Portable drawing tool with functions of scroll holder and drawing board simultaneously

Abstract

The invention discloses a portable drawing tool with the functions of a scroll holder and a drawing board simultaneously. The portable drawing tool comprises a holder part arranged in the middle, an upper cover body arranged at the top end, and a lower cover body arranged at the bottom end. The upper cover body and the lower cover body are detachably connected with the ends of the holder part so as to form a containing cavity of the scroll holder. After the inner circumferential face of the holder part is unfolded, the holder part is of a flat plate structure and can serve as the drawing boardused for drawing. Compared with the prior art, the portable drawing tool has the advantages of being convenient to use, compact in size, light and convenient to carry and the like, the functions of the drawing board and the scroll holder can be switched conveniently, reliably and fast, and a user can use the portable drawing tool conveniently.

Description

Technical field [0001] The invention relates to the technical field of art painting tools, in particular to a portable painting tool with the function of a painting tube and drawing board. Background technique [0002] The drawing board and the drawing tube are the two tools that need to be used when going out to paint and sketch. These two tools are usually independent of each other, and the drawing board is usually a hard board and has a large area. When going out, carrying two objects at the same time will occupy a large space and inconvenient carry. [0003] In order to solve the above problems, the prior art optimizes and improves the above two items, optimizes and integrates the painting tube and the painting board into an integrated structure, so that the device or mechanism has both the function of the painting board and the painting tube, and finally makes the overall lighter and easier to switch. . [0004] However, the improvement scheme of the prior art still has many t...

AI Technical Summary

Problems solved by technology

[0004] However, there are still many technical defects in the improvement scheme of the existing technology. For example, Chinese patent 201710188408.X discloses a dual-purpose drawing board. Rib connection, the use of materials and structures is more complicated and inconvenient to use

Chinese patent CN201220689785.4 discloses a painting tube and drawing board integrated easy-to-carry painting tool. resulting in a more complex structure and ease of use

In addition, patent 201520706724.8 discloses a multi-purpose portable painting tube frame. The technical solution is a mechanism that integrates a painting tube, a drawing board, and a drawing board support frame, and the side drawing board can be folded into a rectangular painting tube mechanism. Rich in functions, but the structure is too complicated and the volume is too large to lose portability

There is also a Chinese patent 200620021098.X which discloses a composite painting tube drawing board. The patent consists of a plurality of flat plates closely arranged to form a flat board body, and a layer of flexible fabric connecting layer is bonded on the flat board. Through holes, and then the fastening screw is inserted into the through hole, and the fastening screw is equipped with a nut. This patented scheme uses the screw for fastening, which will generate a large weight

[0005] In summary, the existing technology integrates the drawing board and the painting tube into one structure, but usually there are problems such as the overall structure is too complicated, the operation process of function transformation is inconvenient, and it is not convenient to carry. Optimize the settings to make the device integrated with the functions of the painting tube and the drawing board more convenient to use, more compact and lighter to carry, etc.
