Fig. 1 be the utility model outdoors lock core with cut-away view that to be provided with three groups of pellets shot from a slingshot be embodiment;
Fig. 2 is the structural representation of the utility model break-in joint;
Fig. 3 is circuit theory diagrams of the present utility model;
The utility model is described in further detail below in conjunction with accompanying drawing:
Machine one fax sense probe 8 is housed in the lock core outdoors 4 on the lock body 1, and the upside of lock body 1 is provided with anti-broken lock break-in joint 10, also is provided with the anti-break-in joint 11 of forcing open the door on the alarm 12, and is in parallel with anti-broken lock break-in plug 10 through lead.Anti-broken lock break-in joint 10 and the anti-break-in joint 11 of forcing open the door are formed by plug and socket, in case broken lock plug, socket are example: plug is formed by inner core 14 and outer core 16 suits, between inner core 14 and the outer core 16 clearance for insulation 17 is arranged, inner core 14 passes outer core 16, and outer core 16 two ends are connected and fixed on inner core 14 by collets 15, collets 18 respectively.Corresponding to plug, socket 20 is the isolator with a conductive jack 19, and a side is fixed with the shell fragment 22 that is connected with the inner core terminals in the socket 20, and its respective side is provided with the outer core terminals 21 that combine as a whole with jack 19.When plug did not insert socket 20, shell fragment 22 was connected with outer core terminals 21, when plug insertion socket 20, shell fragment 22 separates with outer core terminals 21, be connected with shell fragment 22 by inner core 14,16 in outer core is connected with outer core terminals 21, thereby plays the switch control action.When the robber adopts brokenly the lock form and when going into the bump lock, lock body will be moved, plug comes off in socket 20, and promptly anti-broken lock control K switch 2 closures trigger alarm 12 and report to the police.In like manner, force open the door form and when going into to force open the door when the robber adopts, as long as door separates certain distance with doorframe, as greater than 5CM the time, plug will come off in socket, and the promptly anti-gauge tap K3 closure of forcing open the door triggers alarm 20 and reports to the police.
Alarm 12 is provided with delay circuit, control module and alarm module, and wherein control module is by phase inverter F 1-2, resistance R 3, triode T and relay J 1-3Form, and phase inverter F 12 output termination phase inverter F 21 input, delay circuit adopts by resistance R 1, R 2And capacitor C 1The RC circuit of forming connects power supply E positive pole by probe gauge tap K control, and the output of its RC circuit is successively through phase inverter F 1, F 21 input and resistance R 3Connect the base stage of triode T, the grounded emitter of triode T, colelctor electrode respectively through and the relay J of second tube sheet D arranged 1, J 2Connect power supply E positive pole, and relay J 1Normal open switch J 1K 1Meet the anodal and probe gauge tap K of power supply E respectively, its normally closed switch J 1K 2Connect the other end of probe gauge tap K, relay J 1Normal open switch J 1K 2, normally closed switch J 1K 1The other end meet phase inverter F respectively after linking to each other 1, F 23 inputs, phase inverter F 1, F 24 input end groundings, relay J 2Normally closed switch J 2K 1One end is through relay J 3Ground connection, the other end are respectively through anti-broken lock control K switch 2, the anti-gauge tap K that forces open the door 3And relay J 2, J 3Normal open switch J 2K 2, J 3K 2Connect power supply E positive pole and meet loudspeaker S through alarm module P.
With one group of machine-fax sense probe is example: the probe 8 in the lock core 3 is provided with base 6 outdoors, base 6 is pressed on the holder 5 and is carrying stage clip 7 on the back, probe 8 passes stage clip 7 centers and passes lock core 3, by pellet shot from a slingshot 4 concavo-convex according to key bit in the teeth groove 2, control the conducting of probes 8 and relaying shell fragment 9 successively through holder 5, base 6, constitute probe gauge tap K, control triggers alarm 12 and reports to the police.The key that uses when identification not to the time, probe gauge tap K closure is delayed time to trigger in about 3 seconds through the RC delay circuit and is reported to the police, at this moment, capacitor C 13Through resistance R 2Control module was discharged about 30 seconds~2 minutes, cut off warning circuit voluntarily, wait for identification next time.
Power supply E positive pole is by bell button K 4Control doorbell M outputs signal to loudspeaker S, and simultaneously, power supply E positive pole also is serially connected with normally closed button KF, when need stop to report to the police, only needs just can interrupt by normally closed button KF the power supply of alarm module P, thereby interrupts continuing to report to the police.
For easy for installation, also can correspondence be provided with the break-in joint on lock body 1 and the alarm 12, realize being connected of relaying shell fragment 9 and alarm 12 on the lock body 1 by the break-in joint.
