Abstract

The utility model relates to an idling lock core which comprises a housing and a core body connected with the housing by the rotating way. A plurality of blades are arranged in the core body, the side wall of the core body is provided with a longitudinal through groove, a control strip and a compression spring are arranged in the through groove, the edge at the inner side of the control strip is mostly smooth, a small fraction of the edge is provided with corner angles, and the edge of each blade is also provided with a gap which matches with the edge of the control strip, wherein a gap on the blade matching with the edge of the control strip with corner angles is also provided with corner angles, and the gaps of the rest blades are all smooth. The structure of the lock core is reasonable, the gap of each blade is staggered under the normal condition, a non-original key or deformed tool is inserted to only twist each blade to idle, the core body can not be driven, the intensifying torsion unlocking is avoided, and the burglary prevention property is good.

Description

Idle-run lock pin

Technical field: the utility model relates to a kind of lock core.

Background technology: the blade of general lock core the inside when common state all and core body maintenance cooperation, blade can not dally, the insertion key can twist core body and unblank, and is easy to like this utilize twist blade by force and then drive core body in the instrument insertion keyhole unblank, and theftproof performance is reliable inadequately.

Summary of the invention: at the deficiencies in the prior art, it is a kind of rational in infrastructure that the utility model provides, and prevents the idle-run lock pin of turning round by force.

The utility model comprises shell and the core body that is rotationally connected, core body is built-in with the multi-disc blade, the core body sidewall is provided with groove longitudinally, control strip and compression spring place groove, the edge major part of this control strip inboard is smooth, and fraction is provided with corner angle, and the edge of each blade also is equipped with the edge mate of breach and control strip, wherein the corresponding matching control strip has the corresponding corner angle that also are provided with of breach on the angular edge blade partly, and the breach on the rest blade is all smooth.

Of the present utility model rational in infrastructure, the breach of each blade all staggers at common state, inserts non-original key or profile tool and only can twist each lamina idle-run, can't drive core body, avoids turning on by force lock, and theftproof performance is good.

Further specify the utility model below in conjunction with drawings and Examples.

Figure 10 is the E-E sectional drawing of Fig. 9.

Embodiment 1: to shown in Figure 5, shell 1 and core body 2 are rotationally connected as Fig. 1, and core body 2 is built-in with multi-disc blade 3.Core body 2 sidewalls are provided with groove 4 longitudinally, and control strip 5 and compression spring 6 place groove 4, and the edge major part of these control strip 5 inboards is smooth, and fraction is provided with corner angle.The edge of each blade 3 also is equipped with the edge mate of breach 7 and control strip 5, and wherein corresponding matching control strip 5 has the breach 7 corresponding corner angle that also are provided with on the angular edge blade 3 partly, and the breach 7 on the rest blade 3 is all smooth.

When tool using inserted, the breach 7 on each blade 3 can't correctly be arranged in a straight line, and the edge of control strip 5 also can't enter in the breach 7 and blade 3 engagings, even also just idle running of twisting blade 3 like this can't drive core body 2 and unblank.The edge that common control strip 5 is provided with corner angle is positioned at the stage casing, the blade 3 of corresponding band corner angle breach 7 also is positioned at core body 2 middle parts, even there is the breach 7 of indivedual blades 3 of entrance to be rotated and control strip 5 edge correspondence positions like this, also only be that control strip 5 one ends engage indivedual blades 3, reverse by force when moving because breach 7 and control strip 5 edges are all smooth, the meeting skid, high safety.

When inserting the original key rotation, extremely shown in Figure 8 as Fig. 6, the breach 7 of each blade 3 correctly is arranged in a straight line, control strip 5 moves under the effect of compression spring 6, the edge moves in the breach 7, the position that includes corner angle also is snapped in the breach 7 that corner angle should be arranged mutually, and like this during moving blade 3, control strip 5 is unblanked by twisting together with core body 2.

Embodiment 2: as Fig. 9 and shown in Figure 10, also be equipped with thin circular shaft 8 in the groove 4, thin circular shaft 8 is positioned at the smooth edge part of the alternative control strip 5 in inboard of control strip 5, and all the other are with embodiment 1.The edge that common control strip 5 is provided with corner angle is positioned at the stage casing, and thin circular shaft 8 generally also is upper and lower two.

The area of control strip 5 can dwindle during manufacturing, and smooth edge is equal to alternative by thin circular shaft 8, and process and assemble is all more convenient.When unblanking with instrument, blade 3 dallies equally.When inserting key, establish the corner angle part in the middle of the edge of control strip 5 and can snap in the breach 7 of corresponding blade 3, can unblank.
