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.
