Description

Technical Field

[0001] The utility model relates to the technical field of art drawing boards, in particular to a foldable and portable art drawing board. Background Art

[0002] In order to ensure stability and flatness during painting, art boards are mostly made of wood, metal or thick plastic. Although these materials are durable, they directly lead to the problem of large size and heavy weight of the board. In addition, its fixed integrated design makes the board occupy a considerable storage space when not in use, which is difficult to meet the needs of modern artists for portability and space economy. Especially in occasions where the creation location needs to be changed frequently, such as outdoor sketching, travel creation, etc., the transportation of traditional drawing boards becomes a challenge in terms of physical strength and space management.

[0003] As art creation moves from indoors to outdoors, the diversity of environments places higher demands on the portability of drawing boards. Traditional non-foldable drawing boards have greatly reduced their flexibility in application when faced with narrow spaces (such as in train compartments, corners of crowded cafes) or special terrains (mountains, beaches). Artists have to compromise between their desire to create and the difficulty of carrying them, and sometimes even give up many moments of inspiration. In addition, the protection and transportation issues under severe weather conditions are also a major weakness of traditional drawing boards. The inability to fold and store means that they are more susceptible to damage, which limits the freedom and safety of creation.

[0004] The inconvenience of traditional art drawing boards indirectly affects the artist's creative efficiency and overall experience. When the creative scene needs to be changed quickly, the time loss caused by the inconvenience of carrying may miss the best creative opportunity or affect the continuity of creation. At the same time, the bulky drawing board increases the physical burden of the painter. Carrying it for a long time may cause physical fatigue, affect the concentration and touch of the creation, which is undoubtedly a major obstacle for artistic creation that pursues the instant capture and expression of inspiration.

[0005] Therefore, how to provide a foldable and portable art drawing board is a problem that those skilled in the art need to solve urgently. Utility Model Content
