Like Fig. 3 and shown in Figure 4; The flexible rod positioning device with elastic keeper of one first preferred embodiment of the utility model; An outer tube member 110 and interior pipe fitting 120 socket places of being installed in mutual socket and can stretching relatively, and comprise a joint 10, elastic keeper 20, a pad 30 and a lock cell 40.
This joint 10 has the fixing part 11 and the fastening portions 12 that is connected these fixing part 11 1 sides along an axis L that are installed in these outer tube member 110 ends.This fastening portions 12 have one around this axis L and can produce leg 122 that side direction is an open endoporus 121, one be linked to this leg 122 wherein first clamping plate 123, one of a lateral margin be linked to these leg 122 another lateral margins and relative with this first clamping plate 123 second clamping plate 124, one be arranged between these first clamping plate 123 and these second clamping plate 124 and the line of rabbet joint 125 and a groove 126 that centers on this axis L and be arranged with of being communicated with this endoporus 121 by an outer side surface.These first clamping plate 123 have one along extending perpendicular to the centre line L of this axis L 1 and be non-circular positioning hole 127, and these second clamping plate 124 have one to should centre line L 1 and the perforation 128 relative with this positioning hole 127.
This elastic keeper 20 has and contains the elastic force that flicks relatively after making this first clamping plate 123 and these second clamping plate, 124 pressurizeds; Be installed in the fastening portions 12 of this joint 10; The elastic keeper 20 of present embodiment processes with the rubber-like sheetmetal; And direct heeling-in is on the leg 122 of this joint 10; And have one and establish and adjacent to the loop portions 21 of this endoporus 121 along this leg 122 rings, the argument of this loop portions 21 is greater than 180 degree, and has two side ends 211,212 that correspond respectively to these first clamping plate 123 and these second clamping plate 124.
This pad 30 is positioned second clamping plate, 124 outsides of this joint 10, and has one to should centre line L 1 and be non-circular register hole 31, and this register hole 31 is Hexagon.
This lock cell 40 have a locking bar 41 that is located in these first clamping plate 123, this second clamping plate 124 and this pad 30 and one be articulated in this locking bar 41 and can these second clamping plate 124 of stopper with respect to these first clamping plate 123 produce convergences or away from stopper handle 42.
This locking bar 41 has one and does not rotate and produce location rod member 411 and of location and the binding rod member 412 of these location rod member 411 screw locks along this centre line L 1 with respect to this first clamping plate 123; This location rod member 411 is positioned the positioning hole 127 of these first clamping plate 123; This binding rod member 412 can move and be located in the register hole 21 and this perforation 128 of this pad 30 along this centre line L 1; And has a pivot 413; This stopper handle 42 can drive and should link rod member 412 with respect to these location rod member 411 rotations; And have a pivot part 421 and a pulling part 422 of being located at these pivot part 421 1 sides that is hubbed on this pivot 413, and this pivot part 421 has one and centers on the side face 423 that this pivot 413 is eccentric setting, and this pulling part 422 can be accommodated in this groove 126.
And it is as shown in Figure 4; 12 pairs of fastening portions that show this joint 10 should be tightened in interior pipe fitting 120 generations; And make the state that pipe fitting 120 is located with respect to these outer tube member 110 generations in this, at this moment, the pulling part 422 of this stopper handle 42 is accommodated in this groove 126; And this pad 30 of side face 423 stoppers of this pivot part 421, these second clamping plate 124 are towards these first clamping plate, 123 convergences; This fastening portions 12 produces the gap smaller of resiliently deformables, this line of rabbet joint 125, and the metamorphosis that this elastic keeper 20 receives this fastening portions 12 also produces resiliently deformable, and contains back the elastic force of releasing.
As shown in Figure 5 again; When the operator with this pulling part 422 towards this joint 10 outside and certainly this groove 126 shift out; And make the press power of 423 pairs of these pads 30 of this side face release except that the time, utilize the effect of releasing of returning after this fastening portions 12, these elastic keeper's 20 resiliently deformables, should centre line L 1 produce the state of location on 123 pairs on this locking bar 41 and these first clamping plate; Can make these second clamping plate, 124 relative these first clamping plate 123 automatically spring open; It is big that the gap of this line of rabbet joint 125 becomes, and this fastening portions 12 can produce pine oil to pipe fitting in this 120, and make this interior pipe fitting 120 produce flexible adjustment with respect to this outer tube member 110.
Therefore; The utility model utilizes this elastic keeper's 20 setting, can make this fastening portions 12 receive this lock cell 40 and pull and press and produce resiliently deformable, the pressure of pulling release except that the time; These first clamping plate 123 are flicked with these second clamping plate 124 automatically relatively; Just can return back to original state, and avoid producing permanent deformation behind fastening portions 12 pressurizeds of this joint 10, not only simple in structure and can reach the flexible rod adjustment and be easy to purpose.
Fig. 6 and shown in Figure 7 for another example; The utility model second embodiment and first embodiment are roughly the same, and difference is: this elastic keeper 20 ' also have one be attached at this loop portions 21 ' wherein a side end 211 ' and extend to the first inboard diving board 22 ' of this first clamping plate 123 and one be attached at this loop portions 21 ' end side 212 ' and extend to the second inboard diving board 23 ' of this second clamping plate 124.Utilize cooperating of this loop portions 21 ' and this first diving board 22 ' and this second diving board 23 ', more can add and contain the elastic force that flicks relatively automatically after forcing these first clamping plate 123 and these second clamping plate, 124 pressurizeds.
And for example shown in Figure 8; The utility model the 3rd embodiment; Mainly be with this elastic keeper 20 " directly heeling-in is at this joint 10 " leg 122 " inside; and this elastic keeper 20 " with this endoporus 121 " between wall thickness of generation, present embodiment also can be reached purpose same as the previously described embodiments and effect.
As shown in Figure 9 more again; The utility model the 4th embodiment is similar to first embodiment; Be with first embodiment's difference: this elastic keeper 200 also has a retaining edge 240 that is radially extended outwardly by these loop portions 210 sides; This retaining edge 240 is kept out in the side end face of this fastening portions 12 in contrast to this fixing part 11; By the setting of this retaining edge 240, can make this elastic keeper 200 produce the location with respect to this joint 10, and this elastic keeper 200 can compel the cover mode and is positioned on the leg 122 of this joint 10 along this axis L.
Below described the preferred embodiment of the utility model in detail; But it will be appreciated that; After having read the above-mentioned teachings of the utility model; Those skilled in the art can do various changes or modification to the utility model, and these equivalent form of values fall within the application's appended claims institute restricted portion equally.
