Novel electric lifting chair

Abstract

The invention discloses a novel electric lifting chair and relates to the technical field of seats; the novel electric lifting chair comprises a base, a chair seat and a lifting device; the lifting device comprises a motor which is relatively fixedly connected with the base, a vertically arranged lead screw in transmission connection with an output shaft of the motor, a nut in threaded connectionwith the lead screw, a vertically arranged ejector rod fixedly connected with the nut, a sleeve arranged in the circumferential direction of the screw rod and a spring; the lead screw is rotatably connected with the base; the ejector rod can move in the axial direction of the sleeve, the two ends of the spring respectively apply pressure to the base and the bottom surface of the chair seat, and alinear guide rail is arranged in the sleeve, so that the nut moves up and down along the linear guide rail; and the ejector rod is fixedly connected with the bottom surface of the chair seat. Therefore, the problems that in the prior art, the operation of adjusting the height of the lifting chair is inconvenient and potential safety hazards exist are solved.

Description

technical field [0001] The invention relates to the technical field of seats, and more specifically, relates to a novel electric lift chair. Background technique [0002] As a common item in work and life, chairs have derived many chairs with convenient functions under the background of people's pursuit of high-quality life, especially lift chairs, which are widely used because of their height-adjustable advantages. [0003] But most of the lift chairs in the prior art are pneumatic lift chairs, the lift chair is provided with a cylinder, the cylinder is filled with nitrogen, and the piston rod in the cylinder moves up and down to control the lift of the seat seat. On the lift chair, put pressure on the piston rod, press the lift valve, the piston rod will descend smoothly, and release the lift valve after falling to the required height; when pressing the lift valve, if no pressure is applied to the seat, the piston rod will not be applied Pressure, the piston rod will boun...
