The intracavity bottom of the shell 7 of said lockset, the outer step surface 1b position with the bottom of lock core shell 1 is provided with is provided with identification code 9.

When using the lockset work of the utility model unlock key:

The implementation of theftproof, like Fig. 1, Fig. 2, Fig. 3, Figure 17, Figure 18, before key inserted, lock pin 3 spring 4 that is reset was pressed on the interior step surface 1d of lock core shell 1, and lock pin 3 side discs are extruded into steel ball 6 to be changeed between core 2 and the lock core shell 1, and this moment, lock core can't rotate; After key inserts; Six step surfaces at key top can be risen annular recess 3a on the lock pin 3 over against the steel ball position with six lock pins 3 in the lock core, this moment rotational lock core, steel ball 6 is under the squeezing action of lock core shell; Move in the annular recess 3a of lock pin 3, lock core can rotate and unblank.

After the implementation of way to manage, key were inserted and had the lockset of identification code 9, the key top had the step surface of six differing heights that the lock pin in the lock core 3 is pushed up the lock core unlocked position; But because key end has a moving pin 81 to be clipped between fixed lock core shell 1 and the rotary key bit, if moving pin 81 does not move, key can't rotate; Lockset just can't be opened, like Figure 14. and after key inserted lockset, the step surface at key top was risen unlocked position with lock pin 3; Simultaneously; The moving pin 81 of end is inserted among the semicircle stepped hole 1c of lock core shell 1 on the key, if key reads the information less than the identification code 9 of lockset, the mechanism in the key bit stops moving of moving pin 81; This moment, moving pin 81 was stuck between lock core shell 1 and the release mechanism 8, and key can't rotate; If key reads the information of lockset identification code 9, the key bit internal mechanism can discharge the stopping of moving pin 81, this moment key, moving pin 81 is squeezed into release mechanism 8 inside, unblanks thereby can rotate.

Like Figure 11,12,13; In the time of in this unlock key inserts lockset, the lock pin that release mechanism 8 promotes in the lock core arrives the lock core unlocked position, because moving pin 81 is withstood (like Figure 14) by solenoid plunger 89; Cause moving pin 81 not move backward; So, just be stuck between fixed lock core shell 1 and the rotating key release mechanism 8, cause key to rotate.After key inserted lockset, reading terminal 85 read the information in the identification code 9 on the lockset, and reading terminal 85 is delivered to the information that reads on the control circuit 11 in the CPU; CPU opens the power switch on the CPU after analyzing correctly, gives solenoid 86 energisings; The downward magnetic force of solenoid 86 inner generations after the energising pulls down solenoid plunger 89 downwards, with groove 813 disengagings on the moving pin 81; Compress solenoid back-moving spring 87 simultaneously, CPU detects the current stabilization through solenoid 86, but sends unlock command through the buzzer that is installed on the control circuit; At this moment, key, moving pin 81 is moving in trip lever 82 under the extruding force of lock core shell; Compress moving pin back-moving spring 84 (like Figure 12) simultaneously, open up to lockset.Stir pin 88 in the insertion process and be inserted in the lockset along the open slot 1a on the lock core shell, in the rotation process, stir pin 88 and leave open slot 1a, and on lock core shell inner plane 1d, move, key can't spin off from lock core in the whole process of unblanking.

After lockset was opened, key circled round, and when stirring pin 88 and turn to lock core shell open slot 1a place, key is extracted, and moving pin 81 is moving outside trip lever 82 under the thrust of moving pin back-moving spring 84, and last limited pin 83 blocks; Reading terminal 85 can't read lockset information simultaneously; And this information is delivered on the CPU of control circuit 11; The CPU disconnecting power switch, solenoid 86 loses the power supply supply, and solenoid plunger 89 is moved upwards up in the groove 813 of moving pin 81 under the elastic force effect of solenoid spring 87.Thereby stop moving backward of moving pin 81 once more.

Like Figure 14,15, the part that this key is crucial also is that the part of embodiment way to manage is exactly a release mechanism, and this mechanism has a trip lever; The top has six highly different cylinder steps, and this step effect is the same with common key, realizes release through the height difference; Reveal the pin of stirring outside the trip lever after having one to be positioned at trip lever top and installation; Be hidden into inner spacer pin after having one to be positioned at trip lever top and installation; There is one to be positioned at trip lever first half blind hole and transportable moving pin; Moving pin has a back-moving spring at the back, after moving pin is pressed into blind hole, can moving pin be released; Below in the release mechanism solenoid is installed, solenoid plunger is inserted in the groove below the moving pin through the hole on the trip lever.With the supporting lockset of this unlock key, a lock core is arranged in this lockset, this lock core is made up of a lock core shell, six lock pins etc., has an open slot on the lock core shell, and the pin of stirring in the unlocking structure inserts in the lock core through this open slot; There is an interior step surface lock core shell inside, and when stirring that pin inserts and rotation is unblanked, it is exactly mobile on interior step surface stirring pin, places key simultaneously and extracts midway; Lock core shell bottom also has a capacitor 1f, and this capacitor 1f cooperates with moving pin on the release mechanism, if moving pin can not move backward, causes moving pin to be squeezed between fixed lock core shell and the rotary key, causes key not rotate.Simultaneously, be provided with a lockset identification code with lock core below the lockset, the information of this identification code can be read by the key reading terminal.

Above-mentioned listed concrete implementation is nonrestrictive, and to one skilled in the art, in not departing from the utility model scope, various improvement and the variation carried out all belong to the protection domain of the utility model.
