On the other hand, in prior art, mechanical code lock is had it long ago, and the electronic type cipher key is also had it long ago, but their structure is all more complicated, makes trouble, and cost is high, and its safety is also not bery high, is not easy to promote the use of.And the mechanical code key is the prior art blank.
Summary of the invention
The object of the invention is to: a kind of assembled key of mechanical lock and production new technique are provided, can replace the single-piece of having continued to use more than one thousand years and make the key production method, greatly simplify manufacturing process, control for the modernization of key production and artificial intelligence and lay the first stone.
Technical scheme of the present invention is: a kind of assembled key of mechanical lock is provided with a plurality of centers the tooth base of through hole, a screw rod, is provided with nut on key handle; Be provided with a plurality of teeth position of different directions on the same axial cross section of tooth base, described a plurality of tooth bases pass its central through hole by screw rod and are threaded with nut on key handle.
The height of described tooth position all arranges with sustained height base.
Production technology of the present invention is: the first step, and whole key is decomposed add independently key handle of engineering, a plurality of tooth bases;
Second step all synchronously arranges a plurality of teeth position of different directions on the axial cross section of tooth base;
In the 3rd step, all open the through hole in same base footpath at the center of tooth base;
In the 4th step, to the vertical distance of tooth top, the height of each tooth position is set by unified altitude datum unit all with the center of tooth base on the tooth position of different directions;
In the 5th step, be fixedly installed nut on key handle;
In the 6th step, the independent setting can be used for the screw rod that a plurality of tooth bases and key handle are connected as a single entity;
The 7th step, the unlocking cipher that is arranged to form key of numbering with the calibrated altitude of the order numbering of a plurality of teeth position on the succession of a plurality of tooth bases numbering and tooth base and each tooth position.
The present invention is based on the basic principle of Modern Manufacturing Industry, standardization, seriation, standardization etc. are applied to the key manufacture process, founded the concept of tooth base, after the tooth base is carried out standardization, seriation, standardization, adopt the process that the tooth base is assembled into key, proposed brand-new key production new technique.
The present invention is resolved into a plurality of standardized tooth bases with whole key, key handle, adapted screw rod, nut, then with tooth base specification series, on this basis, choose at random the tooth base and be assembled into various keys, will be assembled into personnalité key without the tooth base combination of individual character, simplified widely the key manufacturing process.
1, tooth base
Referring to figure one, be a common common key, be whole shape.Referring to figure two, it is the tooth base that the whole key in figure one is resolved into.The main part of key is tooth, and the height difference correspondence of these teeth the pellet that varies just, has just given play to the security function of " opening different locks with different keys ".But the backwardness of the personalized mode of production of key also comes from this.The tooth base is exactly the matrix of a tooth, and the key in figure one has five teeth, just can resolve into five tooth bases in figure two.Referring to figure three, it is exactly a tooth base of cross key.
2, tooth position
The tooth position is one of key element of tooth base.It is the number of teeth that has on the same cross section of key.General flat key only has a direction that tooth is arranged, so only have a tooth position.Referring to a in figure four figure, the cross key is having tooth (being that four teeth are arranged on same cross section) on four direction, so four tooth positions are arranged.
3, tooth depth
Tooth depth be the tooth base key element two.Corresponding different pellet, tooth on the key has different height, and this is the key point that marble lock key is unblanked.The height of this tooth that tooth depth just refers to, for the cross key, tooth depth refers to that the center line of key is to the vertical distance of tooth top.
Five kinds of tooth depths of cross key that Fig. 4-2,4-3,4-4,4-5,4-6 are exactly standardization, seriation.The tooth depth that to get a unit height be E type tooth, unit tooth depth of every increase just changes a flute profile successively, and D type tooth is two unit tooth depths, and C type tooth is three unit tooth depths, and the Type B tooth is four unit tooth depths, A type tooth is five unit tooth depths.Each tooth base of cross key has four tooth positions, and the tooth depth on each tooth position has five kinds of A, B, C, D, E can supply its selection.Like this, with regard to the cross key, tooth base has four tooth positions, each desirable five kinds of tooth depth in tooth position, and the permutation and combination of these teeth position, tooth depth has just formed the tooth base of different tooth depth sizes.As can be known, the species number of various tooth bases is:
5·5·5·5＝625
4, profile of tooth
Several tooth bases are combined, and the tooth depth of each tooth base of same tooth position is different, has just formed the profile of tooth that just rises and falls.Flat key has a toothrow shape, and the cross key has four toothrow shapes.Profile of tooth is the embodiment of key individual character, only has when every toothrow shape when pellet in corresponding lock core all coincide, and key just can be unblanked.The conversion of key is exactly in fact the conversion of profile of tooth.Advantage of the present invention: the safety of (one) key
1, the uniqueness of key
The key of producing by manual formula at present, two locksets of the same model that same producer produces, same specification occur available same as the phenomenon of key unlocking sometimes, and obviously this is potential safety hazard.This technique has been stopped this potential safety hazard.
If be comprised of five tooth bases by each cross key, can form different types of key number is the number of combinations of optional 5 kinds of tooth bases in 625 kinds of tooth bases.Can be calculated as follows according to the permutation and combination formula,
Type of key number=625! / (625-5)! / 5!
＝625！/620！/5！
＝(625·624·623·622·621)/120＝623·1255351500
As seen, this is a very large numeral, comes random combine assembling lockset and key by this, and the combination that duplicates is impossible basically, two locksets namely occur but phenomenon with identical key is almost impossible.Here it is produces key with this technique and greatly improves to the safety that lockset brings, and key is unique.
2, the password of key
This assembled key also has a kind of safety guarantee of cipher key, makes to pick up or steal the key person is not knowing can't to use this key unlocking in the key cipher situation.Referring to figure six, specific practice is:
(1) aborning four tooth positions of each tooth base are all put signs on, as first, second, third, fourth;
(2) choose five tooth bases and be assembled into a key, under the condition that can unblank, the mark of these five tooth bases on the flank of tooth of some appointments has a definite sequence, as first, the fourth on given side in figure six, second, fourth, third;
(3) this essence is exactly the tooth order password of this key, only has the tooth order when this key to be such state, just can unblank.Key holder and know mark order (being password) on this given side through the talent that he authorizes;
(4) can first loosen nut transfer disorderly above-mentioned mark order at ordinary times, then tightening nuts, at this moment the tooth order of key is entanglement, can not unblank.Transfer again along password when needing to use, can unblank.
The key cipher that Here it is only has assembled key just to have has brought the very large sense of security for key end user (particularly easily losing the children crowd of key).
There are following two doubts to be removed.
One, because key is that standard component (tooth base) is assembled, may bring a kind of unsafe sensation to the people: anyone can buy privately standard component and come bitting steathily to unblank.In fact, this doubt is unnecessary.As previously mentioned, key is comprised of five tooth bases, and each tooth base chooses from 625 kinds of tooth bases at random, and namely some tooth bases will guarantee to select right, just have 625 kinds to select method, and it is right that the people who does not know password will select five tooth bases, and examination selects number of times to be
625·625·625·625·625＝625
5
Will only look for password with the examination choosing in such astronomical figure, be impossible.
The another kind of unsafe sensation that two, may bring to the people: so, after anyone knows password from improper channel, can be easy to privately assemble key and unblank.In fact, this doubt is also unnecessary.As in like manner above-mentioned, even there is the people to know that first mark of password is first, but this first can not illustrate any problem, and just in first, second, third, four marks of fourth, in 625 kinds of tooth bases, have on each tooth base and be carved with the mark first on some.Other four tooth base marks therewith in like manner, the number of combinations that fits in the password mark is
625/4·625/4·625/4·625/4·625/4≈156
5
This is also an astronomical figure, therefrom only use password with the examination choosing, and be also impossible.
Mechanical code lock is had it long ago, and the electronic type cipher key is also had it long ago, but the mechanical code key this be to occur first.Cipher key is the entity of password and key, must grasp simultaneously key and password just can be unblanked, and only knows that its one is of no avail.
(2) versatility of key
According to the concept of the principle of above-mentioned key cipher and shaped as key bit as can be known, any one assembling cross key, behind its one of some tooth base rotation tooth position with regard to conversion profile of tooth, in fact just become another key.If prepare consciously aborning corresponding lockset, just realized that a key can drive the lock of two different appointments, or even many lock of different appointments.This brings great convenience to the public place administrative staff.The administrative staff of classroom, warehouse storehouse, hotel guest-room are subjected to key too many tired deeply at present.Use this technique this key of customization and lockset, just can accomplish a plurality of door locks totally one key, greatly reduce management work intensity.In fact, this application also can be generalized to the general population, and the carry-on key of exempting the public is tired.
(3) convenience of preparation
This fabricated standard key is also given in key loss or is prepared new key after damaging again and brings great convenience, as long as buy corresponding tooth base, gets final product by original assembled in sequence together, has overcome the inconvenience of present cross key-cut.
(4) promote industrial progress
The tooth base can be made concrete regulation (it is a unit tooth depth that 0.5 millimeter is got in the present invention's suggestion) to a unit tooth depth according to the size of lock body size, can form product standard.In like manner, can on the basis of key shape standard, form the product standard of tooth position number and size.This just can accomplish standardization, seriation, the standardization of key product, and on this basis and then form the key industry standard.
Because the development of present precise machining process is ripe day by day, the cold-drawn of the production technology employing new and high technology content of tooth base, cold forging, precision forging etc. are multiple without the surplus process technology, this will greatly reduce material consumption and increase substantially production efficiency, realize industrial progress.
Key is complementary products and the auxiliary products of lockset, and the industrial progress of key must drive the industrial progress of lockset.Standardization, seriation, standardization due to tooth depth, the pellet size supporting with tooth depth also realizes standardization, seriation, standardization thereupon, and then be the tapered end parts such as internal cylinder, outer lock core, its result will drive standardization, seriation, the Normalization that whole lockset is made.
