Abstract

The utility model relates to a multifunctional ruler used for students which is composed of a ruler and an empty groove of a ruler edge parallel line arranged on the ruler, an empty groove of a ruler edge vertical line, and a circular groove. The empty groove can respectively correspond to a scale mark, so that the student can dot along the scale mark. The geometrical figure can be rapidly and accurately drawn out in connecting line mode, and therefore, the learning efficiency can be enhanced.

Description

Multifunctional ruler
The utility model relates to a kind of multifunctional ruler, the multifunctional ruler that particularly a kind of student uses.
Existing student comprises multi-functional ruler, multi-functional triangular ruler with multifunctional ruler, is provided with scale on the chi limit, is provided with several figure dead slots on chi.This class chi is except setting-out, amount length, draw the geometric figure that several dead slot limited soon, geometric figures such as the different big or small triangles of can not be very soon often using with the students in middle and primary schools that draw exactly, square, rectangle.
The purpose of this utility model provides a kind of chi that can overcome above-mentioned defective.
The utility model adopts four kinds of schemes to realize above-mentioned purpose.
First kind of scheme is to be provided with respectively on chi: along the parallel lines dead slot group of the graduation mark setting that is parallel to the chi limit; Arc groove group along the setting of limbus line; The edge is perpendicular to the chi limit vertical line dead slot 3 of the graduation mark setting on chi limit; Two rows, the machine-readable pane of the picture hole group that the slot of 5 same sizes of every row constitutes; This chi is the rectangle chi.
Second kind of scheme is to be provided with on chi: each the angular bisector intersection point with chi is the center of circle, and along the circular groove 5 that the limbus line is provided with, this chi is 30 degree right angled triangle chis.
The third scheme is to be provided with on chi: the isosceles triangle graphometer that is provided with along the right angle, this chi is the isosceles right triangle chi.
The 4th kind of scheme is to be provided with on chi: along the chi limit parallel lines dead slot 6 of the graduation mark setting that is parallel to the chi limit; The edge is perpendicular to the chi limit vertical line dead slot 3 of the graduation mark setting on chi limit; The machine-readable pane of the picture hole group that the slot of 5 same sizes of the two every rows of row constitutes; This chi is the rectangle chi.
Since the utility model be provided with chi in the corresponding dead slot of scale, the student can get ready on graduation mark, the line geometric figure that draws rapidly and exactly, thereby greatly improved learning efficiency.
Description of drawings is as follows:
Fig. 1 is first kind of scheme schematic diagram of the utility model;
Fig. 2 is second kind of scheme schematic diagram of the utility model;
Fig. 3 is the third scheme schematic diagram of the utility model;
Fig. 4 is the 4th kind of scheme schematic diagram of the utility model.
Below in conjunction with accompanying drawing the utility model is done detailed description.
Fig. 1 shows the structure that chi is the rectangle chi, and it comprises and being separately positioned on the chi:
Chi limit parallel lines dead slot group, it comprises that two edges are parallel to dead slot 1-1, the 1-2 of the graduation mark setting on chi limit, the scale of this graduation mark is corresponding with chi limit scale.Its function and effect are:
A, by connecting the point that is drawn on dead slot graduation mark and the chi limit graduation mark respectively, square, rectangle, isosceles trapezoid, right-angled trapezium, parallel lines, isosceles triangle, right angled triangle can draw respectively.
B, to cut two corresponding line segments that straight line intercepted with three parallel lines on chi limit and dead slot limit proportional.
C, respectively get the 0-point on two parallel graduation marks, 2 points of getting identical numerical value on the parallel graduation mark in centre equidistant apart from two parallel graduation marks are (if get 1,5
Figure Y9720159700041
2 points), 4 lines are rhombus (4 lines are that an angle is the rhombus of 120 degree).
D, with the both sides of two parallel graduation mark rescinded angles, two triangles that intercepted are similar.
E, get the end points of isometric line segment on two parallel graduation marks, 4 lines are parallelogram.
The arc groove group, it comprises 2 the dead slot 2-1, the 2-2 that are provided with along the limbus line, its function and effect are: by get line can draw equilateral triangle, regular pentagon, regular hexagon ready on the arc groove graduation mark.Chi limit vertical line dead slot 3, this dead slot be along the graduation mark setting perpendicular to the chi limit, scale with
Figure Y9720159700042
Cm is a unit.Its function and effect are:
A, take up an official post at the vertical scale line and to get a bit, at two points of chi limit intersection point two side-draws apart from the identical numerical value of intersection point, 3 lines are isosceles triangle.
B, on vertical scale with 3 points of the identical numerical value of intersection point two side-draws, 3 lines are equilateral triangle.Get intersection point a bit, respectively get an identical numerical point with the chi limit on vertical scale, 3 lines are 30 degree right angled triangles.
Draw machine-readable pane hole group: it comprises two rows, slot 4-1, the 4-2 of 5 same sizes of every row, and its function and effect are:
Picture the pane on the general examination for students from various schools machine-readable answer sheet of entering a higher school of graduating from junior middle school.
Fig. 2 shows the structure that chi is 60 degree right angled triangle chis.It is provided with:
Circular groove 5, it is the center of circle with each angular bisector intersection point of set square, along the dead slot of limbus line setting.Its function and effect are:
By on the arc groove graduation mark, getting line can draw equilateral triangle, square, regular pentagon, regular hexagon and octagon ready.
Fig. 3 shows the structure that chi is the isosceles right triangle chi.Be provided with the isosceles triangle graphometer along the right angle.
Fig. 4 shows the structure that chi is the rectangle chi, and it comprises and being separately positioned on the chi:
Chi limit parallel lines dead slot 6; This dead slot is along the graduation mark setting that is parallel to the chi limit, and the scale of this graduation mark is corresponding with the scale on chi limit.Its function and effect are:
By connect respectively on dead slot 6 graduation marks and the chi limit on the point that drawn, the parallel lines that can draw respectively, rectangle, isosceles trapezoid, right-angled trapezium, parallelogram, rhombus.
Be provided with its function chi limit vertical line dead slot 3 identical with above-mentioned rectangle chi, draw machine-readable pane hole group with structure.
