Description
Technical field
The present invention relates to field of lockset, particularly a kind of multilayer lockset.
Background technology
The lock that uses now is to entangle lock core simply by lock body, is made up of inside and outside two groups of pellets shot from a slingshot, and lock pin driving lever sheet is connected on the lock core; So the non-constant of security performance of this lock, the robber firmly can open lock once turning round as long as insert lockhole with a slice hard steel plate; The property safety guarantee that the so poor lock of security performance can't be given the people, in order to address this problem, the normal at present CN201635504U anti-lock of stealing of a kind of twin-lock core as shown in Figure 1 that adopts; In it outer lock core not on the same group pellet shot from a slingshot be on the same plane; Be connected in outer lock core so robbery during its driving lever sheet when unblanking, can only pellet shot from a slingshot be backed down, can't open by force; But since its not on the same group pellet shot from a slingshot be even that to be on the same plane pellet shot from a slingshot that therefore adopts Multilayer lock core to transfer still limited, professional unlock staff still can be easy to open it.
Summary of the invention
To above problem, the present invention is through a kind of multilayer lockset of design, and the pellet shot from a slingshot in its each layer lock core is in Different Plane; So the position that pellet shot from a slingshot can be transferred is extremely many, even professional unlock staff also is difficult to open it fast, for reaching this purpose; The present invention provides a kind of multilayer lockset, comprises lock pin driving lever sheet, outer lock core, internal cylinder, key and lock body, and said outer lock core and internal cylinder are arranged in the lock body; Said outer lock core is at least one, and said lock pin driving lever sheet is arranged on outermost outer lock core bottom, and said internal cylinder is arranged in the outer lock core; On the said internal cylinder bullet groove is arranged, said outer lock core top and the bottom are provided with bullet groove, and bullet groove position, said outer lock core top is identical with the bullet groove of internal cylinder; Outermost layer outer lock core bottom is provided with group number and the identical bullet groove of outer lock core sum; Innermost layer outer lock core bottom is provided with one group of bullet groove, and each layer outer lock core is by the ecto-entad setting from more to less of bullet groove number, and said bullet groove is disposed with hoodle, spring and lead sealing from the inside to the outside; Said key adds 1 identical lock tooth of shape by the outer lock core sum and forms, and key is arranged at said outer lock core bottom.
As further improvement of the present invention; Said bullet groove is arranged on internal cylinder one side or is symmetricly set on the internal cylinder both sides; This patent bullet groove can be arranged on internal cylinder one side or both sides; Being set to both sides will increase the difficulty of unblanking greatly, but cost also can increase, and producer needs select according to s own situation.
As further improvement of the present invention, at least 2 bullet groove are arranged on the said internal cylinder, the many more unlocking difficulty of bullet groove number are big more, and producer can select according to lock core length.
As further improvement of the present invention, be provided with 1-6 hoodle in the said bullet groove, producer can be provided with the hoodle of respective numbers according to bullet groove length, and each hoodle length producer can select according to the difference of key shape.
As further improvement of the present invention, said outer lock core is provided with draw-in groove, is provided with the slip stop block in the said draw-in groove, makes that through draw-in groove is spacing each lock core lockset position of coupler is different, promotes unlocking difficulty greatly.
The present invention is through a kind of multilayer lockset of design, and the pellet shot from a slingshot in its each layer lock core is in Different Plane, and after preceding one deck lock core opens; Open back one deck lockset again; Though the front and back lock of key is identical, owing to not knowing should be with that part of pellet shot from a slingshot that backs down of key, the position that therefore can transfer is extremely many; Even professional unlock staff also is difficult to open it fast; So lockset has better safety, and simple in structure only on prior art, the improvement a little of this patent can realize, therefore cheaply is easy to produce.
