Bicycle theft, it is the thing of the headache of car owner, the present bicycle lock that uses, generally form by lock shaft, lock core and lock housing three parts, the present theftproof lock that occurs, adopting maximum ways is exactly that lock shaft overstriking or lock shaft are formed by many, prizes and steals or cut that to steal the lock effect be not too big but these ways tackle the thief, and bicycle theft still takes place often.The report that anti-theft alarm lock was also once arranged on the newspapers and periodicals, but all owing to its warning system adopts attachment device does not easily destroyedly have an antitheft effect, the cost height, and poor reliability etc. are former thereby be not widely used.

The purpose of this utility model is to overcome the shortcoming of prior art, a kind of bicycle anti-theft alarm lock is provided, it is simple in structure, and lock body does not have attachment device outward, and is with low cost, the reliability height, misoperation can not take place, reach as owner and lock car, driving, with car freely, do not have heteromophism, and when the thief prized and stole or cut the robber to this lock, warning device promptly was exposed to the thief in public.

The purpose of this utility model is achieved through the following technical solutions: bicycle anti-theft alarm lock, by lock shaft, lock core and lock housing three parts are formed, lock shaft is provided with breach, during the lock car, the pintle hook lock of lock core is stuck in the breach A, lock core is installed in the closed cavity of lock housing one side, the voice integrated package also is installed in the cavity, loudspeaker, power supply alarming is checked gauge tap, power supply, alarm switch also is installed in the opposite side of lock housing, the front end of lock shaft is equipped with the alarm switch chip, power supply alarming is checked gauge tap, alarm switch and power supply series connection, be connected on the integrated package then, loudspeaker are connected between integrated package "+" pin and the output pin, three preformed holes are arranged on the voice integrated package, be used to install triode BG, voice integrated package one side also is connected with a resistance R, on the lock shaft under the breach A 1～2cm place establish a breach B again, check gauge tap 4 configurations with power supply alarming.

The alarm switch chip is an insulating trip.

Power supply alarming checks that gauge tap links to each other with lock core, its action is consistent with the switch of lock, alarm switch is opposite with the switch of lock, have only as the car owner and check whether power-supply battery has electricity and warning system whether normal, when being about to lock unlatching back lock shaft stroke 1～2cm, lock car once more, the lock core pintle hook lock is stuck in the breach B of lock shaft, power supply alarming is checked switch connection, and this moment, power supply alarming checked that gauge tap and alarm switch all are in closed condition.

Alarm switch is spring contact device or touches the formula switch, and alarm switch and alarm switch chip are complementary, and when lock cut out, the alarm switch chip card was between two spring leafs of alarm switch.

The utility model will be further described below in conjunction with accompanying drawing.

Fig. 1 is the structure chart of bicycle anti-theft alarm lock

Fig. 2 is the circuit diagram of bicycle anti-theft alarm lock

As shown in Figure 1, bicycle anti-theft alarm lock comprises lock shaft 1, lock core 6 and lock housing 7, lock shaft 1 is provided with two breach A, B, at a distance of 1～2cm, during the lock car, the pintle hook lock of lock core is stuck in the breach A, and lock housing 7 one sides have a cavity, lock core 6 is positioned at cavity, voice integrated package 2 also is housed in the cavity, loudspeaker 3, power supply alarming is checked gauge tap 4 and power supply 5, alarm switch 8 is positioned at the lock housing opposite side, alarm switch chip 9 is positioned at the front end of lock shaft 1, and the alarm switch chip is an insulating trip, and alarm switch is spring contact device or touches switch, be complementary with alarm switch chip 9, when lock cut out, when promptly pintle hook lock was stuck in the breach A, the alarm switch chip card was between two contacts of alarm switch.Power supply alarming checks that gauge tap 4 links to each other with lock core 6, and its action is consistent with the switch of lock, and when unblanking, power supply alarming checks that gauge tap disconnects; When the lock car, power supply alarming is checked the gauge tap closure.Alarm switch 8 is opposite with the switch of lock, and behind the lock car, alarm switch disconnects; When unblanking, Alerts Off is so that owner uses car, have only as the car owner and check whether power-supply battery has electricity and warning system whether normal, the pintle hook lock that is about to lock unlatching rear lock core ejects in breach A, during lock shaft stroke 1～2cm, lock car once more, this moment, pintle hook lock was stuck in the breach B of lock shaft, because lock is in closed condition, power supply alarming checks that gauge tap also is in closure state, since the lock shaft stroke 1-2cm, the alarm switch contact has left the contact of alarm switch, makes alarm switch also be in closure state.
