Abstract
This variable speed bicycle change-speed box adjustment rack, comprise chassis, be vertically fixed on transverse arm that column, level on chassis be fixed on column top, tail end rotate by rotating shaft I install with upper armful ring of transverse arm front end and lower armful of ring, be fixed on the motor 2 on column, fork and the level being installed on motor is installed on the driving lever on fork, the folder hole that after upper armful of ring and lower armful of ring are closed, formation internal diameter and bicycle crossbeam external diameter match, upper armful of ring and lower armful of ring are fixed by screw, when upper armful ring and lower armful of ring clamp after bicycle crossbeam, driving lever contacts with a side crank.Clamp after bicycle crossbeam by folder hole, electric machine rotation drives fork to rotate, fork makes driving lever do circular motion, thereby driving lever is stirred crank circular movement, make the chain of bicycle keep state of kinematic motion, now people can conveniently liberate both hands the change-speed box of bicycle is carried out to quick adjustment work, have facilitated derailleur to regulate the step of change-speed box, have improved efficiency.
Description
Technical field
The utility model relates to variable speed bicycle change-speed box adjustment rack.
Background technology
Along with high-grade derailleur is more and more subject to youthfully to like, increasing youngster selects to ride motion.But the change-speed box of variable speed bicycle need to regularly be adjusted, otherwise just there will be speed change to locate inaccurate problem.But change-speed box need to utilize set screw on screwdriver rotary speed variator on the one hand in the process of adjusting, and also needs on the other hand with the continuous rotating crank of hand, make chain keep state of kinematic motion, when therefore a people operates, there is the inconvenient situation of adjusting.
Summary of the invention
The utility model is in order to overcome the deficiency of above technology, the variable speed bicycle change-speed box adjustment rack that provides a kind of convenience to adjust bicycle speed-varying unit.
The utility model overcomes the technical scheme that its technical matters adopts:
This variable speed bicycle change-speed box adjustment rack, comprise chassis, vertically be fixed on the column on chassis, level is fixed on the transverse arm of column top, tail end by rotating shaft I rotate install with transverse arm front end upper armful ring and lower armful of ring, be fixed on the motor 2 on column, the fork and the level that are installed on motor are installed on the driving lever on fork, the folder hole that after described upper armful of ring and lower armful of ring are closed, formation internal diameter and bicycle crossbeam external diameter match, upper armful of ring and lower armful of ring are fixed by screw, when upper armful ring and lower armful of ring clamp after bicycle crossbeam, described driving lever contacts with a side crank.
For the convenient height that regulates, also comprise along axis direction and be arranged at some teeth on column, rotate and be installed on the fixture block of transverse arm lower end, the block that is arranged at fixture block medial extremity and one end and be fixed on fixture block outside by rotating shaft II, the other end is fixed on the jig arm spring on transverse arm, when in the teeth groove of fixture block between every two teeth, described fixture block medial extremity contacts with block.
The beneficial effects of the utility model are: clamp after bicycle crossbeam by folder hole, electric machine rotation drives fork to rotate, fork makes driving lever do circular motion, thereby driving lever is stirred crank circular movement, make the chain of bicycle keep state of kinematic motion, now people can conveniently liberate both hands the change-speed box of bicycle is carried out to quick adjustment work, have facilitated derailleur to regulate the step of change-speed box, have improved efficiency.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the utility model arrangement for adjusting height structural representation;
In figure, 1. on 2. motor 3. fork 4. driving lever 5. column 6. transverse arms 7. of chassis, embrace ring and embrace ring 9. rotating shaft I 10. folder hole 11. screw 12. tooth 13. teeth groove 14. fixture block 15. rotating shaft II 16. block 17. jig arm springs for 8. times.
Detailed description of the invention
Below in conjunction with accompanying drawing 1, accompanying drawing 2, the utility model is described further.
As shown in Figure 1, this variable speed bicycle change-speed box adjustment rack, comprise chassis 1, vertically be fixed on the One On The Chassis column 5, level is fixed on the transverse arm 6 of column 5 tops, tail end rotates upper armful ring 7 and the lower armful of ring 8 installed with transverse arm 6 front ends by rotating shaft I 9, be fixed on the motor 2 on column 5, the fork 3 and the level that are installed on motor 2 are installed on the driving lever 4 on fork 3, the folder hole 10 that after upper armful of ring 7 and lower armful of ring 8 are closed, formation internal diameter and bicycle crossbeam external diameter match, upper armful of ring 7 and lower armful of ring 8 are fixing by screw 11, when upper armful ring 7 and lower armful of ring 8 are clamped after bicycle crossbeam, driving lever 4 contacts with a side crank.Clamp after bicycle crossbeam by folder hole 10, motor 2 rotating drive forks 3 rotate, fork 3 makes driving lever 4 do circular motion, thereby driving lever 4 is stirred crank circular movement, make the chain of bicycle keep state of kinematic motion, now people can conveniently liberate both hands the change-speed box of bicycle is carried out to quick adjustment work, have facilitated derailleur to regulate the step of change-speed box, have improved efficiency.
As shown in Figure 2, can also comprise along axis direction and be arranged at some teeth 12 on column 5, rotate and be installed on the fixture block 14 of transverse arm 6 lower ends, the block 16 that is arranged at fixture block 14 medial extremitys and one end and be fixed on fixture block 14 outsides by rotating shaft II 15, the other end is fixed on the jig arm spring 17 on transverse arm 6, when in the teeth groove 13 of fixture block 14 between every two teeth 12, fixture block 14 medial extremitys contact with block 16.Can adjust the height of transverse arm 6 according to different bicycle height, while moving up transverse arm 6, fixture block 14 can move and be rotated and compressed jig arm spring 17 simultaneously by rotating shaft II 15 along tooth 12, after adjusting to the right place, jig arm spring 17 drives fixture block 14 to be placed in corresponding teeth groove 13, now under Action of Gravity Field, teeth groove 13 upper surfaces are close in fixture block 14 lower surfaces, and block 16 is close in its side, therefore realize locking.Easy to adjust quick.In the time that needs release moves down transverse arm 6, manually outwards rotate fixture block 14 it is deviate from from teeth groove 13.
