AI Technical Summary
Existing laser rangefinders suffer from reduced measurement accuracy or failure under complex working conditions due to factors such as target transmittance, horizontal position, and environmental conditions, making them unsuitable for complex construction environments.
It employs support legs, elevated brackets, a level, a rotating dustproof frame, a laser transmitter, and an infrared receiving assembly, combined with leveling and extension positioning components, to ensure the laser transmitter is level and adapts to complex target shapes via flexible steel strips and reflectors, protecting the laser from dust and moisture and achieving stable ranging.
By using an independent, movable reflector to force the reflection of the laser signal, it adapts to complex target shapes, ensures ranging accuracy, protects the laser, reduces environmental interference, and achieves stable ranging.
