Drawing board table capable of adjusting height and angle

Abstract

The invention relates to the technical field of lifting, and discloses a drawing board table capable of adjusting height and angle. The drawing board table comprises a base, a support column is fixedly connected to the upper portion of the base, and a sleeve rod is fixedly connected to the upper portion of the base. The adjusting process comprises the following steps of screwing knob and the limiting rod rotates with the knob, pulling-out, the feet are adjusted to the appropriate height, the limiting rod is inserted into the through hole, reverse rotating and the feet are stabled, treading pedal, downing the connecting rod, compressing the spring, the first piston is moved downwards, air in the first compression cylinder is discharged and enters the second compression cylinder through thehose to push the second piston, the telescopic rod moves forward to move the lower part of the base plate, the inclination angle of the base plate is reduced, the valve is closed when the drawing board table is adjusted to a proper position, the foot is loosened, the pedal returns to the initial position, when the inclination angle of the base plate needs to be increased, the one-way valve is opened, the air is scattered out, the proper position is adjusted and then the one-way valve is closed, and each person can adjust the position of the drawing plate according to the own requirements before drawing.

Description

technical field [0001] The invention relates to the technical field of lifting, in particular to a drawing board table whose height and angle can be adjusted. Background technique [0002] The drawing board refers to the flat plate used to pad the drawing paper when drawing. Generally, it takes a long time to draw a complete picture, ranging from a few hours to a few days or even years. Therefore, when drawing, the drawing The comfort of personnel is of paramount importance. [0003] Existing drawing boards are generally in the shape of a tripod, and the drawing boards are fixed by three brackets, but the structure of this kind of drawing boards is too simple to change the angle and height of the drawing boards during the painting process, and different painters have age differences, and different ages also It will lead to differences in height, so the existing drawing boards cannot meet the needs of people of different age groups. On the other hand, because the angle of th...

Problems solved by technology

[0003] Existing drawing boards are generally in the shape of a tripod, and the drawing boards are fixed by three brackets, but the structure of this kind of drawing boards is too simple to change the angle and height of the drawing boards during the painting process, and different painters have age differences, and different ages also It will lead to differences in height, so the existing drawing boards cannot meet the needs of people of different age groups. On the other hand, because the angle of the drawing board is fixed, people cannot adjust the drawing board to a suitable angle during the painting process, and need to keep their heads down for a long time The posture of bending over or raising the head leads to irregular painting postures, which will bring strong discomfort to the long-term painting process in the later stage. In the long run, it will increase the pressure on the shoulders, neck and other positions of the painters, which is not conducive to physical fitness. healthy
