[0001] The utility model relates to the technical field of fitness dumbbells, in particular to a fitness dumbbell capable of quickly balancing weights. Background Art

[0002] Dumbbells are an auxiliary equipment for weightlifting and fitness exercises. They are smaller than barbells and are therefore favored by fitness enthusiasts. They are named dumbbells because they are silent during practice. You must choose a suitable weight before practicing with dumbbells. Therefore, many dumbbells can now increase or decrease weights to meet the needs of different people. Persistent practice with dumbbells can modify muscle lines and increase muscle endurance. Raising straight arms forward and lateral raises with dumbbells in hand can exercise the shoulder and chest muscles.

[0003] Most current dumbbells are composed of a center rod, a counterweight and a fixing nut, and the dumbbell counterweight is locked and fixed by the nut;

[0004] When disassembling the existing dumbbells, the nut needs to be twisted off to remove the weights one by one from small to large. This cannot achieve quick disassembly of the dumbbells, which brings inconvenience to people's use and wastes a lot of time on disassembly. The requirement of people for arbitrarily and quickly increasing or decreasing the weights cannot be met. Utility Model Content

[0007] Preferably, the outer wall fixing sleeve of the handle is provided with an anti-slip sleeve, and a side of the anti-slip sleeve away from the handle is provided with a plurality of anti-slip grooves.

[0008] Preferably, the first counterweight block and the second counterweight block together form a counterweight disc, and several of the counterweight discs are of different sizes.

[0009] Preferably, the outer walls of the plurality of disks are movably fitted with the inner walls of the plurality of limit grooves, respectively, and the outer walls of the plurality of connecting rods are movably fitted with the inner walls of the plurality of arc-shaped grooves, respectively.

[0010] Preferably, two connecting rods are fixedly mounted on the outer walls of the plurality of second counterweight blocks, and the outer walls of the plurality of pressure plates are movably fitted with the outer walls of the plurality of second counterweight blocks respectively.

[0011] Preferably, a plurality of the counterweight plates are provided with springs, pressure plates, bolts, connecting rods, discs, arc grooves and limit grooves.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The fast-weighted fitness dumbbell can be used to increase the weight of the dumbbell by putting the arc groove on the disc and the connecting rod, and then squeezing the counterweight disc to move toward the baffle position, and the baffle squeezing the pressure plate to move toward the inside of the groove, so that the disc fits on the second counterweight block, and the counterweight disc is rotated to move the connecting rod along the arc groove, so that the disc enters the limit groove. After the counterweight disc is released, the pressure plate will be driven to move outward under the support of the spring to achieve the effect of support, to achieve the effect of limiting the movement of the connecting rod, and to achieve the effect of quick splicing.

[0014] 2. The fast-weighted fitness dumbbell has an anti-skid cover on the outer wall of the handle to prevent the handle from slipping. Since the dumbbell is heavy, it may injure the fitness personnel if it slips out of the hand. The anti-skid groove can increase the friction to achieve the anti-skid effect.
