Description

Technical Field

[0001] The utility model relates to the technical field of measuring instruments, in particular to a measuring instrument which can be quickly erected. Background Art

[0002] Engineering surveying instruments are measuring instruments that are used for various types of orientation, distance, angle, height, mapping, and photogrammetry in the planning, design, construction, and management stages of engineering construction. When in use, the bracket needs to be connected to the main body of the measuring instrument before measuring. The existing connection method between the bracket and the measuring instrument is too complicated, which makes it difficult to change the angle and shoot during measurement.

[0003] According to a surveying instrument for engineering construction investigation that can be quickly erected (publication number: CN215177742U), in the above application, the pull rod of the surveying instrument slides outward on the sleeve plate, and the push plate is pulled by the pull rod. The push plate will press the telescopic rod and the spring to shrink together. The push plate will also drive the plug rod to open the top of the placement slot. After that, the staff will put the connecting block connected to the bottom of the measuring instrument body into the placement slot, and then the staff will loosen the pull ring, drive the telescopic rod to stretch through the spring, and insert the three plug rods into the inside of the installation hole at the same time, so as to achieve the effect of quick installation.

[0004] However, when the above-mentioned measuring instrument is used and needs to perform multi-angle measurements, it is necessary to change the position of the moving bracket, which is greatly restricted by the terrain. In some places with bad environments, it may be difficult to change the angle of the bracket, which is not conducive to the multi-angle use of the measuring instrument. In view of this, we propose a measuring instrument that can be quickly set up. Utility Model Content
