Specific embodiment
The present invention using anti-theft cipher device carry out it is antitheft be advantageous in that, anti-theft cipher device use with flux density code compiles
Five heavy antitheft modes based on code is antitheft, five, which weigh any one in antitheft modes, fails on corresponding with key, then door can not be beaten
It opens, to considerably increase anti-theft effect, while the permutation and combination type in five weight antitheft modes is more, user can be by changing
The permutation and combination for becoming any one in five weight antitheft modes of anti-theft cipher device can make former key fail, and replace antitheft
The permutation and combination process of code device is relatively simple, in addition to this, due to being encoded to the level Four burglar-proof mechanism of principle with flux density code
In the magnetism of four/pellet of pellet five cannot observe by the naked eye and obtain, so that greatly strengthening criminal replicates key
Difficulty, and enhance the anti-theft performance of this lock core.
The anti-theft lock of high protection level, including lock core, the key 100 to match with lock core, lock core includes being installed on door
Plug body 200 in body keyhole is set in plug body 200 and matches with key 100 and using five heavy antitheft squares
The anti-theft cipher device 300 of formula is provided with moving part, 200 struck side of plug body between 200 struck side of plug body and lock tongue
It rotates and lock tongue insertion/disengaging can be driven to be set to the dead bolt hole on doorframe by moving part.
The motion state of the plug body 200 can be divided into that driving lock tongue is inserted into dead bolt hole and door is pent anti-
Robber's state, driving lock tongue are detached from the open state that dead bolt hole and door are opened, and the key 100 is inserted into plug body 200
It is interior and draw that plug body 200 switches to the rotation of open state to rotate forward, key 100 is inserted into plug body 200 and leads
Draw plug body 200 and switches to the rotation of anti-theft state as reversion.
After the correspondence of key 100 is inserted into plug body 200 by user, if key 100 is the key to match with lock core
Spoon, then while key 100 is inserted into plug body 200, key 100 is locked and can be rotated, otherwise key 100 can not turn
It is dynamic；
User, which rotates forward key 100 after the correspondence of key 100 is inserted into plug body 200, can be such that plug body 200 switches
To open state, lock tongue is detached from dead bolt hole, i.e. door is opened, when subsequent user inverts key 100 to initial position, lock core
The locking to key 100 is cancelled, key 100 can be transferred to, and during key 100 is transferred to, lock tongue is stationary；
Reversion key 100 can be such that plug body 200 switches after the correspondence of key 100 is inserted into plug body 200 by user
To anti-theft state, lock tongue is inserted into dead bolt hole, i.e., door is closed by locked, and subsequent user rotates forward key 100 to initial position
When place, lock core cancels the locking to key 100, and key 100 can be transferred to, and during key 100 is transferred to, lock tongue is stationary；
Key 100 makes 200 switching state of plug body and door is made to be opened/lock closing and the process transferred to of key 100
In, 200 struck side of plug body is opposed by moving part traction lock tongue and answers motion change, which is the prior art, herein
It repeats no more.
The key 100 includes female key 110, sub- key 120, and sub- 120 coaxial sleeve of key is set in female key 110, sub- key 120 with
It is additionally provided between female key 110 for controlling determinant key 120 whether can be by the ejecting mechanism 130 that pops up in female key 110.
Female key 110 includes female key body 111, and female key body 111 is circular tube structure open at one end, closed at one end
And the closed end Matching installation of female key body 111 has the shank of the key 112, the bottom of chamber of female key body 111 is coaxially arranged with guide rod 113.
