Description

Ring-shaped electronic alarm lock

The utility model relates to the soft lock of a kind of annular, specifically a kind of circulating electron alarming lock.

The annular soft lock kind of Xiao Shouing is more in the market, and chain structure is arranged, and wire rope structure etc. is arranged, but existing technology only is the mechanical type ring lock, but just owing to use soft connection, mechanical strength is limited, very easily is cut off destruction, thereby has lost the basic function of lock.

The purpose of this utility model is to provide a kind of circulating electron alarming lock that electronic alarm device is housed in lock body.

To achieve these goals, the utility model adopts following technical scheme: a kind of circulating electron alarming lock, comprise lock body, lock ring and dead bolt, it is characterized in that being equipped with in the lock body electronic alarm device, this installs by power supply, alarm, forms from mat transformer, electronic switch, integrated circuit, transistor and resistance capacitance, alarm with form a parallel circuit from the mat transformer, a termination power positive pole of this circuit, the other end is through meeting transistor G from mat transformer centre tap ₁Colelctor electrode, this transistor emitter ground connection, base stage connect integrated circuit through resistance, electronic switch one termination power positive pole, another termination transistor G ₂Colelctor electrode, this colelctor electrode one tunnel connect integrated circuit through capacity earth, another road, and this transistor emitter stage connects positive source, base stage resistance grounded, insert signal transducer between this transistor emitter stage and the base stage.

The utility model signal transducer is loaded in the lock ring.

Compared with the prior art the utility model has apparent advantage, not only have original ring lock small volume and less weight, any crooked advantage of twining, also have after lock ring is cut off destruction, send chimes of doom in the lock body, thereby improved reliability, strengthened the function of lock.

Below in conjunction with accompanying drawing the utility model is elaborated.

Fig. 1 is that the utility model is formed schematic diagram;

Fig. 2 is the utility model lock body structure schematic diagram;

Fig. 3 is the utility model warning device circuit theory diagrams.

As Fig. 1, Fig. 2, shown in Figure 3.The utility model is made up of lock body 1, lock ring 3 and dead bolt 4.Electronic alarm device 2 is housed in the lock body 1, and this device is by power supply 21, alarm 22, from mat transformer 23, electronic switch 24, integrated circuit 25, transistor G ₁, G ₂And resistance R ₁, R ₂, capacitor C is formed, alarm with form a parallel circuit from the mat transformer, a termination power positive pole of this circuit, the other end is through meeting transistor G from mat transformer centre tap ₁Colelctor electrode C, this transistor emitter Q ground connection, base stage b are through resistance R ₁Connect integrated circuit, electronic switch one termination power positive pole, another termination transistor G ₂Colelctor electrode C, this colelctor electrode one tunnel connects integrated circuit through capacity earth, another road, and this transistor emitter stage a meets positive source, base stage b through resistance R ₂Ground connection is inserted signal transducer 26 between this transistor emitter stage and the base stage.Power cathode ground connection, utmost point ground connection of integrated circuit.Sensor is loaded in the lock ring.When locking, dead bolt is inserted within the lock body pin clamp 5, the interior lock pin of lock body this moment just pins dead bolt, lock can't be opened except that key.Because the sensor that is loaded in the lock ring is intact, so transistor G ₂A, the b utmost point between short circuit, this triode ends, no signal output, transistor G ₁End, alarm is not worked yet.When lock ring is cut off destruction, transistor G ₂Become open circuit between a, the b, this pipe conducting work, output signal is to integrated circuit, and integrated circuit output signal makes transistor G ₁Conducting, alarm work.

The utility model can be checked its work by electronic switch at ordinary times, inserts in the lock body pin clamp with a hard needle-like object of point, touches electronic switch, makes its connection, causes triode G ₁Conducting work, alarm work.

The utility model power supply is the button cell of 3V, and upward power consumption is little because this device designs, so a batteries can be used the long period, changes battery and also will could take out lock core with after key operated, changes battery.

The utility model is applicable to various bicycles, power assist vehicle, shop door lock, also can be used for going on business with on the traveling bag.
