Abstract
The utility model discloses a drawing rule for mathematics, and the drawing rule comprises a first straight rule and a second straight rule, which are hinged with each other, wherein the first straight rule is respectively provided with a circle, an oval, a regular hexagon, an equilateral triangle, a isosceles right triangle and a right-angled triangle with one angle of 30 DEG, and one long edge of the first straight rule is also provided with scales; and the second straight rule is respectively provided with a first parabola cavity with an equation of y=x<2>, a second parabola cavity with an equation of y=0.5*2, a sine function curve cavity and a cosine function curve cavity, a short edge of the second straight rule is provided with a graphometer, and two long edges of the second straight rule are respectively provided with scales. Two drawing rules are hinged with each other, so that the two straight rules can be used according to the requirement, and the two straight rules can be combined together when not in use so as not to occupy the space. The drawing rule is provided with multiple conventional figures, so that the drawing rule is convenient for students to use, and the time can be saved. The drawing rule is simple in structure, reasonable in design, convenient to use and convenient to popularize and use.
Description
Technical field
The utility model relates to a kind of mathematics and uses drawing instrument, is specifically related to a kind of mathematics that can draw multiple figure and uses drawing rule, belongs to the daily living article technical field.
Background technology
In learning process; The student is through some fixing figure of using of regular meeting's repeatability; For example circular, parabola shaped, oval, or the like; If according to the own drafting of curve then can waste great amount of time, if figure commonly used in some learning processes is fixed on certain mould, directly drafting then can be practiced thrift a lot of time in use.But the drawing instrument function of selling in the market is more single, still ruler, set square, protractor relatively more commonly used, and the replacing instrument that need not stop in use uses very inconvenient.
Summary of the invention
The utility model provides a kind of mathematics to use drawing rule to above-mentioned deficiency, and its ability diverse in function is simple in structure, easy to use.
The utility model is realized through following measure:
A kind of mathematics is used drawing rule; It is characterized in that: comprise two first rulers that are hinged and second ruler; Be respectively equipped with circle, ellipse, regular hexagon, equilateral triangle, isosceles right triangle, one jiao on said first ruler and be 30 ° right angled triangle, also be provided with scale on the long limit of first ruler; Being respectively equipped with equation on said second ruler is y=x
2The first parabola cavity, equation be y=0.5x
2The second parabola cavity, SIN function curve cavity and cosine function curve cavity, the minor face of second ruler is provided with graphometer, two long limits are provided with scale.
Beneficial effect:
The utility model improves drawing rule, two drawing rules has been carried out hinged, can use two rulers on demand, again can not the time two rulers are incorporated into together, do not take up room.Be provided with multiple daily figure commonly used in the drawing rule, made things convenient for student's use, practiced thrift the time.The utility model is simple in structure, reasonable in design, and is easy to use, easy to utilize.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment 1;
Among the figure, 1, first ruler, 2, second ruler, 3, circle; 4, ellipse, 5, regular hexagon, 6, equilateral triangle, 7, isosceles right triangle; 8, one jiao is 30 ° right angled triangle, 9, the first parabola cavity, 10, the second parabola cavity; 11, SIN function curve cavity, 12, cosine function curve cavity, 13, graphometer.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is further set forth, the explanation effect is only played in following explanation, its content is not limited.
Embodiment 1
Mathematics as shown in Figure 1 is used drawing rule; It is characterized in that; Comprise two first rulers 1 that are hinged and second ruler 2; Be respectively equipped with on said first ruler circular 3, oval 4, regular hexagon 5, equilateral triangle 6, isosceles right triangle 7, one jiao be also to be provided with scale on 30 ° the long limit of right angled triangle 8, the first rulers; Being respectively equipped with equation on said second ruler is y=x
2The first parabola cavity 9, equation be y=0.5x
2The minor face of the second parabola cavity 10, SIN function curve cavity 11 and cosine function curve cavity 12, the second rulers be provided with graphometer 13, two long limits and be provided with scale.
It more than is description to the utility model; But the protection domain of the utility model is not limited thereto; Variation that those skilled in the art can expect in the technical scope that the utility model disclosed easily or replacement all should be encompassed within the protection domain of the utility model.
