A positioning and adjustment structure for precision optical instruments

Abstract

The present application belongs to the technical field of optical instrument positioning and debugging, and particularly relates to a positioning and debugging structure for precise optical instruments, comprising multiple telescopic rods, which are provided with connecting mechanisms for detachably placing laser levels. The connecting mechanisms comprise fixing assemblies connected with the multiple telescopic rods, the fixing assemblies are provided with connecting arms, the connecting arms are respectively provided with leveling assemblies and traction lifting assemblies, and the traction lifting assemblies are used for lifting the laser levels. The leveling assemblies comprise leveling seats fixedly installed at one end of the connecting arms, and the leveling seats are rotatably connected with universal balls at lower sides. The present application relies on the principle of gravity center collinearity to automatically and quickly form a rigid horizontal supporting surface for the horizontal reference plate under the action of its own gravity, completely gets rid of the dependence on the vertical state of the multiple telescopic rods, effectively offsets the concentricity deviation caused by the wear of the telescopic rods and the tilting influence caused by the unevenness of the construction site, and ensures the measurement accuracy of the laser level.
