Working chair mechanism convenient to lift based on office furniture

Abstract

The invention relates to the technical field of office furniture, and discloses a working chair mechanism convenient to lift based on office furniture. The working chair mechanism comprises a chair seat, wherein a fixed block I is fixedly connected to the bottom of the chair seat; a groove is formed in the bottom of the fixed block I; a threaded rod is movably connected to the interior of the groove; a gear I is in threaded connection to the exterior of the threaded rod; and a gear II is in meshed connection to the outer side of the gear I. According to the working chair mechanism convenient to lift based on the office furniture, a pull rod is pulled, so that a magnet is separated from the threaded rod; and a rotating rod is rotated, so that the threaded rod moves up and down, and the chair seat further moves up and down, and subsequently, an effect of safely lifting an office chair is achieved. When the chair seat is driven to ascend by virtue of the threaded rod, a connecting rod IIIand a connecting rod IV are driven to move upwards by virtue of the threaded rod, so that front supporting legs and rear supporting legs move towards the outer sides of supporting rods; and therefore, an effect of preventing the office chair from standing unstably due to gravity center ascending after the office chair ascends is achieved.

Description

technical field [0001] The invention relates to the technical field of office furniture, in particular to a work chair mechanism based on office furniture that is easy to lift. Background technique [0002] Office furniture is an appliance equipped for the convenience of office or work in daily work and social activities. The existing office chairs basically do not have a lifting function, and the commonly used lift chairs mainly use the lever principle to control the cylinder, but this This kind of chair is easy to suddenly heat up inside the cylinder during the frequent lifting process, causing an explosion phenomenon, and how to make the office chair can be raised and lowered safely has become an important problem, so we propose a work chair mechanism based on office furniture that is easy to lift . Contents of the invention [0003] (1) Solved technical problems [0004] Aiming at the deficiencies of the prior art, the present invention provides an easy-to-lift work ...
