Abstract

The utility model belongs to a kind of student stationery with multiple Plotting Function, is on general high transparency material plates ruler, additional series of holes and center of circle positioning rotating shaft, template curve, special angle groove, protractor scale.It combines ruler, set square, protractor, compasses and curve ruler function in the multifunctional ruler of one, by force comprehensive, is applicable to students' work and uses.Because center of circle positioning rotating shaft all has little boss in the upper and lower surface of chi, draw bowlder and can pushing down paper below, being also convenient to, by carrying ruler, carry with easy to use.

Description

Student stationery multifunctional ruler

Technical field

The utility model relates to a kind of stationery, can draw straight line easily, draw angle, measuring angle, picture are round, trace, gather multi-function in integral whole, ruler easy to use when particularly relating to students' work.

Background technology

At present, student, in arithmetic operation at ordinary times, still generally uses conventional geometric drawing instrument, such as ruler, set square, protractor, compasses etc.These typical graphics instrumental functions are single, complete a geometric figure, often need to be used alternatingly multiple drawing instrument, also have some multifunctional rulers or complex structure, or size is bigger than normal, students' work, use and carry all inconvenient, sometimes also there is no simple and easy applicable curve ruler.

Utility model content:

Single for solving above-mentioned typical graphics instrumental function, carry and use the problem of multiple drawing instrument inconvenience, the purpose of this utility model is to provide a kind of easy Geometric figure drawing multifunctional ruler, this multifunctional ruler makes full use of the transparency of material, has function that is rationally distributed, that draw straight line easily, draw angle, draw circle and curve.

For achieving the above object, the utility model adopts following design.

A kind of student stationery multifunctional ruler, on the rectangular dull and stereotyped ruler of high transparency material, comprises length scale, protractor scale, special angle groove, series of holes, two center of circle positioning rotating shafts, the template of two small sircle holes, an ellipse and two curves.

Protractor has the special angle groove of 30,45,60,90,120,135 and 150 degree, wherein 45,135 degree of line redness represent.

There is ' ten ' font groove at the center of each positioning rotating shaft.Positioning rotating shaft is rotatable, and exceeds half millimeter, upper and lower chi face.

Effect of the present utility model: common ruler, the transparency of its material is fully used, only increase by two center of circle positioning rotating shafts, pass through rational deployment, straight line can be drawn easily, draw angle, measuring angle, picture are round, trace, solve in students' work, use and carry inconvenience, sometimes also there is no the problem of simple and easy applicable curve ruler.

Detailed description of the invention:

This student stationery multifunctional ruler structure, see Fig. 1: its structure is: on the chi body-9 of the dull and stereotyped ruler of 4 centimetres wide 16 centimeter length of high transparency, two center of circle positioning rotating shafts-1, positioning rotating shaft are installed rotatable but can not feel there is gap to ruler, and exceed about half millimeter, upper and lower chi face, two center of circle positioning rotating shafts are at the two ends of chi, distance from first series of apertures is respectively 1 and 1.5 centimetre, and series of apertures distance is 1 centimetre, so can draw circle or circular arc that incremental radii is 0.5 centimetre.Ruler also comprises: 12 series of apertures-2; Protractor-6 also comprises the groove-3 of 30,45,60,90,120,135 and 150 degree of special angles; The mark " 0-7 " of ruler scale-4 is centrosymmetric; An elliptical aperture-5; Two template curves-7 and two small sircle hole-8 radiuses are 2.5 and 5 millimeters.

Center of circle positioning rotating shaft-1 structure, be also by the material manufacture of high transparency see Fig. 2: two center of circle positioning rotating shafts-1, it has a circular bosses-10, is carved with ' ten ' sign line-11 in circular bosses bottom surface in the heart, and an annulus-12 combines.
