Description

Technical Field

[0001] This utility model relates to the field of cargo storage technology, specifically a multi-layer cargo storage rack with adjustable storage space. Background Technology

[0002] Goods storage racks, also known as warehouse racks, are a type of storage equipment based on the six basic functions of logistics: packaging, transportation, loading and unloading, sorting, and information management.

[0003] Currently, existing goods storage racks generally include placement panels, uprights, and reinforcing rods. Multiple placement panels are evenly arranged from top to bottom and are connected and fixed together by uprights. Multiple uprights are also arranged and are located at each corner of the placement panel. After the uprights are fixed to the placement panels with screws, the side uprights are reinforced by reinforcing rods, which are fixed to the uprights with screws.

[0004] The conventional goods storage racks mentioned above have some minor problems in actual operation. For example, the shelves are usually fixed, and when storing larger goods, the shelves must be replaced, which is quite limiting. When storing goods, the goods must be carried by hand and then placed into the storage rack and placed on the load-bearing plate. If you are not careful, the goods or the material rack may be bumped. Therefore, we propose a multi-layer goods storage rack with adjustable storage space. Utility Model Content
