Description

Technical Field

[0001] The utility model mainly relates to the technical field of frame folding, in particular to a folding mechanism for a large frame. Background Art

[0002] When the vertical droplet distribution measuring instrument conducts a droplet collection test, the panel for collecting droplets needs to be moved due to changes in the test site. Therefore, the panel for collecting droplets is designed to be foldable and retractable. In order to control the experimental variables, it is necessary to ensure the surface flatness of the panel after folding and unfolding. The traditional folding structure does not adequately control the flatness of the spliced ​​panels after unfolding, so it is necessary to optimize the structure of the foldable frame for installing the panel.
