Description

Technical Field

[0001] The utility model relates to an engineering distance meter, in particular to an engineering distance meter with high stability, belonging to the technical field of engineering distance measurement. Background Art

[0002] With the development of market technology, distance meters play a wide range of roles in daily life and scientific and technological innovation. Their precise measurement and tiny errors have brought us great economic benefits. In terms of construction engineering, good distance measurement is particularly important and plays a more prominent role in improving the capacity of infrastructure projects.

[0003] A portable laser rangefinder with high stability is disclosed in the Chinese patent application disclosure CN215526116U. An adjustable mechanism is added to the laser rangefinder, and the height can be adjusted according to the needs of use, which is convenient for measurement. At the same time, the components of the laser rangefinder can be disassembled, assembled when in use, and disassembled when carried, which is convenient for carrying and transportation. At the same time, a horizontal adjustment mechanism is added to the bottom of the laser rangefinder. After assembly and placement, the horizontal adjustment is performed, and it is convenient to fix it. While improving stability, it can also improve the accuracy of measurement and facilitate better operation.

[0004] In the solution of the above patent, when the height of the rangefinder increases, the upper part of the rangefinder and the fixed rod will cause the overall center of gravity to move upward. The upward shift of the center of gravity will affect the stability of the rangefinder, because the higher the center of gravity, the farther the upper part of the rod is from the base, and the torque generated will be greater. When the rangefinder and the fixed rod are subjected to external forces such as wind, vibration or other environmental factors, the swing and overturning torque generated will increase, resulting in poor stability. In addition, if the device is accidentally dropped or the fixed rod is hit during use, the rangefinder will fall to the ground, causing serious damage to the rangefinder. Utility Model Content
