Description

Technical Field

[0001] The utility model relates to the technical field of on-site measuring devices, in particular to an on-site measuring device. Background Art

[0002] Due to the installation requirements of custom furniture, it is necessary to accurately measure the size error of the wood product installation site and make a practical plan suitable for the installation site. The installation accuracy of wood products needs to be horizontal and vertical, but at present, due to the uneven construction technology (the national standard requires a 3mm error within 3 meters), the horizontal error of the ground and the horizontal error of the ceiling are large, so on-site measurement is required; currently, on-site measurement mainly relies on the measurement experience of the surveyor, and the main tools are spirit level and tape measure. When measuring, use the spirit level to project the horizontal line, use the tape measure to measure the height between the ceiling and the horizontal line at multiple points, and compare multiple points to obtain the error and height.

[0003] Since the tape measure is soft and not vertical, the measured size error is large and inaccurate. It is valid for data measured with reference points and auxiliary points. However, for data measured without reference points and auxiliary points, the accurate size cannot be obtained due to the influence of human factors, the accurate error cannot be calculated, and the data cannot be used.
