Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of engineering surveying, in particular to a portable structure of a level. Background Art
[0002] A level is a commonly used measuring tool for measuring small angles. In the machinery industry and instrument manufacturing, it is used to measure the inclination angle relative to the horizontal position, the flatness and straightness of the guide rails of machine tools, the horizontal and vertical positions of equipment installations, etc. There are many different types of levels, including bubble levels, basic levels, rotary levels, laser levels, etc. Among them, laser levels can be used to mark ground heights, horizontal lines, etc., and are often used in water conservancy and hydropower topographic surveys and engineering planning.
[0003] For the convenience of carrying, most existing laser levels have a portable structure, and most existing portable structures are storage boxes with handles. When not in use, the level is placed in the storage box and carried by hand (as shown in the attached manual). Figure 4 However, most of the existing laser levels need to be used with a supporting tripod bracket. The existing portable storage box can only store the laser level but cannot store the tripod bracket attached thereto. The tripod bracket needs to be carried by hand separately, which undoubtedly makes it inconvenient to carry. Utility Model Content
