Abstract

The invention discloses an office chair for health care. The office chair for health care comprises a seat frame, seat legs, a seat back, a seat plate which is movably connected with the seat frame and free of relative autorotation, a direct-current gear motor arranged on the seat frame, a main driving shaft directly driven by the direct-current gear motor, a seat plate driving wheel which is connected with the main driving shaft through a belt and arranged on the seat frame through a driving wheel rotating shaft, an eccentric rotating shaft which is arranged on the seat plate driving wheel and used for driving the seat plate to conduct eccentric rotating and a circuit control system; the back face of the seat plate is provided with an installation shaft matched with the eccentric rotating shaft and connected with the seat plate driving wheel through the installation shaft; the diameter of the seat plate driving wheel is larger than that of the main driving shaft, and the distance between the arranging axis of the eccentric rotating shaft and the rotating axis of the seat plate driving wheel is larger than the radius of the main driving shaft. The office chair for health care further comprises a torsion braking device capable of enabling the seat plate to stop rotation through a friction mode and a conducting switch device used for making the circuit system powered off. The office chair for health care has the advantages of being leisure and safe.

Description
