[0030] Refer to Figures 1 to 4 , an adjustable hinge, including a frame edge connecting piece 100, a sash edge connecting piece 200, an adjustment shaft 300, and an adjustment screw 400.

[0031] Specifically, the first connecting part 110 is provided with a first shaft through hole 111, and the first shaft through hole 111 is set as a circular hole structure penetrating the first connecting part 110.

[0032] One of the first connecting parts 110 is provided with a threaded hole which communicates with a first shaft through hole 111 provided in the first connecting part 110. A set screw 112 is threadedly connected in the threaded hole of the first connecting part 110. In other embodiments, threaded holes may also be provided in both first connecting parts 110, and those skilled in the art can set the number and position of the threaded holes according to actual needs.

[0033] Specifically, in this embodiment, the frame edge connecting member 100 is provided with a frame clamping groove 120 for clamping the frame edge connecting member 100 to a fan frame or a door frame, so that the frame edge connecting member 100 can be preliminarily fixed to facilitate subsequent fixing of the frame edge connecting member 100 to the fan frame or the door frame.

[0034] The fan edge connecting member 200 is provided with a fan clamping protrusion 220 for clamping the fan edge connecting member 200 to a window sash or a door, so that the fan edge connecting member 200 can be preliminarily fixed to facilitate subsequent fixing of the fan edge connecting member 200 to the window sash or the door.

[0035] The fan edge connecting member 200 is provided with a plurality of second connecting parts 210. Specifically, in this embodiment, the number of the second connecting parts 210 is set to one. In other embodiments, the number of the second connecting parts 210 of the fan edge connecting member 200 can also be set to two, three, etc. Those skilled in the art can select the number of the second connecting parts 210 according to actual needs.

[0036] The second connecting part 210 is arranged between two adjacent first connecting parts 110. The second connecting part 210 is provided with a second shaft through hole 211 which is a strip-shaped hole structure penetrating the second connecting part 210, and the second shaft through hole 211 communicates with the first shaft through hole 111.

[0037] The second connecting part 210 is further provided with a screw insertion hole 212 which communicates with the second shaft through hole 211, and the screw insertion hole 212 is a rectangular through hole structure.

[0038] The second connecting part 210 is further provided with an adjustment hole 213 which is a conventional round hole structure. In other embodiments, the adjustment hole 213 can also be set to a rectangular hole or a hexagonal hole structure. Those skilled in the art can select the specific shape of the adjustment hole 213 according to actual needs, and the adjustment hole 213 is used for a tool to pass through.

[0039] The adjusting shaft 300 has a circular shaft structure, and the adjusting shaft 300 passes through the first shaft through-hole 111 and the second shaft through-hole 211. A threaded hole is provided in the middle of the adjusting shaft 300, and the adjusting screw 400 is threadedly connected to the threaded hole provided in the adjusting hole 213. The head of the adjusting screw 400 is correspondingly arranged with the adjusting hole 213. After the tool passes through the adjusting hole 213, it is clamped with the wrenching groove at the head of the adjusting screw 400. The tool can rotate the adjusting screw 400. Since the adjusting shaft 300 is threadedly connected to the adjusting screw 400, when the adjusting screw 400 rotates, the adjusting shaft 300 will move axially along the adjusting screw 400 within the second shaft through-hole 211, thereby solving the problem that the window sash or door will tilt towards the handle side of the door leaf due to the action of gravity.

[0040] A set screw groove 310 is provided at one end of the adjusting shaft 300, and the tail of the set screw 112 is arranged in the set screw groove 310, and the bottom of the set screw groove 310 abuts against the tail end of the set screw 112.

[0041] The hinge in this embodiment is an adjustable three-wing hinge. The materials of the frame-side connecting piece 100 and the sash-side connecting piece 200 are both aluminum alloy 6061-T6, and the material of the adjusting shaft 300 is stainless steel 304. After testing, the maximum load-bearing weight of this hinge is 200 kg, which is applicable to standard European-standard 20-hole aluminum alloy doors and windows.

[0042] This hinge has an adjustable rotating shaft structure. The adjusting shaft 300 of this hinge sequentially penetrates into one of the first connecting parts 110 of the frame-side connecting piece 100, one of the gaskets 500, and the second connecting part 210 of the sash-side connecting piece 200. There is a certain gap between the gasket 500 and the second connecting part 210 to install the adjusting screw 400. Subsequently, the threaded hole of the adjusting shaft 300 is located between the gasket 500 and the sash-side connecting piece 200. After screwing the M6*18 socket head cap screw 112 (adjusting screw 400) into the adjusting shaft 300, the gasket 500 is fitted to the first connecting part 110, and the second connecting part 210 is fitted to the gasket 500. Another gasket 500 is placed between the second connecting part 210 and the other first connecting part 110. Subsequently, the adjusting screw 400 is inserted into the screw insertion hole 212 of the sash-side connecting piece 200, so that the wrenching groove at the head of the adjusting screw 400 is concentrically arranged with the adjusting hole 213 of the sash-side connecting piece 200. At this time, the end of the adjusting shaft 300 passes through another gasket 500 and penetrates into the other first connecting part 110. Subsequently, the set screw 112 is screwed into the first connecting part 110, so that the tail end of the set screw 112 abuts tightly against the bottom of the set screw groove 310 of the adjusting shaft 300 to complete the locking of the adjusting shaft 300. Subsequently, the two decorative covers 130 are respectively installed at the ends of the first connecting part 110, and the assembly of this adjustable hinge can be completed.

[0043] By driving the adjusting screw 400 to rotate through a tool, relative movement between the adjusting shaft 300 and the sash edge connecting member 200 can occur, which can solve the phenomenon that the window sash or door sash will tilt towards the handle side of the door leaf due to the action of gravity. This hinge is an adjustable rotating shaft hinge, which can be adjusted left and right by 1.5 mm, has a wide range of applications, and is firm and durable.

[0044] The above has specifically described the preferred embodiments of the present invention, but the present invention is not limited to the described embodiments. Those skilled in the art can also make various equivalent variations or substitutions without departing from the spirit of the present invention, and these equivalent variations or substitutions are all included within the scope defined by the claims of this application.
