Abstract
The utility model discloses a double-anti-theft lock which comprises a lock case, and further comprises a password control unit and a key cylinder (2) of a key rotary control mechanism (1), wherein a keyhole (3) and an external interlock plunger (4) are arranged in the key rotary control mechanism, the double-anti-theft lock further comprises a relay (5) which is electrically connected with the password control unit, the relay is provided with a telescopic ejector pin (6), and the ejector pin is of a pin body which blocks the block plunger from unlocking in an extension state and releases the block plunger to unlock in a retraction state. The double-anti-theft lock has a strong anti-theft function, and is safe and practicable, the unlocking process can be realized through matching the password control unit with the key rotary control mechanism together, when the key rotary control mechanism is only used, the password control unit does not carry out control retraction on the ejector pin of the relay and keeps the ejector pin in the extension state, so the ejector pin in the extension state can block the lock plunger from rotating, and thus, unlocking cannot be realized; and consequently, a thief can be effectively prevented from technically unlocking through self-made tools, and the double-anti-theft lock is safe and practicable.
Description
Technical field
The utility model relates to a kind of theftproof lock, relates in particular to a kind of dual anti-theft lock.
Background technology
At present; The theftproof lock of supporting password, fingerprint and three kinds of modes of mechanical key to implement switch is accepted extensively by market; Yet this type theftproof lock of the prior art, an operation is arranged in the process of unblanking is that correct can realizing unblanked as long as its crypto control unit, fingerprint control device and key revolve control mechanism, does not have restricting relation each other; Use the instrument of preparation voluntarily to carry out skilled unlocking like the robber; Then can't guard against theft at all, three kinds of modes are that user friendly unblanking selected, anti-theft feature is not enough, poor stability.
The utility model content
In view of this, the utility model technical problem to be solved is: provide a kind of anti-theft feature strong, safe and practical dual anti-theft lock.
In order to achieve the above object, the utility model adopts following technical scheme to realize:
A kind of dual anti-theft lock; Comprise the lock shell, also comprise having the lock core that crypto control unit and key revolve control mechanism, said key revolves has keyhole in the control mechanism, outer chain bolt; Wherein, Also comprise the relay that is electrically connected at said crypto control unit, said relay has telescopic push rod, and said push rod is at the body of rod that stretches out the said locking bolt release of letting pass under the said locking bolt release of block, the retracted mode under the state.
Can know that by technique scheme the beneficial effect of the utility model is:
Compare prior art, the utility model anti-theft feature is strong, safe and practical, particularly; The process of unblanking must have crypto control unit and key to revolve the dual cooperation of control mechanism could to realize; When only relying on key to revolve control mechanism, withdraw but keep it to be in the state of stretching out because crypto control unit is not implemented control to the push rod of relay with, so; Stretch out the rotation of the push rod meeting block locking bolt of state; Thereby can't release, can effectively defend the robber to use the instrument of preparation voluntarily to carry out skilled unlocking thus, safe and practical.

The specific embodiment
In order to make those skilled in the art can further understand the characteristic and the technology contents of the utility model, see also following detailed description and accompanying drawing about the utility model.
See also shown in Figure 1ly, the utility model provides a kind of dual anti-theft lock, comprises lock shell (not shown); Also comprise and have the lock core 2 that crypto control unit and key revolve control mechanism 1; Said key revolves has keyhole 3 in the control mechanism, outer chain bolt 4, wherein, also comprises the relay 5 that is electrically connected at said crypto control unit; Said relay has telescopic push rod 6, and said push rod is at the body of rod that stretches out the said locking bolt release of letting pass under the said locking bolt release of block, the retracted mode under the state.
In the utility model, said crypto control unit can not add qualification at this for numerical ciphers control device, finger-print cipher control device or other crypto control units.
But the preferable possible embodiments that the above is merely the utility model is not the claim in order to limitation the utility model, so the equivalent structure that all utilization the utility model manuals and accompanying drawing content are done changes, all in like manner is included in the scope of the utility model.
