Description

Technical Field

[0001] This utility model relates to the field of companion bed technology, and in particular to a turning structure for a companion bed for the elderly. Background Technology

[0002] The companion bed is a safe bed with multiple nursing functions designed according to the bedridden living habits and treatment needs of elderly patients. It allows family members to adjust the bed through the control lever, making it easier for them to take care of the patient. The turning structure of the companion bed is a turning structure that assists elderly patients in turning over.

[0003] Chinese Patent Publication No. CN219166927U discloses a nursing bed that assists in turning over, including a main structure of the nursing bed with second mounting grooves on both sides of the main structure. This invention fixes limiting plates to both ends of the bottom of the main structure, fixes blocks to the bottom of the limiting plates, fixes a telescopic assembly to the surface of the main structure, and fixes a moving plate to the bottom of the output end of the telescopic assembly. Limiting grooves are provided inside both ends of the moving plate, allowing the telescopic assembly to extend and retract, causing the moving plate to move longitudinally along the limiting plates through the limiting grooves. This, in turn, causes the casters at the bottom of the moving plate to move longitudinally, thereby moving the accompanying bed upwards. When the accompanying bed is stationary, the telescopic assembly moves the casters upwards through the moving plate, allowing the main structure of the nursing bed to be placed stably on the ground, making the accompanying bed more stable and convenient to use.

[0004] Traditional elderly care beds lack limiting and guiding mechanisms during the turning process, making it difficult to ensure the accuracy of their rotation trajectory. After long-term turning operations, the turning structure is prone to displacement, which will adversely affect its relative stability, and its installation position is also difficult to accurately locate.
