Description

Technical Field

[0001] The utility model relates to the technical field of hinges, in particular to a hidden damping hinge with magnetic force. Background Art

[0002] Traditional hinges usually rely on the tension of springs to close cabinet doors. However, there are some inherent problems with this design. First, springs are prone to fatigue after long-term use, resulting in a weakened closing force, which makes it impossible to effectively close the cabinet door, causing inconvenience to users. Secondly, traditional hinges often lack fine adjustment functions, especially in three-dimensional directions, which makes it difficult to achieve perfect alignment and stable operation of cabinet doors during installation. Finally, traditional hinges often lack anti-walking functions and have limited ability to prevent cabinet doors from sagging or moving left and right under the action of gravity, which may cause the gap between the cabinet door and the door frame to change, affecting the appearance and function. Therefore, there is an urgent need for a hidden damping hinge with magnetic force. Utility Model Content
