Background technology

Because the continuous generation of larceny case, the people's property can not get guarantee, government has also taked the relevant precautionary measures with public security department, but to there not being effective way on the problem of avoiding theft.Whether there are following defective in existing electronic lock and mechanical lock: (1) electronic lock Contact Sensor: steal, touching promptly and ringing, send the noise of chirping, wasted power supply, paralysis people's vigilance; (2) the mechanical lock iron bar runs through formula: the robber commits theft, and cuts off lock bridge earlier or damages lock core, and bass does not have sound, is easy to go smoothly, and the thief is advanced unopposed; (3) " steal the fearness police, steal fearness sound ", the person of thieving has a guilty conscience, and as sending cry sound at this moment, will play deterrent effect to committing theft, but the equal no this item function of existing lock class; (4) the built-in circuit of electronic lock, inject sulfuric acid after, destroyed easily, it is ineffective to report to the police; (5) automobile burglar, warehouse security personnel do not have the acoustic control lamp electro-optical device, and inconvenient long distance is reported to the police.

Summary of the invention

Technical problem to be solved in the utility model is multi-functional language alarm safety anti-theft lock.

The technical scheme that the technical problems to be solved in the utility model adopted is: lock bridge, backguy, housing, lock core cover, key, lock core, battery, pronunciation loudspeaker, speech amplifier, turn round sub-switch, blind rivet, spring, conducting strip and link together.

Pronounce in the described technical scheme loudspeaker, speech amplifier, turn round sub-switch, conducting strip, battery interconnects and parts such as lock core, backguy, spring, blind rivet are fixed within the iron-clad, become a complete iron-clad independence closed system, and waterproof, fire prevention, shockproof, antimagnetic, anticorrosion five-term measure have been taked, all there are sound hole, fastening devices in front and back, each contact control power supply, the contact is connected power supply automatically during destruction, sounds language alarm.

Technical characterictic of the present utility model is: conducting strip with turn round sub-switch and link to each other, lock core links to each other with conducting strip, when the lock core left rotation and right rotation surpasses 180 when spending, connects power supply automatically with conducting strip.String has backguy in the lock bridge cavity, and backguy one end is fixed on the blind rivet, and blind rivet links to each other with spring, and when lock bridge was cut off destruction, backguy touched spring and turns round sub-switch with regard to collision, starts power supply, gives the alarm.Its critical component, the sealing of circuit plate are arranged in the high-pressure plastic shell of antiseptic property, needn't worry to inject the damage of sulfuric acid; To the theftproof lock of the large-scale vehicle of automobile, its electrophonic musical circuit is connected the peripheral hardware tweeter in addition, control circuit, stop, be communicated with warning system; Warehouse theftproof lock pronunciation circuit connects the peripheral hardware tweeter, illuminates gate light, displaying alarm.

Compared with prior art, technique effect of the present utility model is: all thieves cut off lock bridge, destroy lock core, and this locks self-opening power supply, and send strong shriek, language alarm: " well! Scrounge, stop thief soon! " and ceaselessly recursive call loudly, in time warning arouses attention, and safety is guaranteed in the shock crime.Really play anti-theft effect, maintain social stability, the protection property is not suffered a loss.
