The specific embodiment

The specific embodiment of the present utility model is described with reference to the accompanying drawings.

With reference to figure 1, Fig. 2, Fig. 3, the utility model anti-theft lock for motorcycle comprises lock body 7, lock pin 5 and lock pin handle 6, under overall structure, lock pin 5 one ends and lock pin handle 6 are affixed, but lock pin 5 other ends are connected with the locking of lock body 7 plugs ground, the cross section of lock body 7, lock pin handle 6 is wider than the cross section of lock pin 5, and certainly, the cross section of lock body 7, lock pin handle 6 also should be wider than by lock assembly (as the circular hole on the motorcycle front-wheel brake disc).

Can find out also that from figure the lock body 7 of the utility model anti-theft lock for motorcycle is made up of lock tube 1 and lock core 2, lock core shaft 3, lock core 2, lock core shaft 3 are sleeved in the lock tube 1 successively.

For lock core 2 is fastened in the lock tube 1, the tube wall of lock tube 1 is provided with pin hole, uses dowel fixes between lock core 2 and the lock tube 1.Lock core shaft 3 is 1 rotatable the setting in lock tube, and the opposite end with keyhole 21 on the lock core 2 is provided with lock core tongue 22, and an end is useful on the groove that blocks lock core tongue 22 in the lock core shaft 3, during connection, lock core tongue 22 inserted groove; The other end of lock core shaft 3 has lock pin 5 jacks, and its shape, size can match with lock pin 5 external surfaces; For lock pin 5 is stuck in the lock pin jack, the tube wall of lock core shaft 3 is provided with the steel ball hole, the outer wall aperture in this steel ball hole is greater than the diameter of steel ball 4, its inwall aperture is slightly less than the diameter of steel ball 4, when steel ball 4 is put into the inside, the steel ball hole can just all be contained steel ball 4 and outwards do not protruded, with the lock core shaft 3 that guarantees to be equipped with steel ball in 1 li rotation of lock tube freely; But steel ball 4 protrudes a part from the inside to the lock pin jack, and this projection just in time is used for blocking in the steel ball draw-in groove 51 that stretches on the lock pin jack lock pin 5.Correspondingly, be provided with hole clipping 11 with steel ball hole same cross-sectional on the lock tube 1, these hole clipping 11 apertures are more smaller than steel ball, when rotation direction hole clipping 11 positions, steel ball hole make two holes superimposed, steel ball 4 can move to hole clipping 11 from the steel ball hole by the effect of lock pin 5 external force, and this kind situation lost efficacy to the screens of lock pin 5; In order to make theftproof lock more firm with combining of lock pin 5 under user mode, the steel ball hole is one or more, and the hole clipping 11 of respective cross-section is made as one or more matchingly on the lock tube 1.

With reference to figure 3, Fig. 5, the two ends cross-sectional sizes of lock pin 5 differs, wherein there is an end of steel ball draw-in groove 51 thinner, the other end of lock pin 5 has a diameter increase portion 52, and these diameter increase portion 52 peripheries are provided with external screw thread, and lock pin handle 6 is a tubular metal, its inner tubal wall comprises leading portion, stage casing and the back segment that internal diameter increases successively successively, this stage casing is provided with internal thread, and lock pin 5 penetrates from lock pin handle 6 inner tubal wall back segments, and its diameter increase portion 52 is spirally connected with lock pin handle 6 inner tubal wall stage casings.Simultaneously, can also put a lid 8 at the end of lock pin handle 6, after lock pin 5 screws, lid 8 screwed cover at lock pin 5 ends of thread, can reinforce the connection of lock pin 5, it is preferably identical with lock tube 1 to prevent that rainwater from entering shape, the size of the screw thread of lock pin 5 corrosion lock pin handle 6, so that unify processing and manufacturing.Lock tube 1 can also be made as ball handle shape with an end of lock pin handle 6, be convenient to application of force rotation, and appearance effect is better.

Lock pin 5 can also adopt another kind of mode with being connected of lock pin handle 6.As Fig. 4, lock pin handle 6 one ends are provided with fitting recess, and the outer imperial palace of the diameter of this fitting recess is little stepped; Match with lock pin handle 6, lock pin 5 has a diameter increase portion 52 and becomes external screw thread in its Surface Machining, correspondingly at lock pin handle 6 fitting recess smaller parts internal thread is set, and this diameter increase portion 52 is spirally connected by screw thread with this fitting recess smaller part; The big portion of this fitting recess is combined with a pressure ring 9, and this pressure ring 9 is fixedlyed connected by pin 10 with the fitting recess sidewall.More firm for lock pin 5 is connected with lock pin handle 6, a plurality of pin holes can be set on the inner hole wall of lock pin handle 6, and on lock pin 5, establish cotter slot accordingly.

Above-mentioned lock pin 5 and lock pin handle 6 can be regulated the length that lock pin 5 exposes to lock pin handle 6 parts by being threaded, thereby applicable to different vehicles.Certainly, lock pin 5 and lock pin handle 6 can also be one-body molded in steel mould, and this connection is also very firm.

In order to prevent violence damage lock core 2, turning collar in the middle of the lock core 2 is with respect to lock core shell and lock core tongue 22 rotatable settings, can only could drive the rotation of transmission mechanism control lock core tongue 22 and lock core shaft 3 by key, when exerting oneself picking lock core 2, can't find fixing origin of force like this, strengthen the theftproof performance of lockset greatly.For lock core 2 is fastened in the lock tube 1, the tube wall of lock tube 1 is provided with pin hole, uses dowel fixes between lock core 2 and the lock tube 1.

Above-mentioned only is the specific embodiment of the present utility model, but design concept of the present utility model is not limited thereto, and allly utilizes this design that the utility model is carried out the change of unsubstantiality, all should belong to the behavior of invading the utility model protection domain.
