Revolving chair structure with stepless tipping regulation

Abstract

The invention discloses a revolving chair structure with stepless tipping regulation, which comprises a chair plate and a backrest, wherein a base plate is fixedly arranged at the bottom of the chair plate, the backrest is movably hinged with the base plate through a tail plate in a backward tipping manner, the front end and the rear end on the base plate, along the length extending direction, are respectively and fixedly spanned with at least one tipping regulation elastic plate, the tail plate is connected with the rear end of the tipping regulation elastic plate by a transverse rod, a worm is fixedly arranged at the front end of the base plate and is sheathed with a worm wheel box capable of sliding along the worm front and back, a sliding fulcrum seat that leans against the bottom end of the tipping regulation elastic plate is arranged at the bottom of the worm wheel box in an extending manner and can slide along the length direction of the tipping regulation elastic plate, and one side of the worm wheel box is further connected with a regulating handle that regulates the worm wheel box to slide front and back along the worm. The revolving chair structure is simple in structure, and large in regulatable angle, and the regulating handle is connected with the worm wheel box and the worm in a matching manner, so that the regulation of the rotation of the regulating handle is proper, the comfortableness brought by a revolving chair during use is effectively improved, and the regulation of the revolving chair is more humanized.

Description

technical field [0001] The invention relates to a swivel chair structure, in particular to a swivel chair structure with simple structure and good use effect with stepless tilt adjustment. Background technique [0002] At present, the existing swivel chair can adjust its backrest tilting angle to meet people's different sitting postures and lying needs.
