Be that the utility model is described in further detail in conjunction with the accompanying drawings below: referring to Fig. 1 is that conduction mechanism is always schemed, assembling core dish 3 and two pads 4 on the supporting seat 5, having the porose disc 1 usefulness steel ball 2 of dialling arm is assemblied between supporting seat 5 and the core dish 3, border small square hole and supporting seat 5 middle gears 7 are done the conduction engagement in the porose disc 1, be riveted on to have in the axle sleeve 6 of supporting seat 5 bottoms and rotate square hole axles 8 with gear 7, square hole axle 8 lower ends are done conduction with flexible axle 9 square toes and cooperated, and are fixing by fastening cap 21.Referring to Fig. 2, it is Fig. 1 K-K cut-open view, the core dish 3 and supporting seat 5 centers that are assembled into one among the figure are that through hole is assemblied on the bicycle front axle, when the rotation of bicycle front-wheel is advanced, to stir porose disc 1 and rotate thereupon, the speed of wheel and the number of turns are by porose disc 1, gear 7, square hole axle 8 and flexible axle 9 outputs.Flexible axle 9 other ends connect instrument, referring to shown in Figure 3, in like manner, flexible axle 9 drives main shaft worm screw 45 through square hole axle 8 and rotates, main shaft worm screw 45 during with the wheel information of same to the fast mechanism of meter, total counter, but return-to-zero counter transmission, in the fast mechanism of meter, referring to Fig. 3 and Fig. 5, the assembling of main shaft worm screw 45 upper ends has the antimagnetic permanent magnet 24 that takes off magnetic shell, and this shell is to do permanent magnet 24 tops with aluminum, the rotating needle pivot 41 of framework lamina tecti 42 assemblings, the anti-magnetic that its lower end fixed random magnet 24 magnetic are rotated takes off that magnetic is moving to cover 54, makes other part in the instrument not be subjected to the magnetic interference of magnet 24, guarantee vehicle ' meter speed accurately, it is moving to cover 54 and also is made from aluminum.Assembling damper 13 and hairspring 25 in the needle pivot 41, needle pivot 41 upper end fixed pointers 11, when bicycle advanced, the rotation speed change of wheel drove magnet 24 and rotates variation through flexible axle 9, main shaft worm screw 45, make the moving lid 54 that rotates certain limited angle with magnetic, drive pointer 11 swings, thereby on dial plate 12, show, referring to Fig. 4, pointer 11 corresponding scale marks 32 and speed refer to vitta 33, promptly know the variation of the bicycle speed of a motor vehicle.

Referring to Fig. 3 and Fig. 5, but at the assembling of rotating main shaft worm screw 45 both sides corresponding total counter and return-to-zero counter.In the total counter, main shaft worm screw 45 and 19 engagements of tale one-level worm and wormwheel, worm and wormwheel 19 meshes with tale second-stage worm worm gear 18 again, worm and wormwheel 18 is through meshing with tale intermediate setting wheel 17, driving tale linked gear 31 rotates, linked gear 31 drives total counter rotating disk 26 countings that assemble on the axle 40, and the spider gear 43 that yet drives simultaneously in the rotating disk 26 does not return zero rotation, thereby the each distance accumulative total of walking of bicycle is presented on the dial plate 12.But in return-to-zero counter, main shaft worm screw 45 and time zero one-level worm and wormwheel, 47 engagements, worm and wormwheel 47 meshes with time zero second-stage worm worm gear 46 again, worm and wormwheel 46 rotates through driving back zero linked gear 38 with time zero intermediate setting wheel, 39 engagements, linked gear 38 drives return-to-zero counter dial rotation counting, also drive the spider gear 36 that to stir simultaneously and rotate, thereby the demonstration short distance can be returned zero count on dial plate 12.Manually return-to-zero mechanism is like this, referring to Fig. 5, assembling can be through the bearing 50 of axle 49 swings on the axle of fixing on the core framework 48 49, assembling spider gear 36 in the axle 52 on the bearing 50, bearing 50 ends are done back zero with time zero count rotating disk 14 and are cooperated, assembling return torsion spring 51 between the diaxon 49 and 52, be fixed on the camshaft 53 in the core framework 45, assembling cam 37 is done displacement with axle 52 and is cooperated, when stirring back zero turn-knob 27, make the spider gear 36 on the axle 52 break away from back zero linked gear 38, make the swing of bearing 50 ends make the return-to-zero counter rotating disk return zero rapidly simultaneously, so that have the records of distance by the log again next time.When hand left knob 27, under torsion spring 51 effects, spider gear 36 returns and linked gear 38 engagements began so again to have the records of distance by the log next time.

For the cyclist is provided more convenience, core framework 48 outside wiring harness plates 23 provide electric energy by dry cell in the power pack 22, press microswitch 28 and 29, just can be regularly, timing, when bicycle running after certain schedule time, piezoelectric buzzer 30 sends 30 seconds buzzers, simultaneously luminotron 34 luminous demonstrations, referring to Fig. 3 and Fig. 4, irradiation opens the light and 16 makes fluorescent tube and show, so that the user watches instrument night, and grasp speed, time.

Advantage of the present utility model and effect are as follows:

1, the user transmits owing to adopting in the conduction mechanism to roll, so can refuel resistance and the wearing and tearing of having avoided dry friction to bring, the service life of having improved part at any time.

2, adopt totally-enclosed magnetic strength meter speed in the instrument, solved instrument and be subjected to magnetic interference and take off magnetic phenomenon to take place.

3, owing to adopt double counter in the instrument, so the user need not calculate, see intuitively that just mileage tale and short square are from the disposable counting of mileage.

4, instrument adopts electronics and machinery to combine, then have meter speed, have the records of distance by the log, restorable is had the records of distance by the log, time showing, timing and light, the sound show, stopwatch preliminary election and scale, pointer plating fluorescence display multi-function action, is fast the counting of the matching used multi-functional meter of bicycle The journey device.

5, on probation through manufacturing experimently, respond well, reach designing requirement.
