[Background technology]

[0002] Art drawing equipment is a basic tool for artistic creation, and the sketching board is one of the art drawing equipment. The sketching board is a core tool for outdoor sketching or mobile creation, mainly used to fix the drawing paper or canvas, facilitate the use and carrying of drawing materials, and provide a stable drawing surface.

[0003] Common sketching boards currently available on the market typically consist of a thin wooden board or a board made of acrylic or plastic, with simple metal clips to secure the drawing paper. These types of sketching boards are limited to a single drawing format, such as sketching or drawing. While suitable for handheld use, they are unable to meet the diverse needs of drawing, sketching, watercolor, gouache, and other media. Furthermore, their large size makes them inconvenient to carry during daily commutes or outings, and it is difficult to carry multiple drawing materials at the same time. Carrying drawing materials requires a separate ink holder, placing a psychological and physical burden on artists who sketch on the go. To address these issues, the inventors propose a portable drawing board. Summary of the Invention [Problem to be solved by the invention]

[0013] The following will clearly and completely describe the technical solutions in the embodiments of the present invention, in conjunction with the drawings of the embodiments of the present invention. Obviously, the described embodiments are not all embodiments, but only some embodiments of the present invention. Needless to say, any other embodiments that a person skilled in the art can obtain based on the embodiments of the present invention without any creative ingenuity will fall within the scope of the claims of the present invention. [Example]

[0014] As shown in FIGS. 1 to 5, the portable drawing board includes a drawing board main body 1, a double-sided drawing board 5, and a modular paint tray 9. The drawing board main body 1 and the modular paint tray 9 are provided at both ends of the double-sided drawing board 5. A plurality of engagement slots 2 are provided on both sides and one end of the drawing board main body 1, and ring binder attachment holes 3 are provided symmetrically on the drawing board main body 1. An asymmetrical rotation shaft hole 4 is provided symmetrically on one end of the drawing board main body 1 away from the engagement slots 2. A drawing board rotation shaft hole 7 is provided at one end of the double-sided drawing board 5 closer to the drawing board main body 1, at a position overlapping with the rotation shaft hole. A plurality of drawing board slots 2 (8) are provided symmetrically across the width of the double-sided drawing board 5, and a plurality of drawing board slots 1 (6) are provided symmetrically across the length of the double-sided drawing board 5. A paint tray fixing insert 13 is symmetrically provided at one end of the modular paint tray 9 near the double-sided drawing board 5, and the paint tray fixing insert 13 is inserted into drawing board slot 2 (8) of the double-sided drawing board 5. The paint tray fixing insert 13 has a paint tray insert hanging hole 14. The modular paint tray 9 is provided with multiple watercolor paint tanks 11, and a toning tank 12 is provided on one side away from the watercolor paint tanks 11. Magnet mounting holes 10 are provided at the four corners and in the center of the top surface of the modular paint tray 9, and neodymium magnets can be inserted into the magnet mounting holes 10. The paint tray fixing insert 13 forms a detachable connection with engagement slot 2, drawing board slot 1 (6), and drawing board slot 2 (8). The ring binder mounting hole 3 is used to attach a ring binder, which is convenient for securing drawing paper during drawing.

[0015] The top and bottom of the asymmetrical shaft hole 4 have a first mating surface with a 90° right angle and a second mating surface with a rounded arc corner. When the first mating surface is unfolded 180°, it abuts and locks with the right-angled surface of the double-sided drawing board 5. When folded 90°, the rounded surface of the second mating surface slides and fits.

[0016] By providing first and second mating surfaces in the asymmetrical rotation shaft hole 4 of the drawing board main body 1, the drawing board main body 1 and the double-sided drawing board 5 can be opened and closed at 90 degrees. When both parts are unfolded flat, they are fixed at a 180-degree angle and cannot bend outward any further. Folding the drawing board inward at 90 degrees not only makes it easier for artists to store, but also allows the drawing board to be inverted using this included angle, tilting the drawing board surface, allowing artists to draw while sitting at a desk and providing an angle that is beneficial to neck health. When unfolded flat outward and fixed at 180 degrees, the artist can draw on a stationary, flat surface.

[0017] The engagement slots 2, drawing board slot 1 (6), and drawing board slot 2 (8) of the drawing board main body 1 and double-sided drawing board 5 are used to attach a modular paint tray 9. The modular paint tray 9 can be inserted into any slotted position via the paint tray fixing insert 13, allowing the artist to freely adjust the installation position according to their dominant hand habits and the arrangement of their drawing supplies. This drawing board also allows the artist to independently attach any drawing tool with an insert piece, satisfying the artist's needs of both holding it in their hand and leaving it on a desk, and is compact and easy to carry.

[0018] After attaching the ring binder to the ring binder attachment hole 3 of the drawing board body 1, the modular paint tray 9 of the drawing accessory can be removed, and the paint tray insert piece hanging hole 14 of the modular paint tray 9 can be attached to the ring binder.

[0019] When working, the three parts, the drawing board main body 1, the double-sided drawing board 5, and the modular paint tray 9, must be combined and used. Among them, the drawing board main body 1 and the double-sided drawing board 5 need to be fixed to each other via the asymmetrical rotation axis hole 4 using two iron rods with a diameter of approximately 2 mm as rotation axes, which are inserted into the asymmetrical rotation axis hole 4 of the drawing board main body 1 and the drawing board rotation axis hole 7 of the double-sided drawing board 5. The modular paint tray 9 is a flexible accessory tool, and the modular paint tray 9 can be attached to either the attached slots of the drawing board main body 1 or the double-sided drawing board 5.

[0020] When used on a desk, the drawing board main body 1 and the double-sided drawing board 5 form a 90-degree angle when closed, and the double-sided drawing board 5 can be placed face up on the desk. The modular paint tray 9 is attached to the drawing board slot 2 (8) of the double-sided drawing board 5. When drawing is finished, the modular paint tray 9 can be placed in a ring binder for easy transport. The drawing board main body 1 and the double-sided drawing board 5 can be used or carried flat when unfolded. Additionally, a ring binder attached to the ring binder mounting holes 3 can be used to carry tools such as drawing paper, a pen holder with round holes, and a brush cleaner. A cover can also be attached to the ring binder to cover the drawing tools and then tied with an elastic band.

[0021] The description of the orientation and relative positional relationships of the structures in this utility model, such as front, back, left, right, up and down, does not constitute any limitation on this utility model, but is merely for ease of description.
