Description

Drawing board table with adjustable height and angle

Technical Field

The invention relates to the technical field of lifting, in particular to a drawing board table with adjustable height and angle.

Background

The drawing board refers to a flat board used for padding drawing paper when drawing is carried out, generally, a complete drawing needs to be drawn for a long time, as little as several hours, as much as several days or even several years, and therefore, the comfort of a painter is particularly important when drawing is carried out.

The existing drawing board is generally in a triangular frame shape, the drawing board is fixed through three supports, the structure of the drawing board is too simple, the angle and the height of the drawing board in the drawing process cannot be changed, different drawing personnel have age differences, different ages also can lead to height differences, so the requirements of people in different age groups cannot be met by the existing drawing board, on the other hand, the angle of the drawing board is fixed, people cannot adjust the drawing board to be a proper angle in the drawing process, the people need to keep the posture of bending the head or bending the head upwards for a long time, the drawing posture is not standard, strong uncomfortable feeling is brought to the long-time drawing process in the later stage, the pressure of shoulders, the neck and other positions of the drawing personnel can be increased for a long time, and the health is not facilitated.

In order to solve the above problems, the inventor proposes a height and angle adjustable drawing board table, which has the advantage of automatically adjusting the height and angle of the drawing board through lifting, so that the height and angle adjustable drawing board table can ensure that a painter can adjust the height and angle according to the self requirement in the drawing process, can meet the requirements of people at different ages for use, can keep a comfortable posture for drawing, simultaneously relieves the uncomfortable feeling of the body, and increases the practicability and practicability of the device.
