Wherein, articulated trailing arm 3 of quarter butt 2 one end, other end sliding connection spout 1, articulated trailing arm 3 of quarter butt 4 one end, the other end rotates and connects spout 1, and the setting of first bracing piece 5 has supported trailing arm 3 better, has increased the bearing and the stability of trailing arm 3. Further, the first supporting rod 5 forms two quadrangles with the chute 1, the short rod 2, the bracket arm 3 and the long rod 4, and the first supporting rod 5 is a shared edge. The bracket arm 3 drives the short rod 2, the first supporting rod 5 and the long rod 4 to be linked together with the opening and closing of the door and window sashes, and the opening and the closing are smooth.
Preferably, the first supporting rod 5 is parallel to the short rod 2 and the long rod 4, after bearing stress, the force transmission direction is consistent, the stress of the supporting arm 3 is easier to disperse, and the bearing safety of the hinge is improved.
In one embodiment of the present utility model, one of the first support rod 5 and the long rod 4 is slidably and rotatably connected to the chute 1, and the other is rotatably connected to the chute 1. For example, the long rod 4 is hinged with the chute 1, the hinged end is fixed, the first supporting rod 5 is connected with the chute 1 in a sliding manner and can rotate, or alternatively, the first supporting rod 5 is hinged with the chute 1, the hinged end is fixed, and the long rod 4 is connected with the chute 1 in a sliding manner and can rotate. The hinge end fixed by the hinge linkage assembly is flexible to set, and can be applicable to more frame profiles.
In order to further improve the bearing performance of the hinge, a supporting arm 6 is arranged between the chute 1 and the long rod 4, the short rod 2 and the first supporting rod 5 are hinged and supported by the supporting arm 6, one end of the supporting arm 6 is hinged and supports the long rod 4, and the other end is connected with the chute 1 in a sliding way. The support arm 6 is positioned below the short bar 2, the long bar 4 and the first support bar 5 to improve the supporting force to the short bar 2, the long bar 4 and the first support bar 5.
