Description

Technical Field

[0001] This utility model relates to the field of lifting device technology, and in particular to a synchronous lifting mechanism. Background Technology

[0002] Traditional lifting mechanisms generally adopt single-point drive or split-type adjustment structures, which often face the following technical defects during platform lifting: (1) insufficient synchronization of multi-point lifting, resulting in platform tilting and deviation, affecting accuracy; (2) unreasonable distribution of rigid support structure, which easily causes structural deformation during platform lifting; (3) high complexity of transmission system, difficult maintenance and difficulty in achieving precise fine adjustment. Especially in the application of edge banding conveyor platform of edge banding machine, the above problems will lead to a significant decrease in equipment stability, which seriously limits the application of lifting mechanism in high-precision operation scenarios. Summary of the Invention

The transmission assembly is connected to the multiple up-and-down sliding assemblies respectively. The synchronous adjustment element 2 and the transmission assembly cooperate to control the multiple up-and-down sliding assemblies to move synchronously up and down. Specifically, this utility model has a novel structure and ingenious design. When the height of the external platform needs to be adjusted, the transmission component is driven by the synchronous adjustment component 2 to drive multiple sliding components to move up and down synchronously, thereby driving the external platform to move up and down.
