Description

Technical Field

[0001] This utility model relates to the field of fitness dumbbell technology, and more specifically to a non-slip fitness dumbbell. Background Technology

[0002] As a basic and core strength training tool, dumbbells are valued for providing users with controllable resistance to achieve various fitness goals such as muscle strengthening, shaping, and functional improvement. However, traditional dumbbells have the risk of slipping due to insufficient grip stability during long-term or high-intensity training. Traditional dumbbell handles are mostly treated with smooth metal electroplating or spraying to increase the surface friction coefficient. When users perform heavy presses, explosive movements, or prolonged training sessions and their palms sweat, the friction between the palm and the handle decreases sharply. Sweat acts as a lubricant, greatly weakening the reliability of the grip. At this time, users have to expend extra neuromuscular control resources to grip the dumbbells tightly. This not only accelerates the fatigue of the forearm and hand muscles, but also seriously distracts the training attention from the target large muscle groups, reducing training efficiency. Decreased grip strength or sudden slippage can easily cause the dumbbells to fall accidentally, posing a serious safety hazard to the trainee and those around them. Modern dumbbells do not provide enough friction, so users need to use more grip strength to hold them, and they are very easy to cause injury when they slip. Utility Model Content

[0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides a non-slip fitness dumbbell to solve the problems existing in the background art.

[0004] This utility model provides the following technical solution: a non-slip fitness dumbbell, including a dumbbell connecting rod, dumbbell plates are movably snapped onto both sides of the dumbbell connecting rod, a non-slip mechanism is fixedly connected to the middle of the side of the dumbbell connecting rod, and a fixing mechanism is movably connected to the side of the dumbbell connecting rod; the non-slip mechanism includes a fixing cylinder fixedly connected to the side of the dumbbell connecting rod, a raised ball fixedly connected to the side of the fixing cylinder, a through hole between two adjacent raised balls along the axis of the fixing cylinder, rubber rings fixedly connected to both ends of the side of the fixing cylinder, a rubber pad fixedly connected to the side of the two rubber rings that are close to each other, and the inner side of the rubber pad and the rubber ring is fixedly connected to the outer side of the fixing cylinder.

[0005] Furthermore, the connection between the fixing mechanism and the dumbbell connecting rod is located on both sides of the anti-slip mechanism, and the connection between the fixing mechanism and the dumbbell connecting rod is located inside the dumbbell plates on both sides of the dumbbell connecting rod.

[0006] Furthermore, the raised balls and the through holes are distributed at equal angles along the side of the fixed cylinder, and when the raised balls and the through holes are distributed at equal angles, the rubber pad is located between the raised balls and the through holes.

[0007] Furthermore, the fixing mechanism includes a rotating ring that is movably sleeved with the side of the dumbbell connecting rod. A connecting belt is fixedly connected to the side of the rotating ring, and a forked belt is fixedly connected to the side of the connecting belt away from the rotating ring. An upper forked belt is fixedly connected to the top of the side of the forked belt, a lower forked belt is fixedly connected to the bottom of the side of the forked belt, and an upper fixing belt is fixedly connected to the bottom of the upper forked belt away from the side of the forked belt.

[0008] Furthermore, the upper fixing strap is fixedly connected to both sides with first adhesive tape, the lower branch strap is fixedly connected to the top of the side away from the branch strap with a lower fixing strap, the lower fixing strap is fixedly connected to both sides with lower adhesive tape, and the connecting strap is movably connected to the side with an adjusting buckle, the adjusting buckle adjusting the length of the connecting strap.

[0010] The technical effects and advantages of this utility model are as follows: 1. This utility model, by providing a fixed cylinder, raised balls, through holes, and rubber pads, ensures that when gripping the dumbbell connecting rod, the hand makes overall contact with the anti-slip mechanism. The fixed cylinder within the anti-slip mechanism is equipped with raised balls and through holes. The raised balls increase friction, while the through holes temporarily trap sweat, reducing the surface area for sweat flow and thus increasing friction. The rubber pads and raised balls are interwoven, further enhancing friction. The rubber pads are fixedly connected to the fixed cylinder to prevent mutual rotation during use.

[0011] 2. This utility model features a connecting strap, an upper fixing strap, a lower fixing strap, and an upper dividing strap. The wrist is placed between the upper and lower fixing straps, and the wrist is secured by a first adhesive tape and a lower adhesive tape that bond together. Adjusting the adjusting buckle changes the length of the connecting strap, ensuring that the connecting strap is taut when gripping the anti-slip mechanism. This limits the distance between the dumbbell connecting rod and the wrist, preventing it from falling off when the grip is loose, thus improving safety. Attached Figure Description

[0017] 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. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0018] Reference Figure 1 and Figure 2 This utility model provides a non-slip fitness dumbbell, including a dumbbell connecting rod 1, dumbbell plates 2 movably snapped onto both sides of the dumbbell connecting rod 1, a non-slip mechanism 3 fixedly connected to the middle of the side of the dumbbell connecting rod 1, and a fixing mechanism 4 movably connected to the side of the dumbbell connecting rod 1. The connection between the fixing mechanism 4 and the dumbbell connecting rod 1 is located on both sides of the non-slip mechanism 3, and the connection between the fixing mechanism 4 and the dumbbell connecting rod 1 is located inside the dumbbell plates 2 on both sides of the dumbbell connecting rod 1.

[0019] In this embodiment, the fixing mechanism 4 is located on both sides of the anti-slip mechanism 3 and inside the dumbbell plate 2. Therefore, the fixing mechanism 4 will not interfere with the anti-slip mechanism 3, ensuring that the anti-slip mechanism 3 can increase friction. The fixing mechanism 4 is connected to both sides of the anti-slip mechanism 3, which improves the stability of the fixing mechanism 4 when connected.

[0020] Reference Figure 2 and Figure 3The anti-slip mechanism 3 includes a fixed cylinder 301 fixedly connected to the side of the dumbbell connecting rod 1. A raised ball 302 is fixedly connected to the side of the fixed cylinder 301. A through hole 303 is opened between two adjacent raised balls 302 along the axis of the fixed cylinder 301. Rubber rings 304 are fixedly connected to both ends of the side of the fixed cylinder 301. A rubber pad 305 is fixedly connected to the side of the two rubber rings 304 that are close to each other. The inner side of the rubber pad 305 and the rubber rings 304 is fixedly connected to the outer side of the fixed cylinder 301. The raised balls 302 and the through hole 303 are distributed at equal angles along the side of the fixed cylinder 301. When the raised balls 302 and the through hole 303 are distributed at equal angles, the rubber pad 305 is located between the raised balls 302 and the through hole 303.

[0021] In this embodiment, the protruding structure of the hole 303 can increase friction and prevent slippage. The hole 303 can also accommodate sweat or impurities, preventing them from reducing friction. A rubber pad 305 is provided between adjacent protruding balls 302, which further increases friction. During training, the rubber pad 305, the fixed cylinder 301, and the dumbbell connecting rod 1 are fixedly connected, so they will not rotate relative to each other, ensuring the safety of the user.

[0022] Reference Figure 2 and Figure 4 The fixing mechanism 4 includes a rotating ring 401 that is movably sleeved with the side of the dumbbell connecting rod 1. A connecting belt 402 is fixedly connected to the side of the rotating ring 401. A forked belt 403 is fixedly connected to the side of the connecting belt 402 away from the rotating ring 401. An upper forked belt 404 is fixedly connected to the top of the side of the forked belt 403. A lower forked belt 407 is fixedly connected to the bottom of the side of the forked belt 403. An upper fixing belt 405 is fixedly connected to the bottom of the upper forked belt 404 away from the side of the forked belt 403. The two sides of the upper fixing belt 405 are fixedly... A first adhesive tape 406 is fixedly connected. A lower fixing tape 408 is fixedly connected to the top of the lower branch tape 407 away from the side of the branch tape 403. Lower adhesive tapes 409 are fixedly connected to both sides of the lower fixing tape 408. An adjusting buckle 410 is movably connected to the side of the connecting tape 402. The adjusting buckle 410 adjusts the length of the connecting tape 402. A first limiting ring 411 and a second limiting ring 412 are movably connected to both sides of the rotating ring 401. The inner sides of the first limiting ring 411 and the second limiting ring 412 are fixedly connected to the side of the dumbbell connecting rod 1.

[0023] In this embodiment, after the wrist is placed between the upper fixing strap 405 and the lower fixing strap 408, the hook side of the first adhesive tape 406 is bonded to the inner rough side of the lower adhesive tape 409, thereby fixing the wrist within the upper fixing strap 405, the first adhesive tape 406, the lower fixing strap 408, and the lower adhesive tape 409. After fixing the wrist, the hand grips the anti-slip mechanism 3, adjusts the rotating ring 401, and adjusts the adjusting buckle 410 to change the length of the connecting strap 402, so that when the hand grips the anti-slip mechanism 3, the connecting strap 402 and the upper split strap 404 are both in a taut state. At this time, during training, the connecting strap 402 and the upper split strap 404 are in a taut state, restricting the position of the dumbbell connecting rod 1 and the dumbbell plate 2, and preventing the dumbbell connecting rod 1 from slipping. The first limiting ring 411 and the second limiting ring 412 respectively limit the two sides of the rotating ring 401. To prevent the rotating ring 401 from moving on the side of the dumbbell connecting rod 1, the rotating ring 401 can only rotate on the side of the dumbbell connecting rod 1.

[0024] The working principle of this utility model is as follows: In use, the wrist is placed between the upper fixing strap 405 and the lower fixing strap 408. The first adhesive tape 406 adheres to the wrist, and then the lower adhesive tape 409 is attached to the side of the first adhesive tape 406. At this time, the hook surface of the first adhesive tape 406 adheres to the rough surface of the inner side of the lower adhesive tape 409, thereby fixing the wrist within the upper fixing strap 405, the first adhesive tape 406, the lower fixing strap 408, and the lower adhesive tape 409. After fixing the wrist, the hand grips the anti-slip mechanism 3 and adjusts... The length of the connecting strap 402 is changed by adjusting the rotating ring 401 and adjusting the adjusting buckle 410, so that when the hand grips the anti-slip mechanism 3, both the connecting strap 402 and the upper strap 404 are in a taut state. At this time, when training, the connecting strap 402 and the upper strap 404 are in a taut state, which restricts the position of the dumbbell connecting rod 1 and the dumbbell plate 2, and can prevent the dumbbell connecting rod 1 from slipping. During training, the rotating ring 401 can rotate on the side of the dumbbell connecting rod 1 to ensure that the user can train conveniently. When the user holds the anti-slip mechanism 3, the fixed cylinder 301 inside the anti-slip mechanism 3 has raised balls 302 and through holes 303 on its surface. The raised structure of the through holes 303 can increase friction and prevent slipping, while the through holes 303 can accommodate sweat or impurities, preventing sweat or impurities from reducing friction. A rubber pad 305 is provided between adjacent raised balls 302, which further increases friction. The rubber pad 305, the fixed cylinder 301, and the dumbbell connecting rod 1 are all fixedly connected. Therefore, during training, the rubber pad 305, the fixed cylinder 301, and the dumbbell connecting rod 1 will not rotate relative to each other, ensuring the user's safety.

[0025] In conclusion, the above are merely preferred embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
