[0002] Dumbbells are generally fitness equipment required for fitness. As the name implies, the counterweight blocks required for dumbbells are the weights required when using dumbbells. They are heavy objects used to increase one's own weight to maintain balance.

[0003] Currently, the dumbbells used on the market generally consist of a dumbbell rod and counterweight blocks. When using a dumbbell, first, the counterweight blocks are sleeved outside the dumbbell rod, and then the position of the counterweight blocks is fixed by nuts or positioning clips to facilitate subsequent use. However, when the current dumbbells are in use, the movement of the dumbbells will cause the counterweight blocks to continuously impact the nuts or positioning clips, which will cause the nuts and positioning clips to shift, possibly resulting in the detachment of the counterweight blocks and potentially causing harm to fitness personnel. Content of the Utility Model

[0004] In order to overcome the deficiencies of the prior art, the utility model provides an assembled dumbbell counterweight block, which has the advantage of reducing the possibility of harm to fitness personnel caused by the detachment of the counterweight block.

[0021] As Figures 1 to 5 shown, the present invention provides a assembled dumbbell counterweight, including a dumbbell rod 1. Two blocking blocks 2 are fixedly connected to both ends of the dumbbell rod 1. A screw 3 is fixedly connected to the outside of the blocking block 2. A positioning component is arranged on the outside of the screw 3, and a fixing component is arranged on the outside of the screw 3. The positioning component includes two fixed plates 4 fixedly connected to the end of the screw 3. A rotating rod 5 is rotatably connected between the two fixed plates 4. A torsion spring is fixedly connected between the rotating rod 5 and the fixed plate 4. A gear lever 6 is slidably connected inside the rotating rod 5. A spring is fixedly connected between the inside of the rotating rod 5 and the end of the gear lever 6. The fixed plate 4, the rotating rod 5 and the gear lever 6 are made of plastic material.

[0022] By rotating the rotating rod 5, the gear lever 6 is driven to rotate, so that the position of the fixing component is limited by the gear lever 6, thus facilitating the fixing of the position of the counterweight component.

[0023] Among them, the fixing component includes a nut 7 threadedly connected to the outside of the screw 3. A placement groove is opened inside the nut 7, and the placement groove is slidably connected to the outside of the gear lever 6.

[0024] By rotating the nut 7, the counterweight component is fixed, and then the position of the nut 7 is limited by the gear lever 6, thus reducing the possibility that the counterweight component shakes due to movement, resulting in the loosening of the nut 7, and thus improving the stability of the counterweight component.

[0025] Among them, a counterweight component is arranged on the outside of the screw 3. The counterweight component includes a counterweight 9 slidably connected to the outside of the screw 3. A base 8 is fixedly connected to the bottom of the counterweight 9, and a handle 12 is fixedly connected to the top of the counterweight 9.

[0026] By pulling up the handle 12, it is convenient to lift the counterweight 9, thus facilitating the assembly of the counterweight 9. By the contact of the base 8 with the ground, the stability of the counterweight 9 is improved, thus facilitating the assembly of the counterweight 9.

[0027] Among them, a limiting component is arranged on the outer side of the counterweight assembly. The limiting component includes a slider 11 fixedly connected to the outer side of the counterweight block 9. A chute 10 is formed inside the counterweight block 9, and the size of the chute 10 is adapted to that of the slider 11.

[0028] Through the cooperation between the slider 11 and the chute 10, the two counterweight blocks 9 can be in the same orientation, thereby reducing the possibility of the counterweight block 9 shaking.

[0029] Among them, a reset component is arranged inside the counterweight assembly. The reset component includes a steel ball 13 rotatably connected to the inside of the counterweight block 9. A rotating shaft 14 is slidably connected to the outer side of the steel ball 13. The inside of the rotating shaft 14 is slidably connected to the outer side of the screw 3, and the outer side of the rotating shaft 14 abuts against the outer side of the blocking block 2.

[0030] Through the cooperation of the rotating shaft 14 and the steel ball 13, the counterweight block 9 can automatically return to its original position even when it shakes, thereby facilitating the more convenient and stable placement of the dumbbell after the exercise.

[0031] Among them, the base 8, the handle 12 and the slider 11 are made of metal and are included in the total weight of the counterweight block 9.

[0032] By making the handle 12 and the slider 11 of metal, the firmness of the handle 12 and the slider 11 is improved. By making the base 8 of metal, it is convenient for the counterweight block 9 to return to its original position.
