Abstract
The utility model discloses a theft-proof alarm lock for bicycles or motorcycles. On the base of the locking of the head of a lock bolt, a set of alarm device is added. After the lock bolt is inserted into a casing and locked, a mains switch is closed, and an alarm switch is closed by the lock bolt and screws simultaneously. Once the lock bolt or fastening screws are prized, the alarm switch is cut off, an alarm circuit is triggered and switched on, and a loudspeaker can send out continuous alarm sound. So the quiet stealing condition of a thief is destroyed, the thief is scared, and an owner is informed by the sound.
Description
The utility model relates to a kind of bicycle motorcycle lock, particularly a kind ofly can prized the bicycle motorcycle anti-theft alarm lock of the sound that gives the alarm simultaneously.
At present, the lock that uses on bicycle, the motorcycle is of a great variety, and form is different, and the locking of locking bolt middle part is arranged, and the locking of locking bolt head is also arranged.Though many advantages are arranged, but still have weak point, promptly have only a lock function with regard to lock itself, the thief can destroy this lock function in relatively more stable environment.If on the basis of lock function, add a function of destroying the stable environment of thief, make the thief panic, can prevent further effectively that bicycle, motorcycle are stolen.
The purpose of this utility model will provide a kind of exactly and not only have lock function, and has the bicycle motorcycle anti-theft alarm lock of warning function.
The bicycle motorcycle anti-theft alarm lock is achieved in that the utility model adopts plug-type spoon of control electronic structure of locking bolt.Its locking bolt tubulose that takes the shape of the letter U, after inserting housing, its bayonet socket keeps off connecing with dead bolt and cooperates, and is lock-out state.Housing is fixed on by Ka Gai and deck on the vehicle frame of bicycle or motorcycle, and not the time spent, locking bolt inserts in the idle hole, when locking, locking bolt is taken off in the insertion lock hole.
In enclosure interior warning device is housed.Warning device is power circuit, abnormal detection circuit, monostable circuit, warning circuit, power amplifier composition.Under the state of alert, promptly under the lock-out state, by dead bolt with power switch K
1Closed.Simultaneously, the contact roof pressure under the trip bolt of the contact by the locking bolt head and Ka Gai and deck both sides contacts, and makes K switch
2Closure, report to the police this moment and the power amplifier power supply all is in off-state, and operating current is minimum; Under alarm condition, promptly the thief touches locking bolt or dismounting trip bolt, all can make K switch
2Disconnect, this moment abnormal detection circuit, the triode T in the monostable circuit
1, T
2Saturated, the circuit triggers conducting is reported to the police and the power amplifier power supply is switched on, and warning device then can sound the alarm incessantly by loudspeaker.Both made this moment of roof pressure locking bolt or tightly tighten screw again again, made K
2Closure is because of triode T
2Still be in saturation state, the power supply of warning and power amplifier still can be in by T
2On-state, so chimes of doom can not be interrupted.
The utility model is by having installed a cover warning device additional in housing, its lock body itself then adopts the pick-proof structure of locking bolt head locking, make bicycle, motorcycle anti-theft alarming lock have double-deck function, promptly have locking and warning function, it can destroy thief's stable environment effectively, makes it panic.If owner do not walk out effective audition scope as yet, hear chimes of doom after, can return rapidly.
