Description

Bicycle anti-theft alarm lock

The utility model relates to a kind of anti-theft alarm lock, particularly a kind of bicycle anti-theft alarm lock.

Existing vehicle anti-theft alarming lock, alarm still is in unnecessary guard state when vehicle is put into the safety zone, and its sounding component easily goes to pot, and antitheft coefficient is not high.

The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of in not power consumption of guard state, easy to install, the bicycle anti-theft alarm lock that the car owner can monitor vehicle safety.

The purpose of this utility model is achieved in that adopting special mechanical lock and electronic technology to organically combine constitutes, and it is made of lock gall 1, lock shaft 3, lock housing 10 etc., it is characterized in that described lock gall 1 one ends are connected with slide block 2, and the other end and battery door are joined; Boss 12 is arranged at the bottom of slide block 2, and boss 12 embeds in the groove of opening on the lock shaft 3 13, and the top of slide block 2 and contactor push rod 4 join, and push rod 4 links to each other with contactor 8, and the other end of push rod 4 passes the hole 14 of lock housing 10 and stretches out outside the lock housing 10; Electronic circuit box 6 is located in the lock housing 10, and the sensor 5 that shakes is connected with electronic circuit box 6, and loudspeaker 7 also join with electronic circuit box 6; Described lock gall 1 is provided with spring 15 and raised line 16, and raised line 16 inserts in the slide block 2; Also be provided with battery 9 in the described lock housing 10, battery door 11 is set on the lock housing 10.

Principle of the present utility model is: after lock is locked, and the contactor that closes, alarming lock enters on the alert.When body external force bump, prize, when hitting, the sensor that shakes promptly charges to electric capacity by gauge tap, vibration is become acoustic pulse amplify through electron gain and give the loudspeaker pronunciation and reach the warning purpose.

The drawing of accompanying drawing is described as follows:

Fig. 1 is a structural representation of the present utility model,

Fig. 2 is a partial structurtes schematic diagram of the present utility model,

Fig. 3 is embodiment 1 schematic diagram of the present utility model,

Fig. 4 is embodiment 2 schematic diagrames of the present utility model

Fig. 5 is circuit theory diagrams of the present utility model.

Below in conjunction with accompanying drawing or embodiment the utility model is described in further detail; Lock gall 1, slide block 2, lock shaft 3, contactor push rod 4, the sensor 5 that shakes, electronic circuit box 6, loudspeaker 7, contactor 8, battery 9, lock housing 10, battery door 11, boss 12, groove 13, hole 14, spring 15, raised line 16.Shown in Fig. 1～3, a kind of bicycle anti-theft alarm lock, it is made of lock gall 1, lock shaft 3, lock housing 10 etc., it is characterized in that described lock gall 1 one ends are connected with loose piece 2, and the other end and battery door are joined; Boss 12 is arranged at the bottom of loose piece 2, and boss 12 embeds in the groove of opening on the lock shaft 3 13, and the top of slide block 2 and contactor push rod 4 join, and push rod 4 links to each other with contactor 8, and the other end of push rod 4 passes the hole 14 of lock housing 10 and stretches out outside the lock housing 10; Electronic circuit box 6 is put in the lock housing 10, and the sensor 5 that shakes is connected with electronic circuit box 6, and loudspeaker 7 also join with electronic circuit box 6; Described lock gall 1 is provided with spring 15 and raised line 16, and raised line 16 inserts in the slide block 2; Also be provided with battery 9 in the described lock housing 10, battery door 11 is set on the lock housing 10.

As shown in Figure 4, when the spring tension that overcomes lock shaft 3 with external force, with lock shaft when the lock shaft guide pin bushing moves to slide block 2 convex clip sheets and aims at the lock shaft groove, because of the lock gall spring force return of lock gall 1, the lock gall raised line drives slide block convex clip sheet and enters the lock shaft groove, and blocking lock shaft can not return and bicycle is pinned.Slide block 2 leaves contactor push rod 4 simultaneously, can depress the connection circuit protruding the outer contactor push rod of lock housing.Circuit is in the state of alert.Can will vibrate pulse frequently and give loudspeaker 7 pronunciations by the sensor 5 that shakes to the electric capacity charging as bumping, prize, hit promptly, reach the warning purpose through electron gain amplification 6.Looked the intensity time of fire alarming that bumps, prize, hit 2 seconds to 45 seconds.Vibration pronunciation warning once more once more.

As shown in Figure 5, when rotating a lock gall 1 with spoon, the lock gall raised line drives that slide block 2 is up, and slide block convex clip sheet leaves lock shaft 3 grooves, and lock shaft is done because of the lock shaft spring draws to reset along the lock shaft guide pin bushing and unblanked.When simultaneously slide block 2 is up contactor push rod 4 is pushed to outside the up protrusion lock housing, circuit disconnect switch, circuit are not in the state of alert can not send warning.

As want burglar alarm, and can depress the contactor push rod of protrusion outside lock housing, contactor closes.Electronic circuit promptly stands alert.Bump, prize, hit bicycle if any robber person and promptly can charge to electric capacity, will vibrate acoustic pulse and amplify through electron gain and give the loudspeaker pronunciation and reach the warning purpose by the sensor that shakes.Looked oscillation intensity, warning tone period 2 seconds to 45 seconds.Vibration pronunciation warning once more once more.Mute not electric consumption.Shake sensor and electronic circuit all is enclosed in the plastic casing, but moisture proof.Do not influence the warning effect at moist rainwater weather.

The utility model has following advantage compared to existing technology: simple in structure, reasonable in design, Stable and reliable for performance, use lightly easyly, report to the police accurately. Not power consumption on the alert source, battery Door has the lock gall hook lock to close fastening will change battery with just opening the battery door dress after the key unlatching.
