Detailed ways

The utility model will be described in further detail below in conjunction with the accompanying drawings:

Please refer to shown in Fig. 1, the mobile product supporting device of the preferred embodiment of the present utility model is used for supporting a mobile product 10 (referring to Fig. 6), and this mobile product 10 is generally the playback equipment of audio/video multimedia, as VCD/DVD playback device etc. The support device is installed on the casing 12 of the mobile product, and the support device includes a fixed seat 20 fixed on the casing 12, a support frame 30, a washer 40, a spring 50 and a screw 60 with a washer . Wherein, the gasket 40 is made of metal material.

Please continue to refer to FIG. 2 , the fixing base 20 is installed on the housing 12 of the mobile product 10 through screws or other fasteners, or the fixing base 20 is integrally formed with the housing 12 . The fixing base 20 has a connecting block 22 and a bearing 24 extending upward from the connecting block 22 . The bearing 24 defines a through shaft hole 241 transversely, and the inner wall of the shaft hole defines an arc-shaped groove 242 along the axial direction of the shaft hole. In this embodiment, the arc of the arc groove 242 is 90 degrees. One end of the bearing 24 is provided with a plurality of spaced protrusions 243 distributed in a tooth shape, and the protrusions 243 have inclined engagement surfaces 245 .

Please continue to refer to FIG. 3 , the support frame 30 is provided with a support bar 32 and a rotating shaft 34 vertically extending from one end of the support bar 32 . One end of the supporting bar 32 defines a circular recess 321 , and the rotating shaft 34 vertically extends outward from the middle of the recess 321 . A plurality of spaced protrusions 323 protrude from the inner wall of the recess 321 , and the protrusions 323 engage with the protrusions 243 . One end of the rotating shaft 34 is formed with a first shaft portion 35 with a larger diameter, and the other end of the rotating shaft 34 is provided with a second shaft portion 36 with a smaller diameter. The outer surface of the second shaft portion 36 is along the second axis. A stopper 362 protrudes axially from the second shaft portion 36 , and a screw hole 364 cooperating with the screw 60 is defined in the axial direction at one end of the second shaft portion 36 .
