Description

Technical Field

[0001] The utility model relates to the technical field of level instruments, and more specifically, to a level instrument for construction engineering. Background Art

[0002] A level instrument for construction engineering is an optical level instrument, also known as an optical level or an optical spirit level. This kind of level instrument uses the optical principle to measure the horizontal line or height difference of the ground or a building. The optical level instrument is equipped with a telescope or a sight glass for observing the scale or horizontal line on the measuring rod. A horizontal disk is fixed at the bottom of the level instrument. This is a horizontal rotating disk. There is a liquid level on the horizontal disk for adjusting the level of the level instrument. Adjusting screws are provided on the level instrument for fine-tuning the horizontal disk to ensure the accuracy and precision of the level instrument. When using the optical level instrument for measurement, the operator will place the level instrument at the position to be measured and make it level by adjusting the horizontal disk. Then, use the telescope or sight glass to observe the scale on the measuring rod and record the measurement results to determine the horizontal line or height difference of the ground or a building. This kind of level instrument is usually used in construction, civil engineering and other fields that require precise horizontal measurement.

[0003] The level instrument needs to be supported by a tripod. The bottom end of the traditional tripod is in a sharp cone shape. The traditional level instrument for construction engineering is not convenient to adjust the height and has a poor scope of application.
