Description

Technical Field

[0001] The invention relates to a hinge structure, in particular to an upper-hung hidden hinge structure with visible adjustment. Background Art

[0002] At present, most of the outward-opening top-hung windows on the market are installed on the window frame through hinge connecting rods. Therefore, the top-hung turning of the window sash is achieved through the gap between the upper hinge connecting rods. This method is not only complex in structure, difficult to install, and structurally unstable, but also not very smooth when the top-hung turning is performed, which greatly limits the use of the window sash. During the use of the window sash, the left and right overlap amount and the up and down adjustment of the window sash require people to stand at the window, bend over and lean out of the window, and use their hands to touch and feel the position for adjustment. This method is not only difficult to adjust, but also has safety hazards. Summary of the invention
