Description

Technical Field

[0001] The utility model relates to the technical field of aluminum alloy doors and windows, in particular to a high-load-resistant hinge structure for doors and windows. Background Art

[0002] Currently, if Figure 1 As shown, the openable doors and windows installed in the building mainly include a fixed outer frame 10 fixed in the building, a door and window sash 20 installed in the fixed outer frame 10 so as to be openable and closable, an upper hinge mechanism 30, and a lower hinge mechanism 40. The door and 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 and 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 and window sash 20.

[0003] The existing upper and lower hinge mechanisms can be of separate or integrated structures. Regardless of whether they are separate or integrated, when they are installed on the sash frame, they are first slid into (i.e., slidably installed) the C-shaped groove of the sash frame profile. Fastening screws are then screwed into the upper and lower hinge mechanisms, securing the upper hinge mechanism to the C-shaped groove at the top of the upper sash frame profile, and the lower hinge mechanism to the C-shaped groove at the bottom of the lower sash frame profile.

[0004] When doors and windows are opened and closed, both the upper and lower hinge mechanisms vibrate. This vibration is transmitted to the fastening screws securing the upper hinge mechanism to the sash frame, as well as the fastening screws securing the lower hinge mechanism to the sash frame, causing the fastening screws to loosen. When the fastening screws securing the upper hinge mechanism to the sash frame loosen, the upper hinge mechanism can easily slip out of the C-shaped groove at the top of the upper profile of the sash frame, causing the upper hinge mechanism to separate from the upper profile of the sash frame, which can easily cause the sash frame to fall.

[0005] In response to the above problems, the existing technology: the Chinese invention patent application with application publication number CN111997461A discloses an adjustable automatic locking hidden hinge, which strengthens the connection between the hinge and the window sash and window frame by adding a sash edge connector for connecting the window sash profile and a frame edge connector for connecting the window frame profile, thereby achieving the purpose of preventing the sash from falling. The sash edge connector disclosed therein mainly includes a first sash edge connector for connecting the sash connector and a second sash edge connector for buckling the window sash profile. The first sash edge connector and the second sash edge connector cooperate to buckle into an L-shaped structure. The first sash edge connector is provided with a waist-shaped hole. An eccentric rivet is riveted on the sash connector and passes through the waist-shaped hole. By twisting the eccentric rivet, the sash connector is pressed tightly into the horizontal mounting groove of the window sash profile. However, in the prior art, the sash edge connector components that reinforce the upper hinge and the window sash profile are numerous and have a complex structure; in particular, the sash edge connector and the hinge are in a connected state under normal conditions, specifically, the first sash edge connector in the sash edge connector and the sash connector in the hinge are fastened and fixed by screws. The vibration generated by the hinge during the opening and closing process of doors and windows will still be transmitted to the screws that lock the first sash edge connector and the sash connector in the hinge, which can easily cause the screws to loosen, resulting in poor anti-falling effect. Utility Model Content

[0006] In view of the above-mentioned shortcomings of the prior art, the technical problem to be solved by the present invention is to provide a high-load-resistant hinge structure for doors and windows, so as to effectively improve the reliability of the anti-falling fan.

[0007] To achieve the above-mentioned object, the utility model provides a high-load-resistant hinge structure for doors and windows, comprising a fixed outer frame, a door and window sash installed in the fixed outer frame so as to be openable and closable, and an upper hinge mechanism, the sash frame of the door and window sash comprising an upper sash frame profile, the upper hinge mechanism comprising a frame-side connecting assembly fixed to the fixed outer frame, and a sash-side connecting assembly fixed to the upper sash frame profile, the top of the upper sash frame profile being provided with a horizontally extending hinge mounting groove, one end of the hinge mounting groove being a hinge insertion opening, the sash-side connecting assembly sliding into the hinge mounting groove through the hinge insertion opening, and being fixedly connected to the upper sash frame profile by a locking member; the high-load-resistant hinge structure for doors and windows further comprising an anti-slip stopper fixed to the sash frame, the anti-slip stopper comprising a port blocking portion, the port blocking portion being located at the hinge insertion opening;

[0008] When the fan-side connection assembly is in a locked state fixed to the upper profile of the fan frame, the port blocking portion is not in contact with the fan-side connection assembly;

[0009] When the fan side connection assembly is in a slipping state from the hinge mounting groove of the upper profile of the fan frame, the port blocking portion can resist on one side of the fan side connection assembly along the slipping direction of the fan side connection assembly.

[0010] In the high-load-bearing hinge structure for doors and windows involved in this application, the upper hinge mechanism is assembled between the upper end of the door and window sash and the fixed outer frame. After the various components of the high-load-bearing hinge structure for doors and windows are assembled, the port blocking portion on the anti-drop stopper is located at the hinge insertion port. When the locking piece used to fix the sash side connection assembly and the upper profile of the sash frame is completely loosened, the door and window sash moves downward a certain amount under the action of gravity, and the door and window sash moves relative to the upper hinge mechanism, causing the sash side connection assembly of the upper hinge mechanism to slide out of the hinge mounting groove at the top of the door and window sash toward the hinge insertion port. The port blocking portion provided at the hinge insertion port can abut against the sash side connection assembly that has slipped to the hinge insertion port, and the port blocking portion of the anti-slip stopper effectively blocks the sash side connection assembly, limiting the sash side connection assembly from further sliding out of the hinge mounting groove, even if at least a part of the sash side connection assembly is retained in the hinge mounting groove, preventing the sash side connection assembly from sliding out of the hinge mounting groove completely, thereby preventing the upper hinge mechanism from being completely separated from the door and window sash, thereby preventing the door and window sash from falling, and playing the role of preventing windows from falling.

[0011] In particular, in the high-load-resistant hinge structure for doors and windows involved in the present application, under normal conditions, the locking piece used to fix the sash side connection assembly and the profile on the sash frame is not loose, or the locking piece is loose but not completely loose. At this time, the sash side connection assembly and the profile on the sash frame of the door and window sash are still in a fixed connection state, and no relative movement will occur between the sash side connection assembly and the profile on the sash frame of the door and window sash. The anti-slip stop is not affected by the vibration generated by the upper hinge mechanism, that is, the anti-slip stop is not affected by the force of the upper hinge mechanism, thereby strictly preventing the anti-slip stop from loosening relative to the sash frame of the door and window sash due to the vibration of the upper hinge mechanism, thereby ensuring the reliability of the anti-slip stop being fixed in the sash frame of the door and window sash, and finally reliably ensuring the resistance effect of the port blocking part of the anti-slip stop on the sash side connection assembly when the sash side connection assembly of the subsequent upper hinge mechanism slips out of the hinge mounting groove of the upper profile of the sash frame, so that the doors and windows have high load resistance characteristics at the upper hinge mechanism, and ultimately effectively improve the reliability of the anti-fall fan.

[0012] In addition, the present application only achieves the purpose of high load resistance at the upper hinge mechanism by adding an anti-slip stop fixed in the sash frame of the door and window sash. The number of additional components is only one anti-slip stop, which has a simple structure, low cost and is easy to implement.

[0013] Furthermore, the sash frame of the door and window sash further includes a sash frame longitudinal profile connected to one end of the sash frame upper profile on which the upper hinge mechanism is mounted, the outer circumferential surface of the sash frame longitudinal profile being provided with a stopper mounting groove, one end of the stopper mounting groove being a stopper insertion opening, the anti-slip stopper sliding into the stopper mounting groove through the stopper insertion opening and being fixedly connected to the sash frame longitudinal profile, the stopper mounting groove being in communication with the hinge insertion opening. This facilitates the fixed installation of the anti-slip stopper on the sash frame longitudinal profile, and facilitates the port blocking portion of the anti-slip stopper being located at the hinge insertion opening, thereby effectively preventing the sash-side connection assembly from slipping.

[0014] Preferably, the stopper mounting groove extends vertically, and the port blocking portion is provided at the upper end of the anti-drop stopper. Thus, after the anti-drop stopper slides into position along the stopper mounting groove, the port blocking portion at the upper end of the anti-drop stopper protrudes upward from the upper end of the stopper mounting groove, and the port blocking portion precisely blocks the hinge insertion port, thereby preventing the window from falling.

[0015] Furthermore, the formation structure of the stop member installation groove is: a pair of first installation arms are provided on the outer peripheral surface of the sash frame longitudinal profile, the pair of first installation arms extend straight along the length direction of the sash frame longitudinal profile, and are relatively arranged along the thickness direction of the sash frame longitudinal profile, the first installation arm is in an inverted L-shape, and a stop member installation groove is formed between the outer peripheral surface of the sash frame longitudinal profile and the inner surface of the pair of first installation arms, and the stop member installation groove is preferably a C-shaped groove; the anti-slip stop member includes a stop main plate portion, and a first limiting rib fixed on both sides of the stop main plate portion, and the first limiting rib is clamped in the first installation arm portion. In this way, after the anti-slip stop slides into the stop installation groove, a pair of first installation arms resist on both sides of the anti-slip stop, limiting the anti-slip stop from offsetting in the left and right directions and the thickness direction of the longitudinal profile of the sash frame, so that the anti-slip stop can only slide along the extension direction of the stop installation groove, which can not only make the installation of the anti-slip stop more convenient, but also ensure the installation accuracy of the anti-slip stop in the stop installation groove.

[0016] Preferably, the first limiting rib is integrally bent and extended from the stop main board portion, so that the anti-slip stopper forms a bent structure at the connection between the stop main board portion and the first limiting rib, which can enhance the structural strength of the anti-slip stopper itself, and make the port blocking portion of the anti-slip stopper have a better resistance effect to the fan side connection component in the slipping state, thereby better improving the reliability of the anti-fall fan.

[0017] Preferably, the anti-slip stopper is an aluminum profile with an integrated structure, which facilitates the production of the anti-slip stopper and also makes the anti-slip stopper itself have better structural strength, thereby improving its reliability in playing the role of preventing the fan from falling.

[0018] Furthermore, the upper end of the stop main plate is flush with the upper end of the first limiting rib, and the lower end of the stop main plate is flush with the lower end of the first limiting rib. That is, the extension length of the stop main plate is consistent with the extension length of the first limiting rib. Based on this, the upper end of the stop main plate and the upper end of the first limiting rib constitute the port blocking portion, so that the surface of the port blocking portion facing the hinge insertion port has a larger area. This allows the port blocking portion to better resist and stop the fan-side connecting assembly when it is in a slipping state, further improving the reliability of the anti-fall fan.

[0019] Furthermore, the stop main plate is fixedly connected to the sash frame longitudinal profile by rivets, screws or bolts, facilitating the fixed installation of the anti-drop stopper. Based on the fixing method of rivets, screws or bolts, the stop main plate is provided with a fixing hole allowing the rivets, screws or bolts to be inserted.

[0020] Furthermore, the lower end of the stopper main plate is lower than the lower end of the frame-side connecting assembly, and the fixed connection point between the stopper main plate and the sash frame longitudinal profile is located below the frame-side connecting assembly. Thus, when the stopper main plate is secured to the sash frame longitudinal profile using rivets, screws, or bolts, the upper hinge mechanism, which has been slidably inserted into the hinge mounting slot, is located above the fixing hole on the stopper main plate. This prevents the upper hinge mechanism from interfering with the securing operation when the stopper main plate is secured using rivets, screws, or bolts, further facilitating the securement and installation of the anti-slip stopper.

[0021] Furthermore, the sash-side connection assembly includes an adjustment seat fixedly connected to the sash frame upper profile via a locking member, a sash-side hinge plate connected to the frame-side connection assembly, and a connection seat connected between the adjustment seat and the sash-side hinge plate. The bottoms of the adjustment seat and the connection seat are both accommodated in the hinge mounting slot, and the sash-side hinge plate is located above the hinge mounting slot. When the sash-side connection assembly is in a locked state fixed to the sash frame upper profile, the port blocking portion is located below the sash-side hinge plate. The configuration of the adjustment seat in the sash-side connection assembly enables fine-tuning of the gap between the door and window sash and the fixed outer frame, optimizing the assembly relationship between the two.

[0022] Furthermore, a pair of second mounting arms are provided on the top surface of the sash frame upper profile. The pair of second mounting arms extend straight along the length direction of the sash frame upper profile and are arranged opposite to each other along the thickness direction of the sash frame upper profile. The second mounting arms are in an inverted L-shape. A hinge mounting groove is formed between the top surface of the sash frame upper profile and the inner surface of the pair of second mounting arms. Second limiting ribs are provided on both sides of the adjustment seat and the connecting seat along the thickness direction of the sash frame upper profile. The second limiting ribs are clamped in the second mounting arms. In this way, after the sash side connecting assembly slides into the hinge mounting groove, the pair of second mounting arms abut against both sides of the adjustment seat and the connecting seat, limiting the displacement of the sash side connecting assembly in the vertical direction and the thickness direction of the sash frame upper profile, so that the sash side connecting assembly can only slide along the extension direction of the hinge mounting groove. This not only makes the installation of the sash side connecting assembly more convenient, but also ensures the installation accuracy of the sash side connecting assembly in the hinge mounting groove.

[0023] As described above, the high load-bearing hinge structure for doors and windows of the present invention has the following beneficial effects:

[0024] When the door and window sash is in a state of being moved downward by gravity, the door and window sash will move relative to the upper hinge mechanism, causing the door and window sash to slide out of the hinge mounting groove at the top of the door and window sash toward the hinge insertion port. The port blocking portion provided at the hinge insertion port can abut against the door and window sash connecting assembly that has slipped to the hinge insertion port, and the port blocking portion of the anti-slip stopper will effectively resist the door and window sash connecting assembly, limiting the further slipping of the door and window sash connecting assembly from the hinge mounting groove. Even if at least a part of the door and window sash connecting assembly is retained in the hinge mounting groove, the door and window sash can be prevented from completely slipping out of the hinge mounting groove, thereby preventing the upper hinge mechanism from being completely separated from the door and window sash, thereby preventing the door and window sash from falling and playing the role of preventing the window from falling.

[0025] 2. In the normal state of the high-load-resistant hinge structure for doors and windows, the locking parts used to fix the sash side connection assembly and the upper profile of the sash frame are not loose, or the locking parts are loose but not completely loose. At this time, the sash side connection assembly and the upper profile of the sash frame of the door and window sash are still in a fixed connection state, and no relative movement will occur between the sash side connection assembly and the upper profile of the sash frame of the door and window sash. The anti-slip stop is not affected by the vibration generated by the upper hinge mechanism, that is, the anti-slip stop is not affected by the force of the upper hinge mechanism, thereby strictly preventing the anti-slip stop from loosening relative to the sash frame of the door and window sash due to the vibration of the upper hinge mechanism, thereby ensuring the reliability of the anti-slip stop being fixed in the sash frame of the door and window sash, and finally reliably ensuring the resistance effect of the port blocking part of the anti-slip stop on the sash side connection assembly when the sash side connection assembly of the subsequent upper hinge mechanism slips out of the hinge mounting groove of the upper profile of the sash frame, so that the doors and windows have high load resistance characteristics at the upper hinge mechanism, and ultimately effectively improve the reliability of the anti-fall fan.

[0026] 3. The purpose of high load resistance at the upper hinge mechanism is achieved by simply adding an anti-slip stopper fixed to the sash frame of the door and window sash. The number of additional components is only one anti-slip stopper, which has a simple structure, low cost and is easy to implement. BRIEF DESCRIPTION OF THE DRAWINGS

[0075] It should also be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or indirectly connected to the other element through an intervening element.

[0076] In addition, the descriptions of "first", "second", etc. in this application are for descriptive purposes only and should not be understood as indicating or implying their relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0077] The present invention relates to the technical field of doors and windows, and more particularly to a high-load-resistant hinge structure for doors and windows. Doors and windows equipped with the high-load-resistant hinge structure can be either inward-opening or outward-opening. For ease of description, in the following embodiments, the various 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, with the outdoor side direction being the front direction.

[0078] like Figure 1 As shown, a door or window typically includes a fixed outer frame 10, a door or window sash 20 that is openably mounted in the fixed outer frame 10, an upper hinge mechanism 30, and a lower hinge mechanism 40. The fixed outer frame 10 is fixed to a window opening in a building and includes an upper outer frame profile 11, a lower outer frame profile 12, a left outer frame profile 13, and a right outer frame profile 14. The upper outer frame profile 11, the lower outer frame profile 12, the left outer frame profile 13, and the right outer frame profile 14 are all aluminum alloy profiles. The upper outer frame profile 11 and the lower outer frame profile 12 are opposed to each other vertically and extend straight from side to side. The left outer frame profile 13 and the right outer frame profile 14 are opposed to each other horizontally and extend straight from side to side. Therefore, in the fixed outer frame 10, the upper outer frame profile 11 and the lower outer frame profile 12 are both horizontally extending horizontal profiles, while the left outer frame profile 13 and the right outer frame profile 14 are both vertically extending vertical profiles. The door and window sash 20 includes a sash frame 21 and a sash panel 22 installed in 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 profile 211, a lower sash profile 212, a left sash profile 213, and a right sash profile 214. The upper sash profile 211, the lower sash profile 212, the left sash profile 213, and the right sash profile 214 are all aluminum alloy profiles. The upper sash profile 211 and the lower sash profile 212 are opposite to each other in vertical direction and extend straight from left to right. The left sash profile 213 and the right sash profile 214 are opposite to each other in horizontal direction and extend straight from top to bottom. Therefore, in the sash frame 21, the upper sash profile 211 and the lower sash profile 212 are both horizontally extending horizontal profiles, and the left sash profile 213 and the right sash profile 214 are both vertically extending longitudinal profiles.

[0079] The upper hinge mechanism 30 and the lower hinge mechanism 40 are respectively mounted at the upper left corner and the lower left corner of the door and window sash 20; or, the upper hinge mechanism 30 and the lower hinge mechanism 40 are respectively mounted at the upper right corner and the lower right corner of the door and window sash 20. Figure 1 The following description will be made using the door and window as an example. The door and window are inward-opening windows. The upper hinge mechanism 30 in the door and window is assembled at the upper right corner of the door and window sash 20, and the lower hinge mechanism 40 in the door and window sash is assembled at the lower right corner of the door and window sash 20. The door and window sash 20 is rotatably mounted on the fixed outer frame 10 through the upper hinge mechanism 30 and the lower hinge mechanism 40, so that the door and window sash 20 can be opened inward relative to the fixed outer frame 10 to achieve inward opening. Figures 1 to 3 ,as well as Figure 7 and Figure 8 As shown, the upper hinge mechanism 30 includes a frame side connecting component 31, a sash side connecting component 32 and a rotating connecting component 33. The frame side connecting component 31 is fixedly connected to the outer frame upper profile 11 and the outer frame right profile 14 of the fixed outer frame 10. The sash side connecting component 32 is fixed at the right end of the sash frame upper profile 211 of the door and window sash 20. The rotating connecting component 33 is connected between the frame side connecting component 31 and the sash side connecting component 32. The sash side connecting component 32 rotates inward or outward relative to the frame side connecting component 31 through the rotating connecting component 33, thereby causing the door and window sash 20 to open or close inward relative to the fixed outer frame 10.

[0080] Preferably, if Figure 2 and Figure 3 ,as well as Figure 7 and Figure 8 As shown, the frame-side connecting assembly 31 is an L-shaped sheet metal component. The horizontal section of the L-shaped sheet metal component is screwed and locked to the right end of the outer frame upper profile 11, and the vertical section of the L-shaped sheet metal component is screwed and locked to the upper end of the outer frame right profile 14, thereby fixing the frame-side connecting assembly 31 to the upper right corner of the outer frame 10. The top surface of the sash frame upper profile 211 is provided with a hinge mounting slot 23 extending horizontally in the left-right direction. The hinge mounting slot 23 is a through-slot structure that runs from left to right, and the right end of the hinge mounting slot 23 is a hinge insertion opening 24. When installing the sash-side connecting assembly 32, it slides leftward into the hinge mounting groove 23 through the hinge insertion opening 24 at the right end of the hinge mounting groove 23. After the sash-side connecting assembly 32 is slid leftward into place in the hinge mounting groove 23, the locking member 50 is used to securely connect the sash-side connecting assembly 32 to the sash frame upper profile 211, thereby securing the sash-side connecting assembly 32 to the right end of the top of the door and window sash 20. In this way, the upper hinge mechanism 30 is assembled between the upper end of the door and window sash 20 and the fixed outer frame 10, allowing the door and window sash 20 to rotate inward relative to the fixed outer frame 10.

[0081] like Figures 2 to 5As shown, the high-load-resistant hinge structure for doors and windows involved in the utility model includes, in addition to the fixed outer frame 10, the door and window sash 20, and the upper hinge mechanism 30 of the above-mentioned doors and windows, an anti-slip stopper 60 fixed to the sash frame 21. The anti-slip stopper 60 includes a port blocking portion 61, which is located at the hinge insertion port 24. When the sash-side connecting assembly 32 is in a locked state fixed to the sash frame upper profile 211, the port blocking portion 61 does not contact the sash-side connecting assembly 32; when the sash-side connecting assembly 32 is in a sliding state of sliding rightward from the hinge mounting groove 23 of the sash frame upper profile 211, the port blocking portion 61 can resist the right side of the sash-side connecting assembly 32 along the sliding direction of the sash-side connecting assembly 32.

[0082] In the aforementioned high-load-bearing hinge structure for doors and windows, when the upper hinge mechanism 30 is secured to the top of the sash frame upper profile 211 of the door and window sash 20, the anti-slip stopper 60 is not secured to the sash frame 21. The port blocking portion 61 of the anti-slip stopper 60 is not located at the hinge insertion opening 24, thereby preventing interference with the secure installation of the sash-side connecting assembly 32 of the upper hinge mechanism 30 to the top of the sash frame upper profile 211. After the sash-side connecting assembly 32 of the upper hinge mechanism 30 is secured to the top of the sash frame upper profile 211, the anti-slip stopper 60 is installed in place. Once the anti-slip stopper 60 is in place, it is securely connected to the sash frame 21, with the port blocking portion 61 of the anti-slip stopper 60 located at the hinge insertion opening 24. This position, along with the port blocking portion 61 of the anti-slip stopper 60, means that the port blocking portion 61 of the anti-slip stopper 60 is located to the right of the sash-side connecting assembly 32, and the port blocking portion 61 does not contact the sash-side connecting assembly 32.

[0083] When the door and window fails and the locking piece 50 for fixing the sash side connection assembly 32 and the upper profile 211 of the sash frame is completely loosened, the door and window sash 20 moves downward to a certain extent under the action of gravity, and the door and window sash 20 moves relative to the upper hinge mechanism 30, causing the sash side connection assembly 32 of the upper hinge mechanism 30 to slide to the right from the hinge mounting groove 23 at the top of the door and window sash 20 toward the hinge insertion port 24; and the port blocking portion 61 is arranged on the right side of the sash side connection assembly 32 along the sliding direction of the sash side connection assembly 32, then when the sash side connection assembly 32 slides to the right to the hinge insertion port 24, the sash side connection assembly 32 abuts against the port blocking portion 61 at the hinge insertion port 24, that is, the port blocking portion 61 abuts on the right side of the sash side connection assembly 32 along the sliding direction of the sash side connection assembly 32, and the port blocking portion 61 effectively blocks the sash side connection assembly 32. In this way, the port blocking portion 61 limits the sash side connecting component 32 from sliding further to the right from the hinge mounting groove 23, that is, even if at least a portion of the sash side connecting component 32 is retained in the hinge mounting groove 23, it prevents the sash side connecting component 32 from sliding out of the hinge mounting groove 23 completely, thereby preventing the upper hinge mechanism 30 from being completely separated from the door and window sash 20, thereby preventing the door and window sash 20 from falling, and playing the role of preventing the window from falling.

[0084] In particular, in the high-load-resistant hinge structure for doors and windows involved in the present application, under normal circumstances, the locking piece 50 used to fix the sash side connection component 32 and the sash frame upper profile 211 is not loose, or the locking piece 50 is loose but not completely loose. At this time, the sash side connection component 32 is always in a locked state fixed to the top of the sash frame upper profile 211, that is, the sash side connection component 32 and the sash frame upper profile 211 of the door and window sash 20 are always in a fixed connection state, and no relative movement will occur between the sash side connection component 32 and the sash frame upper profile 211 of the door and window sash 20. In this state, the port blocking portion 61 is always out of contact with the fan-side connecting assembly 32, or in other words, the anti-dropping stopper 60 is not in contact with the upper hinge mechanism 30. Therefore, the vibration generated by the upper hinge mechanism 30 during the opening and closing process of the door and window fan 20 will not be transmitted to the port blocking portion 61, nor will it be transmitted to the anti-dropping stopper 60, so that the anti-dropping stopper 60 is not affected by the vibration generated by the upper hinge mechanism 30, that is, the anti-dropping stopper 60 is not affected by the force of the upper hinge mechanism 30, thereby strictly avoiding the anti-dropping stopper 60 from being affected by the vibration generated by the upper hinge mechanism 30. The vibration of the hinge mechanism 30 causes it to become loose relative to the sash frame 21 of the door and window sash 20, thereby ensuring the reliability of the anti-slip stop 60 being fixed in the sash frame 21 of the door and window sash 20, and ultimately reliably ensuring the resistance effect of the port blocking portion 61 of the anti-slip stop 60 on the sash side connection component 32 when the sash side connection component 32 of the subsequent upper hinge mechanism 30 slips out of the hinge mounting groove 23 of the sash frame upper profile 211, so that the doors and windows have high load-bearing characteristics at the upper hinge mechanism 30, and ultimately effectively improve the reliability of the anti-falling sash.

[0085] In addition, the present application only achieves the purpose of high load resistance at the upper hinge mechanism 30 by adding an anti-slip stop 60 fixed in the fan frame 21. The number of additional components is only one anti-slip stop 60, which has a simple structure, low cost and is easy to implement.

[0086] Furthermore, if Figures 2 to 6 As shown, the sash frame 21 of the door and window sash 20 also includes a sash frame longitudinal profile 25, which is connected to the right end of the sash frame upper profile 211 where the upper hinge mechanism 30 is installed. In this embodiment, the sash frame longitudinal profile 25 is the sash frame right profile 214, and the anti-slip stopper 60 is fixed to the sash frame longitudinal profile 25. Preferably, a stopper mounting groove 251 is provided on the right surface of the right profile 214 of the sash frame, and the stopper mounting groove 251 is connected to the hinge insertion port 24; one end of the stopper mounting groove 251 is the stopper insertion port 252, and the anti-slip stopper 60 slides into the stopper mounting groove 251 through the stopper insertion port 252. By sliding the anti-slip stopper 60 in the stopper mounting groove 251, the port blocking portion 61 can slide to the hinge insertion port 24 or move away from the hinge insertion port 24, so that the installation of the upper hinge mechanism 30 and the anti-slip stopper 60 on the sash frame 21 is more flexible.

[0087] For example: the anti-slip stopper 60 can be slid into the stopper mounting groove 251 through the stopper insertion port 252 first, but the anti-slip stopper 60 is not fixed, so that the port blocking portion 61 is moved away from the hinge insertion port 24; then the fan side connecting assembly 32 of the upper hinge mechanism 30 is slid into the hinge mounting groove 23 through the hinge insertion port 24, and after sliding into place, the fan side connecting assembly 32 is fixed to the top of the fan frame upper profile 211 using the locking member 50; finally, the anti-slip stopper 60 is slid into place in the stopper mounting groove 251, and the anti-slip stopper 60 is fixed to the right side of the fan frame longitudinal profile 25. For example, first, the sash-side connecting assembly 32 of the upper hinge mechanism 30 is slid into the hinge installation slot 23 through the hinge insertion opening 24. Once fully engaged, the locking member 50 is used to secure the sash-side connecting assembly 32 to the top of the sash frame upper profile 211. The anti-slip stopper 60 is then slid into the stopper installation slot 251 through the stopper insertion opening 252. Once fully engaged, the anti-slip stopper 60 is secured to the right side of the sash frame longitudinal profile 25. This allows for more flexible installation of the upper hinge mechanism 30 and the anti-slip stopper 60. In addition, the setting of the stopper mounting groove 251 also facilitates the fixed installation of the anti-slip stopper 60 on the longitudinal profile 25 of the sash frame, and the sliding of the anti-slip stopper 60 in the stopper mounting groove 251 can more easily make the port blocking portion 61 of the anti-slip stopper 60 slide to the hinge insertion port 24, thereby blocking the hinge insertion port 24 and effectively playing the role of resisting and stopping the sash side connection component 32 in the slipping state.

[0088] Furthermore, the stopper mounting groove 251 on the right sash frame profile 214 can extend vertically in the up-down direction, horizontally in the front-back direction, or obliquely. Figures 3 to 6 As shown, the stopper mounting slot 251 extends vertically, forming a through-slot structure. The port blocking portion 61 is located at the upper end of the anti-dropout stopper 60. The stopper mounting slot 251 is perpendicular to and communicates with the hinge mounting slot 23. In the front-to-back direction, the stopper mounting slot 251 is aligned with the hinge mounting slot 23, and the width of the stopper mounting slot 251 is equal to the width of the hinge mounting slot 23. Based on this limitation, when installing the upper hinge mechanism 30 and the anti-slip stop 60 on the sash frame 21, first slide the anti-slip stop 60 downward into the stop installation groove 251 through the stop insertion port 252. Since the upper hinge mechanism 30 has not yet been fixed to the top of the sash frame 21 at this time and there is no obstruction above the sash frame 21, it is very convenient to insert the anti-slip stop 60 downward into the stop installation groove 251. Afterwards, slide the anti-slip stop 60 downward along the stop installation groove 251 until the anti-slip stop 60 is completely located in the stop installation groove 251, and the port blocking portion 61 does not emerge upward from the upper end of the stop installation groove 251. Block the hinge insertion port 24 at the right end of the hinge mounting slot 23; then, slide the fan-side connecting assembly 32 of the upper hinge mechanism 30 into the hinge mounting slot 23 through the hinge insertion port 24, and use the locking member 50 to fix the fan-side connecting assembly 32 to the top of the fan frame upper profile 211 after sliding into place; then, slide the anti-slip stopper 60 upward along the stopper mounting slot 251 into place, and the port blocking portion 61 will emerge upward from the upper end of the stopper mounting slot 251 and block the hinge insertion port 24 at the right end of the hinge mounting slot 23, thereby playing its role in preventing the window from falling; finally, fix the anti-slip stopper 60 to the fan frame longitudinal profile 25. Therefore, the stopper insertion opening 252 is the upper end opening of the stopper mounting groove 251, and the anti-slip stopper 60 is first inserted into the stopper mounting groove 251 before the fan side connecting assembly 32 of the upper hinge mechanism 30 is fixed to the top of the fan frame 21. There is a large operating space above the stopper mounting groove 251, which facilitates the installation of the anti-slip stopper 60 in the fan frame longitudinal profile 25.

[0089] Furthermore, the stopper installation groove 251 on the right side of the sash frame longitudinal profile 25 is a C-shaped groove, and the formation structure of the stopper installation groove 251 of the C-shaped groove structure is as follows: Figures 3 to 6 As shown, a pair of first mounting arms 253 are provided on the outer peripheral surface of the sash frame longitudinal profile 25, and the pair of first mounting arms 253 extend straight up and down along the length direction of the sash frame longitudinal profile 25. The pair of first mounting arms 253 are arranged relatively front to back along the thickness direction of the sash frame longitudinal profile 25, and the first mounting arms 253 are in an inverted L shape. A stopper mounting groove 251 is formed between the outer peripheral surface of the sash frame longitudinal profile 25 and the inner surface of the pair of first mounting arms 253.

[0090] Furthermore, the preferred structure of the anti-slip stopper 60 is as follows: Figures 3 to 5 ,as well as Figure 8 As shown, the anti-slip stopper 60 includes a stopper main plate portion 62 and first limiting ribs 63 fixedly provided on the front and rear sides of the stopper main plate portion 62. The stopper main plate portion 62 is a longitudinal flat plate structure extending vertically. The first limiting ribs 63 are clamped in the first mounting arms 253. Thus, after the anti-slip stopper 60 slides into the stopper mounting slot 251, the pair of first mounting arms 253 abut against the front and rear sides of the anti-slip stopper 60, limiting the displacement of the anti-slip stopper 60 in the left-right and front-back directions, so that the anti-slip stopper 60 can only slide upward along the extension direction of the stopper mounting slot 251. This not only makes the installation of the anti-slip stopper 60 more convenient, but also ensures the installation accuracy of the anti-slip stopper 60 in the stopper mounting slot 251.

[0091] Preferably, the anti-slip stopper 60 is an aluminum profile with an integrated structure, which facilitates the production of the anti-slip stopper 60. Figure 8 As shown, the first limiting rib 63 is integrally bent and extended from the stop main plate portion 62, forming a bent structure at the junction of the stop main plate portion 62 and the first limiting rib 63. Combined with the integrated structure of the anti-slip stop 60, the anti-slip stop 60 itself has better structural strength, so that the port blocking portion 61 of the anti-slip stop 60 has a better resistance effect against the fan-side connecting assembly 32 in a slipping state, further improving the reliability of the anti-fall fan.

[0092] Preferably, if Figure 5 、 Figure 6 and Figure 8 As shown, along the vertically extending length of the anti-slip stopper 60, the length of the stopper main plate 62, and the length of the first position-limiting rib 63 are consistent; that is, the upper end of the stopper main plate 62 is flush with the upper end of the first position-limiting rib 63, and the lower end of the stopper main plate 62 is flush with the lower end of the first position-limiting rib 63. With this arrangement, the upper end of the stopper main plate 62 and the upper ends of the first position-limiting ribs 63 on its front and rear sides together form the port blocking portion 61. This allows the left surface of the port blocking portion 61 facing the hinge insertion opening 24 to have a larger area. This allows the port blocking portion 61 to better resist and stop the fan-side connecting assembly 32 when it is in a slipping state, further improving the reliability of the anti-fall fan.

[0093] Preferably, the stopper main plate portion 62 is fixedly connected to the fan frame longitudinal profile 25 by fasteners, which can be rivets 70 or screws or bolts to facilitate the fixed installation of the anti-drop stopper 60. In this embodiment, Figure 3 and Figure 4As shown, the stopper main plate portion 62 is fixedly connected to the sash frame longitudinal profile 25 by rivets 70. In addition, based on the fixing method between the stopper main plate portion 62 and the sash frame longitudinal profile 25 by rivets 70, screws or bolts, the stopper main plate portion 62 is provided with a fixing hole 64 allowing the rivet 70, screw or bolt to be inserted.

[0094] Furthermore, if Figure 3 and Figure 4 As shown, the lower end of the stopper main plate portion 62 is lower than the lower end of the frame-side connecting assembly 31 in the upper hinge mechanism 30. The fixed connection point between the stopper main plate portion 62 and the sash frame longitudinal profile 25 is located below the frame-side connecting assembly 31. That is, the fixing holes 64 on the stopper main plate portion 62 are located below the frame-side connecting assembly 31. In this way, when the stopper main plate portion 62 is fixed to the sash frame longitudinal profile 25 using rivets 70, screws, or bolts, the upper hinge mechanism 30, which has been slidably inserted into the hinge mounting slot 23, is located entirely above the fixing holes 64 on the stopper main plate portion 62. When the stopper main plate portion 62 is subsequently fixed using rivets 70, screws, or bolts, the upper hinge mechanism 30 will not interfere with the fixing operation, further facilitating the fixed installation of the anti-slip stopper 60.

[0095] Furthermore, the hinge mounting groove 23 on the top of the sash frame profile 211 is also a C-shaped groove. The formation structure of the hinge mounting groove 23 of the C-shaped groove structure is as follows: Figure 2 、 Figure 3 and Figure 6 As shown, a pair of second mounting arms 26 are provided on the top surface of the sash frame upper profile 211. The pair of second mounting arms 26 extend straight left and right along the length direction of the sash frame upper profile 211. The pair of second mounting arms 26 are arranged front and back oppositely along the thickness direction of the sash frame upper profile 211. The second mounting arms 26 are in an inverted L-shape. A hinge mounting groove 23 with a C-shaped groove structure is formed between the top surface of the sash frame upper profile 211 and the inner surface of the pair of second mounting arms 26. In addition, after the anti-slip stopper 60 is fixedly installed on the right side of the sash frame longitudinal profile 25, as shown in FIG. Figure 5 and Figure 6 As shown, the portion of the first limiting rib 63 constituting the port blocking portion 61 abuts against the right end side of the second mounting arm 26 , and the upper end of the first limiting rib 63 is flush with the upper end of the second mounting arm 26 .

[0096] Furthermore, the preferred structure of the fan-side connecting assembly 32 in the upper hinge mechanism 30 is as follows: Figure 7 and Figure 8As shown, the fan-side connection assembly 32 includes an adjustment seat 321, a connection seat 323, and a fan-side hinge plate 322. The adjustment seat 321 is located on the left side of the connection seat 323. The adjustment seat 321 and the connection seat 323 are connected by an adjustment bolt 325 that extends straight along the extension direction of the hinge mounting slot 23. The adjustment bolt 325 is rotatably supported in the adjustment seat 321 and threaded into the left end of the connection seat 323. The connection seat 323 is a sheet metal component. The right end of the connection seat 323 is fixedly connected to the left end of the fan-side hinge plate 322. The fan-side hinge plate 322 is connected to the frame-side connection assembly 31 via the rotation connection assembly 33. When installing the sash-side connecting assembly 32 on top of the sash frame upper profile 211, first slide the adjustment seat 321 and the connecting seat 323 to the left, successively, into the hinge mounting slot 23. Once fully engaged, secure the adjustment seat 321 to the sash frame upper profile 211 using the locking member 50, which is a locking screw, with two locking screws provided, one in front and one in the back. After the door and window are assembled, rotating the adjusting bolt 325 causes the adjustment seat 321 to move relative to the connecting seat 323 and the sash-side hinge plate 322. The adjustment seat 321 is secured to the door and window sash 20, thereby causing the door and window sash 20 to move relative to the fixed outer frame 10, thereby fine-tuning the gap between the door and window sash 20 and the fixed outer frame 10 and optimizing the assembly relationship between the door and window sash 20 and the fixed outer frame 10.

[0097] Preferably, if Figure 7 and Figure 8 As shown, the adjustment seat 321 and the connecting seat 323 are connected by a pre-assembled structure 326. During the transportation of the doors and windows, the pre-assembled structure 326 ensures that the adjustment bolt 325 is securely maintained in the pre-assembled state between the adjustment seat 321 and the connecting seat 323, thereby preventing the adjustment seat 321 from accidentally falling off the connecting seat 323 during this process. This provides better conditions for subsequent on-site assembly of the doors and windows, facilitating subsequent on-site assembly and installation of the doors and windows. The pre-assembled structure 326 between the adjustment seat 321 and the connecting seat 323 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 in detail here.

[0098] Furthermore, after the fan-side connecting assembly 32 of the upper hinge mechanism 30 is fixed to the top of the fan frame upper profile 211, as shown in FIG. Figure 2 and Figure 3As shown, the bottom of the adjustment seat 321 and the bottom of the connecting seat 323 are both accommodated in the hinge mounting groove 23, so that the adjustment seat 321 and the connecting seat 323 are both away from the port blocking portion 61 of the anti-slip stop 60. The sash-side hinge plate 322 is located above the hinge mounting groove 23, that is, higher than the second mounting arm 26, so that the sash-side hinge plate 322 is also away from the port blocking portion 61 of the anti-slip stop 60. In this way, when the door or window is in a normal state, the adjustment seat 321, the connecting seat 323, and the sash-side hinge plate 322 will not contact the port blocking portion 61 at the top of the anti-slip stop 60, thereby preventing vibration generated by the upper hinge mechanism 30 from being transmitted to the anti-slip stop 60. When an accident occurs to the door or window, after the locking piece 50 is completely loosened, the adjusting seat 321 and the connecting seat 323 slide to the right from the hinge mounting groove 23. When the right end of the connecting seat 323 slides to the right to the port blocking portion 61, the right end of the connecting seat 323 abuts against the left end of the port blocking portion 61. The fixed port blocking portion 61 forms a stop for the rightward sliding of the connecting seat 323, restricting the connecting seat 323 there, preventing the connecting seat 323 from sliding out of the hinge mounting groove 23, thereby preventing the fan side connecting assembly 32 from completely disengaging from the door and window fan 20, and reliably preventing the door and window fan 20 from falling out of the window.

[0099] Furthermore, if Figure 2 and Figure 3 ,as well as Figure 7 and Figure 8 As shown, along the thickness direction of the sash frame upper profile 211, second limiting ribs 324 are provided on the front and rear sides of the bottom of the adjustment seat 321 and the front and rear sides of the bottom of the connecting seat 323. The second limiting ribs 324 are clamped in the second mounting arm 26. In this way, after the adjustment seat 321 and the connecting seat 323 of the sash-side connecting assembly 32 slide leftward into the hinge mounting groove 23, the pair of second mounting arms 26 abut on the front and rear sides of the adjustment seat 321 and the connecting seat 323, limiting the displacement of the sash-side connecting assembly 32 in the up-down direction and the front-back direction, so that the sash-side connecting assembly 32 can only slide left and right along the extension direction of the hinge mounting groove 23. This not only makes the installation of the sash-side connecting assembly 32 more convenient, but also ensures the installation accuracy of the sash-side connecting assembly 32 in the hinge mounting groove 23.

[0100] In summary, the high load-bearing hinge structure for doors and windows involved in this application has the following advantages.

[0101] 1. By simply adding an aluminum alloy plate constituting an anti-slip stopper 60 to the outer peripheral side of the sash frame longitudinal profile 25, when the sash-side connecting assembly 32 of the upper hinge mechanism 30 accidentally slips out of the hinge mounting groove 23, the anti-slip stopper 60 can stop the sash-side connecting assembly 32 from slipping out, so that the upper hinge mechanism 30 does not separate from the door and window sash 20, thereby playing the role of preventing the window from falling. The structure is simple and the cost is low.

[0102] 2. When the doors and windows are in normal condition, the fan-side connecting assembly 32 of the upper hinge mechanism 30 is not in contact with the anti-slip stop 60, and the vibration of the upper hinge mechanism 30 will not be transmitted to the anti-slip stop 60. The anti-slip stop 60 is not easy to loosen, which effectively improves its stopping effect on the fan-side connecting assembly 32 in the slipping state, thereby effectively improving the reliability of the anti-fall fan.

[0103] In summary, the present invention effectively overcomes various shortcomings of the prior art and has high industrial utilization value.

[0104] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may 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 one of ordinary skill in the art without departing from the spirit and technical principles disclosed in the present invention are intended to be covered by the claims of the present invention.
