Placing Widgets on a ScrollArea Pyqt5?

Question

PyQt

I have a problem with ScrollArea, in short I have this set of widgets:

I can have up to 20 such sets, they must be arranged vertically, so I need to place them in a SCrollArea, but I can't figure out how ScrollArea works, I found one example ( https://codeloop.org/pyqt5-gui-creating-qscrollarea/ ), but it does not suit me because only two widgets are repeated in it.
Tell me how can I place my widgets exactly in the form in which they are presented?
