AI Technical Summary
Technical Problem
Existing dumbbells have the risk of falling and excessive stress on their wrists when used, which affects training results and wrist health.
Method used
A rotating fast adjustable dumbbell is designed to reduce the pressure on the wrist through the rotation of the sleeve and the bar, and increase the friction between the palm and the dumbbell through deep grooves to avoid sliding and losing hands.
Benefits of technology
Effectively reduces the pressure on the wrist when performing heavy weight training, reduces the risk of wrist strain, and avoids dumbbell sliding and losing hands by increasing friction.

Abstract
The utility model relates to the technical field of dumbbells, and discloses a rotary dumbbell capable of being quickly adjusted, which comprises two connecting ends and a plurality of dumbbell pieces, the two connecting ends are detachably connected through a lifting component, the other ends of the two connecting ends are both provided with second threaded holes, the second threaded holes are internally in threaded connection with screw rods, and the screw rods are connected with the dumbbell pieces. The outer side of the lead screw is sleeved with dumbbell pieces. The sleeve and the polished rod are in a rotating state, so that pressure borne by the wrist is reduced when training actions such as bending lifting, lateral flat lifting and bird drawing are performed under large weight, friction force between the sleeve and the palm is increased through the deep groove lines, the situation that the dumbbell is prone to sliding and slipping out of the hand after the palm sweats is effectively avoided, and the training effect is good. The dumbbell pieces can be quickly hung on the lead screw through the N-shaped hanging grooves, and the risk that an existing dumbbell usually adopts a straight groove bayonet, and consequently the dumbbell falls off can be avoided through the bending design of the N-shaped hanging grooves.
