A dumbbell that prevents the dumbbell from rotating

Abstract

The invention discloses a dumbbell capable of preventing dumbbell discs to rotate. The dumbbell comprises a dumbbell rod and the dumbbell discs. The dumbbell discs are fixedly installed on the inner sides of the two ends of the dumbbell rod through limiting sleeve discs, and the dumbbell discs are isolated and limited through a bolt bar, the bolt bar penetrates through threaded hole in the dumbbell rod and the limiting sleeve discs to be connected with a limiting nut, the two ends of the limiting sleeve disc are each provided with a dumbbell rod stop piece and a nut lantern ring plate respectively, a grip cover is installed between the dumbbell rod stop pieces on the left and right sides, a plurality of sweat absorption groove holes are formed in the outer side of the grip cover, the dumbbell rod is of a cylindrical structure with spiral joints at the two ends, limiting pin shafts are symmetrically installed at the two ends of the dumbbell rod, rotation of the dumbbell discs is greatly avoided, and the use safety of a user is improved.

Description

technical field [0001] The invention relates to the field of fitness equipment, in particular to a dumbbell that prevents the rotation of the dumbbell disc. Background technique [0002] With the improvement of living standards, people pay more and more attention to the beauty of health and body shape, so the investment in bodybuilding is also increasing day by day.
