AI Technical Summary
Technical Problem
The focusing mechanism of existing infrared imaging equipment is relatively large, which limits the diversity of appearance design and miniaturization. It also cannot be operated with one hand, and its flexibility and user experience need to be improved.
Method used
It adopts a focusing bracket, focusing nut and focusing screw structure. The focusing screw extends to the image side of the moving lens and provides pre-tension force in combination with the focusing spring, so as to realize one-handed operation and high-precision focusing.
Benefits of technology
This design achieves a smaller radial dimension for the lens, supports one-handed focusing, improves usability and focusing accuracy, and enhances the user experience.

Abstract
The utility model relates to a lens, including movable lens and focusing structure, focusing structure includes focusing support, focusing silk mother and focusing screw rod, focusing support fixed connection in movable lens's lens barrel, focusing silk mother sets up on focusing support and its axial parallel movable lens's axial, focusing screw rod is screwed with focusing silk mother and sets up to movable lens's image side extension, the extension tail end of focusing screw rod is connected with the focusing hand wheel for driving its rotation around the own axis. In addition still provide a kind of imaging equipment using above-mentioned lens barrel, imaging chip is located between movable lens and focusing hand wheel. In the utility model, connecting focusing support on movable lens and connecting screw rod mechanism by focusing support, and focusing screw rod sets up to movable lens's image side extension, not only can realize long distance focusing, but also can make the radial dimension of lens smaller;Focusing hand wheel and the lens barrel of lens are relatively separated, more suitable for single-handed operation, and use experience is better.
