Description

A kind of combined anti-theft lock core
Technical field
The utility model belongs to the lock core of mechanical lock, is specifically related to a kind of combined anti-theft lock core.
Technical background
Existing all kinds of lock core comprises outside lock gall shell and inner lock gall composition, the lock gall pellet shot from a slingshot hole that distributes and embark on journey and arrange on the lock gall, and every round is several more than 3, has on the lock gall shell and corresponding lock gall shell pellet shot from a slingshot hole, lock gall pellet shot from a slingshot hole.Be provided with down pellet shot from a slingshot in lock gall pellet shot from a slingshot hole and the lock gall shell pellet shot from a slingshot hole, lock gall shell pellet shot from a slingshot is provided with fastener pellet shot from a slingshot, back-moving spring and envelope pearl in the hole, and under locking state, half is positioned at lock gall pellet shot from a slingshot hole the fastener pellet shot from a slingshot, and half is positioned at lock gall shell pellet shot from a slingshot hole.Insert the keyhole of lock gall when key after, the key extruding is pellet shot from a slingshot and fastener pellet shot from a slingshot down, forces all fastener pellets shot from a slingshot just to be got back in the lock gall shell pellet shot from a slingshot hole, and lock gall is not stuck, thereby it is flexible to drive dead bolt by the shifting block on the lock gall to rotate lock gall.After key extracted from the hole, the fastener pellet shot from a slingshot came back in the lock gall under the effect of back-moving spring, reaches locking state.The lock core theftproof performance of this class formation is relatively poor, can pass through special instrument, with certain skill the fastener pellet shot from a slingshot is pushed in the lock gall shell one by one, opens theftproof lock thereby lock gall can be rotated.
The utility model content
The utility model provides a kind of combined anti-theft lock core of anti-technical unlocking at the defective that prior art exists, and is safe and reliable, the theftproof performance height.
For this reason, the utility model is taked following technical scheme: a kind of combined anti-theft lock core, comprise key, lock gall shell and have the lock gall of keyhole, have the lock gall pellet shot from a slingshot hole of embarking on journey and arranging vertical with keyhole and that communicate on the lock gall, have in the described lock gall shell and corresponding lock gall shell pellet shot from a slingshot hole, lock gall pellet shot from a slingshot hole, lock gall pellet shot from a slingshot hole communicates with lock gall shell pellet shot from a slingshot hole to be provided with in the cavity that forms and comprises the locking device of pellet shot from a slingshot, fastener pellet shot from a slingshot, back-moving spring down, it is characterized in that: describedly be provided with snakelike tartar on the key; The side top of described lock gall has the side direction blade marble hole that communicates with keyhole, be provided with blade marble and marble pressuring spring in this blade marble hole, draw-in groove, step are formed respectively on the top of described blade marble and bottom, described step and snakelike tartar coupling on the key; The top of described lock gall axially has a translot along it, is provided with the card article of a restorable in the described translot, and the arc groove that has in the top of this card article and the lock gall shell matches, and the bottom of described card article and draw-in groove width match and be against on the blade marble.When not inserting key, the fastener pellet shot from a slingshot circumferentially locks lock gall, and marble pressuring spring remains on staggered positions with draw-in groove on the blade marble and card article, and card article is between lock gall shell and lock gall, lock gall is carried out circumferentially (being the key turns direction) locking, thereby realize circumferential double locking.After inserting key, away from the lock gall center position, the other end and lock gall external diameter are tangent under the key thrust for following pellet shot from a slingshot and fastener pellet shot from a slingshot; The step of blade marble and snakelike tartar coupling on the key, key has the thrust of side direction to blade marble, make blade marble generation lateral displacement, make the corresponding draw-in groove of card article, for the card article activity provides the space, make the top of card article can be rotated out arc groove, so that the complete release of lock core, can rotate freely.The utility model has additionally increased a kind of latch-up structure to lock gall, has theftproof performance preferably, and is safe and reliable.
Lock gall outer wall and intersection, blade marble hole form groove, are provided with a blank cover in the groove.Blank cover is inlaid in the groove, can prevent effectively that the fastener pellet shot from a slingshot from entering in the blade marble hole when lock gall rotates, and guarantees that lock gall can rotate smoothly.
Described marble pressuring spring is against on the lock gall inwall, and marble pressuring spring is arranged between lock gall inwall and the blade marble, is positioned at the space of sealing, is difficult for being subjected to displacement.
Described card article comprises transverse part connected vertically and vertical part, and the two ends of transverse part form the extension that exceeds the vertical part, and described translot comprises the embedded spring groove that is formed on its two ends, between described embedded spring groove and the card article extension spring is set.Spring is arranged in the predetermined embedded spring groove, and spring is subjected to displacement when preventing the lock gall rotation, finishes the homing action of card article by this spring.
Described lock gall below forms the lock gall pellet shot from a slingshot hole that two rows have the front and back difference, every row's lock gall pellet shot from a slingshot hole count 〉=3.Many row pellet shot from a slingshot holes are set and increase the pellet shot from a slingshot hole count, can effectively increase the theftproof performance of lock core.
Described Feng Zhuyu lock gall shell interference fit, the corresponding lock gall in described blade marble hole radially locate to have make that translot and keyhole communicate between groove, be convenient to carry out a series of processing.
The beneficial effects of the utility model are embodied in: realize lock gall is circumferentially locked by the card article that can reset is set on lock gall top, compare conventional lock core this patent and additionally increased latch-up structure one, strengthened the theftproof performance of lock core, lock core is difficult to by technical unlocking; Groove in lock gall outer wall and the formation of intersection, blade marble hole is installed blank cover, can prevent effectively that the fastener pellet shot from a slingshot from entering in the blade marble hole when lock gall rotates, and guarantees that lock gall can rotate smoothly.
