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, wherein the door and window sash comprises an upper profile of the sash frame, the upper hinge mechanism comprises a frame-side connecting assembly fixed to the fixed outer frame, and a sash-side connecting assembly fixed to the upper profile of the sash frame, the top of the upper profile of the sash frame is provided with a mounting groove allowing the sash-side connecting assembly to slide in, the sash-side connecting assembly and the upper profile of the sash frame being fixedly connected by a locking member; the high-load-resistant hinge structure for doors and windows also comprises an anti-falling component fixed to the upper profile of the sash frame, the anti-falling component has an anti-slip protrusion located in the mounting groove, the anti-slip protrusion being provided on a slipping path of the sash-side connecting assembly slipping out of the mounting groove;

[0008] When the fan-side connecting assembly is in a locked state fixed to the upper profile of the fan frame, the anti-slip protrusion is not in contact with the fan-side connecting assembly;

[0009] When the fan side connection assembly is in a slipping state of slipping out of the installation groove of the profile on the fan frame, the anti-slip protrusion 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 disclosed herein, an upper hinge mechanism is assembled between the upper end of the door or window sash and a fixed outer frame. Before the sash-side connecting assembly of the upper hinge mechanism is slid into the mounting groove at the top of the upper profile of the door or window sash frame, the anti-drop component is temporarily not fixed to the upper profile of the sash frame. After the fan side connecting assembly of the upper hinge mechanism is slid into the installation groove from the end of the installation groove, the anti-falling component can be fixedly installed on the upper profile of the fan frame first, and then the fan side connecting assembly of the upper hinge mechanism can be slid into place in the installation groove, and finally the fan side connecting assembly can be fixedly connected to the upper profile of the fan frame using a locking piece, thereby fixing the upper hinge mechanism to the top of the upper profile of the fan frame, completing the fixed installation of the upper hinge mechanism on the upper profile of the fan frame, thereby first completing the fixation of the anti-falling component and then completing the fixation of the fan side connecting assembly of the upper hinge mechanism; or, the fan side connecting assembly of the upper hinge mechanism can be slid into place in the installation groove first, and then the fan side connecting assembly can be fixedly connected to the upper profile of the fan frame using a locking piece, and finally the anti-falling component can be fixedly installed on the upper profile of the fan frame, thereby first completing the fixation of the fan side connecting assembly of the upper hinge mechanism and then completing the fixation of the anti-falling component.

[0011] In the high-load-bearing hinge structure for doors and windows involved in the present application, after the anti-slip component and the sash side connection assembly are fixedly installed on the sash frame upper profile, the anti-slip protrusion on the anti-slip component is located in the installation groove, the anti-slip protrusion does not contact the sash side connection assembly, and is distributed on one side of the sash side connection assembly along the sliding direction of the sash side connection assembly from the installation groove. After such arrangement, when the locking member used to fix the sash side connection assembly to the sash frame upper profile is not loose, or the locking member is loose but not completely loosened, the sash side connection assembly and the sash frame upper profile are still fixedly connected, and the sash side connection assembly is in a locked state. In this state, the anti-slip protrusion does not contact the sash side connection assembly, so the vibration generated by the upper hinge mechanism during the opening and closing process of the door and window sash will not be transmitted to the anti-slip protrusion, so that the anti-slip component is not affected by the vibration generated by the upper hinge mechanism, that is, the anti-slip component is not affected by the force of the upper hinge mechanism, thereby preventing the anti-slip component from loosening.

[0012] 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 will move downward a certain amount under the action of gravity, and the door and window sash will produce relative movement with respect to the upper hinge mechanism, causing the sash side connection assembly of the upper hinge mechanism to slip out of the mounting groove at the top of the door and window sash, and the anti-slip protrusion can be abutted on one side of the sash side connection assembly along the sliding direction of the sash side connection assembly. When the sash side connection assembly slips out of the mounting groove, it is bound to abut against the anti-slip protrusion. The anti-slip protrusion effectively resists the sash side connection assembly, limiting the sash side connection assembly from further slipping out of the mounting groove, even if at least a part of the sash side connection assembly is retained in the mounting groove, preventing the sash side connection assembly from slipping out of the 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 falling windows.

[0013] In particular, the high load-bearing hinge structure for doors and windows involved in the present application is in a locked state under normal conditions, and the anti-slip protrusion is in a non-contact state with the sash-side connection assembly. In this way, under normal conditions, the vibration of the upper hinge mechanism will not be transmitted to the anti-slip component, thereby strictly preventing the anti-slip component from loosening relative to the upper profile of the sash frame due to the vibration of the upper hinge mechanism, thus ensuring the reliability of the anti-slip component being fixed in the upper profile of the sash frame, and ultimately reliably ensuring the anti-slip protrusion of the anti-slip component's resistance to the sash-side connection assembly when the sash-side connection assembly of the subsequent upper hinge mechanism slips from the mounting groove of the upper profile of the sash frame, so that the doors and windows have high load-bearing characteristics at the upper hinge mechanism, and ultimately effectively improving the reliability of the anti-fall fan.

[0014] In addition, this application only achieves the purpose of high load resistance at the upper hinge mechanism by adding an anti-falling component fixed on the top of the door and window sash. The number of additional components is only one anti-falling component, which has a simple structure, low cost and is easy to implement.

[0015] Furthermore, the anti-slip component can be a screw or a bolt, the head of the screw or the head of the bolt forming an anti-slip protrusion, and the upper profile of the sash frame is provided with a fixing threaded hole that is tightly engaged with the anti-slip component. This facilitates the fixing of the anti-slip component to the upper profile of the sash frame and reduces the cost of the anti-slip component, as it can be directly purchased with ready-made screws or bolts.

[0016] Preferably, the anti-falling component is in a vertical state extending up and down. When the screws or bolts constituting the anti-falling component are fixed in the upper profile of the sash frame, the anti-falling component is screwed into the fixed threaded hole of the upper profile of the sash frame from top to bottom. At this time, there is a large operating space above the upper profile of the sash frame, making the operation of screwing the anti-falling component into the upper profile of the sash frame simple and easy to implement.

[0017] Furthermore, in order to facilitate the operation of screwing the anti-falling component into the fixing threaded hole of the upper profile of the sash frame from top to bottom, a tightening operation through hole is provided in the sash-side connection assembly, and both the anti-slip protrusion and the fixing threaded hole can be exposed from the tightening operation through hole. With this arrangement, after the sash-side connection assembly slides into the installation groove at the top of the upper profile of the sash frame of the door and window sash, the fixing threaded hole at the top of the upper profile of the sash frame is exposed from the tightening operation through hole by sliding the sash-side connection assembly, that is, the tightening operation through hole is directly opposite to the fixing threaded hole. At this time, the worker can easily place the anti-falling component from the tightening operation through hole into the fixing threaded hole at the top of the upper profile of the sash frame, and screw the anti-falling component into the fixing threaded hole from top to bottom, making the fixing and installation of the anti-falling component at the top of the upper profile of the sash frame easier.

[0018] Furthermore, the anti-falling component is a metal part, and the anti-falling component itself has good structural strength. When the fan side connecting assembly accidentally slips out of the installation groove of the profile on the fan frame, the anti-slip protrusion of the anti-falling component has a better resistance effect on the fan side connecting assembly, thereby better improving the reliability of the anti-falling fan.

[0019] Furthermore, the sash side connection assembly includes an adjustment seat fixedly connected to the sash frame upper profile by 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 bottom of the adjustment seat and the bottom of the connection seat are both accommodated in the installation groove, and the sash side hinge plate is located on the upper side of the installation groove. When the sash side connection assembly is in a locked state fixed to the sash frame upper profile, the anti-slip protrusion is distributed on the lower side of the sash side hinge plate and the side of the connection seat facing away from the adjustment seat. When the sash side connection assembly is in a slipping state of slipping out of the installation groove of the sash frame upper profile, the anti-slip protrusion can abut against the connection seat. By configuring the adjustment seat, the sash side connection assembly can fine-tune the gap between the door and window sash and the fixed outer frame, thereby optimizing the assembly relationship between the two.

[0020] Furthermore, a pair of mounting arms is provided on the top surface of the sash frame upper profile, the pair of mounting arms extending straight along the length direction of the sash frame upper profile and arranged opposite to each other along the thickness direction of the sash frame upper profile, the mounting arms being in an inverted L-shape, a mounting groove being formed between the top surface of the sash frame upper profile and the inner surfaces of the pair of mounting arms, the mounting groove being preferably a C-shaped groove; limiting ribs are provided on both sides of the adjustment seat and both sides of the connecting seat along the thickness direction of the sash frame upper profile, the limiting ribs being clamped in the mounting arms. In this way, after the sash-side connecting assembly slides into the mounting groove, the pair of 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 mounting groove, which 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 mounting groove.

[0021] As described above, the high load-bearing hinge structure for doors and windows of the present invention has the following beneficial effects:

[0022] When the door and window sash are 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 mounting groove at the top of the door and window sash. The anti-slip protrusion can abut on one side of the door and window sash along the sliding direction of the door and window sash. When the door and window sash slide out of the mounting groove, the door and window sash will inevitably abut against the anti-slip protrusion. The anti-slip protrusion effectively blocks the door and window sash from further sliding out of the mounting groove. Even if at least a part of the door and window sash is retained in the mounting groove, the door and window sash can be prevented from completely sliding out of the 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 falling windows.

[0023] 2. Under normal circumstances, the fan side connection assembly is always in a locked state, and there is no contact between the anti-slip protrusion and the fan side connection assembly. The vibration of the upper hinge mechanism will not be transmitted to the anti-fall component, thereby strictly preventing the anti-fall component from loosening relative to the upper profile of the fan frame due to the vibration of the upper hinge mechanism, and thus ensuring the reliability of the anti-fall component being fixed in the upper profile of the fan frame. Ultimately, it reliably ensures that when the fan side connection assembly of the subsequent upper hinge mechanism slips from the mounting groove of the upper profile of the fan frame, the anti-slip protrusion of the anti-fall component has a resisting effect on the fan side connection assembly, 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.

[0024] 3. The purpose of high load resistance at the upper hinge mechanism is achieved by simply adding an anti-falling component fixed on the top of the door and window sash. The number of additional components is only one anti-falling component, which has a simple structure, low cost and is easy to implement. BRIEF DESCRIPTION OF THE DRAWINGS

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.

[0066] 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.

[0067] like Figure 1 As shown, a door or window generally includes a fixed outer frame 10, a door or window sash 20 openably and closably 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 in a window opening of a building and includes an outer frame upper profile 11, an outer frame lower profile 12, an outer frame left profile 13, and an outer frame right profile 14. The outer frame upper profile 11, the outer frame lower profile 12, the outer frame left profile 13, and the outer frame right profile 14 are all aluminum alloy profiles. The outer frame upper profile 11 and the outer frame lower profile 12 are opposite to each other in vertical direction and extend straight from left to right. The outer frame left profile 13 and the outer frame right profile 14 are opposite to each other in horizontal direction and extend straight from top to bottom. The door and window sash 20 includes a sash frame 21 and a sash panel 22 installed in the sash frame 21, and 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 211, a lower sash frame profile 212, a left sash frame profile 213 and a right sash frame profile 214, and the upper sash frame profile 211, the lower sash frame profile 212, the left sash frame profile 213 and the right sash frame profile 214 are all aluminum alloy profiles, the upper sash frame profile 211 and the lower sash frame profile 212 are opposite to each other up and down, and both extend straight left and right, the left sash frame profile 213 and the right sash frame profile 214 are opposite to each other left and right, and both extend straight up and down.

[0068] 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 6 and Figure 7As 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 fixedly connected to 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 accordingly.

[0069] Preferably, if Figure 2 and Figure 3 ,as well as Figure 6 and Figure 7 As shown, the frame-side connecting assembly 31 is an L-shaped sheet metal part. The horizontal section of the L-shaped sheet metal part is fixed and locked to the right end of the outer frame upper profile 11 by screws, and the vertical section of the L-shaped sheet metal part is fixed and locked to the upper end of the outer frame right profile 14 by screws, thereby fixing the frame-side connecting assembly 31 to the upper right corner of the fixed outer frame 10. The top surface of the sash frame upper profile 211 is provided with a mounting groove 23 extending straightly to the left and right. The mounting groove 23 is a through-groove structure that runs through the left and right. When the sash-side connecting assembly 32 is installed, the sash-side connecting assembly 32 slides into the mounting groove 23 from the notch at the right end of the mounting groove 23. After the sash-side connecting assembly 32 slides to the left into place in the mounting groove 23, the locking member 50 is used to fix the sash-side connecting assembly 32 to the sash frame upper profile 211, thereby fixing the sash-side connecting assembly 32 to the right end of the top of the door and window sash 20. In this manner, the upper hinge mechanism 30 is assembled between the upper end of the door / window sash 20 and the fixed outer frame 10 , allowing the door / window sash 20 to rotate inwardly relative to the fixed outer frame 10 .

[0070] like Figures 2 to 4 As 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, door and window sash 20 and upper hinge mechanism 30 in the above-mentioned doors and windows, an anti-falling component 60. The anti-falling component 60 is fixed to the sash frame upper profile 211 of the door and window sash 20. The anti-falling component 60 has an anti-slip protrusion 61 located in the mounting groove 23; and the anti-slip protrusion 61 is arranged on the slipping path of the sash side connecting component 32 from the mounting groove 23, that is, the anti-slip protrusion 61 is arranged in the part of the mounting groove 23 on the right side of the sash side connecting component 32. When the fan side connection component 32 is in a locked state fixed with the fan frame upper profile 211, the anti-slip protrusion 61 does not contact the fan side connection component 32; when the fan side connection component 32 is in a slipping state of sliding to the right from the installation groove 23 of the fan frame upper profile 211, the anti-slip protrusion 61 can resist the right side of the fan side connection component 32 along the slipping direction of the fan side connection component 32.

[0071] In the above-mentioned high-load-resistant hinge structure for doors and windows, before the sash-side connecting assembly 32 of the upper hinge mechanism 30 is slid into the mounting groove 23 at the top of the sash frame upper profile 211 of the door and window sash 20, the anti-fall-off component 60 is temporarily not fixedly installed on the sash frame upper profile 211.

[0072] The fan side connection component 32 of the upper hinge mechanism 30 and the anti-falling component 60 are fixed on the fan frame upper profile 211 as follows: first, slide the fan side connection component 32 of the upper hinge mechanism 30 from the right end of the installation groove 23 to the left into the installation groove 23, and temporarily do not install the locking member 50; then, fix the anti-falling component 60 on the fan frame upper profile 211; finally, slide the fan side connection component 32 of the upper hinge mechanism 30 into place in the installation groove 23, and then use the locking member 50 to fix the fan side connection component 32 to the fan frame upper profile 211, thereby fixing the upper hinge mechanism 30 to the top of the fan frame upper profile 211, completing the fixed installation of the upper hinge mechanism 30 on the top of the fan frame upper profile 211; that is: first complete the fixation of the anti-falling component 60, and then complete the fixation of the fan side connection component 32 of the upper hinge mechanism 30.

[0073] The fan side connection component 32 of the upper hinge mechanism 30 and the anti-falling component 60 can also be fixed on the fan frame upper profile 211 as follows: first, slide the fan side connection component 32 of the upper hinge mechanism 30 from the right end of the installation groove 23 to the left into the installation groove 23. After sliding into place, use the locking member 50 to fix the fan side connection component 32 to the fan frame upper profile 211, thereby fixing the upper hinge mechanism 30 to the top of the fan frame upper profile 211, completing the fixed installation of the upper hinge mechanism 30 on the top of the fan frame upper profile 211; thereafter, fix the anti-falling component 60 on the fan frame upper profile 211.

[0074] In the above two fixing methods, when the fan side connecting component 32 and the anti-falling component 60 of the upper hinge mechanism 30 are installed on the upper profile 211 of the fan frame, since the anti-falling component 60 is installed after the fan side connecting component 32 of the upper hinge mechanism 30 slides into the installation groove 23, the anti-falling component 60 will not interfere with the fixed installation of the upper hinge mechanism 30 on the upper profile 211 of the fan frame.

[0075] After the anti-falling component 60 and the fan side connecting component 32 of the upper hinge mechanism 30 are fixedly installed on the top of the fan frame upper profile 211, the anti-slip protrusion 61 on the anti-falling component 60 is located in the installation groove 23, but the anti-slip protrusion 61 does not contact the fan side connecting component 32, and is distributed on the right side of the fan side connecting component 32 along the sliding direction of the fan side connecting component 32 from the installation groove 23 to the right. After such arrangement, when the locking piece 50 for fixing the sash side connection assembly 32 and the sash frame upper profile 211 is not loose, or the locking piece 50 is loose but not completely loosened, the sash side connection assembly 32 and the sash frame upper profile 211 are still fixedly connected. At this time, the sash side connection assembly 32 is in a locked state fixed to the top of the sash frame upper profile 211. In this state, the anti-slip protrusion 61 is not in contact with the sash side connection assembly 32. Therefore, the vibration generated by the upper hinge mechanism 30 during the opening and closing process of the door and window sash 20 will not be transmitted to the anti-slip protrusion 61, so that the anti-falling component 60 is not affected by the vibration generated by the upper hinge mechanism 30, that is, the anti-falling component 60 is not affected by the force of the upper hinge mechanism 30, thereby preventing the anti-falling component 60 from loosening.

[0076] When the door and window occurs a fault that the locking piece 50 for fixing the sash side connection assembly 32 and the sash frame upper profile 211 is completely loosened, the door and window sash 20 will move downward to a certain extent under the action of gravity. In particular, 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 sash side connection assembly 32 of the upper hinge mechanism 30 to slide to the right from the mounting groove 23 at the top of the door and window sash 20, and the anti-slip protrusion 61 can resist 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 connecting component 32 slips out of the mounting groove 23, it is bound to abut against the anti-slip protrusion 61 on its right side. The anti-slip protrusion 61 effectively blocks the sash side connecting component 32, limiting the sash side connecting component 32 from further slipping out of the mounting groove 23. Even if at least a part of the sash side connecting component 32 is retained in the mounting groove 23, the sash side connecting component 32 is prevented from completely slipping out of the mounting groove 23, 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, thereby playing the role of preventing the window from falling.

[0077] In particular, in the high load-bearing hinge structure for doors and windows involved in the present application, under normal conditions, the sash-side connection assembly 32 is always in a locked state, and the anti-slip protrusion 61 is always in a non-contact state with the sash-side connection assembly 32. In this way, under normal conditions, the vibration of the upper hinge mechanism 30 will not be transmitted to the anti-falling component 60, thereby strictly preventing the anti-falling component 60 from loosening relative to the sash frame upper profile 211 due to the vibration of the upper hinge mechanism 30, thus ensuring the reliability of the anti-falling component 60 being fixed in the sash frame upper profile 211, and ultimately reliably ensuring the anti-slip protrusion 61 of the anti-falling component 60 to resist the sash-side connection assembly 32 when the sash-side connection assembly 32 of the subsequent upper hinge mechanism 30 slips from the 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 fan.

[0078] In addition, the present application only achieves the purpose of high load resistance at the upper hinge mechanism 30 by adding an anti-falling component 60 fixed on the top of the door and window sash 20. The number of additional components is only one anti-falling component 60, which has a simple structure, low cost and is easy to implement.

[0079] Furthermore, if Figure 4 and Figure 5 As shown, the anti-slip component 60 can be a screw or a bolt, with the head of the screw or the head of the bolt forming an anti-slip protrusion 61. The sash frame upper profile 211 is provided with a fixing threaded hole 24 that is tightly engaged with the anti-slip component 60. This facilitates the fixing of the anti-slip component 60 in the sash frame upper profile 211 and allows the anti-slip component 60 to be obtained by directly purchasing ready-made screws or bolts, thereby reducing the cost of the anti-slip component 60. In this embodiment, the anti-slip component 60 is a screw.

[0080] Preferably, the anti-falling component 60 is a metal component, that is, the anti-falling component 60 is a metal screw. In this way, the anti-falling component 60 itself has good structural strength and is securely fixed to the fan frame upper profile 211. When the fan-side connecting assembly 32 accidentally slips to the right from the mounting groove 23 of the fan frame upper profile 211, the anti-slip protrusion 61 of the anti-falling component 60 has a better resistance effect on the fan-side connecting assembly 32, thereby further improving the reliability of the anti-falling fan.

[0081] Preferably, the anti-falling component 60 can be fixed vertically on the top of the sash frame upper profile 211, can also be fixed horizontally on the top of the sash frame upper profile 211, can also be fixed obliquely on the top of the sash frame upper profile 211, just need to make its screw head located in the installation slot 23. Preferably, in this embodiment, as Figure 4 and Figure 5As shown, the anti-dropping component 60 is vertically fixed to the top of the sash frame upper profile 211, that is, the anti-dropping component 60 is in a vertical state extending up and down, and the fixing threaded hole 24 that is threadedly locked with the anti-dropping component 60 extends downward from the bottom of the mounting groove 23. In this way, when the screw constituting the anti-dropping component 60 is fixed to the sash frame upper profile 211, the anti-dropping component 60 is screwed into the fixing threaded hole 24 of the sash frame upper profile 211 from the upper side of the sash frame upper profile 211 from top to bottom. Since there is a large operating space above the sash frame upper profile 211, the operation of screwing the anti-dropping component 60 into the sash frame upper profile 211 is simple and easy to implement.

[0082] Furthermore, in order to facilitate the operation of screwing the anti-falling component 60 into the fixing threaded hole 24 of the upper profile 211 of the fan frame from top to bottom, as shown in FIG. Figure 3 and Figure 6 As shown, a tightening operation through hole 321 that passes through from top to bottom is provided in the fan side connection component 32; when the fan side connection component 32 of the upper hinge mechanism 30 slides into the installation groove 23, the tightening operation through hole 321 can be made to face the fixing threaded hole 24 at the top of the fan frame upper profile 211. At this time, the fixing threaded hole 24 at the top of the fan frame upper profile 211 is exposed from the tightening operation through hole 321; thereafter, the worker can easily put the anti-falling component 60 into the fixing threaded hole 24 at the top of the fan frame upper profile 211 from the tightening operation through hole 321, and screw the anti-falling component 60 into the fixing threaded hole 24 from top to bottom, so that the fixing installation of the anti-falling component 60 on the top of the fan frame upper profile 211 becomes easier. After the anti-drop component 60 is tightened, the screw head of the anti-slip protrusion 61 at the top of the anti-drop component 60 can be exposed from the tightening operation through hole 321. This also facilitates the anti-drop component 60 to be screwed out first when the fan-side connecting assembly 32 is subsequently detached, thereby avoiding interference with the detachment operation of the fan-side connecting assembly 32 from the top of the fan frame upper profile 211. Therefore, the provision of the tightening operation through hole 321 in the fan-side connecting assembly 32 facilitates both tightening and fixing the anti-drop component 60 to the top of the fan frame upper profile 211 and the anti-drop component 60 to be screwed out from the top of the fan frame upper profile 211 before detaching the fan-side connecting assembly 32 from the top of the fan frame upper profile 211.

[0083] Preferably, after the fan side connection assembly 32 of the upper hinge mechanism 30 is fixed to the top of the fan frame upper profile 211, the tightening operation through hole 321 and the anti-falling component 60 can have multiple positional relationships, so that the anti-falling component 60 and the fan side connection assembly 32 are fixed in different orders at the top of the fan frame upper profile 211.

[0084] For example, when the fan-side connection assembly 32 of the upper hinge mechanism 30 is fixed to the top of the fan frame upper profile 211, the tightening operation through hole 321 is distributed on the right side of the anti-falling component 60. In this way, when the fan-side connection assembly 32 is slid from the right end of the installation groove 23 to the left into the installation groove 23, the fan-side connection assembly 32 is first slid to the left to the position where the tightening operation through hole 321 is opposite to the fixed threaded hole 24, so that the anti-falling component 60 is screwed into the fixed threaded hole 24 through the tightening operation through hole 321; then, the fan-side connection assembly 32 is retreated to the right for a distance to its fixed position; finally, the locking member 50 is used to fix the fan-side connection assembly 32 to the fan frame upper profile 211. This method is the most commonly used method in practice and is the preferred method.

[0085] For another example: 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, the tightening operation through hole 321 is distributed on the left side of the anti-falling component 60. In this way, when the fan-side connecting assembly 32 is slid from the right end of the installation groove 23 to the left into the installation groove 23, the fan-side connecting assembly 32 is first slid to the left to the position where the tightening operation through hole 321 is directly opposite to the fixing threaded hole 24, so that the anti-falling component 60 is screwed into the fixing threaded hole 24 through the tightening operation through hole 321; then, the fan-side connecting assembly 32 is further slid to the left for a distance, so that the fan-side connecting assembly 32 is moved to the left to its fixed position; finally, the locking member 50 is used to fix the fan-side connecting assembly 32 to the fan frame upper profile 211.

[0086] For another example, after the sash-side connecting assembly 32 of the upper hinge mechanism 30 is fixed to the top of the sash frame upper profile 211, the tightening operation through-hole 321 is located directly above the anti-dropping component 60. Thus, after the sash-side connecting assembly 32 is slid from the right end of the mounting slot 23 to the left and into position, the tightening operation through-hole 321 is aligned with the fixing threaded hole 24. The anti-dropping component 60 can be screwed in through the tightening operation through-hole 321 first, and then the locking member 50 can be used to lock the sash-side connecting assembly 32. Alternatively, the locking member 50 can be used to lock the sash-side connecting assembly 32 first, and then the anti-dropping component 60 can be screwed in through the tightening operation through-hole 321.

[0087] Furthermore, if Figure 4 and Figure 5 As shown, the mounting groove 23 on the top of the sash frame upper profile 211 is a C-shaped groove, and the structure of the C-shaped groove is as follows: a pair of mounting arms 25 are provided on the top surface of the sash frame upper profile 211, and the pair of mounting arms 25 extend straight left and right along the length direction of the sash frame upper profile 211, and the pair of mounting arms 25 are arranged relatively front and back along the thickness direction of the sash frame upper profile 211, and the mounting arms 25 are in an inverted L-shape, and a 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 mounting arms 25.

[0088] Furthermore, the preferred structure of the fan-side connecting assembly 32 in the upper hinge mechanism 30 is as follows: Figure 6 and Figure 7 As shown, the fan-side connecting assembly 32 includes an adjustment seat 322, a connecting seat 324, and a fan-side hinge plate 323. The adjustment seat 322 is located on the left side of the connecting seat 324. The adjustment seat 322 and the connecting seat 324 are connected by an adjustment bolt 326 that extends straight along the extension direction of the mounting slot 23. The adjustment bolt 326 is rotatably supported in the adjustment seat 322 and threaded into the left end of the connecting seat 324. The right end of the connecting seat 324 is fixedly connected to the left end of the fan-side hinge plate 323, and the fan-side hinge plate 323 is connected to the frame-side connecting assembly 31 via the rotating connecting assembly 33. The connecting seat 324 is a sheet metal part, and the tightening operation through-hole 321 is opened in the right section of the fan-side hinge plate 323 and passes through the fan-side hinge plate 323 vertically along the thickness direction of the fan-side hinge plate 323. When installing the sash-side connecting assembly 32 on top of the sash frame upper profile 211, first slide the adjustment seat 322 and the connecting seat 324 leftward into the mounting slot 23. Once fully engaged, secure the adjustment seat 322 to the sash frame upper profile 211 using the locking member 50, which is a locking screw with two front and rear locking members 50. After the door and window are assembled, rotating the adjusting bolt 326 causes the adjustment seat 322 to move relative to the connecting seat 324 and the sash-side hinge plate 323. The adjustment seat 322 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.

[0089] Preferably, if Figure 6 and Figure 7 As shown, the adjustment seat 322 and the connecting seat 324 are connected by a pre-assembled structure 327. During the transportation of the doors and windows, the pre-assembled structure 327 ensures that the adjustment bolt 326 is reliably maintained in the pre-assembled state between the adjustment seat 322 and the connecting seat 324, thereby preventing the adjustment seat 322 from accidentally falling off the connecting seat 324 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 327 between the adjustment seat 322 and the connecting seat 324 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.

[0090] 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 322 and the bottom of the connecting seat 324 are both accommodated in the mounting groove 23, and the connecting seat 324 is entirely located on the left side of the anti-drop component 60. The sash-side hinge plate 323 is located above the mounting groove 23, and the sash-side hinge plate 323 is also located above the anti-drop component 60. In this way, when the door and window are in a normal state, the sash-side connecting assembly 32 is in a locked state fixed to the sash frame upper profile 211, and neither the connecting seat 324 nor the sash-side hinge plate 323 will contact the anti-slip protrusion 61 on the top of the anti-drop component 60. The anti-slip protrusion 61 is located in the area below the sash-side hinge plate 323 and to the right of the connecting seat 324, thereby preventing the vibration generated by the upper hinge mechanism 30 from being transmitted to the anti-drop component 60. When an accident occurs to the door or window, after the locking piece 50 is completely loosened, the adjusting seat 322 and the connecting seat 324 slide to the right from the mounting groove 23. When the right end of the connecting seat 324 slides to the right to the anti-fall component 60, the right end of the connecting seat 324 abuts against the left end of the anti-slip protrusion 61. The fixed anti-slip protrusion 61 forms a stop for the rightward sliding of the connecting seat 324, restricting the connecting seat 324 there, preventing the connecting seat 324 from sliding out of the 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.

[0091] Furthermore, if Figure 2 and Figure 3 ,as well as Figure 6 and Figure 7 As shown, along the thickness direction of the sash frame upper profile 211, limiting ribs 325 are provided on the front and rear sides of the bottom of the adjustment seat 322 and the front and rear sides of the bottom of the connecting seat 324. The limiting ribs 325 are locked in the mounting arms 25. In this way, after the adjustment seat 322 and the connecting seat 324 of the sash-side connecting assembly 32 slide leftward into the mounting groove 23, the pair of mounting arms 25 abut against the front and rear sides of the adjustment seat 322 and the connecting seat 324, limiting the displacement of the sash-side connecting assembly 32 in the vertical direction and the front and rear direction, so that the sash-side connecting assembly 32 can only slide left and right along the extension direction of the 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 mounting groove 23.

[0092] In summary, the high load-bearing hinge structure for doors and windows involved in this application has the following advantages.

[0093] 1. By simply adding a screw constituting the anti-falling component 60, when the sash-side connecting assembly 32 of the upper hinge mechanism 30 accidentally slips out of the mounting groove 23, the anti-falling component 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, and the structure is simple and the cost is low.

[0094] 2. When the doors and windows are in normal condition, the fan-side connecting assembly 32 of the upper hinge mechanism 30 does not contact the anti-falling component 60, and the vibration of the upper hinge mechanism 30 will not be transmitted to the anti-falling component 60. The anti-falling component 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-falling fan.

[0095] In summary, the present invention effectively overcomes various shortcomings of the prior art and has high industrial utilization value.

[0096] 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.
