For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0032] Referring to Figs. 1 to 4 The embodiment provides a hinge capable of adjusting the mounting angle of a window sash, comprising a window frame mounting plate 1 and an opening and closing mechanism 2, the opening and closing mechanism 2 has an opening and closing end 20 and a connecting end 21, the opening and closing mechanism 2 comprises a long arm 3, a middle arm 4, a supporting arm 5 and a cantilever 6, the supporting arm 5 is rotatably provided with a window sash guide 8 at one end through a rotating shaft 7, a damping member 9 is sleeved on the rotating shaft 7, the window sash guide 8 is rotatably arranged on the damping member 9, a first inner hexagonal screw 90 for tightening the window sash guide 8 and the damping member 9 is arranged at the top of the window sash guide 8, so that the window sash guide 8 can be fixed on the damping member 9, and the window sash guide 8 can be rotated to the required angle position through the damping member 9.

[0033] In order to fix the window sash guide 8 and the damping member 9 at a certain position of the rotating shaft 7, the rotating shaft 7 has a step 70 at the lower part, the bottom of the window sash guide 8 is arranged at the step 70, and the bottom of the rotating shaft 7 is fixed on the supporting arm 5, and the bottom of the rotating shaft 7 can be connected with the supporting arm 5 in a threaded manner.

[0034] The sash guide 8 further comprises a guide body 80 and guide rails 81 formed on both sides of the guide body 80. The guide body 80 is provided with an axle hole 82 through which the rotating shaft 7 passes. The axle hole 82 is arranged along the length direction of the guide body 80. The guide rails 81 are provided with second inner hexagonal screws 83 for fastening the sash guide 8 to the sash.

[0035] In some embodiments, one side of the window frame mounting plate 1 is provided with a sliding groove 10 in which a sliding member 11 is slidingly arranged. The opposite ends of the long arm 3 are hingedly connected to the window frame mounting plate 1 and the supporting arm 5, respectively. The opposite ends of the middle arm 4 are hingedly connected to the sliding member 11 and the supporting arm 5, respectively. The opposite ends of the cantilever arm 6 are hingedly connected to the sliding member 11 and the supporting arm 5, respectively. When the sliding member 11 slides along the sliding groove 10, the opening and closing end 20 is brought into an open state or a coincident state relative to the window frame mounting plate 1. The hinge points between the long arm 3, the middle arm 4, the cantilever arm 6 and the supporting arm 5 are all different. It can be understood that the window frame mounting plate 1 is installed in the window frame, and the opening and closing mechanism 2 is installed on the sash. By sliding the sliding member 11 along the sliding groove 10, the opening and closing end 20 of the opening and closing mechanism 2 is brought into an open state relative to the window frame mounting plate 1, and at this time the sash is opened relative to the window frame. By sliding the sliding member 11 along the sliding groove 10, the opening and closing end 20 of the opening and closing mechanism 2 is brought into a coincident state relative to the window frame mounting plate 1, and at this time the sash is closed relative to the window frame.

[0036] In order to form a sliding groove 10 on the window frame mounting plate 1 for the sliding member to slide, a folding plate 12 is arranged on one side of the upper surface of the window frame mounting plate 1. The folding plate 12 is an integral structure with the window frame mounting plate 1 and is formed on the window frame mounting plate by bending. The folding plate 12 and the window frame mounting plate 1 form the sliding groove 10 for the sliding member 11 to slide therebetween. One end of the sliding groove 10 is open, and the other end is provided with a limiting structure. The limiting structure is a limiting pin 12 which passes through the folding plate 12 and is fastened on the window frame mounting plate 1. When the sliding member 11 slides to the limit position, the opening and closing mechanism will not rotate beyond the limit position relative to the window frame mounting plate 1, thereby avoiding damage caused by excessive rotation of the hinge.

[0037] In some embodiments, the sliding piece 11 comprises a sliding piece body 110 slidingly arranged in a sliding groove, a first wear-resistant sheet 111 formed on one side of the sliding piece body, a second wear-resistant sheet 112 hingedly arranged at one end of the sliding piece 11, a support 113 hingedly arranged at one end of the middle arm 4 on the first wear-resistant sheet 111, and the cantilever 6 is fixed on the second wear-resistant sheet 112. The sliding piece 10, the first wear-resistant sheet 111 and the second wear-resistant sheet 112 are all made of nylon material.
