Technical Field

[0001] This utility model relates to the field of rotating cabinet technology, specifically an external power supply wiring structure for a rotating cabinet. Background Technology

[0002] Floor-standing rotating cabinets mainly include rotating bookshelves, rotating bookcases, and rotating figurine cabinets. They are primarily composed of a cabinet body and a base at the bottom of the cabinet. The cabinet body and base are rotatably connected, providing storage and display functions. When used for display, lighting fixtures, displays, and other electrical appliances are usually placed inside the cabinet. Because it is difficult to maintain rotation while connected to an external power source, rechargeable electrical appliances are often used to avoid the problem of external cables getting tangled and knotted due to the cabinet's rotation. For example, multiple unrelated light fixtures can be fixed to the bottom of the shelves one by one using double-sided tape or magnets. However, rechargeable electrical appliances require frequent charging, and frequent bonding or magnetization also poses a risk of the appliances falling off, resulting in a poor user experience and failing to adequately meet the increasingly diverse storage and display needs of rotating cabinet products.
