Abstract
The utility model discloses an electronic warning anti-theft lock for the theft protection of a bicycle, mainly composed of a micromotion sensor, an alarm condition switch, an alarm cancelling switch, a steel rope, a lock core, a lock head, an alarm circuit and a cut-off circuit. The steel rope and the micromotion sensor are communicated with the cut-off circuit through the alarm condition switch. Alarm signals are conveyed to the alarm circuit through the cut-off circuit. Under the alarm ready condition, the sound alarm can be caused by that the steel rope is sheared or the bicycle is transported. The electronic warning anti-theft lock of the bicycle can not damage or produce the false alarm through wetting or showering by rain water.
Description
The utility model relates to a kind of lockset, particularly a kind of alarm anti-theft lock that is used for bicycle theft-prevention.
Chinese patent CN92226841 discloses a kind of anti-theft lock for bicycle, it is by with steel cable that bicycle lock is antitheft to carry out on fixture, and, in steel cable, penetrate lead and be used for breaking alarming, this theftproof lock, in case not having fixture can lock, bicycle just is difficult to play antitheft effect, and, in steel cable, penetrate lead, very easily in the welding or the process of punching press tapered end, destroy or scrapped, in addition by the pinch off lead, rainwater is also very easy to be entered in the lock and internal circuit is made moist, and influences warning function.
The purpose of this utility model is to provide a kind of steel cable or locking states cut off to remove that car is reported to the police and bicycle electronic warning and anti-theft lock moistureproof, waterproof for the deficiency that solves above-mentioned technology.
In order to achieve the above object, the designed bicycle electronic warning and anti-theft of the utility model is locked it and is comprised housing, lock core, steel cable, tapered end, lock casket and electronic warning unit, wherein the electronic warning unit mainly is made up of fine motion sensor, alarm condition switch, disappear alert switch, power switch, power supply, cut-off circuit and warning circuit, steel cable and fine motion sensor are connected with cut-off circuit by the alarm condition switch, alarm signal transfers to warning circuit by cut-off circuit, the alert switch series that disappears is connected between power supply and the earth point, and housing adopts metal stretching to make.The emergent for convenience police that disappears is provided with the alert hole that disappears on housing, the alert switch that disappears is located in the alert hole that disappears.In addition, in order to reach moistureproof, waterproof purpose, electronic component all is encapsulated in the epoxy resin in the lock.
This bicycle electronic warning and anti-theft lockset has disconnected newspaper and touches the dual warning function of newspaper, when bicycle parking in safety relatively or have that the people keeps an eye on local time, can use monolock to report to the police, promptly as long as steel cable is passed wheel, with transfering to key to get final product in the tapered end insertion lock casket, there is the people will report to the police immediately as steel cable is managed to break.As be parked in not really place of safety, except with on the steel rope lock, stir the alarm condition switch again, make the fine motion sensor be in SBR, move bicycle or break steel cable and all will report to the police this moment, inserts power cutoff or help the emergent police that disappears by the alert hole that disappears up to owner's key.After in the steel cable tapered end inserts the lock casket, pinning, as unblanking, as long as a key is toward counterclockwise changeing one grade, be power cutoff, rotate certain position more backward and can transfer to tapered end, during driving, steel cable inserts tapered end in the lock casket forward, and power cutoff gets final product safe driving.
The bicycle alarm anti-theft lock that the utility model obtained, both prevented that auto theft person from cutting off the steel cable auto theft, prevented to connect back frame again and walked, and also can not damage this lock or produce false alarm because of making moist or drenching into rainwater, it has certain realistic meaning to preventing bicycle theft.
Fig. 1 is a bicycle alarm anti-theft lock front schematic view.
Fig. 2 is a bicycle alarm anti-theft lock schematic rear view.
Fig. 3 is an electronic warning element circuit schematic diagram.
In conjunction with the accompanying drawings the utility model is further described below by embodiment.
As shown in Figure 1 and Figure 2, the described bicycle electronic warning and anti-theft lock of present embodiment mainly comprises housing 1, lock core 2, steel cable 3, tapered end 4, lock casket 5 and electronic warning unit 6, as shown in Figure 3, wherein electronic warning unit 6 mainly is made up of fine motion sensor 7, alarm condition switch 8, disappear alert switch 9, power switch 10, power supply 11, cut-off circuit 12 and warning circuit 13.Steel cable 3 and fine motion sensor 7 are connected with cut-off circuit 12 by alarm condition switch 8, and alarm signal transfers to warning circuit 13 by cut-off circuit 12, and wherein, cut-off circuit 12 is mainly by transistor BG
1, BG
2And resistor R

5With capacitor C
1Form, steel cable 3 one ends are communicated with capacitor C, and the other end is connected with a end of fine motion sensor and alarm condition switch 8.The c end of alarm condition switch 8 links to each other with the other end of fine motion sensor 7, the b end of alarm condition switch 8 links to each other with two inputs of warning circuit 13 with the d end, the alert switch 9 that disappears is serially connected between power supply 11 and the earth point, and the alert switch 9 that disappears is located in the alert hole of being offered on the housing 1 14 that disappears, the bicycle electronic warning and anti-theft lock that obtains thus, when work, as steel cable 3 is disconnected, electric current is from R
1Flow through C
1Charging, transistor BG
1, BG
2Conducting work, triggering warning circuit 13 reports to the police, fine motion sensor 7 is by silver-plated bowl-type sheet metal and the combination of silver-plated metal ball, it is good to make it to have contact, disconnect flexible characteristic, under the normal condition, fine motion sensor 7 is in closure state, and the end of the C by alarm condition switch 9 makes steel cable 3 be in conducting state, and circuit is in by anti-theft state.After producing vibrations, fine motion sensor 7 disconnects, and makes the cut-off circuit conducting and produces warning.Alarm condition switch 9 is selected third gear switch for use, middle bay b triggers and reports to the police, also promptly has direct triggering charging conducting warning effect at once, at this, newspaper is reported or is touched in not judgement, all can report to the police for a long time after the conducting, have only key power cutoff switch 10 can stop to report to the police, or push the police that disappears that meets an urgent need in the alert hole 14 that disappears with little steel ball, this mainly for owner not the time be not intended to bump or toggle switch and long-time waste power supply three usefulness of reporting to the police, when alarm condition switch 8 pushed a end position, the alert hole 14 that disappears just was plugged, the police that can not disappear walks in case connect the car back of the body together with lock.
The resulting bicycle electronic warning and anti-theft lock of the utility model, housing 1 usefulness metal stretching and molding and and thicker zinc-plated steel cable 3 one ends of multiply securely punching press be linked together, the other end by tapered end 4 firm punching presses together, outsourcing plastic pipe and plastics tapered end handle, after 5 pinnings of tapered end 4 insertion lock caskets, also can't take housing apart with other instrument, with tamper-proof, electric elements in the plastics movement, have good waterproof, shockproof, humidity resistance with epoxy encapsulation in the lock.
