Detailed Embodiments
[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0027] Embodiment 1:
[0028] Please refer to Figure 1-2 , this embodiment provides a multifunctional dumbbell, including a counterweight bin 1 and a connecting mechanism 2 movably connected to the counterweight bin 1;
[0029] The counterweight bin 1 is a hollow structure inside, and a partition plate 11 is fixedly arranged therein. The partition plate 11 divides the counterweight bin 1 into a first cavity 12 and a second cavity 13. A connection port 14 is arranged on one side of the counterweight bin 1. A rotating groove 15 is arranged inside the connection port 14, and a limiting block 16 is fixedly arranged in the rotating groove 15. A positioning opening 17 is arranged on the connection port 14 in a direction perpendicular to the partition plate 11;
[0030] The connecting mechanism 2 includes a rotating shaft 21. The rotating shaft 21 is a semi-hollow tubular structure. Positioning rods 22 are fixedly arranged at both ends of the rotating shaft 21. The direction of the positioning rods 22 is perpendicular to the diameter plane formed by the semi-hollow rotating shaft 21. A water injection port 24 is arranged at one end of the rotating shaft 21. The position of the water injection port 24 is outside the inner hollow part of the rotating shaft 21. A water injection cap 25 is detachably arranged on the water injection port 24;
[0031] When the connecting mechanism 2 is connected to the connection port 14, the positioning rod 22 cooperates with the positioning opening 17. After the positioning rod 22 is inserted into the rotating groove 15 and rotated clockwise or counterclockwise, it stops rotating when it touches the limiting block 16, so that the hollow part of the rotating shaft 21 can communicate with the first cavity 12 or the second cavity 13 to form a communicating vessel. After injecting liquid through the water injection port 24, the liquid in the two counterweight bins 1 can be made equal, so as to achieve the effects of equal weight and adjustable weight.
[0032] In this embodiment, the first cavity 12 and the second cavity 13 can accommodate water or beverages. The water and beverages can be injected or poured out through the water injection port 24, and the weight of the liquid in the counterweight bin 1 can be adjusted according to one's own needs.
[0033] In this embodiment, bearings 23 are arranged at both ends of the rotating shaft 21. The outer diameter of the rotating shaft 21 matches the inner diameter of the connection port 14. The area between the two bearings 23 is the hand-held area.
[0034] In this embodiment, an indicating member 26 is fixedly arranged on the rotating shaft 21. The position of the indicating member 26 is at the top of the hollow part of the rotating shaft 21. Since the inside of the rotating shaft 21 is a semi-hollow structure, the position of the hollow part cannot be seen from the outside. The indicating member 26 fixedly connected can play an indicating role.
[0035] In this embodiment, the grip rod 27 is connected to the rotating shaft 21 with a clearance, and the grip rod 27 can slide on the rotating shaft 21.
[0036] In this embodiment, the grip rod 27 is a hollow tubular structure, and its diameter is larger than the outer diameter of the rotating shaft 21. The grip rod 27 can wobble on the rotating shaft 21. When the first cavity 12 or the second cavity 13 is filled, during movement, the grip rod 27 can be wobbled. The rotation of the counterweight bin 1 drives the rotation of the rotating shaft 21, achieving the effect of movement and having fun.
[0037] In this embodiment, the counterweight bin 1 is a hexahedron. During the water injection process, placing one side of the hexahedron on the table can achieve a stable water injection effect.
[0038] Embodiment 2:
[0039] The difference between this embodiment and Embodiment 1 is that two drinking ports 18 are arranged on the side of the counterweight bin 1 away from the connection port 14. The positions of the drinking ports 18 are respectively matched with the first cavity 12 and the second cavity 13. A drinking cover 19 is movably connected to the drinking port 18. During the movement process, the dumbbell can become a drinking kettle.
[0040] In this embodiment, a sealing gasket is arranged on the inner side of the drinking cover 19. During the movement process, the liquid in the counterweight bin 1 will exert an outward force on the drinking cover 19, which is likely to make the drinking cover 19 loose. The sealing gasket plays a role in strengthening the fastening.
[0041] When in use, the fitness personnel can carry an empty dumbbell, which is relatively light. When weighting is needed, the positioning rod 22 is inserted into the positioning opening 17 and reaches the rotating groove 15, and then rotated clockwise. The positioning rod 22 stops after reaching the limiting block 16. The rotating groove 15 is matched with the positioning rod 22 and fastened, so that the positioning rod 22 is fixed beside the limiting block 16. At this time, the hollow part of the rotating shaft 21 is communicated with the second cavity 13. The counterweight bin 1 is rolled so that both the second cavity 13 and the hollow part of the rotating shaft 21 are vertically upward. The water injection port 24 is opened, and liquid is injected. It can be filled, or a certain amount of liquid can be injected according to one's own needs. The liquid flows from the hollow part of the rotating shaft 21 to one of the cavities in the counterweight bins 1 at both ends. According to the principle of the communicating vessel, after injecting the liquid and waiting for a few seconds, the liquid in the dumbbell is at the same horizontal plane. At this time, the liquid weights in the counterweight bins 1 at both ends are equal, and then the water injection cover 25 is covered.
[0042] The fitness enthusiast holds the grip rod 27 with both hands and makes circles in a plane perpendicular to the body. Since the center of gravity of the counterweight bin 1 is not fixed, the counterweight bin 1 drives the rotation shaft 21 to rotate. The fitness enthusiast's hand continues to control the position and rotation frequency of the entire dumbbell, achieving the fitness effect and being interesting.
[0043] In Embodiment 2, the dumbbell can be used as a vessel for drinking water or beverages. Open the drinking lid 19 on the liquid injection side and drink through the drinking port 18. After drinking, cover the drinking lid 19 and continue exercising.
[0044] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
