[0033] The following will be combined with the implementation of the utility model to clearly and completely describe the technical solutions in the implementation of the utility model. Obviously, the described implementation is only a part of the implementation of the utility model, not all of the implementations. Based on the implementation of the utility model, all other implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] like Figure 1-5 As shown, the handheld fitness trainer of the present invention comprises a grip 1 , a buffer column 2 , an elastic strip 3 and a weight 4 .

[0035] The hand grip 1 includes a first grip portion 11, which is in a straight tube shape and has an open end. The hand grip 1 is the main connecting component of the trainer. The first grip portion 11 arranged thereon can be used by the user as a holding part when performing battle rope training. The straight tube shape of the first grip portion 11 can be convenient for the user to hold and swing.

[0036] The buffer column 2 is inserted into the open end of the first grip portion 11 and is relatively fixed to the grip 1. The buffer column 2 is the main buffer component in the present embodiment. The portion of the buffer column 2 inserted into the first grip portion 11 is completely in contact with the inner wall of the first grip portion 11. Different from the prior art, the buffer column 2 is fixed to the first grip portion 11 by gluing. Specifically, a strong instant adhesive of silicone can be used to bond and fix the buffer column 2 to the first grip portion 11. Fixing by gluing can give the buffer column 2 a certain elastic displacement space, thereby improving the structural stability and preventing the buffer column 2 from being subjected to excessive local force and affecting its service life.

[0037] One end of the elastic strip 3 extends into the buffer column 2 and is fixed to the buffer column 2. When the hand grip 1 is swung, the other end of the elastic strip 3 can swing back and forth. The buffer column 2 is used to buffer the vibration transmitted from the elastic strip 3 to the hand grip 1. The elastic strip 3 can be set in a slat shape or a cylindrical shape. The slat shape of the elastic strip 3 can fix the swinging direction of the elastic strip 3 and improve the stability of the swinging. The elastic strip 3 is set as a cylindrical strip, which can make the swinging direction of the elastic strip 3 more diverse and make it have certain operability. It can be used in some specially designed aerobics and other usage scenarios. Specifically, the elastic strip 3 is preferably a glass fiber strip. The glass fiber strip has good mechanical strength and can ensure safety during the swinging process. At the same time, its lightweight and corrosion-resistant characteristics can further improve the service life of the trainer.

[0038] During the swinging of the elastic strip 3, since the elastic strip 3 is indirectly fixed to the hand grip 1 through the buffer column 2, the force on the elastic strip 3 will be transmitted to the hand grip 1 through the buffer column 2. During the transmission process, the buffer column 2 will deform to buffer the pressure, especially the sudden pressure, which will be transmitted to the user's hand more smoothly, thereby reducing the vibration and impact generated by the hand grip 1 during use and providing a more comfortable use experience.

[0039] The counterweight 4 is fixed on the end of the elastic strip 3 away from the first gripping portion 11. The counterweight 4 is used to increase the swing amplitude of the elastic strip 3. Since the elastic strip 3 has limited self-weight, the swing amplitude and the force generated by the swing at the end away from the grip 1 are relatively small. The counterweight 4 can increase the pressure generated during the swinging of the elastic strip 3 by increasing the weight at the end of the elastic strip 3. After the pressure increases, the swing amplitude of the elastic strip 3 will also increase accordingly, so that the elastic strip 3 can accumulate more pressure through deformation, thereby increasing the training intensity of the user.

[0040] As a preferred embodiment, the buffer column 2 includes a stabilizing portion 21 and a sealing portion 22. The stabilizing portion 21 is inserted into the first gripping portion 11 and fixed to the first gripping portion 11. The stabilizing portion 21 is cylindrical and is directly equal to the inner diameter of the first gripping portion 11. The sealing portion 22 is integrally formed with the stabilizing portion 21 and fixed on the opening side of the first gripping portion 11 to completely close the opening of the first gripping portion 11. The elastic strip 3 passes through the sealing portion 22 and extends into the stabilizing portion 21.

[0041] During the production process, the stabilizing portion 21 and the sealing portion 22 of the buffer column 2 are integrally injection molded through a mold. It should be noted that during the injection molding process, a position for installing the elastic strip 3 needs to be reserved. During assembly, the outside of the stabilizing portion 21 is coated with glue and inserted into the first gripping portion 11, and the sealing portion 22 is used to seal the opening side of the first gripping portion 11. The sealing portion 22 is arranged in a truncated cone shape, specifically, it is arranged as two coaxial circles, one large and one small, and the two circles are connected by an arc. The arc rotates around the coaxis to form an arc surface to connect the two circles to form the sealing portion 22. The diameter of the large circle is larger than the outer diameter of the first gripping portion 11, and the diameter of the small circle is not smaller than the inner diameter of the first gripping portion 11. The sealing portion 22 has a side of the large circle fixed on the opening side of the first gripping portion 11, thereby completely blocking the first gripping portion 11.

[0042] As a preferred embodiment, the hand grip 1 also includes a second grip portion 12 and a third grip portion 13, one end of the second grip portion 12 is fixed to the first grip portion 11, and the third grip portion 13 is fixed to the other end of the second grip portion 12, and the first grip portion 11, the second grip portion 12 and the third grip portion 13 are integrally formed.

[0043] By providing three grips on the hand grip 1, the user can hold one of the first grip 11, the second grip 12 and the third grip 13 when performing push-up training, and make the other two contact the ground, thereby realizing push-up training through the hand grip 1. It should be noted that the axes of the first grip 11, the second grip 12 and the third grip 13 are parallel to each other and are not located on the same plane. If the three grips are all located on the same plane, the user will not be able to grab one of them for support when the hand grip 1 is placed on the ground.

[0044] As a preferred embodiment, the axes of the first grip 11, the second grip 12 and the third grip 13 are respectively located at the three corners of the same equilateral triangle. The axes of the first grip 11, the second grip 12 and the third grip 13 are equilaterally arranged, which allows the user to have better stability when holding any grip, thereby improving the safety of push-up training.

[0045] In this embodiment, the hand grip 1 also includes two bending portions 14, wherein two ends of one of the bending portions 14 are respectively fixed to the first grip 11 and the second grip 12, and two ends of the other bending portion 14 are respectively fixed to the second grip 12 and the third grip 13. By setting the two bending portions 14, the first grip 11, the second grip 12 and the third grip 13 are connected in one piece, so that the hand grip 1 can be integrally bent and formed using a pipe fitting, thereby reducing the steps and costs required for production. Specifically, the hand grip 1 uses a straight pipe and performs bending operations on both sides to form two bending portions 14, and the first grip 11, the second grip 12 and the third grip 13 are respectively formed between the two bending portions 14 and at the ends.

[0046] As a preferred embodiment, a sponge cover 5 is further provided, and the sponge cover 5 is sleeved on the outside of the hand grip 1. The sponge cover 5 is used to cushion and disperse the force on the user's hand. Since the hand grip 1 is formed by bending a straight tube as a whole, it needs to have strong rigidity to avoid deformation during use. However, its strong rigidity will also cause uneven pressure on the user's hand when the user directly holds it, resulting in problems such as hand slippage due to the lack of a flexible component as an intermediate buffer, and will also affect the user experience. The sponge cover 5 can be sleeved on the outside of the hand grip 1, and the user can increase the contact area between the hand and the hand grip 1 through the sponge cover 5, and reduce the vibration transmission from the hand grip 1 to the hand, which can avoid problems such as user hand slippage and can effectively improve the user experience.

[0047] Specifically, the buffer column 2 and the counterweight 4 are both silicone components. Silicone, also known as silicone rubber, is a very useful material, mainly because of its physical and chemical properties, which makes it perform well in various applications, especially when used as a buffer component. Silicone has good elasticity and flexibility, which can absorb and alleviate shock and vibration. In addition, its tear resistance and compression resistance are also excellent, which enhances its durability as a buffer material. Silicone has good resistance to water and most chemicals, so it is not easy to age or degrade when it comes into contact with liquids such as sweat during training.

[0048] In this embodiment, the outer surface of the counterweight 4 is formed by splicing a number of curved surfaces to form an ellipsoidal sphere. The non-angular design of the counterweight 4 can avoid touching the human body and causing harm during the swinging process. Combined with the fact that the counterweight 4 is made of silicone, the safety during use can be effectively improved.

[0049] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
