Description

A kind of mechanical lock assembling key and production technology

Technical field

The present invention relates to the mechanical type cylinder lock set, specifically is a kind of mechanical lock assembling key and production technology.

Background technology

Present mechanical lock manufacturing had developed into modern industry already, but since with the personalized requirement of the supporting key of lockset, make the key manufacturing technology also be in the workshop stage, this phenomenon has restricted the modernization of whole lockset industry.Shown in figure one, it comprises key handle and a plurality of teeth that are connected as a single entity with it to the supporting key of existing mechanical lockset mostly, and the height difference correspondence of these teeth the pellet shot from a slingshot that varies, and has just given play to the security function of " opening different locks with different keys ".Several tooth bases are combined, and the tooth depth difference of each tooth base of same tooth position 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, have only when every toothrow shape when pellet shot from a slingshot in the corresponding lock core all coincide, key just can be unblanked.The conversion of key is exactly in fact the conversion of profile of tooth.But the backwardness of the personalized mode of production of key also comes from this.Flat key-cut is eaily.But because its safety is not high, at present widely used is the cross key, and the preparation of cross key is relatively more difficult.

On the other hand, in the 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 complicated, makes trouble, the cost height, and its safety is also not really high, is not easy to promote the use of.And the mechanical code key is the prior art blank.

Summary of the invention

The objective of the invention is to: a kind of mechanical lock assembling key 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, simplify manufacturing process greatly, for the modernization and the artificial intelligence control of key production lays the first stone.

Technical scheme of the present invention is: a kind of mechanical lock assembling key is provided with a plurality of centers the tooth base of through hole, a screw rod, and key handle is provided with nut; The same axial cross section of tooth base is provided with a plurality of teeth position of different directions, and described a plurality of tooth bases pass its central through hole by screw rod and are threaded with nut on the key handle.

The height of described tooth position all is provided with sustained height base.

Production technology of the present invention is: the first step adds independently key handle of engineering, a plurality of tooth bases with whole key decomposition;

Second goes on foot, and a plurality of teeth position of different directions all is set on the axial cross section of tooth base synchronously;

In the 3rd step, all open the through hole in same base footpath at the center of tooth base;

The 4th goes on foot, and the height of each tooth position all is set by unified altitude datum unit to the vertical distance of tooth top with the center of tooth base on the tooth position of different directions;

In the 5th step, on key handle, fixedly install nut;

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 the tooth base and each tooth position.

The present invention is based on the basic principle of modern process industry, standardization, seriation, standardization etc. are applied to the key manufacture process, founded the notion 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 seriesization, on this basis, picked at random tooth base is assembled into various keys, and the tooth base combine and assemble of no individual character is become personnalit key, has simplified the key manufacturing process widely.

1, tooth base

Referring to figure one, be a common common key, be whole shape.Referring to figure two, be the tooth base that the whole key among the figure one is resolved into.The main part of key is a tooth, and the height difference correspondence of these teeth the pellet shot from a slingshot 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 among the figure one has five teeth, just can resolve into five tooth bases among the figure two.Referring to figure three, be 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 is had on the same cross section of key.General flat key has only a direction that tooth is arranged, so have only a tooth position.Referring to the figure of a among the figure four, the cross key is in that tooth (being that four teeth are arranged on the same cross section) is arranged on the four direction, so four tooth positions are arranged.

3, tooth depth

Tooth depth be the tooth base key element two.Corresponding different pellet shot from a slingshot, 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 is meant, for the cross key, tooth depth is meant the vertical distance of the center line of key to 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 successively increase just changes a flute profile, 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 A, B, C, D, E can supply its selection for five kinds.Like this, with regard to the cross key, a tooth base has four tooth positions, the desirable five kinds of tooth depths in each tooth position, and the permutation and combination of these tooth positions, tooth depth has then 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 difference of each tooth base of same tooth position 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, have only when every toothrow shape when pellet shot from a slingshot in the corresponding lock core all coincide, 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

By the key of manual formula production, two locksets of the same model that same producer produces, same specification occur available same as the phenomenon of key unlocking sometimes at present, and obviously this is a potential safety hazard.This technology has been stopped this potential safety hazard.

If be made up of five tooth bases by each cross key, then 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 big numeral, comes combine and assemble lockset and key at random by this, and the combination that duplicates is impossible basically, two locksets just occur but phenomenon with identical key almost is impossible.Here it is produces key with this technology and greatly improves to the safety that lockset brings, and key is unique.

2, the password of key

This assembling 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 under the key cipher situation.Referring to figure six, specific practice is:

(1) aborning four tooth positions of each tooth base is 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 the given side among the figure six, second, fourth, third;

(3) this essence is exactly the tooth preface password of this key, has only the tooth preface 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) at ordinary times can be first loosen nut transfer disorderly above-mentioned mark order, tightening nuts again, at this moment the tooth preface of key is entanglement, can not unblank.Transfer again along password when needing to use, can unblank.

The key cipher that Here it is has only the assembling key just to have has brought the very big sense of security for key end user (particularly losing the children crowd of key easily).

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 standard component privately and come bitting steathily to unblank.In fact, this doubt is unnecessary.As previously mentioned, key is made up of five tooth bases, and each tooth base all chooses from 625 kinds of tooth bases at random, and it is right that just some tooth bases will guarantee to select, and just has 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.

Two, the another kind of unsafe sensation that may bring to the people: so, after anyone knows password from improper channel, can be easy to assemble privately key and unblank.In fact, this doubt also is unnecessary.As in like manner above-mentioned, even there is the people to know that first mark of password is a 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, has on each tooth base and is 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 also is an astronomical figure, therefrom only use password with the examination choosing, and also be 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 key simultaneously and password just can be unblanked, and the person is of no avail only to know the one.

(2) versatility of key

According to the notion of the principle of above-mentioned key cipher and shaped as key bit as can be known, any one assembling cross key, behind its tooth position of some tooth base rotations with regard to conversion profile of tooth, in fact just become another key.If prepare corresponding lockset aborning consciously, 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 technology to customize this key and lockset, just can accomplish a plurality of door locks totally one key, significantly 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) Pei Zhi convenience

This fabricated standard key is also given in key loss or is prepared new key again after damaging 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, then 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 precise machining process at present is ripe day by day, multiple no surplus process technologies such as the cold-drawn of the production technology employing new and high technology content of tooth base, cold forging, precision forging, this will greatly reduce material consumption and increase substantially production efficiency, realize industrial progress.

Key is the complementary products and the auxiliary products of lockset, and the industrial progress of key must drive the industrial progress of lockset.Because standardization, seriation, the standardization of tooth depth, the pellet shot from a slingshot size supporting with tooth depth also realizes standardization, seriation, standardization thereupon, and then be tapered end parts such as internal cylinder, outer lock core, its result will drive standardization, seriation, the standardization development that whole lockset is made.
