Detailed description of the invention
Below in conjunction with accompanying drawing, concrete further instruction is done to the utility model.A kind of can the blade lock core of anti-technical opening, it comprises outer lock tube 1, interior lock tube 2, shifting block 3, anti-drilling sheet 4 and Explosion-proof cap 5, interior lock tube 2 to be interted in outer lock tube 1 and by its outer face of anti-drilling sheet 4 capping, shifting block 3 is docked in interior lock tube 2 by shaft coupling 31, shifting block 3 can be driven to rotate unblank when interior lock tube 2 is rotated, interior lock tube 2 offers the blade groove 21 that blade 6 is installed in some roads, blade 6 is slidably mounted in blade groove 21 by leaf spring 61, described interior lock tube 2 also offers the lock pin groove 71 installing lock pin 7, when key 8 inserts, tartar 81 on key 8 makes the V-shaped groove alignment on blade 6 form avoiding hollow groove, lock pin 7 on blade 6 is pushed in V-shaped groove under the effect of lock pin spring 72, lock pin 7 is sunk, it is characterized in that: described lock pin groove 71 upper end is also provided with clutch slot 91, the clutch-plate 9 that can be in axial sliding is installed in clutch slot 91, the corresponding lock pin 7 of clutch-plate 9 is provided with the boss 92 to lower convexity, lock pin 7 upper end is provided with the groove 73 that can coordinate with boss 92, when lock core is in lockup state, lock pin 7 rise make the boss 92 on clutch-plate 9 insert on it groove 73 in, play the axial locking effect to clutch-plate 9,
Described clutch-plate 9 upper surface is also provided with Anti-rotary block 93, and in outer lock tube 1, be provided with the annular avoiding hollow groove 11 coordinated with Anti-rotary block 93, when lock core is in lockup state, Anti-rotary block 93 and annular avoiding hollow groove 11 sequence, play the object of locking preventing interior lock tube 2 from rotating;
Described key 8 being provided with link gear can drive clutch-plate 9 to move axially when lock pin 7 sinks to unblanking, make the Anti-rotary block 93 on clutch-plate 9 enter in annular avoiding hollow groove 11, rotates key 8 and the rotation of interior lock tube 2 can be driven to unblank.
Described lock pin spring 72 is arranged between lock pin 7 and clutch-plate 9, and lock pin spring 72 produces thrust and promotes lock pin 7 downwards all the time, wherein in order to make lock pin uniform stressed, lock pin spring can be provided with two or more, make lock pin parallel motion, prevent stuck, promote lockset stability.
Also be provided with brake spring 94 in described clutch slot 91, brake spring 94 produces thrust and inwardly promotes clutch-plate 9 all the time, and the boss 92 on clutch-plate 9 is alignd with the groove 73 of lock pin 7.
Described Anti-rotary block 93 is provided with three pieces, and before, during and after being distributed in clutch-plate 9, accordingly, described annular avoiding hollow groove 11 is provided with three and Anti-rotary block 93 one_to_one corresponding equally.Wherein, the width of annular avoiding hollow groove all needs the width less times greater than Anti-rotary block, and at the notch position of avoiding hollow groove to fillet, makes Anti-rotary block slip in avoiding hollow groove smoothly.
The inner hole wall of described outer lock tube 1 is provided with axially extended lock groove 12, lock groove 12 is tangent with annular avoiding hollow groove 11, Anti-rotary block 93 on described clutch-plate 9 can be in axial sliding in this lock groove 12, the dislocation realizing Anti-rotary block 93 and annular avoiding hollow groove 11 with overlap.Lock groove is the groove processed on outer lock tube inner hole wall material, and this lock groove and outer lock tube end face run through, to have the Anti-rotary block of the accommodating clutch-plate in enough spaces when interior lock tube is installed.
Described link gear comprises the pintle 82 being arranged on key 8 tail end swingably, and the startup sheet 83 be located in interior lock tube 2, start sheet 83 by spring supporting all the time to jack-up in lockhole, when key 8 inserts in lock core, starting sheet 83 drives pintle 82 upwards to overturn, make pintle 82 drive clutch-plate 9 outwards to move, the Anti-rotary block 93 on clutch-plate 9 is entered in avoiding hollow groove 11.Wherein, pintle is hingedly mounted in the mounting groove of key tail end, turns over more smooth and easy and accurate on when unblanking to make it, is provided with the jacking block 85 promoted by spring in key 8, jacking block can low pressure in the swing arm of pintle.When on pintle, overbanking arm and jacking block are subjected to displacement, jacking block 85 under spring force rapid driven forward swing arm makes pintle entirety upwards dig.
Described startup sheet 83 upper end is provided with pilot hole 84, and when key 8 inserts, pintle 82 enters and drives clutch-plate 9 to move in this pilot hole 84.
Described clutch-plate 9 is provided with contact chip 95 and is positioned at pilot hole 84 upper end, pintle 82 turns over be pressed on and this contact chip 95 promotes clutch-plate 9 displacement and unlock.
Operating principle: as shown in Figure 5: when lock core is locked, lock pin is in upper state, in the groove 73 that the boss 92 on clutch-plate 9 is inserted on lock pin, plays the axial locking effect to clutch-plate 9.Anti-turntable on clutch-plate now and the annular avoiding hollow groove on outer lock tube are in misaligned state, are equivalent to outer lock tube and interior lock tube is in key connection status, play the effect relatively fixing inside and outside lock tube.In addition clutch-plate body and on anti-turntable and boss formed by metal material integral productions such as high strength manganese steel, for traditional blade and billiards structure intensity, in this case, clutch-plate locking structure has better anti-shearing and impact property, effectively can resist lawless person to use violent means pressure rotary locking cylinder, blade and pellet are damaged reach and to the object of unblanking, promote lockset safety.
As shown in Figure 6,7, when needs are unblanked, user inserts key, first the blade in interior lock tube carries out code under the effect of tartar on the key, the V-shaped groove alignment on some blades is made to form avoiding hollow groove, lock pin 7 on blade 6 is pushed in V-shaped groove under the effect of lock pin spring 72, makes lock pin 7 integral sinking (this section of releasing process and the conventional leaf mortice lock process of unblanking are as good as), completes first and heavily unlock.Wherein, after lock pin sinks, the groove 73 on it is separated with the boss 92 on clutch-plate, removes the axial locking effect to clutch-plate, and clutch-plate is able under the effect of external force, do axial slip motion.
After blade unlocks, user needs to be continued by key inwardly to promote, and when the pintle of key tail end enters in lockhole the position starting sheet 83, starts sheet 83 by pintle 82 upwards jack-up, pintle is inserted in pilot hole 84.Key move on promote shaft coupling dock with shifting block.The pintle simultaneously entered in pilot hole continues upwards to overturn, and promote clutch-plate 9 by contact chip 95 and outwards move axially, anti-turntable on clutch-plate and the annular avoiding hollow groove on outer lock tube are coincided, anti-turntable loses radial support, user rotates key and drives interior lock tube to rotate, anti-turntable enters in annular avoiding hollow groove smoothly, and interior lock tube drives shifting block to rotate by shaft coupling, realizes unlocking function.
Compared with traditional blades or billiards lock structure, in this structure, add the second heavy locking structure, only have after the first heavy blade lock unlocks, the second weight structure could be driven to unlock by the key pintle structure of uniqueness.Simultaneously the second heavy exclusive unlocking manner is also distinguished and existing unlocking structure, makes existing unlocking tool because radially inserting pilot hole, and cannot promote clutch-plate motion unblock.In addition, the second clutch-plate unlocking structure weighed is hidden in interior lock tube, the structure in lockhole and common blade is locked and is as good as, and therefore lawless person is difficult to distinguish, and makes it unblank never to succeed by the mode that tradition opens blade lock, promotes the safety of lockset further.There is the twisting of explosion-proof power, preventing collision key, the maltilevel security preventing functions such as anti-technical opening, therefore can extensively promote the use of in all kinds of lock.
