Dumbbells are one of the most commonly used training equipment in sports training.

[0003] A dumbbell for sports training, with Chinese patent publication number CN220110344U, includes a main shaft. The main shaft has two sliding grooves and two sliding grooves inside. A fixed shaft is slidably connected to the inner wall of each sliding groove. A connecting rod is fixedly connected to the end of each fixed shaft near the main shaft. A retaining ring is sleeved on the outer surface of each connecting rod. A plug is fixedly connected to the end of each connecting rod away from the fixed shaft. A stop is slidably connected to the inner wall of each sliding groove. A spring is fixedly connected to the upper surface of each stop, and the upper end of each spring is fixedly connected to the corresponding sliding groove.

[0004] However, the above-mentioned device still has a problem: since there is no protective device on the outside of the steel plate, when the dumbbell is accidentally dropped during training, the heavy steel plate will hit the ground directly, which will not only damage the ground, but the steel plate will also be damaged by the reaction force from the ground. More importantly, there is a risk of hitting the user's feet. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0026] Please see Figure 1-6 This utility model provides a technical solution:

[0027] An impact-resistant training dumbbell includes a dumbbell bar 1. Threaded rods 3 are fixedly installed at both ends of the dumbbell bar 1. Several sets of dumbbell plates 4 are sleeved on the outer walls of both sets of threaded rods 3. Rectangular grooves 5 are formed on the outer walls of the dumbbell plates 4, facilitating the removal of the dumbbell plates 4. Threaded sleeves 6 are threadedly connected to both sets of threaded rods 3, with the sidewalls of the threaded sleeves 6 in close contact with the outer walls of the dumbbell plates 4. Circular plates 9 are installed at both ends of the dumbbell bar 1 near the two sets of threaded rods 3. Several sets of limiting grooves 14 are evenly formed on the outer walls of the two sets of circular plates 9, with limiting grooves inserted into the inner walls of each of the limiting grooves 14. Block 13, limiting block 13 and limiting groove 14 are all T-shaped. Several sets of limiting blocks 13 are equipped with annular plates 12 on the outer wall near the middle of the circular plate 9. The outer wall of the annular plate 12 is equipped with annular ring 7. The annular ring 7 is elastic and the internal cavity of the annular ring 7 is sealed. The outer wall of the annular ring 7 is equipped with an air nozzle 8. The air nozzle 8 is used to inject gas into the annular ring 7. The outer wall of both sets of circular plates 9 is equipped with limiting components 10. The limiting components 10 are in contact with the outer wall of the limiting block 13. The limiting components 10 are connected to locking components 11. The outer wall of the middle of the dumbbell bar 1 is equipped with an anti-slip sleeve 2.

[0028] Furthermore, the limiting component 10 includes two annular rings 101, which are rotatably connected to the outer walls of two circular plates 9 respectively. Several sets of connecting rods 102 are evenly installed on the outer wall of the two annular rings 101 near the annular ring 7.

[0029] Furthermore, the outer walls of several sets of connecting rods 102 are each fitted with a limiting plate 103, and the inner walls of several sets of limiting plates 103 are in contact with the outer walls of several sets of limiting blocks 13 away from the circular plate 9. The second annular ring 101 is connected to the locking component 11. Unlocking the locking component 11 allows the second annular ring 101 to be rotated, causing it to drive the limiting plate 103 away from the entry end of the limiting groove 14 via the connecting rods 102, thereby facilitating the removal of the limiting block 13 with the second annular ring 101 installed from inside the limiting groove 14.

[0030] Furthermore, the locking assembly 11 includes a rectangular plate 111, two sets of rectangular plates 111 are fixedly connected to the outer walls of two sets of circular plates 9 respectively, and the side walls of the two sets of rectangular plates 111 are provided with circular holes 113, and the side wall of the annular ring 101 which is aligned with the circular holes 113 is provided with a groove 112.

[0031] Furthermore, a limiting rod 114 is inserted between the groove 112 and the round hole 113. A handle 115 is installed at the end of the limiting rod 114 near the outer end of the rectangular plate 111. A spring 116 is installed between the handle 115 and the rectangular plate 111. The spring 116 is sleeved on the outside of the limiting rod 114. Pulling the handle 115 outward causes the limiting rod 114 to leave the groove 112, thereby releasing the restriction on the annular ring 7 and facilitating the free rotation of the annular ring 7. When it is necessary to restrict the annular ring 7, the groove 112 on the annular ring 7 is rotated to align with the round hole 113, and the spring 116 will automatically push the limiting rod 114 into the groove 112.

[0032] Furthermore, the anti-slip sleeve 2 includes anti-slip blocks 21, a sweat-absorbing layer 22, a waterproof layer 23, and a sponge layer 24. The inner wall of the sponge layer 24 is in close contact with the outer wall of the dumbbell bar 1. The outer wall of the sponge layer 24 is provided with a waterproof layer 23. The outer wall of the waterproof layer 23 is provided with a sweat-absorbing layer 22. Several sets of anti-slip blocks 21 are evenly installed on the outer wall of the sweat-absorbing layer 22. The anti-slip blocks 21 are used to increase the friction between the anti-slip blocks and the palm. The sweat-absorbing layer 22 can absorb sweat, while the waterproof layer 23 can prevent sweat from entering the sponge layer 24, ensuring that the cushioning effect of the sponge layer 24 remains stable.

[0033] Working principle: The user places several sets of dumbbell plates 4 onto the threaded rod 3 in sequence according to the weight required for training. Then, the threaded sleeve 6 is put onto the threaded rod 3 and rotated to restrict the dumbbell plates 4 on the threaded rod 3. Next, the locking component 11 unlocks the limiting component 10, and the limiting component 10 unlocks the limiting groove 14. Then, the limiting block 13 with the ring plate 12 is inserted into the limiting groove 14. Then, the limiting component 10 limits the limiting block 13, and the locking component 11 locks the limiting component 10, ensuring that the ring ring 7 installed outside the ring plate 12 is stably installed on the outer wall of the dumbbell plates 4. Then, the air nozzle 8 fills the ring ring 7 with air, which enhances the elasticity of the ring ring 7. When the dumbbells are accidentally dropped during training, the ring ring 7 will contact the ground first, and the air inside will offset most of the impact force, ensuring that the ground and the dumbbell plates 4 will not be greatly damaged.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
