Description
Technical Field
[0001] This utility model relates to locks, and more particularly to a double-hook lock with a combination key for an invisible screen window. Background Technology
[0002] Many windows now use concealed screens, which are rolled up and installed in a roller box at the top of the window. When the window needs to be closed, the screen is pulled down so that the hooks on the screen frame can be hooked onto the window frame. However, this traditional method of fixing screens is very inconvenient in practice. The main problem is that it is difficult to hook and fix the screen, and it is easy to lose the ability to close it properly. In addition, the single hook method is not strong enough and has a relatively weak anti-theft capability. Summary of the Invention
