kind of multifunctional drawing board can also have other many variations.Though gone through the utility model in conjunction with above-mentioned example, some that should be understood that professional person in the industry can expect apparently are identical, and alternative scheme all falls within the protection domain that the utility model claim limited.
