CN2539803Y - Billiard latch with multiple locking mechanism - Google Patents

Abstract

The utility model relates to a billiard latch with multiple locking mechanisms. The billiard latch comprises a latch body, a latch core, and a locking mechanism consisting of a side pillar billiard and a lock-in side pillar, and also has a locking mechanism consisting of an ordinary billiard group. Without increasing the volume of the latch, the latch is made to have a dual structure of the ordinary billiard latch and the inner pressure type side pillar billiard latch by a subtle design, so the safety and the guard against theft are improved greatly, and any billiard latch with single structure can not be compared with the billiard latch with multiple locking mechanisms.

Description

A kind of cylinder lock with multiple locking mechanism

Technical field the utility model belongs to a kind of lockset, particularly relates to a kind of cylinder lock set.

The background technology cylinder lock is a kind of common lockset, and the common spring lock is to lock lock core by the dislocation between the pellet shot from a slingshot up and down in each pellet shot from a slingshot group to rotate.Also having a kind of side column inner pressed cylinder lock, is to utilize cooperating of pellet shot from a slingshot and side column, controls (referring to the ZL99233344.X) that lock core rotates relative to lock body by moving of side column.These two kinds of problems that are latched in are, all have only a locking mechanism, no matter any when being locked in independent use, its security performance and theftproof performance all are limited.

The summary of the invention the purpose of this utility model provides the cylinder lock of the locking mechanism of a kind of locking mechanism with common spring lock and side column inner pressed cylinder lock, and its security performance and theftproof performance are all much higher than each lock.

The technical solution of the utility model comprises lock body, lock core, pellet shot from a slingshot, pellet shot from a slingshot is divided into common spring group and side column pellet shot from a slingshot, the common spring hole that has mutual dislocation on the lock core and side column pellet shot from a slingshot hole are to adapt to different pellets shot from a slingshot, also have the side column groove on the lock core, the inboard of side column groove communicates with the side in side column pellet shot from a slingshot hole, and with side column pellet shot from a slingshot hole approximate vertical, the corresponding pellet shot from a slingshot hole that has with lock core common spring hole on the lock body, the corresponding square groove that has with lock core side column groove, each side column pellet shot from a slingshot all has a circle ∨ type groove on diverse location, be provided with locking side column in the side column groove, the inboard of locking side column is the ∧ type, can match with the ∨ type groove on the side column pellet shot from a slingshot, the outside of locking side column is a square, can match with the square groove on the lock body, and locking side column is provided with step, with be fixed with pressing plate on the corresponding lock core side column of the step groove outside, between pressing plate and side column step, be provided with the side column spring.

During the utility model locking, side column groove on the lock core is corresponding with the square groove on the lock body, and the inboard of locking side column is under the compressing of side column pellet shot from a slingshot outer wall, and its outside is stretched in the lock body square groove, lock core can not rotate, and the mutual dislocation of pellet shot from a slingshot up and down in each common spring group further locks lock core simultaneously.When unblanking, after key inserts lockhole, the tartar that mutual dislocation is arranged on the key, each tartar forces the shift in position of common spring group and side column pellet shot from a slingshot respectively, at this moment, ∨ type groove on the side column pellet shot from a slingshot all overlaps, be on the straight line, locking side column is under the effect of side column spring, its ∧ type inboard is slipped in the ∨ type groove on the side column pellet shot from a slingshot, and withdraw in lock body square groove in the outside of locking side column, simultaneously, the contact surface of pellet shot from a slingshot overlaps with the contact surface of lock core and lock body about in the common spring group, and lock core can rotate.

The utility model is not increasing under the long-pending situation of lock body, makes lock have the double locking mechanism of common spring lock and side column inner pressed cylinder lock simultaneously by ingenious design, and its safety and theftproof improve greatly, are that any single structure cylinder lock is incomparable.

Further specify the technical solution of the utility model below in conjunction with accompanying drawing.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the A-A sectional view of Fig. 1.

Fig. 3 is locking states figure of the present utility model.

Specific embodiment accompanying drawing discloses an embodiment of the present utility model, comprise lock body 2, lock core 3, pellet shot from a slingshot 8,15, marble spring 6,11, spring die 7, pellet shot from a slingshot is divided into common spring group 8 and side column pellet shot from a slingshot 15, have orthogonal common spring hole 4 and side column pellet shot from a slingshot hole 10 on the lock core 3 to adapt to common spring group 8 and side column pellet shot from a slingshot 15, also have side column groove 14 on the lock core 3, the inboard of side column groove 14 communicates with the side in side column pellet shot from a slingshot hole 10, and it is vertical with side column pellet shot from a slingshot hole 10, on the lock body 2 with the 4 corresponding pellet shot from a slingshot holes 5 that have, lock core common spring hole, with the lock core side column groove 14 corresponding square grooves 12 that have, each side column pellet shot from a slingshot 15 all has a circle ∨ type groove 9 on diverse location, be provided with locking side column 13 in the side column groove 14, the inboard of locking side column 13 is the ∧ type, can match with the ∨ type groove 9 on the side column pellet shot from a slingshot 15, the outside of locking side column 13 is a square, can match with the square groove 12 on the lock body 2, locking side column 13 is provided with step 16, with be fixed with pressing plate 18 on step 16 corresponding lock core side column grooves 14 outsides, between pressing plate 18 and side column step 16, be provided with side column spring 17.Fig. 1, lock shown in Figure 2 are in opening.Orthogonal tartar is arranged on the key 1, each tartar forces the shift in position of common spring group 8 and side column pellet shot from a slingshot 15 respectively, at this moment, ∨ type groove 9 on the side column pellet shot from a slingshot 15 all overlaps, be on the straight line, locking side column 13 is under the effect of side column spring 17, its ∧ type inboard is slipped in the ∨ type groove 9 on the side column pellet shot from a slingshot 15, withdraw in lock body square groove 12 in the outside of locking side column 13, simultaneously, the contact surface of pellet shot from a slingshot overlaps with the contact surface of lock core 3 and lock body 2 about in each common spring group 8, and lock core 3 can rotate.During locking, when key 1 was extracted in the direction of arrows, side column pellet shot from a slingshot 15 moved down under the effect of spring 11, forced locking side column 13 to move in the square groove 12 that stretches into lock body 2 along the direction of arrow, and lock core 3 is stuck.The pellet shot from a slingshot mutual dislocation further locks lock core 3 about simultaneously in each common spring group 8.Fig. 3 is the lock under the locking states.
