Description

Electronic anti-theft warning lockset

Technical field

The utility model relates to the lock of the mode of closing with keyhole, is specially a kind of electronic anti-theft warning lockset.

Background technology

China is the production and the use big country of lockset, and common mechanical type cylinder lock set still has so far widely and uses because of simplicity and practicality that it had, and still, its defective also is conspicuous.Dead bolt is easily prized, and lockset itself is subject to external force and hits breakage, although adopt a plurality of dead bolts, and has used high-intensity metal material, does not also have basic antitheft effect.After this occurred the electronic anti-theft alarming lock again, the special circuit of arranging in lockset can give the alarm when making lockset destroyed.The cylinder lock that the relative preventive means of this lockset is single is a progress, but this lockset prices are relatively costly, and the two for external electronic anti-theft alarming lock, can make the warning device short circuit alarm lose efficacy, and safety still can not be satisfactory.

Summary of the invention

In order to overcome the defective of prior art, a kind of highly sensitive, lockset that antijamming capability is strong is provided, the utility model discloses a kind of electronic anti-theft warning lockset.

The utility model reaches goal of the invention by following technical solution:

A kind of electronic anti-theft warning lockset, comprise cylinder lock, power supply, time-delay relay, light emitting diode, buzzer and resistance, its structure is: power supply is connected with time-delay relay, light emitting diode, buzzer and resistance successively by lead, the light emitting diode forward is connected in the circuit, this circuit is an incomplete circuit, and inc two ends are respectively at the two ends, lockhole gap at cylinder lock; Power supply also is connected with another buzzer, another light emitting diode successively with resistance, and this light emitting diode forward is connected in the circuit, and this circuit is a closed circuit; Directly be connected with lead between power supply and resistance, this wire arrangements is outside cylinder lock.

Described electronic anti-theft warning lockset, its structure is: the wireless signal transmitter of connecting respectively in closed circuit and the incomplete circuit.

When cylinder lock latches, under normal the use, do not close with circuit in the light emitting diode and the buzzer of connecting not in running order because of opening circuit, light emitting diode of connecting in the closed circuit and buzzer be not because of in running order by the lead short circuit yet.

When unblanking, key inserts lockhole, makes being connected of lockhole and key the place that opens circuit closed, and time-delay relay action this moment can be closed at once in the circuit, when surpassing delay time, closing of circuit, light emitting diode and the buzzer warning that sets.

If the outside destroy lockset is arranged,, there is electric current to pass through in the light emitting diode of short circuit and the buzzer in the closed circuit, light emitting diode and buzzer warning because of the lead that exposes in the closed circuit is disconnected.

In order further to strengthen warning function, can also in circuit, be connected in series wireless signal transmitter, so that in time get in touch with user and security department.

The utlity model has simple in structure, safe and reliable, interference resistance and the strong characteristics of anti-destructive power.

Fig. 1 is a circuit diagram of the present utility model;

Fig. 2 is the warning circuit schematic diagram of the utility model when being subjected to attempting picking lock;

Fig. 3 is the warning circuit schematic diagram of the utility model when being damaged;

Fig. 4 is the circuit diagram of another embodiment of the utility model.

The specific embodiment

Further specify the utility model by the following examples.

Embodiment 1:

As shown in Figure 1, a kind of electronic anti-theft warning lockset, comprise cylinder lock, power supply E, time-delay relay P, light emitting diode D1 and D2, buzzer B1 and B2, resistance R, its structure is: power supply E is connected with resistance R with time-delay relay P, light emitting diode D, buzzer B successively by lead, light emitting diode D forward is connected in the circuit, this circuit is an incomplete circuit, and inc two ends a and b are respectively at the two ends, lockhole gap at cylinder lock; Power supply E also is connected with buzzer B2, light emitting diode D2 successively with resistance R, and light emitting diode D2 forward is connected in the circuit, and this circuit is a closed circuit; Directly be connected with lead between power supply E and resistance R, this wire arrangements is outside cylinder lock.

When illegal instrument was attempted picking lock, lockhole gap a, b were connected by metal, as shown in Figure 2, E → P → D1 → B1 → M1 → R circuit closed, time-delay relay is started working, after surpassing the normal uncaging time that sets, circuit turn-on, light emitting diode D1 and buzzer B1 report to the police.

When external force attempted to destroy lockset, the short circuit lead at first was disconnected, and as shown in Figure 3, light emitting diode D2 and buzzer B2 be no longer by short circuit, E → D2 → B2 → R loop conducting, and light emitting diode D2 and buzzer B2 report to the police.

Embodiment 2:

As shown in Figure 4, the wireless signal transmitter M that in closed circuit and incomplete circuit, connects respectively, like this, when light emitting diode and buzzer work, wireless signal transmitter is also launched wireless signal simultaneously, so that in time get in touch with user and security department.
