Technical Field

[0001] This utility model relates to the field of dumbbell equipment technology, and more specifically to a dumbbell with an adjustable dumbbell disc. Background Technology

[0002] Dumbbells are one of the most basic, practical, and extremely powerful training tools in the fitness field. They are highly efficient, flexible, and practical training tools and an indispensable part of any fitness plan. However, existing dumbbell equipment still has the following shortcomings in actual use; First, in the use of existing dumbbell equipment, in order to adjust the number of dumbbell discs, the length of the shaft section where the dumbbell discs are placed is increased. In order to better fix the dumbbell discs, the length of the threaded groove opened in the shaft section is also increased, and the length that the locking nut needs to be screwed in also increases. This makes the operation of locking the nut when adjusting the number of dumbbell discs quite cumbersome. Secondly, when placing dumbbells with existing technology, if there are many dumbbells and the dumbbell equipment is heavy, the dumbbells are prone to colliding with the ground, which can damage the dumbbell plate and the ground. Existing dumbbell equipment does not have a protective function. Therefore, in order to solve the above problems, there is a need to provide a dumbbell with an adjustable dumbbell disc.
