Description

A kind of mechanical and electronic compound lock head
Affiliated technical field
The utility model relates to a kind of tapered end, particularly relates to a kind of tapered end that contains electronic cipher.
Background technology
In the lockset industry, mechanical lock is easily by skilled unlocking, poor safety performance, the lockset of machinery and electron recombination, its dead bolt was not only spacing but also can be spacing by electronic lock by mechanical lock, and the key of mechanical lock and electronic lock must be correct simultaneously, could open by a lock, therefore has good safe antitheft performance, but mechanical and electronic combined double-protection lock set on the market, its mode of unblanking will be removed electronic lock earlier, opens mechanical lock with mechanical key again, need twice operating process, inconvenient operation.
In the burglar alarm field, as the patent No. is the disclosed a kind of warning tapered end of Chinese patent of ZL97232282, it can be opened lockset to the violence damage tapered end and produce warning, but it can't produce warning to the technical unlocking mode by master key or cover lock tool rotational lock core.And for example the patent No. is that the Chinese patent of ZL99240760 discloses a kind of warning tapered end, the electronic cipher chip though key has been packed into, can open or close warning system by checking electronic cipher, but it transmits electronic cipher by two contact points that expose on the shank of the key, make circuit be exposed to the tapered end surface, destroyed the circuit in the lock and warning system was lost efficacy by external power easily, and whether it can't detect lock core and rotate.
The utility model content
The purpose of this utility model is to provide a kind of mechanical and electronic compound lock head of safe and reliable and use aspect.
The mechanical and electronic compound lock head that the utility model provides comprises tapered end and key two parts, and tapered end comprises tapered end shell and lock core, and lock core is enclosed within the tapered end shell, and lock core is connected with a shift fork, has the hole that communicates with lock core, built-in electric conductor on the tapered end shell in addition; Be provided with the keyhole that communicates with tapered end shell inwall at the lock core edge; The parts that contain electronic cipher information are housed in the key, the corresponding tartar of pellet shot from a slingshot in its positive setting and the lock core, reverse side is provided with conductive contact points.
Be provided with dielectric isolation layer between electric conductor described in the utility model and the tapered end shell, the end that electric conductor is relative with lock core stretches out and a little more than tapered end shell inwall, the other end is associated with elastomeric element and electrical connecting wire.
Contact point described in the utility model is electrically connected with the key insulation and with the parts that contain electronic cipher information.
The set positions of electric conductor described in the utility model must be rotated a certain angle contact point again after key inserts lock core could contact pairing position with electric conductor, the more excellent scheme of the angle initialization that rotates is between 30 °-90 °, also can be set in key and insert and must not rotate contact point behind the lock core and just can contact pairing position with electric conductor.
The utility model with the corresponding outer wall of lock core circumference of electric conductor on, insulating point with the lock core insulation can be set, electric conductor withstood on the lock core metallic conduction part when first kind of set-up mode was locking, when unblanking, electric conductor leaves lock core metallic conduction part, and by this insulating point, promptly electric conductor has the process that insulate with lock core in the lock core rotating process, electric conductor withstood on this insulating point and insulate with lock core when second kind of set-up mode was locking, when unblanking, in the lock core rotating process, electric conductor leaves this insulating point and partly contacts with the lock core metallic conduction.
Electric conductor described in the utility model, it is provided with quantity and can decides according to the characteristic of the electronic cipher chip that is adopted, it can be one, also can be a plurality of, be provided with under one the situation that the earth terminal of electronic cipher parts is connected conducting with key, be provided with under a plurality of situations, the earth terminal of electronic cipher parts can be connected conducting with key, also can not connect conducting, and is simultaneously corresponding with electric conductor quantity and position in the reverse side of key set contact point quantity and position.
The parts that contain electronic cipher information described in the utility model can be installed separately with contact point, and are electrically connected with contact point, also can be packaged into one with contact point and be installed on the key.
The course of work of the present utility model: when key inserts, pellet shot from a slingshot in its front tartar and the lock core adapts, lock core and key can rotate, the linkage shift fork, after lock core forwarded certain angle to together with key, electric conductor can contact conducting with contact point on the key under the effect of elastomeric element, and the encrypted message of electronic cipher parts is sent to single-chip computer control system by electric conductor and the lead that connected thereof, correct as password, electronic lock partly allows to unblank or warning system is not reported to the police; As password bad, warning that the electronic lock part does not allow to unblank or warning system is triggered.If on the circumference of outer wall of lock core and electric conductor corresponding point, be provided with insulating point, under the situation that adopts first kind of set-up mode: during locking, since electric conductor with contact conducting with lock core, i.e. electric conductor this moment conducting over the ground, after lock core rotates, electric conductor leaves lock core and contacts with insulating point promptly and not conducting of earth polar, two kinds of different conditions of this of electric conductor make single-chip computer control system can detect the different signals of telecommunication under corresponding circuit cooperates, therefore just can judge also whether lock core rotates, be outer unblanking or drawback lock; Under the situation that adopts second kind of set-up mode: during locking, since electric conductor and not conducting of lock core promptly with not conducting of earth polar, after lock core rotates, electric conductor leaves insulating point and contacts conducting with lock core, i.e. electric conductor this moment conducting over the ground, two kinds of different conditions of this of electric conductor also can make single-chip computer control system detect the different signals of telecommunication under corresponding circuit cooperates, and therefore just can judge also whether lock core rotates, and are outer unblanking or drawback lock.
The beneficial effects of the utility model: the function of the existing mechanical lock of the utility model, the function that Electronics Cryptographic Keys is arranged again, can realize the lockset two-way safeguarding function easily, mode of operation is simple and convenient, whether can also conveniently realize detecting lock core rotates, make SCM system can distinguish outer unblanking or drawback lock, be well suited for being applied in illegal unlatching lockset is sent in the electronic warning system of warning.Simultaneously, electronic cipher and single-chip computer control system to contact the conducting parts hidden in the internal construction of tapered end, have and prevent preferably the performance of lockset electric shock destruction with violence damage, partly adopt reverse locking mode (when being locking for electronic lock, executing agency is not spacing to dead bolt, detected electrons password again in the process of unblanking, correct as password, executing agency is failure to actuate, allow to unblank, as incorrect, executing agency is just spacing with dead bolt) the mechano-electronic Lock with double safety guard have significant effect.
Below in conjunction with the drawings and the specific embodiments the utility model is further described.
