Abstract
The utility model discloses a multifunctional drawing board which is a transparent plastic board, wherein the overall shape of the multifunctional drawing board is a combination of a rectangle and a semicircle; scales are marked on the periphery of the rectangle; the rectangle is a ruler body; the rectangle is internally provided with hollowed triangles, a square, a parallelogram, circles, ellipses, a hyperbola and a parabola template; a groove for holding a drawing pen is formed in the left side of the rectangle; the semicircle on the right side of the rectangle is a protractor. The drawing board can be used for drawing straight lines, triangles, parallelograms, squares, rectangles, trapezoids, rhombuses, arbitrary quadrilaterals as well as circles, ellipses, hyperbolas, parabolas and other common graphs, the pen and the drawing board are not separated, and the problem that the use is not convenient as tools are separately arranged when graphs are drawn is solved.
Description
Technical field
The utility model relates to a kind of drawing board, is mainly that the student is used for the instrument of drawing.
Background technology
At present, the student when drawing planar graph (as straight line, triangle, quadrangle), the instruments such as Multipurpose ruler or set square.If draw circle, draw ellipse, draw hyperbola, during the curve maps such as picture parabola, ruler or set square just seem not have much use, the quality of picture depends on student's drawing level fully.Some multifunctional drawing board on market, although can draw circle and oval figure, the insufficiency of waiting.And pen all separates with chart board.
Summary of the invention
The utility model is intended to solve the problem that can not effectively draw conic section figure (circle, ellipse, hyperbola, parabola etc.) with set square and ruler, and drawing pen is not separated with chart board, and a kind of multifunctional drawing board is provided.
For solving the problems of the technologies described above the technical scheme of taking, be, multifunctional drawing board, be a transparent plastic plate, and its global shape is a rectangle and a semicircular combination.The rectangle outer perimeter indicates scale, is the ruler body; Rectangle inside is provided with the geometry of hollow out, as triangle, square and parallelogram, circle, ellipse, hyperbola, parabola template; The rectangle left side is provided with the groove of placing drawing pen.The semicircle on rectangle the right is made as protractor, and a parabolic wire casing is arranged in the middle of it.
Superiority of the present utility model is: provide template for drawing conic section (circle, ellipse, hyperbola, parabola etc.), provided convenience for mapping, reduced the mapping time.Simultaneously, provide a place of putting paintbrush, allowed paintbrush and drawing board form an integral body.
The accompanying drawing explanation
Fig. 1 is the utility model structural representation.
The specific embodiment
Multifunctional drawing board, be a transparent plastic plate, and its global shape is a rectangle and a semicircular combination.
LongSquare length is 200mm, and semicircle diameter is 120mm.The rectangle outer perimeter indicates scale, is the ruler body; Rectangle inside is provided with the geometry of hollow out, and drawing board contains: two right angled triangles, and one is the triangle (1) of 45° angle, two right angle length of sides are 40mm; One is the triangle (2) at 30 ° of angles, the long 30mm of right angle minor face, long length of side 60mm.Another square (3), length of side 40mm.A parallelogram (4), two length of sides are respectively 40mm, 60mm; Three circles (5) (6) (7) that diameter does not wait, diameter of a circle is respectively 20mm.30mm, 40mm.An ellipse (8), major axis and minor axis length are respectively 60mm and 40mm., a hyperbola (9), the real axis of curve is long is 40mm., a parabola (10); There is the groove (11) of laying paintbrush in the drawing board left side, and groove (11) length is 100mm.A protractor.
When drawing straight line or line segment, yardstick all is carved with on drawing board top and the left side; Draw triangle, two kinds of templates are arranged, selected angle is that 30 degree or 45 are spent as required; Drawing circle, parabola, ellipse, during hyperbola, need only be pen near template or be enclosed within template that move just can one-tenth figure, simple and fast saves time.Parallelogram; Triangle; Circle; In the middle of oval, it is all hollow out; In the middle of these two curves of hyperbola and parabola, it is also hollow out.
Three kinds of circles that radius is different are set, can meet the different demands of drawing.And oval, hyperbola, it is a kind of that parabola only arranges, and mainly considers that the drawing board area is limited, can not arrange too much, in addition, also need not.When mapping, can need to give voluntarily its length according to exercise question.
Although the utility model discloses as above with preferred embodiments, and non-limiting the utility model, all and akin design of the utility model function, all contained by the utility model.
