Description

Technical Field

[0001] The utility model relates to the technical field of educational tools, and more particularly to a foldable drawing board for education. Background Art

[0002] In the existing technology, there are some limitations in the design and application of educational foldable drawing boards, which may affect the use effect and maintenance convenience of the drawing boards.

[0003] First, the drawing board in the prior art is usually designed with a fixed structure, and the angle of the drawing board cannot be flexibly adjusted. This design limits the flexibility of the drawing board and cannot be adjusted according to different painting postures and lighting conditions. For example, when painting outdoors, it may be necessary to adjust the drawing board according to the angle of the sunlight for better observation and painting. The fixed structure design makes such adjustment difficult, affecting the painting experience and teaching quality.

[0004] Secondly, the surface of the drawing board may be stained with paint after long-term use, and may be stained with dust when placed. In addition, the surface of the drawing board may be damaged after long-term use, such as scratches and wear. These problems involve the disassembly, cleaning or replacement of the drawing board. However, most drawing boards in the existing technology are fixed in structure and cannot be disassembled, resulting in the replacement of the entire device. This not only increases maintenance costs, but also may waste resources due to replacing the entire device.

[0005] In addition, although some devices use some devices to achieve quick replacement or disassembly and cleaning of the drawing board, their structure is relatively simple, resulting in low stability of the fixed part. During use, the drawing board is prone to loosening or even falling off, causing the drawing board to shift or even fall, affecting the use effect. This instability not only affects the painting experience, but may also cause harm to the user. Utility Model Content
