Embodiment

The technological scheme that the utility model provides is: the upper and lower surface at the rotating base supporting disk the brim of a hat all is provided with annular groove, ball and locking plate are set in groove, the top bottom-disc of rotating base be provided with supporting disk the brim of a hat upper surface on the corresponding annular groove of annular groove, the low bottom-disc of rotating base be provided with supporting disk the brim of a hat lower surface on the corresponding annular groove of annular groove, supporting disk rolls between top bottom-disc and low bottom-disc by the rolling of two-layer ball up and down.

In order to make the purpose of this utility model, technological scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.

As Fig. 1, Fig. 2 and shown in Figure 3, the rotating base that the utility model embodiment provides comprises support 1, bottom 2, top bottom-disc 3, supporting disk 4, ball 5, locking plate 6, low bottom-disc 7 and the base plate 8 that links to each other with flat panel TV.Wherein:

Support 1 is a T shape plate, is used to connect television set and supporting disk 4.On the vertical plane of T shape timbering 1 screw hole is arranged, be used for support 1 is fixed in television set; Also be provided with screw hole 11 on T shape timbering 1 horizontal plane, this screw hole 11 is corresponding with the screw hole 41 of supporting disk 4 upsides.

Bottom 2 is a discoid plastic parts, and middle perforation has two apertures 21 in addition, and screw passes aperture 21 bottom 2 is fixed on the top bottom-disc 3.

Top bottom-disc 3 is a circular steel plate, and several screw holes 31 are arranged on it, can be screwed top bottom-disc 3 by screw hole 31, and a ring groove 32 is arranged under it, and ball 5 can roll in this groove 32.
