The specific embodiment
As shown in Figure 1, idle running anti-theft lock core described in the utility model, comprise lock core body 1, be located in the lock core body 1 and with its lock gall 2, the coaxial turning set 3 and that is arranged between lock core body 1 and the lock gall 2 executing agency 4 of stretching out lock core body in relative rotation, described lock gall 2 is provided with the key road that inserts for key, executing agency 4 outer ends with dial the tongue execution unlocking function that is in transmission connection.
Shown in Fig. 1～8, idle running anti-theft lock core described in the utility model also comprise conduction or cut off lock gall 2 to the elasticity clutch 5 of the active force of executing agency 4, and connect or disconnect the elasticity holding mechanism 6 that the interlock of lock gall 2 and turning set 3 is provided with.Described elasticity clutch 5 is built in lock core body 1, be located between lock gall 2 and the executing agency 4, it comprises: be connected and can promote the mobile clutch block 51 along the lock core body axial slip, the flexible member that is driven the clutch power transmission shaft 52 that moves in the same way and the power that resets is provided for mobile clutch block and clutch power transmission shaft by mobile clutch block 51 by it with turning set 3.Wherein, above-mentioned mobile clutch block 51 is the round plate that adapts to turning set 3 sizes, its middle part is provided with the through hole 511 that passes for the clutch power transmission shaft, along holding the projectioies 512 that are provided with two band inclined-planes relatively week, one end of turning set 3 is provided with mobile clutch block projection 512 and adapts to the pit bit 31 that cooperates, when projection 512 when placing in the pit bit 31, mobile clutch block 51 and turning set 3 are near contacting; The both ends of above-mentioned clutch power transmission shaft 52 are respectively the tabular body 521 that slidably inserts lock gall and executing agency, be installed with on it with mobile clutch block 51 against the locating piece 522 that contacts, when clutch power transmission shaft 52 1 ends pass mobile clutch block through hole 511 and are slidingly matched with lock gall 2, locating piece 522 just in time props up through hole 511, therefore can drive clutch power transmission shaft 52 slippage in the same way when mobile clutch block 51 is along the lock core body axial slip, and clutch power transmission shaft 52 clutch block 51 that can relatively move rotates; Above-mentioned flexible member comprises and is respectively first back-moving spring 53 and second back-moving spring 54 that mobile clutch block and clutch power transmission shaft provide the power that resets, first back-moving spring, 53 two ends respectively with mobile clutch block 51 and lock core body 1 contact mutually, second back-moving spring, 54 two ends respectively with clutch power transmission shaft 52 and executing agency 4 contact mutually.Described lock gall 2 and executing agency 4 are respectively equipped with the slideway of pegging graft and cooperating with the tabular body 521 of clutch power transmission shaft, when clutch power transmission shaft 52 places in the slideway of lock gall 2 and executing agency 4 simultaneously, lock gall 2, clutch power transmission shaft 52 and executing agency's 4 linkages, thereby lock gall 2 can be transmitted to active force executing agency 4, carries out unlock operation.
Described elasticity holding mechanism 6 is built in turning set 3, be located between lock gall 2 and the turning set 3, it comprises: axially be provided with and be set in holding piece 62 on the fixed axis and the torsion spring 63 that is connected with holding piece corresponding matching with fixedly connected fixed axis 61, the plurality of movable of lock gall 2 along lock core body 1.Wherein, above-mentioned holding piece 62 is in lock gall left and right sides arranged distribution, each holding piece 62 is respectively equipped with first projection 621 and second projection 623 that is linked with turning set 3, and the internal face of turning set 3 is respectively equipped with last draw-in groove position 32, left draw-in groove position 33 and the right draw-in groove position 34 that cooperates and can supply projection to snap in the adaptation of holding piece projection.
Operating principle of the present utility model is as described below:
Shown in Fig. 1,9a, when lock core was in the nature lock-out state, second projection 622 of elasticity holding mechanism holding piece 62 snapped in the left and right draw-in groove position 33,34 of turning set 3 respectively automatically under the torsion spring effect.And when the lower non-matching key of tooth depth inserts lock gall key road, the tooth of non-matching key can't touch holding piece 62, the 62 no external force effects of holding this moment piece, its second projection 622 still places in the draw-in groove position, the left and right sides 33,34 of turning set, if the rotation non-matching key will drive lock gall 2, elasticity holding mechanism and turning set 3 and rotate simultaneously; And when turning set 3 rotates, the projection of the pit bit of turning set 3 and mobile clutch block 51 will misplace, mobile clutch block 51 compressions first back-moving spring 53 is along the lock core body axial slip, driving clutch power transmission shaft 52 compressions second back-moving spring 54 moves in the same way, at this moment, the tabular body of clutch power transmission shaft 52 1 ends slides into toward executing agency 4 slideway depths, the tabular body of the other end then withdraws from lock gall 2, therefore, lock gall 2 disconnects with executing agency 4 and being connected, and lock gall 2 can't conduct active force to executing agency 4, can't drive executing agency 4 and rotate, lock gall 2 and turning set 3 can only dally, and can't open lock core.
Shown in Fig. 1,9b, when the higher non-matching key of tooth depth inserts lock gall key road, the tooth of non-matching key will push up holding piece 62, forcing holding piece 62 to overcome torsion spring active force generation wide-angle rotates, first projection 621 of holding this moment piece 62 will snap in the last draw-in groove position 32 of turning set 3, if rotate non-matching key, and will be with above-mentioned the same, lock gall 2 and turning set 3 dally, and can't open lock core equally.
As Fig. 1, shown in the 9c, when inserting matched key, the key tooth depth is just right, holding this moment piece 62 takes place to rotate by a small margin under the key effect, first projection 621 and second projection 622 withdraw from the draw-in groove position of turning set 3 simultaneously, if key, to drive lock gall 2 rotates and can not drive turning set 3 and rotate simultaneously, at this moment, slippage can not take place in mobile clutch block 51 no external force effects, and clutch power transmission shaft 52 two ends place respectively in lock gall 2 and executing agency's 4 slideways, therefore, lock gall 2 will conduct active force to executing agency 4 and drive executing agency 4 and rotate by clutch power transmission shaft 52, thereby realize unblanking.
The utility model is not limited to above-mentioned embodiment, if various changes of the present utility model or modification are not broken away from spirit and scope of the present utility model, if these are changed and modification belongs within claim of the present utility model and the equivalent technologies scope, then the utility model also is intended to comprise these changes and modification.
