[0023] A box body 13 is fixedly installed on the top of the support plate 19. A limiting hole 10 is opened inside the dumbbell rod 1. A limiting column 14 is movably installed inside the limiting hole 10. The limiting column 14 extends into the inside of the support plate 19. A pull rod 15 is fixedly installed on the limiting column 14, and one end of the pull rod 15 fixedly penetrates into the inside of the box body 13. A pull rod 15 is fixedly installed at one end of the pull rod 15. A button 16 is fixedly installed at one end of the pull rod 15. A spring 20 is fixedly installed between the limiting column 14 and the box body 13.
[0024] The staff first sleeved the second counterweight 8 on the outer surfaces of the dumbbell rod 1 and the limiting strip 9. Now, hold the button 16 by hand, pull the limiting column 14 inside the box body 13 through the button 16, squeeze the spring 20 through the limiting column 14, so that the limiting column 14 passes through the inside of the support plate 19 and enters the inside of the box body 13. At the same time, drive the support plate 19 to slowly move to the outer surfaces of the dumbbell rod 1 and the limiting strip 9 through the first counterweight 7, and slowly move the second counterweight 8 to the outside of the first counterweight 7 through the first counterweight 7. Now release the button 16. At this time, through the extrusion of the spring 20 on the limiting column 14, the limiting column 14 quickly enters the inside of the limiting hole 10 through the support plate 19, and the limiting column 14 is limited by the limiting hole 10, thereby completing the limitation of the first counterweight 7 and the second counterweight 8.
[0025] Pull the limit post 14 inside the box body 13 through the button 16, squeeze the spring 20 through the limit post 14, so that the limit post 14 passes through the inside of the support plate 19 and enters the inside of the box body 13. At the same time, drive the support plate 19 to slowly move to the outer surfaces of the dumbbell rod 1 and the limit strip 9 through the first counterweight 7, and slowly move the second counterweight 8 to the outside of the first counterweight 7. Now release the button 16. At this time, due to the extrusion of the spring 20 on the limit post 14, the limit post 14 quickly passes through the support plate 19 and enters the inside of the limit hole 10, and the limit post 14 is limited by the limit hole 10. Compared with traditional dumbbell counterweights, this dumbbell counterweight is convenient for limiting the first counterweight 7 and the second counterweight 8 through the cooperation between the limit hole 10 and the limit post 14, effectively preventing accidental detachment caused by loose hands and weakness, avoiding the risk of injury, especially protecting sensitive parts such as the feet. At the same time, this design enhances the stability of the dumbbell, reduces shaking, and improves the training comfort. In addition, it usually also takes into account the convenient adjustment of the counterweight, allowing users to easily increase or decrease the weight to meet diverse training needs, thus comprehensively optimizing the use experience.
[0026] Among them, a positioning groove 17 is opened inside the first counterweight 7, a limit block 18 is fixedly installed on the outer side of the second counterweight 8, and the outer diameter value of the limit block 18 is equal to the inner diameter value of the positioning groove 17, and the inside of the positioning groove 17 is designed with a smooth surface.
[0027] The staff needs to assemble the second counterweight 8 and the first counterweight 7 according to the needs of the fitness person. Hold the second counterweight 8 by hand, and put the second counterweight 8 on the outer surfaces of the dumbbell rod 1 and the limit strip 9. Now move the second counterweight 8 and the limit block 18 to the inner side of the stop block 12 on the outer surfaces of the dumbbell rod 1 and the limit strip 9. Then hold the first counterweight 7 by hand, put the first counterweight 7 on the dumbbell rod 1 and the limit strip 9 again, and then push the first counterweight 7 to move on the outer surfaces of the dumbbell rod 1 and the limit strip 9. Align the positioning groove 17 inside the first counterweight 7 with the outer surface of the limit block 18, and then push the positioning groove 17 onto the outer surface of the limit block 18, and limit the positioning groove 17 through the limit block 18, so as to complete the assembly of the first counterweight 7 and the second counterweight 8.
[0028] It is necessary to assemble the second counterweight 8 and the first counterweight 7 according to the needs of the fitness person. By holding the second counterweight 8 by hand, the second counterweight 8 is sleeved on the outer surfaces of the dumbbell rod 1 and the limiting strip 9. Now, on the outer surfaces of the dumbbell rod 1 and the limiting strip 9, the second counterweight 8 and the limiting block 18 are moved to the inside of the stop block 12. Then, by holding the first counterweight 7 by hand, the first counterweight 7 is sleeved on the dumbbell rod 1 and the limiting strip 9 again. Then, the first counterweight 7 is pushed to move on the outer surfaces of the dumbbell rod 1 and the limiting strip 9. The inner positioning groove 17 of the first counterweight 7 is aligned with the outer surface of the limiting block 18, and then the positioning groove 17 is pushed onto the outer surface of the limiting block 18. The limiting block 18 limits the positioning groove 17. Compared with the traditional dumbbell counterweight, this dumbbell counterweight is convenient for limiting the first counterweight 7 and the second counterweight 8 through the limiting block 18 and the positioning groove 17, avoiding the shaking of the first counterweight 7 and the second counterweight 8 during use, improving the stability of the first counterweight 7 and the second counterweight 8 during use, and improving the use efficiency of the positioning groove 17 and the limiting block 18.
[0029] Wherein, threaded grooves 11 are formed at both ends of the dumbbell rod 1, and bolts 5 are threadedly sleeved inside the threaded grooves 11. A rotating handle 6 is fixedly installed on the outer surface of the bolt 5.
[0030] By holding the rotating handle 6 by hand, the bolt 5 is driven by the rotating handle 6 to rotate on the outer surface of the threaded groove 11 until it reaches one end of the support plate 19. Through the cooperation between the threaded groove 11 and the bolt 5, it is convenient to fix the support plate 19. Then, the first counterweight 7 is fixed by the support plate 19, improving the stability of the first counterweight 7 and the second counterweight 8 during use.
[0031] Wherein, an anti-slip cloth 2 is fixedly installed on the outer surface of the dumbbell rod 1, and the anti-slip cloth 2 is made of rubber material.
[0032] Since the anti-slip cloth 2 is made of rubber material on the outer surface of the dumbbell rod 1, the anti-slip cloth 2 made of rubber material has good anti-slip performance, which can effectively increase the friction between the dumbbell rod 1 and the palm, preventing the dumbbell from slipping due to sweat or wetness during training, thus improving the safety of training.
[0033] Wherein, an anti-detachment ring 4 is fixedly installed at the bottom of the anti-slip cloth 2, and a connecting cloth 3 is fixedly installed at the bottom of the anti-detachment ring 4, and the number of the connecting cloths 3 is designed to be four.
[0034] Since the connecting cloth 3 is fixedly installed at the bottom of the anti - detachment ring 4, and the number of the connecting cloth 3 is designed to be four, the design of the connecting cloth 3 can effectively prevent the dumbbell plates from accidentally falling off during training, avoid the injuries or damage to items caused by the falling of the dumbbell plates, increase the safety of using dumbbells. Especially when performing high - intensity or rapid movements, it can reduce the risks caused by the instability of the dumbbells.
[0035] Among them, the rotating handles 6 are in a circumferential array form on the outer surface of the bolts 5, and the rotating handles 6 are made of stainless steel.
[0036] Since the rotating handles 6 are in a circumferential array form on the outer surface of the bolts 5 and the rotating handles 6 are made of stainless steel, it is convenient for the staff to hold the rotating handles 6 and drive the bolts 5 to rotate on the outer surface of the thread grooves 11, improving the rotation efficiency of driving the bolts 5 in the thread grooves 11 by the rotating handles 6.
[0037] The working principle and usage process of the present utility model:
[0038] The staff first sleeved the second counterweight 8 on the outer surfaces of the dumbbell rod 1 and the limiting strip 9. Now, by holding the button 16, the limiting column 14 is pulled inside the box body 13 through the button 16. The spring 20 is squeezed by the limiting column 14, so that the limiting column 14 passes through the inside of the support plate 19 and enters the inside of the box body 13. At the same time, the support plate 19 is driven by the first counterweight 7 to slowly move to the outer surfaces of the dumbbell rod 1 and the limiting strip 9. The first counterweight 7 slowly moves to the outside of the second counterweight 8. Now release the button 16. At this time, due to the spring 20 squeezing the limiting column 14, the limiting column 14 quickly passes through the support plate 19 and enters the inside of the limiting hole 10. The limiting column 14 is limited by the limiting hole 10, thus completing the limitation of the first counterweight 7 and the second counterweight 8.
[0039] The staff needs to assemble the second counterweight 8 and the first counterweight 7 according to the needs of the fitness person. By holding the second counterweight 8, the second counterweight 8 is sleeved on the outer surfaces of the dumbbell rod 1 and the limiting strip 9. Now, on the outer surfaces of the dumbbell rod 1 and the limiting strip 9, the second counterweight 8 and the limiting block 18 are moved to the inside of the stop block 12. By holding the first counterweight 7, the first counterweight 7 is sleeved on the dumbbell rod 1 and the limiting strip 9 again. Then, the first counterweight 7 is pushed to move on the outer surfaces of the dumbbell rod 1 and the limiting strip 9. The inner positioning groove 17 of the first counterweight 7 is aligned with the outer surface of the limiting block 18, and then the positioning groove 17 is pushed onto the outer surface of the limiting block 18. The limiting block 18 limits the positioning groove 17, thus completing the assembly of the first counterweight 7 and the second counterweight 8.
