Description

Technical Field

[0001] This invention belongs to the field of hardware technology, specifically relating to a hinge linkage assembly, a hinge, and a window. Background Technology

[0002] Windows are a fundamental component of modern buildings, fulfilling users' needs for lighting, ventilation, and aesthetics. Based on their opening mechanism, existing windows can be broadly categorized into casement windows, sliding windows, and awning windows. Casement windows are a widely used type, where the frame and sash are connected by hinges, allowing the sash to rotate outwards or inwards relative to the frame, thus opening and closing the window.

[0003] However, existing hinges suffer from technical problems such as complex structure or inconvenient manufacturing. Specifically, hinges are mainly composed of a mounting base, a support arm, and a linkage assembly. The mounting base and support arm are used to connect the window frame and the window sash, respectively. Therefore, when the window sash is opened relative to the window frame, the linkage assembly is mainly responsible for bearing the force on the window sash (especially when the window sash is in the open state relative to the window frame), in addition to constraining the movement trajectory of the window sash relative to the window frame. Furthermore, hinges are typically made from stainless steel strips through stamping. The thickness of the sheet material used to make hinges is usually around 2mm. That is, stainless steel sheets with a thickness of around 2mm are relatively easy to process and form using a punch press. However, the linkage assembly made from sheets with a thickness of around 2mm often has certain deficiencies in load-bearing capacity. To solve this problem, the number of linkages is usually increased, generally three or four linkages. For example, the invention patent with application number 201420221645.3 discloses a friction hinge for windows. Referring to the accompanying drawings, we can see that this technical solution uses three linkages (first connecting plate 3, second connecting plate 4, and third connecting plate 8) to form the linkage assembly.

[0004] Furthermore, due to industry standards, the thickness of the hinge body is generally limited to approximately 11.5mm (height) and 22-24mm in width. Therefore, the only breakthroughs that can be made in the connecting rod assembly are through technical improvements to its thickness (e.g., increasing the thickness of the connecting rod while reducing the number of connecting rods). However, if simply increasing the thickness of the connecting rod assembly to improve the hinge's load-bearing capacity (which reduces the number of connecting rods) presents the following technical challenges: due to the inherent properties of stainless steel, the stainless steel strip used to manufacture the connecting rod assembly is prone to cracking during the stamping process. In other words, stainless steel hardens drastically during plastic deformation, which reduces its plasticity and impact toughness. This increases damage or wear to the stamping die and also affects the toughness of the workpiece, meaning that the connecting rod is prone to brittle fracture under stress. Stainless steel strip requires greater deformation, blanking, and tensile forces than ordinary steel during stamping. For example, a 70-ton stamping press is needed to complete the stamping work when the thickness of the stainless steel strip is only 3mm. On the other hand, simply increasing the thickness of the stainless steel strip not only makes processing more difficult, but also results in lower precision of the finished product due to the relatively high yield strength of stainless steel.

[0005] Furthermore, assuming we disregard the problems caused by the aforementioned stamping process, and reduce the number of links in the linkage assembly to two by thickening the sheet metal, further, when the number of links is reduced to two, the positions of the links need to be rearranged. In this case, at least a portion of the length of the two links will overlap relative to the width of the hinge. That is, the combined width of these two portions of the two links cannot exceed 24mm. And when the hinge is folded (when the window sash is closed relative to the window frame, meaning the hinge is folded), relative to the length of the hinge... In the direction of degree, since the first link needs to pass over the end of the second link, and since a pin needs to be installed at the end while ensuring connection strength, the width of the end of the second link will be relatively large. At this time, a corresponding clearance must be provided on the first link. As a result, this clearance becomes the area with the smallest width on the first link. In other words, although the thickness of the first link increases, the clearance reduces the width of the first link. That is to say, this clearance becomes a weak point in the link assembly, which will also reduce the load-bearing capacity of the link assembly. Summary of the Invention

[0006] In view of this, the purpose of the present invention is to provide a hinge linkage assembly, a hinge, and a window with a simple and reasonable structure and good load-bearing performance.

[0007] To solve the above-mentioned technical problems, the technical solution used in this invention is as follows:

[0008] A hinge linkage assembly includes a first link and a second link, the first link and the second link being rotatably connected and capable of relative movement and unfolding or folding. The first link includes a first body and a first extension, the first extension being fixed to the first body. The second link includes a second body and a second extension, the second extension being fixed to the second body. When the first link and the second link are in a folded state, the first extension and the second extension overlap in the width direction relative to the first body or the second body. A clearance is provided on one side of the first extension in the width direction, the thickness of the clearance being less than the thickness of the first extension. At least a portion of the end of the second extension is inserted into the clearance. Relative to the length direction of the first link, the clearance is located between the end of the first extension and the first body.

[0009] As a further improvement to the hinge link assembly, when the first link and the second link are in a folded state, the width of the first extension and the second extension overlapping is not greater than the width of the first body or the second body.

[0010] As a further improvement to the hinge link assembly, the first body and the second body are stacked relative to the thickness direction of the first link or the second link, and the first extension is bent relative to the first body and / or the second extension is bent relative to the second body, such that the first extension and the second extension can be superimposed relative to the width direction of the first body or the second body.

[0011] As a further improvement to the linkage assembly of the hinge, in the width direction of the first extension, the sidewall of the clearance is recessed inward relative to the sidewall of the first extension, and in the thickness direction of the first extension, one side of the first extension corresponding to the clearance is open and the other side is closed.

[0012] As a further improvement to the linkage assembly of the hinge, in the thickness direction of the first extension, the bottom of the first extension corresponding to the clearance position is in an open state, and the top is in a closed state.

[0013] As a further improvement to the linkage assembly of the hinge, a first recess is provided on one side of the first body in the thickness direction, the outline of the first recess being smaller than the outline of the first body, and / or a second recess is also provided on one side of the first extension in the thickness direction, the outline of the second recess being smaller than the outline of the first extension.

[0014] A hinge includes a mounting base, a support arm, and a linkage assembly as described above. Both the mounting base and the support arm are connected to the linkage assembly, allowing the support arm to reciprocate relative to the mounting base. A first link and a second link of the linkage assembly are hinged together. One end of the first link is slidably connected to the mounting base and rotatable relative to it, and the other end is slidably connected to the support arm and rotatable relative to it. One end of the second link is hinged to the mounting base, and the other end is hinged to the support arm.

[0015] As a further improvement to the hinge, the mounting base includes a body and an adapter. The body has a first connecting portion on one side in the width direction and a first protrusion on the other side. The adapter has a second connecting portion on one side in the width direction and a second protrusion on the other side. The second connecting portion is used to cooperate with the first connecting portion to form a connection, and the first protrusion and the second protrusion are respectively located on both sides of the axis of the mounting base.

[0016] As a further improvement to the hinge, the axis of the first connecting part forms an angle with the axis of the body, the axis of the second connecting part forms an angle with the axis of the adapter, and the axes of the first connecting part and the second connecting part are complementary.

[0017] As a further improvement to the hinge, when the first connecting part is connected to the second connecting part, the first convex strip and the second convex strip are parallel to each other.

[0018] As a further improvement to the hinge, the first connecting portion and the second connecting portion engage with each other relative to the width direction of the body.

[0019] As a further improvement to the hinge, the first connecting part is a groove, and the second connecting part is connected in the groove, or the second connecting part is a groove, and the first connecting part is connected in the groove.

[0020] As a further improvement to the hinge, a locking member is provided at one end of the adapter relative to the second connecting portion. The locking member is connected to the adapter and is used to fix the adapter and / or the body in the mounting position.

[0021] As a further improvement to the hinge, the axis of the locking member forms an angle with the transverse axis of the mounting base, and / or the axis of the locking member forms an angle with the longitudinal axis of the mounting base, and the head of the locking member faces the side of the adapter opposite to the second protrusion.

[0022] As a further improvement to the hinge, after the body and the adapter are connected, a second positioning block is provided on one end of the adapter relative to the second connecting part, and a second positioning groove is provided on the body to cooperate with the second positioning block.

[0023] As a further improvement to the hinge, a first bend is provided on one end of the body relative to the first connecting part, and a buckle is provided on one or both sides of the first bend in the width direction. The buckle is used to make the first bend engage with the C-shaped groove of the window frame.

[0024] As a further improvement to the hinge, a second bend is provided at one end of the support arm. The second bend is used to connect the window sash. An adjustment mechanism is also provided on the second bend, which can finely adjust the position of the window sash relative to the window frame in the X-axis, Y-axis, or Z-axis respectively.

[0025] As a further improvement to the hinge, the adjustment mechanism includes a movable block, a first adjustment member, a second adjustment member, and a third adjustment member. The movable block is movably connected to the second bending portion. The first adjustment member, the second adjustment member, and the third adjustment member are all connected to the movable block and / or the second bending portion. The first adjustment member, the second adjustment member, and the third adjustment member are arranged relative to the movable block along the Z-axis, X-axis, and Y-axis, respectively. The first adjustment member, the second adjustment member, and the third adjustment member are used to adjust the movement of the movable block relative to the mounting base along the Z-axis, X-axis, and Y-axis, respectively.

[0026] As a further improvement to the hinge, a guide hole is provided on the second bending portion, and a protrusion is provided on the movable block. The protrusion is placed in the guide hole and can move relative to the guide hole. The first adjusting member is connected to the protrusion and abuts against the second bending portion.

[0027] The support arm is also provided with a receiving groove, the second adjusting member is rotatably connected to the receiving groove, and the second adjusting member is connected to the movable block;

[0028] The third adjusting member is connected to the second bending portion, and the third adjusting member abuts against the connecting rod assembly of the hinge.

[0029] A window includes a window frame, a window sash, and a hinge as described above, wherein a mounting base of the hinge is connected to the window frame, and a support arm of the hinge is connected to the window sash.

[0030] Compared with the prior art, the beneficial effects of the present invention are mainly reflected in the following aspects: By setting a clearance on one side of the width direction of the first extension, when the linkage assembly or hinge is in a folded state, at least part of the end of the second extension is placed in the clearance, thereby enabling the linkage assembly to complete the constraint of the movement trajectory of the arm relative to the mounting seat using only two links (the first link and the second link); at the same time, since the thickness of the clearance is less than the thickness of the first extension, the clearance can still (partially) accommodate the second extension without destroying the overall width of the first extension. In other words, the overall structural strength of the first extension or the first link is effectively improved, thereby improving the load-bearing performance of the hinge during use.

[0040] The technical solution of the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention. In this embodiment, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present invention and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the present invention.

[0041] It should be noted that when one element is considered to be "connected" to another element, it can be directly connected to and integrated with the other element, or there may be an intervening element present. The terms "mounted," "one end," "the other end," and similar expressions used in this invention are for illustrative purposes only.

[0042] like Figure 1-4 As shown, this embodiment provides a hinge linkage assembly, which includes a first link 1 and a second link 2. The first link 1 and the second link 2 are connected by a pin, and the first link 1 and the second link 2 can move or rotate relative to each other, thereby allowing the linkage assembly 12 to be unfolded or folded. Further, the first link 1 includes a first body 3 and a first extension 4, the first extension 4 being integrally formed with the first body 3; the second link 2 includes a second body 5 and a second extension 6, the second extension 6 being integrally formed with the second body 5.

[0043] Furthermore, when the first link 1 and the second link 2 are in a folded state, or when the link assembly 12 is in a folded state, in the lateral direction, the combined width of the first extension 4 and the second extension 6 is not greater than the width of the first main body 3 or the second main body 5. Since the end of the second extension 6 needs to be drilled and hinged to the mounting base 10 through a pin, the diameter at the end (drilled hole) of the second extension 6 will be greater than the overall width of the second extension 6, provided that the connection strength is guaranteed. Furthermore, due to industry standards (the overall width of the hinge generally does not exceed 24mm), when the first link 1 and the second link 2 are in a folded state, that is, when the first extension 4 and the second extension 6 are superimposed on each other in the width direction relative to the first body 3 or the second body 5, or in other words, in the lateral direction, the first extension 4 and the second extension 6 are superimposed on each other; in order to ensure that the superimposed width of the first extension 4 and the second extension 6 does not exceed the relevant regulations, it is necessary to provide a clearance 7 on one side of the width direction of the first extension 4, so that at least part of the end of the second extension 6 can be inserted into the clearance 7. Relative to the length direction of the first link 1, the clearance 7 is located between the end of the first extension 4 and the first body 3.

[0044] Furthermore, the thickness of the first main body 3 and the first extension 4 is greater than the thickness of the second main body 5 and the second extension 6. In the width direction of the first extension 4, the sidewall of the clearance 7 is concave inward relative to the sidewall of the first extension 4. Relative to the thickness direction of the first extension 4, one side of the first extension 4 corresponding to the clearance 7 is open, and the other side is closed; or, relative to the width direction of the first extension 4, the sidewall of the clearance 7 is concave inward relative to the sidewall of the first extension 4, forming an angle. In this embodiment, in the thickness direction of the first extension 4, the bottom of the first extension 4 corresponding to the clearance 7 is open, and the top is closed. That is, the portion that closes the clearance 7 constitutes a reinforcing structure of the first extension 4. Specifically, the open side of the first extension 4 corresponding to the clearance 7, while accommodating the second extension 6, does not disrupt the overall width of the first extension 4, thereby enabling the first connecting rod 1, or the first extension 4, to maintain its structural strength. In other words, the load-bearing capacity of the first connecting rod 1 is effectively improved in both the transverse and longitudinal directions. Furthermore, once the hinge is installed on the window, it will be subjected to a force in the lateral direction, such as when the window sash is pushed open or when air blows onto the window sash; at the same time, the hinge will also be subjected to a force in the longitudinal direction, such as the weight of the window sash. In other words, the structure enclosed at the top and / or bottom (in the thickness direction) of the clearance 7 is equivalent to forming a reinforcement of the first extension 4, thereby improving the load-bearing capacity of the hinge linkage assembly 12, or the hinge, in the longitudinal and lateral directions.

[0045] like Figure 1-4 As shown, in a preferred embodiment, in the thickness direction of the first link 1 or the second link 2, the first body 3 and the second body 5 are stacked, and the second extension 6 is bent relative to the second body 5 and / or the first extension 4 is bent relative to the first body 3, so that the first extension 4 and the second extension 6 can be superimposed along the width direction of the first body 3 or the second body 5, or in other words, the first extension 4 and the second extension 6 can be superimposed in the lateral direction; the bending of the second extension 6 relative to the second body 5 and / or the bending of the first extension 4 relative to the first body 3 helps the second link 2 and / or the first link 1 to form a reliable connection with the mounting base 10 or the support arm 11; furthermore, if the second extension 6 is not bent relative to the second body 5, then the length of the pin will inevitably be extended, that is, the length of the pin will be greater than the thickness of the first extension 4. In this case, the part of the structure (reinforcing member) enclosed at the top of the clearance 7 will be destroyed, thereby destroying the load-bearing performance of the hinge link assembly 12.

[0046] like Figure 2 As shown, in a preferred embodiment, a first recess 8 is provided on one side of the first body 3 in the thickness direction, the outline of the first recess 8 being smaller than the outline of the first body 3, and / or a second recess 9 is provided on one side of the first extension 4 in the thickness direction, the outline of the second recess 9 being smaller than the outline of the first extension 4. The provided first recess 8 and / or second recess 9 can save material usage, that is, reduce the manufacturing cost of the hinge. Furthermore, if the outline of the first recess 8 is smaller than the outline of the first body 3, then the edge outline of the first body 3 essentially forms the skeleton of the first body 3, meaning that the amount of material used is reduced while meeting the load-bearing strength requirements of the first body 3.

[0047] like Figure 5-8As shown, this embodiment also provides a hinge, which includes a mounting base 10, a support arm 11, and a hinge linkage assembly 12 as described above. The mounting base 10 and the support arm 11 are both connected to the hinge linkage assembly 12, so that the support arm 11 can reciprocate relative to the mounting base 10, that is, the support arm 11 can be unfolded or folded relative to the mounting base 10. The first link 1 and the second link 2 of the hinge linkage assembly 12 are hinged by a pin. One end of the first link 1 is slidably connected to the mounting base 10 and can rotate relative to the mounting base 10. That is, the mounting base 10 has a strip-shaped through hole and forms a slide. The first link 1 is connected to the mounting base 10 by the pin. In other words, one end of the pin can slide along the length of the slide, and the other end is fixed to the first link 1. Similarly, the other end of the first link 1 is slidably connected to the support arm 11 and can rotate relative to the support arm 11. That is, the support arm 11 has a strip-shaped through hole and forms a slide. The first link 1 is connected to the support arm 11 by the pin. One end of the pin can slide along the slide on the support arm 11, and the other end of the pin is fixed to the first link. Furthermore, one end of the second link 2 is hinged to the mounting base 10 via a pin, and the other end is hinged to the support arm 11 via a pin; furthermore, in addition to bearing force, the hinge link assembly 12 is also used to constrain the movement trajectory of the support arm 11, such as constraining the opening angle of the window sash.

[0048] like Figure 6 , 7As shown, in a preferred embodiment, the mounting base 10 includes a body 13 and an adapter 14. A first connecting portion 15 is provided on one side of the body 13 in the width direction, and a first protrusion 16 is provided on the other side of the body 13 opposite to the first connecting portion 15. The first protrusion 16 is integrally formed with the body 13, and in this embodiment, the first protrusion 16 extends from one end to the other along the length direction of the body 13. The first protrusion 16 is used to create a locking mechanism between the body 13, or the mounting base 10, and one side of the C-shaped groove on the window frame profile, thus facilitating the connection and stress distribution between the body or the mounting base 10 and the window frame profile. Further, a second connecting portion 17 is provided on one side of the adapter 14 in the width direction, and a second protrusion 18 is provided on the other side of the adapter 14. The second protrusion 18 is integrally formed with the adapter 14, and in this embodiment, the second protrusion 18 extends from one end to the other along the length direction of the adapter 14. Furthermore, the second connecting part 17 is used to cooperate with the first connecting part 15 to form a connection, and the first protrusion 16 and the second protrusion 18 are respectively located on both sides of the axis of the mounting base 10. Furthermore, when the hinge is installed onto the profile, relative to the width of the body 13, the first protrusion 16 on one side of the body 13 is first inserted into the opening of the C-groove of the window frame profile, and finally the first protrusion 16 and the C-groove are engaged. On the other side of the body 13, since there is no first protrusion 16, it can be directly inserted into the C-groove (if the first protrusion 16 is provided on both sides of the body, the width of the body 13 will be greater than the opening width of the C-groove, that is, the body 13 will not be able to be engaged smoothly with the C-groove of the profile, that is, the hinge mounting base 10 can only be inserted into the C-groove of the window frame at an angle). At this time, the side of the body 13 without the first protrusion 16 cannot form an effective force with the profile. The adapter 14, which is provided to cooperate with the body, is equivalent to giving the two sides of the body 13 the first protrusion 16 and the second protrusion 18 respectively, thereby increasing the reliable force after the mounting base 10 is connected to the profile, that is, increasing the stability of the connection between the mounting base and the profile.

[0049] like Figure 6 , 7As shown, in a preferred embodiment, the axis of the first connecting portion 15 forms an angle with the axis of the body 13, and the axis of the second connecting portion 17 forms an angle with the axis of the adapter 14, and the axes of the first connecting portion 15 and the second connecting portion 17 are complementary; and relative to the width direction of the body 13, the first connecting portion 15 and the second connecting portion 17 engage with each other; further, in this embodiment, the first connecting portion 15 is a groove, and the second connecting portion 17 is connected in the groove, or the second connecting portion 17 is a groove, and the first connecting portion 15 is connected in the groove; after the first connecting portion 15 and the second connecting portion 17 engage, the body 13 and the adapter 14 can better resist the influence of the biasing force acting on the mounting base 10, that is, the second connecting portion 17 will not easily disengage from the first connecting portion 15 due to the influence of the biasing force. When the first connecting part 15 is connected to the second connecting part 17, the first protrusion 16 and the second protrusion 18 are parallel to each other, and relative to the width direction of the body 13, the first protrusion 16 and the second protrusion 18 are located on both sides of the body 13. Furthermore, since the axes of the first connecting part 15 and the second connecting part 17 are complementary, the adapter 14 can act as a wedge or filler, thereby enabling both sides of the body 13 to engage with the C-shaped groove of the profile. That is, the first protrusion 16 on one side of the body 13 engages with one side of the C-shaped groove, and the other side is engaged with the other side of the C-shaped groove by the second protrusion 18. In other words, while facilitating the installation of the hinge and the profile, it is equivalent to having the first protrusion 16 and the second protrusion 18 on both sides of the body 13, thereby effectively improving the stability of the body 13 after being connected to the profile, that is, avoiding or reducing the influence of the offset force on the mounting base 10.

[0050] Specifically, when installing the hinge onto the profile, relative to the width of the body 13, the first protrusion 16 on one side of the body 13 is first inserted into the opening of the C-groove of the window frame profile, and finally the first protrusion 16 and the C-groove form a locking mechanism. The other side of the body 13, lacking the first protrusion 16, can be directly inserted into the C-groove. (If the first protrusion 16 were provided on both sides of the body, the width of the body 13 would be greater than the opening width of the C-groove, meaning the body 13 would not be able to smoothly form a locking mechanism with the C-groove of the profile.) (Clamping); At this time, the side of the body 13 without the first protrusion 16 cannot form an effective force-bearing or load-bearing relationship with the profile. That is to say, when the side of the body 13 or the mounting base 10 without the first protrusion 16 is subjected to an upward biasing force, the relative stability between the body 13 and the window frame profile will be mainly borne by the fixing screws (screws fixed to the body 13 and the profile). Otherwise, the side of the body 13 without the first protrusion 16 will easily detach from the C-groove of the profile. Further, the adapter 14 is similarly placed into the C-groove of the window frame profile. At the same time, the adapter 14 is moved along the length of the C-groove until the first connecting part 15 on the body 13 and the second connecting part 17 on the adapter 14 engage with each other. At this point, it is equivalent to setting the first protrusion 16 and the second protrusion 18 on both sides of the body 13, so that the body 13 can form a stable and fixed connection with the C-groove of the profile, that is, avoiding or reducing the influence of the biasing force on the mounting base 10.

[0051] like Figure 5-7 As shown, in a preferred embodiment, a locking member 19 is further provided at one end of the adapter 14 relative to the second connecting portion 17. The locking member 19 is connected to the adapter 14 and is used to fix the adapter 14 and / or the body 13 in the mounting position. In this embodiment, the locking member 19 is a set screw, that is, the set screw and the adapter 14 are connected by threads; by rotating the set screw, the end of the set screw can abut against the profile and apply a thrust to the profile, thereby fixing the adapter 14 on the C-groove of the profile.

[0052] like Figure 5-7As shown, in a preferred embodiment, the axis of the locking member 19 forms an angle with the transverse axis of the mounting base 10, and / or the axis of the locking member 19 forms an angle with the longitudinal axis of the mounting base 10, and the head of the locking member 19 faces the side of the adapter 14 opposite to the second protrusion 18. Specifically, when the axis of the locking member 19 forms an angle with the transverse axis of the mounting base 10, when the locking member 19 (set screw) is locked, that is, as the push end of the set screw extends, a thrust is generated on the adapter 14, which forces the adapter 14 to move along the axial direction of the C-groove, that is, causing the second connecting part 17 to move toward the first connecting part 15 and form a tight engagement or abutment (of course, one end of the body 13 will abut against the side wall of the window frame). Furthermore, when the axis of the locking member 19 forms an angle with the longitudinal axis of the mounting base 10, and the head of the locking member 19 faces the side of the adapter 14 opposite to the second protrusion 18, as the pushing end of the set screw extends, the adapter 14 will generate an upward thrust relative to the C-groove, thereby causing the second protrusion 18 on the adapter 14 to abut against the C-groove. In other words, when the locking member 19 is locked, the adapter 14 will be subjected to an axial thrust and a radial thrust relative to the C-groove, thereby enabling the adapter 14 to form a more reliable connection with the body 13.

[0053] like Figure 7 As shown, in a preferred embodiment, after the body 13 is connected to the adapter 14, a second positioning block 20 is provided on one end of the adapter 14 relative to the second connecting portion 17, and a second positioning groove 21 is provided on the body 13 to cooperate with the second positioning block 20. In this embodiment, the second positioning block 20 is spaced apart from the adapter 14 by a preset distance relative to the thickness direction of the adapter 14, that is, a gap is formed. Furthermore, when the first connecting portion 15 and the second connecting portion 17 on the body 13 and the adapter 14 engage with each other, the bottom wall of the second positioning groove 21 is embedded in the gap. That is to say, the end of the body 13 is prevented from tilting upwards due to force, and the body 13 is also prevented from being deflected relative to the adapter 14 due to the biasing torque, thereby further improving the reliability of the connection between the mounting base and the profile C-groove.

[0054] like Figure 7 , 8As shown, in a preferred embodiment, a first bending portion 22 is further provided on one end of the main body 13 relative to the first connecting portion 15, and a latch 23 is further provided on one or both sides of the first bending portion 22 in the width direction. Furthermore, the latch 23 is slidably connected to the first bending portion 22. Additionally, a return spring 24 is included, with one end abutting against the latch 23 and the other end abutting against the first bending portion 22. The return spring 24 is used to cause the end of the latch 23 to protrude from one side of the first bending portion 22. That is, when the latch 23 is engaged with the C-shaped groove on the longitudinal side of the window frame, the hinge can no longer move along the axis of the C-shaped groove in the transverse direction, or in other words, the window sash cannot move relative to the window frame in the transverse direction. Furthermore, a sliding groove (not shown) is provided on the first bending portion 22, and the buckle 23 is placed in the sliding groove. The buckle 23 can slide relative to the sliding groove or the first bending portion 22. Specifically, when the buckle 23 is slidably connected with the bending portion, a return spring 24 is also included. The return spring 24 is placed in the sliding groove. One end of the return spring 24 abuts against the buckle 23, and the other end abuts against the first bending portion 22. The return spring 24 is used to push the end of the buckle 23 to protrude from one side of the first bending portion 22. That is, when the buckle 23 is engaged with the C-shaped groove on the longitudinal side of the window frame, the hinge can no longer move along the C-shaped groove in the transverse direction, or in other words, the window sash cannot move in the transverse direction relative to the window frame. After the hinge mounting base 10 engages with the C-shaped groove in the lateral direction, it moves along the C-shaped groove until the latch 23 approaches the opening of the lateral C-shaped groove of the window frame. At this point, the edge of the opening of the C-shaped groove applies a squeezing force to the latch 23, causing the latch 23 to retract into the first bend 22. Finally, as the mounting base 10 moves further and abuts against the side of the window frame, the end of the latch 23 has passed the opening of the C-shaped groove. At this point, under the elastic force of the return spring, the end of the latch 23 extends out and engages with the C-shaped groove, thereby fixing the mounting base 10 to the window frame. Furthermore, a first bend 22 and a buckle that cooperates with the first bend 22 are provided on the body 13 to facilitate window installation. That is, when the buckle 23 on the first bend 22 is engaged with the window frame, the hinge can be pre-fixed to the window frame, thus freeing up the worker's other hand (without the first bend and buckle 23, when it is necessary to fix the hinge (body 13) to the window frame, the worker needs to fix the hinge by hand to prevent it from shifting relative to the C-groove of the profile), thereby facilitating window installation and improving window installation efficiency.

[0055] like Figure 5 , 7As shown in Figure 8, in a preferred embodiment, a second bending portion 25 is also provided at one end of the support arm 11. The second bending portion 25 is used to hold and fix the support arm 11 to the C-shaped groove on the side of the window sash. In this embodiment, a rotating buckle 26 is provided on the second bending portion 25. The rotating buckle 26 also enables the support arm 11 to be held to the C-shaped groove of the window sash profile. Of course, the rotating buckle 26 in this embodiment can also be a sliding buckle 23 as described above.

[0056] like Figure 7 As shown, in a preferred embodiment, an adjustment mechanism is disposed on the second bend 25, and the adjustment mechanism is used to fine-tune the position of the window sash relative to the window frame. Further, the adjustment mechanism includes a movable block 33, a first adjusting member 27, a second adjusting member 28, and a third adjusting member 29. The movable block 33 is movably connected to the second bend 25. The first adjusting member 27, the second adjusting member 28, and the third adjusting member 29 are all connected to the movable block 33 and / or the second bend 25. The first adjusting member 27, the second adjusting member 28, and the third adjusting member 29 are arranged relative to the movable block 33 along the Z-axis, X-axis, and Y-axis, respectively, and are used to adjust the movement of the movable block 33 relative to the mounting base 10 along the Z-axis, X-axis, and Y-axis, respectively. Furthermore, adjusting the X, Y, and Z axis positions of the window sash relative to the window frame via the adjustment mechanism refers to the window sash being in the closed state relative to the window frame. Of course, adjustment of the mechanism is performed when the window sash is open relative to the window frame; that is, adjustment cannot be performed when the window sash is closed. By incorporating adjustment mechanisms on the hinges that allow for fine-tuning of the window sash relative to the window frame along the X, Y, or Z axes, the distance between the window sash and the window frame in the width, height, or thickness directions can be adjusted as needed. This ensures a good seal between the window sash and the frame, preventing rubbing against the frame during opening and closing. Compared to existing technologies, this provides clear adjustment boundaries, reduces the difficulty of hinge adjustment, improves the ease of hinge use, and also increases the efficiency of window assembly.

[0057] like Figure 7As shown, in the preferred embodiment, the first adjusting member 27 is a bolt or a set screw; in this embodiment, the first adjusting member 27 is a set screw. A guide hole 30 is also provided on the second bent portion 25, and a protrusion 31 is provided on the movable block 33. The protrusion 31 is placed inside the guide hole 30 and can move relative to the guide hole 30 (Z-axis). The first adjusting member 27 is screwed into the protrusion 31, and the first adjusting member 27 abuts against the second bent portion 25. In this embodiment, the end of the set screw (first adjusting member 27) abuts against the guide hole 30 (second bent portion 25). Further, the second adjusting member 28 is a bolt, and a receiving groove 32 is also provided on the second bent portion 25. The second adjusting member 28 is rotatably connected to the receiving groove 32, that is, the bolt head (second adjusting member 28) is held in the receiving groove 32, and the second adjusting member 28 is screwed into the movable member by threads. The third adjusting member 29 is a bolt or a set screw. In this embodiment, the third adjusting member 29 is a set screw. The third adjusting member 29 is screwed into the second bent portion 25 and abuts against the connecting rod assembly 12 of the hinge. Furthermore, in this embodiment, the second bent portion 25 is connected to the connecting rod assembly 12 of the hinge (the first end of the second connecting rod 2) by a pin, and the second bent portion 25, or the support arm 11, can slide a short distance along the axial direction of the pin. That is, by adjusting the third adjusting member 29, the support arm 11 can be finely adjusted relative to the mounting base 10 on the Z-axis.

[0058] This embodiment also provides a window, which includes a window frame, a window sash, and the hinges as described above. The hinge mounting base 10 is connected to the window frame, and the hinge arm 11 is connected to the window sash.

[0059] Compared with the prior art, the beneficial effects of the present invention are mainly reflected in the following aspects: By setting a clearance on one side of the width direction of the first extension, when the linkage assembly or hinge is in a folded state, at least part of the end of the second extension is placed in the clearance, thereby enabling the linkage assembly to complete the constraint of the movement trajectory of the arm relative to the mounting seat using only two links (the first link and the second link); at the same time, since the thickness of the clearance is less than the thickness of the first extension, the clearance can still (partially) accommodate the second extension without destroying the overall width of the first extension. In other words, the overall structural strength of the first extension or the first link is effectively improved, thereby improving the load-bearing performance of the hinge during use.
