Technical Field
[0001] The utility model relates to the technical field of fitness equipment, in particular to an outer ring shock-absorbing dumbbell. Background Art
[0002] Fitness exercise refers to sports activities that are performed by hand or with various equipment, using special scientific movements and methods, with the purpose of developing muscles, increasing physical strength, improving body shape and cultivating sentiments.
[0003] Dumbbells are a kind of sports equipment with simple structure. They are very common in gyms and homes. Dumbbells are simple equipment used to enhance muscle strength training. They are favored by fitness enthusiasts because of their small size and light weight.
[0004] Dumbbells are an auxiliary equipment for weightlifting and fitness exercises. They are smaller than barbells. Light dumbbells have weights of 1, 2, 3, 5, 8, and 12 pounds (1 pound = 0.4536 kilograms), and heavy dumbbells have weights of 10, 15, and 30 kilograms. Because they are silent during exercise, they are named dumbbells. Dumbbells are a simple equipment used to enhance muscle strength training. Its main material is cast iron, and some are covered with a layer of rubber. Its purpose is to train muscle strength and muscle compound movements. Patients with low muscle strength due to motor paralysis, pain, long-term inactivity, etc. can hold dumbbells and use the weight of dumbbells to perform active resistance exercises to train muscle strength. When using, the weight of the dumbbells can be adjusted by adjusting the number of dumbbell pieces and the weight of the dumbbell pieces, which is convenient for different groups of people to use.
[0005] The existing dumbbell plates are mostly made of cast iron. During exercise, when the hands sweat, they are very likely to fall off the hands and fall to the ground. Because the dumbbell plates have no corresponding buffering and shock-absorbing structure, when the dumbbells fall, the dumbbell plates come into contact with the ground, and the impact easily causes damage to the ground.
[0006] To this end, we propose an outer ring shock-absorbing dumbbell to solve the above-mentioned problems. Utility Model Content

DETAILED DESCRIPTION
[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0024] Reference Figure 1-5 , an outer ring shock-absorbing dumbbell, comprising a dumbbell plate body 1, a shock-absorbing frame 2 and a dumbbell rod 3. The inner wall of the shock-absorbing frame 2 is provided with an annular groove 20, and the dumbbell plate body 1 is slidably arranged on the inner side of the annular groove 20. The center position of the dumbbell plate body 1 is penetrated by a circular connecting port 15, and the circular connecting port 15 is used to connect the dumbbell rod 3. The inner side of the circular connecting port 15 is plugged with a dumbbell rod 3, and the annular protrusion on the dumbbell rod 3 abuts against the dumbbell plate body 1. The dumbbell rod 3 is threadedly connected with a positioning nut 31, and the dumbbell plate body 1 is abutted inwardly along the dumbbell rod 3 through the positioning nut 31. The dumbbell plate body 1 is placed on the dumbbell rod 3, and the positioning nut 31 is connected to the side of the dumbbell plate body 1. The dumbbell rod 3 is provided with a friction groove 32. The setting of the friction groove 32 can increase the friction between the dumbbell rod 3 and the hand to play an anti-slip effect.
[0025] In detail, the outer circumferential surface of the dumbbell plate body 1 is symmetrically provided with first arcuate annular wall grooves 11, the number of the first arcuate annular wall grooves 11 is 2, and the first arcuate annular wall grooves 11 are used to install the elastic ball 12 and the orbital rotation of the elastic ball 12.
[0026] Furthermore, one end of the spring 14 is evenly and symmetrically welded to the inner wall of the annular groove 20, and a connecting ring 13 is welded to the other end of the spring 14. The connecting ring 13 is located on the inner side of the annular groove 20. When the shock-absorbing frame 2 falls and contacts the ground, the dumbbell body 1 moves downward along the annular groove 20 and abuts the connecting ring 13 through the elastic ball 12 to abut against the inner wall of the annular groove 20. When the connecting ring 13 moves downward, it squeezes the spring 14 at the lower end and pulls the spring 14 in other directions, so that the elastic force and pulling force of the spring 14 can be used for buffering.
[0027] Furthermore, the inner wall of the connecting ring 13 is symmetrically provided with third arcuate annular wall grooves 131, the number of the third arcuate annular wall grooves 131 is 2, the third arcuate annular wall grooves 131 correspond to the positions of the first arcuate annular wall grooves 11, and the first arcuate annular wall grooves 11 and the third arcuate annular wall grooves 131 are used to install the elastic ball 12.
[0028] In more detail, an elastic ball 12 is rollingly connected between the first arcuate annular wall groove 11 and the third arcuate annular wall groove 131. The elastic ball 12 can rotate along the first arcuate annular wall groove 11 and the third arcuate annular wall groove 131, so that when the dumbbell body 1 rotates, the connecting ring 13 will not drive the pulling spring 14 to rotate. When the dumbbell body 1 moves downward along the annular groove 20, the connecting ring 13 abuts against the inner wall of the annular groove 20 to squeeze the elastic ball 12, and the elastic ball 12 can provide elastic buffering.
[0029] In general, the outer circumferential surface of the shock absorbing frame 2 is symmetrically provided with second arcuate annular wall grooves 21, the number of the second arcuate annular wall grooves 21 is 3, and the inner side of the second arcuate annular wall groove 21 is connected with an annular shock absorbing ring 22, the annular shock absorbing ring 22 is made of rubber material, and when the shock absorbing frame 2 falls, it contacts the ground, and can provide buffering protection through the three annular shock absorbing rings 22.
[0030] Finally, the inner diameter of the shock absorbing frame 2 is not greater than the diameter of the dumbbell plate body 1 , which can prevent the dumbbell plate body 1 from falling from the inner side of the annular groove 20 .
[0031] Working method: When the dumbbell is in use, if it falls, when the shock absorbing frame 2 contacts the ground, the annular shock absorbing ring 22 will first contact the ground, and the three annular shock absorbing rings 22 can provide buffering at the first time when they touch the ground. Then the dumbbell body 1 moves downward along the annular groove 20 and abuts the connecting ring 13 through the elastic ball 12, so that the connecting ring 13 abuts downward against the inner wall of the annular groove 20. When the connecting ring 13 moves downward, the spring 14 at the lower end of the connecting ring 13 is squeezed. At the same time, other springs 14 connected to the connecting ring 13 will pull the connecting ring 13, so that buffering can be provided through the elastic force and pulling force of the spring 14. Finally, after the connecting ring 13 abuts against the inner wall of the annular groove 20, the dumbbell body 1 will squeeze the elastic ball 12, and the elastic ball 12 can provide elastic buffering again, so that the ground can be effectively prevented from being damaged through three layers of buffering and shock absorption.
[0032] The dumbbell bar 3 is provided with friction grooves 32 , and the friction grooves 32 can increase the friction between the dumbbell bar 3 and the hand to achieve an anti-slip effect.
[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
