Description

Technical Field

[0001] This utility model relates to the technical field of hinges, and in particular to an adjustable top-hung window hinge. Background Technology

[0002] Top-hung windows are a type of window where the sash rotates around an upper horizontal axis via hinges and opens outwards. They are widely used due to their advantages such as good ventilation, good sealing, sound insulation, and heat preservation. Hinges, as the main component connecting the window sash and the window frame, play a supporting and transmission role for the window sash. During installation, the hinges need to be fixed to the window sash first, and then the window sash is lifted to install the hinges onto the window frame. However, existing top-hung hinges do not have an adjustment mechanism and rely on manual adjustment, which leads to low precision and easily causes the window sash and window frame to be positioned too high or too low, resulting in the window sash not closing properly or even damaging the window sash. Summary of the Invention

[0003] The present invention provides an adjustable top-hung window hinge to solve the aforementioned problems.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an adjustable top-hung window hinge, comprising a window sash fixing rod, wherein the top of the window sash fixing rod is provided with a plug-in plate that is inserted into the window sash hardware groove, the window sash fixing rod is provided with a connecting screw and a strip groove, the bottom of the plug-in plate is provided with a sliding groove and an eccentric nail, the connecting screw is slidably connected to the sliding groove, the eccentric nail is rotatably connected to the plug-in plate, and the eccentric nail is disposed in the strip groove.

[0005] Furthermore, the sliding groove is parallel to the length direction of the window sash fixing rod, and the sliding groove is perpendicularly distributed in the strip groove.

[0006] Furthermore, the eccentric nail includes a top cap and a connecting post disposed at the eccentric position of the top cap. The connecting post is rotatably connected to the plug-in plate. The top cap is disposed in the strip groove, and the diameter of the top cap corresponds to the width of the strip groove.

[0007] Furthermore, both the plug-in plate and the window sash fixing rod are provided with plug-in parts for plugging into the window sash hardware groove.

[0008] Furthermore, the window sash fixing rod is provided with mounting holes.

[0009] Furthermore, it also includes a window frame fixing rod, which is movably connected to the window sash fixing rod via a connecting rod, and the bottom of the window frame fixing rod is provided with a positioning part corresponding to the window frame hardware groove.

[0010] Compared with the prior art, the beneficial effects of this utility model are: by using the plug-in plate set on the window sash fixing rod, the plug-in plate is inserted into the window sash hardware groove, and by turning the eccentric nail, the window sash fixing rod slides along its length direction on the plug-in plate, thereby achieving the effect of adjusting the window sash and preventing improper installation and damage to the window sash.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] As shown in the attached diagram, this utility model discloses an adjustable top-hung window hinge, comprising a window sash fixing rod 1. The top of the window sash fixing rod 1 is provided with a connecting plate 2 that inserts into the window sash hardware groove. The connecting plate 2 is L-shaped, with one side parallel and close to the window sash fixing rod 1, and the other side vertically positioned at one end of the window sash fixing rod 1. A locking piece for connecting the window sash is rotatably mounted on the vertical side. It should be noted that the window sash profiles on each side of the top-hung window have hardware grooves, which is an existing structure. The hinge is installed on the left and right sides of the top-hung window. The window sash fixing rod 1 is provided with connecting screws 101 and a strip groove 100. The connecting plate 2... The bottom is provided with a sliding groove 200 and an eccentric nail 201. The connecting screw 101 is slidably connected to the sliding groove 200, and the eccentric nail 201 is rotatably connected to the plug-in plate 2. The eccentric nail 201 is set in the strip groove 100. The connecting screw 101 is threaded onto the window sash fixing rod 1. The window sash fixing rod 1 and the plug-in plate 2 are temporarily connected by the connecting screw 101 and the sliding groove 200, so that the plug-in plate 2 can slide relative to the window sash fixing rod 1 along the length direction of the sliding groove 200. After adjustment, the connecting screw 101 is tightened so that the connecting screw 101 and the plug-in plate 2 clamp and fix the window sash fixing rod 1. By using the plug-in plate 2 provided on the window sash fixing rod 1, the plug-in plate 2 is inserted into the window sash hardware groove, and by turning the eccentric nail 201, the window sash fixing rod 1 slides along its length direction on the plug-in plate 2, thereby achieving the effect of adjusting the window sash and preventing improper installation and damage to the window sash.

[0019] Specifically, the sliding groove 200 is parallel to the length direction of the window sash fixing rod 1, and the sliding groove 200 is perpendicular to the strip groove 100, that is, the strip groove 100 is perpendicular to the window sash fixing rod 1.

[0020] Specifically, the eccentric nail 201 includes a top cap 2011 and a connecting post 2012 disposed at the eccentric position of the top cap 2011. The connecting post 2012 is rotatably connected to the plug-in plate 2. The top cap 2011 is disposed in the strip groove 100, and the diameter of the top cap 2011 corresponds to the width of the strip groove 100. The top cap 2011 is also provided with a screwing part. The plug-in plate 2 is provided with a connecting hole, and the connecting post 2012 is disposed in the hole. The end of the connecting post 2012 can be riveted to prevent the connecting post 2012 from detaching from the plug-in plate 2. By rotating the eccentric nail 201, the top cap 2011 is used to push the strip groove 100, thereby pushing the window sash fixing rod 1 to slide along its length direction on the plug-in plate 2, thus realizing the height adjustment of the window sash.

[0021] Specifically, both the plug-in plate 2 and the window sash fixing rod 1 are provided with plug-in parts 120 for plugging into the hardware groove of the window sash. The plug-in parts 120 protrude above the plug-in plate 2 and the window sash fixing rod 1. The window sash fixing rod 1 is provided with mounting holes 111. The plug-in parts 120 are inserted into the hardware groove of the window sash to temporarily fix the hinge and the window sash. After adjustment, the window sash is fixedly connected by screws through the mounting holes 111.

[0022] Specifically, it also includes a window frame fixing rod 3, which is movably connected to the window sash fixing rod 1 via a connecting rod. The bottom of the window frame fixing rod 3 is provided with a positioning part 300 corresponding to the window frame hardware groove. The positioning part 300 can be formed by stamping. The downward protruding positioning part 300 is formed by stamping the window frame fixing rod 3 downward. The width of the positioning part 300 is equal to the groove width of the window frame hardware groove.

[0023] The above embodiments are preferred embodiments of this utility model. All structures similar to this utility model and equivalent changes thereof should fall within the protection scope of this utility model.
