[0002] In the field of cabinet furniture and building decoration, as the core component connecting cabinet door and cabinet body, the functionality of hinge directly affects user experience and product life. Although the traditional hinge can meet the basic opening and closing requirements, there are still the following technical bottlenecks in practical application:
[0003] I. The deficiency of adjustment degree and flexibility: most existing hinges adopt single direction adjustment structure (such as height or gap fine adjustment).
[0004] II. The inherent defect of limited opening and closing angle: the traditional hinge is limited by the design of rotating shaft structure, and the maximum opening and closing angle is usually less than 170°, resulting in large space occupation and blocked view when opening the cabinet door. Although some hinges can realize 180° opening and closing, the complex multi-stage linkage mechanism significantly increases the manufacturing cost, and the opening and closing trajectory is easy to deviate due to the wear of connecting rod after long-term use.
