Abstract

La présente invention concerne une manille pour empêcher un boulon d'être desserré par une rotation inverse, et plus spécifiquement, une manille pour empêcher un boulon d'être desserré par une rotation inverse, laquelle manille peut empêcher un objet lourd de tomber en raison de la séparation du boulon à partir d'un corps principal de manille par une rotation inverse, qui est provoquée par une vibration continue ou un impact externe quand un treuil lève l'objet lourd, par l'installation et l'utilisation d'un dispositif de commande de rotation qui empêche la rotation inverse du boulon. La manille pour empêcher un boulon d'être desserré par une rotation inverse selon la présente invention comprend : un corps principal de manille ayant des trous d'insertion formés dans des côtés opposés de ce dernier ; un boulon inséré dans les trous d'insertion qui sont formés dans le corps principal de manille ; et un dispositif de commande de rotation qui est couplé de manière fixe à l'extérieur du corps principal de manille et qui restreint de façon sélective la direction de rotation dans laquelle le boulon est tourné par une force externe.
