[0015] Compared with the prior art, the utility model provides a dumbbell with adjustable weight, which has the following beneficial effects:

[0016] 1. Take the counterweight block that needs to be counterweighted and put it through the connecting rod into the adjusting frame so that it contacts the pressure support plate inside the adjusting frame and squeezes the four springs. At the same time, a pressure support plate is placed between adjacent counterweight blocks to prevent the counterweight blocks from colliding with each other and being damaged. The four springs and the pressure support plate inside the frame cover press against the counterweight block at the other end of the adjusting frame so that the frame cover is clamped on one side of the adjusting frame. Then tighten the threaded top block and one end of the connecting rod to achieve the matching of counterweight blocks of different weights inside the adjusting frame and improve the scope of application.

[0017] 2. By movably clamping two absorbent cotton pads on the hand grip rings, and then the user holds the two hand grip rings with both hands, when the hands sweat, they will be absorbed by the absorbent cotton pads, which is convenient for disassembly and replacement of the absorbent cotton pads. At the same time, a number of anti-slip protrusions are convenient for increasing the friction force on the user's hands to prevent the utility model from slipping and causing harm to the user.

[0026] like Figure 1-5 As shown, the utility model provides a dumbbell with adjustable weight, including a barbell bar 1;

[0027] like Figure 1-4 As shown, both ends of the barbell rod 1 are fixed with counterweight assemblies 3, which are convenient for users to adjust the appropriate lifting weight according to their needs. The counterweight assembly 3 includes an adjustment frame 31, which is threadedly connected to one end of the barbell rod 1, and a connecting rod 32 is fixedly provided on the inner side wall of the adjustment frame 31. The end of the adjustment frame 31 away from the barbell rod 1 is covered with a frame cover 33, and a number of counterweight blocks 35 of different weights are sleeved on the connecting rod 32, and buffer pads 36 are provided between adjacent counterweight blocks 35, and the buffer pads 36 are sleeved on the connecting rod 32.

[0028] The screw threaded top block 34 is screwed on one end of the connecting rod 32 away from the barbell bar 1, and the screw threaded top block 34 is tightly attached to one side of the frame cover 33, so as to facilitate tightening the screw threaded top block 34 to fix the position of the frame cover 33 and the adjustment frame 31. Four evenly distributed springs 37 are fixedly provided on one side wall of the inner side of the adjustment frame 31 and one side wall of the frame cover 33. One end of the four springs 37 is fixedly provided with the same pressing support plate 38, so as to facilitate the pressing support plate 38 to squeeze the springs 37 to fix the positions of the plurality of counterweights 35 and prevent the plurality of counterweights 35 from sliding on the connecting rod 32. The plurality of springs 37 and the pressing support plates 38 are all arranged inside the adjustment frame 31. A rubber sleeve 39 is movably provided on the outer wall of the adjustment frame 31 to prevent the utility model from falling. The rubber sleeve 39 increases the buffering force to avoid injury to the user.
