AI Technical Summary

Technical Problem

The switching between the bent state of the support column and the vertical state of the existing three-dimensional scanner requires manual operation of multiple card blocks, and the process is cumbersome and lacks convenience.

Method used

Adopt a T-shaped slide chute and slider structure, combined with a state switch, including a fixed ruler, a rotor, a connector, a positioning shaft, a positioning spring and an operating rod. Through the cooperation of the slider and the support column, convenient state switching of the support column is achieved. , reduces dependence on card blocks.

Benefits of technology

The convenient switching between the bending state and the vertical state of the support column is achieved, the operation efficiency is improved, and the cumbersome process of swinging multiple blocks one by one in the background technology is avoided, which enhances the fineness of the scanner scanning the top of the object.

Abstract

The present invention relates to the field of three-dimensional construction, and in particular to a projection optical system of 3D structured light and a three-dimensional scanner based thereon. The structure of a support column from bottom to top comprises a fixed column, a plurality of hinged columns and an adjusting column, and the three columns are rotatably arranged adjacent to each other. The fixed column and the plurality of hinged columns all have the function of rotating toward a storage table. The outer walls of the adjacent fixed column, the plurality of hinged columns and the adjusting column are fixedly connected with an independent tie belt, and the adjusting column can at least rotate to a horizontal state. The state switcher comprises a fixed ruler, a rotating wheel, a connecting piece, a positioning shaft, a positioning spring, and an operating rod. The fixed ruler is slidably inserted into a sliding groove, and the operating rod is fixedly connected to the fixed ruler and extends out of the sliding groove. The rotating wheel is rotatably connected to the fixed ruler, the connecting piece fixes the positioning shaft and the rotating wheel, and the elastic force of the positioning spring can pull the positioning shaft into the limiting groove, so that the switching between the bending state and the vertical state of the support column is convenient.
