Description
Technical field
The present invention relates to technical field of furniture more particularly to a kind of office furniture with seat lifting function.
Background technique
Chair lift is a kind of novel chair, and traditional chair lift is mainly by seat board, backrest, bracket, bracket rocker arm, lifting
Positioning device and chair leg are constituted, and correspond to hingedly by bracket rocker arm between bracket and chair leg, bracket rocker arm is to be hinged on chair leg
Upper articulated shaft rotates upwardly and downwardly for the center of circle, drives bracket to be gone up and down when shaking bracket rocker arm, realizes the lifting of seat board；And it is daily
In life or the course of work, since lifting seat structure is complex larger so as to cause its quality, living environment is being swept
Or during working environment, moved seat is more difficult.
Particularly with pushing in the higher situation of environmental requirement, seat transfer is easy to cause secondary dirt to the environment after cleaning
Dye, thus best mode be by seat and surface separation, and tradition for the seat of lighter weight, by manually by it
It places on desktop, is moved down again after cleaning；And for the seat of heavier mass, it is moved down by manually bringing up to
While difficulty is larger, when moving down since gravity is easy to cause to damage to seat and ground.
Summary of the invention
The purpose of the present invention is in view of the deficiencies of the prior art, provide a kind of office man with seat lifting function
Tool after being set by control assembly to limit assembly position, during office chair is pushed to below desk, is synchronized and is propped up
