Abstract
A curve drawing template with groove mainly comprises a white plastic floor; the floor is provided with a plurality of parabolas, power function curves, exponential function curves, logarithm function curves, hyperbolas, trigonometric function curves, polar coordinate function curves, ellipses of different proportions and sizes, which are all provided with groove. The curves or ellipses above, and circles with different diameters can be quickly and accurately drawn by taking the curve drawing template beneath papers. The template can be extensively used by students, teachers and scientific and technical personnel.
Description
The utility model relates to a kind of drawing instrument.Relate in particular to the curves drawing template of using when a kind of students' work is drawn.
The student will often draw the many figures in the analytic geometry when learning mathematics, as ellipse of parabola, hyperbola, trigonometric function curve, different size or curvature etc.But tool combinations such as the set square that the student was equipped with, protractor, compasses together, and are all powerless to drawing above curvilinear figure, can only use graph paper to put in the above and a little retouch line, draw not only nonstandard but also waste time and energy.The drawing template of Chu Shouing also has only and else can draw some simple curves in the market.
The purpose of this utility model is to provide a kind of complete function, draws fast, curves drawing template accurately and conveniently.
The technical solution of the utility model is achieved in that
A kind of curves drawing template mainly is made up of a white plastic base plate.
Be printed on multiple curve and ellipse figure and coordinate line above the plastic plate, and all have groove.
During drawing, if with this plate pad under paper, the curvilinear figure on the plate will see through paper and reflect.The student just can be on paper along plate upper curve groove as long as put accurate respective graphical with pen, and the curve of the rule standard of drawing easily comes.
Below in conjunction with accompanying drawing the utility model is described in further detail:
Figure one is a structural representation of the present utility model.
Shown in figure one:
A is that the parabola group is made up of several parabolas;
B is the polar coordinates function curve, as: Archimedes spiral.
C is the power function curve group.
D is index and logarithmic function curve group.
E is a hyperbolic function curve group.
F is a trigonometric function curve group.
G is circle and ellipse figure group.
Claims (2)
1, a kind of curves drawing template with groove mainly is made up of a white plastic base plate, is shaped on curvilinear figure on the base plate, it is characterized in that:
(1), is shaped on parabola, power function curve, exponential function curve, logarithmic function curve, hyperbola, trigonometric function curve, the Archimedes spiral that has groove, the circle of different proportion and size and ellipse on the base plate.
(2), various curve grouping set together, form parabola group, power function curve group, exponential function curve and logarithmic function curve group, hyperbola group, trigonometric function curve group, circle and ellipse figure group.
2, curves drawing template according to claim 1 is characterized in that being shaped on the white plastic plate ellipse of the different curvatures of the array with groove, and every group of ellipse integrated with one heart by a plurality of ellipses of identical curvature, different sizes again.
