New bicycle series anti-theft alarm lock
Technical field
The utility model relates to a kind of anti-theft alarm lock, specifically is the anti-theft alarm lock that is applied in the bicycle series.
Background technology
At present, the bicycle alarming lock field on the domestic market does not have very superior function, has variety of issue.Existingly can be divided into following a few class substantially:
Existing electronic warning lockset much all is the principle that vibrations are reported to the police, promptly after the bicycle parking locking, enter the state of alert, produce collision when closing on bicycle and carry out false alarm but be easy to get at other people, can bring unnecessary trouble like this, and collide the bicycle lock that shakes principle and in releasing process, generally all can use remote controller, emission reception waits the adding of device will certainly increase the cost of bicycle lock.
The product that also has is to adopt electromagnetic induction principle that the release action of lockset is driven, and must increase cost of production like this, has also reduced the reliability of using.If lockset just gets rusty in the rainy day, the operating efficiency of electromagnetic traction magnet will be reduced.
Some product is that pure dependence electrical principles designs on principle, lacks the frame for movement of conventional lock is improved, and single antitheft form will reduce the difficulty that cracks of theft.
According to public security department's statistics, bicycle or electric motor car robber generally can adopt key, the drill bit destruction lock core of special construction or the method for cutting short that traditional mechanical lock is destroyed.Conventional lock is general can be not exhaustive to the protection of above these several mode of failure.
Summary of the invention
At above-mentioned problem, the utility model provides a kind of novel structure, easy to use, firm relatively new bicycle series anti-theft alarm lock.
A kind of new bicycle series anti-theft alarm lock comprises shell, lock core and hammerlock, and lock core is provided with one group of pellet shot from a slingshot, the top of described lock core also is provided with one group of pellet shot from a slingshot, be preferably one, shell is provided with cryptographic key, and is provided with control, warning circuit in lock inside.
Described control, warning circuit are set to: comprise a surface-mounted integrated circuit, comprise on the surface-mounted integrated circuit six d type flip flops, counter, with door, NAND gate and oscillator; NAND gate is provided with the break alarm line, and the break alarm line runs through hammerlock; Be connected cryptographic key with door; Be respectively arranged with connecting line on the shell at pellet shot from a slingshot and pellet shot from a slingshot rear portion, connect and door.
Described break alarm line has used in fields such as notebook computers as prior art, the general enamel-covered wire that adopts, on the U-shape lock arm, open an about sulculus of one millimeter, round end from hammerlock after the enamel-covered wire doubling is stretched out, the other end gos deep into the position that hammerlock is stuck, enamel-covered wire disconnects when hammerlock is cut off like this, alarm equipment alarm.
Adopt cryptographic key to increase the safety of lock, adopt existing foolproof password setting mode, just several cryptographic keies are connected respectively to and door, password is set according to its arrangement.
The shell at pellet shot from a slingshot and its rear portion is provided with connecting line, and is connected with door, and pellet shot from a slingshot that as required can top is set to master switch, conducts electricity by key, is communicated with other pellets shot from a slingshot then, and then with the entire circuit connection, just can unblanks.Realize this step, way is also fairly simple, the shell of pellet shot from a slingshot can be covered with non-conducting material, or pellet shot from a slingshot is whole with wear-resisting nonmetals (as pottery) making, the center is made cavity and is passed through lead.
Like this, when unblanking if desired, at first need to insert key, satisfy shape need after, circuit communication can not reported to the police, and could carry out the unlatching of password again, if touched wrong password, then reports to the police; If attempt different passwords, then can be set time delay, promptly report to the police after the time of advent; Then could key, finish and unblank.
New bicycle that the utility model provides series alarming lock has adopted new lock core structure and electronic circuit warning structure, have volume little, be easy to preserve; Operate fairly simplely, common people can learn; Security reliability improves greatly, and difficult quilt is stolen; Low in energy consumption, advantages such as battery long service life.

The specific embodiment
Further explain, illustrate the technical program with non-limiting embodiment below.
A kind of new bicycle series anti-theft alarm lock as shown in Figure 1, comprises shell 1, lock core and hammerlock, lock core is provided with one group of pellet shot from a slingshot 2, and the top of described lock core also is provided with one group of pellet shot from a slingshot 3, is preferably one, shell is provided with cryptographic key, and is provided with control, warning circuit in lock inside.
As shown in Figure 2, described control, warning circuit are set to: comprise a surface-mounted integrated circuit, comprise on the surface-mounted integrated circuit six d type flip flop 74LS175, counter 74LS162, with door 7411, NAND gate 74LS00 and oscillator NE555; Six d type flip flop 74LS175 are used to keep alarm signal, and NAND gate 74LS00 is used to judge whether the break alarm line is destroyed, and it is provided with the break alarm line, and the break alarm line runs through hammerlock; Be connected cryptographic key with door 7411, judge whether the condition of unblanking meets; Be respectively arranged with connecting line on the shell at pellet shot from a slingshot and pellet shot from a slingshot rear portion, connect and door.Corresponding keys such as switch S 1, S2, S3 are as the line of conductor conducting pellet shot from a slingshot afterbody; Switch S 4-S9 is as cryptographic key, and the number that specifically accesses to your password and which button trigger and effectively can be provided with flexibly; Its frequency of oscillation of NE555 is the foundation of time-delay length.
Described break alarm line has used in fields such as notebook computers as prior art, the general enamel-covered wire 5 that adopts, on the U-shape lock arm, open an about sulculus of one millimeter, round end from hammerlock after the enamel-covered wire doubling is stretched out, the other end gos deep into the position that hammerlock is stuck, enamel-covered wire disconnects when hammerlock is cut off like this, and alarm 6 is reported to the police.
Adopt cryptographic key to increase the safety of lock, adopt existing foolproof password setting mode, just several cryptographic keies are connected respectively to and door 7411, password is set according to its arrangement.
The shell at pellet shot from a slingshot and its rear portion is provided with connecting line, and is connected with door 7411, and the pellet shot from a slingshot 3 of top can be set to master switch as required, conducts electricity by key 4, is communicated with other pellets shot from a slingshot 2 then, and then with the entire circuit connection, just can unblanks.Realize this step, way is also fairly simple, the shell of pellet shot from a slingshot can be covered with non-conducting material, or pellet shot from a slingshot is whole with wear-resisting nonmetals (as pottery) making, the center is made cavity and is passed through lead.
Like this, when unblanking if desired, at first need to insert key, satisfy shape need after, circuit communication can not reported to the police, and could carry out the unlatching of password again, if touched wrong password, then reports to the police; If attempt different passwords, then can be set time delay, promptly report to the police after the time of advent; Then could key, finish and unblank.
