Description

Technical Field

[0001] The utility model relates to the technical field of sports equipment, in particular to a non-slip dumbbell. Background Art

[0002] Dumbbell is an auxiliary equipment for weightlifting and fitness exercises. It is smaller than a barbell. Its main material is cast iron. Some are covered with a layer of rubber. It is named because there is no sound during exercise. The shape of the dumbbell is usually an iron rod at one end and a solid ball at the other end. The standard dumbbell has a fixed weight, but there are also some dumbbells with adjustable weight. The weight is adjusted by increasing or decreasing the number of dumbbell plates.

[0003] Traditional dumbbells have some problems during use, such as the handle part is easy to slide, making it difficult for users to maintain a stable grip during exercise, and the fixing nuts of the dumbbell plates are loose, causing the dumbbell plates to tilt, which not only affects the exercise effect but also may increase the risk of injury. Therefore, there is an urgent need for an anti-slip dumbbell to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide an anti-slip dumbbell to solve the problems raised in the above background technology.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] The utility model realizes the fastening of the dumbbell pieces through the synergistic effect of the fixing nut, the damping rubber ring and the anti-skid rubber sleeve, and effectively avoids the risk of the dumbbell pieces loosening and falling off during use. When the fixing nut is tightened, the damping rubber ring is squeezed and deformed by the thread of the threaded support rod, and clings to the inner wall of the thread, thereby increasing the damping of the fixing nut and further enhancing the anti-loosening effect. The anti-skid convex points on the anti-skid rubber sleeve are squeezed and deformed when contacting the dumbbell pieces, thereby enhancing the damping effect between the inner clamping ring and the dumbbell pieces. At the same time, the elasticity of the anti-skid rubber sleeve can also slow down the shaking amplitude of the dumbbell pieces. The convex design on the outer side of the anti-skid handle also strengthens the anti-skid effect between the palm and the anti-skid handle, thereby achieving an overall anti-skid effect and improving safety in use.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-4 The utility model provides an embodiment: a non-slip dumbbell, comprising a nut fixing body 1 and a dumbbell body 2, the nut fixing body 1 is symmetrically arranged on the dumbbell body 2, the nut fixing body 1 comprises a fixing nut 3, a plum wrench 4, an inner snap ring 5, a non-slip rubber sleeve 6, an embedded groove 7 and a damping rubber ring 8, the plum wrench 4 is fixedly connected to one end of the fixing nut 3, the inner snap ring 5 is fixedly connected to the other end of the fixing nut 3, the non-slip rubber sleeve 6 is nested on the outside of the inner snap ring 5, the embedded groove 7 is opened on the inner side wall of the plum wrench 4, and the damping rubber ring 8 is nested inside the embedded groove 7.

[0020] The dumbbell body 2 includes an anti-slip handle 9, a limiting ring 10, an anti-slip pad 11, a threaded support rod 12 and a dumbbell plate 13. The limiting ring 10 is symmetrically fixedly connected to the two ends of the anti-slip handle 9, the threaded support rod 12 is symmetrically arranged, and one end of the threaded support rod 12 is fixedly connected to the end of the limiting ring 10 away from the anti-slip handle 9, the anti-slip pad 11 is evenly arranged, and the anti-slip pad 11 is nested on the outside of the threaded support rod 12, the dumbbell plates 13 are symmetrically arranged, and the threaded support rod 12 is slidably inserted in the middle of the dumbbell plates 13, and the anti-slip pad 11 is located between the two dumbbell plates 13.

[0021] The fixing nut 3 is threadedly connected to the threaded support rod 12 , and the dumbbell plate 13 is fastened by the fixing nut 3 to prevent the dumbbell plate 13 from loosening and falling off.

[0022] The plum blossom wrench 4 is designed in a plum blossom shape, which is convenient for the user to manually tighten and install the fixing nut 3.

[0023] The anti-skid rubber sleeve 6, the damping rubber ring 8 and the anti-skid spacer 11 are all made of rubber, and the anti-skid rubber sleeve 6 is evenly provided with anti-skid protrusions on the side away from the fixing nut 3. The anti-skid protrusions are in contact with the side end of the dumbbell plate 13 and squeezed and deformed to enhance the damping effect between the inner clamping ring 5 and the dumbbell plate 13. The anti-skid rubber sleeve 6 is elastic. When the dumbbell plate 13 shakes, the elasticity of the anti-skid rubber sleeve 6 slows down the shaking amplitude of the dumbbell plate 13, thereby reducing the risk of loosening of the fixing nut 3. The inner end of the damping rubber ring 8 is flush with the bottom end of the thread groove of the threaded support rod 12. When tightening the fixing nut 3, the damping rubber ring 8 is squeezed and deformed by the thread of the threaded support rod 12. At this time, the inner side of the damping rubber ring 8 is squeezed and deformed by the thread of the threaded support rod 12 and is close to the inner wall of the thread. The damping of the fixing nut 3 is increased by the friction between the damping rubber ring 8 and the threaded support rod 12, thereby achieving the anti-loosening effect of the fixing nut 3.

[0024] The outer side of the anti-slip handle 9 is evenly provided with protrusions, and the anti-slip effect between the palm and the anti-slip handle 9 is enhanced by the protrusions on the outer side of the anti-slip handle 9.

[0025] Working principle: During use, a dumbbell piece 13 of appropriate weight is selected according to the needs of the user, and then two anti-skid spacers 11 are respectively nested on two threaded support rods 12 by external force, and then the selected dumbbell piece 13 is divided into two equal parts, and one of the dumbbell pieces 13 is nested on the threaded support rod 12 in sequence by external force, and an anti-skid spacer 11 is nested between the two dumbbell pieces 13. After the outermost dumbbell piece 13 is nested, the fixing nut 3 is threadedly connected to the threaded support rod 12 by external force, and the plum wrench 4 is twisted close to the dumbbell piece 13 by external force until the end of the anti-skid rubber sleeve 6 away from the plum wrench 4 is close to the side end of the dumbbell piece 13. At this time, the dumbbell piece 13 and the anti-skid spacer 11 are tightly attached in sequence The damping effect between the dumbbell pieces 13 is strengthened to avoid shaking during use. The anti-skid protrusions on the anti-skid rubber sleeve 6 are squeezed and deformed to fit tightly against the side ends of the dumbbell pieces 13. The anti-skid effect is achieved through the friction between the anti-skid protrusions and the side ends of the dumbbell pieces 13. At this time, the inner side of the damping rubber ring 8 is squeezed and deformed by the threads of the threaded support rod 12 to fit tightly against the inner wall of the threads. The damping of the fixing nut 3 is increased through the friction between the damping rubber ring 8 and the threaded support rod 12, thereby achieving the anti-loosening effect of the fixing nut 3. Then, another dumbbell piece 13 is installed and fixed on the other anti-skid spacer 11 in the same way. The anti-skid effect between the palm and the anti-skid handle 9 is strengthened through the protrusions on the outside of the anti-skid handle 9, thereby achieving an overall anti-skid effect.
