Example Embodiment
[0025] figure 1 A partial top view of the tripod head of the present invention is shown. figure 2 with image 3 Shown in the figure is a base 10 (second body). A shaft 20 (first body) is rotatably installed in the base 10 through a bearing 11 and connected to the intermediate body of the tripod head not shown in the figure. The shaft 20 can rotate about the pivot 21 relative to the base 10, and the base 10 is usually fixed on a tripod. The base body 10 in the illustrated embodiment includes two half-shells 12a, 12b.
[0026] In order to dampen the rotational movement of the shaft 20 relative to the base body 10, a damping device 30 is provided. The damping device mainly includes a first damping element 31 and a second damping element 32.
[0027] The first damping element 31 has an annular chassis 33 coaxial with the pivot 21. A number of concentrically arranged annular ribs 34 extend from the chassis 33 along the axis (in the direction of the pivot 21). A cavity 35 is formed b...
