Abstract
Description
[Technical Field]
[0001] The present invention relates to the field of sports and fitness equipment, and more particularly to an adjustable weight kettlebell, the weight of which can be adjusted by turning a handle. [Background technology]
[0002] Kettlebells are a popular fitness equipment for power training. It's common to hold the handle with both hands and swing it during training, which allows for more muscle training and promotes healthy and coordinated development of various parts of the body. Traditional kettlebells are one-piece and cannot be adjusted in weight. To accommodate different training intensities and demands, sets of kettlebells with different weights are needed. They are best purchased as a set at fitness centers, but rarely available at home.
[0003] To overcome the problems of fixed, non-adjustable weights and the need to purchase a set of power-driven kettlebells, Chinese Patent Publication No. CN217246498U discloses an adjustable-weight kettlebell. This structure allows kettlebells of different weights to be obtained simply by adjusting the number of internal weights through the insertion position of the latch. A single kettlebell can replace a set of traditional kettlebells, making it more economical and convenient for use in fitness centers and at home, occupying less space, and effectively resolving the above-mentioned problems of traditional kettlebells. However, this structure suffers from the following drawbacks during use. First, each weight block requires a stopper component to be attached to engage with the latch. This makes the weight block structure too complicated, making production and installation inconvenient, and the stopper component can become ineffective. Second, the weight blocks do not have bases, making it easy for the weight blocks to become disorganized during weight adjustment, making it difficult to align them properly. Third, large gaps between the weight blocks result in mechanical collision noises during training, leaving room for further improvement. [Prior art documents] [Patent documents]

[0006] The technical solution adopted by the present invention to solve the above technical problems includes a case, a handle fixed to the case, a plurality of weight pieces, and a base. The case includes an inner and outer case and a weight support frame. The weight support frame is fastened to the inner and outer case, and the weight support frame is provided with hangers corresponding to the weight pieces. The weight pieces are stacked in a line and positioned, and the weight pieces are provided with arc-shaped hooks corresponding to the hangers. The arc-shaped hooks on the weight pieces are arranged in order from long to short from top to bottom to form a weight adjustment gear. A center positioning table is provided on the base, and a turntable is provided between the base and the center positioning table. The weight pieces are positioned and placed on the center positioning table, and the case is positioned and placed on the turntable to cover the weight pieces. When the handle rotates the case, the hangers on the weight support frame slide under the arc-shaped hooks of the corresponding weight pieces to adjust the weight.
[0007] In another aspect of the present invention, a weight locking device is provided within the case, including a guide rod slidably mounted on the case, weight locking stops fixed to the tops of the guide rods, and locking stopper springs that apply elastic force to the weight locking stops. The top weight has anti-rotation positioning grooves that engage with the weight locking stops, and the number of anti-rotation positioning grooves matches the number of weight adjusting gears. When the case is placed on the turntable, the guide rod abuts against the turntable, causing the weight locking stops to disengage from their corresponding anti-rotation positioning grooves, unlocking the case and allowing the weight to be rotated relative to the weight. When the handle is lifted, the guide rod disengages from the turntable, and the locking stopper springs engage and lock the weight locking stops in their corresponding anti-rotation positioning grooves, preventing the weight from rotating relative to the case.
[0008] In a further solution of the present invention, a bottom cover is fixed to the turntable, and a turntable stopper locking device is installed between the turntable and the bottom cover, the turntable stopper locking device including a stopper locking piece, a locking piece spring, a detent, and a detent spring, the center positioning base is installed with a stopper groove that fits the weight adjusting gear, the stopper locking piece is installed with a locking groove and a locking head that engages with the stopper groove to lock, the upper part of the detent is installed with a straight pin portion that is movable relative to the locking groove, and the lower part is installed with a locking portion that fits into the locking groove and is immovable, the stopper locking piece is installed horizontally on the turntable via the locking piece spring, the detent is installed in the locking groove and is installed vertically between the turntable and the bottom cover via the detent spring, and the straight pin portion of the detent protrudes from the straight pin hole of the turntable to engage with the case. When the case is pressed against the straight pin, the detent moves downward and the stopper lock piece moves outward relative to the straight pin to unlock the turntable. At this time, when the handle is turned, the stopper lock piece moves from the previous gear groove to the next gear groove after resisting the elastic force of the lock piece spring, causing the case and turntable to rotate synchronously and achieving weight adjustment. When the case moves away from the straight pin, the detent jumps upward due to the elastic force of the detent spring, and the lock piece engages with the lock groove to immobilize the stopper lock piece, and the lock head engages with the stopper groove to lock the turntable.
[0009] A further solution of the present invention is that a central jumper is fixed to the weight support frame, a central positioning groove is provided on the top of the weight piece, a weight piece positioning block is provided on the bottom, and a weight piece positioning groove is provided on the central positioning table, and the central jumper on the weight support frame is rotated and engaged with the central positioning groove of the topmost weight piece, and the weight piece positioning block of the bottommost weight piece is positioned and engaged with the weight piece positioning groove on the central positioning table, and the weight pieces are positioned by engaging with the central positioning groove via the weight piece positioning block.
[0010] In a further solution of the present invention, the turntable is provided with a case positioning table, and the case is provided with a positioning guide member that is engaged with the case positioning table for positioning.

By continuing to rotate the handle 1 in the above steps, weight adjustments from the second gear to the sixth gear can be achieved, and this process is omitted here. FIG. 9 shows that the weight adjustment is in the gear 6 position, all hangers 21 are engaged with the corresponding arc-shaped hooks 11, and the weight indicating arrows 15 are aligned with the weight indicating windows 1 where the weight of gear 6 is 20 kg.
[0024] Once the kettlebell weight adjustment is complete, lifting handle 1 releases guide rod 22 from turntable 6. Weight piece locking stopper 25 automatically engages with corresponding anti-rotation positioning groove 10 under the action of the elastic force of locking stopper spring 24, locking weight piece 3. Weight piece 3 cannot rotate relative to the case, ensuring a reliable connection between weight piece 3 and case during kettlebell training. At the same time, the case releases base 7, and detent 28 springs upward under the action of the elastic force of detent spring 29. Locking part 38 engages with locking groove 34, immobilizing stopper locking piece 26. Locking head 37 of stopper locking piece 26 locks into gear groove 39 of the gear corresponding to center positioning base 5, locking turntable 6 and ensuring that the gear indication matches the weight adjustment.
