Detailed description of the invention
With reference to accompanying drawing, the lockset of this anti-technical opening, comprise lock core 6 and lock body 16, described lock core 6 is provided with keyhole 20, the relative both sides of described keyhole 20 are provided with the first marble hole 7, and corresponding the first pellet 5 is set the first marble hole 7 is interior, 5 ＇, described lock body 16 is provided with second marble hole 17 corresponding with the first marble hole 7 of a side on described lock core 6, and be built-in with the second pellet 18 and the second spring 19 at the second marble hole 17, described lock body 16 inwalls are provided with circumferential groove 23, and on lock core 6, have a chute 11, on described lock core 6, be provided with some locking plates 13 with the relevant position of circumferential groove 23, the middle part of described locking plate 13 has through hole 14, and each locking plate 13 is furnished with corresponding pushing top spring 15.The key 1 using in the present invention is not only provided with on the two sides of key piece 2 and the first pellet 5, the shrinkage pool 3 of 5 ＇ couplings, also on key piece 2, be provided with the step 4 coordinating with described locking plate 13, have groove 21 at the opposite side of described lock core 6, this groove 21 communicates with the first marble hole 7 of this side, in described groove 21, be provided with lateral pin 8, the first pellet 5 ＇ of this side contact with described lateral pin 8, described groove 21 opening parts are provided with spring leaf 10, this spring leaf 10 uses as spring base, while setting, can not protrude the external peripheral surface of lock core 6, on described spring leaf 10, be equipped with the first spring 9, described the first spring 9 contacts with described lateral pin 8, after lateral pin 8 pressurizeds, due to self-return under the state that acts on pressurized not of the first spring 9, described lateral pin 8 is concordant with the outer circumference surface of described lock core 6 under blocking with the opposite face that the first pellet 5 ＇ contact, therefore, under normal circumstances, insert after matching degree key, after the pellet that the shrinkage pool of key piece contacts with lateral pin coordinates, lateral pin 8 is also concordant with the outer circumference surface of described lock core 6 with the opposite face that the first pellet 5 ＇ contact, when rotational lock core 6, can normally unblank, described lock body 16 inwalls are provided with the transverse pin slot 24 mating with described lateral pin 8, and this transverse pin slot 24 is used for holding the lateral pin 8 sliding.
The present invention is under blocking, and the second pellet 18, due under the elastic force effect at the second spring 19, promotes the second pellet 18, and push the first pellet 5, make the part of the second pellet 18 enter into the first marble hole 7 of lock core 6, therefore, lock core 6 is blocked by the second pellet 18, can not freely rotate.Locking plate 13 is due to the effect of pushing top spring 15 simultaneously, together overlapped, the end 12 of locking plate 13 is all positioned at chute 11, and the end 12 of locking plate 13 is also all positioned at the axial elongated slot 22 of described lock body 16, the end 12 of locking plate 13 is staggered with the circumferential groove 23 in lock body 16, thereby lock core 6 can not be in the interior rotation of lock body 16, so just in dual blocking.Now, if burglar inserts keyhole 20 with the object of the technical openings such as iron wire, the first pellet 5 ＇ of keyhole 20 are with regard to pressurized, and the first pellet 5 ＇ promote lateral pin 8 and move down, and make lateral pin 8 expose the groove 21 of lock core 6 and be stuck in the transverse pin slot 24 of lock body 16, the first spring 9 pressurizeds simultaneously.More insert object, it is more that lateral pin 8 is stuck in part in transverse pin slot 24, more difficult unlatching, and if adopt the object that inserts keyhole 20 to twist by force, more can not open.After the object pull-out of inserting, due to the effect of the first spring 9, make again lateral pin 8 returns.Therefore, this lockset, under blocking, has triple protection.
While unblanking, insert the key 1 of coupling, the first pellet 5 of shrinkage pool 3 side corresponding to lock core 6 of key piece 2 one sides mates, make the first pellet 5 promote the second pellet 18, and the second pellet 18 is left to the first marble hole 7, make the end of the first pellet 5 concordant with the outer circumference surface of lock core 6 simultaneously, simultaneously, the shrinkage pool of key piece 2 opposite sides mates with the first pellet 5 ＇ of lock core 6 opposite sides, the first position of pellet 5 ＇ in the time of blocking that makes this side, lateral pin 8 can not expose the groove 21 of lock core 6 and snap onto in the transverse pin slot 24 of lock body 16.Step 4 on key piece 2 mates with locking plate 13 simultaneously, due to the ladder on key piece 2 from low to high, thereby, can promote each locking plate 13 separates, make the end 12 of locking plate 13 enter separately corresponding circumferential groove 23 on lock body 16, locking plate 13 can be rotated in circumferential groove 23, now rotate key 1, be rotational lock core 6, just can reach the object of unblanking.
This structure of the present invention, scientific and reasonable, particularly lockset has triple antitheftly under blocking, and in the time of technical opening, difficulty is higher, and under the state of strong twistlock core, can not unblank, and its theftproof performance is high.
