The primary and secondary theftproof lock of a kind of flux density code unlock comprising plug body 100 and match with plug body 100
Key body 200, plug body 100 include being in the form of a column both ends open and fixed and arranged outer lock core cylinder 120, coaxial arrangement in outer
The first internal cylinder cylinder 130 and the second internal cylinder cylinder 140 in lock core cylinder 120, the first internal cylinder cylinder 130 and second
Internal cylinder cylinder 140 is the ring body structurc of both ends open, and wherein one end is outer end to outer lock core cylinder 120, the other end is inner end,
First internal cylinder cylinder 130 is arranged close to its outer end, the second internal cylinder cylinder 140 is arranged close to its inner end, the first internal cylinder cylinder
It is provided with the pellet for constraining rotation between body 130 and outer lock core cylinder 120 and collectively constitutes female lock, the second internal cylinder cylinder
It is provided with the position-limit mechanism for constraining rotation between body 140 and outer lock core cylinder 120 and collectively constitutes sub- lock, the key
Spoon ontology 200 includes handle 210 and the matched mother key 220 of female locking phase and the matched sub- key 230 of sub- locking phase and setting
Confining part 240 between mother key 220 and sub- key 230,220 coaxial sleeve of mother key are set to the outside of sub- key 230, son
Key 230 is arranged to the retracted mode that can mutually switch with stretching state and original state confining part 240 is constrained to
Retracted mode.
Pellet between mother key 220 and female lock is protruding to the length that in the first internal cylinder cylinder 130 and homology functor does not protrude
Spend different, mother key 220 includes the female key cylinder that is fixedly connected of sun handle 210, is offered on the periphery of female key cylinder and pellet
The zigzag protrusion to match, cooperation unlock is same as the prior art between mother key 220 and female lock, repeats no more.
Second internal cylinder cylinder 140 is connected with the plectrum 150 for driving lock tongue, and mother key 220 and female locking phase are mutual
Cooperation rotation makes sub- key 230 switch to stretching state for triggering, and stretches out the sub- key 230 of state for releasing the second internal lock
The rotational restraint of position-limit mechanism between core cylinder 140 and outer lock core cylinder 120.
In use process, mother key 220 is inserted into the first internal cylinder cylinder 130 by user first, sawtooth on female key cylinder
The pellet of protrusion is pushed back and is completely disposed in 130/ outer lock core cylinder 120 of the first internal cylinder cylinder by shape protrusion, at this point, pellet
It releases to the rotational restraint between the first internal cylinder cylinder 130 and outer lock core cylinder 120, user's rotational handle 210, the first internal lock
Core cylinder 130 rotates synchronously and confining part 240 is made to release the constraint to sub- key 230, and sub- key 230 is cut by retracted mode
Shift to stretching state and be inserted into the second internal cylinder cylinder 140, sub- key 230 by magnetic force it is attracting/repelling each other makes position restrainer
Structure releases the constraint between external lock core cylinder 120 and the second internal cylinder cylinder 140, further rotational handle 210, the second internal lock
Core cylinder 140 rotates and plectrum 150 is driven to rotate synchronously, and plectrum 150 makes lock tongue bounce back and take off with doorframe by moving part
From.
Specifically, for the ease of mother's lock and son lock are protected and installed, the outer cover of the outer lock core cylinder 120
Equipped with shell 110, shell 110 and door-plate are detachably connected cooperation.
When mother key 220 is inserted into rotation in female lock, need that confining part 240 is made to release 220 pairs of sub- keys of mother key
230 constraint, sub- key 230 switch to stretching state by retracted mode automatically, for this purpose, the sub- key 230 includes and mother
Key cylinder axially constitutes the sub- key column of slide-and-guide cooperation along it, sub- key column stretch out female key cylinder length and sub- key column diameter with
Second internal cylinder cylinder 140 matches, and sub- key column coaxially offers set access slot 231 close to 210 one end of handle, covers 231 edge of access slot
The medium position in its groove depth direction coaxially offers built-in step 2 232, and built-in step 2 232 is extended through to handle 210, interior
The diameter for setting step 2 232 is greater than the diameter of set access slot 231, covers in access slot 231 and is provided with the guide rod being fixedly connected with handle 210
211, sub- key column and guide rod 211 axially constitute slide-and-guide cooperation along it, in order to enable sub- key column auto-extending mother's key cylinder
Outside, the external activity of the guide rod 211 are arranged with percussion spring 233, and percussion 233 one end of spring is supported with built-in step 2 232
Touching, the other end and handle 210, which contradict and fire the elastic force of spring 233, is directed toward built-in step 2 232 by handle 210 always, leads to
The elastic force effect for crossing percussion spring 233 makes sub- key column so that sub- key 230 is switched to stretching shape towards the slide outside of female key cylinder
State.
Specifically, the sub- key column is arranged close to 210 one end of handle in order to avoid falling off between sub- key column and female key cylinder
There are external step 234a, female key cylinder that 210 one end of handle is provided with the built-in step three to match with external step 234a
The stroke that 234b, external step 234a and built-in three 234b of step cooperate for constraining the female key cylinder sliding in sub- key edge,
Meaning is, avoids falling off between sub- key column and female key cylinder.
Under original state, need to guarantee that sub- key 230 is in retracted mode, in order to overcome the elastic force of percussion spring 233 to make
With sub- key column is located inside female key cylinder, the confining part 240 is set between sub- key column and female key cylinder and close to hand
Handle 210 arranges that confining part 240 includes the mounting groove 241 being opened on sub- key column periphery, and there are two the settings of mounting groove 241
And along the axially symmetric disposition of sub- key column, being provided at the notch of mounting groove 241 can be along the constraint block of sub- key column radial floating
242, be provided with restricted spring in mounting groove 241, restricted spring one end is fixedly connected with the slot bottom of mounting groove 241, the other end with
Constraint block 242 is fixedly connected, and the constrained port 243 to match with constraint block 242, original state are offered on the periphery of female key cylinder
Under, constraint block 242 is inserted into constrained port 243.
When mother key 220, which is inserted into, to be rotated in the first internal cylinder cylinder 130, need that constraint block 242 is made to overcome constraint bullet
It moves under the elastic force effect of spring towards the slot bottom of mounting groove 241 and is separated with constrained port 243, for this purpose, the outer lock core cylinder
The outer end of body 120 is coaxially arranged with annular convex platform 121, and boss 121 coaxially offers inner groove away from 120 one end of outer lock core cylinder
122, the slot bottom of inner groove 122 offers guide groove 123, and guide groove 123 includes the triggering section and changeover portion that head and the tail are connected, the touching
Hair the distance between section and 120 central axes of outer lock core cylinder are rotated in the clockwise direction and are gradually reduced, the changeover portion be arranged to and
The head of the coaxially arranged arcuate structure of outer lock core cylinder 120 and the changeover portion connects with the tail portion of triggering section along clockwise direction
Logical, the setting of guide groove 123 constitutes central symmetry there are two and along the central axes of outer lock core cylinder 120.
