Inside be equipped with one piece of transverse slat 7-3-1, inside equipped with transverse slat 7-3-1 three lower clamping block 7-3 top surface be equipped with third locking bar
One piece of transverse slat 7-3-1 in slot 7-3-2, three pieces of transverse slat 7-3-1 is equipped with third and unlocks slot, and third unlocks the inside of slot
Equipped with unlock platen 7-3-4, the bottom end of the unlock platen 7-3-4 is welded to connect compressed spring 7-3-5, compressed spring 7-3-5
Lower end be fixedly connected on the bottom surface of lower clamping block 7-3.When in use, sliding locking bar 2 needs the third locked component 7 first
Judge the inside for being inserted into third locking bar slot 7-3-2, is inserted into the transverse slat 7-3-1 third unlock slot being equipped with
Inside can just unlock, solve at this point, also needing firmly to push the lower end that will be unlocked platen 7-3-4 and be depressed into inside lower clamping block 7-3
The interference of false judgment is more when lock, so that it is larger to crack difficulty.
The lower end of the third unlock slot is fixedly connected with limit sliding cylinder 7-3-3, and the limit sliding cylinder 7-3-3's is interior
Diameter is identical as the unlock outer diameter of platen 7-3-4；The inside of limit sliding cylinder 7-3-3 is arranged in the compressed spring 7-3-5.
The lower slider lock frame 7-1, middle slide lock frame 6-1 are identical with the structure of upper slide lock frame 5-3, and lower slider locks frame 7-
1, the both ends of the top surface of middle slide lock frame 6-1 and upper slide lock frame 5-3 are all equipped with spacing projection.
The quantity of the upper clamping block 5-2, middle clamping block 6-3 and lower clamping block 7-3 are all no less than five.
Safe coded lock of the invention, its working principle is that: when in use, by sliding locking bar 2 out of password lock body 1
Portion skids off, and sliding locking bar 2 is inserted on the lock of locking locking equipment, when needing to unlock, needs to be accurately aimed at password lock body 1
The corresponding unlock slot of internal the first locked component 5, the second locked component 6 and third locked component 7, anti-theft performance compared with
By force；First locked component 5 is carrying out in use, sliding locking bar 2 is firstly the need of being inserted into the first of the top surface upper clamping block 5-2
The inside of locking bar slot 5-2-1 is then passed through the inside that the first unlock slot 5-2-2 enters to the second locked component 6；Described second
When in use, sliding locking bar 2 passes through the inside that the first unlock slot 5-2-2 enters to the second locked component 6 to locked component 6, needs
The inside that the second locking bar slot 6-3-1 enters to middle clamping block 6-3 is first passed through, top surface is equipped with the second locking bar slot 6-3-1's
There are two middle clamping block 6-3 is set, locked in one that top surface is equipped in two middle clamping block 6-3 of the second locking bar slot 6-3-1
The bottom surface of block 6-3 is equipped with the second unlock slot 6-3-2, therefore, when sliding locking bar 2 across the second locking bar slot 6-3-1,
The accuracy of unlock improves unlock difficulty also wait judge, only sliding locking bar 2 correctly pass through the second locking bar slot 6-3-1 and
The inside that second unlock slot 6-3-2 can just enter to third locked component 7 carries out unlock judgement in next step；The third locking
When in use, sliding locking bar 2 is inserted into the inside of third locking bar slot 7-3-2 firstly the need of judgement to component 7, is inserted into cross
Unlock platen 7-3-4 is depressed into lower locking at this point, also needing firmly to push by the inside for the third unlock slot that plate 7-3-1 is equipped with
Lower end inside block 7-3 can just unlock, and the interference of false judgment is more when unlocking, so that it is larger to crack difficulty；It is close in progress
It, need to be by integral demounting, by the sequence of multiple upper clamping block 5-2 inside mounting groove 5-1 upper in upper slide lock frame 5-3 when code modification
It resets, and again through screw-driving, by multiple middle clamping block 6-3 inside middle mounting groove 6-2 in middle slide lock frame 6-1
Sequence reset, and again through screw-driving, lower slider is locked into multiple lower locks in frame 7-1 inside lower mounting groove 7-2
Determine block 7-3；Sequence reset, and again through screw-driving, to carry out the modification of password.
Certainly, above description is not limitation of the present invention, and the present invention is also not limited to the example above, the art
