Learning chair folding structure

Abstract

This utility model discloses a folding structure for a study chair, including a folding chair assembly and a folding tabletop assembly. The folding chair assembly includes a backrest support, rear legs that movably cooperate with the backrest support, and a support plate that movably cooperates with the rear legs. The folding tabletop assembly includes hollow armrests that movably cooperate with the backrest support, hollow sleeves that movably cooperate with the hollow armrests, and a retractable plate that movably cooperates with the hollow sleeves. This utility model uses limiting blocks to support the support plate. When unfolded, the bottom of the backrest support and rear legs rests on the ground, maintaining stability. The slotted plates inside the slots can hold books for easy access. Using a hanging rope to hang the chair on a hook keeps the hollow armrests raised. The hollow sleeves are then pulled out from the cup slots to prevent tipping, and the retractable plate is pulled out to form a simple tabletop for placing books and other study supplies. Conversely, it can be retracted into the storage slot, presenting a flat shape, occupying little space, easy to carry, and convenient to unfold.
