Description

But private code theftproof lock

Technical field

The utility model relates to a kind of lockset, but relates in particular to a kind of private code theftproof lock.

Background technology

The lockset that uses in the family is mechanical mostly now, and these locksets all need to be equipped with corresponding key, and such lockset key on the one hand can be lost, in case key loss will be entered to owner and be brought very large trouble, on the other hand, safety is also enough, and key might be duplicated by the people.The someone had invented mechanical code lock afterwards, though mechanical code lock does not need to be equipped with key, avoided losing the inconvenience of key and by the risk of people's copy key, but this mechanical code lock generally has only a password that just configures from start to finish when dispatching from the factory, like this, under the situation of this cryptocompromise, can't change password and will make this mechanical code lock perform practically no function.

The utility model content

But technical problem to be solved in the utility model provides a kind of private code theftproof lock, to be convenient for people to use and to improve the theftproof performance of lockset.

In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:

But a kind of private code theftproof lock, comprise the lock body shell, have dead bolt cave and lock core in the lock body shell, described dead bolt is provided with dead bolt in the cave, and dead bolt is connected with lock core, it is characterized in that: also be provided with micromachine and single-chip microcomputer in the described lock body shell, described lock body case surface is provided with password key, have tooth bar on the described lock core, the rotating shaft of described micromachine is provided with and the tooth bar meshed gears, and described password key and micromachine all are electrically connected single-chip microcomputer.

Described password key includes 0～9 10 numeric keys, acknowledgement key and one key is set.

Adopt technique scheme, load onto working programme in the single-chip microcomputer in advance, earlier password be set by password key, with password storage in single-chip microcomputer, after but this private code theftproof lock is locked, if unblank, must re-enter password by key passwords, single-chip microcomputer will be inputed password and be stored in the interior password of single-chip microcomputer in advance and compare then, if comparison is correct, just open lock, if comparison is not inconsistent, lock or keyed.If password in use for some time, in order to prevent original password leakage that is provided with, can in time change password, at this moment as long as reset just passable by password key.Therefore, but private code theftproof lock of the present utility model can free setting code, has not only made things convenient for people to use lockset, has avoided people to use the trouble of mechanical lock band key, the safety that has also improved lock.

Description of drawings

Below in conjunction with the drawings and specific embodiments the utility model is elaborated:

Fig. 1 is a structural representation of the present utility model.

Among the figure:

1, lock body shell 2, dead bolt cave 3, lock core 31, tooth bar

4, dead bolt 5, micromachine 51, gear 6, password key

7, single-chip microcomputer

The specific embodiment

As shown in Figure 1, but private code theftproof lock of the present utility model comprises lock body shell 1, has dead bolt cave 2 and lock core 3 in the lock body shell 1, is provided with dead bolt 4 in dead bolt cave 2, and dead bolt 4 is connected with lock core 3.In addition, also be provided with micromachine 5 and single-chip microcomputer 7 in the lock body shell 1, lock body shell 1 surface is provided with password key 6, has tooth bar 31 on the lock core 3, the shaft gear 51 of micromachine 5, tooth bar 31 and gear 51 engagements, password key 6 and micromachine 5 all are electrically connected single-chip microcomputer 7.But should can adopt powered battery also can pass through a transformer as required by the private code theftproof lock by mains-supplied.

Password key 6 includes 0～9 10 numeric keys and acknowledgement key and one key is set.

But the working programme that makes this private code theftproof lock work is housed in advance in single-chip microcomputer 7.

But the working method of this private code theftproof lock is such: by password key 6 password is set earlier, with password storage in single-chip microcomputer 7, after but this private code theftproof lock is locked, if unblank, must re-enter password by password key 6, single-chip microcomputer will be inputed password and be stored in the interior password of single-chip microcomputer in advance and compare then, if comparison is correct, single-chip microcomputer 7 is just controlled micromachine 5 runnings, drives lock core 3 and drives in the dead bolt 4 indentation dead bolt caves 2, and lock is opened; If comparison is not inconsistent, lock or keyed.If password in use for some time, in order to prevent original password leakage that is provided with, can in time change password, at this moment as long as reset just passable by password key 6.Therefore, but private code theftproof lock of the present utility model can free setting code, has not only made things convenient for people to use lockset, has avoided people to use the trouble of mechanical lock band key, the safety that has also improved lock.

But, one skilled in the art would recognize that the above-mentioned specific embodiment is exemplary, be to be the restriction that this patent is comprised scope in order better to make those skilled in the art can understand this patent, can not to be interpreted as; So long as according to spirit that this patent discloses done anyly be equal to change or modify, all fall into the scope that this patent comprises.

Claims (2)

1. But 1, a kind of private code theftproof lock, comprise the lock body shell, have dead bolt cave and lock core in the lock body shell, described dead bolt is provided with dead bolt in the cave, and dead bolt is connected with lock core, it is characterized in that: also be provided with micromachine and single-chip microcomputer in the described lock body shell, described lock body case surface is provided with password key, have tooth bar on the described lock core, the rotating shaft of described micromachine is provided with and the tooth bar meshed gears, and described password key and micromachine all are electrically connected single-chip microcomputer.
