Abstract
The invention discloses an electronic anti-theft screw. A fastening screw upper body is sleeved on a fastening screw lower body in a coaxial mode, and the fastening screw upper body and the fastening screw lower body are matched in a rotation mode and can not be separated. An electromagnetic coil and a control circuit board are fastened with the fastening screw upper body integrally. An armature is arranged in a rotating groove of the fastening screw upper body and can move vertically along the axial direction of the fastening screw upper body. Due to blocking of the rotating groove in the fastening screw upper body, the armature can not rotate relative to the fastening screw upper body. The electromagnetic coil and an electromagnetic coil driving electronic circuit are integrated in the electromagnetic coil and the control circuit board so that the electromagnetic coil and the control circuit board can be electrically connected with an external unlocking device through an external locking signal and a power supply electric appliance connecting terminal. The electronic anti-theft screw has the advantage of being simple in structure, good in anti-theft performance, cost-saving and practical.

Embodiment
Now by reference to the accompanying drawings, the specific embodiment of the invention 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 passes in the inner top of fastening screw upper body 1 with power supply electrical equipment splicing ear 10 and is 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 following outside of fastening screw lower body 8 is provided with screw thread 83; Described fastening screw lower body 8 is connected on the 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 the 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 the chamber 12; Lock dog return spring sheet 7 is positioned on the locked groove 81; Armature 5 is positioned on the rotation slot 11; Armature return spring 4 under the situation of compression lock dog 6 half be positioned on the rotation slot 11; Armature return spring 4 lock dog 6 under normal state is positioned at fully and rotates chamber 12.
Fastening screw of the present invention upper body 1 coaxial being enclosed within on the fastening screw lower body 8 adopts two pins 9 to make the two for being rotatably assorted and can not separating.Electromagnetic coil and control circuit board 3 fasten as one with fastening screw upper body 1, armature 5 is installed in the rotation slot 11 of fastening screw upper body 1, can axially moving up and down along fastening screw upper body 1, owing to stopping of fastening screw upper body 1 interior rotation slot 11, can not relatively rotate between armature 5 and the fastening screw upper body 1.Integrated electromagnetic coil and electromagnetic coil driving electronic circuit produce electric connect with power supply electrical equipment splicing ear 10 with outside unlocking device by outside unlocking signal in electromagnetic coil and the control circuit board 3.
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 the 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 with the breach shutoff on the rotation slot 11 of fastening screw upper body 1, forms a plane under the effect of armature return spring 4; Simultaneously lock dog 6 is pressed in the locked groove 81 on the 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 1 idle running of fastening screw upper body, 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 is with the active force reduction of armature return spring 4, and lock dog return spring sheet 7 active forces are stronger relatively; Under the active force of lock dog return spring sheet 7, lock dog 6 is ejected the locked groove 81 on the fastening screw lower body 8, enters on the rotation slot 11 of fastening screw upper body 1, and fastening screw upper body 1 and fastening screw lower body 8 are linked into an integrated entity.Fastening screw lower body 8 can be followed fastening screw upper body 1 and rotated together this moment, and lock is opened.
