The first turnover piece 5 penetrates the first hole 405 and is fastened to the first end of the first connecting rod 201. The second end of the first connecting rod 201 is hingedly connected to the fan connecting piece 3. When turning over, the first end of the first connecting rod 201 turns over together with the first turnover piece 5. The first turnover piece 5 performs a small-angle turning action along the Y axis and the Z axis in the first hole 405 and the second hole 406. The small-angle turning can be understood as being greater than 1° and less than 30°. Of course, the small-angle turning can be flexibly adjusted and changed, and the present application is not limited thereto. In addition, the first turnover piece 5 is in clearance fit with the first hole 405 and the second hole 406. During the operation of the casement window, the first turnover piece 5 rotates relative to the first hole 405 and the second hole 406 of the connecting plate 4, so as to realize the unfolding of the connecting rod assembly 2.

[0068] The transom mounting plate 101 is provided with a first sliding groove which extends along the length direction of the transom mounting plate 101. The second turnover piece 11 is in clearance fit with the first sliding groove and can slide in the first sliding groove. The second turnover piece 11 is provided with a second avoiding part 1102 which allows the second turnover piece 11 to turn over. The first end of the second connecting rod 202 is connected to the second turnover piece 11 through the first connecting piece 7. When turning over, the second connecting rod 202, the first connecting piece 7 and the second turnover piece 11 turn over together relative to the transom mounting plate 101 along the Y axis and the Z axis. The second end of the second connecting rod 202 is hingedly connected to the fan connecting piece 3. Further, the first connecting piece 7 of the present embodiment can adopt a rivet which is fastened to the second turnover piece 11 and turns over with the second turnover piece 11 in the first sliding groove. The first end of the second connecting rod 202 is provided with a hole which is rotatably connected to the first connecting piece 7. In addition, a gasket 10 is arranged between the second connecting rod 202 and the transom mounting plate 101, so as to improve the operation of the connecting rod assembly 2 and reduce the resistance during turning over.

[0069] The second end of the second connecting rod 202 is hingedly connected with the first end of the third connecting rod 203, and the second end of the third connecting rod 203 is hingedly connected with the middle section of the fan connecting piece 3. The connecting rod assembly 2 of the embodiment can refer to the existing technology of the casement window hinge.

[0070] Further, the first end of the first connecting rod 201 is provided with a first connecting hole 2011, and the first turnover piece 5 is further provided with a connecting part 503 matched with the first connecting hole 2011, the connecting part 503 is tightly connected with the first connecting hole 2011, and the connecting part 503 is arranged on the side of the rotating part 502 away from the window transom mounting plate 101. In the embodiment, the first connecting hole 2011 is a special-shaped hole, and the connecting part 503 is also specially-shaped. Specifically, the first connecting hole 2011 is approximately circular and is provided with a cut corner, and the connecting part 503 is shaped the same as the first connecting hole 2011, so that the relative rotation between the first turnover piece 5 and the first connecting hole 2011 is further limited, thereby facilitating the fastening effect of the two. The tight connection between the first connecting hole 2011 and the connecting part 503 in the embodiment can be rivet fastening, and of course other fastening or locking connections can also be used, which can be referred to in the existing technology.

[0071] Further, the first turnover piece 5 of the embodiment is approximately pin-shaped, as shown in FIGS. 4-5, and the first turnover piece 5 is sequentially provided with the connecting part 503, the rotating part 502 and the hook part 501 from top to bottom. The first avoiding part 504 of the embodiment is arranged at the rotating part 502 and the hook part 501 and is located on the same side, specifically in the form of a cut corner at the rotating part 502, and is arranged in a downward inclination at the hook part 501. Such a first avoiding part 504 is beneficial to the smooth turnover of the first turnover piece 5, and the first avoiding part 504 at the hook part 501 is used to abut against the stepped surface of the first hole 405 and the second hole 406 to form a turnover limiting position. The part of the first avoiding part 504 on the rotating part 502 is an unnecessary structure.

[0072] Further, the connecting piece 4 is provided with a protruding part 404 protruding away from the window transom mounting plate 101, and the first hole 405 and the second hole 406 are arranged at the protruding part 404. Through the arrangement of the protruding part 404, on the one hand, the first turnover piece 5 has a certain turnover gap, and through cooperation with the hook part 501, the first turnover piece 5 can be further limited to be pulled out, and on the other hand, the load-bearing capacity of the connecting rod assembly 2 can be improved.

[0073] Further, the connecting plate 4 of the embodiment is provided with a clearance pit 1017 on the surface that is attached to the horizontal frame mounting plate 101; the clearance pit 1017 corresponds to the hook portion 501; the clearance pit 1017 is obliquely arranged to form a turnover space for the turnover movement of the hook portion 501. In this way, when the first turnover piece 5 is turned over, the clearance pit 1017 can make the turnover movement of the hook portion 501 of the first turnover piece 5 more smooth. Specifically, the range of the space of the clearance pit 1017 can be arranged to be greater than the movement range of the hook portion 501, so that the resistance during the turnover movement can be reduced, and the user experience is better.

[0074] The hinge of the embodiment also has a left-right adjusting function. In order to better combine the left-right adjusting function with the turnover function of the sash, the connecting plate 4 is used as part of the left-right adjusting assembly in the embodiment, and the left-right adjusting assembly further includes a first adjusting piece 6. The connecting plate 4 is provided with a first driving hole 402, which is an oblong hole, as shown in FIGS. 4-5. The horizontal frame mounting plate 101 is provided with a second connecting hole 1016; the first adjusting piece 6 is arranged in the first driving hole 402 and the second connecting hole 1016, and the first adjusting piece 6 is eccentrically matched with the first driving hole 402. The horizontal frame mounting plate 101 is provided with a first guide hole 1014 that extends along the length direction of the horizontal frame mounting plate 101, and the connecting plate 4 is provided with a third connecting hole 403; the first guide piece 13 is arranged in the third connecting hole 403 and the first guide hole 1014, and the first guide piece 13 is tightly connected with the third connecting hole 403 of the connecting plate 4.

[0075] Compared with the prior art, the connecting plate 4 of the embodiment is located on the upper surface of the horizontal frame mounting plate 101, which simplifies the structure of the horizontal frame mounting plate 101. When the left-right adjusting is performed, the first adjusting piece 6 drives the first guide piece 13 and the first guide hole 1014 to guide the movement, so that the left-right movement, i.e., the movement along the X axis, is performed, and the connecting rod assembly 2 is moved to achieve the left-right adjusting effect.

[0076] In addition, the connecting plate 4 of the embodiment is further provided with an auxiliary guide assembly between the connecting plate 4 and the horizontal frame mounting plate 101; the auxiliary guide assembly includes a first guide column 401 and a second guide hole 1015, the second guide hole 1015 extends along the length direction of the horizontal frame mounting plate 101, and the first guide column 401 is matched and inserted into the second guide hole 1015. The first guide column 401 is arranged on the connecting plate 4, and the second guide hole 1015 is arranged on the horizontal frame mounting plate 101.

[0077] The auxiliary guide assembly of the embodiment is a preferred design, which can guide the movement of the connecting piece 4 along the X axis and limit the deviation in other directions under the cooperation of the first guide hole 1014 and the first guide piece 13. Meanwhile, the auxiliary guide assembly is also preferably arranged in the embodiment to further limit the movement direction of the connecting piece 4, which is beneficial to improve the left-right adjustment accuracy and stability of the connecting piece 4 and the linkage assembly 2 and prevent the movement towards the Y axis during the left-right adjustment. In addition, the auxiliary guide assembly of the embodiment is located on one side of the X axis center line of the connecting piece 4, while the first guide hole 1014 and the first guide piece 13 are located on the other side, which is beneficial to make the guide limitation more balanced and reliable. Meanwhile, in order to have fewer holes on the connecting piece 4 and make the appearance more beautiful, the first guide column 401 is arranged on the side of the connecting piece 4 abutting the horizontal frame mounting plate 101 and extends downward, while the second guide hole 1015 is arranged on the horizontal frame mounting plate 101. Of course, the first guide column 401 can also be arranged on the horizontal frame mounting plate 101, and the second guide hole 1015 can be arranged on the connecting piece 4.

[0078] The second turnover piece 11 of the embodiment is provided with a protruding limiting portion 1101 on one side in the length direction of the horizontal frame mounting plate 101 and an inwardly inclined slope on the other side, which constitutes the second avoiding portion 1102, and the upper part of the second avoiding portion 1102 is vertically arranged. As shown in FIGS. 10-11, in the non-turnover state, the vertical surface above the second avoiding portion 1102 cooperates with the first sliding groove 1011 on the horizontal frame mounting plate 101, so that the first end of the second linkage 202 can slide along the second sliding groove, thereby realizing the expansion or contraction of the linkage assembly 2 and completing the casement opening or closing. When it is necessary to control the turnover of the casement to form a lower-hung open state, the second avoiding portion 1102 formed by the slope has a certain gap with the first sliding groove, and the second turnover piece 11 is turned to a certain angle in the Y axis direction and the Z axis direction; meanwhile, the limiting portion 1101 on the other side can abut against the window frame profile, so as to improve the reliability after turnover and limit the turnover angle.

[0079] The sealing adjusting assembly of the embodiment comprises a second adjusting member 9. One end of the cross frame mounting plate 101 at the assembly part 1022 is an adjusting end. The cross frame mounting plate 101 is provided with a second driving hole 1013 at the adjusting end. The assembly part 1022 is provided with a fourth connecting hole 10222. A rotatable second adjusting member 9 is arranged in the second driving hole 1013 and the fourth connecting hole 10222. The second adjusting member 9 is eccentrically matched with the second driving hole 1013. The locking end of the cross frame mounting plate 101 is locked on the cross frame of the window frame profile through a locking structure. The axis of the locking structure is a swing axis. The swing axis is parallel to the flat opening rotation axis 14 of the sash. In the locking state of the locking structure, rotating the second adjusting member 9 can promote the cross frame mounting plate 101 to swing around the swing axis.

[0080] In the embodiment, the second adjusting member 9 is arranged at the adjusting end of the cross frame mounting plate 101 and is arranged separately from the connecting rod assembly 2. The second adjusting member 9 is not affected by the operation of the connecting rod assembly 2. The stability of the sealing adjusting amount of the sash can be effectively improved. The second adjusting member 9 is not easy to loosen or wear. Moreover, the other end of the cross frame mounting plate 101 is a locking end. The swing amount adjustment of the cross frame mounting plate 101 and the connecting rod assembly 2 can be completed by separately adjusting the second adjusting member 9 during adjustment. The operation is simple and convenient. Meanwhile, the second adjusting member 9 and the cross frame mounting plate 101 are eccentrically matched. The structure is simple. The hand feeling is smooth and convenient during control.

[0081] The operation surface of the second adjusting member 9 facing the outside (the upper surface in this embodiment) is provided with a counterbore, for example, a hexagonal hole, so that the adjusting member can be rotated by a hexagonal screwdriver to achieve the swing adjustment of the horizontal frame mounting plate 101. Preferably, the second driving hole 1013 in this embodiment is in the shape of an oblong and extends along the X-axis direction. Specifically, the second adjusting member 9 in this embodiment can be divided into an adjusting section, an eccentric section, a connecting section, and a riveting section from top to bottom. The eccentric section is eccentrically matched with the second driving hole 1013, the connecting section is coaxially matched with the fourth connecting hole 10222, the riveting section is formed after the riveting of the fourth connecting hole 10222, and the adjusting section is located on the surface of the horizontal frame mounting plate 101. By matching the eccentric section with the oblong second driving hole 1013, the second adjusting member 9 can be rotated to push the adjusting end of the horizontal frame mounting plate 101 to swing a small angle around the swing axis, so that the position of the connecting rod assembly 2 is also swung synchronously when the horizontal frame mounting plate 101 swings, thereby adjusting the position of the sash to achieve the sealing adjustment of the sash. As for the riveting of the second adjusting member 9 and the fourth connecting hole 10222, it is a controlled torque riveting. After riveting, the second adjusting member 9 cannot move along the Z-axis direction, but can be rotated after overcoming a certain torque, for example, by using a tool to screw it. The controlled torque riveting has the advantage of preventing the position of the second adjusting member 9 from changing during work.

[0082] To improve the accuracy of sealing adjustment, a swing guide structure is provided between the adjusting end of the horizontal frame mounting plate 101 and the assembly part 1022. The swing guide structure includes a second guide column 1018 and a third guide hole 10221, the second guide column 1018 is matched and inserted in the third guide hole 10221, and the third guide hole 10221 is matched with the swing path of the adjusting end of the horizontal frame mounting plate 101 or extends along the width direction of the horizontal frame mounting plate 101. The second guide column 1018 is arranged on the assembly part 1022, and the third guide hole 10221 is arranged on the horizontal frame mounting plate 101. Of course, the second guide column 1018 can also be arranged on the horizontal frame mounting plate 101, and the third guide hole 10221 can be arranged on the assembly part 1022.

[0083] In order to enable the horizontal frame mounting plate 101 to swing more stably and accurately, and to avoid deviation in other directions during adjustment, the swing guide structure can effectively limit the swing direction of the adjusting end of the horizontal frame mounting plate 101, especially the movement of the horizontal frame mounting plate 101 in the Y-axis direction. When adjusting the swing direction of the horizontal frame mounting plate 101, more belongs to small angle swing, therefore, in addition to being provided in the shape of an arc to match the swing path, the third guide hole 10221 can also extend along the Y-axis direction, and the small gap between the structural members can also achieve guiding and limiting.

[0084] The locking end of the horizontal frame mounting plate 101 is locked and fixed by a locking structure, which comprises a clamping piece 12 and a clamping shaft 8. The clamping piece 12 is located below the locking end of the horizontal frame mounting plate 101. The locking end of the horizontal frame mounting plate 101 is provided with a groove 1012, and the groove 1012 is provided with a through hole 10121. The clamping shaft 8 passes through the through hole 10121 and is connected with the clamping piece 12 and can rotate synchronously.

[0085] Specifically, the groove 1012 can accommodate the head of the clamping shaft 8, avoiding protruding from the horizontal frame mounting plate 101. In addition, the clamping shaft 8 cooperates with the clamping piece 12, and a hexagonal hole can be arranged on the clamping piece 12. The clamping shaft 8 and the hexagonal hole are arranged as a hexagonal prism structure, which can realize synchronous rotation of the two and facilitate the clamping shaft 8 to be inserted into the clamping piece 12, and the connection is realized by riveting. The structure of the clamping piece 12 of the embodiment can refer to the prior art, and the clamping piece 12 is rotated to be tightly or loosely arranged in the groove of the horizontal frame, so as to realize locking and disassembly.

[0086] As another embodiment, the locking structure can also adopt other forms, for example, a screw can be used as a locking structure to lock the locking end of the horizontal frame mounting plate 101, which can also realize the locking and fixing effect. At this time, the axis of the screw is the swing axis, and when adjusting the seal, the screw needs to be appropriately loosened, for example, it can be in a half-locking state, so that the horizontal frame mounting plate 101 can swing. After the swing adjustment of the horizontal frame mounting plate 101 is completed to realize the sash seal adjustment, the screw is tightened again. Although the screw is used as the locking structure to realize the swing of the horizontal frame mounting plate 101, the screw needs to be adjusted and matched synchronously during operation, and the operation is not convenient. Therefore, the locking mode of the clamping piece 12 and the clamping shaft 8 is preferred.

[0087] Embodiment 2
