Abstract
The utility model discloses an electronic anti-theft screw. A fastening screw lower body is sleeved with a fastening screw upper body in a coaxial mode, and two pins are used for enabling the fastening screw lower body and the fastening screw upper body to be matched in a rotating mode and not to be separated. An electromagnetic coil and a control circuit board and the fastening screw upper body are fastened into a whole. An armature is arranged in a rotating groove in the fastening screw upper body, and can move up and down in the axial direction of the fastening screw upper body. Due to blocking by the rotating groove in the fastening screw upper body, the armature can not rotate relative to the fastening screw upper body. An electromagnetic coil and an electromagnetic coil drive electronic circuit are integrated in the electromagnetic coil and the control circuit board. The electromagnetic coil and the control circuit board are electrically connected with an external unlocking device through an external unlocking signal and a power source appliance connection terminal. The electronic anti-theft screw has the advantages of being simple in structure, good in theft prevention performance, and practical, and reducing cost.

Embodiment
Now by reference to the accompanying drawings, the utility model embodiment is described in detail in detail:
As shown in Figure 1 and Figure 2, a kind of electronic anti-theft screw, comprise fastening screw upper body 1, electromagnetic coil and control circuit board 3, armature return spring 4, armature 5, lock dog 6, lock dog return spring sheet 7, fastening screw lower body 8, outside unlocking signal and power supply electrical equipment splicing ear 10, outside unlocking signal and power supply electrical equipment splicing ear 10 pass in the fastening screw upper body 1 inner top and are connected with electromagnetic coil and control circuit board 3; Electromagnetic coil and control circuit board 3 are connected in the inner top of fastening screw upper body 1; Fastening screw upper body 1 is provided with rotation slot 11; The top of fastening screw lower body 8 is provided with locked groove 81; The top of fastening screw lower body 8 offers circular groove 82; The lower outside of fastening screw lower body 8 is provided with screw thread 83; Described fastening screw lower body 8 is connected on fastening screw upper body 1, and circular groove 82 is connected with fastening screw upper body 1 by pin 9; Form between fastening screw lower body 8 and fastening screw upper body 1 and rotate chamber 12, armature return spring 4, armature 5, lock dog 6, lock dog return spring sheet 7 are connected in from top to bottom and rotate in chamber 12; Lock dog return spring sheet 7 is positioned on locked groove 81; Armature 5 is positioned on rotation slot 11; Armature return spring 4 in the situation that compression lock dog 6 half be positioned on rotation slot 11; Armature return spring 4 lock dog 6 under normal state is positioned at rotates chamber 12 fully.
Fastening screw of the present utility model upper body 1 coaxial sleeve adopts two pins 9 to make both for being rotatably assorted and can not separating on fastening screw lower body 8.Electromagnetic coil and control circuit board 3 is fastened as a whole with fastening screw upper body 1, armature 5 is arranged in the rotation slot 11 of fastening screw upper body 1, can be along the fastening screw upper body 1 axially move up and down, due to stopping of fastening screw upper body 1 interior rotation slot 11, can not relatively rotate between armature 5 and fastening screw upper body 1.The interior integrated electromagnetic coil of electromagnetic coil and control circuit board 3 and electromagnetic coil drive electronic circuit, by outside unlocking signal and power supply electrical equipment splicing ear 10 and outside unlocking device electric connection of generation.
When not unblanking, outside unlocking signal does not connect external equipment with power supply electrical equipment splicing ear 10, does not have power supply to be added on electromagnetic coil and control circuit board 3.At this moment, the state of 1 inside, fastening screw upper body is: the active force of armature return spring 4 is slightly stronger than the active force of lock dog return spring sheet 7, armature 5 is under the effect of armature return spring 4, and the breach shutoff with on the rotation slot 11 of fastening screw upper body 1 forms a plane; Simultaneously lock dog 6 is pressed in locked groove 81 on fastening screw lower body 8 by armature 5, and both also form a plane; Two interplanars are unobstructed, and are in separated state, and fastening screw lower body 8 is free to rotate.Therefore, when lock body is opened by unauthorized external force, can only drive fastening screw upper body 1 idle running, rotate together and can not drive fastening screw lower body 8, namely can't unblank.
When unblanking, outside unlocking signal is connected with external equipment with power supply electrical equipment splicing ear 10, and electromagnetic coil and control circuit board 3 energisings make the electromagnet fixed core produce magnetic force, this power weakens the active force of armature return spring 4, and lock dog return spring sheet 7 active forces are relatively strong; Under the active force of lock dog return spring sheet 7, lock dog 6 is ejected the locked groove 81 on fastening screw lower body 8, enters on the rotation slot 11 of fastening screw upper body 1, and fastening screw upper body 1 is linked into an integrated entity with fastening screw lower body 8.Fastening screw lower body 8 can be followed fastening screw upper body 1 rotation together at this moment, and lock is opened.
