Description

Technical Field

[0001] This utility model relates to the field of fitness equipment technology, and more specifically, to a dumbbell hydraulic buffer protection structure. Background Technology

[0002] Dumbbells are auxiliary equipment for weightlifting and fitness exercises. They are called dumbbells because they do not make any noise when used. Most dumbbells have weights at both ends, and users can adjust the overall weight of the dumbbell by adding or removing weights to perform weightlifting exercises.

[0003] A dumbbell with protective function, disclosed in Chinese Patent Publication No. CN220877634U, includes a dumbbell bar and dumbbell plates. Limiting grooves are formed on the outer sides of both sets of dumbbell plates, and buffer mechanisms are provided on the inner sides of both sets of limiting grooves. Each buffer mechanism includes an air bladder. Multiple sets of springs are installed on the inner sides of the limiting grooves, and the other ends of each set of springs are connected to the inner side of a connecting plate. The outer side of the connecting plate abuts against the top of the inner cavity of the limiting groove, and the air bladder is installed on the outer side of the connecting plate.

[0004] In the aforementioned device, airbags are installed on the outside of the dumbbell plates to reduce the impact force generated when the dumbbells fall during use. The number of dumbbell plates changes during training, so airbags need to be installed on the outside of each set of dumbbell plates, which increases the cost of use. In addition, the airbags can be punctured when they hit sharp objects, thus failing to achieve the cushioning effect. Utility Model Content

The other end of the several sets of springs 15 is connected to a hydraulic rod 10. The output end of the several sets of hydraulic rods 10 extends to the outside of the disc 2 and is slidably connected to the disc 2. An arc plate 4 is installed at the end of the output end of the several sets of hydraulic rods 10. An anti-slip component 7 is installed between the circular block 8 and the circular rod 1.

[0027] Furthermore, the anti-slip component 7 includes a limiting groove 73, several sets of the limiting grooves 73 are evenly opened on the outer wall of the circular block 8, and the limiting grooves 73 are connected to the outer wall of the circular rod 1. The inner walls of the several sets of limiting grooves 73 are all connected to limiting blocks 72. Anti-slip strips 71 are installed between several sets of opposing limiting blocks 72 located on the left and right sides of the circular rod 1. The anti-slip strips 71 are in tight contact with the outer wall of the circular rod 1. The limiting component 9 is in contact with the outer wall of the entry end of the limiting groove 73.

[0028] Furthermore, the limiting component 9 includes an annular ring 91, which is rotatably connected to the outer wall of the circular block 8.

Then, the nut 16 is attached to the outside of the threaded rod 17 and rotated until the nut 16 tightens the dumbbell plates 5 onto the threaded rod 17. Then, the bolt 11 on the disc 2 is rotated and tightened into the threaded groove 12. After that, training can begin. During training, if several sets of dumbbells are accidentally dropped, the arc plate 4 will contact the ground first. After the arc plate 4 is subjected to force, it will push the hydraulic rod 10 to compress the spring 15. The spring 15 will offset part of the impact force. When the spring 15 is compressed to its limit, the output end of the hydraulic rod 10 will drive the arc plate 4 to retract, thereby offsetting the remaining impact force. The anti-slip component 7 set on the outside of the round rod 1 can improve the user's grip on the round rod 1. The limiting component 9 can be unlocked by the locking component 13. The anti-slip component 7 can be installed or replaced by the limiting component 9.
