The utility model organically is integrated alarm circuit and lock body, and its circuit is simple, and cost is low, and is very easy to use.The utility model do not have any sound during owner's switch lock and reports to the police, in case when the burglar cut, saws, pounds, prizes or move antitheft article, can send the strict chimes of doom of point, in case action stops, the 20-30 that then delays time stops after second reporting to the police automatically, if touch once more, then report to the police once more, anti-theft effect is very desirable.The utility model volume is little, and little power consumption is quick on the draw, and structure design is ingenious, firm, can't dismantle internal wiring, and its good leak tightness has the function of rainproof protection against the tide, has wide application and development prospect.
Fig. 1 is an overall structure schematic diagram of the present utility model;
Fig. 2 is a vibrating sensor schematic diagram of the present utility model;
Fig. 3 is an electrical schematic diagram of the present utility model;
Fig. 4 is an outline drawing of the present utility model.
As Fig. 1, the utility model is to be example to expose the chain type lock, other lock complete class with, dead bolt (3) can be to expose chain type or ring-shaped lock dead bolt, also can built-in ring-shaped lock dead bolt.One end of lock housing body (1) and lock housing cap (10) screw thread spin, corresponding lock housing cap (10) is in lock housing body (1) one end and is provided with battery cavities (11), be used to place battery (12), as warning circuit power supply E, be provided with gauge hole, wiring board chamber (13) and pronunciation chamber (14) in the other end of lock housing body (1), the outer wall in pronunciation chamber (14) has sound hole (15); The position that corresponding lock housing body (1) is gone up jack (9) at the edge of lock housing cap (10) has half garden shape gap, and coincide (as Fig. 4) with jack (9), makes after dead bolt (3) locking lock housing cap (10) and lock housing body (1) fixed to be one.
Operating principle of the present utility model such as Fig. 1-3, when normally shutting, dead bolt (3) inserted in the jack (9) of lock housing body (1), make the lock body closure, and this moment, contact switch K was owing to the insertion of dead bolt (3) is connected, and power supply E begins to pass through resistance R
1To capacitor C
1Charging, this moment is because C
1Two terminal potential deficiencies so though the action that shuts causes the connection of vibrating sensor (4), can not cause effective triggering, can not reported to the police.About 10-15 is about second after shutting, C
1Potential rise is to equating that with the voltage of power supply E this moment, circuit just was on the alert.As long as touch lock housing body (1) in the time afterwards.Will cause the of short duration connection of vibrating sensor (4), promptly the outer end of spring (6) connects two electrode instantaneous short circuit of vibrating sensor (4), so make the capacitor C of second delayer because vibration can swing, and moment is connected the inwall of housing (5)
2Current potential once raise, pass through resistance R then
3To capacitor C
3Charging, after the several seconds (time is by the value decision of resistance capacitance), C
3Potential rise is to timing ic IC
1Triggering level, cause that back level reports to the police.If owner normally unblanks in the above-mentioned several seconds, because dead bolt (3) is thrown off, make that the contact switch K in the jack (9) disconnects, so entire circuit loses power supply, C
1Pass through R
1, R
4, C
2Pass through R
2, C
3Pass through R
3, R
2Discharge, entire circuit is got back to original state, and can not report to the police this moment.If in the above-mentioned several seconds, do not open lock, people's picking lock is perhaps arranged or pound lock, perhaps article or bicycle motorcycle are moved, then vibrating sensor (4) is because the continuous instantaneous short circuit connection of vibration meeting, circuit of the present utility model sends alarm sound immediately by the above-mentioned course of work, finishes the action of automatic warning.If in a single day extraneous vibration stops, then the spring (6) in the vibrating sensor (4) restores balance, and two electrode disconnects, C
2Pass through R
2, C
3Pass through R
3, R
2Discharge makes IC
1The input current potential drop to low level, entire circuit is got back to the state of alert.
