When turning, the first connecting rod 301 performs turning movement relative to the first turnover piece 6. In the embodiment, the first connecting hole 3011 and the first turnover piece 6 are in clearance fit, so that the first end of the first connecting rod 301 can rotate relative to the first turnover piece 6, and can turn at a small angle in the Y-axis and Z-axis directions. The small angle turning can be understood as greater than 1° and less than 30°, and of course the small angle turning can be flexibly adjusted and changed, and the application is not limited to this. The second end of the first connecting rod 301 is connected to the flat opening rotating shaft line 10 of the sash connecting piece 2. In addition, the connecting piece 5 is arranged on the upper surface of the transom mounting plate 101, and is fastened to the first turnover piece 6 to fix the first turnover piece 6, so that the structure is simple, the installation and maintenance are convenient, and the structure of the transom mounting plate 101 can be simplified.

[0050] The transom mounting plate 101 is provided with a first sliding groove 1013 extending along the X-axis direction; the second turnover piece 9 is in clearance fit with the first sliding groove 1013 and can slide in the first sliding groove 1013, and the second turnover piece 9 is provided with a second avoiding part 902; the first end of the second connecting rod 302 is connected to the second turnover piece 9 through a first connecting piece 12; when turning, the second connecting rod 302, the first connecting piece 12 and the second turnover piece 9 together turn relative to the frame mounting piece 1 in the Y-axis and Z-axis directions.

[0051] The second end of the second connecting rod 302 is hingedly connected to the first end of the third connecting rod 303, and the second end of the third connecting rod 303 is hingedly connected to the middle section of the sash connecting piece 2. The hinge rod piece group 3 of the embodiment can refer to the flat opening window hinge in the prior art.

[0052] Further, the first connecting hole 3011 of the embodiment adopts a counterbore, including a first hole section 30111 and a second hole section 30112. The diameter of the first hole section 30111 is larger than that of the second hole section 30112, and the second hole section 30112 penetrates the first connecting rod 301. The first turnover piece 6 can adopt a pin structure or a similar pin structure with a certain axial length. The first turnover piece 6 of the embodiment is provided with a first rotating part 601 and a second rotating part 602. The first rotating part 601 is matched with the first hole section 30111, and the second rotating part 602 is matched with the second hole section 30112. The first avoiding part 6011 is arranged at the first rotating part 601. In order to better enable the first end of the first connecting rod 301 to be turned relative to the first turnover piece 6, the first avoiding part 6011 of the embodiment is a partial corner cut of the bottom surface of the first rotating part 601. For details, please refer to FIG. 5 and FIG. 13.

[0053] 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 sheet 5 of the embodiment is taken as a part of the left-right adjusting assembly, and the left-right adjusting assembly further includes a first adjusting piece 4. Specifically, the horizontal frame mounting plate 101 is provided with a second connecting hole 1015, and the connecting sheet 5 is provided with a first guide hole 501. The first adjusting piece 4 is arranged in the first guide hole 501 and the second connecting hole 1015, and the first adjusting piece 4 is eccentrically matched with the first guide hole 501. The first adjusting piece 4 can be connected with the second connecting hole 1015 by riveting, and the first adjusting piece 4 has a rotatable function. Preferably, the first guide hole 501 of the embodiment is set as a circular hole, so that the first adjusting piece 4 can better form a match therewith and drive the connecting sheet 5 to swing and move along the X axis, thereby realizing left-right adjustment of the hinge rod group.

[0054] Further, the horizontal frame mounting plate 101 is provided with a first guide hole 1014 extending along the X axis direction, and the connecting sheet 5 is provided with a first through hole 502. The first turnover piece 6 is arranged in the first connecting hole 3011, the first through hole 502, and the first guide hole 1014 in sequence, and the first turnover piece 6 can slide in the first guide hole 1014 under the driving of the connecting sheet 5.

[0055] Compared with the prior art, the connecting piece 5 of the embodiment is located on the upper surface of the horizontal frame mounting plate 101, and no guide structure or other limiting structure is required at the connection between the horizontal frame mounting plate 101 and the connecting piece 5, that is, the corresponding positions of the horizontal frame mounting plate 101 and the connecting piece 5 can be smoothly arranged, and the effect of simplifying the structure is particularly obvious. Under this condition, when the left-right adjustment is performed, the connecting piece 5 will swing due to the eccentric cooperation with the first adjusting piece 4, and then move left and right, that is, move along the X axis, and drive the hinge rod assembly 3 to move, so as to realize the left-right adjustment effect, in combination with the guiding effect of the first overturning piece 6 and the first guide hole 1014.

[0056] In addition, the first perforation 502 of the embodiment is provided as a special-shaped hole. The first overturning piece 6 is provided with a connecting portion 603 matched with the first perforation 502. Specifically, the first perforation 502 of the embodiment is provided with a missing corner on the basis of a round hole, so that when the connecting portion 603 of the first overturning piece 6 is matched, the first overturning piece 6 can be effectively limited from rotating. Of course, the first perforation 502 can also be provided as other shaped holes, for example, an internal hexagonal hole, and correspondingly, the connecting portion 603 of the first perforation 502 is matched and provided as a corresponding shape, which can further improve the fastening effect between the first overturning piece 6 and the connecting piece 5. The first perforation 502 and the first overturning piece 6 are fastened and connected, which can be more conveniently matched with the left-right adjustment assembly, and the original structure on the connecting piece 5 is utilized, the design is ingenious, the hinge capable of being flatly opened and overturned and left-right adjusted is formed, and the structure of the left-right adjustment assembly is simple.

[0057] As another embodiment, when the hinge does not need the left-right adjustment function, the first overturning piece 6 and the horizontal frame mounting plate 101 of the embodiment can be fastened and connected, which can realize the fixation of the first overturning piece 6 and the overturning effect of the first connecting rod 301 relative to the first overturning piece 6. Such a structure does not need to additionally assemble parts, and the structure is also simple and reliable.

[0058] The first overturning piece 6 is provided with a hook portion 605, and the hook portion 605 is larger than the first guide hole 1014. Through the arrangement of the hook portion 605, on the one hand, the first overturning piece 6 can be prevented from being pulled out of the first guide hole 1014, and on the other hand, the hook portion 605 can enhance the bearing capacity of the hinge rod assembly 3, especially in the window sash overturning state, the bearing capacity and safety can be obviously improved. The hook portion 605 of the embodiment can be formed in a riveting process. The embodiment is further provided with a check ring 14 between the hook portion 605 and the frame mounting piece 1.

[0059] Further, the first turnover piece 6 of the embodiment is sequentially provided with a first rotating part 601, a second rotating part 602, a connecting part 603, a guiding part 604 and a hook part 605 from top to bottom in the Z-axis direction. The guiding part 604 can directly adopt a cylindrical structure, which is convenient for cooperation with the first guiding hole 1014, so that the movement of the first turnover piece 6 in the X-axis direction is facilitated when the left-right adjustment is performed, thereby driving the left-right adjustment of the hinge rod piece group 3.

[0060] When the left-right direction (i.e. the X-axis direction in the figure) adjustment of the hinge rod piece group 3 is needed, the first adjusting piece 4 is rotated, the eccentric cooperation between the first adjusting piece 4 and the first guiding hole 501 on the connecting sheet 5 is utilized, the connecting sheet 5 is pulled to swing and move left and right, thereby driving the left-right movement of the first turnover piece 6 and the hinge rod piece group 3 as a whole. At the same time, the movement direction of the first turnover piece 6 can be limited by the first guiding hole 1014, which further improves the accuracy and reliability of the left-right adjustment, avoids the shift of the hinge rod piece group 3 in other directions when the left-right adjustment is performed, and especially avoids the shift of the horizontal frame mounting plate 101 in the Y-axis direction. In addition, the connecting sheet 5 of the embodiment adopts a flat plate shape, which can be formed by stamping processing, and has the advantage of low cost. At the same time, the connecting sheet 5 of the embodiment is not provided with a long circular hole structure, and the first guiding hole 501 and the first through hole 502 are both circular hole structures, which is conducive to reducing the overall shaking of the product, and is also convenient for cooperation with the first turnover piece 6 and the first connecting rod 301, thereby forming a hinge with left-right adjustment function and turning function. In addition, since the first guiding hole 501 on the connecting sheet 5 of the embodiment adopts a circular hole structure, it can be completely covered by the head of the first adjusting piece 4, thereby avoiding the entry of dust and sundries, and improving the reliability and surface appearance.

[0061] In the embodiment, the second turning member 9 is provided with a raised limiting part 901 on one side of the length direction of the transom mounting plate 101 and an inwardly inclined slope on the other side, which forms the second avoiding part 902, and the upper part of the second avoiding part 902 is vertically arranged. As shown in FIG. 10 and FIG. 11, in the non-turning state, the vertical surface above the second avoiding part 902 cooperates with the first sliding groove 1013 on the transom mounting plate 101, so that the first end of the second connecting rod 302 can slide along the second sliding groove, thereby realizing the expansion or contraction of the hinge rod assembly 3 and completing the opening or closing of the sash. When it is necessary to control the turning of the sash to form a lower-hung open state, the second avoiding part 902 formed by the slope has a certain gap with the first sliding groove 1013, and the second turning member 9 is turned by a certain angle in the Y-axis direction and the Z-axis direction; at the same time, the limiting part 901 on the other side can abut against the window frame profile to improve the reliability after turning and limit the turning angle. In addition, the first connecting member 12 of the embodiment is fastened to the second turning member 9 by riveting, and the first end of the second connecting rod 302 is provided with a through hole to rotatably connect with the first connecting member 12. A gasket 13 is further arranged between the first end of the second connecting rod 302 and the transom mounting plate 101 to improve the operation of the hinge rod assembly 3 and reduce the resistance during turning.

[0062] The sealing adjusting assembly of the embodiment includes a second adjusting member 8. One end of the transom mounting plate 101 at the assembly part 1022 is an adjusting end, the transom mounting plate 101 is provided with a second guide hole 1016 at the adjusting end, the assembly part 1022 of the vertical frame mounting plate 102 is provided with a third connecting hole 10221, the second adjusting member 8 is arranged in the second guide hole 1016 and the third connecting hole 10221 and can rotate, and the second adjusting member 8 is eccentrically matched with the second guide hole 1016. The locking end of the transom mounting plate 101 is locked on the transom of the window frame through a locking structure, the axis of the locking structure is a swing axis 11, the swing axis 11 is parallel to the horizontal opening rotation axis 10 of the sash; in the locking state of the locking structure, rotating the second adjusting member 8 can cause the transom mounting plate 101 to swing around the swing axis 11.

[0063] The second adjusting member 8 is arranged at the adjusting end of the transom mounting plate 101 and is arranged separately from the hinge rod set 3. The second adjusting member 8 is not affected by the operation of the hinge rod set 3, and the stability of the sealing adjustment amount of the sash can be effectively improved, so that the second adjusting member 8 is not prone to loosening or wear. Moreover, the other end of the transom mounting plate 101 is a locking end, that is, the swing amount adjustment of the transom mounting plate 101 and the hinge rod set 3 can be completed by separately adjusting the second adjusting member 8 during adjustment, which is simple and convenient to operate. At the same time, the second adjusting member 8 and the transom mounting plate 101 are matched in an eccentric manner, which is simple in structure, smooth in hand feeling during control, and convenient.

[0064] The operation surface of the second adjusting member 8 is provided with a counterbore, for example, a hexagonal hole, and the adjusting member can be rotated by a hexagonal screwdriver to realize the swing adjustment of the transom mounting plate 101. Preferably, the second guide hole 1016 is arranged in an elongated circular shape and extends along the X-axis direction. Specifically, the second adjusting member 8 of the 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 matched with the second guide hole 1016 in an eccentric manner, the connecting section is coaxially matched with the third connecting hole 10221, the riveting section is a part formed after the riveting of the third connecting hole 10221, and the adjusting section is located on the surface of the transom mounting plate 101. The eccentric section is matched with the second guide hole 1016 in an eccentric manner to push the adjusting end of the transom mounting plate 101 to swing a small angle around the swing axis 11 when the second adjusting member 8 rotates, so that the position of the hinge rod set 3 is also swung when the transom mounting plate 101 swings, thereby being able to adjust the position of the sash to realize the sealing adjustment of the sash. As for the riveting of the second adjusting member 8 and the third connecting hole 10221, it is a controlled torque riveting. After riveting, the second adjusting member 8 cannot move along the Z-axis direction, but can rotate after overcoming a certain torque, for example, can be screwed by a tool. The controlled torque riveting has the advantage of preventing the position of the second adjusting member 8 from changing.

[0065] In order to improve the accuracy during sealing adjustment, the swing guide structure is arranged between the adjusting end of the transom mounting plate 101 and the assembly part 1022. The swing guide structure includes a guide column 1017 and a second guide hole 10222. The guide column 1017 is matched and inserted into the second guide hole 10222.
