Description

A connection structure for a shelf Technical Field

[0001] This utility model belongs to the field of shelving assembly technology, specifically relating to a shelving connection structure. Background Technology

[0002] With social development and progress, in order to optimize the ecological environment and protect the health of frontline workers, some mainstream shelving produced or assembled by welding is gradually being phased out. Prefabricated shelving that is easy to transport and install is favored by consumers. However, with the increasing variety and styles of shelving, the market competition is fierce. Only shelving with higher sturdiness, simpler installation, and greater space utilization can stand out from the competition.

[0003] Current shelving mainly consists of uprights, connectors, beams, and shelves. Connectors are components that connect two adjacent uprights. In actual use, they are usually fixed to the two uprights using diagonal or horizontal connections. Beams connect two sets of uprights at intervals to the connectors, and shelves are placed on the beams to form the main body of the shelving. Existing connectors generally use pipes or plates to be fixed to the uprights with bolts or clips. As is well known, connectors need to be installed crosswise or horizontally at intervals along the height of the uprights. Some connectors obstruct the sides of the shelves, while others have open sections on both sides between the uprights. The former obstructs the placement of long items during storage, while the latter makes it easy for small items to fall through the open sections, neither of which meets consumer needs.

[0004] In view of the above, it is necessary to design a rack connection structure that is simple in structure, easy to assemble, and capable of providing a stable connection between the connectors and the uprights, while also allowing the connectors to work with the shelves to form a storage platform. To this end, the applicant has made a beneficial design, and the technical solution described below arose from this background. Utility Model Content
