Abstract
Description
Technical Field
[0001] This utility model relates to the field of door and window accessories technology, and in particular to a multi-dimensional adjustable hinge. Background Technology
[0002] Hinges, as the most important component of swing doors, are responsible for all weight-bearing and opening functions. Over time, hinges can loosen, causing errors in the gap between the door leaf and the frame. This often requires disassembling the door leaf to adjust the gap, which is inconvenient and cumbersome. While some hinges now have adjustable functions, allowing adjustment without disassembling the door, existing hinge adjustment mechanisms are usually quite complex. This means installers often need to repeatedly adjust the hinges to ensure the door leaf and frame are as flat as possible, minimize the gap between them, and precisely control the door leaf's distance from the ground after installation. These adjustments are often time-consuming and inefficient. The complexity of the structure also leads to higher costs and lower reliability for adjustable hinges.
[0003] The technical problem to be solved by this utility model is: how to provide a hinge with a simple structure and convenient adjustment. Utility Model Content
[0004] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a multi-dimensional adjustable hinge, which has the characteristics of simple structure and convenient adjustment.
[0005] The technical solution adopted by this utility model is as follows: a multi-dimensional adjustable hinge, including a pivot, an upper page and a lower page arranged from top to bottom on the pivot, the pivot including a first shaft and a second shaft connected in sequence, the first shaft and the second shaft being eccentrically arranged, the upper page having a first shaft hole that is rotatably engaged with the first shaft, the lower page having a second shaft hole that is rotatably engaged with the second shaft hole, and further including an anti-rotation member for limiting the relative rotation between the second shaft and the second shaft hole and an adjustment member for limiting the insertion depth of the second shaft into the second shaft hole, the anti-rotation member being disposed on one side of the second shaft hole and threadedly connected to the lower page, the adjustment member being disposed at the end of the second shaft hole away from the first shaft and threadedly connected to the lower page.
[0006] This application's multi-dimensional adjustable hinge allows for fine-tuning in both left-right and up-down directions, featuring a simple structure and convenient adjustment. The first and second shafts are eccentrically positioned, allowing adjustment of the radial (left-right) relative position of the upper and lower blades by rotating the shafts. After adjustment, a locking element secures the lower blade to the second shaft, preventing relative rotation and ensuring the radial position of the upper and lower blades is maintained. An adjusting element at the lower end of the lower blade allows adjustment of the axial (up-down) relative position of the lower and upper blades by adjusting the depth of its insertion into the second shaft hole, providing convenient and quick adjustment.
[0007] In some embodiments, the adjusting member is provided with an up-and-down adjusting groove.
[0008] By adopting the above technical solution, by opening the upper and lower adjustment grooves on the adjustment component, it is easy to rotate the adjustment component with the help of tools, thereby adjusting the relative height of the upper and lower pages.
[0009] In some embodiments, the end of the second shaft away from the first shaft is provided with a left-right adjustment groove, and the adjustment component is provided with a through clearance groove, which corresponds to the left-right adjustment groove.
[0010] By adopting the above technical solution, by opening left and right adjustment slots on the second shaft, it is convenient to rotate the shaft with tools to adjust the radial relative position of the upper and lower blades. By opening clearance slots on the adjustment component, it is convenient for the tool to pass through the adjustment component and connect with the left and right adjustment slots, thus avoiding interference of the adjustment component with the radial adjustment.
[0011] In some implementations, the clearance groove is connected to the upper and lower adjustment grooves.
[0012] In some embodiments, an anti-reverse component is also included to restrict the rotation of the adjusting member. The anti-reverse component is threadedly connected to the lower page and is disposed on one side of the adjusting member.
[0013] By adopting the above technical solution, the anti-reverse component can prevent the adjusting component from rotating after the relative height of the upper and lower pages has been adjusted, thus playing a safety role.
[0014] In some embodiments, the lower page includes a second mounting plate and a second sleeve, the second sleeve being connected to one side of the second mounting plate, a second shaft hole being disposed on the second sleeve, and an anti-reverse component, an anti-rotation component, and an adjusting component being disposed on the second sleeve.
[0015] In some embodiments, the anti-reverse component and the anti-rotation component are disposed on the side of the second sleeve away from the second mounting plate.
[0016] The above technical solution is more aesthetically pleasing and also facilitates the operation of the anti-reverse and anti-rotation components.
[0017] In some embodiments, the rotating shaft further includes a connecting shaft disposed between the first shaft and the second shaft, the outer diameter of the connecting shaft being larger than the outer diameters of the first shaft and the second shaft.
[0018] Using the above technical solution, the connecting shaft can support the upper page and prevent the upper page from directly contacting the lower page. The outer diameter of the connecting shaft is larger than that of the first shaft and the second shaft, which can accommodate the eccentricity of the first shaft and the second shaft.
[0019] In some embodiments, the first shaft is eccentrically positioned relative to the connecting shaft, while the second shaft is coaxially positioned relative to the connecting shaft.
[0020] In some implementations, the outer diameter of the first shaft is smaller than the outer diameter of the second shaft.
[0021] By adopting the above technical solution, the misalignment between the top and bottom pages can be reduced, resulting in a more aesthetically pleasing appearance. Attached Figure Description

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0031] Please see Figures 1 to 5A preferred embodiment of the present invention provides a multidimensional adjustable hinge 100, comprising a pivot 10, an upper page 20 and a lower page 30 disposed on the pivot 10 from top to bottom. The pivot 10 includes a first shaft 11 and a second shaft 12 connected in sequence, the first shaft 11 and the second shaft 12 being eccentrically disposed. The upper page 20 is provided with a first shaft hole 21, the first shaft hole 21 being rotatably engaged with the first shaft 11. The lower page 30 is provided with a second shaft hole 31, the second shaft 12 being rotatably engaged with the second shaft hole 31. The hinge also includes an anti-rotation member 40 for limiting the relative rotation between the second shaft 12 and the second shaft hole 31, and an adjusting member 50 for limiting the depth of the second shaft 12 inserted into the second shaft hole 31. The anti-rotation member 40 is disposed on one side of the second shaft hole 31 and is threadedly connected to the lower page 30. The adjusting member 50 is disposed at the end of the second shaft hole 31 away from the first shaft 11 and is threadedly connected to the lower page 30. The multidimensional adjustable hinge 100 of this application can be finely adjusted in the left-right and up-down directions, and features a simple structure and convenient adjustment. The first shaft 11 and the second shaft 12 are eccentrically positioned. By rotating the rotating shaft 10, the relative position of the upper leaf 20 and the lower leaf 30 in the radial (left-right) direction can be adjusted. After adjustment, the lower leaf 30 and the second shaft 12 can be locked by the anti-rotation component 40 to prevent relative rotation between the lower leaf 30 and the second shaft 12, ensuring that the radial position of the upper leaf 20 and the lower leaf is maintained. An adjusting component 50 is provided at the lower end of the lower leaf 30. Adjusting the depth of the adjusting component 50 screwed into the second shaft hole 31 can adjust the relative position of the lower leaf 30 and the upper leaf 20 in the axial (up-down) direction, making adjustment convenient and quick.
[0032] like Figure 2 and Figure 5 As shown, to facilitate rotation of the adjusting member 50, a vertical adjustment groove 51 is provided on the adjusting member 50. By providing the vertical adjustment groove 51 on the adjusting member 50, it is easy to rotate the adjusting member 50 with the aid of a tool, thereby adjusting the relative height of the upper page 20 and the lower page 30. In this embodiment, the vertical adjustment groove 51 is hexagonal in shape, and the tool required for vertical adjustment is a hexagonal wrench. It should be noted that the shape of the vertical adjustment groove 51 is not limited to hexagonal; the shape of the vertical adjustment groove 51 can match the tool it is adapted to. The vertical adjustment groove 51 can also be a cross shape, a straight line shape, or other reasonable shapes. Correspondingly, the tool used for vertical adjustment is adapted to the vertical adjustment groove 51.
[0033] Similarly, the end of the second shaft 12 furthest from the first shaft 11 is provided with a left-right adjustment groove 121, and the adjusting member 50 is provided with a through clearance groove 52, which corresponds to the left-right adjustment groove 121. By providing the left-right adjustment groove 121 on the second shaft 12, it is convenient to rotate the shaft 10 with a tool to adjust the radial relative position of the upper blade 20 and the lower blade 30. By providing the clearance groove 52 on the adjusting member 50, it is convenient for the tool to pass through the adjusting member 50 and engage with the left-right adjustment groove 121, avoiding interference of the adjusting member 50 with the radial adjustment.
[0034] Preferably, the clearance groove 52 is connected to the upper and lower adjustment groove 51. In order to avoid the clearance groove 52 interfering with the shape of the upper and lower adjustment groove 51 and to facilitate the operation of left and right adjustment, the diameter of the clearance groove 52 is larger than the diameter of the left and right adjustment groove 121 and smaller than the diameter of the upper and lower adjustment groove 51.
[0035] Preferably, the adjusting member 50, the clearance groove 52, and the upper and lower adjusting grooves 51 are coaxially arranged.
[0036] like Figure 3 and Figure 4 As shown, the left-right adjustment slot 121 is hexagonal, and the tool used for up-down adjustment is a hexagonal wrench. It should be noted that the shape of the left-right adjustment slot 121 is not limited to hexagonal. The shape of the left-right adjustment slot 121 matches the tool it is adapted to. The left-right adjustment slot 121 can also be a cross shape, a straight line shape, or other reasonable shapes. Correspondingly, the tool used for left-right adjustment is adapted to the up-down adjustment slot 51.
[0037] In one embodiment, to prevent the adjusting member 50 from rotating during use after adjustment, the multidimensional adjustable hinge 100 of this application further includes an anti-reverse member 60 to restrict the rotation of the adjusting member 50. The anti-reverse member 60 is threadedly connected to the lower page 30 and is disposed on one side of the adjusting member 50. The anti-reverse member 60 can prevent the adjusting member 50 from rotating after the relative height of the upper page 20 and the lower page 30 has been adjusted, thus serving a safety function.
[0038] Preferably, to ensure the effectiveness of the vertical adjustment, the top of the adjusting member 50 is kept in contact with the bottom of the second shaft 12.
[0039] Specifically, the outer peripheral surface of the adjusting member 50 is provided with external threads, and the inner wall of the second shaft hole 31 is provided with internal threads that engage with it.
[0040] like Figure 1As shown, the upper page 20 includes a first mounting plate 22 and a first sleeve 23. The first sleeve 23 is connected to one side of the first mounting plate 22, and a first shaft hole 21 is provided on the first sleeve 23. Similarly, the lower page 30 includes a second mounting plate 32 and a second sleeve 33. The second sleeve 33 is connected to one side of the second mounting plate 32, and a second shaft hole 31 is provided on the second sleeve 33. Mounting holes for fasteners to pass through are provided on the first mounting plate 22 and the second mounting plate 32.
[0041] Preferably, the anti-reverse component 60, the anti-rotation component 40, and the adjusting component 50 are disposed on the second sleeve 33. Further, the anti-reverse component 60 and the anti-rotation component 40 are disposed on the side of the second sleeve 33 away from the second mounting plate 32. This arrangement is more aesthetically pleasing and facilitates the operation of turning the anti-reverse component 60 and the anti-rotation component 40.
[0042] In one embodiment, the rotating shaft 10 further includes a connecting shaft 13 disposed between the first shaft 11 and the second shaft 12. The outer diameter of the connecting shaft 13 is larger than the outer diameters of the first shaft 11 and the second shaft 12. The connecting shaft 13 can support the upper page 20 and separate the upper page 20 and the lower page 30, preventing direct contact between the upper page 20 and the lower page 30. Since the outer diameter of the connecting shaft 13 is larger than that of the first shaft 11 and the second shaft 12, it can accommodate the eccentricity of the first shaft 11 and the second shaft 12.
[0043] Furthermore, the first shaft 11 is eccentrically positioned with respect to the connecting shaft 13, while the second shaft 12 is coaxially positioned with respect to the connecting shaft 13.
[0044] Furthermore, the outer diameter of the first shaft 11 is smaller than the outer diameter of the second shaft 12. This reduces the misalignment between the upper page 20 and the lower page 30, resulting in a more aesthetically pleasing appearance.
[0045] Optionally, the anti-rotation component 40 and the anti-reverse component 60 are headless screws.
[0046] When adjusting the relative left and right positions of the upper page 20 and the lower page 30, first loosen the anti-rotation piece 40 to separate it from the second shaft 12. Then, use a left-right adjustment tool to pass through the adjustment piece 50 and insert it into the left-right adjustment slot 121 to rotate the shaft 10. After the position is adjusted, remove the left-right adjustment tool and tighten the anti-rotation piece 40 so that it abuts against the second shaft 12, preventing the second shaft 12 from rotating relative to the lower page 30. When adjusting the relative height of the upper page 20 and the lower page 30, first slightly loosen the anti-rotation piece 40, then loosen the anti-reverse piece 60 to separate it from the adjustment piece 50. Then, use an up-down adjustment tool to insert it into the up-down adjustment slot 51 and adjust the depth of the adjustment piece 50 screwed into the second shaft hole 31, thereby adjusting the relative height of the upper page 20 and the lower page 30. After the height is adjusted, remove the up-down adjustment tool and tighten the anti-rotation piece 40 and the anti-reverse piece 60.
[0047] Finally, it should be noted that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
