In order to solve the problem of it is in the prior art need to carry it is more key unlocking is inconvenient to carry and difficult management,
The present invention provides a kind of lock cylinder system, key system and lock systems.
A kind of lock cylinder system as shown in Fig. 1 to Figure 34, including multiple lock cores 10, lock core 10 have locking blade 11, close
Locking blade 11 has hierarchical structure 111, and is latched the solution that blade 11 has the latched position reconciliation lock pin 10 of locking lock core 10
All locking blades 11 of lock position, all lock cores 10 include the grade blades such as at least one height and at least one low grade blade,
And 111 size of hierarchical structure of high grade blade and the hierarchical structure 111 of low grade blade is of different sizes, has high-grade leaf
Piece and do not have low grade blade lock core 10 be high-grade lock core, the high grade blade of at least one of high-grade lock core is replaced
It is changed to the lock core 10 that low grade blade obtains, is inferior grade lock core corresponding with high-grade lock core；When corresponding with high-grade lock core
High-grade key when unlocking high-grade lock core or inferior grade lock core, the solution lock-bit 21 of high-grade key is able to drive high-grade lock
All locking blades 11 movement in core or inferior grade lock core, and all locking blades 11 is made to switch to solution lock-bit by latched position
It sets, lock core 10 unlocks；When inferior grade key corresponding with inferior grade lock core unlocks inferior grade lock core, the unlock of inferior grade key
Position 21 is able to drive the movement of all locking blades 11 in inferior grade lock core, and all locking blades 11 is made to move to solution lock-bit
It sets, the unlock of inferior grade lock core；When inferior grade key corresponding with inferior grade lock core unlocks high-grade lock core, inferior grade key
Solution lock-bit 21 is only able to drive the locking blade 11 of the part in high-grade lock core and moves, and part is latched blade 11 and is maintained at locking bit
It sets, high-grade lock core keeps locking.
The present embodiment in lock core 10 by being provided with hierarchical structure 111 of different sizes, and according to hierarchical structure 111
Size relation will be latched blade 11 and divide for high grade blade and low grade blade, further according to the locking leaf installed in lock core 10
The grade lock core of piece 11 is divided into high-grade lock core and inferior grade lock core, wherein high-grade lock core only includes high grade blade, and low
Grade lock core must include low grade blade.In this way, when the high-grade key in key system is inserted into high-grade lock core, it is high
The solution lock-bit 21 of grade on the key can drive all locking blades 11 in high-grade lock core to move to unlocked position, thus will
High-grade lock core unlock；When the high-grade key in key system is inserted into inferior grade lock core, high-grade solution on the key
Lock-bit 21 can drive all locking blades 11 in inferior grade lock core to move to unlocked position, thus by inferior grade lock core solution
Lock；When the inferior grade key in key system is inserted into high-grade lock core, the solution lock-bit 21 of inferior grade on the key can only be driven
The part locking blade 11 moved in high-grade lock core moves to unlocked position, there remains locking blade 11 and stills remain in locking bit
It sets, thus high-grade lock core keeps locking；When the inferior grade key in key system is inserted into inferior grade lock core, the situation with
High-grade key is inserted into identical in high-grade lock core, and inferior grade key unlocks inferior grade lock core, specifically repeats no more.It is above-mentioned
For set-up mode under the premise of keeping lock core 10 to be classified, high-grade lock core and inferior grade lock can be unlocked by realizing high-grade key
Core, while inferior grade key can not unlock the purpose of high-grade lock core, to facilitate the unlock of lock core 10, greatly improve
The unlock efficiency of lock core 10.
It needs to illustrate the following herein:
First, in high-grade lock core and inferior grade lock core in all locking blades 11, elementary a kind of locking leaf
Piece 11 is low grade blade, and what grade was higher than low grade blade is high grade blade, that is to say, that only may be used in low grade blade
It can be a grade, and may simultaneously include that the grade of multiple grades and each high grade blade is intended in high grade blade
Higher than the grade of low grade blade.
Second, there is corresponding relationship between above-mentioned high-grade lock core and inferior grade lock core, inferior grade lock core be
On the basis of high-grade lock core, the grade blades such as wherein at least one height are replaced with what low grade blade obtained, only this
In the case of, it can guarantee that high-grade key can unlock inferior grade lock core, without between two lock cores 10 of corresponding relationship
It cannot achieve unlock.And the possible more than one of inferior grade lock core corresponding with high-grade lock core according to the actual situation can
There can be multiple inferior grade lock cores that there is corresponding relationship with one or several high-grade lock cores simultaneously, high-grade key can only unlock
Inferior grade lock core with corresponding relationship.When high-grade key is inserted into non-corresponding lock core, high-grade solution lock-bit on the key
21 mismatch with the locking blade 11 in non-corresponding lock core, and high-grade key can not drive all locking leaves in non-corresponding lock core
Piece 11 moves to unlocked position, also can not just unlock the inferior grade lock core of non-corresponding.
By grade classification, lock cylinder system includes level-one lock core, second level lock core, the three-level lock core ... that grade is divided from high to low,
Correspondingly, locking blade 11 includes a grade blade 1101, two grade blades 1102, three grade blades 1103 ... of grade from high to low.
For clear explanation, spy is such as given a definition: in lock core 10, the direction of lock core 10 is inserted into along key 20, according to each locking leaf
The grade of piece 11 is different, the grade of each locking blade 11 is successively write to the form to form " XXX " from left to right, for example, secondary latch
There are three blade 11 is latched in core, three grade blades 1103, two grade blades are followed successively by according to the direction that key 20 is inserted into lock core 10
1102, a grade blade 1101 then writes " 321 ".
The present embodiment is using high-grade lock core as second level lock core, and inferior grade lock core is is illustrated for three-level lock core, accordingly
Ground, low grade blade are three grade blades 1103, and high grade blade is a grade blade 1101 and/or two grade blades 1102.
In the present embodiment, low in two locking blades 11 of high-grade lock core and inferior grade lock core corresponding position
Grade of the grade of the locking blade 11 of grade lock core not higher than the locking blade 11 of high-grade lock core.Specifically, according to key
Spoon 20 is inserted into the direction of lock core 10, and each blade 11 that is latched successively is defined as first, second, third ..., similarly, locks in inferior grade
In core, the direction that lock core 10 is also inserted into according to key 20 is defined as first, second, third for blade 11 is latched ..., then defines name
Identical two lockings blade 11 is then referred to as the locking blade 11 of corresponding position between two lock cores 10, the two locking blades
Need to meet the grade that is latched blade 11 of the grade not higher than high-grade lock core of the locking blade 11 of inferior grade lock core between 11.
Certainly, above-mentioned definition is merely to unlock corresponding position and the definition that carries out, and the mode defined is also only a kind of citing,
It can be defined in other ways.
In a lock core 10, locking blade 11 may only have one, such as " 1 ", and in more situations, it is latched blade 11
It would generally be provided with multiple, since low grade blade only has one kind, thus it is quantity superposition, such as " 333 ", but due to
High grade blade may include multiple grades locking blade 11, thus when high grade blade be it is multiple when, can be divided into
Lower two kinds of situations: first is that it is identical with the grade of all high grade blades in inferior grade lock core in high-grade lock core, that is, it is one
Grade blade 1101 or two grade blades 1102, such as " 222 ", " 223 " etc；Second is that in high-grade lock core and inferior grade lock core
In, the grade of grade blades such as the grades of the grade blades such as at least one height and other height is different, i.e., high grade blade includes one simultaneously
Grade blade 1101 and two grade blades 1102, such as " 123 " etc, and in a lock cylinder system, above-mentioned two situations have can
One kind can only occur, it is also possible to which two kinds occur simultaneously.
Due to the possible more than one of inferior grade lock core corresponding with high-grade lock core, thus in all lock cores 10, grade
Identical lock core 10 can be divided into following two situation: first is that the lock core 10 of ad eundem only has one, such as an only second level
Lock core；Second is that the lock core 10 of at least one ad eundem have it is multiple, between the lock core 10 of ad eundem, be latched blade 11 arrangement side
Formula is not identical, that is, the setting position of two grade blades 1102 is different, for example, there are two second level lock core, the two second level lock cores
Locking blade 11 be respectively " 211 " and " 121 ", the two second level lock cores are referred to as the first second level lock core and the second secondary latch
Core, the three-level lock core that replacement locking blade 11 obtains on the basis of the first second level lock core is exactly corresponding with the first second level lock core
First three-level lock core, similarly, on the basis of the second second level lock core the obtained three-level lock core of replacement locking blade 11 be exactly with
The corresponding second three-level lock core of second second level lock core, the first secondary key being correspondingly arranged with the first second level lock core can unlock
One second level lock core and the first three-level lock core, but the second second level lock core and the second three-level lock core can not be unlocked, with the second secondary latch
The second secondary key and above situation that core is correspondingly arranged are similar.
And when the lock core of ad eundem 10 has multiple, between the lock core 10 of ad eundem, high grade blade and low grade blade
Quantity difference is identical, arrangement mode is different, i.e., above-mentioned " 211 " and " 121 ".Certainly, high grade blade and the inferior grade number of blade
Amount may not also be identical, such as " 112 " and " 122 " the two lock cores 10 are second level lock core, one grade blade 1101 and second level
The quantity of blade 1102 is different, and arrangement mode is also different.
The example above have not been changed locking blade 11 total quantity, be only it is different grades of locking blade 11 accounting not
Together.And corresponding inferior grade lock core is obtained the high grade blade of at least one of high-grade lock core is replaced with low grade blade
On the basis of, the mode being changed to the quantity of locking blade 11 can also be increased, for example, second level lock core " 212 ", most by it
Two grade blades 1102 in left side replace with three grade blades 1103, then remove two grade blades 1102 of the rightmost side to obtain three-level lock
Core " 31 " then also has corresponding relationship between three-level lock core " 31 " and second level lock core " 212 ", also can be realized the classification pipe of lock core 10
Reason.It should be noted that when the quantity to locking blade 11 is changed, it is ensured that be latched blade 11 in high-grade lock core
Quantity is no less than the quantity that blade 11 is latched in inferior grade lock core, such as the scheme of second level lock core " 122 ", three-level lock core " 1232 "
It is unsatisfactory for above-mentioned condition, cannot achieve the differentiated control of lock core 10.
As shown in Fig. 1, Fig. 8 and Fig. 9, lock core 10 includes shell 12 and core 13, and core 13 is rotatably arranged in shell
