CN2277442Y - Lock tumbler preventing opening with many keys - Google Patents

Abstract

The utility model provides a lock tumbler preventing opening with a plurality of keys. On the basis of the structure of a tradition lock cylinder, an outer lock cylinder of the utility model seals the axial end of the inner lock cylinder whose axial end is provided with a marble hole. The outer lock cylinder is correspondingly provided with a marble channel in which front and back marbles and a spring are provided to match with the teeth on the end face of the key. A pulling slice is extracted out from the side of the inner lock cylinder along the radical direction. Such a marble two-dimensional layout structure makes the combining numbers of the teeth of the key increase greatly, which can not only prevent a universal key with a comb, but also prevent the lock from being opened by a plurality of keys. The utility model has the advantages of simple structure, high insurance performance and strong universality.

Description

A kind of lock core of anti-many spoons of runins

The utility model relates to the field of lock cylinder, particularly the lock core structure of anti-many key runins.

Traditional lock cylinder divides inside and outside two-layer, internal cylinder is placed in the outer lock core, have on the outer lock core that correspondence has the pellet shot from a slingshot hole on bullet groove, the internal cylinder, upper strata pellet shot from a slingshot and lower floor's pellet shot from a slingshot and spring are loaded in above-mentioned bullet groove, the pellet shot from a slingshot hole, after original key inserts internal cylinder, the upper strata pellet shot from a slingshot enters in the bullet groove fully, lower floor's pellet shot from a slingshot is in the pellet shot from a slingshot hole fully, internal cylinder can be rotated relative to outer lock core, thereby will lock unlatching; Otherwise non-original key inserts, and pellet shot from a slingshot is between the inside and outside lock core, and inside and outside lock core is blocked, and they can not be relatively rotated.But because the tartar of key makes up about more than 100 groups, as long as therefore more than the 100 different key of tartar combination arranged, insert the lock core runin one by one, having a key can be with the lock core runin.Perhaps with the omnipotent spoon of broach shape all pellets shot from a slingshot are all pushed bullet groove, making in the pellet shot from a slingshot hole does not have pellet shot from a slingshot, thereby will lock runin.For making lockset prevent runin, people have found out many kinds of structures, design, but notice generally concentrates on spoon face tartar and corresponding bullet groove thereof, the pellet shot from a slingshot, makes the anti-runin ability of lock core can not get effective improvement; Though what have is effective, cost is extremely expensive, and structure is too complicated.

The purpose of this utility model is to overcome the deficiencies in the prior art part, and a kind of many, anti-many keys runin ability lock cores strong, simple in structure of tartar number of combinations that make are provided.

The purpose of this utility model is achieved by the following technical solution: a kind of lock core of anti-many spoons of runins, include outer lock core, be set in the outer lock core and relatively turnable internal cylinder, outer lock core radially has a plurality of bullet groove, internal cylinder radially correspondence has the pellet shot from a slingshot hole, the upper strata pellet shot from a slingshot, lower floor's pellet shot from a slingshot and spring all are loaded in the above-mentioned slotted eye, special feature is that outer lock core also seals the internal cylinder axial end portion, the internal cylinder axial end portion has the pellet shot from a slingshot hole, the outer lock core correspondence has bullet groove, the pellet shot from a slingshot hole, preceding pellet shot from a slingshot is housed in the bullet groove, back pellet shot from a slingshot, spring, back pellet shot from a slingshot cooperates with the tartar of key end face, plectrum then from internal cylinder radially side draw.

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

Below in conjunction with drawings and Examples structure of the present utility model and advantage are further set forth.

Present embodiment still keeps the structure of traditional lock cylinder, internal cylinder 2 is placed in the outer lock core 1, outer lock core 1 radially has five row's bullet groove 3, five pellet shot from a slingshot holes 4 on this bullet groove 3 and the internal cylinder 2 are docked and connected, the lower floor pellet shot from a slingshot 6 corresponding with key 13 upper surface tartars is loaded in the pellet shot from a slingshot hole 4, and upper strata pellet shot from a slingshot 5 and spring 7 are loaded in the bullet groove 3.The end of internal cylinder 2 does not but resemble and is communicated with plectrum 14 traditional structure, but sealed by outer lock core 1, and internal cylinder 2 axial end portions also have two row's pellet shot from a slingshot holes 8, and outer lock core 1 correspondence has two row's bullet groove 9, in be equipped with before pellet shot from a slingshot 10, back pellet shot from a slingshot 11 and spring 12, and back pellet shot from a slingshot 11 cooperates with the tartar of key 13 end faces, and the pinion 15 that 14 of plectrums are radially installed transmission by internal cylinder 2 ends is drawn.The structure of pellet shot from a slingshot two-dimensional arrangement like this, have only original key to insert internal cylinder 2, can be with upper and lower layer pellet shot from a slingshot 5,6, forward and backward pellet shot from a slingshot 10,11 is pushed into lockset position of coupler and does not hinder the rotation of internal cylinder 2, thereby driving plectrum 14 by pinion 15 opens lockset, otherwise,, just lockset can not be opened as long as there is a pellet shot from a slingshot to be stuck between the inside and outside lock core.For the omnipotent spoon of anti-broach shape pushes all lower floor's pellets shot from a slingshot 6 or back pellet shot from a slingshot 11 in the bullet groove fully, the broach shape is linked stub 16 to be inserted in each bullet groove 3,9 from the rear portion, can not be pushed into bullet groove 3,9 fully when making all pellets shot from a slingshot meet omnipotent spoon, play the effect that bullet groove is sealed simultaneously.

Such design, advantage are obvious:

1, set up the pellet of internal cylinder end, structure that need only key is improved a little, just can make the key tooth The flower number of combinations increases greatly, reaches to thousands of kinds;

2, arranging of pellet shot from a slingshot is two-dimensional structure, and the omnipotent spoon of broach can only be opened the pellet shot from a slingshot of one dimension, and is then inoperative to another dimension, and anti-omnipotent spoon ability improves greatly;

3, because the number of combinations of pellet shot from a slingshot, tartar increases greatly, the key runin is impossible basically one by one, the safety performance height;

4, thereby the length of testing lower floor's pellet shot from a slingshot with thin hook is joined the method for unlocking of spoon, the utility model can effectively prevent equally;

5, compact conformation is simple, and is little to the change of conventional lock cylinders and key, highly versatile.
