Specifically, the linkage hinge 50 is located between the first and second driving hinges 301 and 302, and the linkage hinge 50 is located closer to the second driving hinge 302, so as to ensure that both sides of the window sash 300 can be subjected to equal force to be opened in parallel.

In another embodiment, two or more linkage hinges 50 may be provided, respectively adapted to the first and second drive hinges 301, 302, to achieve a more stable opening and closing of the window sash 300.
In the present embodiment, the preferred linkage hinge 50 is a linkage hinge 50 structure that can form a "parallelogram" shape with the first transmission hinge 301. When the window sash 300 is opened or closed, the rotation direction of the link hinge 50 is the same as the rotation direction of the first transmission hinge 301, and the rotation angle and the rotation distance of the link hinge 50 are respectively equal to the rotation angle and the rotation distance of the first transmission hinge 301. The linkage hinge 50 has a simple structure, is easy to realize and is convenient to operate.
Of course, the present solution is not limited to the specific arrangement of the first transmission hinge 301, and the window sash 300 may be pushed by an "X" shaped hinge structure, and the function of parallel opening of the window sash 300 may be achieved. As long as the auxiliary transmission structure capable of opening the window sashes 300 in parallel is realized, all simple variations and changes of the scheme should fall within the protection scope of the present invention.
It should be noted that, without the linkage hinge 50, the first transmission hinge 301 and the second transmission hinge 302 form a linkage structure in a shape of "parallelogram", and the two sets of hinges are pushed or retracted synchronously, so as to realize the function of pushing the window sash 300 in parallel. In this solution, the first sliding frame 10 and the second sliding frame 20 are respectively fixed at two ends of the bottom of the window frame 200, and when the window sash 300 is closed, the first transmission hinge 301 drives the window sash 300 to protrude from the edge of the window frame 200, so that the window sash 300 is not aligned with the window frame 200, and the window is not attractive.
Further, it is preferable that the first transmission hinge 301 and the second transmission hinge 302 are in a transmission hinge combination structure of an inverted splayed shape. When the window sash 300 is opened or closed, the rotation direction of the first transmission hinge 301 is opposite to the rotation direction of the second transmission hinge 302, and the rotation angle and the rotation distance of the first transmission hinge 301 are equal to the rotation angle and the rotation distance of the second transmission hinge 302, respectively. The transmission hinge structure design of the inverted splayed can enable the second transmission hinge 302 to slide in the window frame in the rotating process, so that transmission consistency between the first transmission hinge 302 and the first transmission hinge 301 is ensured, and meanwhile, one side of the second transmission hinge 302 driving the window sash can be prevented from protruding out of the window frame.
Based on the "inverted splayed" load bearing transmission 100, the inventors performed repeated opening and closing performance tests. The specific test is as follows:
The load-bearing transmission device 100 with the shape of the inverted figure is installed on the window sash 300 with the weight of 100kg (the maximum weight of the window sash 300 which can be installed by adopting other load-bearing transmission devices 100 with the same grade of material is 60 kg);
The test is opened and closed repeatedly, 25000 cycles are opened and closed in a translation state, 10000 cycles are opened and closed in a suspension state, and all operation functions are normal and satisfy:
a) The rotating moment of the handle or the operating device for operating the hardware system is not more than 10 N.m, and the force applied to the handle is not more than 100N;
b) After the test, the distance variation value between the frame and the fan in the direction perpendicular to the plane of the window sash 300 is smaller than 1mm; the force pushing into the frame should not be greater than 120N when the sash 300 is closed in the flat-open position.
The above experimental conclusion can prove that the bearing transmission device 100 of the present embodiment can greatly increase the bearing quality.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the invention.
