Abstract

The invention discloses a designing major hand-operated drawing board. The designing major hand-operated drawing board comprises a drawing board body. First fixing frames are symmetrically distributedat the upper end of the back face of the drawing board body. Second fixing frames are movably connected with the first fixing frames through telescopic grooves. A fixedly connected connecting rod isarranged between the second fixing frames. An adjusting groove is formed in the connecting rod. Two first adjusting shafts are arranged in the middle of the adjusting groove. Each first adjusting shaft is provided with a first driving gear and a second driving gear. The first driving gears are engaged with each other. Second driven gears are connected with the adjacent second driving gears throughchains. The inner sides of the first fixing frames are provided with a rack engaged with the second driven gears. The connecting rod is provided with a fixing hole. The outer sides of the first adjusting shafts are provided with a rotary plate. A handle bar is arranged on the outer side of the rotary plate, an operator can directly rotate the rotary plate, the drawing board is adjusted to go up and down, and adjustment is quite convenient and quick.

Description

Technical field: [0001] The invention relates to a drawing board, in particular to a hand-operated drawing board for professional design. Background technique: [0002] Drawing board, that is, a flat plate that is often used to pad drawing paper in sketching and painting. It is often placed on the easel, and some are placed on the knee for drawing. Fix the drawing board on the easel, some use clips, and some use tape. The size of the drawing board depends on the user's requirements. Most of them are made of wood. In addition, there is a kind of plastic drawing board, which can not only draw directly on the board, but also can be wiped off. It is suitable for children's drawing practice, and it is often used in toys. [0003] Although the existing drawing boards can be used for height adjustment, the adjustment and use method is too complicated, the operation is cumbersome, and it is very troublesome. When the adjustment is used, it is easy to be pinched. Invention content...
