Description

Technical Field

[0001] The utility model belongs to the technical field of doors and windows, and in particular relates to an anti-sway hinge. Background Art

[0002] In order to allow the window sash to have both the functions of casement opening and inward tilting opening, it is necessary to configure upper and lower hinge components to provide the window sash with opening movement and control the movement trajectory of the window sash.

[0003] When the window is tilted inwards, the window sash unfolds toward the indoor side. There are two types of products on the market: top-hung and bottom-hung. For example, for the bottom-hung tilt window, its upper hinge has a conventional casement hinge structure and a long rocker arm between the hinge assembly and the window sash. The long rocker arm is hinged to the hinge assembly and the window sash connecting assembly at the same time, and the window sash is hung open by swinging and unfolding the long rocker arm.

[0004] At the same time, in order to prevent the window sash from being too close to the vertical window frame when the window is opened and affecting the wall decoration work, such as tiling work, the window designer will try to make the window sash move away from the vertical window frame when the window is opened and opened. To achieve this movement, it is necessary to open a long groove on the horizontal window frame connecting plate to provide the hinge with the function of sliding movement. However, due to the existence of the long groove, the lateral gap between the hinge assembly and the long rocker arm will become larger, that is, the long rocker arm has a larger lateral swing space than the horizontal window frame mounting plate, which will further reduce the sealing of the window corners and even cause water leakage.
