AI Technical Summary
The existing wedge lifting mechanism reduces the length of the mating surface when the height is increased, resulting in an unstable center of gravity. Furthermore, the wedge block may protrude from the assembly surface, becoming an obstacle and limiting its application range.
The wedge block lifting mechanism with double mating surfaces uses staggered wedge-shaped inclined surfaces arranged side by side on the lower surface of the upper wedge block to slide and engage with the lower wedge block. The two lower wedge blocks are driven synchronously by the drive component to lift the upper wedge block, ensuring that the point of force application is always in the center and avoiding instability and protrusion.
It achieves stable force distribution on the wedge-shaped lower block throughout its entire stroke, expands its application range, avoids instability of the center of gravity and protrusion from the assembly surface, and improves the stability and flexibility of the mechanism.
