Description

TECHNICAL FIELD

[0001] The utility model relates to drawing board technical field, concretely relates to a drawing board tool for children. BACKGROUND

[0002] The children drawing board is a drawing tool specially designed for children, which can not only stimulate children's interest in drawing, but also cultivate their creativity and imagination. During the use of the drawing board, children need to be guided to maintain correct sitting posture and pencil holding posture to avoid affecting their health due to long-term low head, bending, incorrect sitting posture and other factors, and to ensure the normal development of their bodies. At present, most drawing boards can adjust the correct sitting posture of children by adjusting the support angle, but during the drawing process, some patterns may be inclined, and the drawing board can usually only be rotated by 90° or 180°, making it difficult to rotate by other angles while ensuring that the drawing board is firmly fixed. Therefore, children usually need to tilt or twist their bodies to match the inclination angle of the pattern in order to draw the inclined pattern, which can easily affect the development of the spine, cervical vertebra and other parts of the children, and is not conducive to the cultivation of good sitting posture of children.

[0003] Based on the above situation, the Chinese patent with publication number CN221417802U discloses a portable drawing board, which comprises a drawing board, a first handle fixedly installed at the top end of the drawing board, a rear end plate hingedly connected to the rear side of the bottom end of the drawing board, a second handle fixedly installed at the top end of the rear end plate, a wiping assembly slidingly arranged on the upper side of the front end of the drawing board, an auxiliary line drawing assembly slidingly arranged on the lower side of the front end of the drawing board, and a support assembly arranged between the drawing board and the rear end plate. The support plate of the rear end plate opened by rotation can play the role of a support to ensure the stability of the drawing board during use and can adjust the support angle. However, the overall height of the drawing board cannot be adjusted, and when the height of the table on which the drawing board is placed is not suitable, the user cannot adjust the appropriate sitting posture by adjusting the height of the drawing board. In addition, when the drawing board needs to be rotated to draw an inclined pattern, the drawing board and the rear end plate need to be rotated simultaneously due to the hinged connection, and the drawing board cannot maintain a stable support angle through the support of the support plate. Therefore, the user needs to tilt or twist their body to match the inclination angle of the pattern to facilitate drawing the inclined pattern, which is not conducive to maintaining the correct sitting posture of the user. Therefore, there is still room for improvement of the drawing board. UTILITY MODEL CONTENT
