Abstract

The invention discloses a linkage-type lifting chair. The linkage-type lifting chair comprises footrest mechanisms, a T-shaped seat plate, a seat plate lifting mechanism, a backrest mechanism, a seat frame and a telescopic pushing rod, wherein the footrest mechanisms are bilaterally symmetric and are connected with the left end of a transverse section of the T-shaped seat plate; the lower end part of a vertical section of the T-shaped seat plate is connected with the seat plate lifting mechanism; the right end of the transverse section of the T-shaped seat plate is connected with the backrest mechanism; the backrest mechanism is connected with the footrest mechanisms through straight linkage rods; the bottom of the telescopic pushing rod is hinged to a transverse shaft on the seat frame; the front end of the telescopic pushing rod is hinged to a middle transverse beam; the left and right ends of the middle transverse beam are fixedly connected with the middle of a driving component respectively; a spring is connected between the middle of a first connecting rod and the T-shaped seat plate; the middle of a first seat plate support is hinged to a first lifting connecting rod; the upper part of the first seat plate support is hinged to the right end of the driving component; the lifting mechanism is connected with a second seat plate support. The linkage-type lifting chair is simple in structure, convenient to operate and lower in cost, and has rich functions.

Description

technical field [0001] The invention relates to a chair structure, in particular to a lifting chair. Background technique [0002] With the development of social economy, people's living standards are improving day by day, and the phenomenon of aging of the elderly is increasing day by day.
