Most preferred embodiment of the present utility model now is described, wherein in the accompanying drawing, 1 is lock housing, 2 is tapered end, and 3 is wirerope, and 4 is pintle hook lock, 5 are lock cable card, and 6 are the warning tablet, and 7 is loudspeaker, 8 is microswitch, and 9 is relay, and 10 is mercoid switch, 11 is the wirerope lead, and 12 is the plastic sheath of wirerope and steel cable lead, and 13 are plastic inner shell lock cable fixed mount, 14 is battery case, and 15 is shutter, and 16 are the fear mother of clamp set bolt dress, 17 is the clamp set bolt, 18 is the plastics collar, and 19 for the plastics wirerope fastens bolt, and 20 is the lock plug hole, 21 are lock cable plug, 22 is key, and 23 is installing hole, and 24 is the lock core set bolt, 25 are the lock cable, 26 is the contact-making switch that wirerope and wirerope lead constitute, and 27 is cant beam behind the bicycle, and 28 is the 3V power supply.

Its repeat circuit is 4100 types, and the warning tablet is KD9561, be the commercially available prod.Lock partly is a routine techniques.

The warning bicycle lock comprises lock housing (1), pintle hook lock (4), lock cable (25), lock cable card (5).Plastic inner shell (13) plastic inner shell and lock cable fixed mount one are arranged in the lock housing (1).Plastic inner shell (13) right lower quadrant is tapered end (2), and lock plug hole (20) in the lock housing right side central, (22) are keys, and keyhole is in the lock housing bottom.Mercoid switch (10) is placed on the tapered end and cuts up with a hay cutter in the preformed hole.Microswitch (8) is in the back of tapered end (2), and the contact is over against lock plug hole (20).Lock cable press seal with the lock cable fixed mount (13) of plastic inner shell disjunctor in.Above the lock cable fixed mount is relay (9).Battery case (14) is positioned at tapered end (2) with above the relay (9).Loudspeaker (7) and warning tablet (6) are placed on the back of tapered end (2), and the lock housing dorsal part has venetian blind type sound hole (15).Wirerope (3) is pressed close to be fitted together but mutually insulated with wirerope lead (11), covers wirerope outside both and moulds cover (12).Plastic inner shell (13) is fixed in the lock housing with bolt (24), and lock housing (1) is by bolt (17), and pintle hook lock (4) is fixed on behind the bicycle on the cant beam.Bolt (17) back is furnished with the mother of decoration (16).Lock cable card (5) is fixed on the bicycle cant beam by bolt (19).Cycling do not lock Che Shisuo cable plug (21) snap in the lock cable card (5) opening part fix.

During use,, the warning bicycle lock is fixed on behind the vehicle frame on the cant beam by bolt and pintle hook lock.To lock during the lock car and after cable passes wheel lock plug be inserted the lock plug hole.Lock plug presses microswitch (8) and makes the K7 closure at this moment, is C point and the preceding point of mercoid switch and the wirerope wire connected power positive pole of relay (9).Warning circuit is in alert status.After this be given a shock or tilt mercoid switch K if the car stealer moves car warning bicycle lock ₂Conducting, give relay coil positive pole (B) forward, coil negative pole (A) directly links to each other with power cathode, the relay adhesive, this moment, relay constant close contact D opened circuit, and constant open contact E conducting is thus for warning tablet (6) and loudspeaker (7) provide 3V voltage, because the tablet negative pole directly links to each other with power cathode, circuit turn-on is raised one's voice to ring and is sent alarm sound.Again because relay (E) link to each other to form the relay self-locking between (B), institute and make mercoid switch moment conducting also can make the warning bicycle lock continue to report to the police.In like manner if the car stealer removes to cut the lock cable with pliers, pliers can make wirerope lead and wirerope short circuit conducting, is equivalent to (26) K ₃Conducting, warning bicycle lock continue to report to the police.

If will remove warning, need to open tapered end and will lock the cable plug and from the lock plug hole, extract with key, make microswitch recover off-state, C point cuts off the power supply in the relay, the relay self-locking releasing, relay contact E recovers normally open, at this moment alarm release.

When cycling is not locked car, will lock the cable plug and be fixed in the plastic latch cable card, lock is removed alert status, and the bicycle vibrations tilt all not report to the police.
