Combined type drawing device of ruler drawing board

Abstract

The invention relates to a combined type drawing device of a ruler drawing board. The combined type drawing device comprises a T-square, wherein the T-square is arranged on the drawing board and moves up and down along the two sides of the drawing board, a horizontal sliding chute is arranged in the middle of the T-square, an angle measure connecting board moves along the horizontal sliding chute, an angle gauge is arranged at the upper end of the angle measure connecting board, an angle square is connected with the angle gauge through an angle measure rotary shaft, a vertical sliding chute is arranged in one side of the angle square, one end of a supporting ruler moves along the vertical sliding chute, the other end of the supporting ruler is provided with a scriber and connected with one end of a rotating ruler, a pencil is arranged at the other end of the rotating ruler, and a compass is formed by the rotating ruler, the scriber and the pencil. The combined type drawing device combines the drawing board, the T-square, the angle square, the angle gauge, the compass and the like, horizontal lines, vertical lines, straight lines at different angles, circles and others can be drawn, and the drawing device is simple in structure, multifunctional, convenient to carry and capable of effectively improving drawing efficiency and guaranteeing drawing quality and capable of effectively reducing lose possibility.

Description

Technical field: [0001] The invention relates to a drawing tool, in particular to a ruler-compass drawing-board combined drawing device which combines drawing tools such as a drawing board, a T-square, a protractor, and a compass. Background technique: [0002] At present, the commonly used manual drawing tools include ruler, set square, T-square, square, protractor, compasses, horizontal angle ruler, etc., because the structures of each drawing tool are different, and their functions are relatively single, multiple drawings are required for manual drawing Only when the tools cooperate with each other can the drawing task be completed, especially when drawing complex graphics, each drawing tool needs to cooperate with each other and use them alternately. During the drawing process, many auxiliary steps need to be done, and many drawing marks are left on the drawing. , the operation is cumbersome, and the drawing marks are easy to be confused, which leads to drawing errors ...

AI Technical Summary

Problems solved by technology

[0002]At present, the commonly used manual drawing tools include ruler, set square, T-square, square, protractor, compass, horizontal angle ruler, etc., because the structures of each drawing tool are different, Moreover, its function is relatively single. When doing manual drawing, multiple drawing tools need to cooperate with each other to complete the drawing task. Especially when drawing complex graphics, each drawing tool needs to cooperate with each other and use them alternately. Many auxiliary steps leave a lot of drawing marks on the drawing, which is cumbersome to operate, and the drawing marks are easy to be confused, which leads to drawing errors and needs to be re-modified, resulting in unclean drawing, affecting the efficiency of drawing, and the cleanliness of the drawing , and too many marks on the drawing surface will also affect the accuracy of the drawing, leading to an increase in the drawing error and seriously affecting the quality of the drawing. In addition, when drawing, the drawing personnel should use one hand to hold down the drawing tools such as the T-square, the set square, and the other A hand holding a pencil to draw a line, scrambling

When drawing, you need to carry multiple drawing tools. The drawing tools are wide and narrow, different in length, and uneven. It is very inconvenient to carry. A large number of drawing tools may be lost or missed.
