In one embodiment, the rack 200 includes a main frame 210, a housing 220, and a plurality of frames 230, wherein the housing 220 is wrapped around the main frame 210, the main frame 210 is formed with at least two storage areas 212, the frames 230 are distributed in multiple layers and multiple rows in the storage areas 212, and each frame 230 forms a storage cavity 231. In this embodiment, each storage chamber 231 is independently formed. Of course, in a specific application, the formation manner of the storage cavity 231 is not limited thereto, and for example, as an alternative embodiment, a plurality of storage cavities 231 may be integrally provided.

As an embodiment, the second guide rail 114 is disposed below the first guide rail 111 at intervals along the height direction (i.e., the vertical direction) of the shelf 200, and the distance from the first guide rail 111 to the bottom of the shelf 200 and the distance from the second guide rail 114 to the bottom of the shelf 200 are smaller than the distance from the storage cavity 231 to the bottom of the shelf 200. The first rail 111 and the second rail 114 are both disposed near the bottom of the pallet 200, i.e., the first rail 111 and the second rail 114 are both located below the centerline of the pallet 200 in the height direction. The connection position of the first sliding component 112 and the lifting mechanism 120 and the connection position of the first sliding component 112 and the lifting mechanism 120 are both close to the bottom of the lifting mechanism 120.

As an embodiment, racks 1133 are disposed below the first rail 111 at intervals along the height direction of the shelf 200, and the distance from the racks 1133 to the bottom of the shelf 200 is smaller than the distance from the storage chamber 231 to the bottom of the shelf 200. Racks 1133 are disposed near the bottom of pallet 200, i.e., racks 1133 are below the centerline of pallet 200 in the height direction.

The foregoing description is only of the preferred embodiments of the present utility model and is not intended to limit the scope of the utility model, and all equivalent structural changes made by the description of the present utility model and the accompanying drawings or direct/indirect application in other related technical fields are included in the scope of the utility model.
