Description

Vane type idle running anti-theft lock core and key thereof

Technical field

The utility model belongs to lock technology field, is specially adapted to supporting vane type idle running anti-theft lock core and the keys thereof of general lock body such as door lock, lock.

Background technology

In technique known, lockset commonly used mostly is a cylinder lock, generally is made up of lock body and lock core.Lock body is an executing agency, and lock core is a controlling organization, and lock core has inner core and overcoat.Lock body is when locking states, and tiny cylinder-shaped marble is positioned at inner core and overcoat cooperates the place, slit, and inner core can not be rotated relative to overcoat.And inner core is the element of unlatching of control lock body and locking, and inner core can not rotate and just make lock body keep the state of locking.If when the chance thief adopted the drilling method to destroy inner core, then inner core was easy to destroyed and loses function, and the cross section of pellet shot from a slingshot is little, be easy to wearing and tearing, so can not preventing drilling, conventional lock cylinders destroys, its theftproof performance is low.In addition, be used for the supporting key of cylinder lock and adopt monolithic zigzag key mostly, prepare easily, even dial the twist lock inner core, can unblank with a slice substance.Also have plenty of at the teeth and the gathering sill position of key and take some structural measures, but still have the mutual opening rate height and copy defectives such as easy.

The utility model content

The purpose of this utility model provides and a kind ofly can prevent that drilling from destroying, and improves the lockset theftproof performance, and mutual opening rate is low, and can effectively avoid vane type idle running anti-theft lock core and the key thereof copied.

Realize that the technical scheme that the purpose of this utility model is taked is: be provided with rotating middle cover between the overcoat of this lock core and the inner core, correspondence is provided with blocking key groove on overcoat, middle cover and inner core, block key and outer block key in being equipped with in the blocking key groove, block key elasticity holds out against assembly outside being provided with the blocking key groove corresponding position on the circumferential wall of overcoat, the inside of inner core is provided with blade groove, be laid with axially stacked blade of many groups in the groove, every group of blade is made of positive and negative left and right two blades stacked and that connect by return spring.The key body cross section supporting with lock core is W shape.

Described elasticity holds out against assembly and is made of pellet shot from a slingshot, holddown spring and shutoff.

Described blade adopts rectangle or ellipse, and the centre of blade is provided with center positioning hole, and dual-side is respectively equipped with the groove and the positioning convex that is used to be connected return spring that can cooperate with interior block key,

The external part of cover is the connector equipped with lock body in described.

Vane type idle running anti-theft lock core and key thereof according to such scheme is made have the following advantages:

(1) simple in structure, the utilization of members such as the middle cover in the lock core structure, inner core, key, blade is ingenious.

(2) theftproof performance is good, organizes blade, arrangement scheme is many more, and the period of key is big, and mutual opening rate is low, and unique idle rotation lock master structure makes and bores the lock theft and be difficult for succeeding.

When (3) closing atretic body, only need key is directly extracted, but the blade self-return, and it is more convenient to use.

(4) this lock core functional performance is good, applied widely, can with the supporting use of multiple lock body, be applicable to various door locks and lock.

The specific embodiment

Referring to Fig. 1, Fig. 2, Fig. 3,, vane type idle running anti-theft lock core of the present utility model, comprise overcoat 1, middle cover 2, inner core 3, blade 4, blade groove 5, return spring 6, locked lid rivet 7, locked lid 8, keyhole 9, connector 10, blocking key groove 11, shutoff 12, holddown spring 13, pellet shot from a slingshot 14, pellet shot from a slingshot hole 15, outer block key 16 and interior block key 17, consist of a whole lock core by each member.Wherein, middle cover 2 is installed between overcoat 1 and the inner core 3, and free to rotate, and its external part is the connector 10 equipped with lock body.Correspondence is provided with blocking key groove 11 on overcoat 1, middle cover 2 and inner core 3, and interior block key 17 and outer block key 16 are contained in the blocking key groove 11 successively.On overcoat 1 with outside be provided with on the circumferential wall of blocking key groove 11 corresponding positions outside block key elasticity hold out against assembly, this elasticity holds out against assembly and is made of pellet shot from a slingshot 14, holddown spring 13 and shutoff 12, and is assembled in the pellet shot from a slingshot hole 15 of setting.Be provided with blade groove 5 in inner core 3, be laid with axially stacked blade 4 of many groups in the groove, every group of blade is made of positive and negative left and right two blades stacked and that connect by return spring 6.Blade 4 is a rectangle or oval laminar, its centre is provided with center positioning hole, outer side edges is provided with groove 4-1 and positioning convex 4-2, about two blades forward and reverse be one group, the positioning convex 4-2 of every group of blade front portion is supported by return spring 6 during assembling, and after key injected, the groove 4-1 on the blade 4 formed straight line, when home record key 17 enters groove 4-1, by outer block key 16 locked in cover 2 could locate and unblank.Label 8 is locked lids, is connected with overcoat 1 by locked lid rivet 7.

Referring to Fig. 4, Fig. 5, be the key 18 supporting with lock core, the key body cross section is a W shape, its teeth are the side position that one-sided or bilateral is arranged on key body.

When unblanking, key 18 is inserted in the keyhole 9 of inner core 3, the center positioning hole of blade 4 moves under the effect of key 18 teeth, and the groove 4-1 on it is corresponding with the position of interior block key 17, interior block key 17 holddown spring 13 and pellet shot from a slingshot 14 with outside under the pressure effect of block key 16, sink in the groove 4-1, outer block key 16 is deviate from blocking key groove 11, the binding site of cover 2 and inner core 3 in being in, key 18, middle cover 2 is realized the unlatching of lock body with inner core 3 rotations.

When shutting, only need key 18 is outwards extracted, blade 4 is under the tension of return spring 6, block key 17 is deviate from groove 4-1 in making, and outer block key 16 advanced in the blocking key grooves 11, making it to be arranged in the joint portion of overcoat 1 and cover 2,2 in middle cover is fixedlyed connected with overcoat 1, can not relatively rotate, and reach the purpose that shuts.Meanwhile, interior block key 17 is deviate from inner core 3, and 3 of inner cores can freely dally with respect to middle cover 2, prevent stealer drilling lock core effectively with this, makes it can't reach the purpose of destroying lock core.
