Description

Technical Field

[0001] This utility model relates to an auxiliary component for optical instruments, specifically to a portable electromechanical quick-release component for a precision optoelectronic turntable. Background Technology

[0002] With the development of photoelectric theodolite measurement technology, related industries have placed demands on photoelectric precision turntables for rapid assembly and disassembly, easy transportation, and concealment. Unlike other equipment, photoelectric theodolites require extremely high repeatability accuracy before and after assembly and disassembly of their axis systems, typically on the order of seconds. The load end of the axis system often requires numerous cables to be threaded through it. When the cables rotate, they generate winding torque, which can interfere with the turntable's speed stability and thus affect its accuracy. Therefore, strict management of cable routing is essential to reduce the winding torque generated by the cables during axis rotation. Furthermore, the sealing of the axis system during installation must be considered in various field testing environments. Consequently, traditional photoelectric turntables typically have a fixed connection between the turntable end and the load end, which does not support rapid assembly and disassembly during transportation and field testing.
