Description
Technical Field
[0001] This utility model relates to the field of load-bearing drawer technology, specifically a three-section self-closing drawer with four times the load-bearing capacity, extending from a crane tower or bridge. Background Technology
[0002] Almost all medical pendant bridges are equipped with drawers as standard. Drawers are crucial in medical pendant bridges. First, they provide convenient storage. In medical settings, medical staff can store frequently used small medical tools, medications, and consumables in drawers for quick access during patient care, saving time—especially critical in emergency situations where every second counts. Second, they help maintain a tidy work area. Drawers can organize loose items, preventing them from scattering on the work surface and causing clutter, allowing medical staff to work more efficiently. Furthermore, given the extremely high hygiene requirements of the medical environment, drawers serve as a relatively independent storage space, protecting internal items from external contamination and facilitating unified cleaning and disinfection of items within the drawers.
[0003] Traditional drawer structures and materials are relatively conventional, making it difficult to withstand the storage needs of heavy items. The outer shell and inner liner of the drawer are prone to deformation and cracking, and may even damage the drawer slides, shortening the lifespan of the drawer. Most drawers lack effective cushioning devices, and when the drawer is closed, it is prone to strong collisions with the cabinet, which not only generates a lot of noise but also damages the cabinet and the drawer itself. After long-term use, the connection between the cabinet and the drawer is prone to loosening, affecting the overall structural stability. In addition, the internal space layout of existing drawers is fixed, and the position of the dividers is difficult to adjust, which cannot meet the user's needs for classifying and storing items of different sizes and types. To address these issues, this utility model provides a three-section self-closing, four-fold load-bearing drawer with a suspended bridge extension. Utility Model Content
