The specific embodiment

For the ease of it will be appreciated by those skilled in the art that utility model is further described in detail below in conjunction with accompanying drawing:

Lock body 3 in the anti-theft lock for motorcycle that present embodiment disclosed is installed on the motorcycle axle sleeve 6, when rotating to extreme position, motorcycle is used to lock motorcycle, motorcycle can only be exercised towards the maximum direction of turning round, can prevent effectively that motorcycle is stolen, tapered end 1 then is installed on is convenient to the panel place that the driver controls, and tapered end 1 and lock body 3 are isolating construction.

Be depicted as the lock head separation structure schematic diagram that this programme discloses as accompanying drawing 1～6.Lock core 2 is installed in tapered end 1, on tapered end 1 and lock core 2, be provided with the lockhole 22 of interspersed key, inductor 21 is installed in lockhole 22, then being provided with on the key and the inductor 21 independent chips 5 that match of pairing, inductor 21 and chip 5 form pairing one by one by encrypting to set, two parts can be bought from the existing market, and cipher mode can set up on their own.Inductor 21 holding wires electrically connect with motor 31 control circuits that are installed in the lock body 1, control the rotating of motor 31 by the instruction of inductor 21 holding wires.Lock core 2 front ends are equipped with between pullover 23, pullover 23 and the lock core 2 that can rotate flexibly by the stop screw axial limiting.Simultaneously, also be provided with the indicator lamp 24 that electrically connects with inductor 21 at lock body 1 front end, after key inserted lockhole 22, if inductor 21 and chip 5 correct paired communication then indicator lamp 24 is bright, indication was opened normally.

Lock body 3 adopts motors 31 to drive, and a bent axle 33 is installed on the output shaft of motor 31, and bent axle 33 is connected with a locking bar 32 power, and locking bar 32 is used for inserting headstock axle sleeve 6 headstock is locked, and therefore, headstock axle sleeve 6 is provided with corresponding through hole 4.Locking bar 32 is provided with a driving hole 321 with bent axle 33 links, driving hole 321 lateral dimensions are consistent with bent axle 33 rotating diameters, and along the axial size of locking bar 32 less than bent axle 33 rotating diameters, can promote locking bar 32 axially-movables when in driving hole 321, rotating with assurance bent axle 33, this syndeton can form self-locking mechanism, guarantees that locking bar 32 can not move automatically.After key inserted in the lockhole 22, chip 5 sent release or locked instruction, and motor 31 driving bent axles 33 are just changeing or reversing, and bent axle 33 drives locking bars 32 retractions or stretches out, and finishes the release and the locked action of 32 pairs of axle sleeves of locking bar.

Motor 31, locking bar 32 front ends all are packaged in the set casing 7, set casing 7 is fixed in the fixed mount 8 by a

connection piece

9,8 of fixed mounts are welded on the headstock axle sleeve 6, and locking bar 32 passes set casing 7, connector 9 and fixed mount 8 and can insert in the headstock axle sleeve headstock is locked.Fix by the screw that welds or pass from bottom to top connector between connector 9 and the set casing 7, connector 9 is close on the fixed mount 8, fixed connecting piece 9 and set casing 7 screw concealed between connector 9 and fixed mount 8, then affixed between connector 9 and the fixed mount 8 by screw from the top down.In order to prevent after the screw that uninstalls between connector 9 and the fixed mount 8, lock body 3 to be disassembled, connector 9 is provided with the fixed strip 91 that extends down in the fixed mount 8, fixed strip 91 is provided with the through hole of interspersed screw, and through hole axle center and locking bar axle center are in the same plane, be fixed with baffle plate 82 at fixed mount 8 near the fixed strip side, be provided with at baffle plate 82 inwalls and be used for fixing screw and the screw-threaded counterbore corresponding with through hole, fixed strip 91 is fixedlyed connected with baffle plate 82 by the screw of from inside to outside installing.When locking bar 32 inserts headstock axle sleeve 6 locking headstocks, locking bar 32 has blocked the fixed screw between fixed strip 91 and the baffle plate 82 and can't dismantle, guaranteed when the headstock lock-out state, can not dismantled release by force, reach the anti-purpose of dismounting, pick-proof by force, and behind locking bar 32 retractions, locking bar 32 is stopping this screw removed position, so that remove and install normally.

The utility model adopts advanced electronic anti-theft encryption chip and cooperates frame for movement cleverly; two-layer antitheft, pick-proof protection is provided; can clearly find out; for the prior mechanical theftproof lock; effect antitheft, pick-proof is more outstanding; no matter from technology itself or technique effect, those skilled in the art all can't realize without creative work.

Above embodiment is the preferable implementation of the utility model, and in addition, all right other implementations of the utility model need to prove that any conspicuous replacement is all within protection domain of the present invention under the prerequisite that does not break away from the present invention's design.
