Technical Field
[0001] This utility model relates to the field of dumbbell technology, and in particular to a novel electroplated handle pot-shaped dumbbell. Background Technology
[0002] With the improvement of living standards, people are paying more and more attention to the quality of life and health. Fitness has become the first choice for most people to exercise, and kettlebells are one of the most common fitness equipment. Existing kettlebells are mostly made of cast iron for both the handle and the dumbbell body. Since cast iron cannot be welded together, existing kettlebells are all made by one-piece casting. Cast iron has low strength and is easily damaged. Furthermore, the surface of cast iron cannot be electroplated, so the handles of existing kettlebells are painted. However, painted handles are more prone to rust and have an unattractive appearance. Therefore, a new type of kettlebell with an electroplated handle is proposed. Utility Model Content
