Auxiliary adjusting device for drawing

Abstract

The invention discloses a auxiliary adjusting device for drawing, which is characterized by comprising an upper plate and a lower plate which are overlapped, wherein the rear ends of the upper and lower plates are rotationally connected through a rotating shaft; the lower plate is provided with a tabletop fixing mechanism for fixing the lower plate to a tabletop; the front ends of the upper and lower pates are provided with an angle adjusting device capable of adjusting the opening angles of the upper and lower plates; and the side face of the upper plate is provided with a T-square locating mechanism for locating a T-square and a T-square moving mechanism for quantitatively moving the T-square. The device is used for drawing, and can conveniently and quickly adjust drawing angles and quantitatively move the T-square, and therefore, the figure degree of a map maker is reduced, and the drawing efficiency is improved. In addition, the device has the advantage of convenient, flexible and quick adjustment.

Description

technical field [0001] The invention relates to a drawing device, in particular to a drawing auxiliary adjusting device. Background technique [0002] In the field of artistic creation and engineering drawing, it is often necessary to use drawing tools to assist drawing. Common drawing tools, including T-square, drawing table, etc. [0003] Although the popular drafting tables on the market can be tilted at a certain angle, the T-square becomes difficult to control after being tilted at a certain angle, and a slight movement will make it crooked and cause a large error. This function is often not practical for most students. How to make the drawing board have a tilting angle that makes the drawing person comfortable and the T-square can slide freely and accurately has become a problem to be solved urgently. The Chinese utility model patent mechanical drawing drawing board (application number: 201220312606) with the application date of July 2, 2012 discloses a mechanical d...

AI Technical Summary

Problems solved by technology

This new type of use standardizes the placement of various tools and improves the efficiency of drawing to a certain extent, but it cannot change the tilt angle of the drawing board itself

Moreover, although the movement of the T-square is free, it cannot be quantified, which does not greatly improve the efficiency of the drawing process.
