The specific embodiment
As Fig. 1, Fig. 2 and shown in Figure 7, the utility model comprises: brake for motorcycle lid 1, be installed on the lock core 2 on the brake for motorcycle lid 1, and lock core 2 nationality pins 13 are fixed on the brake for motorcycle lid 1.Connect a linkage taper lock gear 3 on the lock core 2 by key control, taper lock gear 3 with can serve as that tongue driving device dead bolt driven wheel 5 interactions of axle rotation are connected with hub of motorcycle axle core 4.4 dead bolts 6 are installed in the dead bolt pilot hole that is located at the dead bolt frame 7 on the brake for motorcycle lid 1 between mutually equidistantly, and the bottom of each dead bolt 6 is equipped with dead bolt operating spring 12, is provided with the reinforcement steel bushing in the dead bolt pilot hole of dead bolt frame 7.Be uniform-distribution with the cycloid 51 of 4 fin shapes on the dead bolt driven wheel 5, the end of cycloid 51 is provided with safety groove 511, dead bolt 6 is provided with and dead bolt driven wheel cycloid 51 corresponding concavity groove (not shown), concavity groove and cycloid 51 tablings, make dead bolt 6 do moving of flexible shape along cycloid 51, reach the purpose that shuts, unblanks along with the rotation of dead bolt driven wheel 5.Be provided with lockhole ring 8 on hub of motorcycle axle core 4, lockhole ring 8 is provided with the dead bolt hole that can hold dead bolt 6 with dead bolt 6 corresponding positions.
The tamper spline shift fork 10 (seeing Fig. 5, Fig. 6) that is provided with groove 9, a bidentate in the drg axis hole is installed in the motorcycle bottom fork outside, and its bidentate is installed in the groove 9 by teeth groove 17 is installed; An anti-rotating pin 11, one end are positioned at described groove 9, and the other end is connected in the kinematic mechanism by key control; Kinematic mechanism is a helicoidal gear, at first the internal diameter of dead bolt driven wheel 5 is provided with spiral, and the end of anti-rotating pin 11 be provided with can with the engaging piece 111 of luer engages with, when dead bolt driven wheel 5 rotates, just can drive with its ingear anti-rotating pin 11 and do straight-line motion, thereby an end that reaches anti-rotating pin 11 enters in the groove 9 or the purpose of coming out from groove 9; Anti-rotating pin 11 should be provided with and be installed in teeth groove 17 places, can block half after anti-rotating pin 11 enters groove 9 or whole erection teeth groove 17, guarantees that tamper spline shift fork 10 can't take out from teeth groove 17 is installed.
Between dead bolt frame 7 and hub spindle core 4, be provided with dust-proof seal ring 14.Outside at the key hole 15 of lock core 2 is provided with watertight cover 16.
In the above-described embodiments, according to the actual conditions of motor bike, also can replace brake cap with the speed meter gear cap.The quantity of dead bolt and shape can be decided as the case may be, but are advisable with 3-4.
In the above-described embodiments, kinematic mechanism also can be selected other version for use, so long as can and the structure of anti-rotating pin motion all can with the key interlock, for example can be that spiral, the projective table type that is complementary with described tongue driving device or the wheel word of screw-type also can be spring loaded, spring-piece type or the plectrum formula flip flop equipments that is complementary with described key bit, can also be external force driving driving device etc.
Principle of work of the present utility model is: during the key turns that is complementary with lock core 2 (structure of lock core is general known configurations), drive is rotated by the taper lock gear 3 of key control, taper lock gear 3 drives the dead bolt driven wheel interactive with it 5 again and rotates, make with dead bolt driven wheel 5 on the dead bolt 6 of cycloid 51 tablings do the motion of stretching or contracting, when extending into, dead bolt 6 is fixed on hub of motorcycle axle core 4 when locking in the dead bolt hole of orifice ring 8, the nave boss of motor bike is locked, when dead bolt 6 contracted in dead bolt hole, the motor bike nave boss was opened; In addition, when taper lock gear 3 drives the dead bolt driven wheel interactive with it 5 rotations again, dead bolt driven wheel 5 drives anti-rotating pin 11 by kinematic mechanism and moves, and anti-rotating pin 11 is inserted in the groove 9, makes tamper spline shift fork 10 can not rotate above 360 ° and also can't take out.
So just make wheel and lock to take off together, motor bike just can not go adrift yet; And for the machine made drg of pull bar, even pull bar is taken off, because the existence of tamper spline shift fork and anti-rotating pin, drg can not rotate around axletree with wheel and surpass 360 °, and motor bike also just can not be pushed away; In a word, use of the present utility model has increased the motorcycle anti-theft safety greatly.
As shown in Figure 3 and Figure 4, it provides another kind of embodiment of the present utility model, its difference is: groove 9 ' is two arc-shaped grooves, it forms by difform part spelling, and the rotatable angle of the shift fork of tamper spline like this 10 in groove just greatly reduces, when anti-rotating pin 11 pins, for the machine made drg of pull bar, even pull bar is taken off, drg will greatly reduce than 360 ° around the angle that axletree rotates with wheel, and will be firm more, stable.
