Problems solved by technology

Most of the compasses currently used are conventional metal, plastic structures or fixed-size circles on templates, and there are also circles drawn with strings, etc. There is a problem that the center of a circle drawn with conventional compasses on thin paper is often punctured by the compass needle. Easy to misalign when drawing a circle

example 1

[0028] Example 1 draws a circle: there are some small circular holes in the compass area (16) in the circular movable template (2), which are arranged in four rows and are distributed at different distances from the center of the circle. Insert the circle with a pencil or a pen or other pens. Drive the circular movable template (2) in the hole to turn one or more circles to draw a circle or circles with different diameters, such as circles with a diameter of 10 mm, 11 mm, 12 mm and n mm, and circles with a diameter less than 10 mm Draw with fixed round hole (24).

example 2

[0029] Example 2 draws a triangle: a straight line (17), a straight line (18), a straight line (19) and a straight line (20) are arranged in the circular movable template (2), and one end of the straight line (20) is the center of circle, and the other end is connected to the projection (10) The arrows (14) on the top form a straight line, such as drawing an arbitrary right-angled triangle, first rotate the circular movable template (2) with the arrow (14) on the scale 90 degrees corresponding to the 360-degree scale (5) of the circumference, on the straight line (17) Draw an adjacent sideline, one end of the adjacent sideline is on the center line, rotate the circular movable template (2) on the scale 180 degrees of the arrow (14) corresponding to the circumference 360 ​​degree scale (5), draw the opposite sideline with a straight line (20), Rotate the circular movable template (2) again and draw the hypotenuse line with the straight line (20).

example 3

[0030] Example 3 to draw a triangle: If the length of the adjacent side and the angle between the adjacent side and the hypotenuse are known, first draw the opposite side line with a straight line (20), and then the arrow (14) corresponds to the angle required by the 360-degree scale (5) of the circumference On the scale, use straight line (20) to draw hypotenuse line, finally get final product with straight line (17) or upper scale (6) to draw adjacent side line, can draw each the desired triangle.

Abstract

The invention discloses a universal compass intelligent drawing template, and relates to a drawing tool. A round movable template body is rotated in a fixed template body. A plurality of round holes are formed in a compass area in the round movable template body and distributed in positions with different distances away from the circle center. One circle or a plurality of circles of different diameters can be drawn just by inserting a pencil or a ball-point pen into the round holes to drive the round movable template body to rotate by one circle or a plurality of circles. Symbol figures of triangles, squares, pentagons, diodes, audions, inductance coils and the like can be drawn just by adoption of straight lines, angular lines and patterns in the round movable template body. Various required figures can be drawn by means of intelligence of a drawer according to functions of the universal compass intelligent drawing template. The drawing tool can be widely applied to schools, factories, scientific and technology industries and the like; the universal compass intelligent drawing template is simple in structure and exquisite in size, and can be used conveniently by students, required patterns can be drawn through thinking by means of intelligence of the students, the initiative of the students can be achieved and exercised, and the abilities of problem analyzing and solving can be fostered.

Description

[0001] Technical field: [0002] The invention relates to a drawing tool, in particular to a universal compasses intellectual drawing template. [0003] technical background: [0004] Drawing tools are widely used in schools, factories, science and technology and other industries. Drawing tools have always played an indispensable role in the field of science and technology, especially for primary and middle school students with a population of hundreds of millions. Most of the compasses currently used are conventional metal, plastic structures or fixed-size circles on templates, and there are also circles drawn with strings, etc. There is a problem that the center of a circle drawn with conventional compasses on thin paper is often punctured by the compass needle. It is easy to misalign when drawing a circle. [0005] Invention content: [0006] The purpose of the present invention is to invent a kind of omnipotent compasses intellectual drawing template for above-mentioned d...
