The purpose of this utility model is achieved in that it comprises a rear wheel, one back sprocket wheel, one bicycle back fork, an affixed tie-plate on the wheel hub of the rear wheel outside wherein, the protruding center shaft in the center of this tie-plate reaches around the stay pipe of several evaginations of center shaft, back sprocket wheel is connected on the stay pipe, bicycle back fork with the tail end sleeve on the center shaft outer end, it is characterized in that: on the center shaft outer end of tie-plate, be provided with a hanging set lock, the same radius of the wheel rim of back sprocket wheel is provided with several slotted eyes, hanging set lock mainly comprises lock housing and tapered end again, wherein lock housing is to be formed by connecting by anterior box cover and rear cartridge plate, the box cover stretches out parallel link plate separately respectively with box plate top, this two link plate is set on the center shaft outer end, and the clamping bicycle back fork, the slotted eye sliding fit of the inner of tapered end and back sprocket wheel.
Has a shaft shoulder in the middle of the described tapered end.
Described box cover is provided with a lock core enclosing cover.
Because adopt such scheme: blocking device is fixed in car rear axle and bicycle back fork junction with its lock housing, survivable and dismounting, tapered end directly inserts the wheel rim groove of back sprocket wheel, locks reliable again.
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 the utility model exemplary embodiments cross-sectional schematic.
The A-A cross-sectional schematic of Fig. 2 the utility model exemplary embodiments Fig. 1.
Among the figure: 1, rear wheel, 11, tie-plate, 111, center shaft, 112, stay pipe, 2, back sprocket wheel, 21, slotted eye, 3, rear vehicle fork, 4, hanging set lock, 41, lock housing, 411, the box cover, 4111, link plate, 412, box plate, 4121, link plate, 42, lock core, 43, dead bolt, 44, tapered end, 441, the shaft shoulder, 45, spring, 46, the lock core enclosing cover, 461, link stopper.
Present embodiment comprises a rear wheel 1, a back sprocket wheel 2, a bicycle back fork 3 and a hanging set lock 4, as shown in Figure 1, and wherein:
Rear wheel 1, back sprocket wheel 2 and bicycle back fork 3 all belong to prior art, an affixed tie-plate 11 on the outside wheel hub of this rear wheel 1, the protruding center shaft 111 in the center of this tie-plate 11 (concentric with rear wheel 1 line of centers) stretches out the stay pipe 112 of several evaginations again on the tie-plate 11 of these center shaft 111 peripheries; Back sprocket wheel 2 usefulness screws are connected stay pipe 112 outer faces, and on center shaft 111 outer ends, the wheel rim same radius position of back sprocket wheel 2 is provided with several slotted eyes 21 to bicycle back fork 3 in addition, also belongs to prior art with the tail end sleeve.
Hanging set lock 4 is made up of lock housing 41, lock core 42, dead bolt 43, tapered end 44, spring 45 and lock core enclosing cover 46, shown in Fig. 1~2, wherein:
Lock housing 41 is box hats that anterior box cover 411 and rear cartridge plate 412 usefulness screws link into an integrated entity at box plate 412 rear sides, the link plate 4111 of band through hole is stretched out on box cover 411 tops, box plate 412 tops are also stretched out parallel and band through hole link plate 4121 link plate 4111, and two link plates 4111,4121 segment distances separately, this two link plate 4111,4121 are socketed in center shaft 111 outer ends of tie-plate 11 with its through hole, and bicycle back fork 3 is clamped in this two link plate 4111, (also connect with a nut) between 4121 in center shaft 111 terminations in link plate 4111 outsides of box cover 411, therefore, lock housing 41 can't be dismantled from the center shaft 111 of tie-plate 11 separately, have only dismounting rear wheel 1 (unclamping the nut of center shaft 111 terminations simultaneously) or dismounting tie-plate 11 (band back sprocket wheel 2) just can unload lock housing 41, this moment, motor bike can't be ridden.
Lock core 42 and dead bolt 43 are connected box plate 412 inboards and lock core 42 fore-ends expose box cover 411, as long as plug key and turn key on lock core 42, can make dead bolt 43 skid off or slip into; Tapered end 44 is the straight pins that are provided with a shaft shoulder 441 in the middle of it, expose respectively in the box cover 411 and box plate 412 outsides at its two ends, spring 45 two ends are respectively against the opposite side of box plate 412 inboards and the shaft shoulder 441, make the shaft shoulder 441 against box cover 411 inboards, be that the shaft shoulder 441 is in dead bolt 43 outsides, this moment, the inner of tapered end 44 was in outside the slotted eye 21 that breaks away from back sprocket wheel 2, and promptly motor bike can travel; Have only when inserting lock core 42 with key and screwing and dead bolt 43 is slipped into, press tapered end 44 outer ends simultaneously, the shaft shoulder 441 compression springs 45, make the shaft shoulder 441 be in dead bolt 43 inboards, twisting key again skids off dead bolt 43 to keep out the shaft shoulder 441 and outwards moves, be that the slotted eye 21 of sprocket wheel 2 was motionless after tapered end 44 the inners entered, promptly motor bike can not travel;
Lock core enclosing cover 46 is to be articulated on the box cover 411 on lock core 42 next doors with its eccentric shaft, and at the inner link stopper 461 that connects of this eccentric shaft, and this link stopper 461 is vertical configuration with lock core enclosing cover 46, when the slotted eye 21 of back sprocket wheels 2 is thrown off in tapered end 44 the inners, be that the shaft shoulder 441 is against box cover 411 inboards, rotate above-mentioned eccentric shaft and make lock core enclosing cover 46 horizontal blocking outside lock core 42 positions, put against the shaft shoulder 441 inboards and link stopper 461 is just in time perpendicular, can prevent that on the one hand earth enters lock core 42 slotted eyes (inserting the slotted eye of key), the inner that can prevent tapered end 44 on the other hand is subjected to unexpected power (as: cyclist's pin bump, sharp pounding etc. in travelling), make tapered end 44 inside compression springs 45, and enter in the slotted eye 21 of back sprocket wheel 2, cause dangerous accident.
