Abstract

The utility model discloses a multifunctional electronic theft-proof lock which is a confidential circuit composed of a low grade digital circuit and a plurality of NOT gate circuits. An alarm circuit of a note magnification circuit is controlled by that multiple input OR-gate circuits are matched with multiple sensors, unlocking adopts the time protection and a keyboard and a lock body are separated and inserted. The utility model has the advantages of novel and reasonable design, simple structure, stable and reliable performance and high security, and has multiple anti-theft functions.

Description

The multifunctional electronically anti-theft lock

The utility model relates to the multifunctional electronically anti-theft lock of a kind of electronic cipher digital circuit and anti-theft warning circuit combination.

In existing many electronic safety locks, generally adopt controllable silicon to gang up, circuit is established the method for card, and it is simple in structure, easy to operate, performance is also more reliable, but confidentiality is poor, is penetrated easily, the employing computer control that has, it is with high content of technology, but cost is more expensive, is difficult to apply.

The purpose of this utility model is that design is a kind of simple in structure, stable performance, and escape is convenient, and security performance is good, and the electronic safety lock of characteristics such as multiple warning function is arranged, and this electronic safety lock is suitable for various motor vehicles and house office door.

The design of multifunctional electronically anti-theft lock is: multistage digital circuit and many group NAND gate circuits are formed secure circuit; unblank to adopt guardtime; report to the police and adopt many input OR circuits to cooperate multichannel to pass the control audio amplifier circuit of growing up to be a useful person, keyboard and lock body adopt discrete grafting form.

Add explanation below in conjunction with Figure of description to the utility model is auspicious.

Figure of description is the circuit theory diagrams of multifunctional electronically anti-theft lock, among the figure: IC-be special module, form exportable 0-9 0 every grade single signal, F of driving by multistage+system counting circuit ₁Be multichannel input nand gate circuit, its way is decided by special module progression, F ₂One F ₅Be 42 input nand gate circuit, constitute and unblank or the false touch warning F ₆For many inputs or gate cell circuit, be used to control the audio alarm circuit, S is multiple sensor (comprising torsion, pressure, pulling force, magnetosensitive, light idol etc.), K ₁Be job key, K ₂Be unlock key, (K ₃, K ₄) be reset key, (K _aK _b) for failing sign indicating number key, R ₁3.3K, R ₂200, R ₃470K, R ₄1K, C ₁100 μ, C ₂56 μ, D ₄091, BG9015, BG ₂8050, J-relay or electromagnet etc. are formed executing agency with dead bolt.

During assembling, keyboard flexible cord plug is inserted each function socket place of circuit, F respectively ₁Input plug inserts special module jacks at different levels respectively, and numeral can be selected combination arbitrarily, and for example: A is inserted in " 5 " and locates, and B is inserted in " 8 " and locates, and other all is inserted in " 9 " and locates, and the red key of setting in the keyboard is K _a, Lan Jian is K _b, green key is K _Q, Huang Jian is K _b(colorful key is also same with A, B, C letter).During operation, red key is by 1 time (at this moment, G point be a positive potential, IC switch on work), and green chain is pressed 5 times, and Huang Jian presses 8 times (F at this moment, ₁A, B obtain positive voltage and work), again by blue key (F at this moment, ₄Work, BG conducting, J work), withdrawal body in, leave, work as operate miss, touch logical reset key automatically by lock for the lock house, or number is when inputing by mistake, and lock can not leave during by blue key, and F ₇Conducting, F ₈Obtain negative voltage, can trigger warning circuit and report to the police, circuit is provided with the guardtime function.As by behind the red key, should expertly once finish the button unlock operation, surpass time rating (5-56 seconds, by R ₆Regulate), IC outage automatically enters reset mode.

When multifunctional electronically anti-theft was locked in and uses, door lock and music door-bell or entryphone were formed one, used the AC and DC power supply of automaticallying switch, establish force open the door, brute force pushes warning, other uses external control line, magnetic switch.Pulling force sensors etc. are controlled balcony, window and the position of entering the room easily, but cooperative mechanical tapered end extended use also is service industries such as large-scale hotel, both can be convenient to client and adjust password oneself and unblank, and can be convenient to waiter again and open the lock with the key.When this lock is used for motor vehicles, can control power supply, fuel tank, tool box, steering wheel, tap etc. and need the control position, as long as main lock is opened, other tapered end one is by promptly opening, employing is with Che Qiangsheng, high light and radiowarning mode (in 300 meters, the car owner will receive the warning etui and take with oneself just), can prevent picking lock, tear lock open, trimming, promote, pound the door, pilferage behavior such as pivot frame, switch power supply case.

The multifunctional electronically anti-theft lock is rationally novel in design, and simple in structure, stable and reliable for performance, strong security has multiple anti-theft feature, and certain market prospects are arranged.

Claims
