Please refer to fig. 1 to 8. An embodiment of the utility model provides a hinge for door and window, it includes bottom plate 1, mount pad 2, bearing arm 3, first support arm 4 and second support arm 5, the bottom plate 1 the mount pad 2 bearing arm 3 with first support arm 4 constitutes four-bar linkage, 5 auxiliary stay of second support arm increase bearing capacity, strengthen overall structure's atress. Specifically, when door and window opened a wide angle, if bearing arm 3 with mount pad 2 is located same straight line, bottom plate 1 the mount pad 2 bearing arm 3 with first support arm 4 forms the triangle-shaped space, second support arm 5 will the triangle-shaped space falls into two similar little triangle-shaped spaces, has increased the support between the structure, plays stable in structure, improves the beneficial effect of bearing.

The bottom plate 1 is connected with a frame 9, and the mounting seat 2 is connected with a fan 10. The frame material end of the bearing arm 3 is hinged to the base plate 1, and the fan material end of the bearing arm 3 is hinged to the mounting base 2. The frame material end of the first supporting arm 4 is hinged to the base plate 1, and the fan material end of the first supporting arm 4 is hinged to the mounting seat 2. One end of the second supporting arm 5 is hinged to the middle section of the bearing arm 3, and the other end of the second supporting arm 5 is hinged to the middle section of the first supporting arm 4.

Specifically, the fan material end of the first support arm 4 is provided with a first groove 41, and the hinged end of the second support arm 5 and the bearing arm 3 is provided with a recessed port 51 matched with the fan material end of the first support arm 4 and a second groove 52 matched with the first groove 41. In particular, the indentation 51 is a semicircular notch. When door and window closes, first support arm 4 with second support arm 5 is folding, first recess 41 keeps away the space with second recess 52 each other, and when folding, first support arm 4 with the width of second support arm 5 with the width phase-match of bottom plate 1, first recess 41 with second recess 52 festival has reduced overall structure's volume.

Specifically, a sliding notch 53 is formed in one end, hinged to the first support arm 4, of the second support arm 5, and the second support end passes through the sliding notch 53 through a rivet to be hinged to the first support arm 4. The extending direction of the sliding groove opening 53 is matched with the moving track orientations of the first supporting arm 4 and the second supporting arm 5, and the sliding groove opening has a certain degree of freedom in the process of moving the hinge for doors and windows, so that the sliding groove opening moves more smoothly.
