Description
Technical field
The utility model relates to a kind of lock core.
Background technology
Existing lock core, generally be by at standing part, the hoodle group that many groups are made of two hoodles is set between rotating part, its operating principle is to make the junction of two hoodles of all hoodle groups be positioned at standing part by key, the junction of rotating part, make rotating part break away from the restriction of hoodle and can rotate along standing part, this kind lock core, because the junction of two hoodles is positioned at standing part, during the junction of rotating part, having trickle physical phenomenon occurs, when unblanking with crack tool, the robber unblanks by these trickle physical phenomenons of perception, make the lock theftproof performance of the above-mentioned type poor, cracked by the robber easily.
Summary of the invention
Goal of the invention of the present utility model is to provide that a kind of robber is not easy to crack, can effectively prevents the Teethed bolt lock pearl formula idle-run lock pin of the destructive release of robber.
The utility model is to realize like this, comprise standing part, rotation is arranged on the rotating part that has keyhole and array hoodle hole of standing part, key, be arranged on hoodle and spring in the hoodle hole, the password projection that is provided with deep mixed password recess on the key or just differs in corresponding hoodle hole, its special feature is to be provided with groove perpendicular to the rotating part in array hoodle hole, groove depth is gone into in the part hoodle hole, slide in the groove and be provided with tooth bar, the spacing of tooth bar recess is consistent with spacing between the hoodle hole, that side that is positioned at groove on the hoodle is provided with recess, the degree of depth of recess is consistent with the distance that tooth on the tooth bar is deep in the hoodle hole, be provided with more than one screens recess at the back side of tooth bar, the corresponding screens standing part of recess, rotating part is provided with screens hoodle hole, is provided with spring and a pair of screens hoodle in screens hoodle hole.During work, key inserts in the keyhole of rotating part, on the key password recess or password projection move to decoded positions with hoodle, make the recess of all hoodles all be positioned at the groove place, like this, tooth bar moves with regard to not being subjected to the constraint of hoodle, make the screens at the tooth bar back side move to screens hoodle place with recess, like this, make the joint of two screens hoodles be positioned at the joint of rotation, standing part, make rotating part break away from the constraint of screens hoodle and freely rotate, move, finish the work of unblanking thereby drive coupled corresponding latch mechanism.When needing locking, make tooth bar reset to locked position of coupler, the joint of two screens hoodles is staggered in the joint of rotation, standing part, extract key out, like this, under the effect of hoodle, tooth bar can not move, make the joint of two screens hoodles maintain the joint that staggers in rotation, standing part, rotating part can not be rotated under the constraint of screens hoodle.
