Description

Technical Field

[0001] The utility model relates to the technical field of painting tools, in particular to a drawing board. Background Art

[0002] An art board is a flat surface used to support drawing paper. It's often placed on an easel, but some people use it on their knees. It's secured to the easel with clips or tape. The size of the board varies depending on the user's needs. Most boards are made of wood and have a light, smooth feel. They're available at art supply stores.

[0003] In order to fix the drawing paper, existing art drawing boards will add a fixing structure on the board surface. For example, the drawing board that can fix the drawing paper disclosed in announcement number CN221660496U can form a set of reverse elastic structures by setting a metal pressure strip, a hollow ring, a reset rod and a reset spring, which makes it convenient to press the metal pressure strip tightly against the top surface of the drawing board.

[0004] However, in the above solution, the metal pressure strips, limit plates and other structures all protrude from the surface of the drawing board. When the user draws to the edge of the drawing paper, the protruding structural components will cause obstacles to the user and affect the painting.

[0005] So we propose a drawing board to solve the problems raised above. Utility Model Content

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] See also Figure 1-7 As shown, the utility model provides a drawing board, including a board body 1, a clamping plate 2 is rotatably installed on the top of the board surface of the board body 1 through a torsion spring 7, and paper jam slots 3 for drawing paper to be inserted on both sides are opened on both sides of the board surface of the board body 1. The paper jam slots 3 are through slots, which extend along the length direction of the board body 1. The paper jam slots 3 divide the board body 1 into a main board 11 located in the middle and side boards 12 located on both sides. A fixing mechanism 4 for clamping the drawing paper is provided in each of the two side boards 12.

[0030] like Figure 2-4 As shown, the fixing mechanism 4 includes a clamping block 42 and a handle 45. A sliding groove 41 is provided on the side of the side panel 12 close to the paper jam slot 3, and is slidably connected to the clamping block 42. A first magnetic strip 43 is embedded on both sides of the main board 11. A second magnetic strip 44 adsorbed on the first magnetic strip 43 is embedded on the side of the clamping block 42 close to the paper jam slot 3. The handle 45 is a U-shaped structure and is located on the outside of the side panel 12. Both ends of the handle 45 pass through the side panel 12 and extend into the sliding groove 41 and are fixed to the side wall of the clamping block 42.

[0031] When fixing the drawing paper, first spread the drawing paper flat on the main board 11, then pull the handle 45 to retract the clamping block 42 into the slide groove 41, then insert the two sides of the drawing paper into the paper jam slot 3, release the handle 45, and the clamping block 42 will fit together under the magnetic attraction of the first magnetic strip 43 and the second magnetic strip 44 to clamp and fix the paper. Since the fixing mechanism is located inside the board body 1, it will not protrude from the board surface, so as to avoid hindering the user's drawing.

[0032] As a preferred technical solution of the present invention: Figure 1 、 5As shown in Figure 6, a smoothing mechanism 5 is also provided on the plate body 1, and the smoothing mechanism 5 includes a smoothing plate 51 slidably mounted on the plate surface of the plate body 1 and an adjusting rod 52 slidably mounted on both sides of the side plate 12. A limiting ring 55 is fixed to the bottom of the adjusting rod 52, and the diameter of the limiting ring 55 is larger than the diameter of the adjusting rod 52. A guide groove 56 adapted to the limiting ring 55 and the adjusting rod 52 is provided on the top of the side plate 12. The guide groove 56 extends in the length direction of the plate body 1, and an extension plate 53 is fixed on the adjusting rod 52. The adjusting rod 52 is slidably connected to the smoothing plate 51. A compression spring 54 is provided between the bottom wall of the extension plate 53 and the top wall of the smoothing plate 51. The compression spring 54 is sleeved on the outside of the adjusting rod 52, and a lifting plate 6 is provided on the top of the extension plate 53.

[0033] Before securing the drawing paper, lift the smoothing plate 51 upward using the lifting plate 6, leaving a gap between it and the main board 11. The drawing paper is then laid flat on the main board 11, and the upper portion of the drawing paper is passed through the gap and clamped by the clamping plate 2. The lifting plate 6 is then released, and the smoothing plate 51, under the action of the compression spring 54, compresses the drawing paper. The smoothing plate 51 is then moved downward to smooth the paper and then compressed. If the smoothing plate 51 is located below the board and becomes an obstruction to the user, it can be moved upward.
