Description
[technical field]
The utility model relates to a kind of lockset, more particularly relates to a kind of combination padlock that key cipher can be set arbitrarily and carry out status alert.
[background technology]
From ancient times to the present lock is indispensable friend during people live always, and our friend it always can be synchronous with the epoch, popular house door lock has two big classes on the current social: a class is that the twisting by traditional mechanical key realizes the unlatching of door and the mechanical door lock of locking; One class is by the unlatching of the driving realization door of electromagnetic force and the electronic lock of locking.The mechanical door lock structural principle is simple, clear, good reliability, whenever can both open easily, there is not absolute locked situation to take place, it meets people's custom used in everyday, yet its fatal shortcoming is a technology, and the anti-property opened is poor, no matter many high-grade, expensive mechanical door locks, adopt technological means all can open easily, thereby the popular machine that has MASTERKRY, " lock king " etc. to unblank specially on the market, therefore people are summarized as " firm door, fragile lock " to current ubiquitous this social present situation; And electronic lock action principle complexity, reliability are relatively low, in case power down or certain situation take place, absolute locked possibility are arranged just.
In view of above problem combination padlock arises at the historic moment.
[utility model content]
The utility model has overcome the deficiency of above-mentioned technology, provides a kind of and has gathered traditional mechanical lock and electronic lock repertoire, had password arbitrarily and reset and be provided with and carry out status alert, combination padlock simple for structure, easy for installation.
For achieving the above object, the utility model has adopted following technical proposal:
A kind of combination padlock that the utility model is related includes lock body, lock core and lock gall, it is characterized in that: also include controller, the memory that is connected with controller, digital key; Wherein, in the lockhole on described lock core respectively device automatically controlled pellet shot from a slingshot and signal pellet shot from a slingshot are arranged, controller can be connected with digital key in being inserted into lock gall by the signal pellet shot from a slingshot, and the digital chip that encrypted message can be set is housed in the digital key; Described controller can compare the encrypted message of encrypted message in the digital chip and the storage of memory Central Plains; When encrypted message was identical, then controller was controlled the action of automatically controlled pellet shot from a slingshot and is unblanked; When encrypted message was inequality, then controller control electric-control cylinder lock closed.
Aforesaid a kind of combination padlock, it is characterized in that: described signal pellet shot from a slingshot is divided into the number of winning the confidence pellet shot from a slingshot, control signal pellet shot from a slingshot, power taking signal pellet shot from a slingshot and control signal pellet shot from a slingshot all are made of the first bullet piece, the second bullet piece and the spring of metal material manufacturing, and the first bullet piece, spring and the second bullet piece connect in turn; The power output end DZ of the host CPU in the first bullet piece of power taking signal pellet shot from a slingshot and the controller is connected, the insulating point of the digital key that the second bullet piece is interior with being inserted into lock gall contacts, the first bullet piece of control signal pellet shot from a slingshot is connected with the signal input part RB0 of host CPU, and the signalling contact of the digital key that the second bullet piece is interior with being inserted into lock gall contacts.
Aforesaid a kind of combination padlock, it is characterized in that: described automatically controlled pellet shot from a slingshot by the armature that is provided with cavity, be placed on the magnetic core in the cavity and the coil that is wrapped on the armature is formed, two of described coil terminates on the power output end of the host CPU in the controller.
Aforesaid a kind of combination padlock, it is characterized in that: combination padlock also includes the alarm with the controller wireless connections, and sending out alarm signal according to controller realizes reporting to the police, this alarm includes receiver module, decoding circuit, display circuit, warning CPU, audible alarm circuit, voice alarm circuit, DTMF transmission circuit and telephone control circuit, receiver module, decoding circuit, warning CPU connects in turn, display circuit, audible alarm circuit, voice alarm circuit, the DTMF transmission circuit all is connected on the warning CPU, the alarm signal that receiver module wireless receiving sending module sends, decoding circuit is decoded to this signal, and warning CPU receives decoded alarm signal can pass through voice alarm circuit, telephone control circuit sends the audio alert signal; Warning CPU can also control audible alarm circuit and directly report to the police, and controls the state of display circuit display alarm simultaneously.
Aforesaid a kind of combination padlock, it is characterized in that: described controller includes host CPU and transmitter module, host CPU links to each other with digital key, automatically controlled pellet shot from a slingshot and memory, host CPU can be verified the encrypted message of digital chip in the digital key and can control automatically controlled pellet shot from a slingshot action, host CPU sends order to connected sending module, and sending module is to the wireless alarm signal of sending of alarm.
Aforesaid a kind of combination padlock is characterized in that: the host CPU in the controller is the PIC single-chip microcomputer, and its ground terminal GND is connected on the lock core; Signal output part RB4, RB5 link to each other with memory; Signal input part RA1 is provided with key D1 one end with key and is connected, and key is provided with key D1 other end ground connection; Signal output part RB1, RC0, RC1, RC2, RC3 are connected with transmitter module.
The beneficial effects of the utility model are:
1, since the utility model on the basis of mechanical lock structure form and repertoire, increased controlled automatically controlled pellet shot from a slingshot, this automatically controlled pellet shot from a slingshot is controlled by the password of digital key, except the legal key that combination padlock is confirmed, any key all can not open it, and technology prevents that the property opened, theftproof are good;
2, since digital key of the present utility model on the basis that keeps original mechanical key construction profile and whole tartars, interior device has 64 binary-coded digital chips, its number that contains of this 64 digital chip is globally unique code, and is not reproducible.Therefore even trillion of its quantity exceedances of digital key with this chip configuration can not repeat yet, and this number can not rewrite, and this has just guaranteed unique property opened of this kind door lock;
3, because the utility model adopts digital identification and memory technique, the key that can allow the simple deletion arbitrarily of user use, thus remove the user to losing the worry of key;
