Card slot snap-fit, while fixture block 412 of locking is moved to snap-fit between locked groove 311 and cooperation closing piece 312, that is, realizes
Locking of the locking fixture block 412 to lock pillar, finally, single-chip microcontroller controls electromagnet power loss, telescopic shaft is multiple under limit spring effect
Position to carry out clamping or limit to unlock rack gear 410, that is, is locked.
The configuration achieves the synchronizing unlocking of label card and case lid, so that it is more convenient to use, and can letter
Change structure, reduces manufacturing cost.
The identification information of built-in guard box in the label card chip, similar to the two dimensional code of existing package, but due to
With material object, thus, there is no random puppets to bring up the case where the tracking that can out-trick.And electronic tag is in the case where unauthorized
(electromagnet does not drive telescopic shaft to bounce back) can not substantially unlock, and therefore, safety is higher, it is only necessary in terminal control
The permission of the terminal device of instruction can be sent to single-chip microcontroller.Certainly, this case needs also to need if higher safety
Preferable encrypted transmission technology, the encryption communication technology of existing bank card or bus card can be directly used in this, to prevent
Label chip is arbitrarily read and write and causes security risk.
Place is not described in detail by the present invention, is the well-known technique of those skilled in the art.
The preferred embodiment of the present invention has been described in detail above.It should be appreciated that those skilled in the art without
It needs creative work according to the present invention can conceive and makes many modifications and variations.Therefore, all technologies in the art
Personnel are available by logical analysis, reasoning, or a limited experiment on the basis of existing technology under this invention's idea
Technical solution, all should be within the scope of protection determined by the claims.
