Abstract

L'invention concerne un barillet de serrure antivol et incrochetable, adapté pour être utilisé dans toutes les serrures commandées par rotation du barillet de serrure. L'invention est basée sur une structure relevant de l'état connu de la technique, et est caractérisée en ce qu'une pièce non circulaire, limitant la position, est prévue entre une enveloppe cylindrique et un pêne dormant, en ce qu'un bloc de limite, connecté à ladite pièce limitant la position, limite efficacement la rotation du pêne dormant lorsque la clé n'est pas insérée dans la serrure ; en ce qu'une fente supplémentaire pour les tiges ou les pênes dormants plats est prévue dans la direction axiale ou dans la direction radiale de la fente pour les tiges ou les pênes plats dans l'enveloppe cylindrique, le pêne dormant peut être limité plusieurs fois, de sorte qu'il est plus difficile de déverrouiller la serrure par une clé universelle, et le barillet de serrure lui-même ne peut être débloqué par une clé universelle. Non seulement la structure du barillet de serrure incrochetable et antivol est simple et rationnelle, la technique de construction dudit barillet est simple, la production est facile et d'un faible coût, mais le dispositif selon l'invention est incrochetable, et ne peut être brisé par torsion et déverrouillé illégalement. Le dispositif est adapté pour être utilisé principalement comme moyen de dissuasion antivol pour portes, coffres-forts, motocyclettes, automobiles, mais peut également être fabriqué pour des verrouillage de chaînes, serrures de type papillon, serrures de type en « U », cadenas, etc
