Abstract
This utility model discloses a novel hydraulic damper. Key technical features include a housing with an oil cavity inside. A rotating shaft is rotatably connected to the housing, extending into the oil cavity and symmetrically arranged with blades. Each blade has a notch. A flexible paddle covering the notch is positioned on one side of the blade. A limiting element is positioned on the side of the flexible paddle away from the notch. When the flexible paddle deforms away from the notch, an oil passage gap is formed between it and the notch, and it abuts against the limiting element. This utility model achieves dynamic adjustment of the damping force by allowing the flexible paddle to deform with changes in hydraulic oil pressure, adapting to different speeds and loads. Furthermore, by setting a limiting element to restrict its maximum bending angle, it avoids plastic damage or breakage due to excessive deformation, significantly extending the service life of the damper.
