Description

A kind of lockset

Technical field

The utility model relates to a kind of lockset, refers in particular to the lockset that has many row's billiards structure lock cores and matched key.

Background technology

In the lockset, arrange the existing patent application of lock core of billiards structure at present, be exactly this lock core as the patent No. 2004200656756 more.Many row's lock cylinders are better than present widely used cross structure lock core burglary insurance performance.But existing many row's billiards structures all are that pellet shot from a slingshot vertically is set on the face of cylinder of lock core, and the burglary insurance performance does not also reach optimal state.

The utility model content

The technical problems to be solved in the utility model provides a kind of lockset, increases again on the basis of the lock core of this lockset row's pellets shot from a slingshot how to be provided with marble amount, forms new structure, makes its safety performance better.

The technical problems to be solved in the utility model is realized by following scheme: a kind of lockset, comprise many row's billiards structure lock cores, keyhole and supporting key, it is characterized in that: described lock core one end is a boss, a circle annular groove is opened at the boss back side, a circle pellet shot from a slingshot hole is symmetrically opened in the bottom of groove, the direction in this circle pellet shot from a slingshot hole is vertical with the direction of described many row's pellets shot from a slingshot, and the anti-dial of an annular that is mated is housed in the described groove.

The utility model also comprises following scheme: in the described circle pellet shot from a slingshot hole, have two of symmetry to be blind hole, all the other are through hole, and pellet shot from a slingshot is housed in the through hole.Have the hole of matching on the anti-dial of described annular with described through hole.Described key root is fixed with positioning disk, is fixed with the reference column that a circle matches with pellet shot from a slingshot in the described through hole on the positioning disk.

The utility model has the advantages that: establish a circle pellet shot from a slingshot on this lock core boss at one end again, form crisscross pellet shot from a slingshot and arrange, this makes that its marble amount is more, and the burglary insurance performance is better.When using this lockset, when normally opening with key, the anti-dial of annular rotates with lock core; During with the foreign matter unnormal unlocking, no matter turn left or when turning right to 45 jiaos, the pellet shot from a slingshot in all through holes will eject, and wherein has two pellets shot from a slingshot to be bound in the blind hole, thereby has reached antitheft purpose.The pellet shot from a slingshot of this lockset is arranged in length and breadth and can be varied to multiple arrangement mode, and the reference column number can have multiple variation combination on pellet shot from a slingshot number of establishing on the boss and the matched key.

The specific embodiment

Below in conjunction with accompanying drawing for an embodiment.As Fig. 1, shown in Figure 4, vertical symmetry is established 8 row's pellets shot from a slingshot 2 on the face of cylinder 1 of lock core.As shown in Figure 1-Figure 3, lock core one end is a boss 3, and a circle annular groove 4 is opened at boss 3 back sides, and circle 8 pellet shot from a slingshot holes are symmetrically opened in the bottom of groove 4, and are horizontal.Wherein symmetrical two are blind hole 5, and all the other are through hole 6, in the through hole 6 pellet shot from a slingshot are housed.As Fig. 5-shown in Figure 7, the anti-dial 7 of an annular that is mated is housed in the groove 4, have 6 holes 8 of matching on the anti-dial 7 of annular with through hole 6.As Fig. 8, shown in Figure 9, the key root is fixed with positioning disk 9, is fixed with 6 reference columns 10 that match with pellet shot from a slingshot in the through hole 5 on the positioning disk 9.
