Description
Technical field
The utility model is relevant a kind of rotating shaft, refers to a kind of cladding type rotary shaft structure of anti-disengagement especially, and it can avoid the axial disengagement of the coating member and the pivot of turning shaft structure.
Background technique
Press the consumption electronic products of tool flip, such as portable computer, e-dictionary, portable video-audio playing device and cover-lifting type mobile phone ... Deng, basically, be that main body is placed Lower Half, and be connected the folding that lid be can be with respect to body by the lid of the rotating shaft and the first half.Therefore, rotating shaft is also for determining a big essential factor of the said goods quality.
It promptly is example with the cladding type rotary shaft, it is to be sheathed on a coating member by a jack-post, and this a coating member radially end radially extends a junction, so that be connected with the lid of electronic product, and form an opening that lies across between this coating member and joint, make this rotating shaft have " easy opening and heavy closing " function.No doubt this jack-post outer end intercalation one retaining tenon, so as with the arc blocked part of coating member end projection, form the restriction of folding angle.Simultaneously, prop up the coating member end, with as the anti-function of throwing off by this retaining tenon.Only this rotating shaft can be carried out the folding life test usually before dispatching from the factory, and in this test phase, the retaining tenon is not intercalated in jack-post as yet, and therefore, if having a bigger tolerance between coating member and jack-post, so that both still have possibility of disengagement, and demand improvement urgently.
In view of this, shown in " rotating shaft prevent deviating from structure " of the TaiWan, China patent announcement that is had as this creation claimant M315479 number, it is made up of a sleeve member and an axis bar.This sleeve member lower hollow cylindrical shell is separated at least two bunching rings via at least one profile groove, and each bunching ring one end radially extends a sheet, and end then forms an opening with the frame sheet in addition; And axis bar one end has a convergence part, and end then extends axially a jack-post in addition, dashes forward corresponding to the profile groove position and establish at least one bulge loop in this jack-post surface, and its both sides are respectively in abutting connection with a friction section; So that after jack-post and each bunching ring socket, each friction section lays respectively in the corresponding bunching ring, and bulge loop is placed in the profile groove, prevents deviating from structure with what rotating shaft was provided.No doubt this case can be obtained desired rotating shaft and prevents deviating from function, only the coating member structure of socket (coating) formula rotating shaft is identical not to the utmost completely, for example can't offer the buckle of profile groove for bulge loop, so for different structure, then need look for another way, this is the problem that the dealer must face jointly.

Description of drawings
Be further to disclose concrete technology contents of the present utility model, below in conjunction with embodiment and accompanying drawing describes in detail as after, wherein:
Fig. 1 is the three-dimensional exploded view of the utility model cladding type rotary shaft structure;
Fig. 2 is the stereogram of the utility model group after upright;
The sectional drawing that Fig. 3 is intercepted along line A-A for Fig. 2.
Embodiment
As shown in Figure 1 to Figure 3, basically, cladding type rotary shaft structure of the present utility model is by a coating member 1, one pivot 2, and positioning piece 3 combines.
Coating member 1 is a support body, and it axially has a hollow and coats end 11, and a side of this coating member 1 is prominent establishes a tenon 12, in order to the intercalation and the location of this locating piece 3.Moreover, the prominent blocked part 13 of establishing of another side of this coating member 1, the usefulness of angle limits with as these pivot 2 rotations the time.And be to make this coating member 1 be connected in the lid of electronic product, therefore, this coating end 11 extends radially out a junction 14, for example through the lamellar body of bending, this joint 14 is offered a plurality of conjugate foramens 141, so that utilize known coupling unit, after for example screw or rivet pass through, combine with lid in direct or indirect mode, make this coating member 1 can be along with lid rotates.
And the creative feature of this coating member 1 is, these coating end 11 inside are provided with a ring groove 111, so that be interlockingly connected for the bulge loop 231 of pivot 2, thereby obtains anti-purpose of throwing off.
This convergence part 21 sides in addition is provided with an axle collar 22, its be when coating end 11 sockets with one as the usefulness of contact, and this axle collar 22 extends axially an axostylus axostyle 23, only this is a known technology all, does not intend giving unnecessary details at this.And the characteristics of this axostylus axostyle 23 are, it establishes the bulge loop 231 of at least one external diameter maximum corresponding to ring groove 111 positions are prominent, and these axostylus axostyle 23 surfaces must form a curvilinear oil duct 232, and ccontaining for lubricant oil is to provide lubricated effect.In addition, these axostylus axostyle 23 front-end edges are radially offered a mortise 233, and it is the intercalation for a retaining tenon 24, make this retaining tenon 24 hold the restriction of the blocked part 13 of 11 outside projections as the folding angle with this coating.
As shown in Figures 2 and 3, the utility model in actual sets immediately, at first the axostylus axostyle 23 with this pivot 2 is sheathed in the coating end 11 of coating member 1, make the bulge loop 231 of axostylus axostyle 23 be snapped in ring grooves 111 in this coating end 11, make both form snapping, the axostylus axostyle 23 unlikely coating ends 11 by coating member 1 of pivot 2 are axially deviate from; At this moment, these axostylus axostyle 23 front ends expose for coating end 11, will keep off tenon 24 then and be intercalated in mortise 233, promptly finish assembling of the present utility model.
Especially, when avoiding coating member 1 with respect to pivot 2 rotation, what produced rocks, be with, please consult Fig. 1 again, the utility model cladding type rotary shaft structure further comprises positioning piece 3, it is to be a lamellar body, this locating piece 3 is axially offered a perforation 31, and it is that axostylus axostyle 23 for pivot 2 wears, and prevents the purpose of rocking when reaching these pivot 2 rotations.And be to make this locating piece 3 can be fixed in a side of this coating end 11, it is provided with a tongue-and-groove 32 corresponding to aforementioned tenon 12 positions, and is intercalated in tenon 12 and fix by this tongue-and-groove 32, this locating piece 3 is adjacent to coat to hold 11 inboard.
So via enforcement of the present utility model, the effect that it gained is, this pivot and coating member are after socket and group are upright, except that the function that due radial friction is provided,, make two unlikelyly to deviate from or separate in addition by the bulge loop of pivot and coat the buckle of the ring groove of end.Moreover this coating member can be in conjunction with positioning piece, make its penetrations adjoin in the side that coats end, in order to wearing of axostylus axostyle, thereby obtains to prevent the effect of rocking.
That the utility model disclosed is a kind of of preferred embodiment, the change of every part or modification and come from technological thought of the present utility model and be have the knack of this technology the people was easy to know by inference, all do not take off claim category of the present utility model.
