Three-linkage lifting locating device for lifting and locating tea table

Abstract

The invention relates to a three-linkage lifting locating device for lifting and locating a tea table. The three-linkage lifting locating device comprises a fixed disc; the lower end of the fixed disc is provided with three pairs of connection columns; a Y-shaped fixing sheet is welded to the lower ends of the three pairs of connection columns; the middle of the Y-shaped fixing sheet is connected with a central shaft; the central shaft is connected with the fixed disc through a bearing; a central gear is arranged on the central shaft through a key; a firs ball bearing is arranged in the middle of the Y-shaped fixing sheet; a driving shaft is arranged on the first ball bearing; the top end of the driving shaft is connected with the fixed disc through a bearing; a driving gear is arranged in the middle of the driving shaft through a key; the Y-shaped fixing sheet is evenly provided with three locating mechanisms; the top ends of the three locating mechanisms are connected with a movably disc; the middle of the movable disc is connected with the central shaft in a clearance fit mode. The three-linkage lifting locating device for lifting and locating the tea table can achieve lifting and locating functions with high precision, and has the advantages of being simple in structure, easy and convenient to operate, good in balance performance and height locating performance in the movement process, high in working efficiency and the like.

Description

technical field [0001] The invention relates to the technical field of coffee tables, in particular to a three-link lifting and positioning device for lifting and positioning coffee tables. Background technique [0002] At present, the table tops of the general tea table are all fixed, and because the heights of different people are different, when people eat, write or study on it, it cannot reach the height that is comfortable for the human body, and this uncomfortable posture is still difficult to work for a long time. will affect people's health. Although in the prior art, there are some tea tables with lifting function, these tea tables basically realize the purpose of lifting through a single transmission mechanism or other single-point drive mechanisms that are prone to gaps, but this single-point drive mechanism must be in the lift. There will be a slight inclination in the process, and if people put teacups or other containers with water on it, it may overflow, whic...
