Description

Technical Field

[0001] The present invention relates to the technical field of hinges, and particularly to a high-load wind-resistant hinge. Background Art

[0002] There are various styles of windows on the market, including casement windows, sliding windows, and awning windows. Windows on the existing market mainly consist of window frames and window sashes. The connection between the window frame and the window sash determines the safety and reliability of the doors and windows. In addition, the connection effect of the window sash also affects various performances of the doors and windows. Currently, the window frame and the window sash generally adopt hinges for connection. Since the hinge has to bear the weight of the window sash and support the rotation of the window sash, the load-bearing performance of the hinge largely determines the service life of the doors and windows.

[0003] Most of the existing door and window hinges are set by stacking connecting rods and fixing them at one riveting hole position. In order to better fix them, it is necessary to reduce the thickness of the connecting rods, which will reduce the load-bearing capacity of the door and window hinges. If the corresponding thickness of the connecting rods is maintained for the load-bearing capacity, the stability of the connecting rods will be reduced. The Chinese Patent Authorization Publication No. is CN 220645596 U, which discloses an anti-wind-pressure hinge. The anti-wind-pressure hinge mainly has the following several defects: 1. One end of the first connecting rod is connected to the bottom plate by a hinged manner, and the window sash is fixed on the mounting plate. When the window sash is installed, due to the downward gravity, the hinged end of the first connecting rod will tilt up. Since this end is only fixed by hinging, the force after the hinged end of the first connecting rod tilts up cannot be decomposed. After a long time, it is easy to cause the connection of the window sash to be unstable and the wind resistance performance to be poor.

[0004] 2. One end of the first connecting rod and the hinged end of the bottom plate are fixed to rotate at the same position, so that the distance between the hinged end and the jack is fixed. That is to say, the distance between one side of the window sash and the wall is fixed, and only a gap is formed by the rotation method. In this way, the position between the back of the window sash and the window sash and the wall is too small, resulting in inconvenience for the hand to reach in for cleaning. Summary of the Invention

[0005] In order to overcome the above deficiencies existing in the prior art, the purpose of the present invention is to provide a high-load wind-resistant hinge, which can effectively improve the load-bearing capacity and wind resistance ability of the door and window hinge.

[0006] The present invention is achieved through the following technical solutions: A high-load wind-resistant hinge, comprising a bottom plate and an opening / closing mechanism. The opening / closing mechanism has an opening / closing end and a connecting end. The opening / closing mechanism includes a long arm, a middle arm, a support arm, and a cantilever. One side of the bottom plate is provided with a chute, and a sliding member is slidably arranged in the chute. The opposite ends of the long arm are respectively hinged to the bottom 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 are respectively hinged to the sliding member and the support arm. When the sliding member slides along the chute, it drives the opening / closing end to form an open state or a coincident state relative to the bottom plate. The hinge points between the long arm, the middle arm, the cantilever, and the support arm are all different.

[0007] Preferably, on one side of the upper surface of the bottom plate of the present invention, there is a folding plate. A chute for the sliding member to slide is formed between the folding plate and the bottom plate. One end of the chute is open, and a limiting structure is provided at the other end.

[0008] Preferably, the limiting structure of the present invention is a limiting pin. The limiting pin passes through the folding plate and is fastened to the bottom plate to enable the sliding member to slide to the extreme position.

[0009] Preferably, the sliding member of the present invention includes a sliding member body slidably arranged in the chute, a first wear-resistant sheet formed on one side of the sliding member, a second wear-resistant sheet hinged to one end of the sliding member. A support member hinged to one end of the middle arm is provided on the first wear-resistant sheet, and the cantilever is fixed on the second wear-resistant sheet.

[0010] Preferably, the sliding member, the first wear-resistant sheet, and the second wear-resistant sheet of the present invention are all made of nylon material.

[0011] Preferably, the width of the folding plate of the present invention is smaller than the width of the bottom plate. When the opening / closing end forms a coincident state relative to the bottom plate, a width is reserved for accommodating the widths 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 in sequence along the length direction of the bottom plate.

[0012] Preferably, a window frame mounting member for connecting to the window frame is provided at the bottom of the bottom plate of the present invention. A stepped body and an inclined surface are formed on the window frame mounting member.

[0013] Preferably, a window sash mounting member is provided on the support arm and is vertically connected thereto.

[0014] Preferably, when the support arm rotates relative to the bottom plate to the extreme position, the cantilever abuts against the second wear-resistant sheet.

[0015] Compared with the prior art, the present invention has the following advantages and beneficial effects: 1. The present invention is provided with a folding plate on the bottom plate, so as to form a sliding groove between the folding plate and the bottom plate, enabling the support arm and the middle arm to transfer the force under the gravity of the window sash to the folding plate for decomposition when bearing the gravity of the window sash. Compared with the prior art where the force is only borne by a single riveting point, problems such as the hinged end tilting up, the window sash being unstable, and poor wind resistance are less likely to occur.

[0016] 2. The support arm of the present invention is supported by the middle arm and the cantilever. Compared with the prior art where it is only supported by a single cantilever, it can provide a greater support force for the window sash and can use a shorter cantilever, enabling the support arm to bear a heavier window sash.

[0017] 3. After the opening and closing mechanism of the present invention is opened, when the support arm rotates to the limit position relative to the bottom plate, the second wear-resistant piece can abut against the cantilever. When the window sash is subjected to wind pressure, the cantilever is abutted by the second wear-resistant piece, making the window sash more stable after being subjected to wind pressure, thereby improving the wind resistance strength of the window sash.

In the description of the present invention, unless otherwise specified, the meaning of "a plurality of" is two or more.

[0021] In the description of the present invention, it should be noted that, unless otherwise clearly specified and defined, the terms "mounted", "connected" and "coupled" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection or an integral connection; it may be a mechanical connection or an electrical connection; it may also be directly connected or indirectly connected through an intermediate medium, and may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0022] Referring to Figures 1 to 4 As shown, this embodiment provides a high-load wind-resistant hinge, which includes a bottom plate 1 and an opening and closing mechanism 2. The opening and closing mechanism 2 has an opening and closing end 20 and a connection end 21.

[0023] Among them, the opening and closing mechanism includes a long arm 3, a middle arm 4, a support arm 5 and a cantilever 6. A chute 10 is provided on one side of the bottom plate 1, and a sliding member 7 is slidably arranged in the chute 10. The opposite ends of the long arm 3 are respectively hinged to the bottom plate 1 and the support arm 5, the opposite ends of the middle arm 4 are respectively hinged to the sliding member 7 and the support arm 5, the opposite ends of the cantilever 6 are respectively hinged to the sliding member 7 and the support arm 5, and the hinge points between the long arm 3, the middle arm 4, the cantilever 6 and the support arm 5 are all different; when the sliding member 7 slides along the chute 10, it drives the opening and closing end 20 to form an open state or a coincident state relative to the bottom plate 1; it can be understood that the bottom plate 1 is installed in the window frame, and the opening and closing mechanism 2 is installed on the window sash. By sliding the sliding member 7 along the chute 11, the opening and closing end 20 of the opening and closing mechanism 2 forms an open state relative to the bottom plate 1, and at this time the window sash is opened relative to the window frame; by sliding the sliding member 7 along the chute 11 direction, the opening and closing end 20 of the opening and closing mechanism 2 forms a coincident state relative to the bottom plate 1, and at this time the window sash is closed relative to the window frame.

[0024] In order to form a chute on the bottom plate 1 for the slider to slide, a folding plate 11 is provided on one side of the upper surface of the bottom plate 1. The folding plate 11 and the bottom plate 1 are of an integral structure. The folding plate 11 is formed on the bottom plate by bending, so that a chute 10 for the slider 7 to slide is formed between the folding plate 11 and the bottom plate 1. One end of the chute 10 is open, and a limiting structure is provided at the other end. The limiting structure is a limiting pin 12. The limiting pin 12 passes through the folding plate 11 and is fastened to the bottom plate 1, so that the slider 7 slides to the limit position, so that when the opening and closing mechanism rotates relative to the bottom plate 1, it will not exceed the limit position, thereby avoiding damage caused by excessive rotation of the hinge.

[0025] Therefore, the high-load wind-resistant hinge drives the opening and closing end 20 of the opening and closing mechanism 2 to form an open state or a coincident state relative to the bottom plate 1 through the slider 7 sliding along the chute 11, thereby driving the window sash to form an open state or a closed state relative to the window frame. Among them, the slider 7 is arranged in the chute 11, so that the slider 7 can drive the middle arm 4, the support arm 5 and the cantilever 6 to slide to open or close the window sash, so that the support arm 5 and the middle arm 4 can transmit the force to the folding plate 11 for decomposition under the gravity of the window sash. Compared with the prior art where the force is only applied through a riveting point, problems such as the hinge end warping, the window sash being unstable, and poor wind resistance are not likely to occur.

[0026] In some embodiments, the slider 7 includes a slider body 70 slidably disposed in the chute, a first wear-resistant sheet 71 formed on one side of the slider. The first wear-resistant sheet 71 and the slider body 70 are of an integral structure. One end of the slider 7 is provided with a second wear-resistant sheet 72 hinged thereto. A support member 40 hinged to one end of the middle arm 4 is provided on the first wear-resistant sheet 71. The cantilever 6 is fixed on the second wear-resistant sheet 72. The slider 7, the first wear-resistant sheet 71 and the second wear-resistant sheet 72 are all made of nylon material.

[0027] With such a setting, through the cooperation of the first wear-resistant sheet 71 and the second wear-resistant sheet 72, on the one hand, the wind resistance of the hinge can be improved, and on the other hand, it can effectively prevent the support member 40 and the cantilever 6 from wearing against the bottom plate 1 during the sliding process, reduce the wear of components, improve the service life of the hinge, and it is not easy to reduce the support force of the components after the support member 40 and the cantilever 6 are worn.

[0028] In some embodiments, the width of the folding plate 11 is smaller than the width of the bottom plate 1, so that when the opening and closing end 20 forms a coincident state relative to the bottom plate 1, a width can be reserved for accommodating the widths 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 in sequence along the length direction of the bottom plate 1.

[0029] In some embodiments, a window frame mounting member 8 for connecting with a window frame is provided at the bottom of the bottom plate 1. A stepped body and an inclined surface are formed on the window frame mounting member 8. The formation of the inclined surface structure on the window frame mounting member 8 enables this high-load hinge to be applicable to profiles with different thicknesses. The window frame mounting member 8 can be fixed to the bottom plate 1 through an internal hexagon rivet 80. When installed on the window frame, the internal hexagon rivet is rotated 90 degrees and clamped into the profile notch of the window frame, making the sash safer.

[0030] In some embodiments, a sash mounting member 9 perpendicular to the support arm 5 is provided on the support arm 5. The sash mounting member 9 can be a mounting plate or a mounting shaft; specifically, the sash mounting member 9 is an existing conventional technology. Therefore, the structure of the sash mounting member 9 is not specifically described in the present invention.

[0031] In some embodiments, to further enhance the wind resistance strength of the hinge, when the support arm 5 rotates relative to the bottom plate 1 to the limit position, the cantilever 6 abuts against the second wear-resistant piece 72. When the opening and closing mechanism opens relative to the bottom plate 1 and the support arm 5 rotates relative to the bottom plate 1 to the limit position, the second wear-resistant piece 72 can abut against the cantilever 6. When the sash is subjected to wind pressure, the cantilever 6 is abutted by the second wear-resistant piece, making the sash more stable after being subjected to wind pressure, thereby improving the wind resistance strength of the sash.

[0032] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and purposes of the present invention. The scope of the present invention is defined by the claims and their equivalents.
