Description

Technical Field

[0001] The utility model relates to the technical field of hospital beds, in particular to a medical nursing bed with variable speed swing. Background Art

[0002] At present, most medical nursing beds have a rocking function, and patients can choose whether to use the rocking function to relieve pain or help sleep according to their needs. However, the speed of the rocking function of existing beds is mostly specific, and the gear speed cannot be adjusted.

[0003] For example, the utility model with patent number CN200520074955.8 discloses a rocking device for the core frame of a medical bed, including a bed frame, a core frame and a core rocking mechanism. The core frame is supported on the bed frame by rolling bodies. After the core frame is placed on the bed frame, there is a rocking gap between the two in the length direction. The core rocking mechanism is a crank-connecting rod mechanism or a connecting rod eccentric wheel mechanism. When the transmission wheel in the core rocking mechanism is rotated, the core frame will rock left and right under the action of the connecting rod. Since rolling bodies are arranged between the core frame and the bed frame, and a core rocking mechanism is arranged between the bed frame and the core frame, as long as the transmission wheel is rotated, the core frame will rock regularly, and its swing amplitude is determined by the eccentricity of the eccentric wheel or the eccentricity of the crank. This core frame rocking device can be manual or electric, and can make the core frame of the bed rock regularly to meet the needs of patients.

[0004] Although the core frame of the hospital bed in this patent can swing, the speed cannot be changed and it cannot be suitable for people with different needs. In addition, the core frame of the bed is not provided with a limiting mechanism. Over time, it will shift or tilt, affecting the use of the bed in a lying position. Utility Model Content
