Relatively；Including lock body spine flap, a pawl seat, a ratchet, a pawl, two pawls, lock core shifting block；
It is hollow structure that the pawl seat, which is fixed on vehicle frame, and a pawl and two pawls are symmetricly set in pawl seat
Portion, one end connect swingable with pawl seat, and the other end is provided with more than one ratchet and is correspondingly arranged on a reset respectively
It is connected inside spring and two resetting springs and pawl seat；
On pawl seat, middle part is placed on foot-operated axis left end and has certain sky with foot-operated axis the spine flap fixed cover
Between so that foot-operated axis can rotate wherein；
The lock body is arranged on spine flap, wherein the lock core shifting block is between a pawl and two pawls；
The ratchet is fixedly attached to foot-operated axis left end, irremovable；The pawl seat is arranged on the ratchet periphery
And and coaxial ratchet.
Further, the foot-operated axis left end is set as cube structure, is provided with and described cube in the middle part of the ratchet
The square hole of body matching is simultaneously socketed on the cube；The left side of the ratchet, which is provided with check ring, prevents the ratchet left
It moves right.
Advantageous effect：
The present invention is wholy set in inside bicycle, is coordinated with exterior latch during use, even if in bicycle exterior latch
In the case of being destroyed, since the present invention locks bicycle pedal central axis so that bicycle still cannot use, preferably
Play antitheft effect.

In figure：1 foot-operated axis, 2 lock bodies, 3 spine flaps, 4 pawl seats, 5 ratchets, 6 one pawls, 7 lock core shifting blocks, 8 two pawls,
Big flywheel, 12 rear flywheel, 13 check ring are ridden in 9 one resetting springs, 10 2 resetting springs, 11
Specific embodiment
Below with reference to the embodiments and with reference to the accompanying drawing being more specifically described to technical scheme of the present invention, need
Bright is that the "left", "right" occurred in claims of the present invention, specification etc. refers to the process of be ridden in bicycle
In orientation shown in the orientation identical with human body or attached drawing；And " level ", " vertical " are when referring to bicycle normal stand
Relative to the orientation on ground.
As shown in Figure 1, 2, a kind of theft-proof device for bicycle of the present invention includes one group of ratchet mechanism, outside the ratchet mechanism
Structure includes lock body 2, the ratchet 5 of pawl seat 4, one of spine flap 3, one, and the ratchet mechanism is integrally socketed in foot-operated axis 1
On, the pawl seat 4 is fixed on vehicle frame, and 4 inside of pawl seat is hollow structure, and the ratchet 5 is in the spine
Inside wheel seat 4.
On the pawl seat 4, the lock body 2 is arranged in the base seat lid 33 fixed cover of spine flap.The spine
The middle part of flap 3 be provided with the foot-operated 1 corresponding trepanning of axis, and there are certain spaces with the foot-operated axis 1, ensure foot-operated
Axis 1 is free to rotate in the trepanning.
The ratchet 5 is fixedly attached on the foot-operated axis 1, irremovable.
As shown in figure 3, the pawl seat 4 is internally provided with a pawl 6 and two pawls 8,6 and two pawl 8 of a pawl
One end is connected on the inner wall of the spine seat 4 and can freely swing, and the other end is provided with more than one ratchet.The spine
A resetting spring 9 and two resetting springs 10 are additionally provided with inside seat 4, a resetting spring 9 is consolidated with two resetting springs, 10 one end
It is scheduled on 4 inner walls of the spine seat, the other end is connected respectively with a pawl 6 with two pawls 8.
The lock body 2 further includes lock core shifting block 7, and the lock core shifting block 7 is arranged among two pawls, when lock body 2
When being inserted into key and being torqued into open position, the lock core shifting block 7 is in horizontal position, can push 6 and two pawl 8 of a pawl
So that a pawl 6 is detached with two pawls 8 with the ratchet 5, foot-operated axis 1 described at this time is unrestricted free to rotate,
Car is rideable.
When the key in the lock body 2 is torqued into locked position, the shifting block 7 is in vertical position, a pawl 6 and two
Pawl 8 is engaged in a resetting spring 9 under the promotion of two resetting springs 10 with the ratchet 5, at this time ride axis 1 by
