Description
Technical Field
[0001] This utility model relates to the field of warehousing technology, specifically to a movable multi-layer mobile rack with an adjustable structure. Background Technology
[0002] Multi-layer mobile racks are warehousing equipment used for material storage and handling. They feature a multi-layer structure and are mobile, and are widely used in many fields such as manufacturing, logistics, and warehousing. Existing multi-layer mobile racks usually adopt a lightweight design to facilitate movement, which results in a relatively limited load-bearing capacity of each layer. When storing heavy or large items, the load-bearing capacity of the rack may be insufficient, leading to deformation or even damage to the rack and affecting the safety of the materials.
[0003] A search revealed a utility model patent with publication number CN222158562U, which specifically discloses a multi-layer material rack for logistics sorting, comprising: a support frame; a first material tray fixedly connected to the support frame; and a second material tray, one or more of which are located below the first material tray and movably connected to the support frame. The second material tray has a storage position within the support frame and a pick-and-place position outside the support frame. This multi-layer material rack, by moving the second material tray outside the support frame, provides sufficient space for picking and placing materials, thus reducing the difficulty of material handling and placement by eliminating spatial limitations between layers.
[0004] The aforementioned patent only uses a support frame and a tray to store materials, which cannot fully adjust the space of the rack, making it inconvenient to store more materials and make reasonable use of the space, thus avoiding space waste.
