1. a stiffness-adjustable mutative damp back vibration isolator, including housing (10) and central shaft (11), described central shaft (11)Being vertically arranged in housing (10), it is characterized in that, the two ends up and down of described housing (10) form horizontal vibration damping chamber, institute respectivelyThe two ends up and down stating central shaft (11) lay respectively at two horizontal vibration damping intracavity, and described two horizontal vibration damping intracavity are separately provided forRegulation central shaft (11) moves horizontally the adjusting means of rigidity and damping;

  • Described adjusting means includes antivibrator, inner cone spring(7) and interior Adjusting bolt Adjusting screw (2), described interior Adjusting bolt Adjusting screw (2) spiral is connected to the termination of central shaft (11), describedAntivibrator include damping baffle ring (6) and damping conical ring (8), described damping baffle ring (6), damp conical ring (8) and inner coneSpring (7) from inside to outside be arranged on horizontal vibration damping intracavity, and be socketed on central shaft (11), described damping baffle ring (6)And between damping conical ring (8), form cone match;

    The external diameter of described damping baffle ring (6) is suitable with the internal diameter in horizontal vibration damping chamber,The first mobile space is there is between inner hole wall and the central shaft (11) of described damping baffle ring (6);

    Described damping conical ring (8)Endoporus is adaptive with the diameter of central shaft (11), has second between outer wall and the inwall of shock-isolation chamber of described damping conical ring (8)Mobile space;

    One end of described inner cone spring (7) offsets with interior Adjusting bolt Adjusting screw (2), another of described inner cone spring (7)End offsets with antivibrator.
