Abstract

The utility model relates to stationery articles, particularly relates to a rule capable of being used for drawing various conventional mathematical patterns. The rule comprises a ruler main body; hollow mathematical pattern models are arranged on the ruler main body; the mathematical pattern models include one or more of an answer sheet filling-out model, a cube model, a protractor model, a circle model, a hexagon model, a hyperbola model, an ellipse model, a cone model, a multi-rhombus model, a parabola model, a sine function model, a triangle model and a coordinate axes model; and dimensions, mathematical graphs or mathematical formulas are also carved or printed on the mathematical pattern models. The multifunctional rule has the advantages of convenient use and accurate dimensions of drawn patterns.

Description

Multifunctional ruler

Technical field

The utility model relates to a kind of stationery, relates in particular to a kind of ruler of the multiple mathematics figure commonly used that can draw.

Background technology

Drawing personnel or student etc. need often to draw the personnel of the common figure of mathematics; when drawing circle, ellipse, polygon, cone, cylinder, parabola figures; all need be by drafting instrument; be difficult to the level and smooth curve that draws by hand; but need be by a plurality of instruments such as ruler, compasses; the figure that has does not have ready-made instrument also to need artificial calculating just can draw, and this kind drafting method is wasted time and energy, but also inaccurate.

Summary of the invention

In order to overcome above-mentioned defective, it is a kind of easy to carry that the utility model provides, and the multifunctional ruler of the multiple figure commonly used that can draw.

Multifunctional ruler of the present utility model comprises the ruler main body, and described ruler main body is provided with the model of the picture mathematic graph of hollow out.

Wherein, described mathematic graph model is that answering card is filled in one or more in model, square model, protractor model, circle model, hexagon model, hyperbolic model, model of ellipse, cone model, many ribs cube model, parabola model, SIN function model, triangle model, the reference axis model.

Also carve or be printed with size, mathematic curve figure or mathematical formulae on the model of corresponding picture mathematic graph on the described ruler main body.

Multifunctional ruler of the present utility model, except the basic function that can draw straight line of ruler, multiple mathematic graph commonly used also can draw, as, can fill in answering card, draw square, the angle of painter's paraphernalia body, draw circle, draw hexagon, draw hyperbola, draw oval, draw cone, draw many ribs cube, draw parabola, draw the SIN function curve, draw triangle, draw multiple figures such as reference axis.Multifunctional ruler of the present utility model portably uses conveniently, and various figure moulds are compact to design, and the figure that draws is accurate.

Introduce multifunctional ruler of the present utility model in detail below in conjunction with accompanying drawing.

Description of drawings

Fig. 1 is the front view of multifunctional ruler of the present utility model.

The specific embodiment

As shown in the figure, multifunctional ruler of the present utility model comprises the ruler main body, and described ruler main body is provided with the model of the picture mathematic graph of hollow out.Described mathematic graph model is that answering card is filled in one or more in model 1,

square model

2,3, protractor model 4, circle model 5, hexagon model 6, hyperbolic model 7, model of ellipse 8, cone model 9, many

ribs cube model

15,16, parabola model 13, SIN function model 14, triangle model 17, the reference axis model.

Wherein drawing the square model, is up and down two

parallelogram

2,3 that draw earlier, and then the angle that connects this two quadrangles correspondence gets final product.In like manner, draw taper shape, the ellipse 9 that can draw is earlier determined the point of oval top then, connects the periphery of this point and ellipse 9 then.Same method can be with 10,11 three terrace with edges that draw, with 15,16 six terrace with edges that draw.Can also be with 17 right angled triangles (comprising the direct triangle of isosceles) that draw.

On described ruler, also print or be carved with size, pattern, formula or the mathematic curve model etc. of correspondence in addition.

Multifunctional ruler of the present utility model, except the basic function that can draw straight line of common ruler, multiple mathematic graph commonly used also can draw, as, can fill in answering card, draw square, the angle of painter's paraphernalia body, draw circle, draw hexagon, draw hyperbola, draw oval, draw cone, draw many ribs cube, draw parabola, draw the SIN function curve, draw triangle, draw multiple figures such as reference axis.Multifunctional ruler of the present utility model portably uses conveniently, and various figure moulds are compact to design, and the figure that draws is accurate.

The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all within spirit of the present utility model and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.

Claims

1. a multifunctional ruler is characterized in that, comprises the ruler main body, and described ruler main body is provided with the model of the picture mathematic graph of hollow out.

2. multifunctional ruler as claimed in claim 1, it is characterized in that described mathematic graph model is that answering card is filled in one or more in model, square model, protractor model, circle model, hexagon model, hyperbolic model, model of ellipse, cone model, many ribs cube model, parabola model, SIN function model, triangle model, the reference axis model.
