  • Patent number: 10966520
    Abstract: A cabinet locking device includes a cabinet body, a plurality of movable storage devices, a plurality of locking devices, and a driving device. The driving device is interlocked with the locking devices via a plurality of drawstrings. Each locking device includes a sliding member, an interference member disposed on the sliding member, and a restriction mechanism for guiding the sliding member. The driving device can drive the sliding member to move to an engaging portion or a released position. When the sliding member is moved to the engaged position, the interference member interferes with an engaging portion of the corresponding movable storage device such that the movable storage device cannot be opened. When the sliding member is moved to the released position, the interference member does not interfere with the engaging portion such that the movable storage device can be opened.
