Abstract
The utility model relates to the alarm lock technology. The anti-theft alarm lock comprises a casing, a big lock tongue, a small lock tongue, switches K1, K2, a relay J1 connected with the switches K1, K2 in series, a capacitance three-point oscillator, a complementary oscillator, a coupling frequency stabilization circuit connected to the two oscillator, a capacitor C6 connected to an inductor L, an aerial W connected to the capacitor C6, and a loudspeaker connected to the complementary oscillator and the coupling frequency stabilization circuit, wherein, the big and the small lock tongues are arranged in the casing, the switches K1, K2 are connected with the power supply and are arranged on the big and the small lock tongues, the capacitance three-point oscillator and the complementary oscillator are connected with the relay in parallel. When someone pries the door, the anti-theft alarm lock can send out the alarm sound on site, and the alarm signal can be send to the person who carries the receiver at a distance.
Description
The utility model belongs to the technical field of alarming lock.
The alarming lock of using costs an arm and a leg at present, and structure is also very complicated, generally is unsuitable for family and uses, and the warning device as bank uses promptly will have the detection surveillance, and warning system is arranged again.And general insurance cabinet warning system then sounds the alarm when having the people to steal, and can not transmit alarm signal to the distant place.
The purpose of this utility model provides a kind ofly can send alarm sound when having the people to force open the door, can send the anti-theft alarm lock of alarm signal again to remote receiver.
This anti-theft alarm lock comprises shell, cased big dead bolt, and the little dead bolt of cased big dead bolt top also comprises the K switch that is connected on cased big dead bolt below on the power supply of series connection
1With the K switch that is contained on the little dead bolt
2, with K switch
1, K
2Series connection be connected on relay J on the power supply
1, with relay J
1In parallel capacitance connecting three point type oscillator and complementary oscillator are connected on the coupling frequency stabilization circuit on capacitance connecting three point type oscillator and the complementary oscillator, are connected on the capacitor C on the inductance L of capacitance connecting three point type oscillator
6, be connected on capacitor C
6On antenna W, be connected on the loudspeaker on coupling frequency stabilization circuit and the complementary oscillator.
This anti-theft alarm lock has complementary oscillator and capacitance connecting three point type oscillator.Complementary oscillator produces audio oscillator signal when people's picking lock is arranged, drive loudspeaker and send chimes of doom, and capacitance connecting three point type oscillator also produces oscillator signal, launch through antenna, make the user with receiver also can send chimes of doom, therefore when people's picking lock is arranged, can onsite alarming, also can send to the receiver that carries to signal at a distance, send warning.
Accompanying drawing shows embodiment of the present utility model, wherein:
Figure 1 shows that the structural representation of anti-theft alarm lock;
Figure 2 shows that the appearance assumption diagram of anti-theft alarm lock.

After this burglar alarm was locked in and locks the door, big or small dead bolt was connected with dead bolt retaining shell, and simultaneously big dead bolt is K switch
1Closure, and little dead bolt makes K switch
2Being in off-state, when normal door, is to make big dead bolt move K switch earlier
1Disconnect, last little dead bolt moves K
2Closure disconnects again, does not report to the police.When people's picking lock, big dead bolt is motionless in moving by stop device stop is arranged, can only cut off, and when moving little dead bolt, K switch
2Closure, loudspeaker send chimes of doom, if the people stays out and not far nearby place, receiver also sends alarm signal, relay work simultaneously, the circuit power self-locking makes it in K switch
2After the disconnection, still can send alarm signal.
