Description
Technical field
The invention belongs to the combination disk technical field of mechanical type digital lock, it is related to the password that a kind of excircle does not set locking trough
Disk.
Background technique
The locking trough of most of mechanical digital disk is arranged on digital disk excircle in the prior art, this design scheme
Existing defect is also that clearly, the outer rim of digital disk is arranged in since the limitation of processing technology leads to different stage in locking trough
Exist between combination disk compared with big gap, can directly be inserted a probe into using gap and accurately determine positioning unlocking position, implement skill
Art unlock, thus greatly reduce password security performance；Followed by inner disc（I.e. combination disk signified in this patent is interior
Disk）It is all made of " O " type spring to be fixed in the circle center hole of external disk, since " O " type spring is elastic element, make in long-term
It can be decreased with its elastic property in the process, therefore it also decreases the fastening ability of inner disc, this may can make
" O " type spring can be rotated as inner disc rotates in decoding process, may seriously will affect the password positioning as combination disk
The performance of pin, in some instances it may even be possible to its loss of function can be made（" O " type spring notch deviates positioning pin position and may stop to determine
Position pin is engaged to influence positioning function with positioning tooth on inner disc）；Finally be adjust code during conventional digital lock between because sliding
The diameter difference that shifting block rotation generates can be superimposed, its error may be the several times of standard error when reaching afterbody, influence to adjust
The precision of code, and the sliding shifting block being driven is generally existing because design structure leads to intensity and the too low phenomenon of positioning accuracy,
Be easy because attacker exert oneself it is excessive due to cause slide shifting block damage phenomena such as.
Summary of the invention
Technical problems based on background technology, the invention proposes a kind of simple and reasonable, it is small to stir error, dials
A kind of big excircle of dynamic device intensity does not set the combination disk of locking trough.
Object of the invention can be realized by the following technical scheme：A kind of excircle does not set the combination disk of locking trough, packet
External disk and inner disc are included, the external disk and inner disc are the disk-shaped structure equipped with circle center hole；The external disk includes the first disk body and the
Two disk bodies, wherein first disk body is the shallow tubular structure of end face opening, the bottom surface of tubular structure, institute is arranged in circle center hole
It states the second disk body to be arranged in the first disk body by the way that fastening bolt is concentric, in the circle center hole of first disk body and the second disk body
It is respectively provided with a circle inner disc locating shoulder on the one of end face of circumference, forms the inner disc room of annular groove-shaped, first disk body
A cricoid ring lock clamp blind slot is formed between the shallow barrel of tubular structure and the excircle of the second disk body, outside the second disk body
The angle line set on circumference is equipped with a lock card blind slot, and the angle line set on second disk body is equipped with a positioning
Tank.
It is further used as preferably, the circumference set on one end face of the inner disc is equipped with fixed shifting block, another end
The inner circumferential side in face is equipped with annular shoulder, and the sliding shifting block on the circumference set on the annular shoulder equipped with arc is sliding
Slot, the sliding shifting block sliding slot is interior to be equipped with sliding shifting block, and the sliding shifting block is to match with the sliding shifting block sliding slot of arc
Arcuate structure, and shifting block is equipped on the outside of shifting block on the middle position of cambered surface sliding, in the sliding shifting block sliding slot excircle
Between be equipped with notch formed shifting block limited bayonet.
It is further used as preferably, positioning is provided with by pin shaft and the handover of locator retaining spring in the locator slot
Device, wherein described locator one end is equipped with positioning chuck, the other end is U-typed structure and is equipped with friendship in the end of U-typed structure
Fixation hole is connect, wherein being provided with locator retaining spring groove on the locator of the side opposite with positioning chuck.
It is further used as preferably, the positioning chuck is directed toward the center of circle side of disk body under the action of locator retaining spring
To.
It is further used as preferably, the radius of circumference is less than the circle center hole of external disk where on the outside of the fixation shifting block on the inner disc
The radius of interior inner disc locating shoulder, length of the fixed shifting block far from inner disc disk are 2 times of inner disc locating shoulder thickness.
It is further used as preferably, the external disk on the inside of locator slot is equipped with penetrating tune code bar jack.
Compared with prior art, device provided by the invention has the following advantages that：
1, the excircle of this password institute external disk does not give up locking trough, but the lock card head blind slot cooperation lock card for using end face concealed is blind
Slot effectively avoids stealing the drawbacks of this easily finds unlocking position using probe to which unlocking position is hidden setting；
2, the inner disc of this coded lock（The core disk of the coding for practitioner's meaning of going together）Fixed form is formed using external disk shoulder
Annular groove-shaped inner disc room, more traditional use " O " type spring is fixed to have significant advantage, and such as traditional " O " type spring is fixed
It can be with using time spring to weaken, " O " type spring may be subjected to displacement with the rotation of inner disc, may be stopped
Encode positioning port state；
3, using slidingtype shifting block, it can be staggered because of the diameter difference of fixed shifting block nail, eliminate each because of the angle that slidingtype shifting block is swung
The scale error of shifting block diameter superposition, further improves the precision of coded lock, the cunning of arcuate structure when fixed shifting block nail is mutually dialled
Dynamic shifting block, effectively increases intensity, prevent in use process because operator exert oneself it is excessive due to coded lock inner disc is caused to damage,
The direct fracture for even resulting in sliding shifting block, causes the damage of coded lock, also effectively extends the service life of coded lock.
