AI Technical Summary

Technical Problem

The existing rulers require workers to climb up when measuring the horizontal length of objects at high places, resulting in slow measurement speed, inconvenience and safety risks. Traditional rulers are prone to errors during use.

Method used

A level ruler is designed to facilitate elevation measurement and staking. Through the rotational connection between the linkage plate and the base ruler, the telescopic ruler can lift and measure the horizontal length of objects at a height, and improve stability and accuracy through structures such as limiting plates, baffles and friction protrusions to reduce errors.

Benefits of technology

Fast, safe and accurate measurement of horizontal lengths of objects at high altitudes is achieved, reducing the working intensity and safety risks of operators, improving measurement efficiency and accuracy, and reducing production costs.
