Document Type and Number:
WIPO Patent Application WO/2024/087966
Kind Code:
A1
Abstract:
Disclosed is a secure self-locking mechanism for a drawer. The secure self-locking mechanism for a drawer is arranged in a drawer cabinet provided with at least two drawers, and comprises a movable connecting piece and a secure driving block. A groove which matches the movable connecting piece is formed in a side panel of the drawer cabinet. Several self-locking nails and stop fixing pieces are arranged on the movable connecting piece. The secure driving block is fixed to the outer side of a drawer side panel and matchably slides with the self-locking nails to achieve the opening and closing of a drawer. Once one of the drawers is opened, a self-locking nail is linked with the movable connecting piece, so that the other self-locking nails on the movable connecting piece go down together to lock drawers that have not been pulled out. A secure toggle pin is arranged on the outer side of the movable connecting piece. The secure toggle pin extends out of a through hole provided in the side panel of the drawer cabinet, and the secure toggle pin is toggled to fully open or fully close the drawers. The present invention has a simple structure and low costs. Several drawers may be simultaneously fully locked or fully opened. During use, only one drawer may be opened while the other drawers are self-locked, so that the use thereof is secure and reliable. The drawers are fully locked during transportation, which is more secure and convenient.
