Description

Connecting rod lifting tabletop mechanism Technical Field The utility model relates to the field of plane lifting, in particular to a connecting rod lifting tabletop mechanism. Background The desktop is lifted, and the requirement of a user on the use height of the desktop is realized through the lifting of the desktop. The existing lifting table is poor in stability, and objects on the table top are likely to be displaced in the lifting process. Under the scene that the requirements on plane stability such as billiard ball motion, precision instrument maintenance are high, easily cause the influence to work, the practicality is poor. Patent document with publication number CN215501731U discloses an automatic lifting table, drives the second connecting rod to swing up and down through the gear, realizes the lift of desktop, and there are some problems in this scheme in the actual time, and the gear drive second connecting rod will lead to the gear that both meshed bear very big moment of torsion, and long-term use, the desktop pressure-bearing is great just leads to the gear to damage easily. Disclosure of utility model In order to solve the technical problems, the utility model provides the connecting rod lifting tabletop mechanism, wherein the connecting rod drives the swing rod to swing so as to realize lifting of the tabletop, so that the tabletop is more stable and the bearing is larger. The utility model solves the technical problems by adopting the technical proposal that the connecting rod lifting tabletop mechanism comprises a base, a lifting column, a tabletop and a lifting assembly; The base is fixed with the lower end of the lifting column, the lifting column is connected with the desktop supporting table through a plurality of lifting components, and the lifting components are distributed on the periphery of the lifting column; the lifting assembly comprises a swing rod and a connecting rod; The lower end of the swing rod is hinged with the main body of the lifting column, the upper end of the swing rod is hinged with the sliding block, the lower surface of the tabletop is provided with a sliding rail extending from inside to outside, and the sliding block is in sliding fit with the sliding rail; One end of the connecting rod is hinged to the lifting end head of the lifting column, and the other end of the connecting rod is hinged between two ends of the swing rod. When the lifting column is lifted upwards, one end of the connecting rod moves upwards along with the lifting end, and then the middle part of the swinging rod is pulled, so that the upper end of the swinging rod swings upwards, the swinging rod is adapted to the relative position with the tabletop through sliding of the sliding block on the sliding rail, and the upper end of the swinging rod pushes the tabletop upwards to lift.
