    • A vibration damping mechanism for utility poles includes a cylindrical hollow tube including a sidewall having outer and inner side surfaces. The inner side surface forms an elongated inner chamber defining a longitudinal axis and having longitudinally spaced upper and lower ends. An unrestricted cylindrical rod disposed in the chamber is capable of limited movement in the chamber to damp oscillations. A section of the tube's sidewall is flat to form vertical flats along the outer and inner side surfaces. Formed portions of the sidewall disposed at respective upper and lower ends of the chamber are bent inwardly to extend across, and close, the upper and lower chamber ends, respectively. The lower one of the formed portions is shaped to define a raised pivot engaging a bottom face of the rod at a location laterally inwardly of the rod's outer side face.
    • 用于电杆的减振机构包括:圆筒形中空管,其包括具有外侧面和内侧面的侧壁。 内侧表面形成限定纵向轴线并具有纵向间隔开的上端和下端的细长内腔。 设置在腔室中的不受限制的圆柱形杆能够限制腔室中的运动以阻止振荡。 管的侧壁的一部分是平的,以沿着外表面和内侧表面形成垂直平面。 设置在腔室的相应上端和下端处的侧壁的形成部分向内弯曲以分别延伸并关闭上部和下部腔室端部。 下形成的部分被成形为限定在杆的外侧面的横向内侧的位置处接合杆的底面的凸起枢轴。
