Abstract
Description
Technical Field
[0001] This utility model relates to the field of window sash hinge technology, and in particular to a movable window sash hinge structure. Background Technology
[0002] Window sash hinges are used to connect window sashes to the window frame, enabling the window to rotate. Patent application number 202011457529.8 discloses a window sash hinge including a bottom groove component installed on a European standard frame groove. The bottom groove component has a through hole, and the edge of the through hole extends to a locking slot. The locking slot fits into the European standard frame groove, and the locking slot has a fastening hole for fixing, thus ensuring a secure connection between the bottom groove component and the European standard frame groove. The bottom groove component is quickly positioned on the European standard frame groove through the locking slot. The width of the third link matches the European standard C groove, and the third link can be directly inserted into the European standard C groove. The third link connects to the window sash in the horizontal direction, effectively improving assembly efficiency. However, this type of window sash hinge can only be used for the rotating connection between the window sash and the window frame. When dust and other debris accumulate at the connection point, it is difficult to clean, and long-term use can cause the window sash to become stuck and unable to rotate flexibly. Utility Model Content

The hinge assembly is slidably mounted on a slide rail, which is symmetrically fixed to the inner side of the window frame. The hinge assembly includes a first link, a second link, and a third link. The top end of the first link is hinged to the middle of the second link, and the top end of the third link is hinged to the middle of the first link. The bottom end of the first link is hinged to a first slider, and the bottom ends of the second and third links are connected to a second slider. Both the first and second sliders are slidably assembled within the slide rail. The top ends of the first and second links are connected to the window sash. When the window sash is opened, the first and second sliders can drive the window sash to slide along the slide rail.
[0007] In some embodiments, the bottom of the third link is hinged to the second slider, the bottom of the second link is hinged to a fourth link, and the other end of the fourth link is hinged to the second slider and located on one side of the third link.
[0008] In some embodiments, a limiting member is inserted into one end of the slide rail, and a limiting protrusion is provided on the inner wall of the other end. The second connecting rod is located above the fourth connecting rod and is also hinged to a fifth connecting rod. The other end of the fifth connecting rod is hinged to the third connecting rod, and the second connecting rod is fixed to the side of the window sash.
[0009] In some embodiments, the window frame is provided with a mounting groove, the back of the slide rail is fixed in the mounting groove, and when the window sash is open, the second connecting rod and the third connecting rod are vertically arranged, and the first connecting rod and the second connecting rod maintain an angle of 45°-60°.
[0010] In some embodiments, the first slider is close to the limiting protrusion, the second slider is close to the limiting member, and when the first slider slides to the limiting protrusion, the second slider is located at the middle position of the window frame.
[0011] (III) Beneficial Effects
[0012] This utility model provides a movable window sash hinge structure. A slide rail is installed inside the window frame. A slider that is slidably assembled in the slide rail is hinged to the first link, the second link, and the third link in the hinge assembly. This allows the window sash to slide along the window frame after it is opened, thereby moving the window sash to the middle position. This facilitates thorough cleaning of the inside of the window frame and prevents the window sash from becoming immobile due to the accumulation of debris inside the window frame after long-term use.
