Please refer to Fig. 1, the better embodiment of pivot device of the present invention comprises that one first link 10, one second link 20, an axostylus axostyle 30, a sleeve 40, some friction plates 50, roughly are the snap ring 60 of " C " shape, shell fragment group 80, a pad 85 and the fixed block 90 that an elastic component 70, comprises several resilient pads.In the present embodiment, elastic component 70 is a spring.First link 10 and second link 20 are respectively applied for and are fixed on two parts that need to rotate mutually, as the loam cake and the base of electronic equipment.

First link 10 comprises a fixed plate 12.Fixed plate 12 is provided with plurality of fixed hole 120, passes for screw or rivet, thereby the base of first link 10 with electronic equipment fixed.One side of fixed plate 12 has extended to form the through hole 160 that one first connecting plate, 16, the first connecting plates 16 offer a flat vertically upward.The opposite side relative with first connecting plate 16 of fixed plate 12 extended to form the through hole 180 that through hole 160 that 18 pairs of one second connecting plate, 18, the second connecting plates should first connecting plate 16 offers a flat vertically upward.Fixed plate 12 forms an interference plate 122 in these second connecting plate, 18 1 side direction away from the direction horizontal-extending of this first connecting plate 16, and the end of this interference plate 122 extends to form an interference part 14 obliquely, and interference part 14 protrudes out a clamping block 142 to a side.

Second link 20 comprises that a junction 22 and is from a locking part 21 that a side vertical extent of joint 22 forms.The front end of locking part 21 is provided with the through hole 212 of a circle, and locking part 21 is offered in the bilateral symmetry of this through hole 212 and is roughly one first square bayonet socket 210 and one second bayonet socket 213.Joint 22 is provided with plurality of fixed hole 220, passes for screw or rivet, thereby the loam cake of first link 20 with electronic equipment fixed.

Axostylus axostyle 30 comprises the less fixing part 34 of diameter that a cross section is the body of rod of flat (not label) and extends to form from an end of this body of rod.End peripheral indentation moulding one draw-in groove 32 away from this fixing part 34 of axostylus axostyle 30.Fixing part 34 has flat sectional shape and is provided with screw thread at its end, so that be screwed with fixed block 90.

Sleeve 40 is the cylindrical shell of hollow, depression moulding one spiral helicine chute 42 on its periphery.Two fixture blocks 44 of extension vertically of one end symmetry of sleeve 40.The sectional shape of two fixture blocks 44 is corresponding with first and second bayonet socket 210,213 of second link 20 respectively.

Each friction plate 50 is provided with one can be sheathed and be fixed in the fixed hole 52 of the fixing part 34 of axostylus axostyle 30.

Each shell fragment of this shell fragment group 80 all offers the through hole 82 of the fixing part 34 of corresponding sheathed axostylus axostyle 30.

Pad 85 is provided with one can be sheathed and be fixed in the flat hole 86 of the fixing part 34 of axostylus axostyle 30.

This fixed block 90 is a nut in the present embodiment, its can be sheathed and screw lock on the screw thread of the fixing part 34 of axostylus axostyle 30.

Please join in conjunction with shining Fig. 2 and Fig. 3, during assembling, axostylus axostyle 30 passes another through hole 160 of a through hole 180, elastic component 70 and first link 10 of first link 10 successively away from an end of fixing part 34, and snap ring 60 is sticked in the draw-in groove 32 of axostylus axostyle 30, and is resisted against first connecting plate 16 of first link 10.Two opposite ends of elastic component 70 are resisted against second connecting plate 18 and the snap ring 60 of first link 10 respectively.The end that axostylus axostyle 30 is provided with fixing part 34 passes sleeve 40, wherein fixed hole 52, the through hole 212 of second link 20, the fixed hole 52 of another part friction plate 50, the through hole 82 of shell fragment group 80 and the flat hole 86 of pad 85 of a part of friction plate 50 successively, then with fixed block 90 screw locks in the screw thread of fixing part 34.Described fixed block 90 is used to prevent the terminal landing from fixing part 34 of pad 85, shell fragment group 80, friction plate 50 and second link 20.

In above-mentioned assembling, fixing part 34 passes the through hole 212 of second link 20 rotationally, thereby second link 20 can rotate with respect to axostylus axostyle 30.Two fixture blocks 44 of sleeve 40 are sticked in first and second bayonet socket 210,213 of second link 20 respectively, thereby the sleeve 40 and second link 20 are interfixed, and with second link, 20 interlocks.The clamping block 142 of first link 10 slidably is sticked in the chute 42 of sleeve 40.

Please refer to Fig. 4, during use, the loam cake of rotating electric device rotates with respect to axostylus axostyle 30 together thereby drive second link 20 and sleeve 40.The clamping block 142 of first link 10 is along chute 42 slips and promote sleeve 40 away from first link 10, thereby promote all first link, 10 motions dorsad of second link 20 and axostylus axostyle 30, laterally move with respect to the direction of base while opening along axostylus axostyle 30 with the loam cake of realizing electronic equipment.In said process, snap ring 60 along with axostylus axostyle 30 motion away from first connecting plate 16, thereby compression elastic piece 70.Therefore, the reaction force that provides of the axial deformation of elasticity group 80 and elastic component 70 can make the loam cake of electronic equipment move axially steadily.

When counterrotating second link 20, the clamping block 142 of first link 10 is along chute 42 slips and force sleeve 40 close to first link 10, thereby drive second link 20 and axostylus axostyle 30 all towards 10 motions of first link, and the active force that elastic component 70 recovers the distortion generation also promotes snap ring 60 simultaneously and drives first connecting plate 16 motions of axostylus axostyle 30 to first link 10.Thereby the loam cake of realizing electronic equipment resets and covers with respect to base.

In addition, between described shell fragment group 80 and friction plate 50, also concavo-convex the wheel can be set, to realize functions such as easy opening and heavy closing, auto-closing.
