Detailed description of the invention
Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Referring to figs. 1 through Fig. 3, one embodiment of a kind of lock core structure of the present utility model is proposed, comprise mutually adaptive lock core, key 200, lock core comprises lock gall housing 101, and lock gall housing 101 is provided with and can inserts inside for key 200 and carry out unblanking or the keyhole 102 of lock operation.
Lock core structure is provided with the first latch-up structure, the second latch-up structure.
First latch-up structure comprises the some hoodles 301 along keyhole 102 arranged distribution be located in lock gall housing 101, be located at corresponding with hoodle 301 on key 200 and the ball race 302 of adaptation, and key 200 inserts lock core inside and makes hoodle 301 and ball race 302 mutually be engaged thus the first latch-up structure can be made to be converted to unlocking condition.
Second latch-up structure comprises the bar shaped groove 401, adaptive and can enter bar shaped spacer 402 in bar shaped groove 401, be located at and can carry out along bar shaped groove 401 arranged distribution the movable block 403 that laterally moves left and right in lock gall housing 101 by inlay card with bar shaped groove 401 of connection lock gall housing 101 inside be located on lock gall housing 101 sidewall.Bar shaped spacer 402 lower surface is provided with some locating grooves 404, and movable block 403 upper surface is provided with some adaptations corresponding to locating groove 404 and mutually can be engaged thus makes the second latch-up structure be converted to the mobile draw-in groove 405 of unlocking condition.
Second latch-up structure can be stirred movable block 403 and carries out moving left and right thus make some mobile draw-in grooves 405 all corresponding with bar shaped groove 401 and can be engaged with locating groove 404 fixing thus what carry out unblanking is the rail groove 406 of irregular curve groove shape after also comprising the insertion keyhole 102 be located on key 200 sidewall.
Spring 407 is arranged with between bar shaped groove 401 and bar shaped spacer 402.
After original key 200 inserts keyhole 102, the ball race 302 on key 200 and the hoodle 301 in lock gall housing 101 are mutually adaptive to be also engaged thus the first latch-up structure can be made to be converted to unlocking condition; Simultaneously, rail groove 406 on key 200 can be stirred movable block 403 and carries out moving left and right thus make mobile draw-in groove 405 all corresponding with bar shaped groove 401 and can be engaged with the locating groove 404 of bar shaped spacer 402 lower end fixing thus unblank, because mobile draw-in groove 405 and locating groove 404 are mutually adaptive and be engaged, bar shaped spacer 402 is made to enter in bar shaped groove 401 by inlay card smoothly, final lock core can rotate thus lock core structure can be unblanked smoothly, there is dual latch-up structure, reliability is high, and anti-theft effect is strong.And when lock core structure is subject to illegally unblanking, even if the non-original key inserted can open the first latch-up structure smoothly, this does not arrange rail groove 406 on the key, also be difficult to stir movable block 403 carry out moving left and right and then making mobile draw-in groove 405 all corresponding with bar shaped groove 401 and be engaged with locating groove 404, that is, bar shaped spacer 402 cannot enter in bar shaped groove 401 by inlay card, causes lock core to rotate and to make lock core structure be in blocking all the time.That is, lock core structure of the present utility model is provided with two relockings, and effectively stopped the potential safety hazard of illegally unblanking, security performance is high, high safety, and anti-theft feature is very powerful.And structure design advantages of simple, principle advantages of simple, working stability is reliable, makes that lockset is more durable and fault rate is lower, and use reliable and stable, anti-theft function is remarkable.In addition, rail groove 406, in irregular curved groove shape, needs the unlocking tool of original key 200 or specialty customization just can unblank, robber adopts general tool to be difficult to unblank, and anti-technical opening performance is good, and reliability is high, security performance is high, security protection excellent effect.Meanwhile, the adaptive goodness of fit between the rail groove 406 of unconventional property shape and movable block 403 is higher, needs to carry out specific customization, region mutual opening rate and repetitive rate lower, be not easy to be copied, the theftproof performance of lockset is higher.
Key 200 sidewall is provided with linear locating slot 501, and keyhole 102 inside is provided with the adaptive locating pin 502 that also can along locating slot 501 carry out movement corresponding to locating slot 501.When inserting key 200 toward keyhole 102, the locating slot 501 on key 200 need aim at the locating pin 502 in keyhole 102, and key 200 could advance smoothly in keyhole 102, and in progradation, locating pin 502 moves along locating slot 501.Locating slot 501 serves positioning action with the setting of locating pin 502, key 200 can be inserted in keyhole 102 rapidly and accurately, make the update of key 200 fast and convenient, easy to use and flexible.
Lock core structure of the present utility model is provided with the first latch-up structure, the second latch-up structure, possesses two relockings, and effectively stopped the potential safety hazard of illegally unblanking, security performance is high, high safety, and anti-theft feature is very powerful.And structure design advantages of simple, principle advantages of simple, working stability is reliable, makes that lockset is more durable and fault rate is lower, and use reliable and stable, anti-theft function is remarkable.In addition, rail groove 406, in irregular curved groove shape, needs the unlocking tool of original key 200 or specialty customization just can unblank, robber adopts general tool to be difficult to unblank, and anti-technical opening performance is good, and reliability is high, security performance is high, security protection excellent effect.Meanwhile, the adaptive goodness of fit between the rail groove 406 of unconventional property shape and movable block 403 is higher, needs to carry out specific customization, region mutual opening rate and repetitive rate lower, be not easy to be copied, the theftproof performance of lockset is higher.In addition, key 200 sidewall is provided with linear locating slot 501, and keyhole 102 inside is provided with the adaptive locating pin 502 that also can along locating slot 501 carry out movement corresponding to locating slot 501.Locating slot 501 serves positioning action with the setting of locating pin 502, key 200 can be inserted in keyhole 102 rapidly and accurately, make the update of key 200 fast and convenient, easy to use and flexible.The utility model achieves a kind of reasonable in design, has double locking structure, anti-theft feature is powerful, it is reliable and stable to use, be difficult to copy, region mutual opening rate and repetitive rate lock core structure lower, convenient to use.
The foregoing is only preferred embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every equivalent structure transformation utilizing the utility model manual and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
