Abstract

L'invention concerne une étiquette antivol, comprenant un boîtier composé d'un couvercle supérieur et d'une base (2). Un mécanisme de verrouillage de broche antivol est disposé entre le couvercle supérieur (1) et la base (2), une broche antivol est insérée dans le boîtier à partir du couvercle supérieur (1) et est verrouillée et positionnée par le mécanisme de verrouillage; un dispositif de retrait de verrouillage magnétique correspond à et déverrouille un mécanisme de verrouillage à bille en acier, des billes en acier (91, 92) étant enfermées dans des douilles rondes inférieures (1013, 1023) d'éléments oscillants (101, 102); les billes en acier (91, 92) poussent, sous l'action du dispositif de retrait de verrouillage magnétique, les éléments oscillants (101, 102) à basculer vers l'extérieur jusqu'à ce que des griffes convexes (1012, 1022) des éléments oscillants (101, 102) ne poussent plus contre un support de billes de verrouillage (5); et, en même temps, les extrémités inférieures des griffes convexes (1012, 1022) presse un couvercle de ressort (71) et un ressort (7), de telle sorte que le ressort (7) ne pousse plus contre le support de billes de verrouillage (5); et une bille de verrouillage (6) dans le support de billes de verrouillage (5) se déplace vers le bas sous l'attraction magnétique du dispositif de retrait de verrouillage, réalisant ainsi un déverrouillage. L'invention présente une structure simple et est facile à fabriquer. Le mécanisme de verrouillage ne peut pas être déverrouillé en utilisant uniquement une combinaison d'aimants à structure simple. La bille de verrouillage (6) peut uniquement être retirée par un dispositif de retrait de verrouillage magnétique correspondant à la solution décrite, assurant ainsi le déverrouillage sécurisé du mécanisme de verrouillage.
