Abstract

L'invention concerne une barre à disques pratique sans démontage, comprenant une barre de barre à disques et deux disques de barre à disques. La barre de barre à disques comprend une section de liaison droite (13-1) et des sections de support de disque situées des deux côtés de la section de liaison droite (13-1). Chaque section de support de disque est utilisée pour monter l'un des disques de barre à disques, et comprend une section de barre droite (13-3) et une section de sous-chaîne (13-2), la section de sous-chaîne (13-2) étant située entre la section de liaison droite (13-1) et la section de barre droite (13-3), et étant reliée de manière articulée à la section de liaison droite (13-1) et à la section de barre droite (13-3) séparément. Selon la barre à disques, des barres droites et des barres incurvées sont combinées parfaitement, ce qui permet de réduire l'utilisation de matières premières, permettant aux barres d'être remplacées librement, d'éviter les problèmes, et de rendre la barre à disques plus commode à transporter. De plus, étant donné que les bases de disques de barre à disques intégrées sont structurées de manière simple, après que les bases de disques de barre à disques intégrées sont installées, et lorsqu'il est nécessaire d'ajouter des poids à la barre à disques, le démontage et l'installation répétés ne sont pas nécessaires, et l'ajout de poids peut être mis en œuvre uniquement par coulissement doux d'un bloc coulissant dans une fente coulissante.
