Description

Technical Field

[0001] This utility model belongs to the field of hinge technology, specifically relating to a three-dimensional adjustable hinge. Background Technology

[0002] Hinges, as the core basic component that enables rotational connection between two parts, are widely used in furniture manufacturing, building door and window systems, electronic equipment, transportation vehicles and many other fields. Their performance directly affects the smoothness of opening and closing, structural stability and service life of the product.

[0003] In actual production and installation, due to processing errors, cumulative assembly errors, and personalized requirements of application scenarios (such as non-standard sizes of customized furniture and deviations in wall verticality during the installation of building doors and windows), the adjustment function of hinges has been put forward as a key requirement. That is, by adjusting the position of the hinge, the above errors can be compensated to ensure that the two connecting parts can be precisely aligned, so as to avoid problems such as jamming when opening and closing, poor sealing, uneven gaps, or local stress concentration.

[0004] While existing hinges are adjustable, most only support single-dimensional adjustment. Some high-end products offer two-dimensional adjustment, but these cannot meet the need for adjustment along the depth of the component. For example, in cabinet door installation, if there is a misalignment between the door and the cabinet body in the front-to-back direction, existing two-dimensional adjustable hinges cannot compensate for this deviation. This results in the door not being flush with the side of the cabinet body when closed, affecting both appearance and usability. Consequently, the installation requirements for these hinges are high, and the installation is difficult. Utility Model Content
