Abstract
The utility model discloses a student-used multipurpose drafting scale, comprising two small-sized straightedges and a wide straightedge. The two small-sized straightedges are hinged with the wide straightedge; triangles with the different shapes are formed, for being selected during drafting graphics. Millimetre scales are engraved on both sides of the wide straightedge; one end is protractor with the angle of 90 DEG and is provided with a plurality of positioning small holes. When the male pin of the small-sized straightedge is inserted in some small hole, the specific triangle is formed. In addition, the small-sized straightedges and the wide straightedge can be folded into a T-square, satisfying the requirements of drafting the different graphics. The drafting scale is convenience for drafting the graphics for primary and middle school students.
Description
The utility model is the folding drawing rule of using more.
At present, the student particularly learns courses such as geometry in learning process, need describe the figure of different shape, normally utilizes ruler, set square, protractor and compasses to finish.
The purpose of this utility model is that the function of collection set square, protractor and ruler is an one, and the student is saved time when drawing geometric figure, and easy to carry.
Further describe below in conjunction with accompanying drawing and enforcement: accompanying drawing is the schematic diagram of drawing rule, (1) the wide ruler among the figure, (2) ruler one, (3) ruler two, (4) rivet, (5) pin, (6) locating hole.
With reference to the accompanying drawings, the utility model is the drawing rule of making of the transparent material that certain mechanical strength is arranged, formed by ruler one (2), ruler two (3) and wide ruler (1), article two, little ruler links to each other with wide ruler with rivet (4), utilize the diverse location of three rulers, can directly draw out difform triangle.The millimeter scale of common ruler is carved with on the both sides of wide ruler, one end is 90 ° of protractors, and on chi, be provided with some location apertures (6), when the pin (5) of ruler (3 ') inserts these apertures respectively, just can form various triangular such as right angled triangle, equilateral triangle, isosceles triangle, obtuse triangle and acute triangle between three rulers.
This drawing rule can fold into little ruler on the wide ruler, to be convenient for carrying when not mapping; Also can fold into wide ruler and form a T-square, to satisfy the needs of drawing various figures.
Claims (3)
1, a kind of folding drawing rule with transparent material making of certain mechanical strength is characterized in that two little rulers link mutually with a wide ruler.
2, according to the drawing rule of claim 1, it is characterized in that an end of wide chi is carved with 90 ° of protractors, a millimeter scale is carved with on both sides, and some location aperture is arranged.
3, according to the drawing rule of claim 1, it is characterized in that making folding form, two little rulers and wide ruler can be folded into T-square.
