Description

Technical Field

[0001] The utility model relates to the technical field of folding drawing boards, in particular to a folding drawing board with both wall-hanging and mobile functions. Background Art

[0002] When painting large-scale paintings, calligraphers and painters need enough working area to accommodate the canvas or drawing board; standing or squatting in front of the canvas requires more physical strength and control, which will bring a certain burden to the body.

[0003] At present, when painting large-scale paintings, the drawing board is either placed flat or fixed vertically on the wall. When the drawing board is placed flat, it is not easy to see the normal proportion of the whole, and the painter needs to bend over to paint; when the drawing board is fixed to the wall, it is difficult to reach high places, and the painter needs to stand on a ladder to paint, and the painter needs to squat to paint low places. Therefore, the current methods will cause the painter to maintain uncomfortable body movements during the painting process to ensure the quality of the painting, which affects the painting technique and is very easy to get tired, making it impossible to persist in painting for a long time. The impact is even greater for some elderly calligraphers and painters; after the painting is completed, 3-4 people are needed to lift the painting together before the painting can be moved. Summary of the invention

[0004] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a folding drawing board with both wall-hanging and movable functions to solve the problem that the drawing board cannot be moved and changed to multiple angles according to the needs of the painter when painting large-scale paintings.
