For letting above-mentioned purpose, the feature and advantage of the utility model can be more obviously understandable, elaborate below in conjunction with the embodiment of accompanying drawing to the utility model.At first need to prove; The utility model is not limited to following embodiment; Those skilled in the art should understand the utility model from the spirit that following mode of execution embodied, and each technical term can be done the most wide in range understanding based on the spirit of the utility model.Same or analogous member uses the same reference numerals to represent among the figure.
Like Fig. 3 and shown in Figure 4; The flexible rod positioning device of the utility model one preferred embodiment; 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, a pad 20 and a stopper unit 30.
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, these second clamping plate 124 have one to should centre line L 1 and the perforation 128 relative and one with this positioning hole 127 be located at this 128 1 sides and be the interlocking portion 129 of shrinkage pool shape of boring a hole.This groove 126 is between these first clamping plate 123 and this second clamping plate 124.
This pad 20 is positioned at second clamping plate, 124 outsides of this joint 10; And have an outer side surface opposite 22, one with this second clamping plate 124 opposed inside faces 21, one and this inner side surface 21 to should centre line L 1 and be non-circular register hole 23 and one be located at this inner side surface 21 and be the concavo-convex complementation and the inserted part 24 of inlay card mutually with this interlocking portion 129; This outer side surface 22 is concave arc shape; This register hole 23 is Hexagon, and this inserted part 24 is the projection shape.
This stopper unit 30 has one and extends and be located in the locking bar 31 of this joint 10, a connection piece 32 and a stopper handle 33 that is articulated in this connection piece 32 that is spirally connected with this locking bar 31 along this centre line L 1.
This locking bar 31 has the head 311 and the lock-joining part 312 that is attached at these head 311 1 sides and extends towards these second clamping plate 124 that do not rotate and produce with respect to this first clamping plate 123 along this centre line L 1 location; This head 311 is step shape; And having an expansion position 313 and a card positioning part 314 that is attached at these expansion position 313 1 sides and is plugged in this positioning hole 127 that is arranged in these positioning hole 127 outsides, the cross section of this card positioning part 314 is corresponding to this positioning hole 127.This lock-joining part 312 is linked to this card positioning part 314, is screw shaped and has an outside thread 315.
32 pairs of this connection pieces should second clamping plate 124 and screw lock in this lock-joining part 312; Connection piece 32 cross sections of present embodiment are to should register hole 23 and be the hexagonal column, and have two opposite clamped surfaces 321, a screw 322 and the pivot 323 perpendicular to this centre line L 1 that is spirally connected with this outside thread 315.
This stopper handle 33 can drive this connection piece 32 and rotate with respect to this locking bar 31; And has a pivot part 331 and a pulling part 332 that is attached at these pivot part 331 1 sides that is articulated in this pivot 323; This pivot part 331 has two and presss from both sides built in said clamped surface 321 respectively and supply pin plate that this pivot 323 wears 333, the side face 334 around this pivot 323; This side face 334 is eccentric with respect to this pivot 323 and is provided with; And have one first sidepiece 335 and second sidepiece 336 of being located at these first sidepiece, 335 1 sides; The distance of this second sidepiece 336 to this pivot 323 is greater than the distance of this first sidepiece 335 to this pivot 323, and this pulling part 332 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 332 of this stopper handle 33 is accommodated in this groove 126, and this second sidepiece 336 pushes away this pad 20 of pulling, these second clamping plate 124 towards these first clamping plate, 123 convergences.
As shown in Figure 5 again; When the operator with this pulling part 332 towards this joint 10 outside and certainly this groove 126 shift out; And make this first sidepiece 335 corresponding to this pad 20, this second sidepiece 336 during away from this outer side surface 22; Utilize the difference effect of distance with this first sidepiece 335 to the distance of this pivot 323 of this second sidepiece 336 to this pivot 323; And this locking bar 31 utilizes this expansion position 313 to support to terminate in these first clamping plate 123 and to should centre line L 1 producing the state of location; Can make this second clamping plate 124 relative these first clamping plate 123 produce away from, this fastening portions 12 can produce pine oils to pipe fitting in this 120, and makes that pipe fitting 120 can produce flexible adjustment with respect to this outer tube member 110 in this.
At this moment; If this fastening portions 12 of desire adjustment tighten power the time; The operator directly rotates this stopper handle 33, and this stopper handle 33 can be a center of rotation with this centre line L 1, directly drives this connection piece 32 and produces rotation with respect to this lock-joining part 312; And utilize this connection piece 32 and the register hole 23 of this pad 20 to be non-circular socket; And simultaneously this pad 20 of interlock rotates with respect to these second clamping plate 124, and when being adjusted to required tightness, must make this inserted part 24 in alignment with this interlocking portion 129; Then when pulling this stopper handle 33 and make the outer side surface 22 that 336 pairs of this second sidepieces should pad 20, this pulling part 332 accurately is inserted in and obtains to locate (see figure 4) towards this groove 126.
Therefore, the adjustment of fastening portions 12 tightnesses of the utility model just can be accomplished quite easily, need be with instrument; In addition, utilize this stopper handle 33 directly to drive this connection piece 32 and produce rotation, and this locking bar 31 utilizes this card positioning part 314 to be non-circular socket with this positioning hole 127 with respect to this lock-joining part 312; And can produce the location with respect to these first clamping plate 123; Can avoid this locking bar 31 directly to receive application of force effect, receive the torsional moment effect, can increase the service life, be not easy to damage.
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.
