Description
Technical field
The utility model relates to a kind of structure-improved that presss from both sides the formula rotating shaft of pulling that suppresses.
Background technique
Along with various electronic products with flip or screen constantly by exploitation and come into the market; The pivot of its widespread usage is turned round the also continuous modified renewal of device; Like Fig. 1, shown in 2; System is that a common pivot is turned round device, and its structure comprises: first and second cam 6 that pin joint seat 5, axle 50, two are identical, 6a, two identical fixed plate 7,7a and elastic elements 70 etc.; Wherein pin joint seat 5 has a vertically extending side plate 51; Be provided with a pivot hole 52 in these side plate 51 central authorities; And be provided with a protruding stopper part 55 at these pivot hole 52 sides, axle 50 stage casings are provided with a lip part 501, and are provided with the restriction shaft part 502 on a tool plane 503 at axle 50 1 ends; This restriction shaft part 502 can pass the pivot hole 52 of side plate 51; And with lip part 501 blocks in side plate 51, between this lip part 501 and side plate 51, can be provided with one with the stop block 56 of axle 50 pivot in unison, be provided with two relative blocked parts 561 in these stop block 56 all sides; But these two blocked parts, 561 blocks are in the stopper part 55 of side plate 51 and form the restriction of a pivoting angle; First and second cam 6,6a are sleeved on this restriction shaft part 502 pivotly, and this first cam 6 is with fixing part (as: two fixed holes 53, or two fixed grooves 54 of two fixing pins, 61 build-ins, two correspondences on side plate 51; Or a fixed hole 53 and a fixed groove 54), the second cam 6a is with two fixing pin 61a build-ins, two corresponding fixing parts (as: two fixed grooves 71) on this fixed plate 7; Opposite side at this first and second cam 6,6a has a rubbing surface respectively, on this rubbing surface, is respectively equipped with protuberance 64,64a and recess 63,63a; Fixed plate 7,7a can be arranged on this restriction shaft part 502 synchronously linkedly; Between fixed plate 7,7a, be provided with an elastic element 70; This elastic element 70 can be made up of the plural number and 701 of the arc spring laminations of restriction shaft part 502 synchronous interlocks, is provided with a packing element 504 at the end that limits shaft part 502 in addition and pushes against in this fixed plate 7a.
Said structure is when practical application; When this first and second cam 6, when 6a is in initial position; Protuberance 64 correspondences of first cam 6 are embedded in the recess 63a of the second cam 6a, and the protuberance 64a correspondence of the second cam 6a is embedded in the recess 63 of first cam 6, use to form the location;
And when axle 50 is rotated with respect to this pin joint seat 5; Its restriction shaft part 502 drives fixed plate 7 and rotates, and makes the second cam 6a rotate synchronously with axle 50, and then the protuberance 64 of first cam 6 shifts out the recess 63 of the second cam 6a; The protuberance 64 of this cam 6 of winning contacts with the rubbing surface of the second cam 6a; The protuberance 64a of the second cam 6a shifts out the recess 63 of first cam 6 simultaneously, makes the protuberance 64a of the second cam 6a contact with the rubbing surface of first cam 6, and produces the variation of torsion; When pin joint seat 5 and axle 50 resetted, protuberance 64,64a can move closer to recess 63a, 63, and corresponding once more and automatic chimeric answer.
Yet, though this kind structure can provide this axle 50 in the location of special angle, the frictional force required with general fixed angle; But it is comparatively limited by 701 elasticity that can produce of plural arc spring lamination; And be difficult to produce bigger frictional force, thereby can't satisfy the required big frictional force in more large-scale electronic product pivot location, simultaneously; This kind forms structure and assembling mode is comparatively complicated; Be difficult for to change this elastic element 70, so it also is can't adjust for fixing for 50 frictional force that can produce of axle basically, this all possibly cause the disappearance in the application.
