Electrically-adjustable dumbbell

Abstract

The present disclosure relates to an electrically-adjustable dumbbell, comprising a handle part, wherein installation parts connected to the handle part are respectively arranged at the two sides of the handle part, and the outer sides of the installation parts are used to be connected to dumbbell plates; the central part of the handle part is an axially through channel, and an adjusting mechanism in fit with the inner wall of the channel in shape is arranged in the channel. The dumbbell provided by the present disclosure is reasonable in structural design, electric adjustment of the dumbbell is achieved by using the adjusting mechanism composed of the motor, the threaded rod and the limiting plates, the adjusting process can be achieved only by manually operating a control circuit board, manual adjustment of the dumbbell plates is not needed, operation is convenient, and the user experience effect is improved.
