Description

Technical Field

[0001] The utility model relates to the technical field of geographical surveying and mapping, in particular to a lifting type geographical surveying and mapping instrument. Background Art

[0002] Geography is a comprehensive basic subject. Geography is a subject that studies various natural and human phenomena in the geographical environment on the surface of the earth, as well as the relationship between them. It combines optics, machinery and electricity to process the workpiece in a computer and magnify it 18 to 230 times, and display it on the screen. You can directly take pictures for archiving or do surface observation, measurement, and drawing. The measurement data can be used for SPC statistics and made into EXCEL reports. The drawing files can be converted into AUTOCAD applications. AUTOCAD graphics can also be transferred into computer software for comparison with the workpiece to make data, which can be stored and printed on the computer and can be transmitted through the network. The existing patent, patent announcement number CN219473305U, discloses a lifting type geographic surveying and mapping instrument. The lifting type geographic surveying and mapping instrument comprises a storage platform and grooves equidistantly provided inside the platform, the inner wall of the groove is hinged with a support assembly, a threaded through hole is provided inside the storage platform, a threaded rod is passed through the internal thread of the threaded through hole, a surveying instrument body is clamped on the top of the threaded rod, a rotating disk is threadedly connected to the outer wall of the threaded rod, a driving handle is welded to the top of the rotating disk, a support platform is connected to the bottom bearing of the rotating disk, and the end of the support platform far from the rotating disk is fixedly connected to the storage platform. The utility model effectively avoids the problem that the existing device is prone to support angle deviation and re-leveling when lifting after leveling, which is conducive to saving labor costs and improving the efficiency of adjusting and lifting the surveying instrument.

[0003] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: during use, the existing device is prevented from lifting and lowering after leveling, which may cause the support angle to deviate and need to be re-leveled. However, in actual use, when the position of the surveying instrument needs to be adjusted horizontally, the surveying instrument needs to be moved as a whole, and the surveying instrument body needs to be replaced when different measurement results are required. If it is inconvenient to replace it, the subsequent use of the surveying instrument will affect its convenience. Therefore, we propose a lifting type geographic surveying instrument to solve the above-mentioned problems. Utility Model Content
