【Detailed ways】

Below in conjunction with accompanying drawing, the utility model is further described:

As shown in Figures 1 to 4, a double-slider heavy-duty outward-opening window sliding brace hinge includes a chute 1, a short rod 2, a middle rod 3, a long rod 4 and a support arm 5. The chute 1 slides on Connected with two independently slidable first slider 6 and second slider 7, one end of the long rod 4 is rotatably connected with the first slider 6, and the other end is rotatably connected with the middle of the support arm 5. The rod 3 crosses the short rod 2 and the middle rod is supported at the bottom of the short rod 2, one end of the short rod 2 is rotatably connected with one end of the support arm 5, and one end of the middle rod 3 is rotatably connected with the long rod 4 and the rotary connection The point is between the rotational connection points at the ends of the long rod.

One of the other end of the short rod 2 and the other end of the middle rod 3 is rotatably connected with the second sliding block 7 , and the other is rotatably connected with the chute 1 . In the embodiment shown in FIG. 4 , the other end of the short rod 2 is rotatably connected with the second sliding block 7 , the other end of the middle rod 3 is rotatably connected with the chute 1 , the first sliding block 6 and the second sliding block 7 are rotatably connected. The two sliding blocks 7 are respectively located on the same side of the rotational connection point of the middle rod 3 and the chute 1, then when opening and closing, the sliding support hinge takes the rotational connection point of the middle rod 3 and the chute 1 as the base point, The first slider 6 and the second slider 7 slide relative to the base point in the chute 1, and the link mechanism composed of the short rod 2, the middle rod 3, the long rod 4 and the support arm 5 rotates with the middle rod 3 as the rotation radius, and rotates The radius is small, the sliding distance of the first sliding block 6 and the second sliding block 7 is short, and the structure strength is good.
