The present application relates to the field of storage machine, and provides a shelf and a storage cabinet. The shelf includes a lifting storage-board assembly, a driving assembly and a transmission assembly. The transmission assembly includes a plate body and a flexible cable, where the plate body is connected to a transmission shaft. The plate body includes an accommodation cavity and an arc groove, where a first end-opening of the arc groove is communicated with the accommodation cavity, and a second end-opening of the arc groove is communicated with an outside of the plate body; and a first end of the flexible cable passes through the arc groove to be fixed in the accommodation cavity, and a second end of the flexible cable is configured to wrap around a mounting portion of the plate body and then connect to the corresponding lifting storage-board assembly.

An expandable stand-alone shelving assembly includes a post assembly and an expandable shelf. The post assembly includes an elongated post and a sleeve coupled to the elongated post. The expandable shelf includes an aperture, a first half, a second half, and an internal mechanism. The aperture accepts the sleeve of the post assembly. The first half of the expandable shelf includes a surface, a top end, and a bottom end. The second half of the expandable shelf includes an angled portion extending downwards from a surface of the second half. The internal mechanism includes a reinforcement bar connecting the top end and the bottom end of the first half, and a stop. The second half is slidably received within the first half. The stop of the internal mechanism engages with the angled portion of the second half to prevent the second half and first half from sliding apart.

A safety cabinet can include an enclosure defining an interior compartment accessible through an opening. The safety cabinet includes an interior lighting system. The interior lighting system can include at least one of an illuminating light to enable viewing to cabinet contents and an ultraviolet light configured to disinfect the interior compartment of the safety cabinet. To provide electrical power to the interior lighting system, the safety cabinet includes an electrical connection disposed through the enclosure. The electrical connection can include at least one of a bulkhead connector and an intumescent socket.

A vertical displacement stopping system includes a sliding guide mechanism, a locking mechanism and a bearing mechanism. The locking mechanism, having positioning holes, includes positioning pins, telescopic mechanisms, and a handle located at a front portion of the bearing mechanism, wherein the handle is connected with the positioning pins through transmission parts, respectively. Each of the telescopic mechanisms includes a housing having a chamber, a movable block located within the chamber, and a reset spring located between a top portion of the movable block and the housing, wherein each of the transmission parts is connected with each of the positioning pins through the movable block.

Proposed is a refrigerator having a shelf assembly in which the shelf assembly includes a shelf installed inside a cabinet defining a storage space of the refrigerator and allowing food and a container to be seated thereon, a shelf fixing bracket fixed to each of opposite sides of the shelf and supporting the shelf, a lift rail module installed to be vertically long inside the cabinet such that the shelf fixing bracket is vertically movable, and a lift module installed slidably on one side of the shelf and configured to selectively release the shelf fixing bracket held by the lift rail module according to a user's manipulation.

An adjustable refrigeration rack system may include a pair of parallel shafts arranged on a rear interior cabinet side of a refrigerator, a plurality of pairs of attachment mechanisms, each attachment mechanisms having one attachment mechanism arranged on one rail, and another arranged at equal height on the other rail, the attachment mechanisms configured to hold a shelf and selectively engage the respective shafts, and a drive mechanism configured to drive the shafts vertically, wherein movement of the shafts causes movement of the shelf arranged on the attachment mechanisms selectively engaged with the shafts, but not movement of a shelf arranged on the attachment mechanisms unattached to the shafts.
