<p>A fitness bed comprises four pushing apparatuses (10) and a central power apparatus (20). The four pushing apparatuses (10) are separately disposed at positions corresponding to four limbs, located below a bed plate (41) of the fitness bed, and are used for pushing the four limbs to move up and down. The central power apparatus (20) provides rotation power for the crankshaft (13) of each pushing apparatus (10). The central power apparatus (20) comprises a transmission case (21), a driving bevel gear (22) disposed in the transmission case (21), four driven bevel gears (23) separately engaged with the driving bevel gear (22), and a power generation apparatus for driving the driving bevel gear (22) to rotate. The driven bevel gears (23) are separately connected to the crankshaft (13) of each pushing apparatus (10). The foregoing fitness bed drives the crankshafts (13) of the pushing apparatuses (10) by using the central power apparatus (20), so that the pushing apparatuses (10) can drive the four limbs of a human body to move. Because the central power apparatus (20) and the pushing apparatuses (10) can be separately manufactured, the central power apparatus (20) and the pushing apparatuses (10) have a simpler structure, provides lower cost, are suitable for a family, a fitness room, a hospital and a workplaces, and are used for fitness by using the corresponding bed plate (41) together.</p> |
