Description

Technical Field

[0001] This invention relates to the field of door and window technology, and in particular to an upper hinge mechanism for assembly in doors and windows, a door and window equipped with the upper hinge mechanism, and a method for installing the door and window. Background Technology

[0002] Currently, such as Figure 1 As shown, the operable doors and windows installed in the building mainly include a fixed outer frame 10 fixed in the building, a door / window sash 20 that can be opened and closed and installed in the fixed outer frame 10, an upper hinge mechanism 30, and a lower hinge mechanism 40. The door / window sash 20 includes a sash frame 21 and a sash panel 22 installed in the sash frame 21. The sash panel 22 is usually glass. The upper hinge mechanism 30 is installed between the sash frame 21 and the fixed outer frame 10 at the upper corner of the door / window sash 20, and the lower hinge mechanism 40 is installed between the sash frame 21 and the fixed outer frame 10 at the lower corner of the door / window sash 20.

[0003] Existing upper and lower hinge mechanisms come in two types: separate and integrated. Regardless of whether they are separate or integrated, both mechanisms include a frame-side connecting assembly fixed to the fixed outer frame, a sash-side connecting assembly fixed to the sash frame, and a rotating connecting assembly. The rotating connecting assembly connects the frame-side and sash-side connecting assemblies. The sash-side connecting assembly rotates inward or outward relative to the frame-side connecting assembly, thereby opening or closing the door / window sash. Typically, the sash-side connecting assembly includes a sash-side fixing base and a sash-side hinge plate fixed by a fixing pin. The sash-side fixing base is used for fixed connection to the sash frame, and the sash-side hinge plate is used for connection to the rotating connecting assembly. Furthermore, the inner circumference of the fixed outer frame has a C-shaped groove for the frame-side connecting assembly to be inserted, and the outer circumference of the sash frame has a C-shaped groove for the sash-side connecting assembly to be inserted.

[0004] For the split-type upper and lower hinge mechanisms: before being assembled between the fixed outer frame and the door / window sash, the rotating connecting component and the sash-side hinge plate of the sash-side connecting component are integrated on the frame-side connecting component. The sash-side hinge plate and the sash-side fixing base are separate and not yet fixed by fixing pins. This makes the upper and lower hinge mechanisms split-type structures before installation, with the frame-side connecting component and the components integrated on it being separate from the sash-side fixing base of the sash-side connecting component. Thus, the installation process for doors and windows equipped with separate upper and lower hinge mechanisms is as follows: 1. Fix the frame-side connecting component and sash-side fixing base of the upper hinge mechanism into the C-groove of the fixed outer frame and the C-groove of the sash frame, respectively; fix the frame-side connecting component and sash-side fixing base of the lower hinge mechanism into the C-groove of the fixed outer frame and the C-groove of the sash frame, respectively; 2. Ensure that both the rotating connecting components of the upper and lower hinge mechanisms are in the open state; 3. At least two workers are required to lift the door / window sash and open the door / window. With the window sash in an open position relative to the fixed outer frame, the sash-side fixing base of the upper hinge mechanism and the sash-side hinge plate of the lower hinge mechanism must be precisely aligned. 4. Several workers lift the window sash and move it towards the fixed outer frame. After it is in place, an additional worker is needed to install the fixing pins of the upper and lower hinge mechanisms, securing the sash-side fixing base and hinge plate of both mechanisms. This completes the assembly of the window and door. However, the strength at the fixing points of the separate upper and lower hinge mechanisms (upper and lower sash fixing base and hinge plate) is relatively low, which can easily lead to malfunctions after a period of use.

[0005] For the integrated upper and lower hinge mechanisms: before being assembled between the fixed outer frame and the door / window sash, the frame-side connecting components, rotating connecting components, and sash-side connecting components are already connected, making the upper and lower hinge mechanisms a single, integrated structure before installation. Therefore, the installation process for doors and windows equipped with integrated upper and lower hinge mechanisms is as follows: 1. Fix the sash-side fixing base of the lower hinge mechanism to the outer periphery of the sash frame, and fix the sash-side fixing base of the upper hinge mechanism to the outer periphery of the sash frame; 2. Ensure that the rotating connecting components of both the upper and lower hinge mechanisms are in the open position; 3. The worker lifts the door / window sash, first inserting the frame-side connecting component of the lower hinge mechanism into the C-groove of the fixed outer frame, and then inserting the frame-side connecting component of the upper hinge mechanism into the C-groove of the sash frame; 4. Secure both the frame-side connecting components of the lower and upper hinge mechanisms to the fixed outer frame. This completes the assembly of the door / window. However, because the fixed outer frame has integrally formed ribs on both sides of the C-groove to create the C-groove, the door and window sash is slightly tilted during the process of inserting the frame-side connecting assembly of the lower hinge mechanism into the C-groove of the fixed outer frame. Specifically, the side of the door and window sash away from the fixed outer frame is slightly tilted downwards. Figure 2 As shown. In a tilted door or window sash, the frame-side connecting component of the upper hinge mechanism fixed at its upper corner will inevitably tilt upwards. Combined with the obstruction of the inner circumferential rib on the upper end of the fixed outer frame, it is difficult for the frame-side connecting component of the upper hinge mechanism to be inserted into the C-shaped groove at the upper end of the fixed outer frame, making the installation of the door or window sash very difficult.

[0006] To address the aforementioned issues, existing technology, specifically Chinese invention patent CN106715815B, discloses an angled hardware component. This angled hardware component is fastened to grooves cut into the bottom of both sides of the frame, simplifying the connection method of door and window sashes to the frame. However, this angled hardware component is an additional addition and has a complex structure, requiring high precision in its contour, resulting in high production costs and thus increasing the production cost of doors and windows. Summary of the Invention

[0007] In view of the shortcomings of the prior art described above, the purpose of the present invention is to provide an upper hinge mechanism, which is an integral structure, and enables the door and window sashes with the upper hinge mechanism fixed to the fixed outer frame to be installed simply and easily.

[0008] To achieve the above objectives, the present invention provides an upper hinge mechanism for assembly between a fixed outer frame and a sash frame of a door or window. The upper hinge mechanism includes an upper frame side connecting assembly for fixing to the fixed outer frame, an upper sash side connecting assembly for fixing to the sash frame, and an upper rotating connecting assembly. The upper sash side connecting assembly includes an upper sash side hinge plate and an upper sash side fixed base. The upper sash side hinge plate is connected to the upper frame side connecting assembly via the upper rotating connecting assembly.

[0009] The upper hinge mechanism is an integrated structure that keeps the upper frame side connecting component, the upper rotating connecting component and the upper fan side connecting component connected in sequence;

[0010] The upper hinge mechanism also includes a fulcrum assembly and an adjusting connection assembly. The upper fan side hinge plate is mounted on the upper fan side fixed base in a way that allows it to swing up and down via the fulcrum assembly. The end of the upper fan side hinge plate away from the upper frame side connecting assembly is connected to the upper fan side fixed base via the adjusting connection assembly. The adjusting connection assembly has an unlocked state that allows the upper fan side hinge plate to swing up and down around the fulcrum assembly, and a locked state that restricts the upper fan side hinge plate from swinging up and down around the fulcrum assembly.

[0011] When the adjustment connection assembly is in the unlocked state, the upper frame side connection assembly is tilted downward by swinging the end of the upper fan-side hinge plate connected to the adjustment connection assembly upward.

[0012] When the adjusting connection assembly is in the locked state, the upper fan-side hinge plate is in a horizontal state.

[0013] Based on the integrated structure of the upper hinge mechanism, this application includes a fulcrum component and an adjusting connection component within the upper hinge mechanism. This allows the upper fan-side hinge plate to swing up and down around the fulcrum component when the adjusting connection component is unlocked, and prevents it from swinging when locked. Thus, after fixing the upper fan-side connection component of the upper hinge mechanism into the fan mounting slot at the top of the fan frame, the entire upper hinge mechanism is fixed to the top of the fan frame. Subsequently, when the upper frame-side connection component of the upper hinge mechanism in this state is inserted into the frame mounting slot at the upper corner of the fixed outer frame, the adjusting connection component of the upper hinge mechanism is unlocked. This allows the end of the upper fan-side hinge plate connected to the upper rotating connection component to swing down, thereby causing the upper frame-side connection component connected to that end to swing down as well, resulting in the entire upper frame-side connection component tilting downwards. This allows the upper frame-side connection component to easily pass over the first mounting arm at the top of the fixed outer frame, forming the frame mounting slot, and easily insert itself into the frame mounting slot at the upper corner of the fixed outer frame. Afterwards, the locking state of the adjusting connection component of the upper hinge mechanism is restored. The end of the upper sash hinge plate connected to the upper rotating connection component then swings upwards until the upper sash hinge plate is horizontal, driving the upper frame connection component to insert into the frame mounting groove at the upper corner of the fixed outer frame. Finally, the upper frame connection component is fixed to the fixed outer frame, thus completing the assembly of the upper hinge mechanism in the door and window, and realizing the installation of the door and window sash with the integrated upper hinge mechanism on the fixed outer frame.

[0014] Clearly, the upper hinge mechanism involved in this application is an integrated structure with good structural strength. Installing it between the fixed outer frame and the sash frame of a door or window enhances the overall structural stability and makes the door or window more durable. Furthermore, by incorporating a fulcrum component and an adjusting connection component into the integrated upper hinge mechanism, this application allows the upper frame-side connection component to tilt downwards when installed in the fixed outer frame. This facilitates easy insertion of the upper frame-side connection component into the frame mounting groove at the upper corner of the fixed outer frame, simplifying the installation of the door or window sash with the integrated upper hinge mechanism within the fixed outer frame.

[0015] Furthermore, the preferred structure of the fulcrum assembly is as follows: the fulcrum assembly includes a vertically arranged fulcrum pin and a fulcrum through hole opened in the upper fan side fixing base. The upper end of the fulcrum pin is fixed in the upper fan side hinge plate, and the fulcrum pin is movably inserted through the fulcrum through hole. Thus, when the adjustment connection assembly is in the unlocked state, the upper fan side hinge plate can swing up and down around the fulcrum pin as the center through the cooperation of the fulcrum pin and the fulcrum through hole, and during the swinging process, the fulcrum pin will sway up and down in the fulcrum through hole.

[0016] Furthermore, the fulcrum assembly also includes a limiting groove formed in the upper fan-side fixing base. The limiting groove is connected to the bottom of the fulcrum through hole, and the groove wall is distributed around the periphery of the fulcrum through hole wall, so that the upper fan-side fixing base forms a limiting step at the connection between the fulcrum through hole and the limiting groove. The lower end of the fulcrum pin is fixed with a limiting flange, which is movably accommodated in the limiting groove and can abut against the limiting step. When the adjustment connection assembly is in the unlocked state, as the upper sash hinge plate swings up and down around the fulcrum pin, the upper sash hinge plate drives the fulcrum pin to oscillate up and down. Simultaneously, the limiting flange oscillates up and down within the limiting groove. During this process, the limiting step abuts against the upper side of the limiting flange, limiting the upward swing of the limiting flange and thus restricting the upward swing amplitude of the upper sash hinge plate. Similarly, the upper sash fixing base abuts against the lower side of the upper sash hinge plate, limiting its downward swing amplitude and thus restricting its downward swing amplitude. In this way, when the door / window sash with the fixed upper hinge mechanism is installed into the fixed outer frame, the up-and-down swing amplitude of the upper sash hinge plate is reliably limited to a reasonable range. This allows the upper frame connection assembly to easily insert into the frame mounting groove at the upper corner of the fixed outer frame while preventing collisions with the fixed outer frame due to excessive swing amplitude of the upper sash hinge plate. In addition, the limiting step can also constrain the limiting flange in the limiting groove, thereby preventing the fulcrum pin from coming out of the fulcrum through hole.

[0017] Preferably, the fulcrum pin is a one-piece metal component, and it is riveted and fixed to the upper hinge plate. In this way, the fulcrum pin itself has good structural strength, and its fixation to the upper hinge plate is reliable, thus improving the structural strength of the one-piece upper hinge mechanism.

[0018] Further, the preferred structure of the adjusting connection assembly is as follows: the adjusting connection assembly includes a vertically arranged adjusting pin, an adjusting through hole opened in the upper fan-side hinge plate, and a connecting hole opened in the upper fan-side fixed base. The adjusting pin includes an upper shaft section, a lower shaft section, and at least one adjusting protrusion radially protruding from the outer circumferential surface of the upper shaft section. The lower shaft section is rotatably connected to the connecting hole. The adjusting through hole includes a hole body section and a hole limiting section communicating with the side of the hole body section. The upper shaft section passes through the hole body section. When the adjusting pin is rotated to circumferentially align the adjusting protrusion with the hole limiting section, the adjusting protrusion can be located in the hole limiting section, and the adjusting connection assembly is in an unlocked state. When the adjusting pin is rotated to circumferentially displace the adjusting protrusion with the hole limiting section, the adjusting protrusion, the upper fan-side hinge plate, and the upper fan-side fixed base abut against each other from top to bottom, and the adjusting connection assembly is in a locked state. In this adjustable connection assembly, simply rotating the adjusting pin allows the assembly to be switched to the unlocked or locked state, making it convenient for workers to operate and facilitating the installation of door and window sashes with an integrated upper hinge mechanism on the fixed outer frame.

[0019] Preferably, the adjusting pin has one adjusting protrusion and the upper fan side hinge plate has one hole limiting part, which facilitates the production and manufacturing of the adjusting pin and the processing of the adjusting through hole in the upper fan side hinge plate.

[0020] Furthermore, the outer peripheral surface of the adjusting protrusion is an arc surface, and the outer peripheral surface of the adjusting protrusion and the outer peripheral surface of the upper shaft section are connected by an arc surface transition. The contour of the adjusting through hole is adapted to the outer peripheral contour of the adjusting pin at the adjusting protrusion, and there is a gap between the two. In this way, when the upper hinge mechanism is assembled, the adjusting connection assembly is always in a locked state. At this time, the adjusting pin at the adjusting protrusion extends upward from the adjusting through hole of the upper fan side hinge plate and protrudes above the upper fan side hinge plate. Since the outer peripheral contour of the adjusting pin at the adjusting protrusion is an arc surface without sharp contours, even if this part of the adjusting pin protrudes above the upper fan side hinge plate, it will not pose a safety hazard even if a worker bumps into it.

[0021] Furthermore, the outer peripheral surface of the lower shaft section is in surface contact with the wall of the connecting hole, which increases the friction between the lower shaft section and the upper fan-side fixed base, preventing the lower shaft section from rotating freely. The lower shaft section is only allowed to rotate in the connecting hole when an external force is applied to the adjusting pin, thus ensuring the stability of the adjusting connection assembly in the unlocked or locked state.

[0022] Furthermore, the outer diameter of the upper shaft section is larger than that of the lower shaft section. The adjusting pin has a stepped shaft portion at the connection between the upper and lower shaft sections. The top surface of the upper fan-side fixing base is provided with a friction-increasing protrusion located on the outer periphery of the connecting hole. The stepped shaft portion abuts against the friction-increasing protrusion, and the two are in surface contact, further increasing the friction between the upper fan-side fixing base and the adjusting pin. This ensures that the adjusting pin is only allowed to rotate when an external force is applied to it, thus more reliably guaranteeing the stability of the adjusting connection assembly in the unlocked or locked state.

[0023] Preferably, a rotating groove is provided on the top surface of the adjusting pin. The rotating groove can be a triangular groove, a square groove, or a hexagonal groove. By inserting a rotating tool that matches the rotating groove into the rotating groove, the adjusting pin can be easily rotated to switch the state of the adjusting connection component, so that the adjusting connection component is in an unlocked state or a locked state, making the operation of switching the state of the adjusting connection component simple and easy to implement.

[0024] Preferably, the adjusting pin is a one-piece metal component. This gives the adjusting pin good structural strength, which helps to improve the structural strength of the one-piece upper hinge mechanism.

[0025] This application also provides a door and window, including a fixed outer frame, a door and window sash that is openable and closable and installed in the fixed outer frame, an upper hinge mechanism, and a lower hinge mechanism; the inner periphery of the fixed outer frame is provided with a frame mounting groove, and the fixed outer frame is fixedly provided with first mounting arms on both sides of the frame mounting groove along its thickness direction; the door and window sash includes a sash frame and a sash panel installed in the sash frame, the top and bottom surfaces of the sash frame are provided with sash mounting grooves, and the sash frame is fixedly provided with second mounting arms on both sides of the sash mounting groove along its thickness direction;

[0026] The upper hinge mechanism is the upper hinge mechanism as described above;

[0027] The lower hinge mechanism includes a lower frame side connecting assembly, a lower fan side connecting assembly, and a lower rotating connecting assembly. The lower fan side connecting assembly includes a lower fan side hinge plate and a lower fan side fixed base. The lower fan side hinge plate of the lower fan side connecting assembly is connected to the lower frame side connecting assembly through the lower rotating connecting assembly. The lower hinge mechanism is an integrated structure that keeps the lower frame side connecting assembly, the lower rotating connecting assembly, and the lower fan side connecting assembly connected in sequence.

[0028] The upper hinge mechanism is assembled between the top of the fan frame and the fixed outer frame. The upper frame side connecting component is housed in the frame mounting groove at the upper corner of the fixed outer frame and is fixed to the fixed outer frame. The bottom of the upper fan side fixing base is housed in the fan mounting groove at the top of the fan frame and is fixed to the fan frame.

[0029] The lower hinge mechanism is assembled between the bottom of the fan frame and the fixed outer frame. The lower frame side connecting component is housed in the frame mounting groove at the lower corner of the fixed outer frame and is fixed to the fixed outer frame. The top of the lower fan side fixing base is housed in the fan mounting groove at the bottom of the fan frame and is fixed to the fan frame.

[0030] In the doors and windows involved in this application, both the upper and lower hinge mechanisms are integral structures, possessing good structural strength, which helps improve the overall stability of the door and window structure, making the doors and windows durable. Furthermore, by incorporating a fulcrum component and an adjusting connection component into the integral upper hinge mechanism, this application allows the upper frame-side connecting component of the upper hinge mechanism to tilt downwards when the door and window sash with the integral upper and lower hinge mechanisms fixed to it is installed on a fixed outer frame. This enables the upper frame-side connecting component to easily insert into the frame mounting groove at the upper corner of the fixed outer frame, simplifying and facilitating the installation of the door and window sash with the integral upper and lower hinge mechanisms fixed to it on the fixed outer frame.

[0031] Furthermore, one end of the fan mounting groove at the top of the fan frame is an upper hinge insertion port that allows the upper fan-side fixing base to slide in, and the upper fan-side fixing base is fixedly connected to the fan frame by a first locking member; one end of the fan mounting groove at the bottom of the fan frame is a lower hinge insertion port that allows the lower fan-side fixing base to slide in, and the lower fan-side fixing base is fixedly connected to the fan frame by a second locking member. This facilitates the installation and fixing of the upper hinge mechanism at the top of the fan frame and the lower hinge mechanism at the bottom of the fan frame.

[0032] This application provides another method for installing doors and windows as described above, comprising the following steps:

[0033] S1. Insert the lower fan side fixing base of the lower hinge mechanism into the fan mounting groove at the bottom of the fan frame, and fix the lower fan side fixing base to the fan frame so that the lower hinge mechanism is fixed at the bottom of the fan frame and the lower hinge mechanism is in the open state.

[0034] S2. Insert the upper fan side fixing base of the upper hinge mechanism into the fan mounting groove at the top of the fan frame, and fix the upper fan side fixing base to the fan frame so that the upper hinge mechanism is fixed at the top of the fan frame and the upper hinge mechanism is in the open state.

[0035] S3. Lift the door and window sash and tilt the end of the door and window sash away from the fixed outer frame downwards, and insert the lower frame side connecting component of the lower hinge mechanism into the frame mounting groove at the lower corner of the fixed outer frame;

[0036] S4. The adjusting connection component in the upper hinge mechanism is in the unlocked state, and the upper frame side connection component is tilted downward, so that the upper frame side connection component is lower than the first mounting arm on the upper side of the fixed outer frame.

[0037] S5. Insert the upper frame side connecting component of the upper hinge mechanism into the frame mounting groove at the upper corner of the fixed outer frame;

[0038] S6. When the adjusting connection component in the upper hinge mechanism is locked, the upper fan-side hinge plate is in a horizontal state, and the upper frame-side connection component is inserted into the frame mounting groove at the upper corner of the fixed outer frame.

[0039] S7. Fix the lower frame side connecting component of the lower hinge mechanism to the lower corner of the fixed outer frame, and fix the upper frame side connecting component of the upper hinge mechanism to the upper corner of the fixed outer frame.

[0040] As described above, the upper hinge mechanism, door and window and their installation method of the present invention have the following beneficial effects:

[0041] 1. The upper hinge mechanism involved in this application is an integrated structure with good structural strength. After it is installed between the fixed outer frame and the sash frame of the door and window, it can also improve the stability of the overall structure of the door and window, making the door and window durable.

[0042] 2. This application sets a fulcrum component and an adjusting connection component in the upper hinge mechanism of the integrated structure, so that when the upper hinge mechanism is installed in the fixed outer frame, the upper frame side connection component tilts downward as a whole. The upper frame side connection component can be easily inserted into the frame mounting groove at the upper corner of the fixed outer frame, making the installation of the door and window sash with the upper hinge mechanism of the integrated structure in the fixed outer frame simple and easy to implement.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed in this application.

[0123] This invention relates to the field of door and window technology, specifically to an upper hinge mechanism, a door or window equipped with the upper hinge mechanism, and a method for installing the door or window. The door or window can be an inward-opening window or an outward-opening window.

[0124] For ease of description, in the following embodiments, the directions are defined as follows: the height direction of the door and window is defined as the up-down direction, the width direction of the door and window is defined as the left-right direction, and the thickness direction of the door and window is defined as the front-back direction; the thickness direction of the door and window is also the indoor-outdoor direction, and the outdoor side direction is the front direction.

[0125] like Figure 1 , Figure 3 and Figure 4As shown, a typical door and window includes a fixed outer frame 10, a door / window sash 20 that is closable and mounted within the fixed outer frame 10, an upper hinge mechanism 30, and a lower hinge mechanism 40. The upper hinge mechanism 30 and the lower hinge mechanism 40 are respectively mounted at the upper left and lower left corners of the door / window sash 20; or, the upper hinge mechanism 30 and the lower hinge mechanism 40 are respectively mounted at the upper right and lower right corners of the door / window sash 20. The door / window sash 20 is rotatably mounted to the fixed outer frame 10 via the upper hinge mechanism 30 and the lower hinge mechanism 40, allowing the door / window sash 20 to open inwards or outwards relative to the fixed outer frame 10, achieving inward or outward opening. The following description uses an inward-opening window, with the upper hinge mechanism 30 mounted at the upper right corner of the door / window sash 20 and the lower hinge mechanism 40 mounted at the lower right corner of the door / window sash 20 as an example to illustrate the preferred structure of each part of the door / window.

[0126] like Figure 3 , Figure 4 and Figure 7 As shown, the fixed outer frame 10 is used to fix it in the window opening of the building. The fixed outer frame 10 includes an upper outer frame profile 13, a lower outer frame profile 14, a left outer frame profile 15, and a right outer frame profile 16. The upper outer frame profile 13, the lower outer frame profile 14, the left outer frame profile 15, and the right outer frame profile 16 are all aluminum alloy profiles. The upper outer frame profile 13 and the lower outer frame profile 14 are vertically opposite each other and extend horizontally. The left outer frame profile 15 and the right outer frame profile 16 are horizontally opposite each other and extend vertically. A frame mounting groove 11 is provided on the inner periphery of the fixed outer frame 10. The frame mounting groove 11 is a C-shaped groove. The fixed outer frame 10 is fixed with first mounting arms 12 on the front and rear sides of the frame mounting groove 11 along its thickness direction. The first mounting arms 12 are inverted L-shaped and extend in the same direction as the frame mounting groove 11. Thus, the lower surface of the upper frame profile 13 is provided with a left-right extending frame mounting groove 11 and a first mounting arm 12; the upper surface of the lower frame profile 14 is provided with a left-right extending frame mounting groove 11 and a first mounting arm 12; the right surface of the left frame profile 15 is provided with a vertically extending frame mounting groove 11 and a first mounting arm 12; and the left surface of the right frame profile 16 is provided with a vertically extending frame mounting groove 11 and a first mounting arm 12. Furthermore, the frame mounting groove 11 on the lower side of the upper frame profile 13, the frame mounting groove 11 on the right side of the left frame profile 15, the frame mounting groove 11 on the upper side of the lower frame profile 14, and the frame mounting groove 11 on the left side of the right frame profile 16 are aligned in the front-back direction and connected end-to-end. The first mounting arm 12 on the lower surface of the upper frame profile 13 serves as the first mounting arm 12 for fixing the upper side of the outer frame 10, and the first mounting arm 12 on the upper surface of the lower frame profile 14 serves as the first mounting arm 12 for fixing the lower side of the outer frame 10.

[0127] like Figure 3 and Figure 4As shown, the door / window sash 20 includes a sash frame 21 and a sash panel 22 installed within the sash frame 21. The sash panel 22 is a single-layer glass structure or a multi-layer glass structure. The sash frame 21 includes an upper sash frame profile 25, a lower sash frame profile 26, a left sash frame profile 27, and a right sash frame profile 28. The upper sash frame profile 25, the lower sash frame profile 26, the left sash frame profile 27, and the right sash frame profile 28 are all aluminum alloy profiles. The upper sash frame profile 25 and the lower sash frame profile 26 are vertically opposite each other and extend horizontally. The left sash frame profile 27 and the right sash frame profile 28 are horizontally opposite each other and extend vertically. A fan mounting groove 23 is provided around the outer periphery of the fan frame 21. The fan mounting groove 23 is a C-shaped groove. Second mounting arms 24 are fixed to the front and rear sides of the fan mounting groove 23 along the thickness direction of the fan frame 21. The second mounting arms 24 are inverted L-shaped, and their extension direction is consistent with the extension direction of the fan mounting groove 23. Thus, the upper surface of the upper profile 25 of the fan frame has a fan mounting groove 23 extending horizontally, the lower surface of the lower profile 26 of the fan frame has a fan mounting groove 23 extending horizontally, the left surface of the left profile 27 of the fan frame has a fan mounting groove 23 extending vertically, and the right surface of the right profile 28 of the fan frame has a fan mounting groove 23 extending vertically. Furthermore, the fan mounting grooves 23 on the upper side of the upper profile 25, the left side of the left profile 27, the lower side of the lower profile 26, and the right side of the right profile 28 are aligned in the front-to-back direction and connected end-to-end.

[0128] like Figure 3 , Figure 5 , Figure 8 and Figure 9 As shown, the upper hinge mechanism 30 includes an upper frame side connecting assembly 31 for fixing to the upper right corner of the fixed outer frame 10, an upper fan side connecting assembly 32 for fixing to the top of the fan frame 21, and an upper rotating connecting assembly 33. The upper fan side connecting assembly 32 includes an upper fan side hinge plate 34 and an upper fan side fixing base 35 connected to the lower left side of the upper fan side hinge plate 34. The right section of the upper fan side hinge plate 34 is connected to the upper frame side connecting assembly 31 through the upper rotating connecting assembly 33. The integrated structure of the upper hinge mechanism 30 means that the upper frame side connecting assembly 31, the upper rotating connecting assembly 33, and the upper fan side connecting assembly 32 are always connected in sequence.

[0129] like Figure 4 , Figure 6 and Figure 21As shown, the lower hinge mechanism 40 includes a lower frame side connecting assembly 41 for fixing to the lower right corner of the fixed outer frame 10, a lower fan side connecting assembly 42 for fixing to the bottom of the fan frame 21, and a lower rotating connecting assembly 43. The lower fan side connecting assembly 42 includes a lower fan side hinge plate 44 and a lower fan side fixing base 45 fixed to the lower left side of the lower fan side hinge plate 44. The right section of the lower fan side hinge plate 44 is connected to the lower frame side connecting assembly 41 through the lower rotating connecting assembly 43. The integrated structure of the lower hinge mechanism 40 means that the lower frame side connecting assembly 41, the lower rotating connecting assembly 43, and the lower fan side connecting assembly 42 are always connected in sequence.

[0130] During door and window assembly, the upper hinge mechanism 30 and the lower hinge mechanism 40 are first fixed to the top and bottom of the door / window sash 20, respectively; then, the upper hinge mechanism 30 and the lower hinge mechanism 40 are installed into the fixed outer frame 10. To facilitate the installation of the door / window sash 20, with its pre-fixed integrated upper hinge mechanism 30 and lower hinge mechanism 40, into the fixed outer frame 10, this application improves the structure of the integrated upper hinge mechanism 30. Specifically: as follows... Figures 8 to 14 As shown, the upper hinge mechanism 30 also includes a fulcrum assembly 36 and an adjusting connection assembly 37. The upper fan-side hinge plate 34 is mounted on the upper fan-side fixed base 35, which can swing up and down via the fulcrum assembly 36. The left end of the upper fan-side hinge plate 34, away from the upper frame-side connecting assembly 31, is connected to the upper fan-side fixed base 35 via the adjusting connection assembly 37. Thus, the upper fan-side fixed base 35 is located on the left side of the fulcrum assembly 36, while the upper rotation connecting assembly 33 and the upper frame-side connecting assembly 31 are both located on the right side of the fulcrum assembly 36. The adjusting connection assembly 37 has an unlocked state that allows the upper fan-side hinge plate 34 to swing up and down around the fulcrum assembly 36, and a locked state that restricts the upper fan-side hinge plate 34 from swinging up and down around the fulcrum assembly 36. When the adjusting connection assembly 37 is in the unlocked state, the upper fan-side hinge plate 34 can swing up and down around the fulcrum assembly 36, which allows the left end of the upper fan-side hinge plate 34 connected to the adjusting connection assembly 37 to swing upward, thereby causing the upper frame-side connecting assembly 31 connected to the right end of the upper fan-side hinge plate 34 to tilt downward. When the adjusting connection assembly 37 is in the locked state, the upper fan-side hinge plate 34 cannot swing up and down, and the upper fan-side hinge plate 34 is in a horizontal state, so the upper frame-side connecting assembly 31 no longer tilts.

[0131] Furthermore, this application also provides a method for installing a door or window, the door or window including a fixed outer frame 10 having the above-described structure, a door or window sash 20, an upper hinge mechanism 30, and a lower hinge mechanism 40. The method for installing the door or window includes the following steps.

[0132] Step S1, as follows Figure 22a and Figure 22bAs shown, the lower fan side fixing base 45 of the lower hinge mechanism 40 is installed into the fan mounting groove 23 at the bottom of the fan frame lower profile 26, and the lower fan side fixing base 45 is fixedly connected to the fan frame 21, so that the lower hinge mechanism 40 is first fixed at the right end of the bottom of the fan frame lower profile 26, and the lower hinge mechanism 40 is in the open state.

[0133] Step S2, as follows Figure 22c and Figure 22d As shown, the upper fan side fixing base 35 of the upper hinge mechanism 30 is installed into the fan mounting groove 23 on the top of the fan frame upper profile 25, and the upper fan side fixing base 35 is fixedly connected to the fan frame 21, so that the upper hinge mechanism 30 is first fixed at the right end of the top of the fan frame upper profile 25, and the upper hinge mechanism 30 is in the open state.

[0134] Step S3: The worker lifts the door / window sash 20 and inserts it into the fixed outer frame 10 from the rear side. During insertion, the lower frame side connecting component 41 of the lower hinge mechanism 40 is first inserted into the frame mounting groove 11 at the lower corner of the fixed outer frame 10. Due to the setting of the first mounting arm 12 on the top surface of the lower profile 14 of the outer frame, when the lower frame side connecting component 41 is inserted into the frame mounting groove 11 at the lower corner of the fixed outer frame 10, the side of the door / window sash 20 away from the fixed outer frame 10 (i.e., the rear side when open) will tilt downwards. Figure 22e As shown, this is to avoid collision between the lower frame side connecting assembly 41 and the first mounting arm 12 on the top surface of the lower frame profile 14.

[0135] Step S4: By unlocking the adjusting connection component 37 in the upper hinge mechanism 30, the upper fan-side hinge plate 34 can swing up and down around the fulcrum component 36, thereby causing the upper frame-side connection component 31 connected to the right end of the upper fan-side hinge plate 34 to tilt downwards. Figure 11 and Figure 12 As shown; at this time, the upper frame side connecting component 31 is lower than the first mounting arm 12 on the bottom surface of the outer frame upper profile 13.

[0136] Step S5: Due to the downward inclination of the upper frame side connecting component 31 and its lower position below the first mounting arm 12 on the bottom surface of the outer frame upper profile 13, the upper frame side connecting component 31 of the upper hinge mechanism 30 can be easily inserted into the frame mounting groove 11 at the upper corner of the fixed outer frame 10. The upper frame side connecting component 31 will not collide with the first mounting arm 12 on the bottom surface of the outer frame upper profile 13, making this step easy to perform.

[0137] Step S6: When the adjusting connection component 37 in the upper hinge mechanism 30 is locked, the upper fan side hinge plate 34 is in a horizontal state and cannot swing up and down. During the process of the adjusting connection component 37 switching from the unlocked state to the locked state, the left end of the upper fan side hinge plate 34 swings downward and the right end of the upper fan side hinge plate 34 swings upward, which causes the upper frame side connection component 31 connected to the right end of the upper fan side hinge plate 34 to move upward. Then the upper frame side connection component 31 is inserted into the frame mounting groove 11 at the upper corner of the fixed outer frame 10.

[0138] Step S7: Fix the lower frame side connecting component 41 of the lower hinge mechanism 40 to the lower corner of the fixed outer frame 10, and fix the upper frame side connecting component 31 of the upper hinge mechanism 30 to the upper corner of the fixed outer frame 10. Alternatively, in step S3, the lower frame side connecting component 41 can be inserted into the frame mounting groove 11 at the lower corner of the fixed outer frame 10 to fix the lower frame side connecting component 41 to the fixed outer frame 10, and then the upper frame side connecting component 31 of the upper hinge mechanism 30 can be inserted into the frame mounting groove 11 at the upper corner of the fixed outer frame 10.

[0139] After the doors and windows are assembled, the upper right corner of the doors and windows, such as Figure 3 and Figure 5 As shown, the upper hinge mechanism 30 is assembled between the top of the sash frame 21 and the fixed outer frame 10. The upper frame side connecting component 31 is accommodated in the frame mounting groove 11 at the upper right corner of the fixed outer frame 10 and is fixed to the fixed outer frame 10. The bottom of the upper sash side fixing base 35 is accommodated in the sash mounting groove 23 at the top of the sash frame upper profile 25 and is fixed to the sash frame upper profile 25. At the lower right corner of the door / window, as shown... Figure 4 and Figure 6 As shown, the lower hinge mechanism 40 is assembled between the bottom of the fan frame 21 and the fixed outer frame 10. The lower frame side connecting component 41 is housed in the frame mounting groove 11 at the lower right corner of the fixed outer frame 10 and is fixed to the fixed outer frame 10. The top of the lower fan side fixing base 45 is housed in the fan mounting groove 23 at the bottom of the lower profile 26 of the fan frame and is fixed to the fan frame 21.

[0140] Preferably, such as Figure 8 and Figure 21 As shown, the upper frame side connecting assembly 31 includes an L-shaped sheet metal part, and the lower frame side connecting assembly 41 includes an L-shaped die-cast part. For the upper frame side connecting assembly 31: as... Figure 3 and Figure 5 As shown, the horizontal section of the L-shaped sheet metal part is fixedly locked to the right end of the upper profile 13 of the outer frame with screws, and the vertical section of the L-shaped sheet metal part is fixedly locked to the upper end of the right profile 16 of the outer frame with screws. For the lower frame side connecting assembly 41: as shown... Figure 4 and Figure 6As shown, the horizontal section of the L-shaped die-cast part is fixedly locked to the right end of the lower profile 14 of the outer frame with screws, and the vertical section of the L-shaped die-cast part is fixedly locked to the lower end of the right profile 16 of the outer frame with screws. The upper sash side connecting assembly 32 rotates inward or outward relative to the upper frame side connecting assembly 31 by the upper rotating connecting assembly 33, and the lower sash side connecting assembly 42 rotates inward or outward relative to the lower frame side connecting assembly 41 by the lower rotating connecting assembly 43, so that the door and window sash 20 opens or closes inward relative to the fixed outer frame 10.

[0141] The upper hinge mechanism 30, the door and window equipped with the upper hinge mechanism 30, and the installation method of the door and window involved in this application have the following advantages.

[0142] 1. Both the upper hinge mechanism 30 and the lower hinge mechanism 40 are integral structures with good structural strength. After they are installed between the fixed outer frame 10 and the sash frame 21 of the door and window, the stability of the overall structure of the door and window can be improved, making the door and window durable and reducing the failure rate.

[0143] 2. Based on the integrated upper hinge mechanism 30 and lower hinge mechanism 40 configured in the door and window, during the assembly of the door and window, the integrated lower hinge mechanism 40 is first fixed to the bottom of the door and window sash 20, and the integrated upper hinge mechanism 30 is fixed to the top of the door and window sash 20. Then, the door and window sash 20 with the upper hinge mechanism 30 and lower hinge mechanism 40 fixed is installed into the fixed outer frame 10. In this application, a fulcrum component 36 and an adjusting connection component 37 are provided in the integrated upper hinge mechanism 30. When the door and window sash 20 with the upper hinge mechanism 30 and lower hinge mechanism 40 fixed is installed into the fixed outer frame 10, by keeping the adjusting connection component 37 in the unlocked state, the right end of the upper sash side hinge plate 34 connected to the upper frame side hinge plate is pressed down, causing the upper frame side connection component 31 to tilt downward as a whole, lower than the first mounting arm 12 on the bottom surface of the upper profile 13 of the outer frame. In this way, the upper frame side connecting component 31 can easily pass over the first mounting arm 12 on the upper side of the fixed outer frame 10, allowing it to be easily inserted into the frame mounting groove 11 at the upper right corner of the fixed outer frame 10 without colliding with the first mounting arm 12 on the upper side of the fixed outer frame 10. This makes the installation of the door / window sash 20, which has an integrated upper hinge mechanism 30 and a lower hinge mechanism 40, in the fixed outer frame 10 simple and easy. After the upper frame side connecting component 31 is inserted into the frame mounting groove 11 at the upper right corner of the fixed outer frame 10, the adjusting connecting component 37 is locked, and then the upper frame side connecting component 31 is fixed to the fixed outer frame 10. This completes the assembly of the upper hinge mechanism 30 in the door / window, realizing the installation of the door / window sash 20, which has an integrated upper hinge mechanism 30, in the fixed outer frame 10.

[0144] Furthermore, the structure of the fulcrum component 36 is preferably as follows: Figures 8 to 15,as well as Figure 18 and Figure 19 As shown, the fulcrum assembly 36 includes a vertically arranged fulcrum pin 361 and a fulcrum through hole 351 formed in the upper fan-side fixed base 35 and extending vertically. The upper end of the fulcrum pin 361 is fixed in the upper fan-side hinge plate 34. The fulcrum pin 361 is movably inserted into the fulcrum through hole 351. The diameter of the fulcrum through hole 351 is larger than the outer diameter of the fulcrum pin 361, allowing the fulcrum pin 361 to swing within the fulcrum through hole 351. Thus, when the adjusting connection assembly 37 is in the unlocked state, the upper fan-side hinge plate 34 can swing up and down around the fulcrum pin 361 through the cooperation of the fulcrum pin 361 and the fulcrum through hole 351, and during the swinging process, the fulcrum pin 361 is allowed to swing up and down within the fulcrum through hole 351.

[0145] Furthermore, such as Figures 8 to 15 ,as well as Figure 19 As shown, the fulcrum assembly 36 also includes a limiting groove 352 formed in the upper fan-side fixing base 35, the limiting groove 352 being connected to the bottom of the fulcrum through hole 351; the groove width of the limiting groove 352 is much larger than the hole diameter of the fulcrum through hole 351, that is, the groove wall of the limiting groove 352 is distributed radially along the fulcrum pin 361 on the periphery of the hole wall of the fulcrum through hole 351, thereby forming a limiting step portion 353 at the connection between the upper fan-side fixing base 35 and the fulcrum through hole 351 and the limiting groove 352; a limiting flange 362 is fixedly provided at the lower end of the fulcrum pin 361, the groove width of the limiting groove 352 should allow the limiting flange 362 to be movably accommodated in the limiting groove 352, and there is a large gap between the outer periphery of the limiting flange 362 and the groove wall of the limiting groove 352. During the up-and-down movement of the upper side hinge plate 34, the limiting flange 362 can abut against the bottom surface of the limiting step portion 353.

[0146] When the adjustment connection component 37 is in the unlocked state, such as Figure 12As shown, during the up-and-down swinging of the upper fan-side hinge plate 34 around the fulcrum pin 361, the upper fan-side hinge plate 34 drives the fulcrum pin 361 to sway up and down. At the same time, the limiting flange 362 sways up and down in the limiting groove 352. During this process, the limiting step portion 353 abuts against the upper side of the limiting flange 362 to limit the upward swing of the limiting flange 362, thus limiting the upward swing amplitude of the upper fan-side hinge plate 34; the upper fan-side fixed base 35 abuts against the lower side of the upper fan-side hinge plate 34 to limit the downward swing of the upper fan-side hinge plate 34, thus limiting the downward swing amplitude of the upper fan-side hinge plate 34. Thus, during the process of installing the door / window sash 20 with the upper hinge mechanism 30 fixed into the fixed outer frame 10, the vertical swing amplitude of the upper sash side hinge plate 34 is reliably limited to a reasonable range. This allows the upper frame side connecting component 31 to be easily inserted into the frame mounting groove 11 at the upper corner of the fixed outer frame 10, while preventing collisions between the upper sash side hinge plate 34 and the fixed outer frame 10 due to excessive swing amplitude. In addition, the limiting step portion 353 can also constrain the limiting flange 362 in the limiting groove 352, thereby preventing the fulcrum pin 361 from disengaging upward from the fulcrum through hole 351.

[0147] Preferably, the fulcrum pin 361 is a one-piece metal component with good structural strength. Furthermore, the fulcrum pin 361 is riveted to the upper hinge plate 34, ensuring reliable fixation between them. This effectively enhances the structural strength of the one-piece upper hinge mechanism 30, ensuring the opening and closing performance of the doors and windows.

[0148] Furthermore, the preferred structure of the adjusting connection component 37 is as follows: Figures 8 to 14 , Figures 16 to 20 As shown, the adjusting connection assembly 37 includes a vertically arranged adjusting pin 371, an adjusting through hole 341 extending vertically through the left end of the upper fan-side hinge plate 34, and a connecting hole 354 in the upper fan-side fixed base 35. The adjusting pin 371 includes an upper shaft section 372, a lower shaft section 373, and an adjusting protrusion 374 that radially protrudes from the outer peripheral surface of the upper end of the upper shaft section 372. The lower shaft section 373 is rotatably connected to the connecting hole 354. The adjusting through hole 341 includes a hole body section 342 and a hole limiting section 343 communicating with the right side of the hole body section 342. The upper shaft section 372 passes through the hole body section 342. The hole diameter of the hole body section 342 is larger than the outer diameter of the upper shaft section 372, allowing relative swinging between the upper fan-side hinge plate 34 and the adjusting pin 371. The contour of the hole limiting section 343 is adapted to the outer peripheral contour of the adjusting protrusion 374.

[0149] When the upper hinge plate 34 is in a horizontal position, such as Figure 10As shown, the adjusting protrusion 374 on the adjusting pin 371 is higher than the top surface of the upper hinge plate 34, allowing the adjusting pin 371 to rotate. When the upper hinge plate 34 is in a horizontal position, rotating the adjusting pin 371 allows the adjusting protrusion 374 to rotate to the side directly above the hole limiting portion 343. When rotating the adjusting pin 371 causes the adjusting protrusion 374 to rotate to the side directly above the hole limiting portion 343, as... Figure 11 and Figure 12 As shown, the adjusting protrusion 374 is circumferentially aligned with the hole limiting portion 343. At this time, the adjusting protrusion 374 can be accommodated in the hole limiting portion 343, which allows the left end of the upper fan-side hinge plate 34 to swing upward, and the adjusting connection assembly 37 is in the unlocked state; when the adjusting pin 371 is rotated to make the adjusting protrusion 374 rotate past the side directly above the hole limiting portion 343, as Figure 13 and Figure 14 As shown, the adjusting protrusion 374 is circumferentially offset from the hole limiting part 343. At this time, the adjusting protrusion 374, the upper sash side hinge plate 34, and the upper sash side fixed base 35 abut against each other from top to bottom. The upper sash side hinge plate 34 cannot swing up and down, and the adjusting connection assembly 37 is in a locked state. Alternatively, in other embodiments, when the adjusting connection assembly 37 is in a locked state, there is a very small gap between the adjusting protrusion 374 and the upper sash side hinge plate 34. In the adjusting connection assembly 37 involved in this application, the adjusting connection assembly 37 can be switched to an unlocked state or a locked state simply by rotating the adjusting pin 371, which is convenient for workers to operate and makes it more convenient to install the door and window sash 20 with the integrated upper hinge mechanism 30 in the fixed outer frame 10.

[0150] In this embodiment, as Figure 17 and Figure 20 As shown, the adjusting pin 371 has one adjusting protrusion 374, and the upper fan-side hinge plate 34 has one hole limiting part 343, which facilitates the manufacturing of the adjusting pin 371 and the processing of the adjusting through hole 341 in the upper fan-side hinge plate 34. Of course, in other embodiments, the adjusting pin 371 can have two adjusting protrusions 374, and the upper fan-side hinge plate 34 can have two on the left and right sides, or two in the front and back, depending on the actual needs.

[0151] Furthermore, such as Figure 20 As shown, the outer peripheral surface of the adjusting protrusion 374 is an arc surface, and the outer peripheral surface of the adjusting protrusion 374 and the outer peripheral surface of the upper shaft section 372 are connected by an arc surface transition; as shown Figure 17As shown, the contour of the adjusting through hole 341 is adapted to the outer peripheral contour of the adjusting pin 371 at the adjusting protrusion 374, and there is a gap between the two. Thus, when the upper hinge mechanism 30 is assembled, the adjusting connection assembly 37 is always in the locked state. At this time, the part of the adjusting pin 371 where the adjusting protrusion 374 is located extends upward from the adjusting through hole 341 of the upper fan side hinge plate 34; and the outer peripheral contour of the adjusting pin 371 at the adjusting protrusion 374 is an arc surface without a sharp contour. Therefore, even if this part of the adjusting pin 371 is exposed on the upper side of the upper fan side hinge plate 34, even if a worker bumps into it, there will be no safety hazard.

[0152] Preferably, such as Figure 20 As shown, a rotating groove 376 is provided on the top surface of the adjusting pin 371. The rotating groove 376 can be a triangular groove, a square groove, or a hexagonal groove. By inserting a rotating tool that matches the rotating groove 376 into the rotating groove 376, the adjusting pin 371 can be easily rotated to switch the state of the adjusting connection component 37, so that the adjusting connection component 37 is in an unlocked state or a locked state, making the operation of switching the state of the adjusting connection component 37 simple and easy to implement.

[0153] Furthermore, the rotation of the adjusting pin 371 should satisfy the following condition: it is allowed to rotate only when an external force is applied to the adjusting pin 371, and it is not allowed to rotate when no external force is applied to the adjusting pin 371. Therefore, this application increases the friction between the adjusting pin 371 and the upper fan-side fixed base 35 by the following two friction-enhancing methods.

[0154] Method 1 for increasing friction: Figure 14 and Figure 16 As shown, the outer peripheral surface of the lower shaft section 373 and the wall of the connecting hole 354 are in surface contact fit, which increases the friction between the lower shaft section 373 and the upper fan-side fixed base 35, so that the lower shaft section 373 cannot rotate freely. Only when an external force is applied to the adjusting pin 371 is the lower shaft section 373 allowed to rotate in the connecting hole 354, thus ensuring the stability of the adjusting connection assembly 37 in the unlocked or locked state.

[0155] Method 2 for increasing friction: Figure 14 and Figure 16 As shown, the outer diameter of the upper shaft section 372 is larger than the outer diameter of the lower shaft section 373, so that the adjusting pin 371 forms a shaft step portion 375 at the connection between the upper shaft section 372 and the lower shaft section 373. The top surface of the upper fan side fixing base 35 is provided with a friction-increasing protrusion 355 located on the outer periphery of the connecting hole 354. The shaft step portion 375 abuts against the friction-increasing protrusion 355, and the two are in surface contact, which increases the friction between the upper fan side fixing base 35 and the adjusting pin 371, so that the adjusting pin 371 is allowed to rotate only when an external force is applied to the adjusting pin 371, and more reliably ensures the stability of the adjusting connection assembly 37 in the unlocked or locked state.

[0156] In addition, the lower end of the adjusting pin 371 can be bulged, so that the adjusting pin 371 has an integrally formed thickened bulging head at the lower end of the lower shaft section 373. The bulging head abuts against the bottom surface of the upper fan side fixing base 35, preventing the adjusting pin 371 from disengaging from the connecting hole 354 of the upper fan side fixing base 35.

[0157] Preferably, the adjusting pin 371 is a one-piece metal component, which gives the adjusting pin 371 good structural strength, effectively improves the structural strength of the one-piece upper hinge mechanism 30, and ensures the opening and closing performance of the door and window.

[0158] Furthermore, such as Figure 22c and Figure 22d As shown, the right end of the sash mounting groove 23 at the top of the sash frame profile 25 is the upper hinge insertion port. The upper hinge insertion port allows the upper sash side fixing base 35 to slide to the left into the sash mounting groove 23 at the top of the sash frame profile 25. After the upper sash side fixing base 35 has slid into place to the left, the first locking member 50 is used to fix the upper sash side fixing base 35 to the sash frame profile 25, thereby fixing the upper sash side fixing base 35 to the right end of the top of the door / window sash 20. Figure 22a and Figure 22b As shown, the right end of the sash mounting groove 23 at the bottom of the sash frame profile 26 is the lower hinge insertion port. The lower hinge insertion port allows the lower sash side fixing base 45 to slide to the left into the sash mounting groove 23 at the bottom of the sash frame profile 26. After the lower sash side fixing base 45 has slid into place to the left, the second locking member 60 is used to fix the lower sash side fixing base 45 to the sash frame profile 26, thereby fixing the lower sash side fixing base 45 at the right end of the bottom of the door / window sash 20. This facilitates the installation and fixing of the upper hinge mechanism 30 at the top of the sash frame 21 and the lower hinge mechanism 40 at the bottom of the sash frame 21. Both the first locking member 50 and the second locking member 60 are locking screws.

[0159] Furthermore, such as Figure 8 and Figure 21As shown, both the upper fan-side fixing base 35 and the lower fan-side fixing base 45 include an adjusting seat 71, a connecting seat 72, and an adjusting bolt 73. The adjusting seat 71 is located on the left side of the connecting seat 72. The adjusting seat 71 and the connecting seat 72 are connected by the adjusting bolt 73. The adjusting bolt 73 extends straight along the extension direction of the fan mounting groove 23 at the top and bottom of the fan frame 21. The adjusting bolt 73 is rotatably supported in the adjusting seat 71 and threadedly connected to the left end of the connecting seat 72. For the upper hinge mechanism 30, the right section of the connecting seat 72 of the upper fan-side fixing base 35 is connected to the upper fan-side hinge plate 34 through the fulcrum assembly 36 and the adjusting connection assembly 37. The adjusting seat 71 of the upper fan-side fixing base 35 is fixed to the upper profile 25 of the fan frame by two front and rear first locking members 50. For the lower hinge mechanism 40, the right section of the connecting seat 72 of the lower sash side fixed base 45 is fixedly connected to the lower sash side hinge plate 44, and the adjusting seat 71 of the lower sash side fixed base 45 is fixed to the lower profile 26 of the sash frame by two front and rear second locking members 60; preferably, the connecting seat 72 of the lower sash side fixed base 45 and the lower sash side hinge plate 44 can be combined into one component. In this way, after the door and window are assembled, rotating the adjusting bolt 73 can drive the adjusting seat 71 to move relative to the connecting seat 72, and the adjusting seat 71 is fixed to the door and window sash 20, thereby driving the door and window sash 20 to move relative to the fixed outer frame 10, so as to fine adjust the gap between the door and window sash 20 and the fixed outer frame 10, so as to optimize the assembly relationship between the door and window sash 20 and the fixed outer frame 10.

[0160] Preferably, such as Figure 8 and Figure 21 As shown, the adjusting seat 71 and the connecting seat 72 are connected by a pre-assembly structure. During the transportation of doors and windows, the pre-assembly structure reliably maintains the adjusting bolt 73 in the pre-assembled state between the adjusting seat 71 and the connecting seat 72, preventing the adjusting seat 71 from accidentally falling off the connecting seat 72. This provides better conditions for the subsequent on-site assembly of doors and windows, facilitating their assembly and installation. The pre-assembly structure between the adjusting seat 71 and the connecting seat 72 is prior art; for details, please refer to the hinge for doors and windows disclosed in Chinese Utility Model Patent No. CN219974211U, and therefore will not be described further here.

[0161] Preferably, such as Figure 9 and Figure 21 As shown, limiting ribs 74 are provided on the front and rear sides of the bottom of the adjusting seat 71 and the front and rear sides of the connecting seat 72 along the thickness direction of the door / window sash 20. Figure 22c and Figure 22dAs shown, after the upper fan-side fixing base 35 is slid from the right end of the upper fan frame profile 25 into its fan mounting groove 23, a pair of second mounting arms 24 on the top surface of the upper fan frame profile 25 abut against the bottom of the adjusting seat 71 and the bottom of the connecting seat 72 of the upper fan-side fixing base 35. The limiting ribs 74 of the upper fan-side fixing base 35 are engaged within the pair of second mounting arms 24 on the top surface of the upper fan frame profile 25, restricting the upper fan-side fixing base 35 from shifting in the vertical and horizontal directions and in the front-back direction. This ensures that the upper fan-side fixing base 35 can only slide left and right along the extension direction of the fan mounting groove 23 at the top of the fan frame 21, making the installation of the upper fan-side fixing base 35 more convenient and ensuring the accuracy of the installation of the upper fan-side fixing base 35 in the fan mounting groove 23 at the top of the fan frame 21. Similarly, as Figure 22a and Figure 22b As shown, after the lower fan side fixing base 45 is slid from the right end of the lower fan frame profile 26 into its fan mounting groove 23, a pair of second mounting arms 24 on the bottom surface of the lower fan frame profile 26 abut against the top of the adjusting seat 71 and the top of the connecting seat 72 of the lower fan side fixing base 45 on the front and rear sides. The limiting ribs 74 of the lower fan side fixing base 45 are locked in the pair of second mounting arms 24 on the bottom surface of the lower fan frame profile 26, restricting the lower fan side fixing base 45 from shifting in the vertical and horizontal directions and the front and rear directions. This allows the lower fan side fixing base 45 to slide left and right along the extension direction of the fan mounting groove 23 at the bottom of the fan frame 21, which makes the installation of the lower fan side fixing base 45 more convenient and ensures the installation accuracy of the lower fan side fixing base 45 in the fan mounting groove 23 at the bottom of the fan frame 21.

[0162] In summary, the assembly process of doors and windows with the above structure is as follows.

[0163] First, such as Figure 22a and Figure 22b As shown, the lower fan-side fixing base 45 of the lower hinge mechanism 40 is slid from the right end of the bottom of the fan frame lower profile 26 into the fan mounting groove 23. After it is slid into place, the adjusting seat 71 of the lower fan-side fixing base 45 is fixedly connected to the fan frame lower profile 26 using two locking screws, thereby fixing the lower hinge mechanism 40 as a whole at the right end of the bottom of the fan frame lower profile 26; at the same time, the lower hinge mechanism 40 is in the open state.

[0164] Second, such as Figure 22c and Figure 22dAs shown, the upper fan-side fixing base 35 of the upper hinge mechanism 30 is slid from the right end of the top of the upper profile 25 of the fan frame into the fan mounting groove 23. After it is slid into place, the adjusting seat 71 of the upper fan-side fixing base 35 is fixedly connected to the upper profile 25 of the fan frame using two locking screws, thereby fixing the upper hinge mechanism 30 as a whole at the right end of the top of the upper profile 25 of the fan frame. At the same time, the upper hinge mechanism 30 is in the open state, and the adjusting pin 371 is rotated to make the adjusting connection assembly 37 in the unlocked state, that is, the adjusting protrusion 374 of the adjusting pin 371 is located directly above the hole limiting part 343 of the upper fan-side hinge plate 34.

[0165] Third, such as Figure 22e As shown, the worker lifts the door / window sash 20, first tilting one side of the door / window sash 20 downwards, and inserts the lower frame side connecting component 41 of the lower hinge mechanism 40 into the frame mounting groove 11 at the lower corner of the fixed outer frame 10; then, the right end of the upper sash side hinge plate 34 is swung downwards, causing the upper frame side connecting component 31 to tilt downwards, thereby easily inserting the upper frame side connecting component 31 of the upper hinge mechanism 30 into the frame mounting groove 11 at the upper corner of the fixed outer frame 10.

[0166] Fourth, first restore the horizontal state of the upper fan side hinge plate 34, and insert the upper frame side connecting component 31 into the frame mounting groove 11 at the upper corner of the fixed outer frame 10; then, rotate the adjusting pin 371 to lock the adjusting connecting component 37, that is, the adjusting protrusion 374 of the adjusting pin 371 rotates by an angle from directly above the hole limiting part 343 of the upper fan side hinge plate 34.

[0167] Fifth, fix the lower frame side connecting component 41 of the lower hinge mechanism 40 to the lower corner of the fixed outer frame 10, and fix the upper frame side connecting component 31 of the upper hinge mechanism 30 to the upper corner of the fixed outer frame 10.

[0168] Of course, in the second step above, before using two locking screws to fix the adjusting seat 71 of the upper fan side fixing base 35 to the upper profile 25 of the fan frame, as follows: Figure 23As shown, an anti-detachment component 80 can be fixed to the top of the upper profile 25 of the sash frame. The anti-detachment component 80 can be made of screws or bolts and is fixed in the sash mounting groove 23 on the right side of the upper sash side fixing base 35. After the anti-detachment component 80 is fixed, its head forms an anti-slip protrusion, which is also distributed in the sash mounting groove 23 on the right side of the upper sash side fixing base 35. Thus, when a malfunction occurs during the use of the door and window, such as when the locking screws used to fix the upper sash side fixing base 35 to the upper profile 25 of the sash frame completely loosen, the door and window sash 20 will move downward under the action of gravity. Especially when the door and window sash 20 is opened, the door and window sash 20 will move relative to the upper hinge mechanism 30, causing the upper sash side fixing base 35 of the upper hinge mechanism 30 to slide to the right from the sash mounting groove 23 at the top of the door and window sash 20. The anti-slip protrusion can... When the upper sash side fixing base 35 is blocked on the right side, the upper sash side fixing base 35 will inevitably come into contact with the anti-slip protrusion on its right side when it slides to the right from the sash mounting groove 23. The anti-slip protrusion effectively blocks the upper sash side fixing base 35, restricting the upper sash side fixing base 35 from sliding further out of the sash mounting groove 23. This prevents the upper sash side fixing base 35 from sliding out of the sash mounting groove 23 completely, thus preventing the upper hinge mechanism 30 from completely separating from the door and window sash 20, thereby preventing the door and window sash 20 from falling and playing the role of a fall-proof window.

[0169] Furthermore, when the locking screws used to fix the upper sash side fixing base 35 and the upper sash frame profile 25 are not loosened or not completely loosened, the upper sash side fixing base 35 and the upper sash frame profile 25 are still fixedly connected. At this time, the upper sash side fixing base 35 and the upper sash side hinge plate 34 do not contact the anti-slip protrusion, that is, the upper hinge mechanism 30 does not contact the anti-falling component 80. The vibration generated by the upper hinge mechanism 30 during the opening and closing of the door and window sash 20 will not be transmitted to the anti-slip protrusion, so that the anti-falling component 80 is not affected by the vibration generated by the upper hinge mechanism 30. This design effectively prevents the anti-falling component 80 from becoming loose relative to the upper profile 25 of the sash frame due to vibrations from the upper hinge mechanism 30. This ensures the reliability of the anti-falling component 80 in the upper profile 25 of the sash frame, and ultimately reliably ensures the blocking effect of the anti-slip protrusion of the anti-falling component 80 on the upper sash side fixing base 35 when the upper sash side fixing base 35 of the upper hinge mechanism 30 slips out of the sash mounting groove 23 of the upper profile 25 of the sash frame. This gives the door and window high load-bearing capacity at the upper hinge mechanism 30, and ultimately effectively improves the reliability of the anti-falling sash.

[0170] Preferably, in order to facilitate the screws or bolts constituting the anti-slip component 80 being screwed into the upper profile 25 of the fan frame from top to bottom, a tightening operation through hole can be opened in the upper fan side hinge plate 34 of the upper hinge mechanism 30, and the anti-slip protrusion is exposed from the tightening operation through hole, so as to facilitate the fixed installation of the anti-slip component 80.

[0171] In summary, this invention effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0172] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
