Description

Technical Field

[0001] This utility model relates to the field of drawing tablet technology, specifically a retractable drawing tablet. Background Technology

[0002] Visual communication design drawing tablets have a simple structure, but their drawing surfaces are exposed to the external environment for extended periods, making them prone to scratches and wear.

[0003] A search of Chinese patent CN216579957U reveals a retractable drawing tablet for visual communication design. This improved tablet unfolds and retracts, effectively overcoming the shortcomings of traditional drawing tablets where the drawing surface is easily scratched from prolonged exposure to the external environment. It provides effective protection for the drawing surface, offering dust and dirt resistance with a high protection factor. The retractable tablet body can extend and retract within the protective cover using a sliding rod and sliding groove, facilitating its unfolding and retraction. Furthermore, the limiting screw, limiting screw groove, and limiting screw hole ensure a mechanical lock between the retractable tablet body and the protective cover after retraction, providing greater stability and reliability and effectively preventing automatic unfolding and detachment.

[0004] Based on the above search and existing technology, it was found that the above patent has certain defects. The retractable drawing tablet still needs a limiting structure to fix it, which is cumbersome and time-consuming. In addition, it cannot be folded with the storage and protective structure when pulled out, which takes up a lot of space. The ink needed for drawing is easily lost, which reduces the efficiency of the retractable drawing tablet. Utility Model Content
