Abstract
The utility model relates to a drawing rule for mathematical education, including horizontal drawing rule, be equipped with the circulator on the horizontal drawing rule, the circulator is connected with drawing rule one end, be equipped with the guide bar on the drawing rule, the guide bar all is located the arc spout on the bevel protractor, be fixed connection between bevel protractor and the horizontal drawing rule, be equipped with the drawing scale on horizontal fixed ruler, the drawing rule, it is equipped with fixed suction cup on the surface to be close to blackboard one side on the horizontal drawing rule. The utility model discloses when mr need draw on the mathematics class, pass through fixed suction cup with horizontal drawing rule and fix on the blackboard, avoided pressing of mr, reduced intensity of labour, can go out different contained angles straight line under the effect of horizontal drawing rule, drawing rule, can improve operating speed like this, improved the efficiency of drawing.
Description
Technical field
The utility model relates to instructional technology field, particularly relates to a kind of mathematical education drawing rule.
Background technology
Mathematics can be divided into two large classes, and a class is pure mathematics, and a class is applied mathematics.Pure mathematics is also background mathematics, specializes in the inherent laws of mathematics itself.The algebraically introduced in middle and primary schools' textbook, geometry, calculus, probability theory knowledge, all belong to pure mathematics.A distinguishing feature of pure mathematics is exactly temporarily bypass particular content, with the quantitative relation of pure form research things and space form.Such as studying trapezoidal areal calculation formula, is the area in trapezoidal rice field as it, or the area of trapezoidal machine components, all unimportant, the quantitative relation just lain in this geometric figure that everybody is concerned about.Applied mathematics is then conceived to natural phenomena is described, solving practical problems is the bridge between pure mathematics and science and technology.The large daily life of a family says it is information-intensive society now, specializes in " information theory " of information, is exactly an important subdiscipline in applied mathematics.
At present, when will draw in mathematical education process, the angle straight line drawing different angles that existing drawing rule can not be very fast, in drawing course, need teacher to press drawing rule with hand, cause troublesome poeration, efficiency is low simultaneously.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of mathematical education drawing rule.
The utility model is achieved through the following technical solutions:
A kind of mathematical education drawing rule, comprise horizontal drawing rule, described horizontal drawing rule is provided with circulator, described circulator is connected with drawing rule one end, described drawing rule is provided with guide post, and described guide post is all positioned at the arc chute on bevel protractor, for being fixedly connected with between described bevel protractor with horizontal drawing rule, described horizontal fixed ruler, drawing rule are provided with drawing scale, and described horizontal drawing rule is provided with fixing sucking disk on the surface near blackboard side.
As optimal technical scheme of the present utility model, the axis of described circulator is horizontally disposed.
As optimal technical scheme of the present utility model, described drawing rule is fixedly connected with between guide post.
As optimal technical scheme of the present utility model, be fixedly connected with between described fixing sucking disk with horizontal drawing rule.
Compared with prior art, the beneficial effects of the utility model are: the utility model structure is simple, reasonable in design, the utility model is by arranging drawing rule, bevel protractor and fixing sucking disk, when such teacher needs to draw on mathematics class, horizontal drawing rule is fixed on blackboard by fixing sucking disk, avoid the pressing of teacher, reduce labour intensity, different angle straight line can be gone out under the effect of horizontal drawing rule, drawing rule, can service speed be improve like this, improve the efficiency of drawing.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1. horizontal drawing rule; 2. circulator; 3. drawing rule; 4. guide post; 5. bevel protractor; 6. arc chute; 7. fixing sucking disk.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 1, Fig. 1 is structural representation of the present utility model.
A kind of mathematical education drawing rule, comprise horizontal drawing rule 1, described horizontal drawing rule 1 is provided with circulator 2, and the axis of wherein said circulator 2 is horizontally disposed.Described circulator 2 is connected with drawing rule 3 one end, and described drawing rule 3 is provided with guide post 4, and wherein said drawing rule 3 is fixedly connected with between guide post 4.Described guide post 4 is all positioned at the arc chute 6 on bevel protractor 5, for being fixedly connected with between described bevel protractor 5 with horizontal drawing rule 1, described horizontal fixed ruler 1, drawing rule 3 are provided with drawing scale, described horizontal drawing rule 1 is provided with fixing sucking disk 7 on the surface near blackboard side, is fixedly connected with between wherein said fixing sucking disk 7 with horizontal drawing rule 1.When such teacher needs to draw on mathematics class, horizontal drawing rule is fixed on blackboard by fixing sucking disk 7, avoid the pressing of teacher, reduce labour intensity, different angle straight line can be gone out under the effect of horizontal drawing rule 1, drawing rule 3, can service speed be improve like this, improve the efficiency of drawing.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
