Abstract
A bicycle lock with guard and alarm functions comprises a lock body and an alarm circuit consisting of battery, switch and resistances connected in series. It is characterized in that the U shaped rod of the lock body is equipped with a conducting wire, and the conducting wire is connected in the circuit in series; the alarm circuit comprises a series circuit which is conneted by an integrated circuit module and a loudspeaker; the series circuit, the lock body and the resistances are connected in parallel at the end of battery and switch. The alarm circuit includes one triode transistor, and the collector of the triode transistor is connected with the integrated circuit module, the emitter and the base are connected at the two terminals of the resistance. Compared with the prior art, the utility model still adopts bayonet structure with only adding an alarm circuit, and can emit alarm signal when the lock is cut, thereby intimidating the thief and preventing the bicycle from being stolen.
Description
Technical field
The utility model relates to a kind of bicycle lock, especially relates to a kind of bicycle lock with anti-theft alarm function, is to the improvement of existing bicycle lock structure, belongs to the lockset manufacturing technology.
Background technology
At present, the lock of the used bicycle of people is the inserting bolt type bicycle lock mostly, and the rim of wheel in the empty stomach of insertion lock body pins bicycle before or after promptly passing with the U-shaped inserted link.Though this inserting bolt type bicycle lock is elegant in appearance, also easy stolen car people keeps a close watch on, and after with hand vice the U-shaped inserted link being cut off car is stolen.
The utility model content
The purpose of this utility model is to overcome the prior art above shortcomings, improve by research, provide a kind of bicycle lock with anti-theft alarm function, this novel bicycle lock still adopts the inserting bolt type structure, just set up warning circuit, when this bicycle lock is cut off by the people, can send alarm signal, reach and remind car owner and threatening to steal the car people, thereby guarantee that bicycle does not go adrift.
The technical solution that the utility model provides is, this bicycle lock with anti-theft alarm function, include a lock body and by battery, switch, the warning circuit that resistance is composed in series, the U-shaped inserted link that is characterized in described lock body is provided with lead, this lead is connected in the warning circuit, also has the series circuit of forming by integrated circuit block and loudspeaker in the described warning circuit, this series circuit and lock body, the resistance parallel connection is attempted by battery, the two ends of switch, also has a triode in the described warning circuit, the colelctor electrode and the integrated circuit block of this triode join, and its emitter stage and base stage are connected on the two ends of resistance.
Compared with prior art, the beneficial effects of the utility model are: still adopt the inserting bolt type structure, just set up warning circuit, can send alarm signal when this bicycle lock is cut off by the people, reach and remind car owner and threatening to steal the car people, thereby guarantee that bicycle does not go adrift.
Description of drawings
Accompanying drawing is the circuit theory schematic diagram of the embodiment that provides of the utility model.
The specific embodiment
The example that provides below in conjunction with accompanying drawing is described further structure of the present utility model:
As shown in the figure, this bicycle lock with anti-theft alarm function, include a lock body 1 and by battery 2, switch 3, the warning circuit that resistance 4 is composed in series, the U-shaped inserted link of described lock body 1 is provided with lead 5, this lead 5 is connected in the warning circuit, also has the series circuit of forming by integrated circuit block 6 and loudspeaker 7 in the described warning circuit, this series circuit and lock body 1, resistance 4 parallel connections are attempted by battery 2, the two ends of switch 3, also has a triode 8 in the described warning circuit, the colelctor electrode of this triode 8 and integrated circuit block 6 join, and its emitter stage and base stage are connected on the two ends of resistance 4.
When people's bicycle parking, earlier switch 3 is pressed, because lock body 1 is in parallel with loudspeaker 7, constitute the loop of battery 2, resistance 4, switch 3 and lock body 1 this moment, in case the thief cuts off the U-shaped inserted link with hand vice, promptly lock body 1 is cut off, and has then formed the loop of battery 2, switch 3, integrated circuit block 6 and loudspeaker 7, so loudspeaker 7 sends alarm signal, remind the car owner to note the safety of bicycle.
