The specific embodiment
Below in conjunction with embodiment and accompanying drawing thereof, describe in detail:
Fig. 1 is of the present invention a kind of for the fast clamp mechanism on frame for repairing bicycle.Mainly comprise: be arranged on the fixed mounting 1 on frame for repairing bicycle, one end is fixed on the sleeve pipe 8 on fixed mounting 1 and is fixed on the retaining clip that the fixture block 11 on sleeve pipe 8 other ends forms, one end is inserted into the slip pipe 10 in sleeve pipe 8 and is fixed on the movable clamp that the fixture block 11 on slip pipe 10 other ends forms, outer end is positioned on slip pipe 10 outer ends and is inserted into the screw mandrel 9 in slip pipe 10, be fixed on the adjusting knob 14 on screw mandrel 9 outer end heads, be sleeved on screw mandrel 9 and fixed in position is led screw member in sleeve pipe 8, it is characterized in that: lead screw member and contain inverted U-shaped screw element 5 and the keeper 4 of leading, inverted U-shaped inner side, top of leading screw element 5 is provided with and the corresponding arc internal thread 20 of screw mandrel 9 external screw thread, on the middle side part of keeper 4, offer with inverted U-shaped and lead that the corresponding and top of screw element 5 communicates with the screw mandrel placement hole of keeper 4 and vertical detent 16, the inverted U-shaped screw element 5 of leading utilizes alignment pin 3 to establish to be contained in the detent 16 that keeper 4 offers, keeper 4 utilize the slotted eye 18 being provided with to be sleeved on screw mandrel 9 and fixed in position in the corresponding site of sleeve pipe 8, also comprise establishing being contained in inverted U-shaped return spring 6 of leading screw element 5 tops, be inserted into the quick regulating rod 12 on slip pipe 10 bottoms, be fixed with quick regulating rod spanner 13 fast on the outer end of regulating rod 12, the other end is provided with a convex shaped section.
Described quick regulating rod 12 afterbodys have a convex shaped section, refer to the section of looking as figure
.
Structure chart when Fig. 2 is the quick adjustment state of Fig. 1.When quick regulating rod spanner 13 is pulled to the right, drive the quick regulating rod 12 being fixedly connected with it to rotate, the projection of the convex shaped section arranging on quick regulating rod 12 afterbodys is upwards rotated thereupon, and by inverted U-shaped, lead upwards jack-up of screw element 5 by alignment pin 3, make inverted U-shaped separation with screw mandrel 9 external screw threads with the corresponding arc internal thread 20 of screw mandrel 9 external screw thread that screw element 5 inner sides, top are provided with of leading, make screw mandrel 9 depart from constraint, screw mandrel 9 just can be free to slide in the suit slotted eye 18 of keeper 4, and drive slip pipe 10 freely in sleeve pipe 8, to slide, make to be fixed on a fixture block 11 on slip pipe 10 outer ends as required fast moving put in place, thereby realize the object of the clamp distance of rapid adjustment fixture block 11.
Fig. 4 is the clamp position structure chart of Fig. 1.When quick regulating rod spanner 13 is pulled to the left side end, drive the quick regulating rod 12 being fixedly connected with it to rotate, make the projection of the convex shaped section arranging on quick regulating rod 12 afterbodys turn left thereupon, the inverted U-shaped screw element 5 of leading resets under the effect of return spring 6, make inverted U-shaped the engaging with screw mandrel 9 external screw threads with the corresponding arc internal thread 20 of screw mandrel 9 external screw thread that screw element 5 tops inner sides are provided with of leading, screw mandrel 9 can only be utilized be fixed on the adjusting knob 14 on screw mandrel 9 outer end heads rotation and along with threads turn, and drive slip pipe 10 and the fixture block 11 that is fixed on slip pipe 10 outer ends is shifted thereupon, gripping objects is clamped or unclamped.
For the ease of processing, the keeper 4 of Fig. 6, Fig. 7 is spherical U-shaped part, and the slotted eye 18 of offering on keeper 4 is spherical beaker shape slotted eye; Screw mandrel 9 is inserted in the spherical pore of spherical beaker shape slotted eye 18, and keeper 4 utilizes the spherical pore in the spherical beaker shape slotted eye 18 of offering to be sleeved on screw mandrel 9.Obviously, an also circular hole of described slotted eye 18.
For making the inverted U-shaped screw element 5 of leading be difficult for displacement, guarantee can locate rapidly after screw mandrel 9 fast moving, for quick regulating rod 12 is rotated freely, detent 16 in Fig. 6, Fig. 7 is circular orientation groove, and being provided with arc groove 19 on the middle part, bottom surface of keeper 4, regulating rod 12 is placed in the arc groove 19 being provided with in the middle part of keeper 4 bottom surfaces fast.
In order to ensure screw mandrel 9, can remain duty, cannot detach the inverted U-shaped screw element 5 of leading, for making quick regulating rod 12 the inners can be not sagging because of the effect of return spring 6, guarantee the regulating effect of quick regulating rod 12, in figure, also comprising lives joins the baffle plate 2 being positioned on screw mandrel 9 the inners, and the inner of regulating rod 12 is inserted on the bottom of baffle plate 2 fast.The baffle plate 2 being positioned on screw mandrel 9 the inners is joined in described work, refers to establish be contained on the inner termination of screw mandrel 9 and do not affect the baffle plate 2 that screw mandrel 9 rotates.
In order to ensure the repairing object being tightened, be difficult for loosening or come off, separation with screw mandrel 9 external screw threads even if the inverted U-shaped arc internal thread 20 of leading screw element 5 after screwing is difficult for, the internal retaining surface of the detent 16 in the keeper 4 in figure is 7 font block faces 17.When screwing adjusting knob 14 and fixture block 11 clamped repair object, the inverted U-shaped screw element 5 of leading can abut on 7 font internal retaining surfaces 17 of detent 16 tightly, the projection of 7 font internal retaining surface 17 upper limbs can be pushed down the inverted U-shaped screw element 5 of leading, make the inverted U-shaped screw element 5 of leading be difficult for separation with screw mandrel 9, so, repair object and be difficult for loosening or come off.
