Abstract

The utility model relates to a key channel former, which comprises a base, a die cavity is formed at one end of the base and is sunk to form a buffer chamber and is provided with a diaphragm made of plastics, the appearance of the diaphragm is assorted with the die cavity and is removably clamped in the die cavity, and the diaphragm is fixed by a fixed cover. During application, a force is applied to push a parent key to penetrate the diaphragm and to leave a through hole with a section profile on the diaphragm, and then the key billet is compared with the through hole one by one to check whether the sections are matched, so as to save much selecting time and to avoid the harassment of wrong selection due to visual misjudgment.

Description

The key channel former

Technical field

The utility model is a kind of key channel former, refers in particular to a kind of mat key and runs through a plastic moulding matrix of fixing of tool and duplicate the former of its section with the key blank section of comparing.

Background technology

Key is a convenient and indispensable instrument in modern daily life, in every case be used to administer the door lock of discrepancy, the lock of the vehicles, antitheft storage with lock and device activation lock or the like countless latch fitting of all kinds, all need to utilize key operated.

And be common to now in the technology of making copy key between the locksmith, wherein an important first prosomite is must be between the key blank of different external forms of all kinds, pick out close with the mother key external form and base substrate that section is identical to duplicate the work of making, yet, the locksmith's is easy free-hand comparing mostly according to selecting mode in the prior art, by naked eyes mother key and key blank are contrasted, because the base substrate quantity of required contrast is often various, please referring to shown in Fig. 6-9, even the key blank 80 that length is similar to external form, also can have different section 81A separately, 81B, 81C, and because key blank 80

section

81A, 81B, the difference that the external form of 81C just rises and falls is not remarkable, must expend many spirit and time by the naked eyes step 1 of judging that compares, two come more likely to pick out section 81A because of naked eyes misjudgment slightly on selecting, 81B, the inconsistent base substrate 80 of 81C external form, and then create can't be the correctly corresponding copy key of opening lockset, with this, the prior art means of comparison key section are a not satisfactory mode.

The utility model content

Because aforesaid the deficiencies in the prior art point, the utility model designs a kind of key channel former, its mat key runs through a fixing plastic moulding matrix of tool, and the groove that duplicates corresponding its section on matrix is compared the key blank section to improve the convenience and the correctness of comparison.

For achieving the above object, the technological means that the utility model adopted is a kind of key channel former of design, and it comprises:

One base, it is that a block and an end are recessed on that to form a section be microscler die cavity, and on the die cavity from the surface the recessed surge chamber that forms;

One matrix, it is the made lamellar body of a tool plastic type material, the external form of matrix is matched with die cavity.

Further, the open section of surge chamber can be elongated, and base is provided with fixed part in this end, and this fixed part is looped end and forms screw thread on the side wall surface of this end;

Further, form mark on the matrix surface corresponding to surge chamber;

Further, also be provided with a fixed cap, it is the lid that the fixed part of base upper end is fixed in a covering, which is provided with the portion of wearing corresponding to surge chamber, it is the perforation that runs through moulding fixed cap wall, the wall of corresponding base is resisted against on the openend of die cavity on the fixed cap, forms screw thread also by this with fixed cap and base fixed engagement on the inwall anchor ring of the corresponding screw thread of fixed cap.

During use, the user only needs the matrix correspondence is arranged in the die cavity, again fixed cap is covered, and the portion of wearing certainly makes mother key run through matrix by knocking of the application of force or aid, and on this matrix, leave the groove of section external form, whether coincide to inspect by key blank correspondence one by one being attempted penetrating this perforation more afterwards, if the key blank that section coincide can be passed the section of this groove easily, can save many times of selecting with this, and can avoid selecting wrong puzzlement because of the erroneous judgement of naked eyes.

The specific embodiment

See also shown in Figure 1ly, key channel former of the present utility model includes a base 10, a matrix 20 and a fixed cap 30 in a preferred embodiment.

Please further cooperate referring to shown in Fig. 2-4, aforesaid base 10 is a block, the one end is recessed on and forms the die cavity 11 that a section is microscler fixedly usefulness, and form a surge chamber 12 from surperficial being recessed on its die cavity 11, the open section of surge chamber 12 can be elongated, this surge chamber 12 can provide a key 40 to be placed through wherein, and base 10 is provided with fixed part 13 in this end, and this fixed part 13 can be looped end and form screw thread 14 on the side wall surface of this end.

Aforesaid matrix 20 for material with plastic type (for example: lead) and wall thickness is thin is beneficial to the lamellar body that key 40 runs through, the external form of matrix 20 is matched with die cavity 11 and detachable or be fixed in the die cavity 11, the plastic mark 21 that has corresponding to surge chamber 12 on the surface of matrix 20, it can be the lines that carves in matrix 20 surfaces, make by this user can confirm surge chamber 12 the position and clearly with key 40 on correct position.

Aforesaid fixed cap 30 is the hollow lid that the fixed part 13 of base 10 is fixed in a covering, which is provided with the portion of wearing 31 corresponding to surge chamber 12, it can be and runs through the perforation that takes shape in fixed cap 30 walls, wearing portion 31 meets the external form of key 40 and makes key 40 portion 31 that can wear long from fixed cap 30 outsides penetrate by this, and run through matrix 20 and enter in the surge chamber 12, the wall of corresponding base 10 is resisted against on the openend surface of die cavity 11 on the fixed cap 30, and cooperate the internal face of die cavity 11 that matrix 20 clippings are positioned in the die cavity 11, moreover form screw thread 32 on the inwall anchor ring of fixed cap 30 corresponding screw threads 14 also by this with fixed cap 30 and base 10 fixed engagement.

Please further cooperate referring to shown in Figure 5, the utility model also can be done a different design with the groove cave 11A on the base 10A and surge chamber 12A and corresponding to the former matrix 20A on external form in another embodiment, for example be circular with matrix 20A exterior design, when having the key 40 of different section external form, can replace with suitable former and use for this key 40 to provide the utility model to be implemented on.

And when using, the user only needs matrix 20, the 20A correspondence is arranged in die cavity 11, in the 11A, again with fixed cap 30 airtight covering, and mother key 40 is worn in the portion 31 certainly corresponding to matrix 20, behind the tram on the 20A, by knocking of the application of force or aid to make mother key 40 run through

matrix

20,20A, the mother key 40 that runs through can be in this matrix 20, leave the groove identical on the 20A with its section external form, then again by with key 40 base substrates one by one to should groove, and by could correspondence penetrating wherein whether be fit to mother key 40 to inspect section, if key 40 base substrates that section coincide just can pass the section of this perforation easily, can save many times of selecting cost with this, and can avoid selecting wrong puzzlement because of the erroneous judgement of naked eyes.
