一种阻尼可调的球壳

Abstract

本申请涉及一种阻尼可调的球壳，涉及转动连接件技术领域，包括上壳体、下壳体，所述上壳体和下壳体间设有调节体，球面分别位于上壳体和调节体上，所述调节体的底部固定有螺纹段，所述螺纹段与下壳体螺纹连接，所述调节体的一侧固定连接有手柄，所述下壳体设有供手柄穿过的调节槽。所述手柄为L形，所述手柄贴合于上壳体的外表面设置。所述上壳体内固定有密封筒，所述密封筒套设于调节体的侧壁顶部且与调节体的侧壁呈环形接触。本申请能够便捷地调节对球头的夹紧力度，对球头的转动阻尼进行调节；当球头磨损导致间隙扩大，球头转动的阻尼感变弱后，通过转动手柄使调节体靠近上壳体，恢复球头的转动阻尼。
