Description

Technical Field

[0001] The utility model relates to the field of levels, in particular to a portable level calibration device. Background Art

[0002] The level is an instrument that establishes a horizontal line of sight to measure the height difference between two points on the ground. Its principle is to measure the height difference between ground points according to the principle of leveling. Levels are divided into micro-tilt levels, automatic leveling levels, laser levels and digital levels (also known as electronic levels) according to their structure. They are divided into precision levels and ordinary levels according to their accuracy. Levels appeared after the invention of telescopes and levels in the 17th and 18th centuries. In the early 20th century, micro-tilt levels were produced based on the production of internal focusing telescopes and levelers. Automatic leveling levels appeared in the early 1950s; laser levels were developed in the 1960s; and electronic levels or digital levels appeared in the 1990s. Levels are generally composed of a level body and a tripod bracket. During use, the staff needs to carry the level body and the tripod bracket to the site of use for assembly. After use, the staff needs to disassemble them and carry them, which is inconvenient to use. For this reason, a portable horizontal calibration device is proposed. Utility Model Content
