Description

Technical Field

[0001] This utility model relates to a hinge, specifically a multi-dimensional adjustable hardware hinge. Background Technology

[0002] Hinges are indispensable components in furniture, home appliances, and other fields. Their main function is to connect two adjacent parts and allow controlled rotation between them to meet the opening and closing needs of daily use. Especially in cabinet doors, room doors, and other similar devices, the adjustability, load-bearing capacity, and ease of installation of hinges directly affect their performance.

[0003] Currently, common hardware hinges on the market can be broadly divided into two categories: fixed hinges, which cannot be adjusted after installation, and adjustable hinges. These adjustable hinges allow for adjustment of the door panel position within a certain range after installation, addressing issues caused by door panel misalignment or installation errors. However, existing adjustable hinges still have the following limitations:

[0004] 1. Limited adjustment direction, making it difficult to meet the needs of multi-dimensional position adjustment: Existing hinges typically only support adjustment in a single direction, such as horizontal or vertical adjustment, and cannot achieve comprehensive adjustment in multiple dimensions, such as horizontal, vertical, or other angles. This limitation of single-direction adjustment makes it difficult to make precise adjustments when facing complex installation environments, thus affecting the overall performance of the device.

[0005] 2. Insufficient adjustment precision, making it difficult to meet high-standard installation requirements: Most existing adjustable hinges use screw adjustment, changing the position of the hinge connecting parts by rotating the screw. However, the precision of this adjustment method is usually limited by the thread pitch and the stability of the adjuster. Especially after multiple adjustments, the connecting parts may loosen or shift, thus reducing the reliability and precision of the adjustment.

[0006] The complex structural design makes installation and maintenance difficult. To achieve multiple adjustment functions, existing adjustable hinges typically require intricate adjustment mechanisms. These complex structures not only increase manufacturing costs and assembly difficulty but also raise the learning curve for users during installation and use. Furthermore, due to the large number of components in the complex structure, the hinges are prone to wear or loosening after prolonged use, making subsequent maintenance even more challenging.

[0007] 3. Insufficient load-bearing capacity and short service life: In some existing hinge technologies, in order to achieve lightweight and convenience, core components such as adjustment grooves and guide blocks are often made of weak materials or have simplified designs. While this design can reduce manufacturing costs, it significantly reduces the load-bearing capacity of the hinge, making it prone to breakage or deformation, especially under frequent opening and closing or heavy-load scenarios, thus affecting its service life. Therefore, further improvements are necessary. Utility Model Content

A transverse adjustment device is provided between the hinge arm and the transfer plate to drive the relative transverse displacement of the two.

[0012] It also includes a base plate, on which a vertical guide groove is provided, and a vertical guide block is provided on the transfer plate. The vertical guide block is slidably installed in the vertical guide groove to realize the connection between the base plate and the transfer plate. A vertical adjustment device is provided between the base plate and the transfer plate to drive the relative vertical displacement between the two.

[0013] Furthermore, the transfer plate has connecting plates bent upwards on both its upper and lower sides, and the lateral guide block is disposed on the outer side of the connecting plate.

[0014] Furthermore: the hinge arm is provided with a transverse mounting groove, the connecting plate extends into the transverse mounting groove, the transverse guide groove is located on the side wall of the transverse mounting groove, and the transverse guide block is installed into the transverse guide groove from the end face of the transverse guide groove.

[0015] Furthermore, the lateral adjustment device is a lateral adjustment eccentric pin riveted to the transfer plate. Correspondingly, a lateral adjustment drive groove is provided inside the hinge arm, and the lateral adjustment eccentric pin rotates within the lateral adjustment drive groove.

[0016] Furthermore: the vertical guide groove is a hook formed by pressing and bending the base plate material upwards, and at least two pairs of hooks are provided, which are distributed in a left-right relative interval, and the transfer plate is installed in the hook.

[0027] The present invention will be further described in detail below with reference to the accompanying drawings. A multi-dimensional adjustable hardware hinge includes a hinge arm 1, on which an upper connecting rod 2 and a lower connecting rod 3 are hingedly mounted;

[0028] The other ends of the upper connecting rod 2 and the lower connecting rod 3 are hinged to the hinge cup 4. The upper connecting rod 2 and the lower connecting rod 3 rotate relative to the hinge arm 1 and the hinge cup 4 to realize the opening and closing of the hinge.

[0029] The hinge arm 1 covers the transfer plate 5. A transverse guide groove 11 is provided at the bottom of the hinge arm 1. A transverse guide block 51 is provided on the transfer plate 5. The transverse guide block 51 is slidably installed in the transverse guide groove 11 to realize the connection between the hinge arm 1 and the transfer plate 5. A transverse adjustment device is provided between the hinge arm 1 and the transfer plate 5 to drive the relative transverse displacement of the two.

[0030] It also includes a base plate 6, on which a vertical guide groove 61 is provided, and a vertical guide block 52 is provided on the transfer plate 5. The vertical guide block 52 is slidably installed in the vertical guide groove 61 to realize the connection between the base plate 6 and the transfer plate 5. A vertical adjustment device is provided between the base plate 6 and the transfer plate 5 to drive the relative vertical displacement between the two.

[0031] In one embodiment: the transfer plate 5 has connecting plates 53 bent upwards on both the upper and lower sides, and the lateral guide block 51 is disposed on the outer side of the connecting plate 53.

[0032] In one embodiment: a transverse mounting groove 12 is provided in the hinge arm 1, the connecting plate 53 extends into the transverse mounting groove 12, the transverse guide groove 11 is located on the side wall of the transverse mounting groove 12, and the transverse guide block 51 is installed into the transverse guide groove 11 from the end face of the transverse guide groove 11.

[0033] In one embodiment: the lateral adjustment device is a lateral adjustment eccentric nail 54 riveted to the transfer plate 5. Correspondingly, a lateral adjustment drive groove 13 is provided in the hinge arm 1, and the lateral adjustment eccentric nail 54 rotates within the lateral adjustment drive groove 13.

[0034] In one embodiment: the vertical guide groove 61 is a hook 62 formed by pressing and bending the base plate 6 body material upwards. At least two pairs of hooks 62 are provided, which are distributed in a left-right relative interval. The transfer plate 5 is installed in the hook 62.

[0035] In one embodiment: the vertical adjustment device is a vertical adjustment eccentric nail 63 riveted to the base plate 6. Correspondingly, a vertical adjustment drive groove 55 is provided in the transfer plate 5, and the vertical adjustment eccentric nail 63 rotates within the vertical adjustment drive groove 55.

[0036] In one embodiment: the base plate 6 is provided with a plurality of mounting holes 65, and correspondingly, the hinge arm 1 is provided with a clearance groove 14 at the position corresponding to the mounting holes 65, and the fixing screw passes through the clearance groove 14 and the mounting holes 65 to connect with the fixing object.

[0037] In one embodiment, an adjustment groove 15 is provided on the hinge arm 1 at the position corresponding to the vertical adjustment eccentric nail 63.

[0038] Working principle: This utility model provides a multi-dimensional adjustable hardware hinge. Through the coordinated design of the hinge arm, the transfer plate and the base plate, as well as the combination of the horizontal adjustment device and the vertical adjustment device, it realizes the precise adjustment of the hinge in both horizontal and vertical directions, and meets the needs of multi-dimensional position adjustment.

[0039] Specifically: A transverse guide groove 11 is provided at the bottom of the hinge arm 1, and a transverse guide block 51 on the transfer plate 5 is slidably installed in the transverse guide groove 11. The sliding of the transverse guide block 51 in the transverse guide groove 11 can realize the transverse displacement adjustment of the hinge arm 1 relative to the transfer plate 5.

[0040] During lateral adjustment: The lateral adjustment device consists of a lateral adjustment eccentric pin 54 riveted to the central plate 5. When the user rotates the eccentric pin 54, due to the asymmetrical structure of the eccentric pin, a relative lateral displacement is generated between the hinge arm 1 and the central plate 5. The position of the eccentric pin is confined within the lateral adjustment drive groove 13 inside the hinge arm, thereby ensuring a smooth and precise adjustment process.

[0041] By combining a sliding connection with an eccentric pin adjustment, the lateral adjustment device not only achieves high-precision lateral position adjustment but also simplifies the structural design and reduces adjustment errors and frictional losses. During adjustment, users can easily complete the lateral adjustment simply by adjusting the eccentric pin, eliminating the need for complex operations and significantly improving adjustment efficiency and user experience.

[0042] During vertical adjustment: A vertical guide groove 61 is provided on the base plate 6, and a vertical guide block 52 is provided on the transfer plate 5. The vertical guide block 52 is slidably installed in the vertical guide groove 61, so that the base plate 6 and the transfer plate 5 can move relative to each other in the vertical direction.

[0043] The vertical adjustment device consists of a vertical adjustment eccentric pin 63 riveted to the base plate 6. The eccentric pin is located in the vertical adjustment drive groove 55 within the transfer plate 5. When the user rotates the eccentric pin, its eccentric design drives vertical displacement between the base plate 6 and the transfer plate 5, thereby achieving vertical adjustment.

[0044] The vertical adjustment device also employs a structural design combining eccentric nails and guide grooves, ensuring the stability and precision of the adjustment process. The sliding connection between the transfer plate and the base plate makes the adjustment process smoother, avoiding the loosening and instability problems caused by the complex structure in traditional adjustment methods.

[0045] In this case, the intermediate connecting plate 5, serving as the intermediate connecting component between the hinge arm 1 and the base plate 6, enables independent adjustment of the hinge in two directions through the cooperation of the lateral and vertical adjustment devices. The lateral and vertical adjustments do not interfere with each other, allowing users to make precise adjustments according to actual installation needs.

[0046] The transfer plate 5 is also designed with connecting plates 53 on both sides, which, in combination with the lateral mounting groove 12 and lateral guide groove 11 of the hinge arm 1, further improve the stability of the structure.

[0047] The modular design enhances the hinge's versatility, making it suitable for various installation scenarios and door panels of different sizes. Furthermore, the intermediate connecting plate effectively distributes the mechanical load, improving the overall load-bearing capacity and durability of the hinge.

[0048] It should be noted that several mounting holes 65 are provided on the base plate 6 for securing the hinge as a whole. To avoid interference between the fixing screws and the adjustment device, clearance grooves 14 are provided on the hinge arm 1 corresponding to the positions of the mounting holes 65, ensuring smooth screw installation. Furthermore, an adjustment groove 15 is provided on the hinge arm 1 at the position of the vertical adjustment eccentric pin 63, allowing the user to easily access and adjust the eccentric pin, simplifying the adjustment operation. The design of the clearance groove and adjustment groove optimizes the hinge installation and adjustment process, further enhancing the user experience. At the same time, the reasonable structural design avoids interference problems during installation, ensuring a smooth and unobstructed installation process.

[0049] In practical use, users can first fix the hinge in the installation position using the base plate 6, and then use the vertical adjustment device to adjust the relative position between the transfer plate 5 and the base plate 6 to ensure that the vertical position of the hinge is accurate.

[0050] Subsequently, the lateral position between hinge arm 1 and the central plate 5 is adjusted using a lateral adjustment device to ensure that the position and clearance of the door panel meet the requirements. After the door panel is installed, the hinge can smoothly open and close via the linkage structure.

[0051] Compared with traditional technologies, the multi-dimensional adjustment function in this case enables independent adjustment in both horizontal and vertical directions, adapting to various installation needs and improving installation accuracy, thus making it widely applicable.

[0052] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
