Embodiment
To shown in Figure 4, basically, the utility model rotating shaft is made up of a male connector 1 and 2 of female connectors like Fig. 1 a.
Male connector 1 is to be combined as a whole by a fixed base 11 and a pivot 12.This fixed base 11 has a sleeve 111, and this sleeve 111 is axially offered an axis hole 112, so as with after chat pivot 12 and combine with fixing with fixed structure.These sleeve 111 non-central axial location, that is eccentric position is provided with a junction 113, shown in Fig. 1 a and Fig. 1 b; This joint 113 is a plate body, and vertically offers at least one attachment hole 114, so that utilize known binding member; After for example screw passes through, and be locked in article, for example body; When only this joint 113 is implemented, do not exceed with aforementioned person, it also must be the non-circular cylinder of a section, so that be socketed in the preset positioning hole of main body.Moreover for forming the preset folding angle of rotating shaft, these sleeve 111 left-hand end side faces axially stretch out a spacing tenon 115.
And the technical characteristics of this fixed base 11 is, is with metallic dust as if it, for example the iron-nickel alloy ejection formation; Its hardness (Rockwell hardness; HRC) be 50-54, pivot 12 hardness of processing with middle carbon quick-turning steel are 37-47 then, make that the hardness of fixed base 11 is hard than pivot 12; Therefore, axis hole 112 inner circle walls of this sleeve 111 are provided with a fixed structure, for example have the embossed portion 116 of burr, and are provided with at least one fixed pan 117 in addition.In addition, these axis hole 112 right-hand ends are communicated with the bigger retaining groove in an aperture 118.
Pivot 12 is a body of rod, and it axially offers the thread hole 121 of a bar body, and at least one oil duct 122 is offered on the surface.These pivot 12 right sides are further prominent establishes an external diameter and is not less than axis hole 112, and as the burr 123 of another fixed structure, and corresponding each fixed pan 117 position are oppositely arranged plane of orientation 124.Wherein, these burr 123 right sides are in abutting connection with a containing groove 125, and its purpose is that when burr 123 was intercalated in the embossed portion 116 of axis hole 112 with the drive fit mode, the metal fragment that both produced can be accommodated in this containing groove 125.
Especially, these containing groove 125 right-hand ends are in addition in abutting connection with first flange 126 of an external diameter corresponding to retaining groove 118, and pivot 12 left-hand end are then dashed forward and established second flange 127 of chatting sleeve joint hole 22 after an external diameter is slightly larger than.
During this male connector 1 combination; At first the plane of orientation 124 of pivot 12 is aimed at the fixed pan 117 of axis hole 112; Then the axis hole 112 of pivot 12 towards fixed base 11 inserted; Make the embossed portion 116 of this axis hole 112 form interlock and interference, thereby burr 123 is fixedly arranged in the axis hole 112 with burr 123 outer circumferential faces; Simultaneously, contact skidding in the time of to avoid pivot 12 rotations by the applying of plane of orientation 124 with fixed pan 117; At last, first flange 126 of these pivot 12 right-hand ends is connected to the retaining groove 118 of sleeve 111 right-hand ends, axially deviates from fixed base 11 to prevent pivot 12, promptly accomplishes the assembling of male connector 1 as shown in Figure 2.
Female connector 2 has a socketed pipe 21, and this socketed pipe 21 is axially offered one and supplied the sheathed sleeve joint hole 22 of pivot 12; Shown in Fig. 1 a and Fig. 1 b, this socketed pipe 21 is the pipe spring of C shape section, and can socketed pipe 21 be divided at least two sections via at least one profile groove 23.For female connector 2 and another article are provided, for example lid is connected, be with, this female connector 2 is provided with a convergence part 24, at least one convergence hole 25 is offered on its surface, so that be fixed in the supporting frame of a lid.In addition.For forming the preset folding angle of rotating shaft, these socketed pipe 21 right-hand end side faces axially stretch out a retaining tenon 26.
See also Fig. 3 and Fig. 4; 2 groups of male connector 1 and female connectors are immediately; Be that the pivot of male connector 1 12 is inserted in the socketed pipe 21 of female connectors 2, and make second flange 127 of pivot 12 left-hand end prop up socketed pipe 21 left end edge, make male connector 1 with female connector 2 unlikely axial disengagements; And pivot 12 is that socketed pipe 21 closely coats; Promptly accomplish the assembling operation of rotating shaft, and the spacing tenon of male and female link 1,2 115 is positioned on the same side face with retaining tenon 26, with control as rotating shaft folding angle.
As shown in Figure 5, be the utility model rotating shaft second embodiment's schematic representation, if this fixed base 11 is with the zinc alloy diecasting moulding, then its hardness will be less than pivot 12; Therefore; The axis hole 112 of this sleeve 111 will not have the setting of embossed portion; But the embossed portion 128 of setting up burr at burr 123 outer circumferential faces; Because the fixed base 11 of this male connector 1 and the combination of pivot 12, and the group of male and female link 1,2 is upright all identical with first embodiment, does not intend at this and giving unnecessary details.
So; Via the enforcement of the utility model, the effect that it gained is, by the fixed base and the pivot of male connector are made respectively; The fixed structure that utilizes both to be oppositely arranged again is combined as a whole; To significantly simplify known integrated male connector production process, except that helping the production capacity lifting, and have the advantage that reduces manufacture cost.Moreover, utilize fixing, plane of orientation formation limited-slip mechanism between this fixed base and pivot, drive pivoted in the time of can avoiding the female connector rotation.In addition, relative stop mechanism on the side face of the socketed pipe adjoining position of the sleeve of this fixed base and female connector is to define the rotation folding angle limits of rotating shaft.Into person is arranged especially, and these pivot two ends are provided with a flange separately, can prevent the axial disengagement with fixed base, socketed pipe respectively, really are a ware big good structure not seen before.
That the utility model disclosed is a kind of of preferred embodiment, the change of every part or modification and come from the technological thought of the utility model and be have the knack of this technology the people was easy to know by inference, all do not take off the claim category of the utility model.
