Description

Technical Field

[0001] This utility model belongs to the field of fitness equipment technology, specifically relating to a vibrating kettlebell. Background Technology

[0002] Kettlebells are a common and simple piece of fitness equipment, primarily used to improve physical fitness. Unlike dumbbell and barbell training, kettlebell training is more effective at comprehensively enhancing overall explosive power, which is why it has long been favored by fighters and martial artists.

[0003] However, traditional kettlebells have a fixed weight, requiring trainees to prepare a set of kettlebells of different weights to meet their training needs. While this satisfies the trainee's needs, it is extremely inconvenient to carry around various kettlebells. To address this, existing technology discloses a kettlebell with adjustable weight, achieved by setting different numbers of counterweights. Although this kettlebell fulfills the function of weight adjustment, the counterweights are fixed. When the kettlebell needs to vibrate, the fixed position of the counterweights prevents it from vibrating.

[0004] To enable the kettlebell to vibrate, a counterweight can be slidably connected to the handle, meaning the counterweight is replaced by a slider. When the slider moves to its limit position under inertia, it creates a vibration effect. Since the stroke of the slider is fixed, the vibration amplitude of this type of vibrating kettlebell cannot be adjusted. Utility Model Content

[0005] This invention provides a vibrating kettlebell, which aims to solve the problem that the vibration amplitude of the slider in existing vibrating kettlebells cannot be adjusted.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A vibrating kettlebell includes a handle and a base. A slider is disposed between the handle and the base. An adjustment component for adjusting the vibration amplitude of the slider is also disposed between the handle and the base. The adjustment component adjusts the vibration amplitude of the slider by adjusting the distance of the slider relative to the handle and adjusting the distance of the slider relative to the base. A first elastic element is disposed between the slider and the handle, and a second elastic element is disposed between the slider and the base.

[0008] The adjustment assembly includes an adjustment rod rotatably connected to the base, a sliding sleeve provided on the adjustment rod, the sliding sleeve being circumferentially fixed relative to the adjustment rod and sliding along the axial direction of the adjustment rod, the sliding sleeve being provided with an external thread, and the slider being provided with a threaded hole that mates with the external thread. The vibration amplitude of the slider is adjusted by operating the adjustment rod to adjust the distance of the slider relative to the handle.

[0009] A further improved solution: the cross-sectional shape of the adjusting rod is polygonal, and the sliding sleeve is provided with a sliding hole that mates with the adjusting rod.

[0010] Based on the above technical solution: the polygonal cross-section adjustment rod, in conjunction with the sliding hole, effectively prevents accidental circumferential movement of the sliding sleeve on the adjustment rod. This design ensures that the sliding sleeve can only slide along the axial direction of the adjustment rod and will not deviate from the predetermined path during rotation, thus guaranteeing the accuracy and stability of the adjustment. Compared to circular or other shapes, the polygonal cross-section adjustment rod is easier to grip and rotate with fingers or tools. This allows users to apply more even force when adjusting the slider position, making it easier to achieve fine adjustment control. The polygonal cross-section design also increases the torsional strength of the adjustment rod. When pressure or torque is applied to the sliding sleeve, the polygonal structure can better resist deformation and breakage, thereby extending the service life of the vibrating kettlebell.

[0011] A further improved solution: the upper end of the adjusting rod is fixed to the handle, and the lower end of the adjusting rod is rotatably connected to the base.

[0012] Based on the above technical solution: Since the upper end of the adjusting rod is fixed to the handle and the lower end is rotatably connected to the base, this structure provides a stable support point for the slider and its vibration amplitude adjustment. Users can change the position of the sliding sleeve by rotating the lower end of the adjusting rod, thereby adjusting the vibration amplitude of the slider, while maintaining the overall stability of the kettlebell throughout the adjustment process. Fixing the upper end of the adjusting rod to the handle makes it easier for users to hold and control the kettlebell during operation. Simultaneously, the rotatable connection design at the lower end of the adjusting rod allows users to achieve precise adjustments through simple rotation, improving operational convenience and efficiency. This design also helps enhance the overall structural stability of the vibrating kettlebell. As a key component connecting the handle and the base, the fixing and rotatable connection of the adjusting rod ensures that the kettlebell maintains structural integrity and stability during vibration, thereby extending the product's service life.

[0013] A further improved solution: The slider includes a housing, a connecting cylinder is provided on the housing, the connecting cylinder is sleeved on the adjusting rod, a connecting block is provided inside the connecting cylinder, a screw hole is provided on the connecting block, and the screw hole penetrates the connecting block.

[0014] Based on the above technical solution: the housing, as the main structural part of the slider, plays a role in protecting the internal components. It prevents external factors such as dust and moisture from entering the slider and affecting its normal operation and lifespan. The connecting block is located inside the connecting cylinder, and the screw hole passes through the connecting block. The screw hole mates with the external thread of the sliding sleeve on the adjusting rod. By rotating the adjusting rod, the sliding sleeve can be driven to move on the adjusting rod, thereby pushing or pulling the connecting block and the entire slider on the adjusting rod through the threaded connection. This design achieves precise adjustment of the slider position, thus controlling the amplitude of the slider's vibration.

[0015] A further improved solution: A counterweight is provided inside the slider. The counterweight is ring-shaped, and its axis is coaxial with the axis of the slider.

[0016] Based on the above technical solution: the design of the ring-shaped counterweight helps maintain the balance of the slider during vibration. Due to its shape and distribution characteristics, the ring-shaped counterweight can evenly distribute the mass, reducing the eccentric force generated during vibration, making the slider's vibration smoother and more controllable. The presence of the counterweight increases the mass of the slider, thereby enhancing the vibration effect. When the slider slides on the adjusting rod and impacts the handle or base, the greater mass means a stronger impact force and a more pronounced vibration effect, which helps improve training effectiveness. The axis of the counterweight is coaxial with the axis of the slider; this design ensures that the counterweight will not shift or rotate relative to the slider during vibration. This stability is crucial for maintaining the overall structural integrity and vibration performance of the kettlebell.

[0017] A further improved solution: The lower end of the first elastic element is fixed to the housing via a connecting assembly.

[0018] Based on the above technical solution: the first elastic element serves as an elastic connection between the slider and the handle, and its lower end is firmly fixed to the housing via a connecting component, ensuring stable elastic support for the slider during vibration. This stability is crucial for maintaining the slider's vibration trajectory and amplitude. The design of the connecting component makes the installation and replacement of the first elastic element more convenient. Users can install or replace the first elastic element through simple operations, such as loosening or tightening the screws of the connecting component, without the need for complex disassembly of the entire slider or kettlebell. Through the connecting component, users can more flexibly select first elastic elements with different elastic properties. For example, depending on training needs, users can choose a harder or softer elastic element to adjust the slider's vibration characteristics and training effect.

[0019] A further improved solution: The connecting assembly includes a connecting seat, which is inserted into the housing. The connecting seat is also provided with a connecting ring, and a positioning cavity is formed between the connecting ring and the housing. A portion of the first elastic element is located in the positioning cavity.

[0020] Based on the above technical solution: the connecting seat is inserted into the housing, providing a stable support point for the first elastic element. The insertion fit between the connecting seat and the housing ensures that the connecting seat will not loosen or fall off during vibration, thus guaranteeing the stable operation of the first elastic element. The connecting ring makes it easier to install and position the first elastic element on the housing. By adjusting the position of the connecting ring, it can be ensured that a portion of the first elastic element is accurately located within the positioning cavity, thereby achieving precise assembly and positioning.

[0021] A further improved solution: The connecting seat is provided with a hook, and the housing is provided with a locking hole that cooperates with the hook.

[0022] Based on the above technical solution, the engagement of the hook and the locking hole provides a robust connection method, ensuring that the connector is firmly fixed to the housing. This connection method effectively prevents loosening or detachment between the connector and the housing during vibration, thus guaranteeing the overall stability and safety of the vibrating kettlebell. The design of the hook and the locking hole makes the installation and removal of the connector more convenient. Users simply align the hook with the locking hole and push it in to achieve a fixed connection between the connector and the housing. Similarly, when users need to remove the connector, they simply pull out the hook to complete the removal operation. This design greatly improves the efficiency of installation and removal. The engagement of the hook and the locking hole also enhances the overall structural strength of the vibrating kettlebell. The tight fit between the hook and the locking hole resists the stress and fatigue generated during vibration, thereby extending the service life of the vibrating kettlebell.

[0023] A further improved solution: The upper end of the first elastic element is fixed to the handle by an upper connecting plate, the upper connecting plate is fixed to the handle by screws, and a portion of the first elastic element is located between the upper connecting plate and the handle.

[0024] Based on the above technical solution: the upper end of the first elastic element is firmly fixed to the handle via the upper connecting plate, a design that ensures stable vibration transmission. As an intermediary component, the upper connecting plate not only provides sufficient connection area to enhance connection stability but also disperses the stress generated during vibration through its structural characteristics, thereby protecting the first elastic element and the handle from damage. The upper connecting plate is tightly fixed to the handle with screws, a fastening method that further enhances the reliability of the connection. Screws, as commonly used fasteners, have advantages such as simple structure, strong connection, and easy disassembly, making them very suitable for fitness equipment like vibrating kettlebells that need to withstand frequent vibration and impact.

[0025] A further improved solution: The upper end of the second elastic element is fixed to the slider by a lower connecting plate, the lower connecting plate is fixed to the slider by screws, a part of the second elastic element is located between the lower connecting plate and the slider, the lower end of the second elastic element is fixed to the base by a positioning ring, the positioning ring is fixed to the base by screws, and a part of the second elastic element is located between the positioning ring and the base.

[0026] Based on the above technical solution: the second elastic element is fixed to the slider and the base respectively via the lower connecting plate and the positioning ring, forming a stable elastic support structure. This design ensures that vibrations can be transmitted efficiently and stably along the set path, thereby improving training effectiveness. The lower connecting plate and the positioning ring are fastened with screws, further enhancing the stability of the structure and preventing components from loosening or falling off during vibration. The screw connection method makes the installation, adjustment, and replacement of the lower connecting plate, positioning ring, and second elastic element simple and easy. Users can easily maintain or adjust the kettlebell as needed to meet different training requirements.

[0027] The beneficial effects of this utility model are as follows:

[0028] This invention allows users to easily adjust the vibration amplitude through precise control of the adjustment components, meeting diverse training needs. This feature makes the vibrating kettlebell more flexible and practical in the fitness field. The vibration function stimulates deeper muscle contraction and relaxation, accelerates blood circulation, and improves training efficiency. Simultaneously, the adjustable vibration amplitude allows trainees to perform more precise and effective training targeting specific muscle groups.

[0029] Traditional kettlebells with fixed weight and vibration amplitude often fail to meet the needs of all trainees. Vibrating kettlebells, however, significantly enhance user experience and satisfaction by introducing an adjustable mechanism. Whether you're a beginner or a seasoned fitness enthusiast, you can find a training mode and vibration amplitude that suits you. Despite its adjustable vibration amplitude, the vibrating kettlebell maintains a compact and lightweight design. This allows trainees to easily carry and store the kettlebell for training anytime, anywhere. Attached Figure Description
