Description

Technical Field

[0001] The utility model relates to the technical field of measuring equipment, in particular to a portable measuring device used for land change investigation. Background Art

[0002] Measuring equipment is a general term for measuring instruments, measurement standards, reference materials, auxiliary equipment and the data necessary for measurement. Measuring equipment is the basis of technical, quality and economic work. Measuring equipment management is an important part of enterprise management. It is of great significance to improving product quality, saving energy and reducing consumption. It can directly or indirectly affect the product quality and economic benefits of the enterprise.

[0003] When conducting a land change survey, relevant personnel need to measure and investigate the basic conditions of the land and its appurtenances. Relevant personnel observe the distance, horizontal angle, vertical angle, and leveling of the land and its appurtenances by operating surveying instruments and other instruments.

[0004] The existing patent document with authorization announcement number CN213579345U installs a protective cover through a first fixing bolt to protect the measuring instrument, so as to prevent the device from accidentally slipping to the ground and failing to protect the measuring instrument when it needs to be protected, thereby causing damage. This effectively improves the use effect of the device and thus increases the service life of the device. However, when the measuring device is used, the measuring instrument is taken out of the outside of the box body and assembled on the outside. At the same time, when the measurement is completed, it needs to be disassembled and put into the inside of the box body. This makes the operation very cumbersome and cannot be carried away at the same time, resulting in poor portability. To this end, we provide a portable measuring device for land change survey to solve the above problems. Utility Model Content
