Description

Technical Field

[0001] This utility model relates to the field of dumbbell technology, and more specifically to a dumbbell that can reduce shock and noise. Background Technology

[0002] Dumbbells are a common type of strength training equipment, usually made of metal or rubber-coated material, with weight blocks at both ends and a handle in the middle. They come in two types: fixed weight and adjustable weight, suitable for home or gym use. Through different movements (such as curls, presses, squats, etc.), dumbbells can specifically train the upper limb, core, and lower limb muscle groups, improving muscle strength, endurance, and coordination. Their small size and flexible use make them suitable for the diverse needs of fitness enthusiasts from beginners to professionals, making them a practical tool for full-body training. Dumbbells, as a common fitness equipment, are versatile but also have some limitations, especially in noise-sensitive environments such as home gyms. When dumbbells are dropped, they produce significant vibration and noise. In addition, when using dumbbells, it is necessary to add or remove weight plates to change the weight, and the installation and removal of weight plates can cause noise due to collisions, which can affect nearby residents and cause great inconvenience. Utility Model Content

[0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides a dumbbell with shock absorption and noise reduction to solve the problems existing in the background art.

[0004] This utility model provides the following technical solution: a dumbbell with shock absorption and noise reduction, including a dumbbell bar, with mounting heads fixedly connected to both ends of the dumbbell bar, dumbbell plates movably sleeved on the surface of each mounting head, and a fixing nut fixedly connected to the surface of the mounting head by a thread, the dumbbell plates being fixedly sleeved on the surface of the mounting head by the fixing nut, the fixing nut facilitating the fixed installation of the dumbbell plates; Furthermore, anti-collision rings are fixedly connected to both sides of the dumbbell plate surface, and shock-absorbing components are regularly arranged around the perimeter of the dumbbell plate surface. By providing anti-collision rings, it is beneficial to isolate the dumbbell plates when multiple dumbbell plates are installed on the mounting head surface, thereby preventing the dumbbell plates from colliding with each other and generating noise.

[0005] Furthermore, the anti-collision ring and shock-absorbing components are made entirely of rubber. The rubber material helps to absorb and reduce some of the vibration force through the flexibility of the material itself, thereby reducing noise generation.

[0006] Furthermore, each dumbbell plate is fixedly fitted with a shock-absorbing pipe inside the shock-absorbing assembly. The shock-absorbing pipe helps to absorb and reduce the force generated by vibration.

[0007] Furthermore, telescopic rods are fixedly connected to both sides of the shock-absorbing component near the surface of the dumbbell plates. The telescopic rods are movably sleeved inside the shock-absorbing pipe. By providing the shock-absorbing component, shock-absorbing pipe, and spring, it is beneficial that when the dumbbell is placed for training, the shock-absorbing component impacts the ground, and the vibration generated by the impact is absorbed by the spring squeezed by the telescopic rod. At the same time, the vibration is further absorbed and reduced by the rubber material of the shock-absorbing component itself, thereby enabling the dumbbell to achieve the effect of shock absorption and noise reduction.

[0008] Furthermore, springs are movably sleeved inside the shock-absorbing pipes. These springs are located on the telescopic rod away from the bottom of the shock-absorbing component. By incorporating the shock-absorbing component, shock-absorbing pipes, and springs, when the dumbbells are used for training, the vibration generated by the impact between the shock-absorbing component and the ground is absorbed by the springs squeezed by the telescopic rod. At the same time, the vibration is further absorbed and reduced by the rubber material of the shock-absorbing component itself, thereby enabling the dumbbells to achieve the effect of shock absorption and noise reduction.

[0009] The technical effects and advantages of this utility model are as follows: 1. This utility model, by incorporating an anti-collision ring, helps to prevent noise caused by the dumbbell plates colliding with each other when multiple dumbbell plates are installed on the surface of the mounting head.

[0010] 2. This utility model, by incorporating a shock-absorbing component, shock-absorbing pipeline, and spring, facilitates the absorption of vibrations generated when the dumbbells are placed for training and use. The vibrations are absorbed by the spring through the compression of the telescopic rod, and further reduced by the rubber material of the shock-absorbing component itself, thereby achieving the effect of shock absorption and noise reduction for the dumbbells.

[0011] 3. By incorporating shock-absorbing components and a telescopic rod, this utility model facilitates the movement of the shock-absorbing components towards the dumbbell plate when it lands, thereby creating gaps between the shock-absorbing components and preventing the dumbbell plate from rolling after landing, thus avoiding noise caused by rolling.

[0018] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The shock-absorbing and noise-reducing dumbbell involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0019] Reference Figures 1-5 As shown, this utility model provides a dumbbell with shock absorption and noise reduction, including a dumbbell bar 1, with mounting heads 3 fixedly connected to both ends of the dumbbell bar 1, dumbbell plates 2 movably sleeved on the surface of the mounting heads 3, and fixing nuts 4 fixedly connected to the surface of the mounting heads 3 by threads, and the dumbbell plates 2 are fixedly sleeved on the surface of the mounting heads 3 by the fixing nuts 4. The fixing nuts 4 facilitate the fixed installation of the dumbbell plates 2. The dumbbell plate 2 has anti-collision rings 201 fixedly connected to both sides of its surface, and shock-absorbing components 202 arranged in a regular pattern are provided around the surface of the dumbbell plate 2. The anti-collision rings 201 help to block the dumbbell plates when multiple dumbbell plates 2 are installed on the surface of the mounting head 3, thus preventing the dumbbell plates 2 from colliding with each other and generating noise.

[0020] Among them, the anti-collision ring 201 and the shock absorption component 202 are made of rubber. The fact that the anti-collision ring 201 and the shock absorption component 202 are made of rubber helps to absorb and reduce some of the vibration force through the flexibility of the material itself, thereby reducing the generation of noise.

[0021] Among them, the dumbbell plates 2 are all fixedly sleeved with shock-absorbing pipes 203 inside the shock-absorbing component 202. Through the shock-absorbing pipes 203, the force generated by vibration is absorbed and reduced.

[0022] The shock-absorbing component 202 has telescopic rods 204 fixedly connected to both sides of the dumbbell plate 2. The telescopic rods 204 are movably sleeved inside the shock-absorbing pipe 203. With the shock-absorbing component 202, the shock-absorbing pipe 203, and the spring 5, when the dumbbell is placed for training, the shock-absorbing component 202 impacts the ground, and the vibration generated by the impact is absorbed by the spring 5 squeezed by the telescopic rod 204. At the same time, the vibration is further absorbed and reduced by the rubber material of the shock-absorbing component 202 itself, so that the dumbbell achieves the effect of shock absorption and noise reduction.

[0023] The shock-absorbing pipe 203 is equipped with springs 5 ​​that are movably connected inside. The springs 5 ​​are located on the telescopic rod 204 away from the bottom of the shock-absorbing component 202. By providing the shock-absorbing component 202, the shock-absorbing pipe 203, and the springs 5, when the dumbbell is placed for training, the shock-absorbing component 202 impacts the ground, and the vibration generated by the impact is absorbed by the springs 5 ​​squeezed by the telescopic rod 204. At the same time, the vibration is further absorbed and reduced by the rubber material of the shock-absorbing component 202 itself, so that the dumbbell achieves the effect of shock absorption and noise reduction.

[0024] The working principle of this utility model: First, when using the dumbbells, pick up the dumbbell plate (2) to be installed and fit it onto the surface of the mounting head (3). Then, rotate the fixing nut (4) to fix the dumbbell plate (2) in place on the mounting head (3). Then, hold the dumbbell bar (1) and lift the dumbbells for training. When the dumbbells are lifted and lowered to the ground, they fall due to gravity. At this time, the shock absorption component (202) contacts the ground and drives the telescopic rod (204) to compress the spring (5) inside the shock absorption pipe (203). The vibration force is then compressed by the spring (5) and the shock absorption pipe (203). The flexibility of the shock absorber (202) itself absorbs and reduces the force of the vibration. Then, the shock absorber (202) in contact with the ground is pressed down by the weight of the dumbbell plate (2) and the dumbbell bar (1). At this time, the shock absorber (202) drives the telescopic bar (204) to move closer to the dumbbell plate (2). Then, the shock absorber (202) that is not in contact with the ground is kept in normal state by the push of the spring (5). At this time, the shock absorber (202) around the surface of the dumbbell plate (2) appears irregularly shaped. At this time, the dumbbell plate (2) cannot roll on the ground, thus avoiding the generation of noise caused by the rolling of the dumbbell plate (2).
