The invention provides a scroll holder for art design drawing, and relates to the related field of art design. An inner groove is formed in the bottom of a scroll holder body, and a hollow latex seatis connected to the inner side of the inner grove in a bonding mode through a bonding layer; a unidirectional air guiding valve is mounted at the position of an air inlet of the hollow latex seat, andan exhaust pipe is fixedly mounted at the position of an air outlet of the hollow latex seat; the tail end of the exhaust pipe penetrates through the bottom of the scroll holder body and extends to an inner cavity of the scroll holder body, and an air-tight core is mounted on the exhaust pipe; a storage groove is formed in the bottom of the left side of the scroll holder body, and the tail end ofthe air-tight core penetrates through the inner side wall of the scroll holder body and extends to the inner side of the storage groove. According to the scroll holder for the art design drawing, thethinner inner side edge and a contact protrusion of an inner arc air bag are mutually matched to downward rub and press drawing paper placed in the inner cavity of the scroll holder body, so that thecondition that rim angles of the drawing paper placed in the scroll holder body are damaged due to the fact that the drawing paper is subjected to jolt to pitch is prevented, and thus the purpose ofprotecting the drawing paper is achieved.
Description
Technical field [0001] The invention relates to the technical field related to art design, in particular to a painting tube for art design drawing. Background technique [0002] Art painting often goes to the field to sketch. After the designer draws it, he rolls up the drawing and puts it in the painting tube. The existing painting tube is generally a fixed internal structure and generally not adjustable. For the finished product with smaller drawing paper, it is placed in the painting tube. The bumps in the field easily make the internal drawing paper bumps, causing damage to the edges and corners of the drawing paper. This is not allowed by the designer, and it is also not conducive to the long-term preservation of the drawing paper. Therefore, a drawing tube can be used for it. The internal drawing paper is softly positioned to ensure the integrity of the drawing paper. Summary of the invention [0003] It solves the problem that the existing drawing tube cannot be softly pos...
