Description

Technical Field

[0001] The utility model relates to the technical field of surveying and mapping instruments, in particular to a surveying and mapping instrument for engineering surveying and mapping. Background Art

[0002] Engineering surveying and mapping instruments are measuring instruments that are used for various types of orientation, distance, angle, height, mapping and photogrammetry required for surveying work during the planning, design, construction and management stages of engineering construction.

[0003] Although the surveying instruments currently used can meet the use requirements, they still have defects in the actual operation process. For example, a surveying instrument for engineering surveying provided by the authorization announcement number CN216770616U limits the support column by a bracket, installs the surveying instrument body on the mounting plate, pulls the limit rod, and the reset spring is deformed by force. The limit rod is inserted into the limit hole to limit the mounting plate. When the angle of the surveying instrument body needs to be adjusted, the finger is inserted into the groove, and the groove is forced to drive the limit rod, and the limit rod is pulled out of the limit hole to adjust the mounting plate. The bottom of the mounting plate rotates in the mounting seat to adjust the angle of the mounting plate. After the angle adjustment is completed, the limit rod is pulled again, and the limit rod is inserted into the limit hole. The limit hole limits the mounting plate through the limit rod to prevent the angle adjustment of the mounting plate. Through the limit assembly, it is convenient to adjust the angle and limit the main body of the surveying instrument group, which is convenient for surveying and mapping the project in all directions;

[0004] However, the surveying instrument does not have a height adjustment function during use, and is not convenient for people of different heights to use. Some people need to bend over to observe when using it, and there are certain defects in its use. For this reason, we propose a surveying instrument for engineering surveying to solve the above problems. Utility Model Content
