Description

Technical Field

[0001] This utility model relates to the field of dumbbell technology, specifically to a dumbbell with an aging-resistant structure. Background Technology

[0002] With increasing health awareness, fitness has become an important part of daily life, and dumbbells, as a common and practical piece of fitness equipment, are favored by many fitness enthusiasts. During frequent use, the structural stability and durability of the dumbbells' components are crucial for ensuring the effectiveness of the workout and the safety of the user. However, traditional dumbbells have gradually revealed some problems that urgently need to be addressed in practical applications.

[0003] From a durability perspective, the weight plates of traditional dumbbells are mostly exposed to the external environment and lack protective structures. During daily fitness training, dumbbells are often subject to various accidents, such as being accidentally dropped to the ground or colliding with surrounding equipment and objects during placement and retrieval. Over time, this not only easily leads to physical damage such as deformation and cracks in the weight plates, thus affecting the accuracy of dumbbell weight distribution, but also makes the weight plates more susceptible to corrosion from external factors such as air, moisture, and dust, accelerating their aging, causing a decline in their material performance, and ultimately shortening the overall lifespan of the dumbbell. This forces users to frequently replace dumbbells, increasing fitness costs and causing inconvenience to a continuous fitness plan. Utility Model Content

[0005] Preferably, the inner wall of the counterweight plate is fitted onto the outer wall of the sleeve, the outer wall of the rubber plate is fixedly connected to the outer wall of the rubber ring, the wall of the rubber ring is provided with a damping groove, and the damping groove is arranged in a ring along the central axis of the rubber ring. The damping groove is a closed cavity. The inner wall of the sleeve is slidably connected to the outer walls on both sides of the rod, and the outer walls on both sides of the rod are tactilely connected to the outer walls of the damping balls.

[0006] Preferably, the limiting component includes a fixing plate, a locking block is fixedly connected to the outer wall of the fixing plate, the locking block is made of an elastic material, a pull column is slidably connected to the outer wall of the fixing plate through a fixing shell, and the inner wall of the fixing shell is slidably connected to the outer wall of the pull column, a connecting frame is slidably connected to the inner wall of the fixing plate, and a tension spring is fixedly connected to the outer wall of the connecting frame.

[0007] Preferably, the end of the tension spring away from the connecting frame is fixedly connected to the outer wall of the fixing plate, the side of the connecting frame near the fixing plate is fixedly connected to a push plate, the connecting frame includes a connecting ring and a sliding rod, and the sliding rod is arranged in a ring along the central axis of the connecting ring, the outer wall of the fixing shell is fixedly connected to a tension spring, and the outer wall of the fixing shell is fixedly connected to the outer wall of the fixing plate.

[0008] Preferably, the end of the tension spring away from the fixed shell is fixedly connected to the outer wall of the pull column, the tension spring is arranged in a ring along the central axis of the fixed shell, and the outer wall of the pull column is slidably connected to the inner wall of the locking block.

[0010] The beneficial effects of this utility model are as follows:

[0011] 1. This utility model incorporates a protective component. The shock-absorbing groove on the rubber ring within the protective component plays a crucial role. When the dumbbell is accidentally dropped to the ground or collides with other objects, the impact force is transmitted to the rubber ring. The shock-absorbing groove absorbs and disperses this impact force through its own deformation, preventing the impact force from directly acting on the internal weight plate. This provides excellent protection for the weight plate. Even in the event of an accidental impact during daily exercise, the weight plate is protected from damage. Furthermore, the rubber ring, rubber plate, and sleeve enclose the weight plate, thereby reducing the rate of aging of the weight plate, maintaining the normal weight-balancing function of the dumbbell, and further extending the dumbbell's lifespan, allowing it to serve fitness exercises stably for a long time.

[0012] 2. This utility model, by setting a limiting component, makes the installation and position adjustment of the protective component more convenient. The operator only needs to pull the pull column to release the locking block from the inner wall of the bar, and can easily slide the protective component to the appropriate position. Then, by releasing the pull column, the tension spring and the elastic force of the tension spring will re-achieve a stable limiting position. This convenient operation method facilitates the assembly, maintenance, and adjustment of the position of the protective component according to actual needs of the dumbbell, improves the flexibility and maintainability of the dumbbell, ensures that the dumbbell maintains a good structural condition at different stages of use, and provides users with a safe exercise guarantee.

Example

[0019] Please see Figure 1 - Figure 4This utility model provides a technical solution: a dumbbell with an aging-resistant structure, comprising: a bar body 1; a protective component 2, the outer wall of which is slidably connected to the outer walls on both sides of the bar body 1, the protective component 2 being used to wrap the weight of the dumbbell with an elastic material, thereby reducing the damage to the weight from impact; a limiting component 3, the outer wall of which is engaged with the inner walls on both sides of the bar body 1, the limiting component 3 being used to limit the position of the protective component 2 by squeezing it through the engagement with the inner walls of the bar body 1; the protective component 2 includes a weight plate 21, the outer wall of which is fitted with a rubber ring 23, the outer walls on both sides of which are fixedly connected to a sleeve 25 via a rubber plate 22, and the outer walls of the rubber plate 22 are fixedly connected to the outer walls of the sleeve 25, the inner walls of the sleeve 25 being rolledly connected with a damping element. The ball bearings 26, the damping ball bearings 26, can reduce the friction between the sleeve 25 and the rod 1, making the movement of the counterweight 21 smoother and avoiding wear of the parts due to excessive friction. On the other hand, they can also buffer the impact force generated by the counterweight 21 during movement to a certain extent, reducing damage to the counterweight 21 itself and the rod 1. The damping ball bearings 26 are arranged in a ring along the central axis of the sleeve 25. The inner wall of the counterweight 21 is fitted with the outer wall of the sleeve 25. The outer wall of the rubber plate 22 is fixedly connected to the outer wall of the rubber ring 23. The wall of the rubber ring 23 has a shock-absorbing groove 24, and the shock-absorbing groove 24 is arranged in a ring along the central axis of the rubber ring 23. The inner wall of the sleeve 25 is slidably connected to the outer walls on both sides of the rod 1, and the outer walls on both sides of the rod 1 are tumbledly connected to the outer walls of the damping ball bearings 26.

[0020] The limiting component 3 includes a fixed plate 32, a locking block 31 fixedly connected to the outer wall of the fixed plate 32, a pull post 37 slidably connected to the outer wall of the fixed plate 32 through a fixed shell 33, and the inner wall of the fixed shell 33 slidably connected to the outer wall of the pull post 37. A connecting frame 36 is slidably connected to the inner wall of the fixed plate 32, and a tension spring 35 is fixedly connected to the outer wall of the connecting frame 36. In the initial state, the tension spring 35 is in a certain contracted state, applying a corresponding elastic force to the connecting frame 36. The end of the tension spring 35 away from the connecting frame 36 is fixedly connected to the outer wall of the fixed plate 32. A push plate 34 is fixedly connected to the side of the connecting frame 36 close to the fixed plate 32. A tension spring 38 is fixedly connected to the outer wall of the fixed shell 33, and the outer wall of the fixed shell 33 is fixedly connected to the outer wall of the fixed plate 32.

[0021] One end of the tension spring 38 away from the fixed shell 33 is fixedly connected to the outer wall of the pull column 37. The outer wall of the pull column 37 is slidably connected to the inner wall of the locking block 31. The outer wall of the locking block 31 is locked to the inner wall of the rod 1. The outer wall of the rod 1 is in contact with the outer wall of the fixed plate 32. The outer wall of the push plate 34 is in contact with the outer wall of the rubber plate 22. Pulling the pull column 37 causes it to slide within the fixed shell 33 and stretch the tension spring 38. After the pull column 37 slides out of the inner wall of the locking block 31, the locking block 31 retracts and disengages from the inner wall of the rod 1. Then, the locking block 31 moves away from the inner wall of the rod 1, releasing the locking state between the locking block 31 and the inner wall of the rod 1.

[0022] Working principle:

[0023] The dumbbell is mainly composed of a bar body 1, a protective component 2, and a limiting component 3. These components work together to provide good protection for the dumbbell, reducing damage to the counterweight caused by impacts and friction during use. It also features a stable structure and is resistant to aging, thus extending the dumbbell's lifespan and meeting the needs of long-term fitness training.

[0024] The protective component 2 plays a crucial protective role in the dumbbell structure. It mainly includes components such as a counterweight plate 21, a rubber ring 23, a rubber plate 22, a sleeve 25, and damping balls 26. The counterweight plate 21 is the core part of the dumbbell's counterweight. Its outer wall is fitted with a rubber ring 23, which can directly wrap and protect the counterweight plate 21. The outer walls on both sides of the rubber ring 23 are fixedly connected to the sleeve 25 through the rubber plate 22. The rubber plate 22 not only connects the rubber ring 23 and the sleeve 25, but also increases the integrity and stability of the entire protective structure.

[0025] The inner wall of the sleeve 25 is rolled with damping balls 26, which are arranged in a ring along the central axis of the sleeve 25. The inner wall of the sleeve 25 is slidably connected to the outer walls on both sides of the bar 1, and the outer walls on both sides of the bar 1 are rolledly connected to the outer walls of the damping balls 26. During the use of the dumbbell, when lifting and lowering movements cause the counterweight plate 21 to move relative to the bar 1, the sleeve 25 will slide along the outer wall of the bar 1. At this time, the damping balls 26 roll between the sleeve 25 and the bar 1. On the one hand, this can reduce the friction between the sleeve 25 and the bar 1, making the movement of the counterweight plate 21 smoother and avoiding wear of parts due to excessive friction. On the other hand, it can also buffer the impact force generated by the counterweight plate 21 during movement to a certain extent, reducing damage to the counterweight plate 21 itself and the bar 1.

[0026] Meanwhile, the wall of the rubber ring 23 is provided with shock-absorbing grooves 24, and the shock-absorbing grooves 24 are arranged in a ring along the central axis of the rubber ring 23. When the dumbbell is subjected to external impact, such as accidentally falling to the ground or colliding with other objects, the impact force generated by the impact will be transmitted to the rubber ring 23. The shock-absorbing grooves 24 can absorb and disperse these impact forces through their own deformation, further protecting the internal counterweight plate 21 from damage, thereby reducing the damage to the counterweight object caused by the impact and maintaining the normal use function of the dumbbell.

[0027] The limiting component 3 is mainly responsible for limiting the position of the protective component 2 to ensure that the protective component 2 is in a stable state on the rod 1. It consists of components such as a fixing plate 32, a locking block 31, a fixing shell 33, a pull column 37, a connecting frame 36, a tension spring 35, and a tension spring 38.

[0028] The fixing plate 32 serves as the basic fixing structure, and its outer wall is fixedly connected to the locking block 31. The outer wall of the locking block 31 is engaged with the inner wall of the rod 1. The limiting component 3 is fixed to the rod 1 through this engagement method. The outer wall of the fixing plate 32 is slidably connected to the pull column 37 through the fixing shell 33. The inner wall of the fixing shell 33 is slidably connected to the outer wall of the pull column 37, so that the pull column 37 can slide within the fixing shell 33.

[0029] The inner wall of the fixed plate 32 is slidably connected to the connecting frame 36, and the outer wall of the connecting frame 36 is fixedly connected to the tension spring 35. The end of the tension spring 35 away from the connecting frame 36 is fixedly connected to the outer wall of the fixed plate 32. In the initial state, the tension spring 35 is in a certain contracted state, applying a corresponding elastic force to the connecting frame 36. The side of the connecting frame 36 closest to the fixed plate 32 is fixedly connected to the push plate 34, and the outer wall of the push plate 34 is in contact with the outer wall of the rubber plate 22 in the protective assembly 2.

[0030] A tension spring 38 is also fixedly connected to the outer wall of the fixed housing 33. The end of the tension spring 38 away from the fixed housing 33 is fixedly connected to the outer wall of the pull column 37. The outer wall of the pull column 37 is slidably connected to the inner wall of the locking block 31. When it is necessary to install or adjust the position of the protective component 2, the operator pulls the pull column 37. The pull column 37 slides in the fixed housing 33 and stretches the tension spring 38. After the pull column 37 slides out of the inner wall of the locking block 31, the locking block 31 retracts and disengages from the inner wall of the rod 1. Then the locking block 31 moves away from the inner wall of the rod 1, releasing the locking state between the locking block 31 and the inner wall of the rod 1. At this time, the protective component 2 can be slid along the rod 1 to a suitable position.

[0031] After the protective component 2 is positioned, the locking block 31 is slid back into the rod body 1. Then, the pull column 37 is released. The tension spring 38 and tension spring 35 rely on their own elastic restoring force. The tension spring 38 causes the pull column 37 to return to its initial position, thereby pulling the pull column 37 to slide back to the inner wall of the locking block 31, thus opening the locking block 31 and making the locking block 31 lock back into the inner wall of the rod body 1. The tension spring 35 pushes the connecting frame 36 to drive the push plate 34 to apply pressure to the rubber plate 22, so that the protective component 2 is tightly squeezed in the corresponding position, realizing the stable limiting of the protective component 2, preventing the protective component 2 from sliding randomly due to external forces during the use of the dumbbell, and ensuring the stability of the dumbbell structure.

[0032] In daily use, such as when performing dumbbell exercises, when picking up and putting down the dumbbells or performing some strength training movements that cause relative movement of the weight plate 21, the damping ball 26, rubber ring 23, and other components in the protective component 2 work together to reduce friction, buffer impact, and disperse force, protecting the weight plate 21 from damage. Meanwhile, the limiting component 3 always maintains a stable limit on the protective component 2, ensuring that the protective component 2 functions stably and maintaining the stability of the overall dumbbell structure. Even if the dumbbell is occasionally subjected to external impacts or other accidents, the protective component 2 can absorb and resist the impact force due to its structural characteristics, ensuring the normal use of the dumbbell and the integrity of the internal weight structure, extending the service life of the dumbbell, and enabling it to meet the needs of fitness training for a long time.
