Abstract:
A leg-beautifying linkage mechanism that economizes on packaging space size, a kneading massage machine core and a massage chair. The lower end of a front support frame (5) is vertically fixed at the front end of a base frame (2), and the front end of a backrest iron frame (1) is hinged to the upper end of the front supporting frame (5); a leg-beautifying assembly (3) is hinged to the front end of the backrest iron frame (1); a cylinder body end of an electric push rod (4) is hinged onto the base frame (2); and a telescopic rod end of the electric push rod (4) is hinged onto the backrest iron frame (1); one end of a push-up connecting rod assembly is arranged on the backrest iron frame (1), and the middle of the push-up connecting rod assembly is arranged on the front supporting frame (5); and the other end of the push-up connecting rod assembly is connected to the lower side of the leg-beautifying assembly (3) in a rolling mode. The push-up connecting rod assembly is utilized, so that the linkage of a backrest frame rising and reclining, a leg-beautifying frame and a cushion frame may be achieved. In addition, when reclined, the height of the chair may be remarkably reduced, the space size of the whole machine is remarkably reduced, and great savings are made in terms of packaging costs. The leg beautifying frame may be put lowered and reset according to the weight thereof when the electric push rod (4) extends and retracts, and the leg beautifying frame cannot be clamped when an object or a pet is present underneath.
