Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-6 This utility model provides a technical solution:

[0029] A dumbbell with electromagnetic connection includes a dumbbell bar 1. Electromagnetic connection components 6 are installed at both ends of the dumbbell bar 1. Threaded rods 11 are connected to the other ends of both sets of electromagnetic connection components 6. Several sets of dumbbell plates 4 are sleeved onto both sets of threaded rods 11. Annular iron plates 17 are installed on the outer walls of both sides of each set of dumbbell plates 4. The annular iron plates 17 on the outer walls of the dumbbell plates 4 are connected to the electromagnetic connection components 6. The several sets of dumbbell plates 4 are tightly connected together by the magnetic attraction of the electromagnetic connection components 6 and the annular iron plates 17. Nuts 10 are threaded onto the outer walls of the two sets of threaded rods 11. The nuts 10 are connected to the electromagnetic connection components 6 and are positioned away from the electromagnetic connection components. The dumbbell plate 4 of the magnetic connection assembly 6 contacts the outer wall. The outer ends of the two sets of threaded rods 11 are provided with threaded grooves 13. The inner walls of the two sets of threaded grooves 13 are threaded with threaded rods 12. The outer ends of the two sets of threaded rods 12 are each equipped with a disc 2. The outer walls of the two sets of discs 2 away from the threaded rods 12 are evenly provided with several sets of limiting grooves 16. The limiting grooves 16 are T-shaped and penetrate the outer wall of the disc 2. The inner walls of the several sets of limiting grooves 16 are all connected with limiting blocks 15. The outer walls of the several sets of limiting blocks 15 are connected with an annular airbag 5. The outer wall of the disc 2 away from the threaded rods 12 and the limiting blocks 15 are connected with a limiting assembly 9.

[0030] Furthermore, the electromagnetic connection assembly 6 includes an annular disk 61, with an annular compartment inside the annular disk 61. Two sets of annular disks 61 are fixedly connected to the left and right ends of the dumbbell bar 1, respectively. The other side of the two sets of annular disks 61 is connected to the threaded rod 11. Coils 62 are installed on the inner walls of the two sets of annular disks 61, and electronic control devices 63 are installed on the outer walls of the two sets of annular disks 61. Battery compartments 64 are provided on the side walls of the electronic control devices 63. The electronic control devices 63 are electrically connected to the coils 62. A battery is installed inside the battery compartments 64 to provide power to the electronic control devices 63. When the electronic control devices 63 are energized, they generate electromagnetic force, thereby attracting the annular iron piece 17.

[0031] Furthermore, the limiting component 9 includes an annular ring 91, which is rotatably connected to the side wall of the disc 2 away from the threaded rod 12. Several sets of limiting plates 92 are evenly installed on the outer wall of the annular ring 91. The several sets of limiting plates 92 are in contact with the outer wall of the entry end of the limiting groove 16. After rotating the annular ring 91 so that the limiting plates 92 leave the outside of the entry end of the limiting groove 16, the limiting block 15 with the annular airbag 5 installed can be removed from the inside of the limiting groove 16.

[0032] Furthermore, several sets of limiting plates 92 are equipped with protrusions 2 93 on their outer walls, and the outer wall of the disc 2 near the annular ring 91 is equipped with protrusion 1 3. The protrusion 1 3 facilitates the rotation of the disc 2, so that the threaded rod 2 12 connected to its outer wall can be connected to or disconnected from the threaded groove 13.

[0033] Furthermore, a handle 7 is installed on the outer wall of the dumbbell bar 1. The handle 7 includes an arc-shaped plate 71. The inner walls of the two sets of arc-shaped plates 71 are in close contact with the outer wall of the dumbbell bar 1. Annular plates 72 are installed on the outer walls of the left and right sides of the two sets of arc-shaped plates 71. Rectangular plates 73 are installed on the outer walls of the front and rear sides of each set of annular plates 72. The rectangular plates 73 on the outer walls of the two sets of annular plates 72 on the same side of the dumbbell bar 1 are fixedly connected by bolts. When the arc-shaped plates 71 need to be replaced, the bolts can be loosened to separate the rectangular plates 73, thereby removing the two sets of arc-shaped plates 71 from the outer wall of the dumbbell bar 1.

[0034] Furthermore, the outer wall of the curved plate 71 is provided with a groove 8. The curved plate 71 is made of rubber. The groove 8 conforms to the shape of the fingers, making it convenient for the user to grip the curved plate 71. The rubber curved plate 71 will not hurt the fingers when used.

[0035] Furthermore, the outer wall of the annular airbag 5 is provided with an air nozzle 14, through which the annular airbag 5 can be inflated and deflated.

[0036] Working principle: Open the electromagnetic connection component 6, then place several sets of dumbbell plates 4 onto the threaded rod 11 according to the training gravity. The electromagnetic force generated by the electromagnetic connection component 6 will tightly attract the dumbbell plates 4 with the annular iron plate 17 installed. When it is necessary to remove the dumbbell plates 4, close the electromagnetic connection component 6. The electromagnetic attraction will disappear, and the dumbbell plates 4 can be removed. When the power of the electromagnetic connection component 6 is used up, the dumbbell plates 4 can also be tightly fixed on the threaded rod 11 by turning the nut 10 to connect with the threaded rod 11. After the dumbbell plates 4 are adjusted, insert the threaded rod 2 12 on the disc 2. Inside the threaded groove 13, rotate the disc 2 to tightly connect the threaded rod 12 with the inside of the threaded groove 13, and you can start training. During training, if the dumbbell accidentally falls from your hand, the annular airbag 5 outside the disc 2 will be the first to contact the ground. The gas inside the annular airbag 5 will greatly buffer the impact force generated by the ground contact, preventing damage to the person, the ground, or the dumbbell plate 4. When the annular airbag 5 needs to be replaced, remove the limiting component 9 from the entry end of the limiting groove 16, and the limiting block 15 with the annular airbag 5 installed can be taken out from the limiting groove 16 for replacement.
