AI Technical Summary
Existing quick-adjustable dumbbells have a safety hazard because the weight plates can easily fall off when the handle is not properly adjusted.
An adjustable dumbbell was designed. By setting hooks, end cap assemblies and rotating adjustment plates on the base, and using the cooperation of locking plates and elastic elements, the dumbbell is ensured that the handle can only move when it is in the correct position. Otherwise, the base is prevented from moving, thus preventing the dumbbell from falling off.
This improves the safety of dumbbell use, preventing weight plates from falling and injuring the user if not properly adjusted, thus enhancing the reliability and safety of training.
