The invention relates to a rotary base and a rotary chair with a locking function. The rotary base comprises a fixing plate, a positioning mechanism, a rotating plate and a turntable bearing, wherein the positioning mechanism is fixedly arranged on the fixing plate; the turntable bearing is rotatably arranged on the fixing plate; the rotating plate is fixedly connected with the turntable bearing and is fixedly provided with a stop dog; the stop dog comprises an elastic piece, a linear bearing and a positioning pin; one end of the elastic piece is fixedly connected with the fixing plate; the other end of the elastic piece is connected with the positioning pin; the linear bearing is fixedly connected with the fixing plate and sleeves the positioning pin; the positioning mechanism is provided with a positioning groove; and the positioning pin is movably inserted in the positioning groove. By the linear bearing, the positioning pin cannot move in the radial direction when moving along the axial direction, and the popup direction of the positioning pin is accurate; and after the positioning pin is inserted in the positioning groove and is locked, the positioning pin which is fixed by the linear bearing cannot shift easily after being stressed, shaking amplitude is reduced greatly, and user perception is improved.
Description
technical field [0001] The invention relates to a seat, in particular to a rotating base and a rotating seat with a locking function. Background technique [0002] The swivel seat has the function of turning. The user can sit on the seat and rotate at various angles, which greatly facilitates the user's leisure and entertainment. When it is necessary to stop the rotation, the positioning pin on the stopper is inserted into the positioning slot, so that the seat The chair is stationary, but because the positioning pin is inserted into the positioning slot through the elastic force of the spring, the positioning pin has a certain degree of freedom in the radial direction, and the gap between the positioning pin and the positioning slot is large, resulting in the jamming between the positioning pin and the positioning slot. If the connection is unstable, even if the gap between the positioning pin and the positioning groove is millimeter level, this gap is enlarged by the dista...
