Description

Technical Field

[0001] This utility model relates to the field of storage cabinets, and in particular to a folding storage drawer. Background Technology

[0002] CN222091122U discloses a folding storage cabinet. "When using the folding storage cabinet, first pull out the folding drawer, open and flip the front panel and back panel. Right-angle hinges limit the flipping angle of the front and back panels, keeping them in a vertical position. Then, flip the first and second side panels of the drawer, so that the sides of the first and second side panels engage with the locking blocks and slots on the front and back panels respectively to unfold the drawer." "When it is necessary to unfold the folding cabinet, flip the door-shaped frames at both ends. Right-angle slots are provided at the four corners of the top of the first and second bases." The patent describes a process where the door frame's rotation angle is limited to a certain degree. Then, the first and second side panels of the cabinet are rotated, and the card plate rotates along with the side panel it's on. The first and second side panels are engaged with the door frame, achieving initial fixation of the side panels. The card plate is then rotated upwards, engaging with the inner side of the top beam of the door frame, thus achieving secondary fixation of the side panels and ensuring stability after the first or second side panel is unfolded. At this point, the folding cabinet is fully unfolded. In this patent, the drawers and cabinet body are folded, significantly reducing the packaging volume of the drawer-type folding storage box.

[0003] The problem with existing technology is that the method of connecting the card plate to the door frame by "flipping it upwards to engage and fix it to the inside of the top crossbeam of the door frame, thus achieving secondary fixation of the side panel" is unreliable. If subjected to vibration, such as a child hitting the cabinet or moving the cabinet while it is in use, the card plate may fall downwards and detach from the door frame, in which case the card plate will interfere with the movement of the drawer. Alternatively, the connection precision between the card plate and the door frame may be low due to plastic shrinkage during the injection molding process, which can also cause the card plate to fall off easily.
