A snap-in groove 33 is provided on one side of a connecting groove 34, and a snap-in groove is provided on the other side of the first connecting groove 34 and away from the side of the snap-in groove 33, which can facilitate the use of the connecting piece 35, and multiple groups of dumbbell plates 2 have the same structure. Through the setting of the connecting piece 35 and the mounting piece 3, the number of dumbbell plates 2 can be quickly increased, and the dumbbell plates 2 are installed on the outside of the retaining ring 2. The dumbbell plates 2 are hexagonally arranged, which can prevent them from moving around when not in use compared to the traditional circular setting, and a group of dumbbell plates 2 close to the retaining ring 11 is fixedly connected to it, which can facilitate the installation of other dumbbell plates 2.

[0028] The connecting member 35 includes a connecting rod 351 located inside the first connecting groove 34 and the second connecting groove 357. The connecting rod 351 is movably connected to the dumbbell plates 2 and the dumbbell bar 1 through the first connecting groove 34 and the second connecting groove 357, which can facilitate the quick positioning of the dumbbell bar 1 and the dumbbell plates 2 to prevent the dumbbell plates 2 from being unstable. The second connecting grooves 357 are arranged equidistantly, which can facilitate the installation of multiple groups of dumbbell plates 2.

[0029] A screw rod 352 is fixedly connected to the bottom of the connecting rod 351, and a nut 353 is fixedly connected to the inside of the second protective groove 32 and located at the bottom of the dumbbell plate 2. The screw rod 352 extends to the inside of the second protective groove 32 through the first connecting groove 34 and the second connecting groove 357, and is threadedly connected to the nut 353. The top of the connecting rod 351 is located inside the first protective groove 31. The setting of the first protective groove 31 and the second protective groove 32 can make the connecting piece 35 located inside the dumbbell plate 2 to prevent it from extending to the outside of the dumbbell plate 2 to prevent harm to personnel, and can protect the connecting piece 35.

The internal movably sleeve of the connecting block 43 is connected with a bolt 44. The rubber sleeve 41 is elastic and can be directly pried to slowly separate the two ends of the rubber sleeve and sleeved on the surface of the dumbbell bar 1. The rubber sleeve 41 and the rubber strip 42 can increase the friction with the operator, thereby preventing the hand from sweating and causing separation from the dumbbell bar 1, and can increase the comfort of the operator.

[0037] A threaded hole 45 is provided on the surface of the dumbbell bar 1 and located on the inner side of the retaining ring 11 . A bolt 44 extends to the inside of the threaded hole 45 through the connecting block 43 and is threadedly connected thereto, so that the anti-slip member 4 can be easily replaced.

[0038] The rubber sleeve 41 and the rubber strip 42 can increase the friction with the hand, which can help the user hold the dumbbell more firmly and avoid the dumbbell from slipping due to factors such as hand sweat. When replacing the anti-slip part 4, the bolt 44 can be directly removed to complete the operation.

[0039] The remaining structures are the same as those of Example 1.
