AI Technical Summary
Existing precision leveling rods are difficult to keep vertical in complex terrain conditions, leading to measurement errors and data failure. Traditional manual support methods are labor-intensive and their stability depends on operational experience.
A precision leveling rod comprising a stabilizing component and a vertical component was designed. Through a mechanical interlocking structure of movable groove, slot, spring and locking pin, combined with a fixed cone and threaded rod, the leveling rod can be quickly adjusted and firmly fixed to ensure verticality.
It effectively prevents the leveling rod from tilting or falling over, reduces measurement errors, improves measurement accuracy, and reduces operational difficulty and labor intensity.
