A type of furniture cabinet using a two-stage force-reducing hinge
This utility model relates to the field of hinge technology, specifically to a two-stage force-buffered hinge for furniture cabinets. This hinge achieves two-stage motion control through the synergistic action of a torsion spring and a damping cylinder. When the cabinet door is opened, the torsion spring accumulates energy while the damping cylinder provides initial buffer resistance. When a specific angle is reached, the damping cylinder automatically switches to progressive strong damping. During the closing process, the torsion spring releases energy to assist in resetting. The damping system offsets the impact force in stages, enabling the cabinet door to achieve stepless hovering at any position, avoiding the sudden opening and closing phenomenon of traditional hinges, significantly reducing cabinet collision noise. The rigid connection between the fixed side plate and the hinge seat ensures the overall load-bearing strength. The rubber gasket continuously absorbs vibration energy to prevent screws from loosening. The linkage structure between the main hinge arm and the inner rocker arm maintains precise motion trajectory. The sliding cooperation between the connecting block and the moving block eliminates mechanical clearance. The fixed shaft maintains the axial stability of the damping assembly.
