Description

Technical Field

[0001] The present application belongs to the field of hinge technology, and in particular relates to a modular ultra-thin hinge for aluminum windows and doors. Background Art

[0002] Hinges can be used to connect two objects and allow them to rotate relative to each other. They are widely used in construction, machinery, furniture and other fields. For example, as a connecting part between a door and a cabinet, the two ends of the hinge are fixed to the door and the cabinet respectively, and the hinge arm can rotate relative to the two ends connecting the door and the cabinet to open and close the door.

[0003] When adjusting the obstruction area of ​​a door using a hinge, existing hinges typically rotate a hinge arm to lift one end relative to the hinge cup, thereby moving the door connected to the other end of the hinge arm. However, when the hinge arm is lifted, the connection between the hinge arm and the cabinet body is subjected to a large overhanging force. Over time, this can easily cause the connection between the hinge arm, the door body, and the cabinet body to loosen or even fall off, thereby shortening the service life of the hinge.

[0004] Moreover, adjusting the door body by rotating the hinge arm will cause one end of the door window to lift relative to the cabinet body, that is, the angle between the door body and the cabinet body will become non-right angles, thereby increasing the gap between the door body and the cabinet body, and causing the door body to sink inward relative to the opening of the cabinet body, resulting in an uneven overall appearance.

[0005] It should be noted that the above content is not necessarily prior art, nor is it intended to limit the scope of patent protection of this application. Utility Model Content

[0006] The embodiments of the present application provide a modular ultra-thin hinge for aluminum windows and doors to solve or alleviate one or more technical problems in the prior art.

[0007] A first aspect of an embodiment of the present application provides a modular ultra-thin hinge for aluminum windows and doors, comprising:

[0008] Chassis, used for fixed connection with aluminum windows and doors;

[0009] a hinge arm, one end of which is hinged to the chassis;

[0010] Sliding hinge cup, including:

[0011] a first base, wherein a guide groove is provided on the first base, and the first base is used for being fixedly connected to the cabinet;

[0012] a second base, the second base being slidably mounted in the guide groove, the second base being used for being rotatably connected to a hinge arm, the hinge arm being hinged to the aluminum window door;

[0013] an eccentric bolt, which is passed through the first base and riveted to the second base, and the eccentric bolt can rotate axially to drive the second base to slide horizontally along the guide groove relative to the first base, thereby driving the aluminum window door to slide horizontally relative to the cabinet body;

[0014] A first notch is formed on the first base body and is used for allowing the second base body to enter the first notch of the guide groove. The first notch is communicated with one end of the guide groove.

[0015] Optionally, the second substrate includes:

[0016] base plate;

[0017] a first side plate, fixed vertically to the first end of the bottom plate;

[0018] a second side plate, fixed vertically to the second end of the bottom plate;

[0019] The bottom plate, the first side plate and the second side plate are arranged to form a receiving groove, and the receiving groove is used to receive part of the hinge arm.

[0020] Optionally, the guide groove comprises a first inner wall and a second inner wall opposite to each other, the first inner wall is provided with a first guide rail along the length direction of the guide groove, and the second inner wall is provided with a second guide rail along the length direction of the guide groove;

[0021] A first slider is provided on the outer side of the first side plate of the second base body, and a second slider is provided on the outer side of the second side plate of the second base body;

[0022] The first slider is slidably installed in the first guide rail, and the second slider is slidably installed in the second guide rail.

[0023] Optionally, the first sliding block is a rectangular block.

[0024] Optionally, the first base further includes two opposite outer walls, each outer wall is provided with a fixing block, and the fixing block is used to be fixedly connected to the cabinet.

[0025] Optionally, the first base further includes a fixing piece, the fixing block is provided with a fixing hole, and the fixing piece is passed through the fixing hole to be fixedly connected to the cabinet.

[0026] Optionally, a first positioning hole is formed on the first side panel, and a second positioning hole is formed on the second side panel, and the first positioning hole and the second positioning hole are arranged opposite to each other;

[0027] The modular aluminum window and door ultra-thin hinge also includes a first rotating shaft, which is arranged between the first positioning hole and the second positioning hole. The first rotating shaft is also rotatably connected to the hinge arm so that the second base and the hinge arm can rotate based on the axis of the first rotating shaft.

[0028] The above technical solution adopted in the embodiments of the present application may have the following advantages:

[0029] The second base can slide along the guide groove in the first base to drive the hinge arm to slide relative to the first base, which is equivalent to driving the hinge arm to slide horizontally relative to the cabinet body, rather than rotating the hinge arm relative to the first base. Therefore, the relative height of the hinge arm and the first base is always unchanged, and the relative height of the hinge arm and the cabinet body is also unchanged. Therefore, when adjusting the relative position of the second base and the first base, the cantilever force on the connection part of the hinge arm and the cabinet body will not increase, so that the connection between the hinge arm and the door body and the cabinet body is not easy to loosen, thereby improving the service life of the hinge.

[0030] And since the second base moves horizontally relative to the first base, this adjustment is reflected in the horizontal movement of the door body, that is, what is adjusted is the horizontal sliding position of the door body in the closed state. The angle between the door body and the cabinet body remains unchanged, avoiding the appearance of obvious gaps between the door body and the cabinet body, and also avoiding the door body being concave or convex relative to the cabinet opening, resulting in an uneven overall appearance.

DETAILED DESCRIPTION

[0042] Embodiments of the present application are described in detail below, with examples of the embodiments illustrated in the accompanying drawings. In the accompanying drawings, the sizes of layers, regions, and components, as well as their relative sizes, may be exaggerated for clarity. Throughout, the same or similar reference numerals represent the same or similar components or components having the same or similar functions. The embodiments described below with reference to the accompanying drawings are illustrative and intended only to explain the present application, and are not to be construed as limiting the present application.

[0043] It should be understood that when an element or layer is referred to as being "on," "adjacent to," "connected to," or "coupled to" another element or layer, it can be directly on, adjacent to, connected to, or coupled to the other element or layer, or there can be intervening elements or layers. Conversely, when an element is referred to as being "directly on," "directly adjacent to," "directly connected to," or "directly coupled to" another element or layer, there are no intervening elements or layers. It should be understood that while the terms first, second, third, etc. may be used to describe various elements, components, regions, layers, and / or portions, these elements, components, regions, layers, and / or portions should not be limited by these terms. These terms are merely used to distinguish one element, component, region, layer, or portion from another. Thus, without departing from the teachings of the present application, a first element, component, region, layer, or portion discussed below may be represented as a second element, component, region, layer, or portion. Furthermore, when a second element, component, region, layer, or portion is discussed, it does not necessarily mean that the first element, component, region, layer, or portion is present in the present application.

[0044] In this application, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. Those skilled in the art will understand the specific meanings of the above terms in this application based on specific circumstances.

[0045] It should be noted that the terms "first", "second", etc. in the specification and claims of this application and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that the terms used in this way are interchangeable where appropriate, so that the embodiments of the application described herein can, for example, be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0046] In the present application, when it comes to a numerical interval (i.e., a numerical range), unless otherwise specified, the distribution of the optional numerical values ​​in the numerical interval is considered to be continuous, and includes the two numerical endpoints (i.e., the minimum and maximum values) of the numerical interval, and each numerical value between the two numerical endpoints. Unless otherwise specified, when the numerical interval only refers to an integer in the numerical interval, including the two endpoint integers of the numerical range, and each integer between the two endpoints, is equivalent to directly enumerating each integer. When multiple numerical ranges are provided to describe a feature or characteristic, these numerical ranges can be merged. In other words, unless otherwise specified, the numerical range disclosed in this application should be understood to include any and all subranges included therein. The "numerical value" in the numerical interval can be any quantitative value, such as a number, a percentage, a ratio, etc. "Numerical interval" allows broadly including quantitative intervals such as percentage intervals, ratio intervals, and ratio intervals.

[0047] Hinges can be used to connect two objects and allow them to rotate relative to each other. They are widely used in construction, machinery, furniture and other fields. For example, as a connecting part between a door and a cabinet, the two ends of the hinge are fixed to the door and the cabinet respectively, and the hinge arm can rotate relative to the two ends connecting the door and the cabinet to open and close the door.

[0048] When adjusting the obstruction area of ​​a door using a hinge, existing hinges typically rotate a hinge arm to lift one end relative to the hinge cup, thereby moving the door connected to the other end of the hinge arm. However, when the hinge arm is lifted, the connection between the hinge arm and the cabinet body is subjected to a large overhanging force. Over time, this can easily cause the connection between the hinge arm, the door body, and the cabinet body to loosen or even fall off, thereby shortening the service life of the hinge.

[0049] In addition, adjusting the door body by rotating the hinge arm will cause one end of the door window to lift relative to the cabinet body, that is, the angle between the door body and the cabinet body will become non-right angles, which will increase the gap between the door window and the cabinet body, and cause the door window to sink inward relative to the opening of the cabinet body, making the overall appearance uneven.

[0050] Based on this, the present invention provides a modular ultra-thin hinge for aluminum windows and doors. This alleviates the problem of the hinge arm, door body, and cabinet body becoming loose and detaching over time, thus shortening the hinge's service life, and alleviates the problem of the door body sag inward relative to the cabinet opening. See below for details.

[0051] Hereinafter, exemplary embodiments according to the present application will be described in more detail with reference to the accompanying drawings. It should be noted that these exemplary embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein.

[0052] See also Figures 1 to 7The embodiment of the present application provides a modular ultra-thin hinge for aluminum windows and doors, which includes a chassis 300, a hinge arm 200, a sliding hinge cup 100, and a first notch 13. Detailed description is given below:

[0053] Chassis 300 is used for fixed connection to the aluminum window door. In an optional embodiment, chassis 300 may include a first chassis, a second chassis, and an adjustment mechanism. The first chassis and the second chassis are both rectangular thin-sheet structures. The second chassis is stacked on the first side and clamped to the first chassis. The second chassis can provide additional support and stability for the first chassis. The adjustment mechanism may include a second eccentric bolt, which can be passed through the second chassis and riveted to the first chassis. The axial rotation of the second eccentric bolt can cause the second chassis and the first chassis to move left or right relative to each other, thereby adjusting the vertical position of the door body, that is, adjusting the height position of the door body, so that the door body is more compatible with the cabinet body and has a neater appearance.

[0054] One end of the hinge arm 200 is hinged to the chassis 300. That is, the modular aluminum window door ultra-thin hinge is fixed to the door body, and the chassis 300 is fixed to the cabinet body. The hinge arm 200 serves as a medium for relative rotation between the two, realizing the function of rotating the door body relative to the cabinet body.

[0055] The sliding hinge cup includes: a first base 10, a second base 20, and an eccentric bolt 30, which are described in detail below:

[0056] A guide groove 11 is provided on the first base 10 , and the first base 10 is used for fixed connection with the cabinet.

[0057] The second base 20 is slidably mounted within the guide slot 11 and is rotatably connected to the hinge arm, which is hinged to the aluminum window door. The first base 10 serves as a fixed member connected to the cabinet body, serving as a connecting medium between the second base 20 and the cabinet body. The hinge arm can include a connecting arm and a connecting plate, which are connected to the second base 20 via different rotating shafts to enhance the overall flexibility of the hinge arm's rotation.

[0058] The eccentric bolt 30 is passed through the adjustment hole on the first base 10 and riveted to the second base 20. The eccentric bolt 30 can rotate axially to drive the second base 20 to slide horizontally along the guide groove 11 relative to the first base 10, thereby driving the aluminum window door to slide horizontally relative to the cabinet body.

[0059] A first notch 13 is formed on the first base 10 , and is used for allowing the second base 20 to enter the first notch 13 of the guide groove 11 . The first notch 13 is communicated with one end of the guide groove 11 .

[0060] The first notch 13 allows the second base 20 to enter the guide groove 11 directly from the notch position without forcibly inserting it from the side of the guide groove 11, making the installation of the second base 20 more convenient and reducing the complexity of the installation process.

[0061] When maintenance, replacement or adjustment is required, the second base body 20 can be easily taken out through the first notch 13 without removing the first base body 10 from the cabinet.

[0062] The modular ultra-thin hinge for aluminum windows and doors described above is illustrative. A cabinet has bifold doors, meaning one door is located at each end of the cabinet's opening, and the two doors cooperate to cover the cabinet opening. When adjusting the gap between the doors using the ultra-thin hinge, the two doors can be moved toward or away from each other to adjust the gap, preventing the doors from sag or bulge, resulting in an uneven appearance.

[0063] Preferably, the modular ultra-thin hinge for aluminum windows and doors according to the embodiment of the present application is suitable for aluminum window and door profiles (i.e., door bodies).

[0064] In this embodiment, since the second base 20 slides along the guide groove 11 in the first base 10 to drive the hinge arm to slide relative to the first base 10, it is equivalent to driving the hinge arm to slide horizontally relative to the cabinet body, rather than rotating the hinge arm relative to the first base 10 by rotating the hinge arm. Therefore, the relative height of the hinge arm and the first base 10 is always unchanged, and the relative height of the hinge arm and the cabinet body is also unchanged. Therefore, when adjusting the relative position of the second base 20 and the first base 10, the cantilever force on the connection part of the hinge arm and the cabinet body will not increase, so that the connection between the hinge arm and the door body and the cabinet body is not easy to loosen, thereby improving the service life of the hinge.

[0065] And since the second base 20 moves horizontally relative to the first base 10, this adjustment is reflected in the horizontal movement of the door body, that is, what is adjusted is the horizontal sliding position of the door body in the closed state. The angle between the door body and the cabinet body remains unchanged, avoiding the appearance of obvious gaps between the door body and the cabinet body, and also avoiding the door body being concave or convex relative to the cabinet opening, resulting in an uneven overall appearance.

[0066] In an optional embodiment, the second base 20 includes a bottom plate 23, a first side plate 21, and a second side plate 22. The first side plate 21 is vertically fixed to the first end of the bottom plate 23, and the second side plate 22 is vertically fixed to the second end of the bottom plate 23. The bottom plate 23, the first side plate 21, and the second side plate 22 form a receiving groove for accommodating a portion of the hinge arm. In this embodiment, the second base 20 is further provided with a second notch connected to the receiving groove to facilitate retraction of the hinge arm and prevent interference with the second base 20 when the hinge arm is retracted.

[0067] The receiving slot provides a fixed and stable installation position for the hinge arm, preventing the hinge arm from displacement or shaking during use, and can accommodate part of the hinge arm to reduce the overall height of the hinge.

[0068] In an optional embodiment, the guide groove 11 includes a first inner wall and a second inner wall 115 relative to each other, the first inner wall is provided with a first guide rail along the length direction of the guide groove 11 , and the second inner wall 115 is provided with a second guide rail 116 along the length direction of the guide groove 11 .

[0069] A first slider 211 is provided outside the first side plate 21 of the second base 20 , and a second slider is provided outside the second side plate 22 of the second base 20 . The first slider 211 is slidably mounted in the first guide rail, and the second slider is slidably mounted in the second guide rail 116 .

[0070] The first slider 211 cooperates with the first guide rail, and the second slider cooperates with the second guide rail 116 to prevent the second base 20 from tilting or shaking during the sliding process, thereby ensuring that the sliding path of the second base 20 is stable.

[0071] In practical applications, the double guide rails (first guide rail and second guide rail 116) and double sliders (first slider 211 and second slider) can ensure the stability of the hinge arm when sliding, avoid the left and right or up and down deviation of the second base 20, and thus ensure the stability when adjusting the door body.

[0072] Specifically, in this embodiment, the first slider 211 is a rectangular block, and the shape of the second slider can be the same as that of the first slider 211 to maintain smooth sliding.

[0073] The rectangular block has a relatively large contact surface, which can distribute the friction force more evenly and reduce the local wear of the slider.

[0074] In other embodiments, the first slider 211 / the second slider may also be in other shapes, such as circular, elliptical, etc. The first slider 211 may not be provided on the first side plate 21 of the second base 20, but a transverse pulley may be provided to reduce frictional resistance during adjustment and improve the convenience of door adjustment.

[0075] In an optional embodiment, the first base 10 includes two opposite outer walls, each of which is provided with a fixing block 15 , and the fixing block 15 is used to be fixedly connected to the cabinet.

[0076] The fixing block 15 firmly connects the first base 10 to the cabinet body, ensuring the installation stability of the entire sliding hinge cup. The fixing block 15 on the outer wall of the first base 10 allows the first base 10 to withstand the force generated when the window door slides, preventing the first base 10 from loosening or shifting.

[0077] Fixing blocks 15 are provided on both sides of the outer wall of the first base 10 to evenly distribute the forces generated during the sliding of the door. When the door is opened and closed, the lateral and longitudinal forces generated by the fixing blocks 15 are effectively distributed to the cabinet structure, thereby improving the durability and impact resistance of the overall structure.

[0078] Furthermore, in this embodiment, the first base 10 further includes a fixing piece. A fixing hole 151 is formed on the fixing block 15 . The fixing piece is passed through the fixing hole 151 to be fixedly connected to the cabinet.

[0079] The fixing block 15 is physically fixed in depth by the fixing piece, thereby increasing the connection strength. The fixing piece is also easy to disassemble, and is convenient for maintenance or replacement.

[0080] The fixing member can be used in conjunction with a locking washer or a rubber pad to absorb vibrations to the door body during connection and prevent the thread from loosening during long-term use. Specifically, the fixing member can be a bolt, an expansion screw, or the like.

[0081] In an optional embodiment, a first positioning hole 212 is defined on the first side plate 21 , and a second positioning hole 222 is defined on the second side plate 22 . The first positioning hole 212 and the second positioning hole 222 are disposed opposite to each other.

[0082] The modular aluminum window and door ultra-thin hinge also includes a first rotating shaft, which is arranged between the first positioning hole 212 and the second positioning hole 222. The first rotating shaft is also rotatably connected to the hinge arm so that the second base 20 and the hinge arm can rotate based on the axis of the first rotating shaft.

[0083] The first pivot axis distributes the torque and pressure generated during the hinge arm's rotation, ensuring even force distribution during rotation. The stable connection between the locating hole and the pivot axis ensures smooth rotation without causing shaking or structural damage due to uneven force distribution.

[0084] It should be noted that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. are only for the convenience of describing the present application and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present application. The directional terms "inside" and "outside" refer to the inside and outside relative to the outline of the component itself. For example, if the device in the drawing is inverted, the device described as "above other devices or structures" or "on top of other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Therefore, the exemplary term "above..." can include both "above..." and "below..." orientations. The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used here will be interpreted accordingly.

[0085] It should also be noted that references to "one embodiment," "another embodiment," "an embodiment," etc., in this application refer to specific features, structures, or characteristics described in conjunction with that embodiment as included in at least one embodiment generally described in this application. The appearance of the same expression in multiple places in the specification does not necessarily refer to the same embodiment. Furthermore, when a specific feature, structure, or characteristic is described in conjunction with any embodiment, it is intended that such feature, structure, or characteristic, when implemented in conjunction with other embodiments, also fall within the scope of this application.

[0086] In the above embodiments, the description of each embodiment has its own focus. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0087] It should also be noted that the above are only preferred embodiments of the present application and do not limit the scope of patent protection of the present application. Any equivalent structure or equivalent process transformation made using the contents of the description and drawings of this application, or directly or indirectly applied in other related technical fields, are also included in the scope of patent protection of the present application.
