Embodiment
Relevant feature of the present utility model and technology contents see also following detailed description and accompanying drawing, yet accompanying drawing only provides reference and explanation, is not to be used for the utility model is limited.
Consult shown in 2 figure, the utility model provides a kind of pivot structure, and pivot 1 mainly comprises peg graft axle 10, socket tube 20, wherein:
The axle 10 of pegging graft has fixing part 11 and protrudes out the portion of inserting 12 of formation from fixing part 11 1 ends, insert portion 12 and comprise the body of rod 121 that is connected in fixing part 11 and the spheroid 122 that stretches out and expand from the body of rod 121, the radially outer edge diameter of spheroid 122 is greater than the radially outer edge diameter of the body of rod 121, and is axially arranged with opening profile groove 13 at spheroid 122 and the body of rod 121.In addition, be provided with cylinder 14, to increase the socket stability of pegging graft between axle 10 and the socket tube 20 in the connecting part of the fixing part 11 and the body of rod 121.In addition, spheroid 122 is provided with two mutual parallel end faces 123 in the direction perpendicular to profile groove 13, to reduce the area of contact between spheroid 122 and the socket tube 20 and to be easy to spheroid 122 is inserted socket tube 20 windings.Moreover, respectively be provided with into oily fillet 124 in the connecting part of spheroid 122 with end face 123, being beneficial to lubricant oil can enter and sufficient lubrication from here.
Consult Fig. 3, Fig. 4 and shown in Figure 5, it is respectively the axle of pegging graft of the present utility model packed into the schematic representation of socket tube and along the sectional view of Fig. 4 center line 5-5 of the schematic representation of socket tube, the axle of pegging graft of not packing into as yet.During combination, the portion of inserting 12 of the axle 10 of pegging graft is forced to push in the receiving hole 23 of socket tube 20, inwall week disc by receiving hole 23 presses the outer edge surface of spheroid 122, and makes profile groove 13 front ends of the axle 10 of pegging graft produce inside resiliently deformable, so that spheroid 122 is pulled in receiving hole 23 by elastic clip.Contact kenels because contacting between the internal face of spheroid 122 and receiving hole 23 is two discontinuous lines, so the external profile diameter of spheroid 122 only processes in the turning mode and get final product, can significantly omit the abrasive machining of known technology; And by the setting of going into oily fillet 124, in rotation process, can oil mass be sent between the surface of contact of spheroid 122 and receiving hole 23 easily, thereby the lubrication effect of increase pivot 1, and prolong its working life.
See also Figure 6 and Figure 7, it is respectively the combination schematic representation that the utility model is applied to digital camera and mobile computer, and pivot 1 of the present utility model can be installed on digital camera, mobile computer, liquid crystal display, hand held CD-ROM drive or other the various electronic equipments.Electronic equipment 4 has main frame 41 and lid 42, screw can be penetrated the peg graft locking hole 111 of axle 10 and the locking hole 211 of socket tube 20 respectively, locks respectively on the main frame 41 and lid 42 of electronic equipment 4 again.When lid 42 is upwards started, the axle 10 of pegging graft rotates with respect to socket tube 20, because its area of contact to each other is little, so only need apply less initiation power, can gently lid 42 be started, and engage the location mutually by the fastening part (figure does not show) of 42 of main frame 41 and lids along ground.
See also shown in 8 figure, be another embodiment's of the utility model assembled sectional view.Wherein the body of rod 121 at the axle 10 of pegging graft is provided with grab 125 near on fixing part 11 1 sides, and the inwall of the receiving hole 23 of socket tube 20 then is provided with groove 24 near opening end.Groove 24, is obtained good butt joint effect, thereby can be prevented the break-off in the rotation process so that peg graft axle 10 when being connected in socket tube 20 corresponding to aforesaid grab 125 location fastenings, and can promote the smoothness when pivoting.
In sum, the utility model can omit the abrasive machining processing procedure of pivot, thereby significantly cut down finished cost by the pivot structure is improved; And can increase oil mass and infiltrate between the surface of contact of spheroid and receiving hole, to promote lubrication effect and to prolong its working life.
Yet, the above only is a preferred possible embodiments of the present utility model, be not so promptly limit to claim of the present utility model, so the equivalent structure that all utilization the utility model specifications and accompanying drawing content are carried out changes, or directly or indirectly be used in other relevant technical field, all in like manner all be contained in the scope that the utility model contains.
