Description
Technical field
The utility model is a kind of turning shaft structure, and the tenon dogging that refers to a kind of internal axle sleeve especially is buckled in the access slot of outer sleeve of a fixed block, makes both need not be by being fixed by impact style, and then the turning shaft structure of reduction assembling procedure.
Background technique
The consumption electronic products of general tool flip, such as portable computer, mobile phone, e-dictionary and portable video-audio playing device ... etc., be that main part is placed Lower Half mostly, and link by the cover body part of the rotating shaft and the first half, make cover body part with respect to main part, the folding that can be.Therefore, rotating shaft is the good corrupt big essential factor of decision the said goods.In fact, good rotating shaft except that the stagnation effect of indispensability, makes its not reason repeatable operation and produce laxly, certainly in operation, also should eliminate different sound, the time feels bad in operation to avoid the user.
By and large, traditional socket joint type rotating shaft is for obtaining desired stagnation locating effect, precision requirement is very high, it mainly forms an axis hole on a female connector, and the jack-post level of male connector runs through grooving to offering one, so that provide this jack-post suitable elasticity so that embed axis hole, make friction torque be formed on jack-post and axis hole between.And preceding existence of taking off jack-post because of grooving so that the friction position of this jack-post in axis hole between the grooving two ends vertically to, when repeatable operation, this two friction parts bit loss consumption is exceedingly fast, and then causes relaxing.
Based on many disappearances of preceding taking off the socket joint type rotating shaft, for example shown in No. the 420321st, the TaiWan, China patent announcement, this pivot includes: a fixed base, a plurality of spoon rack, a positioning plate and a pivot are formed, be formed with joining hole, worker's shape groove and one group of block on this fixed base respectively, in joining hole and worker's shape groove, spoon rack can be set, and be formed with axis hole in this spoon rack, the rotating shaft with oil groove of pivot can penetrate in the axis hole, and rotating shaft can penetrate one to have in the positioning plate of fanning strip, so that when rotating, this spoon rack then countershaft forms friction torque.No doubt, this pivot can obtain desired stagnation locating function, and only its significant disappearance is, the reed pipe frame of this case is to adopt plural number setting, often increases the operation and the complexity of assembling.In addition, in the patent specification of this prior art, disclose this reed pipe frame and between between one group of end, be formed with a breach respectively, and the seat of breach can supply fixed base is squeezed into salient point with being, with and breach between certain location is provided.Be this combination, except that the drive fit intercalation of need necessity, the fixed base after needing in addition will make up one by one and spoon rack with impact style with both further combined with, not only labor intensive and man-hour, and the extra degree of difficulty of assembling that increases really are locating of blemish in an otherwise perfect thing.
In view of this, the utility model claimant this in the experience of being engaged in rotating shaft design and production and marketing for many years, the phase can overcome many disappearances of aforementioned rotating shaft, through experiment and test repeatedly, and then develops and " turning shaft structure " of the present utility model.

Embodiment
As shown in Figures 1 to 4, basically, turning shaft structure of the present utility model is by a fixed block 1, one internal axle sleeve 2, and a movable part 3 combines.Wherein, be somebody's turn to do the operating state of " activity " and " fixing " and unrestricted above-mentioned two assemblies, when implementing, this movable part 3 also can be maintained fixed state, but produces spinning movement by fixed block 1.
Fixed block 1 is a support body, and it has a junction 11, and for being incorporated into article, such as main part, this joint 11 has at least one conjugate foramen 111 as shown in the figure, so that utilize existing coupling unit, after for example screw passes through, and is locked in article.Only not as limit, this joint 11 can be tool and mills face cylinder, triangular prism, tetragonal prism ... etc. the polygon cylinder, but so that intercalation and be positioned article.
And joint 11 1 sides are extended an outer sleeve 12, it axially opens an axis hole 121, this axis hole 121 radial communication one caulking groove 122, and creative feature of the present utility model is, these caulking groove 122 side direction are opened at least one access slot 123, as shown in the figure, and a pair of access slot 123 that is a straight line of these caulking groove 122 bottom side extendings, only not as limit, this two access slot 123 also can be high low head setting according to actual demand.
These 31 stage casings, convergence part are provided with an axle collar 32, it is as the usefulness of contact when combining with outer sleeve 1, it axially extends a jack-post 33 in addition, it is to being provided with a groove 331 in profile groove 21 positions, make both sides form a friction section 332 respectively, each friction section 332 surface has a curvilinear oil groove 333, so that supply the ccontaining of lubricant grease, so that lubricated effect to be provided.In addition, these jack-post 13 front-end edges are provided with a chamfered section 334, in order to being intercalated in this bunching ring 22.
The utility model group immediately, at first the bunching ring 22 and the tenon hook 231 of this internal axle sleeve 2 are aimed at respectively and be inserted in the drive fit mode along axis hole 121 and access slot 123, each bunching ring 22 and frame sheet 23 are socketed on respectively in the axis hole 121 and caulking groove 122 of outer sleeve 12, the tenon hook 231 of these sheet 23 forward and backward surperficial two reverse projections is then according to its special sagittal appearance, can be intercalated in smoothly in the corresponding access slot 123, and by being snapped in the tenon hook 231 by its high rear end of rising, and unlikelyly axially deviate from, internal axle sleeve 2 firmly can be installed in the outer sleeve 12.At this moment, sleeve 2 in again this jack-post 33 being intercalated in the drive fit mode lays respectively in the corresponding bunching ring 22 each friction section 332, promptly finishes of the present utility model group and stands.During enforcement, then the convergence part 31 of the joint 11 of fixed block 1 and movable part 3 is installed in the support 4 of main part and cover body part respectively.
So via enforcement of the present utility model, its effect of obtaining is that this internal axle sleeve is one-body molded, but not the segmentation setting except that the quantity of reduction assembly, and is simplified the operation of assembling.Into person is arranged especially, of the present utility model sheet is to be intercalated in the caulking groove, make bunching ring moving partially about unlikely in axis hole, in addition by vertically to the tenon dogging pull in access slot, can guarantee bunching ring unlikely dandle in axis hole, thereby obtain both combinations firmly, make movable part when rotating, can obtain comparatively stable friction torque.Simultaneously, by can ccontaining lubricant grease by the oil groove setting of friction section, making the comprehensive lubrication effect of acquisition between jack-post and bunching ring, to eliminate because of the dry and astringent different sound that is produced, really is a big good structure of ware.
That the utility model disclosed is a kind of of preferred embodiment, and patent right category of the present utility model is not all taken off in Ju Bu change or modification and come from technological thought of the present utility model and be easy to the person of knowing by inference by the people who has the knack of this skill such as.
