[0003] With the continuous progress of the door and window industry and the pursuit of the improvement of the life quality of people, the design of the sash tends to be larger in size to adapt to the modern architectural aesthetics and lighting requirements, and in order to support these large-size sashes, two independent hinges are usually installed on the left and right sides of the sash, and the hinges work cooperatively to ensure the stable opening and closing of the sash. Figure 7 and Figure 8 A sliding groove 801 is formed on the spacer sleeve, and a through hole 802 is formed on the side wall on both sides of the sliding groove 801. In order to avoid interference of the bolt 8 when the connecting rod 7 slides, a stroke waist groove 701 is designed on the connecting rod 7. When assembling, the connecting rod 7 is inserted through the sliding groove, the stroke waist groove 701 is coincided with the upper and lower through holes 802, the front end of the bolt 8 is inserted through the upper through hole, the stroke waist groove 701 and the lower through hole, and then is locked on the window frame, so that the spacer sleeve is fixed, and the bolt head 803 is located on the upper surface of the spacer sleeve. However, the stroke waist groove will weaken the material thickness of the connecting rod 7 in the area, thereby reducing the structural strength. Thus, when a large load is borne or impacted, the connecting rod 7 can be more easily broken or deformed due to the existence of the stroke waist groove. SUMMARY

[0020] The technical scheme in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the range of protection of the utility model.

[0021] Please refer to Figure 2 And Figure 3 The utility model is a flat -push window linkage, is installed as Figure 1The flat sliding window 9 comprises a window frame 901 and a window sash 902. The linkage hinge comprises two hinges 10 arranged in upper and lower positions. Each hinge 10 comprises two parallel guide rails 11, and a cross link 12 is arranged between the two guide rails 11. The two guide rails 11 of the two hinges are respectively arranged on the inner wall of the window frame 901 and the outer wall of the window sash 902. The two fixed hinge ends of the cross link 12 are connected with the two guide rails 11 respectively, and the two movable hinge ends are connected with the sliding blocks 13 on the two guide rails 11 respectively. Each guide rail 11 has a sliding groove 14 for restricting the sliding of the sliding block 13, and the cross section of the sliding groove is a C-shaped structure.

[0022] As shown in Figure 2 and Figure 3 , the cross link 12 comprises a first folding rod 121 and a second folding rod 122 which are connected in a cross shape of "X". The first folding rod 121 and the second folding rod 122 are connected by a rotating shaft 123. Here, the side of the first folding rod 121 and the second folding rod 122 above the rotating shaft 123 is the two movable hinge ends of the cross link 12, and the side of the first folding rod 121 and the second folding rod 122 below the rotating shaft 123 is the two fixed hinge ends of the cross link 12. The two fixed hinge ends of the cross link 12 are connected with the guide rails 11 through the first connecting pieces 15 respectively. The two movable hinge ends of the cross link 12 are connected with the two sliding blocks 13 through the second connecting pieces 16 respectively. The first connecting pieces 15 and the second connecting pieces 16 can be common connecting pieces such as screws, pins, rivets, etc.

[0023] In combination with Figure 4 , Figure 5 and Figure 6As shown, the window hinge further comprises a synchronous link assembly 20, a plurality of partition sleeves 21 and a plurality of locking screws. The synchronous link assembly 20 is connected to the movable hinge end of the two hinges 10 on the same side. The synchronous link assembly comprises a first link 201, a second link 202 and a third link 203 connected in sequence from top to bottom. The first link 201 is provided with a vertical avoiding slot 2011 to avoid the same side first connecting piece 15, so that the first link 15 of the synchronous link assembly 20 will not interfere with the same side first connecting piece 15 when moving. The partition sleeve 21 is divided into an upper plate 214 and a lower plate 215, and has a vertical slot 211 inside for the second link to pass through. The upper plate 214 is provided with a through hole 212, and the upper plate 214 is provided with a countersunk hole 213 communicating with the through hole 212. The through hole 212 and the countersunk hole 213 are coaxially arranged. The second link 202 is provided with a through hole 2021 corresponding to the position of the countersunk hole 213. When assembled, the locking screw passes through the through hole 212, the through hole 2021 and the countersunk hole 213 in sequence to fix the partition sleeve on the inner wall of the window frame, wherein the screw head of the locking screw is sunk into the countersunk hole of the lower plate 215 and does not protrude from the countersunk hole to ensure that it does not interfere with the up and down sliding of the second link. The outer surface of the second link 202 is provided with a groove 2022 on both sides. In this embodiment, the material of the synchronous link assembly 20 is aluminum. In this way, compared with the prior art, only one through hole is provided on the second link, and a long strip-shaped stroke waist slot does not need to be provided, and the overall structural strength of the second link will not be reduced.

[0024] In actual use, since the hinges 10 are of the same specification, they can be pre-allocated according to the installation size on site, and only the length of the second link needs to be cut accordingly. During installation, the two guide rails 11 of the two hinges are installed on the inner wall of the window frame 901 and the outer wall of the window sash 902 respectively. Then, the tip of the locking screw passes through the through hole 212, the through hole 2021 and the countersunk hole 213 in sequence to lock the partition sleeve on the inner wall of the window frame 901, and the screw head of the locking screw is sunk into the countersunk hole 213. When the upper hinge 10 is stretched and contracted, the slider 13 of the upper hinge slides up and down along the corresponding guide rail 11, which can drive the synchronous link assembly 20 and the slider 13 of the lower hinge 10 to move synchronously, thereby realizing the synchronous movement of the upper and lower hinges.

[0025] In summary, the utility model discloses a through -going hole and counter -sunk hole are opened respectively on the side wall of the vertical groove front, back two sides of the partition cover, and the tip of locking screw is fixed in the upper window frame in order through the through -going hole, via hole and counter -sunk hole when assembling, and the screw head of locking screw is whole and sinks into the counter -sunk hole, ensure that will not hinder the up-down sliding of second connecting rod, thereby avoid the problem that the second connecting rod whole structural strength declines in the prior art because of setting the travel waist groove on the connecting rod, thereby improve the durability and reliability of second connecting rod.

[0026] The above has carried out the detailed explanation to one embodiment of the utility model, but the content described is only the preferred embodiment of the utility model, can not be considered for limiting the implementation scope of the utility model. All equivalent changes and improvements etc. that are made in the application scope of the utility model should still belong to the patent coverage scope of the utility model.
