The connecting piece 4 is provided with a first hole 405 and a second hole 406 arranged coaxially, the first hole 405 is located on the side of the second hole 406 away from the window frame profile and passes through the surface of the connecting piece 4, and the inner diameter of the second hole 406 is larger than that of the first hole 405; the first flip member 5 is provided with a rotating part 502 and a hook part 501 that match the first hole 405 and the second hole 406 respectively and have clearance fit, and the hook part 501 is provided with a first avoidance part 504 that allows the first flip member 5 to flip relative to the connecting piece 4; the first flip member 5 passes through 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 hinged to the fan connecting member 3. When flipping, the first end of the first connecting rod 201 flips together with the first flip member 5, and the first flip member 5 performs a small-angle flipping action along the Y axis and the Z axis in the first hole 405 and the second hole 406. The small-angle flipping can be understood as being greater than 1° and less than 30°. Of course, the small-angle flipping can be flexibly adjusted and changed, and the utility model is not limited thereto. In addition, the first flip member 5 is clearance-fitted with the first hole 405 and the second hole 406. When the casement action is performed, the first flip member 5 rotates relative to the first hole 405 and the second hole 406 of the connecting piece 4 to achieve the expansion of the connecting rod assembly 2.

[0062] The transverse frame mounting plate 101 is provided with a first slide groove, which extends along the length direction of the transverse frame mounting plate 101; the second flipping member 11 is loosely matched with the first slide groove and can slide in the first slide groove, and the second flipping member 11 is provided with a second avoidance portion 1102 that allows the second flipping member 11 to flip; the first end of the second connecting rod 202 is connected to the second flipping member 11 through the first connecting member 7; when flipping, the second connecting rod 202, the first connecting member 7 and the second flipping member 11 flip along the Y axis and the Z axis relative to the transverse frame mounting plate 101; the second end of the second connecting rod 202 is hinged to the fan connecting member 3. Furthermore, the first connecting member 7 of this embodiment can be a rivet, which is fastened to the second flipping member 11 and flips in the first slide groove with the second flipping member 11. The first end of the second connecting rod 202 is provided with a hole, which is rotatably connected to the first connecting member 7. In addition, a gasket 10 is provided between the second connecting rod 202 and the cross frame mounting plate 101 to improve the smooth operation of the connecting rod assembly 2 and reduce resistance during flipping.

[0063] The second end of the second connecting rod 202 of this embodiment is hinged to the first end of the third connecting rod 203, and the second end of the third connecting rod 203 is hinged to the middle section of the sash connector 3. The connecting rod assembly 2 of this embodiment can refer to the casement window hinge in the prior art.

[0064] Further, in this embodiment, a first connecting hole 2011 is provided at the first end of the first connecting rod 201; a connecting portion 503 cooperating with the first connecting hole 2011 is also provided on the first flip member 5, and the connecting portion 503 is fastened to the first connecting hole 2011; the connecting portion 503 is arranged on the side of the rotating portion 502 away from the transverse frame mounting plate 101. In this embodiment, the first connecting hole 2011 is a special-shaped hole, and the connecting portion 503 is matched and arranged to be a special-shaped hole; specifically, the first connecting hole 2011 is roughly circular and has a cut corner, and the shape of the connecting portion 503 is consistent with the first connecting hole 2011, which can further limit the relative rotation between the first flip member 5 and the first connecting hole 2011, thereby facilitating the improvement of the fastening effect of the two. In this embodiment, the fastening connection between the first connecting hole 2011 and the connecting portion 503 can be fastened by riveting, and of course, other fastening or locking methods can also be adopted, and the details can be referred to the prior art.

[0065] Furthermore, the structure of the first flip member 5 of this embodiment is roughly pin-shaped, see Figure 4-Figure 5 , the first flip member 5 is composed of a connecting portion 503, a rotating portion 502 and a hook portion 501 from top to bottom. The first avoidance portion 504 of this embodiment is provided at both the rotating portion 502 and the hook portion 501, and is located on the same side. The rotating portion 502 is specifically a cut-off structure, and the first avoidance portion 504 at the hook portion 501 is tilted downward. Such a first avoidance portion 504 is conducive to a smoother flipping action of the first flip member 5, and the first avoidance portion 504 located at the hook portion 501 can be used to abut against the step surface of the first hole 405 and the second hole 406 to form a flip limit. However, part of the first avoidance portion 504 on the rotating portion 502 in this embodiment is an unnecessary structure.

[0066] Furthermore, the connecting piece 4 is provided with a protrusion 404, and the protrusion 404 protrudes toward a side away from the window transverse frame mounting plate 101; the first hole 405 and the second hole 406 are provided at the protrusion 404. The provision of the protrusion 404 can, on the one hand, allow the first flip member 5 to have a certain flipping clearance, and, by cooperating with the hook portion 501, can further limit the first flip member 5 from coming out; on the other hand, can improve the load-bearing capacity of the connecting rod assembly 2.

[0067] Furthermore, in this embodiment, the mating surface of the transverse frame mounting plate 101 and the connecting piece 4 is provided with a clearance pit 1017; the clearance pit 1017 corresponds to the hook part 501; the clearance pit 1017 is tilted to form a flipping space for the hook part 501 to perform flipping movement. In this way, when the first flip member 5 flips, the clearance pit 1017 can make the flipping movement of the hook part 501 of the first flip member 5 smoother. Specifically, the range of the space of the clearance pit 1017 can be set to be larger than the movement range of the hook part 501, so that the resistance during the flipping movement can be reduced, allowing a better user experience.

[0068] The hinge of this embodiment also has a left-right adjustment function. In order to better combine the left-right adjustment function with the flipping function of the window sash, this embodiment uses the connecting piece 4 as a part of the left-right adjustment component, and the left-right adjustment component also includes a first adjustment member 6. The connecting piece 4 is provided with a first driving hole 402, which is an oblong hole. Figure 4-Figure 5 The transverse frame mounting plate 101 is provided with a second connection hole 1016; the first adjustment member 6 is inserted into the first drive hole 402 and the second connection hole 1016, and the first adjustment member 6 is eccentrically matched with the first drive hole 402. The transverse frame mounting plate 101 is provided with a first guide hole 1014, and the first guide hole 1014 extends along the length direction of the transverse frame mounting plate 101. The connecting piece 4 is provided with a third connection hole 403; the third connection hole 403 and the first guide hole 1014 are penetrated by a first guide member 13, and the first guide member 13 is fastened to the third connection hole 403 of the connecting piece 4.

[0069] Compared with the prior art, the connecting piece 4 of this embodiment is located on the upper surface of the transverse frame mounting plate 101, which simplifies the structure of the transverse frame mounting plate 101. When adjusting left and right, driven by the first adjusting member 6, combined with the guiding function of the first guide member 13 and the first guide hole 1014, it will move left and right, that is, move along the X-axis, and drive the connecting rod assembly 2 to move, so as to achieve the effect of left and right adjustment.

[0070] In addition, an auxiliary guide assembly is further provided between the connecting piece 4 and the transverse frame mounting plate 101 of this embodiment; 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 transverse 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 provided on the connecting piece 4, and the second guide hole 1015 is provided on the transverse frame mounting plate 101.

[0071] The auxiliary guide assembly of this embodiment is a preferred design. With the cooperation of the first guide hole 1014 and the first guide member 13, the connecting piece 4 can be guided to move along the X axis and the deviation in other directions can be limited. At the same time, the auxiliary guide assembly is preferably set in this embodiment to further limit the moving direction of the connecting piece 4, which is conducive to improving the left-right adjustment accuracy and stability of the connecting piece 4 and the connecting rod assembly 2, and preventing movement to the Y axis when the left-right adjustment is performed. In addition, the auxiliary guide assembly of this embodiment is located on one side of the center line of the X axis of the connecting piece 4, while the first guide hole 1014 and the first guide member 13 are located on the other side, which is conducive to making the guiding restriction more balanced and reliable. At the same time, in order to make the holes on the connecting piece 4 less and the appearance more beautiful, the first guide column 401 is set on the side of the connecting piece 4 that is attached to the horizontal frame mounting plate 101 and extends downward, and the second guide hole 1015 is set on the horizontal frame mounting plate 101. Of course, the first guide column 401 can also be set on the horizontal frame mounting plate 101, and the second guide hole 1015 is set on the connecting piece 4.

[0072] The second flip member 11 of this embodiment is provided with a raised stopper 1101 on one side of the longitudinal direction of the horizontal frame mounting plate 101, and an inwardly inclined surface is provided on the other side, the inclined surface forming the second avoidance portion 1102, and the upper part of the second avoidance portion 1102 is vertically arranged. Figure 10-11 As shown, in the non-flipping state, the vertical surface above the second avoidance portion 1102 cooperates with the first slide groove 1011 on the horizontal frame mounting plate 101, so that the first end of the second connecting rod 202 can slide along the second slide groove, thereby realizing the expansion or contraction of the connecting rod assembly 2, and completing the horizontal opening or closing of the window sash. When it is necessary to control the window sash to flip and form a downward hanging open state, there is a certain gap between the second avoidance portion 1102 formed by the inclined surface and the first slide groove, and the second flip member 11 is flipped to a certain angle in the Y-axis direction and the Z-axis direction; at the same time, since a limiting portion 1101 is provided on the other side, the limiting portion 1101 can abut against the window frame profile to improve the reliability after flipping and limit the flipping angle.

[0073] The sealing adjustment assembly of this embodiment includes a second adjustment member 9. One end of the transverse frame mounting plate 101 located at the assembly portion 1022 is the adjustment end; the transverse frame mounting plate 101 is provided with a second drive hole 1013 at the adjustment end, and the assembly portion 1022 is provided with a fourth connection hole 10222. A rotatable second adjustment member 9 is inserted through the second drive hole 1013 and the fourth connection hole 10222, and the second adjustment member 9 is eccentrically matched with the second drive hole 1013. The locking end of the transverse frame mounting plate 101 is locked on the transverse frame of the window frame profile by a locking structure, and the axis of the locking structure is a swing axis, and the swing axis is parallel to the horizontal opening rotation axis of the window sash; in the locked state of the locking structure, rotating the second adjustment member 9 can cause the transverse frame mounting plate 101 to swing around the swing axis.

[0074] In this embodiment, the second adjusting member 9 is arranged at the adjustment end of the horizontal frame mounting plate 101 and is separated from the connecting rod assembly 2. The second adjusting member 9 is not affected by the operation of the connecting rod assembly 2, which can effectively improve the stability of the window sash sealing adjustment amount, so that the second adjusting member 9 is not easy to loosen or wear. In addition, the other end of the horizontal frame mounting plate 101 is a locking end, that is, when adjusting, the second adjusting member 9 can be adjusted to complete the swing amount adjustment of the horizontal frame mounting plate 101 and the connecting rod assembly 2, and the operation is simple and convenient. At the same time, the second adjusting member 9 and the horizontal frame mounting plate 101 are eccentrically matched, with a simple structure and a smooth and convenient feel when controlling.

[0075] The side of the second adjusting member 9 facing the outside world (the upper surface in this embodiment) is an operating surface, and a countersunk hole is provided on the operating surface, for example, it can be set as a hexagonal hole, and the adjusting member can be rotated by a hexagonal screwdriver to achieve the swing adjustment of the cross frame mounting plate 101. Preferably, in this embodiment, the second driving hole 1013 is set to an oblong shape, extending along the X-axis direction. Specifically, the second adjusting member 9 of this embodiment can be divided into an adjustment section, an eccentric section, a connecting section and a riveted 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 riveted section is a portion formed after riveting with the fourth connecting hole 10222, and the adjustment section is located on the surface of the cross frame mounting plate 101. The eccentric section cooperates with the oblong second driving hole 1013, so that when the second adjusting member 9 rotates, the adjusting end of the horizontal frame mounting plate 101 is pushed to swing back and forth at a small angle around the swing axis. When the horizontal frame mounting plate 101 swings, the position of the connecting rod assembly 2 is also driven to swing synchronously, so that the position of the window sash can be adjusted to achieve the sealing adjustment of the window sash. The riveting between the second adjusting member 9 and the fourth connecting hole 10222 is a controlled torque riveting. After riveting, the second adjusting member 9 cannot move along the Z axis, but can be rotated after overcoming a certain torque, for example, it can be screwed with a tool; the advantage of this controlled torque riveting is to prevent the position of the second adjusting member 9 from being offset during operation.

[0076] In order to improve the accuracy of sealing adjustment, a swing guide structure is provided between the adjustment end of the transverse frame mounting plate 101 and the assembly portion 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 into the third guide hole 10221. The third guide hole 10221 matches the swing path of the adjustment end of the transverse frame mounting plate 101 or extends along the width direction of the transverse frame mounting plate 101. The second guide column 1018 is provided on the assembly portion 1022, and the third guide hole 10221 is provided on the transverse frame mounting plate 101. Of course, the second guide column 1018 can also be provided on the transverse frame mounting plate 101, and the third guide hole 10221 can be provided on the assembly portion 1022.

[0077] In order to make the horizontal frame mounting plate 101 more stable and accurate in swing adjustment and avoid deviation in other directions during the adjustment process, the present embodiment can effectively limit the swing direction of the adjustment end of the horizontal frame mounting plate 101 through the setting of the swing guide structure, and can especially limit 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, it is more of a small-angle swing, so the third guide hole 10221 can be set to an arc shape to match the swing path, and can also be set to extend along the Y-axis direction, and the small gap between the structural parts can also be used to achieve guidance and limit.

[0078] The present embodiment adopts a locking structure to lock and fix the locking end of the transverse frame mounting plate 101, and the locking structure includes a clamping plate 12 and a clamping shaft 8; the clamping plate 12 is located below the locking end of the transverse frame mounting plate 101, and a groove 1012 is provided at the locking end of the transverse frame mounting plate 101, and a through hole 10121 is provided on the groove 1012. After the clamping shaft 8 passes through the through hole 10121, it is connected to the clamping plate 12 and can rotate synchronously.

[0079] Specifically, the head of the clamping shaft 8 can be accommodated by setting the groove 1012 to avoid protruding from the horizontal frame mounting plate 101. In addition, the clamping shaft 8 and the clamping sheet 12 can be matched by setting a hexagonal hole on the clamping sheet 12, and setting the matching part of the clamping shaft 8 and the hexagonal hole as a hexagonal prism structure, so that the synchronous rotation of the two can be achieved, and it is also convenient for the clamping shaft 8 to be inserted into the clamping sheet 12 and connected by riveting. The structure of the clamping sheet 12 of this embodiment can refer to the prior art, and the locking and disassembly can be achieved by rotating to achieve mutual contact or loosening with the slot on the horizontal frame.

[0080] As another embodiment, the locking structure may also be in other forms, for example, a screw may be used as a locking structure to lock the locking end of the transverse frame mounting plate 101, which can also achieve a locking and fixing effect. At this time, the axis of the screw is the swing axis. When adjusting the seal, it is necessary to loosen the screw appropriately first, for example, it can be in a semi-locked state, so that the transverse frame mounting plate 101 can swing. After completing the swing adjustment of the transverse frame mounting plate 101 to achieve the window sash seal adjustment, retighten the screw. Although the use of screws as a locking structure can also achieve the swing of the transverse frame mounting plate 101, the screws need to be adjusted and matched synchronously during operation, and the operation is not convenient enough. Therefore, it is preferred to use a locking method of the clamping sheet 12 and the clamping shaft 8.

[0081] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Therefore, any modification, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the technical solution of the present invention are still within the scope of the technical solution of the present invention.
