Multifunctional table for mechanical drawing

Abstract

The invention provides a multifunctional table for mechanical drawing, which comprises a support, a supporting plate, a supporting assembly, a plurality of first elastic line and a plurality of second elastic line, the supporting plate, the supporting assembly, the first elastic lines and the second elastic line are arranged on the support in a pivoted mode, and the supporting assembly comprises a supporting piece arranged on the back face of the supporting plate in a pivoted mode and a plurality of positioning parts arranged on the support. The bottom end of the supporting piece can be inserted into one positioning part, the first elastic lines are vertically connected between the upper side and the lower side of the supporting plate, and the first elastic lines are arranged in the length direction of the supporting plate at intervals; the second elastic lines are transversely connected between the left side and the right side of the supporting plate, and the second elastic lines are arranged in the width direction of the supporting plate at intervals. According to the multifunctional table for mechanical drawing, through orthogonal arrangement of the first elastic lines and the second elastic lines, drawing paper can be divided into a plurality of drawing areas, so that an auxiliary effect is achieved when students manually and mechanically draw, and the drawing effect is better.

Description

technical field [0001] The invention relates to the technical field of teaching aids for mechanical drawing, in particular to a multifunctional table for mechanical drawing. Background technique [0002] Mechanical drawing is a subject. Manual mechanical drawing is a skill that students of this major must master. When doing manual mechanical drawing, sometimes students need to draw without drawing tools such as rulers and compasses. But because the drawing paper is blank, it is more difficult for students who just learn to draw if they draw directly. [0003] In addition, when drawing mechanically, it is usually necessary to spread the drawing paper on the drawing board, and then use adhesive tape to glue and fix the drawing paper. During the drawing process, students tend to lose their enthusiasm for learning due to lack of assistance. In order to improve the effect of drawing, generally students will use a pencil to draw lines on blank drawing paper, and then erase the dr...

Problems solved by technology

After repeated rubbing with an eraser, it is not only prone to local fading, which affects the overall appearance, but also, due to the existence of the background color, when the line drawn by the pencil is relatively shallow, it will also affect the clarity of the drawing, thereby affecting the effect of the drawing
