The purpose of this utility model is achieved in that a kind of alarm anti-theft lock, lock box 2 by steel wire lock 1 constitutes, on the steel wire of lock two insulated wires that are intertwined 3,4 are arranged, electromagnetic switch J, power supply E and alarm 5 are housed in the lock box 2, wherein insulated wire 3 one ends link to each other with power supply E negative pole, and the other end is connected by electromagnetic switch J and power supply E are anodal; One end of insulated wire 4 is open circuit, and the other end is connected with power supply by electromagnetic switch J.
Anti-theft alarm lock provided by the utility model, its insulated wire adopts enamel-covered wire.
Anti-theft alarm lock provided by the utility model, the circuit not power consumption at ordinary times in its lock avoids often changing battery, only just connects circuit and sends chimes of doom when the steel wire of lock is cut off, and plays antitheft effect.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is circuit theory diagrams of the present utility model.
Tapered end of the present utility model, electromagnetic switch J, alarm 5, power supply E are contained in the lock box 2, only reserve keyhole 6, and lock box 2 is installed on the used vehicle, and insulated wire 3 and 4 is wrapped in the steel wire.Owing to not conducting between the insulated wire 3 and 4, electromagnetic switch J is in open circuit dress attitude, i.e. its three contact J at ordinary times
1, J
2And J
3All be in open-circuit condition, this moment consuming cells not, when insulated wire 3,4 is cut off, between two lines during short circuit, electromagnetic switch energising, J
1And J
2Closure, alarm 5 produces chimes of doom, simultaneously J
3Also closed, make electromagnetic switch J continue energising, keep alarm to produce continuous alarm sound.
