The specific embodiment
Below in conjunction with the specific embodiment the utility model is described in further detail:
Shown in one of Fig. 1-3, the utility model comprises chain wheel cover 1, lockset 2 and sprocket wheel 3, and described sprocket wheel 3 centre holes are fixedly mounted on the axle drive shaft 4 of motor bike, are mounted with lock collar 31 on sprocket wheel 3 end faces, and lock collar 31 is provided with plural lockhole 32; Chain wheel cover 1 is fixed on the motorbike frame, is provided with the lock chamber 11 of circular bulge loop in it, and lockset 2 is located in the lock chamber 11, and the circle wall in lock chamber 11 is provided with the knock hole of inserting out for the lock pin 21 of lockset 2 12; Lock collar 31 is placed in outside the lock chamber 11, and when lockset 2 was locked, the lock pin 21 of lockset 2 passed the knock hole 12 in lock chamber 11, inserted in the lockhole 32 on the lock collar 31.
Described lockset 2 comprises lock frame 22, latch 23 and lock pin 21, lock frame 22 wears chain wheel cover 1 and lock chamber 11 walls successively, and lock frame 22 1 ends are retained in outside the chain wheel cover 1, and the other end extends in the lock chamber 11, the end is provided with first retracing spring, 5, the first retracing springs 5 and leans lock chamber 11 inwalls; The side that lock frame 22 extends in the lock chamber 11 is fixed with triangle pushing block 6, and lock pin 21 slides along knock hole 12 directions and is located at triangle pushing block 6 hypotenuses one side, and is promoted by this hypotenuse, and the corresponding lock pin 21 of chain wheel cover 1 inwall is provided with chute 13; Lock pin 21 is provided with second retracing spring 7 by the hypotenuse end, and the other end is provided with lock house 25, and when lockset 2 was locked, dead bolt 25 passed the knock hole 12 in lock chamber 11, inserted the lockhole 32 of lock collar 31; The opposite side that lock frame 22 extends in the lock chamber 11 is provided with first positioning groove 26 and second positioning groove 27, and latch 23 corresponding first positioning grooves 26 are arranged on lock chamber 11 opposite sides, and chain wheel cover 1 corresponding latch 23 is provided with the structure 28 of unblanking.
One end of described latch 23 corresponding lock chambeies 11 inwalls is provided with the 3rd retracing spring 29, and the corresponding latch 23 of chain wheel cover 1 inwall is provided with another chute 14.
The described structure 28 of unblanking comprises lock core 281, lock core 281 is located at and locks on the chain wheel cover 1 of frame 22 perpendicular directions, lock core 281 is provided with shifting block 282, latch 23 correspondences are set ahead and are provided with allocating slot 283, by the shifting block 282 on the key rotary locking cylinder 281 drive lock cores, and then drive latch 23 moves around along first or second positioning groove, 26,27 directions.
The lock frame of the insertion end of described first positioning groove, 26 corresponding latches 23 presses down surface 261 and is provided with lead angle.Adopt such structure, can directly point depress the lock frame 22 lock, simple to operate, lock and need not use key.
The hypotenuse end of described lock pin 21 relative triangle pushing blocks 6 is provided with pulley 24.
Also be provided with in the described lock chamber 11 and motor bike shutdown systems bonded assembly flameout switch 8, the corresponding flameout switch 8 of the other end that lock frame 22 extends in the lock chamber also is provided with the pushing block 9 that promotes flameout switch 8.When lock frame 22 moved down, it is flame-out that pushing block 9 drives flameout switch 8, pins ignition system.
Adopt above scheme, when motor bike is locked, firmly press down lock frame 22, insert second positioning groove 27 of lock frame 22 until the end of latch 23, lock frame 22 location.Lock frame 22 moves down in the process, and it is flame-out to drive flameout switch 8, pins ignition system.Simultaneously, triangle pushing block 6 hypotenuses of locking frame 22 1 sides promote the pulley 24 of lock pin 21, thereby it is moving to lock chamber 11 wall shifts to drive lock pin 21, and the dead bolt 25 on the lock pin 21 passes the knock hole 12 of locking chamber 11 and the lockhole 32 that stretches into lock collar 31.At this moment, when if fruit dead bolt 25 does not insert the lockhole 32 of lock collar 31, dead bolt 25 shrinks to lock pin 21 inner chambers, second retracing spring 7 in the compressing lock pin 21, second retracing spring 7 in the lock pin 21 applies an outside top power can for dead bolt 25, and when sprocket wheel 3 rotations, the lockhole 32 on the lock collar 31 forwards dead bolt 25 belows to, the top power of second retracing spring 7 makes dead bolt 25 insert lockhole 32, finishes automatically locking.
When motor bike is unblanked, clockwise rotate lock core 281, thereby the 282 drive latches 23 of the shifting block on the lock core 281 deviate to lock second positioning groove 26 on frame 22 opposite sides, first retracing spring, the 5 jack-up lock frame 22 of lock frame 22 ends, dead bolt 25 outer sheathed springs promotion lock pins 21 inwardly move and break away from lock collar 31, and lock frame 22 is gone up the spring-go positions automatically, and then drive lock pin 21 resets, dead bolt 25 on the lock pin 21 withdraws from the lockhole 32 of lock collar 31, realizes the motor bike process of unblanking.Last another mistake hour hands revolve lock pin 21 and turn 90 degrees, and latch 23 falls into first positioning groove 26 of lock frame 22, extracts key again.
