Closing, have is coordinated with limit bolt by the alveolus of cylinder.Make the alveolus on each blade or cylindrical billiard align by key, make limit
Bolt one end enters coupling alveolus, and disengaging is engaged with lock tube, and key can be made to drive lock gall to rotate.The theftproof performance of this lock is excellent
Point is that the processing of lock tube endoporus is simple, it is adaptable to the calabash lock core of Europe superscript lock standard, but the following antitheft and technical problem of its existence:
1, under technical unlocking state, rotate lock gall by flat-shaped instrument, make limit bolt on lock gall and lock tube produce to
The active force of the heart, is then instigateeed the alveolus of blade or the screw-like alveolus of cylindrical billiard and limit bolt teeth one by one by group hook
The position of engagement, instigates sense substantially, makes limit bolt corresponding with the screw-like alveolus of the alveolus of blade or cylindrical billiard, is further continued for rotating
Lock gall, makes limit bolt engage with the alveolus of blade or the alveolus of cylindrical billiard, can be easily opened anti-theft lock.Its theftproof performance is relatively
Difference.
If 2 select blade construction, each blade need to coordinate with the blade slotted eye of axial distribution on lock gall, blade and leaf
The dimensional tolerance of sheet slotted eye and the required precision of form and position tolerance are higher, cause difficulty of processing big, and production efficiency is low.On lock gall
The blade slotted eye coordinated with blade with the limit croze mouth of limit bolt matched in clearance is rectangle, needs through punching back chipping after processing,
Its difficulty of processing is relatively big, and production efficiency is relatively low.
If 3 select cylindrical billiard structure, although the circular hole coordinated with it on lock gall is easily worked, but on cylindrical billiard
Not only to process the screw-like alveolus engaged with limit bolt teeth, screw-like alveolus place axial location also will differential with key
Corresponding conjunction, volume is the least, and processing difficulty is relatively big, and production efficiency is relatively low.
Summary of the invention
The purpose of the present invention is exactly on the basis of the hydrant anti-theft lock structure of limit, while developing skill property opens difficulty,
Make its structure developing skill property can not only open difficulty, moreover it is possible to improve production technology further, to improve industrialized production energy
Power.
For realizing described purpose, the present invention adopts the following technical scheme that described chief and vice bolt coupling formula anti-theft lock, including lock
Set, lock gall, limit bolt, coupling.At the axial direction of lock gall, it is provided with positive limit bolt and a secondary bolt.Described positive limit bolt and lock gall
On positive limit croze matched in clearance；Described secondary bolt and the secondary croze matched in clearance on lock gall.Correspondence on each coupling
The side of positive limit bolt is provided with detent recess；On each coupling, the side of corresponding secondary bolt is provided with V-arrangement alveolus.The side of positive limit bolt
With lock tube inner circle groove fit；The boss of positive limit bolt opposite side engages with the detent recess of coupling.The side of secondary bolt and lock tube
Inner circle groove fit；The V-arrangement teeth of secondary bolt opposite side engage with the V-arrangement alveolus of coupling.The lock tube inner circle coordinated with positive limit bolt

Sub-line material, requires to be cut into positive limit bolt, secondary bolt and coupling sub-line material required length according to design, then according to design requirement
It is processed into required shape.Positive limit croze and secondary croze on described lock gall are processed by milling cutter, positive limit croze
It is technique half slot with the axial two ends of secondary croze.Coupling pilot trench on described lock gall is processed by milling cutter, on lock gall
Coupling pilot trench be radially through slotted eye, the axial two ends of coupling pilot trench are technique half slot.Positive limit croze on lock gall and secondary bolt
Fluted shaft is technique half slot, the most just radius of machining of milling cutter to two ends, solves croze two ends, the limit the most unmanageable problem of Zhi Kou.
Coupling pilot trench two ends on lock gall are technique half slot, it is to avoid unmanageable rectangle.
The present invention is by positive limit bolt and the positive limit croze matched in clearance on lock gall；By secondary bolt and the secondary bolt on lock gall
Groove matched in clearance, is engaged by the boss of the detent recess on each coupling with positive limit bolt opposite side, is to insert key to make lock core
The essential condition rotated.By the V-arrangement alveolus on each coupling and the V-arrangement teeth of secondary bolt opposite side and the V-arrangement tooth on coupling
Groove engages, and is to insert the essential condition that key makes lock core rotate, is also under technical unlocking state, causes the bar of erroneous judgement
Part, because in technical unlocking formula, is difficult to determine which V-arrangement alveolus is the alveolus making lock core really rotate unlatching.If positive limit bolt
It is locked out lock core with the side of secondary bolt and the purpose of lock tube inner circle groove fit, stops non-key operated；If joining with positive limit bolt
The rotating angular breadth of round recessed in the lock tube closed, rotating angular breadth time at a fully engaged more than secondary bolt and V-arrangement teeth, its
Purpose is exactly when technical unlocking, and when preventing lock core from rotating, positive limit bolt produces frictional force immediately with round recessed in lock tube, avoids
Secondary bolt, and directly feel engaging of positive limit bolt and coupling detent recess.When round recessed positive and negative in the lock tube that positive limit bolt coordinates
Corner width, rotating angular breadth time at a fully engaged more than secondary bolt and V-arrangement teeth, under technical unlocking state, it is impossible to
Use the frictional force of positive limit bolt, and only with the frictional force of secondary bolt, sensation instigates V-arrangement alveolus and the secondary bolt of coupling one by one
The engagement of V-arrangement teeth, but, the only one of which that V-arrangement alveolus on coupling is at least two, correct, at one group of multiple coupling
In be difficult to each and every one can accuracy of judgement, one is not in place, and positive limit bolt and secondary bolt cannot be made to engage with coupling.Positive limit bolt,
Secondary bolt can not be at a fully engaged with coupling, it is meant that lock core cannot rotate, and i.e. can not enter opening.The present invention is by pair
Limit bolt is that technical unlocking shines into a kind of illusion with engaging of coupling, is added to the difficulty of technical unlocking, the most positive limit bolt, pair
Limit bolt can coordinate the mechanical strength added the torsion that lock core violence nature is opened jointly.Vital part in its structure
Coupling, from being the most i.e. different from traditional blade, is different from again traditional pellet, from structure also with traditional pellet and leaf
Sheet is otherwise varied, because the structure of this coupling must complete main antitheft merit with positive limit bolt and the mutual coordinated of secondary bolt
Energy.
The present invention with positive limit bolt, secondary bolt, coupling cross section gabarit for element line, longitudinal extension, be just processed into respectively
Limit bolt, secondary bolt, coupling sub-line material, require positive limit bolt, secondary bolt and coupling sub-line material are cut into required length, so according to design
Require to be processed into required shape according to design afterwards.Positive limit croze and secondary croze on described lock gall are processed by milling cutter
Forming, the axial two ends of positive limit croze and secondary croze are technique radius circular groove.Coupling pilot trench on described lock gall passes through milling cutter
Processing, the coupling pilot trench on lock gall is the through slotted eye of radial direction, and the axial two ends of coupling pilot trench are technique radius round slot bore.The present invention
