Electronically controlled adjustable dumbbell

Abstract

The invention discloses an electronically controlled adjustable dumbbell comprising a handle grip, a weight stack, a base, an end cover, an electronic control system and a weight stack locking structure, wherein the weight stack is located below the handle grip. The invention solves the existing problems of adjustable dumbbells as follows: firstly, the operation is so complicated and cumbersome that it is quite difficult to adjust the weight in one try, and the novice who is new to the adjustable dumbbells cannot quickly adjust the weight plate; secondly, visually the product looks too complicated since the number that needs to be adjusted is printed on the cylindrical surface, and half of the numbers on the handle surface are located below the handle grip, which is difficult to see by the user; thirdly, the lack of modernity and inadequate aesthetics hinders product sales and makes it difficult to make profit quickly.
