Connecting assembly of storage rack and storage rack

A connecting assembly of a storage rack comprising:

• a connecting sleeve body, the connecting sleeve body being used for sleeving a supporting rod;
• a position limiting device, the position limiting device being arranged on the connecting sleeve body, and the position limiting device being used for preventing a storage tray from rotating around the supporting rod in a circumferential direction;
• and
• a locking device, the locking device being used for locking the connecting sleeve body onto the supporting rod;
• wherein the locking device comprises a first connecting member and a second connecting member, the first connecting member is provided on the connecting sleeve body, and the first connecting member is connected to the second connecting member to lock the connecting sleeve body onto the supporting rod;
• wherein the position limiting device comprises an engaging member fixedly connected to an upper end surface of the connecting sleeve body and longitudinally extending therefrom, and the engaging member is used for engaging with an engaging slot of the storage tray to limit circumferential rotation of the storage tray around the supporting rod;
• wherein the engaging member is an approximately semicircular arc-shaped sheet coaxial with a longitudinal axis of the connecting sleeve body, a thickness of the engaging member is less than a thickness of the connecting sleeve body, and when the engaging member engages with the engaging slot, a bottom surface of the storage tray abuts against the upper end surface of the connecting sleeve body.
