An embodiment of the utility model provides a window form, including window frame, casement and connect the hinge structure between window frame and casement, hinge structure's setting is convenient for the relative window frame of casement and is opened and close. Wherein, when the relative window frame of casement is opening the back, need fix the opening angle of casement, ensure that the casement can open in certain safe angle. Thus, it is a concern whether the hinge structure has a good positioning effect, i.e. the fixation of the opening angle of the sash. The following is a detailed structural description of the hinge structure.

Referring to fig. 1-3, fig. 1 illustrates a first schematic view of a hinge structure according to an embodiment of the present invention; fig. 2 is a second schematic view of a hinge structure provided by an embodiment of the present invention; fig. 3 is an exploded view of a hinge structure according to an embodiment of the present invention. An embodiment of the utility model provides a hinge structure for install between window frame and casement, including frame connection piece 10, fan connection piece 20 and first connecting rod 30. Wherein, the frame connecting piece 10 is used for fixing on the window frame, the sash connecting piece 20 is used for fixing on the window sash, and the first connecting rod 30 is used for connecting between the sash connecting piece 20 and the frame connecting piece 10. Wherein, the frame connecting piece 10 is provided with a first sliding chute 11 extending along the length direction of the frame connecting piece, and the first end of the first connecting rod 30 is connected in the first sliding chute 11 in a sliding way; fan connection piece 20 is provided with the second spout 21 that extends along the length direction of self, and the second end sliding connection of first connecting rod 30 is in second spout 21, and is provided with the flexure strip in second spout 21, and the second end when first connecting rod 30 removes to flexure strip department, can with the flexure strip joint and then carry on spacingly to the relative removal of fan connection piece 20 of first connecting rod 30, realizes that the relative frame connection piece 10's of fan connection piece 20 removal is spacing. When the angle of the sash connecting piece 20 relative to the frame connecting piece 10 is fixed, the opening limit of the sash relative to the window frame is realized.

Specifically, the frame connecting piece 10 is fixed in a frame groove of the window frame, and the position of the frame connecting piece 10 is fixed relative to the window frame. The fan connecting piece 20 is fixed at the bottom of the window sash, the position of the fan connecting piece 20 is fixed relative to the window sash, and when the window sash is opened and closed relative to the window frame, the fan connecting piece 20 moves synchronously along with the window sash, so that when the moving angle of the fan connecting piece 20 is limited, the moving angle of the window sash is also limited. When the sash connecting piece 20 moves with the sash relative to the window frame, the first end of the first link 30 can move in the first sliding slot 11, and the second end of the first link 30 can move in the second sliding slot 21 to adapt to the open state of the sash.

As shown in fig. 1, for example, when one end of the frame connecting piece 10 having the first vertical folded plate is a first end of the frame connecting piece 10, the other end along the longitudinal extending direction of the frame connecting piece 10 is a second end of the frame connecting piece 10. Similarly, the end of the fan-shaped connecting piece 20 having the second vertical folded plate is the first end of the fan-shaped connecting piece 20, and the other end along the length extending direction of the fan-shaped connecting piece 20 is the second end of the fan-shaped connecting piece 20. Wherein the first vertical flap is intended to be connected to a first vertical edge of the window frame and the second vertical flap is intended to be connected to a second vertical edge of the sash. When the window sash needs to be opened, along with the gradual increase of the opening angle of the window sash relative to the window frame, the first end of the first connecting rod 30 can slide from the first end of the frame connecting piece 10 to the second end of the frame connecting piece 10 in the first sliding groove 11, and the second end of the first connecting rod 30 can slide from the second end of the sash connecting piece 20 to the first end of the sash connecting piece 20 in the second sliding groove 21. The elastic piece is provided at one end of the second slide groove 21 toward the first end of the fan attachment piece 20. At this moment, when the second end of first connecting rod 30 removed to the flexure strip department in second spout 21, with the flexure strip joint, and then spacing the relative removal of fan connecting piece 20 of second end to first connecting rod 30, the second end of first connecting rod 30 no longer removes in second spout 21 relative fan connecting piece 20 to it is spacing to utilize the pulling force of first connecting rod 30 to carry out the pivoted position of fan connecting piece 20, realizes spacing to the opening angle of casement.

That is to say, in this embodiment, through the joint of the elastic sheet that sets up in second spout 21 and the second end of first connecting rod 30, realize spacing the rotation of the relative frame connection piece 10 of fan connection piece 20, and then realize spacing the opening angle of the relative window frame of fan, promptly: the positioning of the opening position of the window sash is realized, the window sash is ensured not to be opened relative to the window frame any more, the opening angle of the window sash relative to the window frame is reduced, and the use safety of the window body is improved. Meanwhile, the second end of the first connecting rod 30 is clamped with the elastic sheet, so that the elastic sheet is elastically deformed during clamping to generate elastic potential energy. Therefore, when the window sash is closed relative to the window frame, and the second end of the first connecting rod 30 moves in the opposite direction relative to the second sliding groove 21, the extrusion force acting on the elastic sheet gradually disappears, so that the elastic potential energy of the elastic sheet is released to push the second end of the first connecting rod 30 to slide in the second sliding groove 21 in the opposite direction, so that the first connecting rod 30 can reset in time relative to the second sliding groove 21, the window sash is convenient to close, and the operation is more convenient.

It should be noted that the elastic piece may be disposed on one long side of the second sliding slot 21, and at this time, the other long side of the second sliding slot 21 and the elastic piece limit the sliding of the first connecting rod 30 together. Alternatively, elastic pieces are provided at both long sides of the first sliding chute 11 to limit the sliding of the first link 30 by the elastic pieces.
