Description

Lock core and key

Technical field

The utility model relates to a kind of lockset, particularly a kind of lock core and the key supporting with it.

Background technology

At present, lockset mainly contains two big classes, and a class is a coded lock, and another kind of is mechanical lock.The advantage person of being to use of coded lock need not to wear key, only need pre-set password is remembered to get final product, this lock generally is used for the occasion of comparison privacy, generally have only people of user to use, generally be not suitable for family's mode of occupation such as door lock, limited its scope of application to a certain extent.And if the mechanical lock user is key loss, other people just might open its lockset so, make the user relieved inadequately, in addition, if do not have standby key then lockset can only be destroyed, bring loss to the user.

The utility model content

The purpose of this utility model is, a kind of novel lock core and supporting key are provided, even the lockset key loss that they are formed does not lose its safety yet, in addition, its key can use common key, need not to worry not have standby key.

Technical problem to be solved in the utility model is achieved by the following technical solution: a kind of lock core and key, lock core comprises the upper lock core cap, lock stem stem and following lock core, this upper lock core cap is fixedlyed connected with the stem stem of locking, the stem stem of locking is positioned at the soffit of upper lock core cap, the upper lock core cap can embed down in the lock core, and there is the hole of keeping supplying the lock core cap and locking the stem stem insertion at following lock core center; The surface of upper lock core cap has a plurality of open holes of going up, and the correspondence position of following lock core also has the following open hole of equal number, and unlatching is housed in the last open hole, in the following open hole unlatching is housed down, and each bottom of opening down is connected with following lock core by spring; In the upper lock core column bottom hole that is connected with latch fitting is arranged, the stem stem of locking rotates can open latch fitting and closed latch fitting; The length difference of opening on each, but the length of each is same all less than upper lock core cap thickness T 1, each length of opening down is also different, but the length of each is all less than the thickness T 2 of lock core down; The unlatching of a key quantity is no less than the quantity of opening, and the cross sectional shape of key operated head is the T font, and the T font bottom lengths of each key is also inequality.

T font bottom lengths of having only each key operated head with and it is corresponding when going up the length sum of opening and equaling upper lock core cap thickness T 1, lock stem stem and upper lock core cap just can relative under lock core rotate.

Lock core of the present utility model has a plurality of going up to open and open down, and key has and is no less than the unlatching head of opening quantity, having only on each the enable possition all is with correct specific unlatching head upper lock core cap and last core lock are rotated to open lockset, therefore, even key loss, if other people do not know that specific slotting key operated head order also can't open lockset at all, just because of this reason, this key can be made the unified specification market and sell, if user's key loss as long as buy back the key of same specification, and needn't worry that other people can use this key unlocking, more do not need to unblank by force, cause damage.

The specific embodiment

Referring to Fig. 1-Fig. 3, a kind of lock core and key, lock core comprises upper lock core cap 1, lock stem stem 2 and following lock core 3, this upper lock core cap 1 is fixedlyed connected with the stem stem 2 of locking, certainly both also can be one-body molded, the stem stem 2 of locking is positioned at the soffit of upper lock core cap 1, and upper lock core cap 1 can embed down in the lock core 3, and there is the hole of keeping supplying lock core cap 1 and locking stem stem 2 insertions at following lock core 3 centers; The surface of upper lock core cap 1 has 8 and goes up open hole 11, and the correspondence position of following lock core also has 8 following open holes, is equipped with in the last open hole 11 and opens 4, is equipped with down in the following open hole 31 and opens 5, and each is connected with following lock core 3 by spring 6 bottom of unlatching 5 down; Elastic force by spring 6 compresses unlatching 5 and last unlatching 4; In stem stem 2 bottoms of locking the hole 21 that is connected with latch fitting (figure does not show) is arranged, the stem stem 2 of locking rotates can open latch fitting and closed latch fitting; Open 4 length difference on each, but the length of each is same all less than upper lock core cap thickness T 1, it is also different that each opens 5 length down, but the length of each is all less than the thickness T 2 of lock core 3 down; The unlatching of key 7 quantity are no less than the quantity of unlatching 4, that is to say, be no less than 8 in the present embodiment, obviously, key operated 7 quantity is many more, it is big more that choosing is opened a difficulty of 7 to each, and key operated 7 cross sectional shape is the T font, and each T font bottom lengths of key operated 7 is also inequality.T font bottom lengths of having only each key operated head with and its corresponding going up open length sum of 4 when equaling upper lock core cap 1 thickness T 1, lock stem stem 2 and upper lock core cap 1 just can relative under lock core 3 rotate.If selected key operated 7 length is too small, then following 5 distances that descend of opening are too little, rotate relative to following lock core 3 with upper lock core cap 1 just hindered the stem stem 2 of locking.On the contrary, if selected key operated 7 length is excessive, it is too big then to open down 5 distances that descend, just on open 4 and inserted in time open hole 31, hindered lock stem stem 2 and upper lock core cap 1 equally and rotated relative to lock core 3 down, lockset is the same can not be opened.In addition, the handle 12 that makes its rotation is arranged on upper lock core cap 1.

In the foregoing description, the last quantity of opening and opening down is 8, can certainly select 2,3 or more for use, and obviously, quantity many unlatchings difficulty more is just big more.As long as the quantity of same key operated head is not less than the quantity of unlatching 4, in the foregoing description, can select for use to open on the different length to be M, the upper lock core cap is laid and opened is N, but open method just has M ^NKind, used mathematical ranking method here, for example M is 10, can certainly be 9 or 11,12, but just selects 10 for use for convenience of calculation; N is 8, and open method is exactly 10 so ⁸Kind.As a same reason, N is 12, and open method is exactly 10 ¹²Kind.Should there be key to open in theory by this lock core.

In order to implement with easy to use, last unlatching with open head and all compile respectively and be 0-9 by different length, ten numbers altogether, and go up and open and open each identical numbering length sum of head bottom and all equal upper lock core cap length.The upward unlatching number that for example is installed in the upper lock core cap clockwise is 25251314, and using during unlatching and opening No.1 sign indicating number is 25251314, and by inserting clockwise, rotating handles is locked and just can have been opened.

In addition, being uneven in length of unlatching 4 is not to have nothing in common with each other on each, just produces 100,000,000 kinds of different unlatching methods but set gradually 89 (99999999) maximum numbers by ranking method (install 8 as the upper lock core cap and go up unlatching) by 80 (00000000) minimum numbers.Certainly, this is to be provided with in theory, can be provided with according to qualifications in the actual production.The following unlatching of different length is as long as be provided with at random.

At last, the unlatching head of key can be made distributedly in the utility model, also can make modularly, and distributed needs remember that each opens the correspondence position of head.But easy to use for some old man, can make modularly, as long as a corresponding basic point is arranged,, can open by key just being inserted this basic point.

The utility model also has some other distortion or improvement.If those skilled in the art are subjected to the change or the improvement of the conspicuous unsubstantiality that inspiration of the present utility model makes, all belong to the protection domain of the utility model claims.
