High-practicability ruler for product design drawing

Abstract

The invention relates to the technical field of drawing rulers, and discloses a high-practicability ruler for product design drawing. The ruler comprises a drawing ruler body, a drawing disc, a drawing auxiliary line and a protractor, and the drawing disc is located at the left side of the front surface of the drawing ruler body and fixedly connected with the drawing ruler body; and a drawing auxiliary line is arranged on the front surface of the drawing ruler body, the protractor penetrates through the right side wall of the drawing ruler body, and the protractor is fixedly connected with a protractor sliding block. By arranging a drawing disc fixing base, a user can press the drawing disc fixing base by hand to rotate the drawing disc and the drawing ruler body, a drawing pen is insertedinto a circle drawing auxiliary groove formed in the drawing disc to draw a circle, and by arranging the drawing auxiliary line, a horizontal drawing groove, a horizontal drawing sub-groove, a vertical drawing groove and a vertical drawing sub-groove which are formed inside can be used for drawing parallel lines or vertical lines of the related sizes for product design and use.

Description

technical field [0001] The invention relates to the technical field of drawing rulers, in particular to a highly practical drawing ruler for product design. Background technique [0002] Drawing ruler is a common tool for drawing geometric figures and product design drawings. In product design, it is used together with other drawing tools to carry out product design drawing. The drawing ruler is mainly used to draw straight lines on the drawing board, or cooperate with the settable to draw straight lines in other directions. Other common drawing utensils include drawing boards, compasses, and T-squares. [0003] Drawing rulers are often used in product design and drawing. Traditional drawing rulers are mostly used for single-drawing straight lines, which have single functions and poor practicability. The edge layer is relatively thin. During use, if it is accidentally dropped and bumped, it will easily cause cracking and damage, which will affect the subsequent use of the ...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a highly practical product design and drawing ruler, which solves the problem that the traditional drawing ruler is mostly used for single drawing of a straight line, has single functionality and poor practicability, and cannot meet the needs of different product design and drawing. The demand also limits the use of the drawing ruler, and the edge layer of the drawing ruler is thin. During use, if it is accidentally dropped and bumped, it will easily cause cracking and damage, which will affect the subsequent use of the drawing ruler.
