Abstract

The utility model discloses a multi-functional protractor of simply drawing, mark, parallel interval scale marks, angle scale marks the constitution including transparent rigid material and the sharp scale of printing on it. The linear scale marks are arranged on the edge of the material, the parallel interval scale marks are perpendicular to the linear scale marks, and the angle scale marks are radially arranged by taking the middle point of the linear scale marks as the circle center. The various scale marks are superposed with the generatrix on the plane, so that the extension line, the vertical line, the parallel line and the specific included angle line of the generatrix can be drawn, and the positions and the lengths of the various line segments can be designated. Because the straight line scale marks, the parallel interval scale marks and the angle scale marks are placed on the same material through arrangement, the problems that the prior drawing needs various tools such as a ruler, a set square and a protractor, and the drawing process takes labor and time can be solved.

Description

Multifunctional Simple Cartography Protractor

technical field

The utility model relates to a tool for drawing geometric figures, in particular to a drawing tool for quickly drawing geometric figures which can draw extension lines, vertical lines, parallel lines and specific angle lines of a bus on a plane.

Background technique

Due to the needs of mapping, appropriate mapping tools are usually required. As shown in Figure 1, it is an existing linear drawing tool. The tool comprises a rigid material 10a on which scales 11a are printed. It can be used to draw a line segment of a specific length, and to extend a known line segment. However, it is not possible to integrate various required measurement tools comprehensively, and it is inconvenient to use.

A ruler is a straight edge of a hard material with a scale printed on it to draw a line segment of a specific length. However, when drawing general geometric figures, it is usually necessary to draw vertical lines of known generatrices, parallel lines with specific spacing, specific angled lines, etc., which cannot be drawn with existing rulers. Promptly use tools such as set squares, protractors, although the above-mentioned purpose can be achieved, it is inconvenient to carry and has the disadvantages of labor and time-consuming in the drawing process.

The purpose of the utility model is to provide a multi-functional simple drawing protractor.

For reaching above-mentioned purpose, the concrete content of the present utility model is:

A tool for drawing geometric figures, which is a ruler made of transparent hard material, which includes a linear scale mark printed on the edge of the material; it is also provided with parallel spaced scale marks, and the parallel spaced scale marks are the same as the straight line scale marks vertical.

Wherein the surface of the transparent hard material is additionally provided with an angle scale mark, and the angle scale mark takes a point marked by a straight line scale as the center of the circle in a radial shape.

Wherein the angle scale mark uses the midpoint marked by the straight line scale as the center of the radial circle.

Wherein the linear scale mark, the parallel spacing scale mark and the angle scale mark are printed layers attached to the transparent hard material.

The utility model also includes a tool for drawing geometric figures, which is a ruler made of transparent hard material, which includes a linear scale mark printed on the edge of the material; an angle scale mark is also provided, and the angle scale mark is marked with a straight line scale The marked point is the center of the circle radially.

Wherein the surface of the transparent hard material is printed with parallel spacing scale marks, and is perpendicular to the straight line scale marks.

Wherein the angle scale mark uses the midpoint marked by the straight line scale as the center of the radial circle.

Wherein the linear scale mark, the parallel spacing scale mark and the angle scale mark are printed layers attached to the transparent hard material.

The utility model integrates the functions of the existing ruler, triangular plate, protractor, etc., and is used to draw the extension line, vertical line, parallel line, specific angle line, etc. of the busbar through various scale marks on the transparent hard material, and then form a variety of geometric figures. Therefore, the trouble of changing tools can be reduced, and drawing steps can be reduced, effectively increasing drawing efficiency and accuracy.
