[0002] Nursing beds are widely used in general hospitals (for long-term bedridden and postoperative patients, meeting needs such as body positioning and wound care), ICUs (providing fall protection for critically ill patients and facilitating emergency treatment), and nursing homes (serving elderly patients with chronic diseases and disabilities, facilitating daily living). They not only provide nursing support for bedridden patients and those with mobility issues, allowing family members to manage their eating and drinking, but also assist in repositioning patients in rehabilitation centers, laying the foundation for rehabilitation training, such as standing training for spinal cord injury patients.

[0003] Nursing beds provide a stable and comfortable lying platform, supporting the body according to the patient's body shape and needs, avoiding problems such as muscle soreness and poor blood circulation. Through auxiliary care, they can help patients turn over to reduce pain, facilitate the movement of patients to avoid injury, and facilitate daily operations such as feeding and wiping the body for caregivers, thereby reducing the labor intensity of caregivers.

[0004] However, most existing nursing bed frames are connected by bolts to ensure stability. However, in actual use, due to the large size and weight of the bed frame, it is inconvenient to transport, store and partially replace it.
