The embodiment that provides below in conjunction with accompanying drawing illustrates structure of the present utility model.

Fig. 1 is the front view of a kind of embodiment of the utility model.Fig. 2 is its left view.Fig. 3 is the front view of the another kind of embodiment of the utility model.Fig. 4 is its left view.

As shown in drawings, a kind of anti-theft lock for motorcycle of the utility model, it has the lock body (1) of increasing, lock core (4) is installed on the lock body, be useful on the installing hole that lock pin (2) is installed on the lock body, the locking bolt (3) of band groove fuses with lock body, is useful on the groove that blocks lock core on the lock pin.

As shown in Figure 3, Figure 4, described lock core (4) is parallel with the installation site of lock pin (2).

As shown in Figure 3, Figure 4, outside described lock pin (2), there is spring (5) to be positioned between the projection outside lock body (1) and the lock pin (2).

During use, lock body is installed on the motorcycle rear axle by the hole on the lock body.In the time of motorcycle need being pinned, promote lock pin, make its head end pass the hole on the sprocket wheel behind the motorcycle, lock pin is stuck in the groove of locking bolt, is rotatably installed in the key on the lock core, dead bolt on the lock core is stuck in the groove on the lock pin, thereby this theftproof lock is locked.After having locked key is extracted.In the time of lock need being opened, key is inserted in the lock core, key breaks away from the groove on dead bolt and the lock pin, lock pin can be extracted out, and lock is opened.Fig. 3, theftproof lock shown in Figure 4, after the groove on dead bolt and the lock pin broke away from, under the effect of spring, lock pin ejected automatically, and lock is opened.

Lock body, locking bolt can form with the cast steel material once-cast, and material is hard.The length of lock body can reach 14cm, wide 5cm, thick 4.5cm, and globality is strong, has firm profile.Because lock pin is included in the lock body, so after this lock was contained on the motorcycle, bolt clipper can not clamp lock pin.What at this moment bolt clipper can be approaching is the bottom of lock body, and because of the narrowest place thickness of this position design also be 35mm, and the maximum of bolt clipper dehisces to be 24mm, so it can't be vised when cutting it with bolt clipper.

Because this lock is locked on the trailing wheel, become obvolvent to surround shape to the chain drive sprocket wheel of motor cycle rear wheel, with the sprocket wheel a little less than the relative thin on the extremely firm lock body protection motorcycle.Make the car stealer can not use bolt clipper, can't use crowbar again.Because if want with crowbar lock to be pried open, what be damaged at first is the back sprocket wheel.If back sprocket wheel is destroyed, motorcycle can't shift fast, thereby can not finish theft.

In addition, because this lock is directly installed on the motorcycle rear axle, therefore has advantage easy to carry.And motorcycle chain is had protective effect, and chain generally can not drop.
