Abstract
The utility model relates to a four-in-one ruler disk which consists of an angle gauge 1, a 45-degree right angle set square 2, a 30-degree right angle set square 6 and a straight scale 7, wherein the scale of the angle gauge 1 is 90 degrees, and the angle gauge 1 is provided with an upper set of data and a lower set of data; the right angle peak of the 45-degree right angle set square 2 is taken as a starting point, and an a edge 3 or a b edge 4 is taken as a datum line when the four-in-one ruler disk is used for measuring angle; the 30-degree right angle set square 6 is arranged at the right end of the 45-degree right angle set square 2, and an edge which is parallel with a bevel edge of the 30-degree right angle set square 6 is a wave edge 5; and the straight scale 7 is arranged at the bottom end of the ruler disk, and two ends of the straight scale 7 are provided with corresponding parallel scales. The four-in-one ruler disk combines with four rulers into a whole, thereby being capable of conveniently achieving various drawing effects, being smaller in body type, being convenient to carry, and being very practical for students.
Description
Technical field:
The utility model relates to a kind of stationery, a kind of specifically four unification chi dishes.
Background technology:
Ruler is student's the most basic instrument of drawing, and when the student draws, always takes out a cover chi tool, comprises ruler, the set square of two different angles and protractor, and because of the needs of drawing, each ruler uses by turns, and very trouble causes drawing efficiency not high.And four whole bodies of ruler are big, are inconvenient to carry, and also lose easily, cause very big trouble to the student sometimes.
For the drawing environment of providing convenience to the student, the utility model has designed a kind of four unification chi dishes, and this chi dish is that four rulers are combined as a whole, and can reach various drawing effects easily, and its build is less, is convenient for carrying.
The utility model content:
The technical scheme that its technical problem that solves the utility model adopts is: a kind of four unification chi dishes, it forms one by 2,30 ° of right angle triangles 6 of 1,45 ° of right angle triangles of protractor and ruler 7, the scale of described protractor 1 is 90, two groups of data are arranged up and down, summit, right angle with 45 ° of right angle triangles 2 during angulation is a starting point, and a limit 3 or b limit 4 are datum line; Described 30 ° of right angle triangles 6 are positioned at the right-hand member of 45 ° of right angle triangles 2, and the edge parallel with the hypotenuse of 30 ° of right angle triangles 6 is rippled edge 5; Described ruler 7 is positioned at the bottom of chi dish, ruler 7 two ends and the middle parallel scale that is provided with correspondence.
The beneficial effects of the utility model are: the utility model just four rulers is combined as a whole, and can reach various drawing effects easily, and its build is less, is convenient for carrying, and is very practical concerning the student.
Description of drawings:
Below in conjunction with description of drawings and embodiment the utility model is further specified
Accompanying drawing is the utility model front view
Wherein, 1-protractor, 2-45 ° right angle triangle, 3-a limit, 4-b limit, 5-rippled edge, 6-30 ° right angle triangle, 7-ruler
The specific embodiment:
In the embodiment shown in the figures, a kind of four unification chi dishes, it is characterized in that: it forms one by 2,30 ° of right angle triangles 6 of 1,45 ° of right angle triangles of protractor and ruler 7, the scale of described protractor 1 is 90, two groups of data are arranged up and down, summit, right angle with 45 ° of right angle triangles 2 during angulation is a starting point, and a limit 3 or b limit 4 are datum line; Described 30 ° of right angle triangles 6 are positioned at the right-hand member of 45 ° of right angle triangles 2, and the edge parallel with the hypotenuse of 30 ° of right angle triangles 6 is rippled edge 5; Described ruler 7 is positioned at the bottom of chi dish, and ruler 7 two ends are provided with corresponding parallel scale.
During measuring angle, angle is a datum line with b limit 4 between 0-90 ° the time, and the summit, right angle is that starting point can be measured the number of degrees at angle easily; Angle is a datum line with a limit 3 between 90 °-180 ° the time, and the summit, right angle is that starting point can be measured the number of degrees at this angle easily; When drawing the angle of 30 ° or 45 °, 30 ° of right angle triangles 6 and 45 ° of right angle triangles 2 just can conveniently draw respectively; When drawing wave, can easily draw along rippled edge 5; When drawing parallel lines, utilize ruler 7 straight line that draws, again with the parallel scale above the adjusting to a line ruler 7, the corresponding straight line that draws on ruler 7 limits then gets final product.
