A drawing board is needed in the art design process; it is a flat surface commonly used to hold drawing paper in sketching and painting, usually placed on an easel. A search revealed a patent with application number 202021909797.4, which discloses a drawing board with a multi-angle adjustable structure for art design. The board includes a drawing board and a movable support column. The upper end of the drawing board has a female buckle with a female buckle inside. The lower end of the drawing board has a drawing board frame, and the rear end of the drawing board frame has a fixed support column. The rear end of the fixed support column has an iron plate with a rivet fixed to its outer side. The middle of the movable support column has an iron plate with a rivet fixed to its outer side. The lower end of the movable support column has a bolt. One side of the storage basket has a hook with a fixing rod fixed to its lower end, and the other end of the storage basket has a collar.

[0003] However, in actual use, the applicant found that the angle adjustment of the drawing board was done manually by the staff, who had to manually pull and adjust the position of the movable support based on their senses, and then lock the movable support with a fixing rod after adjustment. This made the angle adjustment of the drawing board inconvenient and inaccurate. Therefore, we propose an art design drawing board with a multi-angle adjustment structure. Utility Model Content

[0020] See also Figure 1-3 As shown, this utility model provides a technical solution:

[0021] A multi-angle adjustable art design board includes a support plate 1, a support frame 2 fixedly connected to the top of the support plate 1, a movable beam 6 slidably connected to the inner wall of the support frame 2, a lead screw 8 rotatably connected to the top of the support frame 2 via a bearing, the lower end of the lead screw 8 threaded through the middle of the movable beam 6, and an adjustment handle 81 fixedly installed at the upper end of the lead screw 8. Lower supports 11 are symmetrically fixedly installed on the top of the support plate 1 on the front side of the support frame 2, an art design board 3 is installed above the lower supports 11, and upper supports 31 are symmetrically installed at the bottom of the art design board 3. 31 is rotatably connected to two lower supports 11 via hinge shafts. The upper part of the art drawing board 3 is movably connected to the movable beam 6 via connecting rod 7. Lower connecting supports 61 are symmetrically arranged on the front side of the movable beam 6. Upper connecting supports 32 are fixedly arranged on the rear side wall of the upper part of the art drawing board 3. There are two connecting rods 7. The lower ends of the two connecting rods 7 are rotatably connected to the two lower connecting supports 61 via connecting shafts. The upper ends of the two connecting rods 7 are rotatably connected to the two upper connecting supports 32 via connecting shafts. By rotating the lead screw 8, the movable beam 6 is driven to slide along the groove opened on the inner wall of the support frame 2. The sliding mechanism, through the cooperation of the upper connecting support 32, the lower connecting support 61, and the connecting rod 7, allows the art board 3 to rotate around the lower hinge axis, enabling quick and precise adjustment of the art board 3's angle. The operation is convenient. A placement plate 4 is movably connected to the front of the support plate 1, and a handle is fixedly installed on the front of the placement plate 4. A base 5 is located below the support plate 1. During use, the art board is stably placed in the desired position using the support frame 2. Before starting the art design, the user can adjust the angle of the art board 3 according to the design requirements. During adjustment, the adjusting handle 81 can be manually rotated to drive the lead screw 8 to rotate. The rotation of the lead screw 8 can drive the movable beam 6 to slide along the guide groove opened on the inner wall of the support frame 2. At this time, through the cooperation of the upper connecting support 32, the lower connecting support 61 and the connecting rod 7, the art drawing board 3 can be driven to rotate around the lower hinge axis, so as to achieve quick and accurate adjustment of the angle of the art drawing board 3. When doing art design, the personnel can manually pull out the placement board 4 from the inside of the support plate 1 and place the art design tools such as paint trays and brushes on the top of the placement board 4.

[0022] Connecting posts 12 are fixedly installed at the four corners of the bottom of the support plate 1. The lower end of the connecting post 12 is movably inserted into the column groove opened at the top of the base 5. A screw 9 is rotatably connected to the center of the top of the support plate 1 via a bearing. The lower end of the screw 9 is threaded into the threaded hole opened at the top of the base 5. A brake handle 91 is fixedly installed at the upper end of the screw 9. By rotating the screw 9, the distance between the support plate 1 and the base 5 can be quickly adjusted along the connecting post 12, so that the height of the art drawing board 3 can be adjusted according to the needs, better adapting to art designers of different heights and body types. Before art design, the user can manually turn the brake handle 91 to drive the screw 9 to rotate. The rotation of the screw 9 can drive the support plate 1 to move along the connecting post 12, adjusting the distance between the support plate 1 and the base 5, so that the position and height of the art drawing board 3 can be quickly adjusted, thus better adapting to the body type of the user.

[0023] Working Principle: In use, the art design board is stably placed in the desired position using the support frame 2. Before starting the art design, the user can adjust the angle of the art design board 3 according to the design requirements. During adjustment, the adjustment handle 81 can be manually rotated to drive the lead screw 8 to rotate. The rotation of the lead screw 8 can drive the movable beam 6 to slide along the guide groove opened on the inner wall of the support frame 2. At this time, through the cooperation of the upper connecting support 32, the lower connecting support 61 and the connecting rod 7, the art design board 3 can be driven to rotate around the lower hinge axis, realizing the rotation of the art design board 3. The angle can be quickly and accurately adjusted. When doing art design, the user can manually pull the placement plate 4 out from the inside of the support plate 1 and place the art design tools such as paint trays and brushes on the placement plate 4. Before doing art design, the user can manually turn the brake handle 91 to drive the screw 9 to rotate. The rotation of the screw 9 can drive the support plate 1 to move along the connecting column 12 to adjust the distance between the support plate 1 and the base 5, so that the position and height of the art drawing board 3 can be quickly adjusted to better adapt to the user's body shape.
