Description

Technical Field

[0001] This invention relates to the field of hinge technology, and more particularly to a hinge for windows. Background Technology

[0002] With the continuous development of urban construction, more and more buildings are using glass curtain walls. Most existing glass curtain walls use aluminum alloy profiles for the window frames and sashes. The window sashes open and close in two ways: casement and outward-opening. Casement window sashes are typically connected by hinges. Existing hinges connecting the frame and sash of doors and windows can support the sash and allow it to rotate and open / close. However, existing hinges are mainly five-bar linkages. Five-bar hinges have poor wind pressure resistance during opening. When the window sash is opened to its maximum instantaneous position, due to the inertia of the sash, the hinge cannot withstand impact forces. Because the first mounting bracket of the traditional five-bar hinge has a groove, and the slider is located in the groove of the slide rail and slides with the groove, the sliding range of the slider on the slide rail cannot be fitted with fixing screws. This reduces the hinge strength and easily leads to problems such as insecure slide rail installation, warping and deformation of the grooved part of the first mounting bracket, causing irreversible damage to the hinge, damaging the window profile itself, rendering the window unusable, and even causing safety accidents. Furthermore, existing hinge structures have grooves on the first mounting base, which, due to long-term sliding friction, and the tendency for debris to fall into these grooves during home renovations and daily use, are difficult to clean. Repeated opening and closing also causes the hinges to wear down significantly, leading to jamming and stopping when opening and closing the window, severely impacting its lifespan and hindering long-term use. In addition, errors in the manufacturing of the hinges themselves and the window profiles result in high precision requirements for the entire window manufacturing process, significantly impacting production efficiency. Therefore, this paper proposes a window hinge that increases the hinge's wind pressure resistance, enhances its safety protection, and prevents excessive wear caused by the grooves, thereby ensuring window stability and reliability. Summary of the Invention

[0003] To address the aforementioned issues, this application proposes a window hinge that resolves the problems of window safety and service life. Windows using this hinge can improve their wind pressure resistance, preventing deformation or interference between the hinge and the frame structure during strong winds, thus enhancing the hinge's safety and preventing excessive wear on the hinge due to the sliding groove, thereby ensuring window stability and reliability.

[0004] This application is achieved through the following technical solution:

[0005] A window hinge includes a first mounting base connected to a window frame, a second mounting base connected to a window sash, and a linkage assembly. The linkage assembly includes a first connecting rod, a second connecting rod, and a third connecting rod. One end of the first connecting rod is hinged to the first mounting base, and the other end of the first connecting rod and one end of the second connecting rod are respectively hinged to the second mounting base. Both ends of the third connecting rod are respectively hinged to the first mounting base and the second connecting rod.

The limiting components are located near the hinge point between the second mounting base and the first connecting rod.

[0009] Furthermore, the limiting component includes a limiting point and a limiting block. The limiting point is disposed on the lower surface of the second mounting base and is columnar. The limiting block is disposed on the upper surface of the first connecting rod and is formed by the upward protrusion of the rod body of the first connecting rod. It is used to limit the opening when the hinge is opened to a preset angle by the limiting block abutting against the limiting point.

[0010] Furthermore, the limiting point and / or the limiting block are integrally formed with the corresponding connected second mounting base or the first connecting rod.

[0011] Furthermore, the second mounting base and the second connecting rod are provided with mutually cooperating limiting components.

The first mounting base has a first strip hole, a second strip hole, and a third strip hole. The ends of the first connecting rod and the third connecting rod are provided with pivots that pass through the second strip hole and the third strip hole, respectively, and are connected to the adjusting plate. A sealing member and a first fixing member are provided at the first strip hole, and the pivots pass through the sealing member, the first strip hole, the adjusting plate, and the first fixing member in sequence.

The first mounting base has a first limiting portion that cooperates with the first engaging portion to limit the movement direction of the sealing member. The first mounting base has a first limiting hole, and the adjusting member passes through the first limiting hole and is connected to the adjusting plate to control the movement of the adjusting plate in the length direction of the first mounting base.

[0016] Furthermore, the adjusting component is an adjusting shaft with an eccentric structure, the first limiting hole is circular or elongated, the adjusting shaft passes through the first limiting hole and connects to the adjusting plate, and the eccentric structure of the adjusting shaft controls the movement of the adjusting plate.

[0017] Furthermore, the adjustment assembly also includes a swing plate and a fixed shaft. The swing plate has a through hole for the fixed shaft to pass through and connect to the adjustment plate. The adjustment plate has a fourth strip hole, and the adjustment component passes through the first limiting hole and the fourth strip hole in sequence to connect to the swing plate.

[0018] Furthermore, the adjusting screw is rotatably positioned in the first limiting hole, and the adjusting plate is provided with a screw hole that mates with the adjusting screw, so that when the adjusting screw rotates, the adjusting plate moves along the length direction of the first mounting base.

[0019] Furthermore, the adjusting component is an adjusting screw, which has a fourth limiting part. The first limiting hole is an elongated through hole with an enlarged part and a third limiting part. The adjusting plate has a second engaging part that cooperates with the first limiting hole. The second engaging part extends upward from the adjusting plate, so that the second engaging part can pass through the first limiting hole, be located above the first mounting base, and be engaged in the third limiting part. Both ends of the second engaging part have grooves or through holes that allow the adjusting screw to be horizontally embedded. The second engaging part has a screw hole for rotating and adjusting the movement of the second engaging part in the length direction of the first limiting hole in cooperation with the adjusting screw.

[0020] Furthermore, the adjusting member includes a protruding member and a recessed member that meshes with the protruding member.

[0022] A window includes a window frame and a window sash, including the aforementioned window hinge, a first mounting base connected to the window frame, and a second mounting base connected to the window sash.

[0023] The beneficial effects of this application are:

[0024] 1. The hinge of this application is a six-link full rotation point structure, and all links are connected by rotation. The structure is simple and the mechanical performance is stable. It can improve the wind pressure resistance and service life at the same time, and solve the problem that the wind pressure resistance and mechanical stability of traditional hinges are reduced due to the presence of grooves.

[0025] 2. The interconnected rods in this application mutually constrain each other's degrees of freedom, ensuring a unique opening and closing trajectory for the hinge, avoiding interference with the profile structure, and ensuring that each rod is indispensable and the mechanical performance is stable.

[0026] 3. After the hinge limit is opened, the second connecting rod and the fourth connecting rod are in a straight line, which makes the load-bearing capacity of the second connecting rod and the fourth connecting rod stronger, and makes the wind pressure resistance of the entire hinge stronger.

[0027] 4. Adding a connecting rod to the full rotation point hinge of the six-bar linkage enhances the force on each part of the hinge. Especially when the hinge is resisting crosswind pressure, the multiple connecting rods assist the six-bar linkage in bearing the force, dispersing the destructive force on the hinge itself, thereby enhancing the safety protection effect of the hinge.

[0028] 5. Adding an adjustable function to the multi-link full rotation point structure hinge enhances the window's sealing performance and reduces the difficulty of door and window manufacturing. Especially under heavy window conditions, the adjustable function of the hinge can compensate for the deformation of the window and hinge, thereby enhancing the safety protection effect of the hinge.

[0029] 6. In this application, the cooperation of limiting blocks and limiting points on the first connecting rod, the second connecting rod, or the second mounting base facilitates limiting the opening and closing angle between the second mounting base and the first mounting base, so that it can unfold or overlap within a preset angle.

[0030] 7. A second fixing hole is provided on the first mounting base, and a rotating shaft is provided to connect the second fixing device to form a clamp for fixing to the target installation object. The clamp and the rotating shaft can rotate synchronously, and a first protrusion and a first recess are provided to cooperate with each other, so as to play a positioning role to limit the rotation angle of the fixing member and prevent the second fixing member from retracting and falling out of the profile groove after the hinge is installed.

[0052] The description of "hinged" in this application includes both forms of direct hinged connection and forms of indirect riveting achieved through a medium attached to one of the two.

[0053] Example 1

[0054] like Figure 1 and Figure 2 As shown in the illustration, an embodiment of this application discloses a window hinge, comprising a first mounting base 1 connected to a window frame, a second mounting base 2 connected to a window sash, and a connecting rod assembly. The connecting rod assembly includes a first connecting rod 3, a second connecting rod 4, and a third connecting rod 5. One end of the first connecting rod 3 is hinged to the first mounting base 1, and the other end of the first connecting rod 3 and one end of the second connecting rod 4 are respectively hinged to the second mounting base 2. Both ends of the third connecting rod 5 are respectively hinged to the first mounting base 1 and the second connecting rod 4. The connecting rod assembly also includes a fourth connecting rod 6; both ends of the fourth connecting rod 6 are respectively hinged to the first mounting base 1 and the second connecting rod 4. In this embodiment, all connection points are rotary connections, forming a structure with all rotary connection points, which strengthens the load-bearing capacity of the entire hinge and increases its safety protection effect.

[0055] In a preferred embodiment, the first mounting base 1 is provided with a first connecting rod mounting hole, and a gasket is provided between the first connecting rod 3 and the first mounting base 1. A first rotating shaft is provided on the mounting hole of the first connecting rod, and the first rotating shaft passes through the first connecting rod 3, the gasket, and the first mounting base 1 in sequence and connects them. The first mounting base 1 has second protrusions at both ends near the mounting hole of the first connecting rod 3, which can cooperate with the target object fixed to the first mounting base 1. When the hinge receives a continuous or instantaneous maximum angle opening impact, it can effectively prevent the first mounting base 1 from bending into a sickle shape, thereby improving the safety and stability of the hinge.

[0056] In a preferred embodiment, a gasket is provided at the connection between the second mounting base 2 and the first connecting rod 3, and the two are connected by a rotating shaft passing through the mounting holes of the second mounting base 2, the gasket, and the first connecting rod 3 in one pass. The second mounting base 2 is provided with a positioning part, which can quickly position the rod through the groove without the need for back-and-forth adjustment. The second mounting base 2 is provided with a threaded hole and equipped with a screw that matches the threaded hole. The screw is threaded onto the second mounting base 2, and tightening the screw fixes the second mounting base 2 in the profile groove, which can quickly position and install the rod, improving installation efficiency.

[0057] In a preferred embodiment, the second mounting base 2 and the first connecting rod 3 are provided with mutually cooperating limiting components to restrict the second mounting base 2 and the first mounting base 1 from unfolding or overlapping within a set angle. The limiting components are located near the hinge point between the second mounting base 2 and the first connecting rod 3. The limiting components include a limiting point 31 and a limiting block 32. The limiting point 31 is located on the lower surface of the second mounting base 2 and is columnar. The limiting block 32 is located on the upper surface of the first connecting rod 3 and is formed by the upward protrusion of the rod body of the first connecting rod 3. When the hinge is opened to a preset angle, the limiting block 32 abuts against the limiting point 31 to achieve limited opening and improve the wind pressure resistance of the hinge.

[0058] In a preferred embodiment, the first mounting base 1 has a first positioning hole 14 and a second positioning hole 15 at both ends. A sealing element 7 and a first fixing element 11 are provided at the first positioning hole. A first fixing shaft passes through the first positioning hole, sequentially passing through the sealing element 7, the first mounting base 1, and the first fixing element 11. The first mounting base 1 has a fixing element limiting point. The first fixing element 11 cooperates with the fixing element limiting point to provide initial positioning. When disassembling the hinge, the first fixing element 11 can be quickly positioned, preventing over-rotation that would prevent disassembly. The sealing element 7 has a positioning part, and the first positioning hole 14 on the first mounting base 1 allows for quick positioning and assembly of the sealing element 7, and also prevents the sealing element 7 from shifting from its initial position during use, which could lead to hinge sealing failure.

[0059] In a preferred embodiment, the second mounting base 4 is provided with a guide head 22 that can cooperate with the seal 7. When the hinge assembly is closed, the guide head 22 cooperates with the seal 7 to achieve a sealing effect. In this embodiment, the guide head 22 is integrally formed with the second mounting base 4. In other embodiments, the guide head 22 may also be formed by an additional plate riveted to the second mounting base 4.

[0060] In a preferred embodiment, the second positioning hole 15 is located on the first mounting base 1 at the end away from the seal 7. A second fixing member 12 and a second fixing shaft are provided at the second positioning hole. The second fixing shaft passes through the second positioning hole to fix the second fixing member 12 to the first mounting base 1. Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, the second fixing member 12 is provided with a first protrusion 121, and the first mounting base 1 is provided with a second recess 122 that cooperates with the first protrusion 121, which plays a positioning role, restricts the rotation angle of the second fixing member 12, and prevents the second fixing member 12 from retracting and falling out of the profile groove after the hinge is installed.

[0061] In a preferred embodiment, a shim is provided at the hinge of the second connecting rod 4 and the fourth connecting rod 6. The rotating shaft passes through the mounting holes on the second connecting rod 4, the shim, and the fourth connecting rod 6 in sequence to connect them. This increases the fourth connecting rod 6 to realize the six-bar full rotation point structure of the hinge, so that the first mounting seat 1 and the second mounting seat 2 can be unfolded or overlapped within a set angle, so that the hinge can be used normally.

[0062] Example 2

[0063] like Figure 7 and Figure 8 As shown, the difference between this embodiment and embodiment 1 is that the limiting component includes a limiting point 31 and a limiting block 32. The limiting point 31 is located on the upper surface of the first connecting rod 3 and is columnar. The limiting block 32 is located on the lower surface of the second mounting base 2 and is a square block. When the hinge is opened to a preset angle, the limiting block 32 abuts against the limiting point 31 to achieve limiting opening and improve the hinge's wind pressure resistance.

[0064] Example 3

[0065] like Figure 9 As shown, in this embodiment, based on embodiment 1, a limiting component is provided on the second mounting base 2 to cooperate with each other. The limiting component includes a limiting block 32 disposed on the second mounting base 2. When the hinge is opened to a preset angle, the limiting block 32 and one side of the second connecting rod 4 abut against each other. When the second mounting base is unfolded to a set angle, one side of the second connecting rod 4 abuts against the limiting block 32, so as to realize that the first mounting base and the second mounting base can unfold or overlap within the set angle.

[0066] Example 4

[0067] like Figure 10 As shown, this embodiment, based on embodiment 1, adds a first reinforcing connecting rod 81 and a second reinforcing connecting rod 82. One end of the first reinforcing connecting rod 81 is hinged to the second mounting base 2; both ends of the second reinforcing connecting rod 82 are respectively hinged to the first reinforcing connecting rod 81 and the second connecting rod 4, wherein the first reinforcing connecting rod 81 is hinged to the lower surface of the second mounting base 2, and the second reinforcing connecting rod 82 is hinged to the upper surface of the middle part of the second connecting rod 4. This achieves multi-link assistance to the six-link linkage in bearing force, dispersing the destructive force on the hinge itself, thereby enhancing the safety protection effect of the hinge, and at the same time assisting the six-link structure in improving the load-bearing capacity of the hinge.

[0068] Example 5

[0069] like Figure 11 As shown, this embodiment, based on embodiment 1, adds a first reinforcing connecting rod 81 and a second reinforcing connecting rod 82. One end of the first reinforcing connecting rod 81 is hinged to the second mounting base 2. Both ends of the second reinforcing connecting rod 82 are respectively hinged to the first reinforcing connecting rod 81 and the second connecting rod 4. The first reinforcing connecting rod 81 is hinged to the lower surface of the second mounting base 2, and the second reinforcing connecting rod 82 is hinged to the end where the second connecting rod 4 and the fourth connecting rod 6 are hinged. The pivot for hinged between the second connecting rod 6 and the fourth connecting rod 6 passes through the second reinforcing connecting rod 82, the second connecting rod 4, and the fourth connecting rod 6 in sequence, hinged to the upper surface of the second connecting rod 4. This achieves multi-link assistance to the six-link linkage in bearing force, dispersing the destructive force on the hinge itself, thereby enhancing the safety protection effect of the hinge, and at the same time assisting the six-link structure in improving the load-bearing capacity of the hinge.

[0070] Example 6

[0071] like Figure 12As shown, the hinge in Embodiment 1 is also provided with an adjustable component 9. The adjustable component 9 connects the first connecting rod 3 and the third connecting rod 5 simultaneously, and is used to simultaneously adjust the rotation of the first connecting rod 3 and the second connecting rod 4. The adjustable component 9 includes an adjusting member 91 and an adjusting plate 92. The adjusting plate 92 is located below the first mounting base 1. The first mounting base 1 is provided with a first strip hole 101, a second strip hole 102, and a third strip hole 103. The length direction of the first strip hole 101, the second strip hole 102, and the third strip hole 103 is arranged along the length direction of the first mounting base 1. The ends of the first connecting rod 3 and the third connecting rod 5 are provided with rotating shafts, which pass through the second strip hole 2 and the third strip hole 3 respectively and are connected to the adjusting plate 92. A sealing member 7 and a first fixing member 11 are provided at the first strip hole 1, and the rotating shaft is arranged to pass through the sealing member 7, the first strip hole 1, the adjusting plate 92, and the first fixing member 11 in sequence for movable connection. The first mounting base 1 is provided with a first limiting hole 95, which is circular. The adjusting component 91 passes through the first limiting hole 95 and is connected to the adjusting plate 92. It is used to control the movement of the adjusting plate 92 in the length direction of the first mounting base 1, thereby driving the movement of the entire linkage assembly. The adjusting component 9 is used to adjust the movement distance of the entire linkage assembly, so that the multi-link full rotation point structure has an adjustment function, and the window sash can move relative to the window frame after the hinge is fixed.

[0072] In a preferred embodiment, the adjusting member 91 is an adjusting shaft with an eccentric structure. The first limiting hole 95 is circular, and the adjusting shaft passes through the first limiting hole 95 and connects to the adjusting plate 92. The adjusting shaft and the adjusting plate 92 are eccentrically fitted, and the movement of the adjusting plate 92 is controlled by the eccentric structure of the adjusting shaft. When the adjusting shaft is rotated, the adjusting plate 92 can drive the rotating shaft connected to the sealing member 7, the first connecting rod 3, and the third connecting rod 5 to move in the same direction relative to the first mounting base 1, making the adjustment movement distance controllable. This drives the connecting assembly to move relative to the first mounting base 1, and then causes the window sash to move relative to the window frame. This achieves the effect of compensating for deformation caused by excessive window weight through the adjustable function of the hinge, preventing the window frame and window sash from colliding and causing the window to be unable to open or close.

[0073] In a preferred embodiment, the first mounting base 1 is provided with a first limiting part 16, and the sealing member 7 is provided with a locking part 71 that cooperates with the first limiting part 16, so as to restrict the sealing member 7 to slide only in the same direction relative to the first mounting base 1. When the window sash moves relative to the window frame, the sealing performance of the hinge can be maintained, and the sealing member 7 can also be prevented from deviating from its initial position during use, which would cause the hinge to fail to seal. The first mounting base 1 is provided with a fixing member limiting point, and the first fixing member 11 cooperates with the fixing member limiting point to play an initial positioning role. When disassembling the hinge, the first fixing member 11 can be quickly positioned to prevent over-rotation that would prevent the hinge from being disassembled.

[0074] In a preferred embodiment, a shim is provided at the connection between the third connecting rod 5 and the adjusting plate 92. The shaft passes through the mounting hole of the third connecting rod 5, the strip hole of the first mounting base 1, and the adjusting plate 92 in sequence, and the third connecting rod 5, the shim, and the adjusting plate 92 are hinged to the first mounting base 1. The first mounting base 1 has positioning protrusions on both sides near the mounting hole of the third connecting rod 5, which can cooperate with the target object fixed to the first mounting base 1. When the hinge is subjected to a continuous or instantaneous maximum angle opening impact, it can effectively prevent the first mounting base 1 from bending into a sickle shape, thereby improving the safety and stability of the hinge.

[0075] In a preferred embodiment, a gasket is provided at the connection between the first mounting base 1 and the fourth connecting rod 6. The fourth connecting rod 6 and the gasket are hinged to the first mounting base 1 in sequence by passing a pivot through the mounting hole of the fourth connecting rod 6. There is sufficient space at both ends of the hinge point between the fourth connecting rod 6 and the first mounting base 1 to provide a fixing piece or a screw hole, which effectively prevents the first mounting base 1 from being deformed when the connecting rod is under force. A gasket is held at the hinge point of the second connecting rod 4 and the third connecting rod 5. The pivot passes through the second connecting rod 4, the gasket and the third connecting rod 5 in sequence to achieve the hinge. The second connecting rod 4 is provided with a mounting hole. The second connecting piece is hinged to the second mounting base 2 by passing a pivot through the mounting hole of the second connecting rod 4. A gasket is held at the hinge point of the second connecting rod 4 and the fourth connecting rod 6. The pivot passes through the second connecting rod 4, the gasket and the fourth connecting rod 6 in sequence to achieve the hinge. This realizes a six-link full rotation point structure of the hinge, so that the hinge can be used normally. The two ends of the reinforcing connecting rod 8 are respectively connected to the second connecting rod 4 and the second mounting base 2. Setting the reinforcing connecting rod 8 can increase the connection points between the window frame and the window sash, thereby enhancing the safety of the window, and at the same time assisting the six-bar structure to improve the load-bearing capacity of the hinge.

[0076] Example 7

[0077] like Figure 13 As shown, in this embodiment, based on embodiment 6, the adjustment component 9 further includes a swing plate 94 and a fixed shaft 93. The swing plate 94 has a through hole for the fixed shaft 93 to pass through and connect to the adjustment plate. The adjustment plate 92 has a fourth strip hole 104. The adjustment component 91 passes through the first limiting hole 95 and the fourth strip hole 104 to connect with the swing plate 94. The adjustment component 91 is an adjustment shaft with an eccentric structure. The first limiting hole 95 is circular. The adjustment shaft passes through the first limiting hole 95 and eccentrically engages with the swing plate 94 to control the movement of the adjustment plate 92.

[0078] Example 8

[0079] like Figure 14As shown, the difference between this embodiment and embodiment 6 is that the limiting hole 95 is elongated, and the length direction of the limiting hole 95 is set along the width direction of the first mounting base 1. The adjusting shaft passes through the limiting hole 95 and is connected to the adjusting plate 92. The movement of the adjusting plate is controlled by the eccentric structure of the adjusting shaft 93.

[0080] Example 9

[0081] like Figure 15 As shown, this embodiment differs from Embodiment 6 in that the adjusting assembly 9 includes an adjusting member 91 and an adjusting plate 92. The adjusting member 91 is an adjusting screw, which has a fourth limiting part 911. The first limiting hole 95 is an elongated through hole with an enlarged hole 17 and a third limiting part 18. The adjusting plate 92 has a second engaging part 922 that mates with the first limiting hole 95. The second engaging part 922 is perpendicular to the adjusting plate 92, allowing it to pass through the first limiting hole 95, be positioned above the first mounting base 1, and be engaged with the third limiting part 18. Both ends of the second engaging part 922 have grooves or through holes that allow the adjusting screw to be horizontally embedded. The second engaging part 922 also has screw holes for engaging with the adjusting screw. The second locking part 922 moves along the length direction of the first limiting hole 95 when the screw is rotated and adjusted. A second limiting hole 19 is provided to cooperate with the second limiting part 921 to restrict the adjusting plate 92 to slide only in the same direction relative to the first mounting base 1. When the window sash moves relative to the window frame, the hinge can maintain its sealing performance. When the adjusting screw is rotated, the adjusting plate 92 can drive the rotating shaft connected to the sealing member 7, the first connecting rod 3, and the third connecting rod 5 to move relative to the first mounting base 1, so that the adjustment movement distance is controllable. This drives the connecting assembly to move relative to the first mounting base 1, and then the window sash moves relative to the window frame. This achieves the effect of compensating for deformation caused by excessive window weight through the adjustable function of the hinge.

[0082] Example 10

[0083] like Figure 16As shown, this embodiment differs from embodiment 6 in that the adjusting assembly 9 includes an adjusting member 91 and an adjusting plate 92. The adjusting member 91 is hinged to the adjusting plate 92. The rotating shaft connected to the sealing member 7, the first connecting rod 3, and the third connecting rod 5 is hinged to the adjusting plate 92. The first mounting base 1 is provided with a first strip hole 101, a second strip hole 102, and a third strip hole 103. The rotating shaft connected to the sealing member 7, the first connecting rod 3, and the third connecting rod 5 is slidably disposed in the first strip hole 101, the second strip hole 102, and the third strip hole 103, respectively. The rotating shaft connected to the sealing member 7, the first connecting rod 3, and the third connecting rod 5 is connected to a connecting rod assembly. The adjusting member 91 is provided with a protruding member 912. The first mounting base 1 is provided with a recessed member 913 that meshes with the protruding member 912. The first mounting base 1 is provided with a first limiting hole 95. The first limiting hole 95 is a strip-shaped hole. The adjusting member 91 passes through the first limiting hole 95 and slides on the first mounting base 1. The adjusting plate 92 is provided with a second limiting part. The first mounting base 1 is provided with an enlarged part that cooperates with the second limiting part 921 to restrict the adjusting plate 92 to slide only in the same direction relative to the first mounting base 1. The adjusting member 91 is provided with a threaded hole for connecting to a screw. After adjusting the movement distance, the screw is tightened to prevent backflow. When the adjusting member 91 is rotated, the adjusting plate 92 can drive the rotating shaft connected to the sealing member 7, the first connecting rod 3, and the third connecting rod 5 to move relative to the first mounting base 1, so that the adjustment movement distance is controllable. This drives the connecting assembly to move relative to the first mounting base 1, and then the window sash moves relative to the window frame. This achieves the effect of compensating for deformation caused by excessive window weight through the adjustable function of the hinge.

[0084] Of course, this application may have many other implementation methods. Based on this implementation method, other implementation methods obtained by those skilled in the art without any creative effort are all within the scope of protection of this application.
