Description

Technical Field

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

[0002] Hinges, as mechanical devices that connect two components and allow relative rotation between them, are widely used in various products such as doors and windows, furniture, and industrial equipment. Their performance directly affects the assembly accuracy, stability, and service life of the components. In actual production and installation, traditional fixed-structure hinges often face many application challenges due to factors such as processing errors (e.g., component size deviations, mounting hole offsets), limitations in assembly operation accuracy, and changes in the usage environment (e.g., component deformation caused by temperature and humidity).

[0003] Most hinges on the market are currently designed as a single, fixed unit. Their connection positions and assembly gaps are fixed at the factory, only meeting standardized assembly requirements. When misalignment occurs in components such as doors, windows, or furniture, operators cannot compensate for the deviation by adjusting the hinge itself. They can only correct it by forcibly adjusting the component's position, adding extra shims, or re-drilling holes. This not only increases installation time and difficulty but may also cause irreversible damage to the components, reducing the overall assembly quality of the product.

[0004] Therefore, an adjustable hinge needs to be designed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an adjustable hinge. This invention has the advantages of comprehensive adjustment dimensions, simple operation, and stable locking. It can effectively compensate for deviations in component processing and assembly, improve installation efficiency and assembly quality, and meet the usage needs of different scenarios.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An adjustable hinge includes a mother page and a daughter page, which are connected by a lateral adjustment assembly. The lateral adjustment assembly includes an adjustment plate located on the front side of the mother page. The adjustment plate has a horizontally arranged strip-shaped opening, through which a locking bolt passes. Two sleeves are fixedly connected to the right side of the adjustment plate, and a rotating rod is rotatably connected to both sleeves. The left side of the daughter page is fixedly connected to the rotating rod.

[0007] Preferably, the master page is provided with a vertical adjustment component, the vertical adjustment component includes a sliding groove provided on the front side of the master page, a slider is slidably connected in the sliding groove, the slider is provided with a threaded hole, and the locking bolt is threadedly connected to the inner wall of the threaded hole.

[0008] Preferably, the slider is provided with a locking assembly, which includes a rectangular groove disposed on the rear side of the slider, a threaded hole passing through the rectangular groove, two push blocks and an insertion block slidably connected in the rectangular groove, two mating push blocks and an insertion block having a connecting rod fixedly connected to their adjacent sides, two fixing blocks fixedly connected in the rectangular groove, two connecting rods passing through the fixing blocks, two push blocks being elastically connected to the adjacent sides of their corresponding fixing blocks by springs, and multiple insertion slots that mate with the insertion blocks being provided on the inner walls of the left and right sides of the sliding groove.

[0009] Preferably, the opposite sides of the two push blocks are both curved surfaces.

[0010] Preferably, both the sliding groove and the slider have trapezoidal cross-sections.

[0011] Preferably, both the mother page and the child page are provided with multiple mounting holes, which are located at the four corners of the mother page and the child page, respectively.

[0012] Preferably, the edges of both the mother page and the child page are rounded with a radius of 0.5-1mm.

[0013] Preferably, the inner wall of the sliding groove is coated with a wear-resistant coating, which is a polytetrafluoroethylene coating.

[0014] Compared with existing technologies, the advantages of this device are: 1. Compared with existing technologies, this device achieves multi-dimensional precise adjustment, effectively solving the problem of the single adjustment dimension of traditional hinges. Through the coordinated operation of the horizontal and vertical adjustment components, the device can achieve bidirectional adjustment in both the horizontal and vertical directions: the strip opening of the adjustment plate in the horizontal adjustment component provides sufficient travel for horizontal position compensation; the vertical adjustment component utilizes the sliding cooperation between the slider and the sliding groove to provide stable support for vertical position correction. This bidirectional adjustment capability can comprehensively compensate for multi-directional deviations that occur during component processing and assembly, significantly improving assembly accuracy and adaptability. 2. Compared with existing technologies, this device is simple and efficient to adjust, reducing the barriers to installation and maintenance. For horizontal adjustment, simply loosen the locking bolts and push the adjusting plate to move the sub-pages to adjust their horizontal position. After adjustment, retighten the bolts to complete the fixation. Vertical adjustment is achieved by the sliding of the slider within the sliding groove. Furthermore, the arc-shaped design of the push block in the locking assembly allows the insertion block to automatically engage with the insertion groove during the tightening of the locking bolts, eliminating the need for additional tools. This simplifies the operation process, shortens installation time, and allows even non-professionals to quickly complete the adjustment. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Reference Figures 1-4 An adjustable hinge includes a mother hinge 1 and a child hinge 3. The edges of both the mother hinge 1 and the child hinge 3 are rounded with a radius of 0.5-1mm. Both the mother hinge 1 and the child hinge 3 are made of high-strength metal, possessing good structural rigidity and wear resistance, capable of withstanding repeated forces during the opening and closing process of the moving parts, avoiding deformation and damage after long-term use. Both the mother hinge 1 and the child hinge 3 have multiple mounting holes with a countersunk hole design, allowing the head of the mounting bolt to be fully embedded in the hole, preventing the bolt head from protruding and affecting the fit and appearance of the hinge and the moving parts. To ensure neatness and stability after installation, multiple mounting holes are located at the four corners of the mother page 1 and the child page 3. The mother page 1 and the child page 3 are connected by a horizontal adjustment assembly, which includes an adjustment plate 2. The adjustment plate 2 is located on the front side of the mother page 1. The adjustment plate 2 has a horizontally arranged strip-shaped opening 6, and a locking bolt 7 passes through the strip-shaped opening 6. The strip-shaped opening 6 is a countersunk opening structure. After locking, the locking bolt 7 will be completely located inside the strip-shaped opening 6. Two sleeves 4 are fixedly connected to the right side of the adjustment plate 2. A rotating rod 5 is rotatably connected to both sleeves 4. The left side of the child page 3 is fixedly connected to the rotating rod 5.

[0019] The mother page 1 includes a vertical adjustment assembly, which comprises a sliding groove 15 located on the front side of the mother page 1. A slider 8 is slidably connected within the sliding groove 15. The slider 8 has a threaded hole 9, and a locking bolt 7 is threadedly connected to the inner wall of the threaded hole 9. The slider 8 also has a locking assembly, which includes a rectangular groove 11 located on the rear side of the slider 8. The threaded hole 9 passes through the rectangular groove 11, and two push blocks 13 and an insertion block 10 are slidably connected within the rectangular groove 11. Both push blocks 13 and insertion blocks 10 are made of wear-resistant engineering plastic to reduce wear during sliding and extend the service life of the assembly. A connecting rod 12 is fixedly connected to the adjacent sides of the two mating push blocks 13 and insertion blocks 10. Two fixing blocks are fixedly connected within the rectangular groove 11, and the two connecting rods 12 pass through the fixing blocks. The fixing blocks have guide holes that mate with the connecting rods 12, providing guidance for the sliding of the connecting rods 12 and ensuring the direction of movement. For precision, the two push blocks 13 are elastically connected to the adjacent sides of the corresponding fixed blocks by springs 14. The inner walls of the left and right sides of the sliding groove 15 are provided with multiple insertion slots 16 that cooperate with the insertion blocks 10. The multiple insertion slots 16 are distributed at equal intervals along the vertical direction of the sliding groove 15. The spacing between adjacent insertion slots 16 is set according to the adjustment precision requirements to achieve graded adjustment of the vertical position. The opposite sides of the two push blocks 13 are both arc surfaces. The arc surface structure design allows the head of the locking bolt 7 to generate a lateral force through the arc surface when tightened, pushing the push blocks 13 to move to both sides. The insertion blocks 10 can be extended and locked without additional operation. The cross-sections of the sliding groove 15 and the slider 8 are both trapezoidal. The inner wall of the sliding groove 15 is coated with a wear-resistant coating, which is a polytetrafluoroethylene coating. The trapezoidal structure has a good anti-disengagement effect, which can prevent the slider 8 from shifting laterally during vertical sliding, while increasing the contact area between the two and improving the load-bearing capacity.

[0020] The functional principle of this utility model can be explained through the following operation: During the assembly stage, the mother page 1 is fixed to fixed components such as door frames and window frames through the mounting holes at the four corners of the mother page 1 and the child page 3, and the child page 3 is fixed to movable components such as door bodies and window sashes. After assembly, the child page 3 is rotatably connected to the right sleeve 4 of the adjusting plate 2 through the rotating rod 5, and can rotate flexibly around the axis of the rotating rod 5, thereby realizing the opening and closing action of the movable component relative to the fixed component, and meeting the basic usage requirements of the hinge.

[0021] When it is necessary to adjust the lateral distance between the moving component and the fixed component, first loosen the locking bolt 7 that passes through the strip opening 6 of the adjusting plate 2. At this time, the adjusting plate 2 is released from the fixed constraint of the slider 8 on the mother page 1. Since the strip opening 6 is set in the lateral direction, pushing the adjusting plate 2 can make it move freely in the lateral direction. The adjusting plate 2 drives the daughter page 3 to move laterally in sync through the sleeve 4 and the rotating rod 5. After adjusting to the target position, tighten the locking bolt 7 again so that the locking bolt 7 and the threaded hole 9 of the slider 8 are tightly engaged, fixing the adjusting plate 2 and the slider 8, thereby locking the lateral position of the daughter page 3 and completing the lateral adjustment.

[0022] When adjusting the vertical position, first loosen the locking bolt 7 to release the slider 8 from the fixing of the adjusting plate 2. Since the slider 8 and the sliding groove 15 of the mother page 1 form a sliding fit, and both have trapezoidal cross sections, pushing the slider 8 can make it slide vertically along the sliding groove 15. The slider 8 drives the adjusting plate 2 and the daughter page 3 to move vertically synchronously through the locking bolt 7. During the sliding of the slider 8, the push block 13 of the locking component is subjected to the elastic force of the spring 14, which drives the insertion block 10 to keep in a retracted state to avoid interference with the inner wall of the sliding groove 15. After adjusting to the target position, tighten the locking bolt 7. During the tightening process, the bolt squeezes the arc surface of the push block 13, forcing the push block 13 to drive the insertion block 10 to extend to both sides and get into the corresponding insertion groove 16 on the inner wall of the sliding groove 15 to form a vertical fixation. At the same time, the cooperation between the locking bolt 7 and the threaded hole 9 achieves secondary fixation, completing the vertical adjustment and double locking.

[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
