Description

Technical Field

[0001] This utility model relates to the field of hinge technology, specifically to a high load-bearing and wind-resistant hinge. Background Technology

[0002] There are various styles of windows on the market, including folding windows, sliding windows, and casement windows. Current windows mainly consist of a frame and a sash. The connection between the frame and sash determines the safety and reliability of the door or window. Furthermore, the quality of the sash connection also affects various aspects of the door's performance. Currently, window frames and sashes are generally connected by hinges. Because the hinges must bear the weight of the sash and support its rotation, their load-bearing capacity largely determines the lifespan of the door or window.

[0003] Existing door and window hinges mostly use overlapping connecting rods fixed at a single rivet hole. To achieve better fixation, the connecting rod thickness needs to be reduced, which decreases the hinge's load-bearing capacity. Conversely, maintaining the same connecting rod thickness to maintain load-bearing capacity reduces the connecting rod's stability. Chinese Patent Publication No. CN 220645596 U discloses a wind-pressure resistant hinge, which has the following main drawbacks:

[0004] 1. One end of the first connecting rod is connected to the base plate by a hinge, and the window sash is fixed on the mounting plate. When the window sash is installed, it will be subjected to downward gravity, which will cause the hinge end of the first connecting rod to tilt up. Since this end is only fixed by a hinge, the force after the hinge end of the first connecting rod tilts up cannot be distributed. Over time, this will easily cause the window sash to be not firmly connected and have poor wind resistance.

[0005] 2. One end of the first connecting rod is fixed in the same position as the hinge end of the base plate and rotates so that the distance between the hinge end and the socket is fixed. That is to say, the distance between one side of the window sash and the wall is fixed. The gap is only formed by rotation. This results in the back of the window sash and the space between the window sash and the wall being too small, making it inconvenient for hands to reach in for cleaning. Utility Model Content

[0006] In order to overcome the above-mentioned shortcomings in the existing technology, the purpose of this utility model is to provide a high load-bearing and wind-resistant hinge, which can effectively improve the load-bearing capacity and wind resistance of door and window hinges.

[0007] This utility model is achieved through the following technical solution: a high load-bearing and wind-resistant hinge, including a base plate and an opening and closing mechanism. The opening and closing mechanism has an opening and closing end and a connecting end. The opening and closing mechanism includes a long arm, a middle arm, a support arm, and a cantilever arm. A sliding groove is provided on one side of the base plate. A sliding member is provided in the sliding groove. The opposite ends of the long arm are respectively hinged to the base plate and the support arm. The opposite ends of the middle arm are respectively hinged to the sliding member and the support arm. The opposite ends of the cantilever arm are respectively hinged to the sliding member and the support arm. When the sliding member slides along the sliding groove, it drives the opening and closing end to form an open state or an overlapping state relative to the base plate. The hinge points between the long arm, the middle arm, the cantilever arm, and the support arm are all different.

[0008] Preferably, the base plate of the present invention has a folding plate on one side of its upper surface, and a sliding groove is formed between the folding plate and the base plate for the sliding member to slide. One end of the sliding groove is open, and the other end is provided with a limiting structure.

[0009] Preferably, the limiting structure of this utility model is a limiting pin, which passes through the folding plate and is fastened to the base plate so that the sliding member slides to the limit position.

[0010] Preferably, the sliding member of this utility model includes a sliding member body slidably disposed in a sliding groove, a first wear-resistant plate formed on one side of the sliding member, a second wear-resistant plate hinged to one end of the sliding member, a support member hinged to one end of the first wear-resistant plate, and the cantilever fixed on the second wear-resistant plate.

[0011] Preferably, the sliding component, the first wear-resistant plate, and the second wear-resistant plate of this invention are all made of nylon material.

[0012] Preferably, the width of the folding plate of this utility model is smaller than the width of the base plate, so that when the opening and closing ends overlap with the base plate, the width can be reserved to accommodate the width of the long arm, the middle arm and the support arm, and the long arm, the middle arm, the cantilever and the support arm are arranged sequentially along the length direction of the base plate.

[0013] Preferably, the bottom of the base plate of the present invention is provided with a window frame mounting component for connecting with the window frame, and the window frame mounting component has a stepped body and a slope.

[0014] Preferably, the support arm of this utility model is provided with a window sash mounting component that is vertically connected to it.

[0015] Preferably, when the support arm of this invention rotates to its limit position relative to the base plate, the cantilever abuts against the second wear-resistant sheet.

[0016] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0017] 1. This utility model has a folding plate on the base plate, so that a groove is formed between the folding plate and the base plate. This allows the support arm and the middle arm to transfer the force to the folding plate for dispersal when bearing the weight of the window sash. Compared with the prior art, which only uses a single rivet point to bear the force, it is less likely to cause problems such as the hinge end lifting, the window sash being unstable, and poor wind resistance.

[0018] 2. The support arm of this utility model is supported by a middle arm and a cantilever arm. Compared with the existing technology that is supported by only one cantilever arm, it can provide greater support for the window sash and can use a shorter cantilever arm, so that the support arm can bear a heavier window sash.

[0019] 3. When the opening and closing mechanism of this utility model is opened, the second wear-resistant plate can abut against the cantilever when the support arm rotates to the limit position relative to the base plate. When the window sash is subjected to wind pressure, the cantilever is abutted by the second wear-resistant plate, making the window sash more stable after being subjected to wind pressure, thereby improving the wind resistance strength of the window sash.

[0037] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0038] Reference Figures 1 to 4 As shown, this embodiment provides a high load-bearing and wind-resistant hinge, including a base plate 1 and an opening and closing mechanism 2, the opening and closing mechanism 2 having an opening and closing end 20 and a connecting end 21.

[0039] The opening and closing mechanism includes a long arm 3, a middle arm 4, a support arm 5, and a cantilever 6. A groove 10 is provided on one side of the base plate 1, and a sliding member 7 is slidably disposed within the groove 10. The opposite ends of the long arm 3 are hinged to the base plate 1 and the support arm 5, respectively. The opposite ends of the middle arm 4 are hinged to the sliding member 7 and the support arm 5, respectively. The opposite ends of the cantilever 6 are hinged to the sliding member 7 and the support arm 5, respectively. The hinge points of the long arm 3, the middle arm 4, the cantilever 6, and the support arm 5 are all different. The sliding member 7... When the slide groove 10 slides, it causes the opening and closing end 20 to form an open or overlapping state relative to the base plate 1. It can be understood that the base plate 1 is installed in the window frame, and the opening and closing mechanism 2 is installed on the window sash. The sliding member 7 slides along the slide groove 10, causing the opening and closing end 20 of the opening and closing mechanism 2 to form an open state relative to the base plate 1. At this time, the window sash is open relative to the window frame. The sliding member 7 slides along the slide groove 10, causing the opening and closing end 20 of the opening and closing mechanism 2 to form an overlapping state relative to the base plate 1. At this time, the window sash is closed relative to the window frame.

[0040] To create a sliding groove for the sliding member on the base plate 1, a folding plate 11 is provided on one side of the upper surface of the base plate 1. The folding plate 11 is an integral structure with the base plate 1. The folding plate 11 is formed on the base plate by bending, so that a sliding groove 10 for the sliding member 7 is formed between the folding plate 11 and the base plate 1. One end of the sliding groove 10 is open, and the other end is provided with a limiting structure, wherein the limiting structure is a limiting pin 12. The limiting pin 12 passes through the folding plate 11 and is fastened to the base plate 1, so that the sliding member 7 slides to the limit position, thereby preventing the opening and closing mechanism from exceeding the limit position when rotating relative to the base plate 1, and thus avoiding damage to the hinge due to excessive rotation.

[0041] Therefore, the high load-bearing and wind-resistant hinge drives the opening and closing end 20 of the opening and closing mechanism 2 to form an open or overlapping state relative to the bottom plate 1 through the sliding member 7 sliding along the slide groove 10, thereby driving the window sash to form an open or closed state relative to the window frame. The sliding member 7 is set in the slide groove 10 so that the sliding member 7 can drive the middle arm 4, the support arm 5 and the cantilever 6 to slide to open or close the window sash. Under the weight of the window sash, the support arm 5 and the middle arm 4 can transfer the force to the folding plate 11 for decomposition. Compared with the existing technology that only uses a single rivet point to bear the force, it is less likely to have problems such as the hinge end lifting, the window sash being unstable, and poor wind resistance.

[0042] In some embodiments, the slider 7 includes a slider body 70 slidably disposed in a groove and a first wear-resistant plate 71 formed on one side of the slider. The first wear-resistant plate 71 and the slider body 70 are integrally formed. One end of the slider 7 is provided with a second wear-resistant plate 72 hinged thereto. The first wear-resistant plate 71 is provided with a support member 40 hinged to one end of the middle arm 4. The cantilever 6 is fixed on the second wear-resistant plate 72. The slider 7, the first wear-resistant plate 71 and the second wear-resistant plate 72 are all made of nylon material.

[0043] With this configuration, the first wear-resistant plate 71 and the second wear-resistant plate 72 work together to improve the hinge's wind resistance and effectively prevent wear between the support member 40 and the cantilever 6 and the base plate 1 during sliding. This reduces wear on the components, extends the service life of the hinge, and prevents the support member 40 and the cantilever 6 from wearing down and reducing the supporting force of the components.

[0044] In some embodiments, the width of the folding plate 11 is smaller than the width of the base plate 1, so that when the opening end 20 overlaps with the base plate 1, the width can be reserved to accommodate the width of the long arm 3, the middle arm 4 and the support arm 5, and the long arm 3, the middle arm 4, the cantilever 6 and the support arm 5 are arranged sequentially along the length direction of the base plate 1.

[0045] In some embodiments, the bottom of the base plate 1 is provided with a window frame mounting member 8 for connection with the window frame. The window frame mounting member 8 has a stepped body and a bevel. The beveled structure of the window frame mounting member 8 allows the high load-bearing hinge to be applicable to profiles of different thicknesses. The window frame mounting member 8 can be fixed to the base plate 1 by means of hexagonal rivets 80. When installed on the window frame, the hexagonal rivets are rotated 90 degrees and locked into the profile groove of the window frame, which improves the safety of the window sash.

[0046] In some embodiments, the support arm 5 is provided with a window sash mounting component 9 that is vertically connected thereto. The window sash mounting component 9 may be a mounting plate or a mounting shaft. Specifically, the window sash mounting component 9 is a conventional technology. Therefore, the present invention will not describe the structure of the window sash mounting component 9 in detail.

[0047] In some embodiments, the wind resistance of the hinge is further improved. When the support arm 5 rotates to its limit position relative to the base plate 1, the cantilever 6 abuts against the second wear-resistant plate 72. When the opening and closing mechanism opens relative to the base plate 1, and the support arm 5 rotates to its limit position relative to the base plate 1, the second wear-resistant plate 72 can abut against the cantilever 6. When the window sash is subjected to wind pressure, the cantilever 6 is abutted by the second wear-resistant plate, making the window sash more stable after being subjected to wind pressure, thereby improving the wind resistance of the window sash.

[0048] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
