Description

Technical Field

[0001] This utility model relates to the field of hinge technology, and in particular to an adjustable hinge. Background Technology

[0002] To accommodate the normal opening, closing, and sealing performance of doors and windows, hinges, as the core component connecting door (window) frames and door (window) leaves, have an adjustment performance that directly affects the usability of doors and windows. Most hinges on the market today have significant technical limitations: On the one hand, for adjustments perpendicular to the door (window) plane, existing hinges either lack adjustment capabilities altogether or are cumbersome to adjust. When the rubber strips on the door (window) are difficult to compress and deform, the sash plane tends to shift towards the side where the hinge is installed, perpendicular to the frame plane. This damages the overall sealing performance of the door and window, affecting not only the flatness of the appearance but also increasing the operating resistance of the handle when locked, reducing ease of use. On the other hand, most hinges use a non-adjustable pivot structure. When such hinges are used on hinged doors, the door will continuously tilt towards the handle side under its own weight. This tilt not only further exacerbates the decay of sealing performance and deformation of the appearance but can also hinder the normal opening and closing of the door in severe cases, even causing the handle and other operating components to fail, failing to meet the requirements for long-term stable use of doors and windows.

[0003] It is evident that existing technologies still need improvement and enhancement. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of this utility model is to provide an adjustable hinge, which aims to solve the technical problem of non-adjustable hinges in dealing with fan plane offset and gravity tilt.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An adjustable hinge includes a frame edge page, a sash edge page, and a hinge shaft. The frame edge page is fixedly connected to a door frame or window frame, and the sash edge page is fixedly connected to a door leaf or window leaf. The frame edge page is sleeved on one end of the hinge shaft via a frame shaft sleeve, and the sash edge page is sleeved on the other end of the hinge shaft via a sash shaft sleeve, so as to realize the hinge of the frame edge page and the sash edge page through the hinge shaft. The fan-shaped edge page is provided with a first hinge hole and a first adjustment hole. The fan shaft sleeve is movably installed in the first hinge hole. The fan shaft sleeve is fixedly sleeved on one end of the hinge shaft. An adjustment screw is screwed onto the fan shaft sleeve. The first adjustment hole is connected to the first hinge hole and is used to allow a tool to be inserted and turned to adjust the hinge shaft to move along the first radial direction of the hinge shaft in the first hinge hole, thereby realizing the movement of the fan-shaped edge page relative to the frame edge page. A second adjustment hole is provided at the edge of the sash, and an eccentric pin is movably disposed in the second adjustment hole. The eccentric pin is fixedly connected to the sash pressing plate, which is fixedly connected to the door or window sash. By rotating the eccentric pin, the edge of the sash can be adjusted to move relative to the sash pressing plate along the second radial direction of the hinge axis, and the first radial direction is perpendicular to the second radial direction.

[0006] The adjustable hinge has a fan-side leaf with several elongated movable holes, the length of which is the same as the second radial direction. The movable holes are used to accommodate fastening screws, which slide within the movable holes along their length. The fastening screws are screwed to the fan pressure plate to make the fan-side leaf adjustable and fixed relative to the fan pressure plate.

[0007] The adjustable hinge has a square cross-section for the first hinge hole, the width of which is equal to the axial length of the adjusting screw and greater than the width of the fan bushing; the height of the first hinge hole is equal to the height of the fan bushing; and the cross-sectional shape of the fan bushing is square on the outside and round on the inside, to fit the square first hinge hole and fit a circular hinge shaft.

[0008] The adjustable hinge has a second hinge hole on the frame side, and a frame bushing is fixedly installed inside the second hinge hole. The frame bushing is rotatably sleeved on the other end of the hinge shaft.

[0009] The adjustable hinge, wherein the frame edge page is fixedly connected to a frame pressure plate, and the frame pressure plate is fixedly installed in the mounting groove of the door frame or window frame profile.

[0010] The adjustable hinge has a slot at the lower end of the frame edge page, which accommodates the side groove wall at the lower end of the mounting groove of the door or window frame profile. The middle part of the frame edge page abuts against the outside of the side groove wall at the upper end of the mounting groove. The frame edge page and the frame clamping plate cooperate to clamp the frame edge page on the inner and outer sides of the side groove wall of the mounting groove, so as to achieve a fixed connection between the frame edge page and the door or window frame.

[0011] The adjustable hinge comprises two frame edge pages, two hinge shafts, two frame pressure plates, and two frame shaft sleeves. The frame edge pages are located at both ends of the fan edge pages along the length of the hinge shaft. The two ends of the fan shaft sleeves are respectively fixedly sleeved on the ends of the two hinge shafts that are close to each other. The two frame pressure plates are respectively connected to the two frame edge pages one by one. The two frame shaft sleeves are respectively sleeved on the ends of the two hinge shafts that are far from each other.

[0012] The adjustable hinge has a first adjusting hole located at the middle of the fan side leaf along the length of the hinge axis, and an adjusting screw installed at the middle of the fan shaft sleeve along the length of the hinge axis.

[0013] Beneficial effects: This utility model provides an adjustable hinge. By utilizing the movable engagement between the first hinge hole on the fan side panel and the fan shaft sleeve, combined with the adjusting screw screwed to the fan shaft sleeve, the operation of turning the adjusting screw through the first adjusting hole drives the hinge shaft to move along the first radial direction of the hinge shaft, thereby adjusting the position of the fan side panel relative to the frame side panel in that direction. Simultaneously, through the movable adaptation between the second adjusting hole on the fan side panel and the eccentric pin, and relying on the fixed connection between the eccentric pin and the fan pressure plate, rotating the eccentric pin pushes the fan side panel relative to the fan pressure plate along the second radial direction of the hinge shaft. The first and second radial directions are perpendicular to each other, forming a bidirectional adjustment structure covering different adjustment needs. Combined with the stable hinge between the frame side panel and the hinge shaft, the reliability of the overall connection is ensured. This adjustable hinge effectively addresses the technical pain points of existing hinges: For the issue of door panels tilting towards the handle due to gravity, the first radial adjustment precisely corrects the tilting trend of the sash edge panel relative to the frame edge panel, preventing obstruction of door or window opening and closing and operational malfunctions, ensuring long-term stable opening and closing performance. For situations where the door or window panel shifts towards the hinge installation side due to the difficulty in compressing and deforming the rubber strip, the second radial adjustment flexibly adjusts the position of the sash edge panel relative to the sash pressure plate, returning the sash surface to the correct installation position, thereby restoring the sealing performance of the door or window, improving the smoothness of the appearance, reducing the operating resistance of the handle in the locked state, and enhancing ease of use.

To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following describes this utility model in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

Furthermore, "first" and "second" are only for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "multiple" means two or more.

[0018] Please see Figures 1 to 7 As shown, this utility model provides an adjustable hinge, which includes a frame edge page 1, a sash edge page 2, and a hinge shaft 3. The frame edge page 1 is fixedly connected to the door frame or window frame 01, and the sash edge page 2 is fixedly connected to the door leaf or window leaf 02. The frame edge page 1 is sleeved on one end of the hinge shaft 3 through a frame shaft sleeve 4, and the sash edge page 2 is sleeved on the other end of the hinge shaft 3 through a sash shaft sleeve 5, so as to realize the hinge of the frame edge page 1 and the sash edge page 2 through the hinge shaft 3. The fan-shaped edge page 2 is provided with a first hinge hole 21 and a first adjustment hole 22. The fan shaft sleeve 5 is movably installed in the first hinge hole 21. The fan shaft sleeve 5 is fixedly sleeved on one end of the hinge shaft 3. An adjustment screw 6 is screwed onto the fan shaft sleeve 5. The first adjustment hole 22 is connected to the first hinge hole 21 and is used to allow a tool to be inserted and turned to adjust the hinge shaft 3 to move along the first radial direction of the hinge shaft 3 within the first hinge hole 21, thereby realizing the movement of the fan-shaped edge page 2 relative to the frame edge page 1. With the movable cooperation between the first hinge hole 21 on the fan-shaped edge page 2 and the fan shaft sleeve 5, combined with the adjustment screw 6 screwed onto the fan shaft sleeve 5, and by using the operation of inserting a tool into the first adjustment hole 22 to turn the screw, the hinge shaft 3 can be driven to move along the first radial direction of the hinge shaft 3, thereby driving the fan-shaped edge page 2 to achieve position adjustment in this direction relative to the frame edge page 1.

[0019] A second adjustment hole 23 is provided at the leaf of the sash edge 2. An eccentric pin 7 is movably housed in the second adjustment hole 23. The eccentric pin 7 is fixedly connected to a sash pressure plate 8, which is fixedly connected to the door leaf or window leaf 02. By rotating the eccentric pin 7, the sash edge 2 can be adjusted to move relative to the sash pressure plate 8 along the second radial direction of the hinge axis 3, and the first radial direction is perpendicular to the second radial direction. Through the movable adaptation of the second adjustment hole 23 on the leaf of the sash edge 2 and the eccentric pin 7, and relying on the fixed connection between the eccentric pin 7 and the sash pressure plate 8, rotating the eccentric pin 7 can push the sash edge 2 to move relative to the sash pressure plate 8 along the second radial direction of the hinge axis 3, and the first radial direction is perpendicular to the second radial direction, forming a bidirectional adjustment structure that covers different adjustment needs. Combined with the stable hinge of the frame edge 1 and the hinge axis 3, the reliability of the overall connection is ensured.

[0020] Regarding the issue of door panels tilting towards the handle side due to gravity, the first radial adjustment precisely corrects the tilting trend of the sash edge 2 relative to the frame edge 1, preventing obstruction of door or window panel opening and closing and operational malfunction, ensuring long-term stable opening and closing performance of the door or window panel 02. For situations where the door or window panel 02 shifts towards the hinge installation side due to the difficulty in compressing and deforming the rubber strip, the second radial adjustment flexibly adjusts the position of the sash edge 2 relative to the sash pressure plate 8, returning the sash surface to the correct installation position, thereby restoring the sealing performance of the door or window, improving the appearance flatness, and reducing the operating resistance of the handle in the locked state, enhancing ease of use. Furthermore, the entire adjustment process requires no complex disassembly; it can be completed simply by inserting a tool into the adjustment hole. Compared to existing hinges that are difficult or impossible to adjust, this significantly simplifies the adjustment process. The bidirectional vertical adjustment design simultaneously covers both tilt correction and plane offset adjustment, filling the technical gap in existing hinges that struggle to accommodate multi-directional adjustment, comprehensively improving the user experience and durability of doors or windows.

[0021] In this embodiment, the frame edge 1 and the sash edge 2 are made of 6061-T6 aluminum alloy, the hinge shaft 3 is made of 304 stainless steel, and the adjusting screw 6 is an M8*16 hexagonal socket head cap screw. After testing, the maximum load-bearing capacity of the hinge is 200kg, which is suitable for standard European standard 20 groove aluminum alloy doors and windows. The head 71 and tail 72 of the eccentric nail 7 are coaxial, and the central axis is offset from the axes of the head 71 and tail 72 to form an eccentric part 73. The eccentric part 73 is housed in the second adjustment hole 23, and the tail 72 is riveted to the sash plate 8. The cross-sectional shape of the second adjustment hole 23 is rectangular. The width of the rectangle is equal to the diameter of the eccentric part 73, and the length of the rectangle is greater than the diameter of the eccentric part 73. The length direction of the rectangle is the same as the length direction of the hinge shaft 3. The shape design of the second adjustment hole 23 can counteract the movement of the sash edge 2 relative to the sash plate 8 along the length direction of the hinge shaft 3 when the eccentric nail 7 rotates, so that when the eccentric nail 7 rotates, the sash edge 2 can only move relative to the sash plate 8 along the second radial direction of the hinge shaft 3 for adjustment. This adjustable hinge can achieve an adjustment distance of 1.5 mm in the first radial direction and 1.00 mm in the second radial direction, allowing for fine adjustment of the installation of doors and windows.

[0022] Please see Figure 1 and Figure 5 As shown, the fan-shaped edge page 2 has several elongated movable holes 24, the length direction of which is the same as the second radial direction. The movable holes 24 are used to accommodate fastening screws 25, which slide within the holes along their length. The fastening screws 25 are screwed to the fan pressure plate 8 to achieve both adjustment and fixation of the fan-shaped edge page 2 relative to the fan pressure plate 8. In this embodiment, there are four movable holes 24, arranged in pairs on both sides of the second adjustment hole 23, forming a straight line with the second adjustment hole 23 along the axis of the hinge shaft 3. The fastening screws 25 are hexagonal pan head screws, with one screw 25 accommodated in each movable hole 24. The fan pressure plate 8 has threaded holes corresponding to the movable holes 24 for screwing the fastening screws 25. When the eccentric nail 7 is rotated, the eccentric part 73 pushes against the inner wall of the second adjustment hole 23, causing the fan edge 2 to move relative to the fan pressure plate 8. Due to the structural design of the second adjustment hole 23 and the movable hole 24, the fan edge 2 can only move relative to the fan pressure plate 8 along the length direction of the movable hole 24, that is, the adjustment of the fan edge 2 in the second radial direction is realized.

[0023] Please see Figure 1 and Figure 4As shown, the cross-section of the first hinge hole 21 is square, and its width is equal to the axial length of the adjusting screw 6 and greater than the width of the fan bushing 5; the height of the first hinge hole 21 is equal to the height of the fan bushing 5; the cross-sectional shape of the fan bushing 5 is square on the outside and round on the inside, to fit the square first hinge hole 21 and to fit the circular hinge shaft 3. In this embodiment, the first hinge hole 21 penetrates the fan side 2 along the length direction of the fan side 2, and the two long side walls of the first hinge hole 21 abut against the upper and lower sides of the fan bushing 5 respectively. The adjusting screw 6 penetrates from one end face of the fan bushing 5 in the width direction to the other end face, and the two ends of the adjusting screw 6 abut against the two short side walls of the first hinge hole 21 respectively. The internal hexagonal hole of the adjusting screw 6 is concentrically set with the second adjusting hole 23; one end of the hinge shaft 3 is fixed to the fan bushing 5 by stamping. When the adjusting screw 6 is turned with a hex key, the adjusting screw 6 is equivalent to a lead screw, and the fan shaft sleeve 5 is equivalent to a lead screw nut. It moves along the axial direction of the adjusting screw 6 in the first hinge hole 21, thereby driving the hinge shaft 3 to move. Finally, it drives the frame edge 1 to move relative to the fan edge 2 along the first radial direction, solving the problem of the door leaf tilting towards the handle side due to gravity.

[0024] Please see Figures 1 to 2 As shown, the frame leaf 1 is provided with a second hinge hole 11, and a frame bushing 4 is fixedly installed inside the second hinge hole 11. The frame bushing 4 is rotatably sleeved on the other end of the hinge shaft 3. In this embodiment, the inner wall of the second hinge hole 11 is provided with a limiting groove, and the outer side of the frame bushing 4 is provided with a protruding limiting strip. The limiting strip is installed in the limiting groove to limit the rotation of the frame bushing 4 relative to the frame leaf 1. By rotatably sleeved on the other end of the hinge shaft 3, the frame leaf 1 is prevented from directly contacting the hinge shaft 3 and causing rotational wear, which is beneficial to improving the service life of the hinge.

[0025] Please see Figure 1 and Figure 7 As shown, the frame edge page 1 is fixedly connected to a frame pressure plate 9, which is fixedly installed in the mounting groove 03 of the door or window frame 01 profile. In this embodiment, a countersunk hole and two connecting holes are provided through the frame edge page 1. The two connecting holes are located on both sides of the countersunk hole and are arranged in a straight line along the axial direction of the hinge shaft 3. The frame pressure plate 9 is provided with three threaded holes. The countersunk hole is used to install Phillips head countersunk screws, and the connecting holes are used to install hexagonal pan head screws. The Phillips head countersunk screws and the two hexagonal pan head screws are screwed into the three threaded holes to achieve a fixed connection between the frame edge page 1 and the frame pressure plate 9. The mounting groove 03 of the door or window frame 01 profile has its upper and lower ends protruding inward to form side groove walls parallel to the bottom wall. The frame pressure plate 9 is accommodated in the mounting groove 03, with its upper end abutting against the side groove wall at the upper end of the mounting groove 03, and its lower end abutting against the lower end of the frame edge page 1.

[0026] Please see Figure 1 and Figure 7As shown, the lower end of the hinge panel 1 has a slot 12. The slot 12 accommodates the side wall of the mounting groove 03 at the lower end of the door or window frame 01 profile. The middle part of the hinge panel 1 abuts against the side wall of the upper end of the mounting groove 03. The hinge panel 1 and the frame clamping plate 9 cooperate to clamp the hinge panel 1 on the inner and outer sides of the side wall of the mounting groove 03, thereby achieving a fixed connection between the hinge panel 1 and the door or window frame 01. In this embodiment, the width of the slot 12 is greater than or equal to the thickness of the side wall at the lower end of the mounting groove 03. The hinge panel 1 and the door or window frame 01 profile form a snap-fit ​​connection structure. The frame clamping plate 9 is then configured to further abut and fix the hinge, improving the connection stability and reliability between the hinge and the door or window frame 01 profile.

[0027] Please see Figures 1 to 3 As shown, there are two of each of the following components: frame side panel 1, hinge shaft 3, frame pressure plate 9, and frame shaft sleeve 4. The frame side panel 1 is located at both ends of the fan side panel 2 along the length of the hinge shaft 3. The two ends of the fan shaft sleeve 5 are respectively fixedly fitted onto the ends of the two hinge shafts 3 that are close to each other. The two frame pressure plates 9 are respectively connected to the two frame side panels 1 in a one-to-one correspondence. The two frame shaft sleeves 4 are respectively fitted onto the ends of the two hinge shafts 3 that are far from each other. In this embodiment, the two frame side panels 1 are positioned at both ends of the fan side panel 2 to form a symmetrical and balanced three-wing hinge structure. From a stress perspective, the cooperation between the double hinge shaft 3 and the double frame edge 1 effectively disperses the weight of the door or window sash 02 and the forces exerted during opening and closing, preventing deformation or wear of the hinge components caused by concentrated stress in the single-axis, single-frame edge 1 structure. This prevents the door sash from tilting towards the handle due to gravity, ensuring long-term stable opening and closing function and reducing the impact on sealing and appearance. In terms of connection stability, the double frame pressure plate 9 and the double frame shaft sleeve 4 respectively enhance the connection reliability between the frame edge 1 and the door or window frame 01, and between the frame edge 1 and the hinge shaft 3. This design reduces the probability of hinge loosening after long-term use and further maintains the relative positional accuracy between the frame and the sash. In addition, the symmetrical structural design makes the overall force on the hinge more even. When the sash edge 2 is adjusted along the first or second radial direction, it is not easy to shift due to force imbalance, ensuring that the sash plane can accurately return to the preset position after adjustment. At the same time, it adapts to the overall structural requirements of the three-wing hinge, ensuring the load-bearing capacity of the hinge while taking into account the structural compactness, avoiding the hinge occupying too much installation space, and improving the compatibility with doors and windows of different specifications.

[0028] Please see Figures 1 to 2As shown, the first adjustment hole 22 is located at the middle position of the fan side page 2 along the length of the hinge shaft 3, and the adjustment screw 6 is installed at the middle position of the fan shaft sleeve 5 along the length of the hinge shaft 3. In terms of operational convenience, the middle position provides a more reasonable operating space for the tool to enter the first adjustment hole 22, eliminating the need to avoid the frame side pages 1 or other components at both ends of the hinge, reducing space limitations during tool operation, and allowing users to quickly find the adjustment position without complex positioning, effectively solving the problem of difficult adjustment processes in existing hinges. Regarding the uniformity and accuracy of adjustment, the centrally located adjustment screw 6 ensures that the force exerted on the fan shaft sleeve 5 when turning the adjustment screw 6 is evenly transmitted to the entire fan shaft sleeve 5, preventing tilting due to uneven force on the fan shaft sleeve 5 caused by the offset adjustment screw 6, and ensuring that the hinge shaft 3 along the length of the first adjustment hole 22 is evenly distributed. The radial movement is smooth and without jamming, making the adjustment of the sash edge 2 relative to the frame edge 1 smoother and allowing for precise control of the adjustment amount. At the same time, the first adjustment hole 22 in the middle of the sash edge 2 corresponds to the adjustment screw 6 in the middle of the sash bushing 5. The adjustment force can be directly applied to the force center of the sash edge 2 and the sash bushing 5, making the adjustment action more direct and effective in changing the position of the sash edge 2, reducing force loss during the adjustment process, and achieving precise positioning of the sash edge 2 without repeated adjustments. This further ensures the optimized effect of the door or window sash 02 in terms of sealing performance, appearance flatness, and handle operation force after adjustment.
