The invention discloses a rotary seat based on adjustability, which comprises a seat unit, a rotating unit and a lifting unit, wherein the seat unit comprises a cushion, a backrest, an adjusting pieceand a supporting piece, the rotating unit comprises a base, a fixing piece, a disc, a connecting shaft, a first gear and a reversing piece, and the lifting unit comprises a first hinge support, a first sliding support, a second hinge support, a second sliding support, a first connecting rod, a second connecting rod, a connecting column, a third hinge support and a telescopic piece. According to the device, the reversing pieces of the four gears are adopted, and the steering direction of the seat can be changed at will on the premise that the circuit of the second motor is not changed; the backrest can be rotated to be horizontal, and through a series of matching of structures such as a fixed plate, a first sliding plate and a second sliding plate in the supporting piece, the triangular support can regularly extend out to support the backrest on the premise of not changing the circuit of the first motor; andthe seat can be adjusted to ascend and descend through the lifting unit.
本发明公开了一种基于可调节的旋转座椅,包括座椅单元、旋转单元和升降单元,座椅单元包括坐垫、靠背、调节件和支撑件,旋转单元包括底座、固定件、圆盘、连接轴、第一齿轮和换向件,升降单元包括第一铰接支座、第一滑动支座、第二铰接支座、第二滑动支座、第一连接杆、第二连接杆、连接柱、第三铰接支座和伸缩件。本发明所述装置通过采用4个齿轮的换向件,可以在不改变第二电机线路的前提下,随意改变座椅的转向方向;靠背可旋转至水平,通过支撑件中固定板、第一滑动板和第二滑动板等结构的一系列配合,可以在不改变第一电机线路的前提下,使三角支撑进行有规律的伸出以支撑靠背;通过升降单元可以使座椅进行升降调节。
