Description

Technical Field

[0001] The utility model relates to the technical field of observation and adjustment equipment for building detection, in particular to an observation and adjustment equipment for building detection. Background Technique

[0002] During the building construction process, it is usually necessary to use a level to observe during building detection. Specifically, a level is an instrument used to establish a horizontal line of sight to measure the height difference between two points on the ground. Its basic principle is to use the equilibrium state of the liquid surface under the action of gravity to determine the horizontal position of the ground, so as to achieve the purpose of measuring the height difference. The level determines the height difference between ground points by observing the liquid surface in the level tube. This is crucial in fields such as civil engineering, geological exploration, and road surveying. It directly relates to the levelness and perpendicularity of the project, and thus the project quality. Therefore, it is necessary to observe during building construction.

[0003] Specifically, when building observation is required, first install the instrument on a telescopic tripod and place it between two observation points, and check whether the tripod is firm. Then rotate the telescope to make the image of the leveling staff clear on the crosshair. However, for the adjustment of the level, in the prior art, the tripod is fixed on the ground, and then the instrument is installed on the tripod, and the eyepiece and objective lens on the instrument are adjusted to observe the building. However, when adjusting in this way, the angles and positions of the instrument measurement are adjusted relatively too limited, and it is too troublesome to extend and retract the tripod again for the measured height. Based on the above problems, we propose an observation and adjustment equipment for building detection. Content of the Utility Model
