Embodiment

For further understanding feature of the present utility model, technological means and the concrete function of being reached, purpose, enumerate than specific embodiment now, and be described with reference to the accompanying drawings as after.

See also Fig. 1 to shown in Figure 3, in preferred embodiment, pivot device comprises: formations such as first wrapping plate 10, second wrapping plate 20 and axle 30; First wrapping plate 10 has opening 11, the second wrapping plates 20 and has opening 21 and straight part 22; First shaft part 31 of axle 30 is hubbed at first wrapping plate 10, and second shaft part 32 of axle 30 is hubbed at second wrapping plate 20; Wherein, second shaft part 32 has straight part 33, and when the straight part 33 of second shaft part 32 fitted in the straight part 22 of second wrapping plate 20, pivot device was blocking, first wrapping plate 10 and second wrapping plate 20 also are shaped in fixed plate 40, and fixed plate 40 is provided with a plurality of positioning holes 41; By this, first wrapping plate 10 and first shaft part 31 can reach the effect of easy opening and heavy closing, and second wrapping plate 20 and second shaft part 32 can reach the effect that has easy opening and heavy closing concurrently and fall automatically.

As Fig. 2, shown in Figure 3, first wrapping plate 10 can have identical length or have length inequality with second wrapping plate 20, with the effect of adjusting easy opening and heavy closing and falling automatically.Moreover, be provided with groove 34 between first shaft part 31 and second shaft part 32, form gap 13 between first wrapping plate 10 and second wrapping plate 20, and the position of groove 34 is corresponding to gap 13, make axle 30 in the process of rotation, second shaft part 32 does not contact with first wrapping plate 10, and first shaft part 31 do not contact with second wrapping plate 20, to prevent mutual interference.In addition, the end of first shaft part 31 is provided with lip part 35, is deviate from by the end of first shaft part 31 to prevent first wrapping plate 10, can further be provided with groove 36 between the lip part 35 and first shaft part 31.

See also Fig. 5 to shown in Figure 7, if pivot device is implemented on cover-lifting type electronic device (figure does not show), when axle 30 turns clockwise, effect because of frictional force, first shaft part 31 will strut first wrapping plate 10, and second shaft part 32 will strut second wrapping plate 20, and form lower friction torsion, make the lid of cover-lifting type electronic device be easy to open; When axle 30 is rotated counterclockwise, because of the effect of frictional force, first wrapping plate 10 will be closed more, and second wrapping plate 20 will be closed more, and form higher friction torsion, make the lid of cover-lifting type electronic device can obtain suitable support force, and reach the effect of easy opening and heavy closing.Moreover, in the process that axle 30 is rotated counterclockwise, the straight part 33 of second shaft part 32 will level off to the straight part 22 of second wrapping plate 20 gradually, and under the effect of second wrapping plate 20, the straight part 33 of second shaft part 32 will fit in the straight part 22 of second wrapping plate 20, and reach the effect that falls automatically.

Pivot device of the present utility model can reduce the abrasion of axle 30, and then increases the life-span of pivot device, gives being described as follows now:

The utility model with first shaft part 31 and first wrapping plate 10 as supporting and the main active region of friction, and with second shaft part 32 and second wrapping plate 20 as the main active region that falls automatically, because, first shaft part 31 and first wrapping plate 10 do not have straight part, so the abrasion situation of first shaft part 31 in first wrapping plate 10 is lower than the abrasion situation of second shaft part 32 in second wrapping plate 20.Otherwise, if axle 30 only has single shaft part, and this single shaft part and first and

second wrapping plate

10,20 all have straight part, then this single shaft part and first and

second wrapping plate

10,20 whole section zone all becomes the active region of supporting and rubbing, simultaneously, whole section zone of this single shaft part and first and

second wrapping plate

10,20 also becomes the active region that falls automatically, so the abrasion situation of the straight part of this single shaft part is comparatively serious.

See also Fig. 8 to shown in Figure 9, in a second embodiment, the first wrapping plate 10a and the second wrapping plate 20a are stand-alone assemblies, and the extension part 15 of the first wrapping plate 10a is provided with the extension part 25 of a plurality of positioning hole 16, the second wrapping plate 20a and is provided with a plurality of positioning holes 26; Wherein, form gap 13 between the first wrapping plate 10a and the second wrapping plate 20a, make the groove 34 of axle 30 corresponding to gap 13.
