AI Technical Summary
In existing electric heating tables, the question of whether the middle layer needs to rise and fall along with the tabletop leads to the need for an additional lifting system design, increasing the structure and cost. Furthermore, the lack of multi-point guidance and limit during the lifting process results in poor durability.
The system employs a linkage mechanism, which uses a lifting slider and a middle-layer lifting column to achieve synchronous lifting of the middle layer and the desktop. The drive mechanism drives the push rod to move the lifting slider, which in turn lifts the middle layer. Combined with guide rails and guide sliders, this ensures a stable and precise lifting effect.
It achieves coordinated lifting of the middle layer and the desktop, which simplifies the structure, reduces costs, and improves the stability and durability of the lifting mechanism.
