Drawing board

Abstract

The invention discloses a drawing board, which is capable of ensuring drawing quality and has higher drawing efficiency. The drawing board disclosed by the invention comprises a board, a transverse ruler and a straight scale; the transverse ruler is positioned on the board and in sliding fit with the board; a sliding groove is arranged on the transverse ruler; idler wheels are arranged at two ends below the transverse ruler; the idler wheels are in sliding fit with two lateral edges of the board; a sliding ruler is positioned on the transverse ruler; a sliding block below the sliding ruler is embedded in the sliding groove and in sliding fit with the sliding groove; a vertical ruler is positioned below a connection plate and articulated with the connection plate into a whole; two bolts are arranged below the connection plate; the bolts and two bolt holes on the sliding ruler are in corresponding insertion fit; and all of the straight scale, the transverse ruler and the sliding ruler are provided with scales and scale values. According to the drawing board disclosed by the invention, the transverse ruler always can vertically slide and be located on the board in a horizontal state; the vertical ruler can transversely slide to draw through the sliding ruler; in the need of drawing an inclined line, the vertical ruler is only necessary to rotate to a required position; the drawing board is simple to operate in the drawing process; the drawing speed is rapid; and the drawing quality is also high.

Description

technical field [0001] The invention relates to a drawing tool. Background technique [0002] At present, with the increasing abundance of computer graphics software, a large number of two-dimensional and three-dimensional graphics software has been popularized. However, in some places with poor conditions or special circumstances, the traditional drawing board method is still used. Straightedge, T-square, etc. are the basic tools for drawing. In the process of use, the above tools should be used frequently to draw various graph lines. Therefore, when drawing horizontal lines, vertical lines, and oblique lines, it is all done by sliding the ruler Alignment, after aligning, hold the ruler with your hands to prevent sliding and misalignment. You often feel that your hands are not enough, and mistakes often occur, resulting in poor quality of the drawn pictures and low drawing efficiency.
