摘要： The present invention discloses a weight-adjustable dumbbell component with a locking mechanism, comprising a dumbbell component, a dumbbell seat and a plurality of dumbbell pieces placed at two sides of the dumbbell seat. The dumbbell seat comprises a handle component, tailstock components disposed at two sides of the handle component and two sliders movably connected to two ends of the handle component. Rotating the handle component can drive the sliders to move slidably in a rotation stopping groove. By disposing a guiding groove inside a handle tube, a guiding block at one end of one of the sliders is mounted inside the guiding groove and the guiding groove inside the handle tube can pull the one of the sliders to move leftward or rightward.
