Abstract
The utility model relates to a mathematics drawing rule, including horizontal drawing rule, horizontal drawing rule no. 1 is served and is equipped with first circulator, first circulator is connected with first drawing rule one end, is equipped with the second circulator on the other end, the second circulator is connected with second drawing rule one end, horizontal drawing rule, first drawing rule are equipped with the drawing scale with the second drawing rule on the surface, horizontal drawing rule middle part is equipped with the water cavity, be equipped with balanced bubble in the water cavity. The utility model discloses mr goes up need draw the time at mathematics class, can paint the straight line through horizontal drawing rule, can be in the water cavity middle part through balanced bubble simultaneously and determine whether level of straight line, avoids drawing through the naked eye, can go out the diameter and the parallelogram of different contained angles simultaneously under the effect of first drawing rule, second drawing rule, can improve operating speed like this, has improved the efficiency of drawing.
Description
Technical field
The utility model relates to instructional technology field, particularly relates to a kind of mathematical 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, generally observe the line that well can not draw comparatively level by naked eyes when needing picture straight line, the angle straight line drawing different angles that existing drawing rule can not be very fast simultaneously and parallelogram, cause troublesome poeration, efficiency is low.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of mathematical drawing rule.
The utility model is achieved through the following technical solutions:
A kind of mathematical drawing rule, comprise horizontal drawing rule, described horizontal drawing rule one end is provided with the first circulator, described first circulator is connected with first drawing rule one end, the other end is provided with the second circulator, and described second circulator is connected with second drawing rule one end, and described horizontal drawing rule, the first drawing rule and the second drawing rule are provided with drawing scale on the surface, be provided with water cavity in the middle part of described horizontal drawing rule, in described water cavity, be provided with balance bubble.
As optimal technical scheme of the present utility model, the axis of described first circulator, the second circulator is horizontally disposed.
As optimal technical scheme of the present utility model, the length of described first drawing rule, the second drawing rule is identical or not identical.
As optimal technical scheme of the present utility model, described water cavity is embedded on 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 horizontal drawing rule, first drawing rule and the second drawing rule, when such teacher needs to draw on mathematics class, drawing beeline can be carried out by horizontal drawing rule, can be in by balance bubble simultaneously and in the middle part of water cavity, judge straight line whether level, avoid being drawn by naked eyes, simultaneously at the first drawing rule, straight line and the parallelogram of different angle can be gone out under the effect of the second drawing rule, service speed can 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. the first circulator; 3. the first drawing rule; 4. the second circulator; 5. the second drawing rule; 6. water cavity; 7. balance bubble.
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 drawing rule, comprise horizontal drawing rule 1, described horizontal drawing rule 1 one end is provided with the first circulator 2, described first circulator 2 is connected with first drawing rule 3 one end, the other end is provided with the second circulator 4, and the axis of wherein said first circulator 2, second circulator 4 is horizontally disposed.Described second circulator 4 is connected with second drawing rule 5 one end, and the length of wherein said first drawing rule 3, second drawing rule 5 is identical or not identical.Described horizontal drawing rule 1, first drawing rule 3 and the second drawing rule 5 are provided with drawing scale on the surface, water cavity 6 is provided with in the middle part of described horizontal drawing rule 1, be provided with balance bubble 7 in described water cavity 6, wherein said water cavity 6 is embedded on horizontal drawing rule 1, can judge drawing straight line whether level like this.
Its detailed description of the invention is: when teacher needs to draw on mathematics class like this, drawing beeline can be carried out by horizontal drawing rule 1, can be in by balance bubble 7 simultaneously and in the middle part of water cavity 6, judge straight line whether level, avoid being drawn by naked eyes, straight line and the parallelogram of different angle can be gone out under the effect of the first drawing rule 3, second drawing rule 5 simultaneously, 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.
