Description

Technical Field

[0001] The utility model relates to the technical field of surveying and mapping devices, in particular to a surveying and mapping device which is convenient for adjusting the surveying and mapping height. Background Art

[0002] With the development of science and technology and the progress of the times, the surveying and mapping industry has also developed rapidly, which has promoted the birth of surveying instruments to a certain extent. At the same time, the application of surveying instruments is also very extensive, mostly used for measurement in the construction industry, measurement in the design industry, etc., playing an indispensable role.

[0003] Existing surveying and mapping instruments are often troublesome to adjust the height. The three legs are often prone to tipping over when separated, and it is not convenient to store and move the three legs connected.

[0004] For example, Chinese patent CN214951340U discloses a surveying and mapping device that is easy to adjust the surveying and mapping height. The height of the support column is conveniently adjusted by a fixing nut, and the auxiliary telescopic rod slides in the telescopic rod sleeve, which drives the stage to rise and fall as a whole. The operation is simple and the lifting and lowering are smooth. The bottom adjustment rod can slide in the bottom frame to facilitate the adjustment of the overall fixed position of the surveying and mapping instrument, making the overall placement more stable and reducing tipping. When transferring, the adjustment rod can be slid to the innermost side, and the three legs remain parallel for easy fixing and movement.

[0005] However, when the observation height needs to be temporarily changed during the observation process, the leveled stage will deviate and need to be re-leveled, thus affecting the surveying and mapping efficiency.

[0006] For this reason, we urgently need to provide a surveying and mapping device that is convenient for adjusting the surveying and mapping height. Utility Model Content
