[0029] The connecting component 2 includes an inner sleeve rod 201 inserted into the dumbbell grip 1, the outer side of the inner sleeve rod 201 is located on the outer side of the dumbbell grip 1, and both sides of the inner sleeve rod 201 are threadedly connected with a screw rod 202. Both sides of the dumbbell grip 1 are provided with positioning sleeves 203, the positioning sleeves 203 are inserted into the outer side of the inner sleeve rod 201, the positioning sleeves 203 are located on the outer side of the screw rod 202, and the outer side of the positioning sleeve 203 is fixedly connected with a connecting sleeve 204, the connecting sleeve 204 is located on the outer side of the screw rod 202, and the connecting sleeve 204 is located on the inner side of the counterweight block 301.

[0030] In this embodiment, the inner sleeve rod 201 in the connecting assembly 2 is inserted into the dumbbell grip 1, and the outer side of the inner sleeve rod 201 is located on the outer side of the dumbbell grip 1. The inner sleeve rod 201 is threadedly connected to the two sides with a screw rod 202. The length of the inner sleeve rod 201 can be adjusted by rotating the screw rod 202 to adapt to different numbers and sizes of counterweights 301. Positioning sleeves 203 are provided on both sides of the dumbbell grip 1. The positioning sleeves 203 are inserted into the outer side of the inner sleeve rod 201 and are located on the outer side of the screw rod 202. The outer side of the positioning sleeve 203 is fixedly connected with a connecting sleeve 204. The connecting sleeve 204 is located on the outer side of the screw rod 202 and the counterweight 3 01, and then, the user places the counterweight assembly 3 on the outside of the connecting sleeve 204, and makes the counterweight assembly 3 located on the outside of the screw rod 202 to achieve fixation, so that the counterweight block 301 of the counterweight assembly 3 is firmly fixed on the dumbbell grip 1. When it is necessary to increase the counterweight, the counterweight assembly 3 is removed, and then the counterweight block 301 of the same batch is replaced and placed on the outside of the connecting sleeve 204 and the screw rod 202, and then the counterweight assembly 3 is connected to the screw rod 202 and fixed to the connecting sleeve 204. In this way, the user can quickly adjust the weight of the dumbbell according to his needs and realize a variety of counterweight options.

[0031] Specifically, such as Figure 4 As shown, the inner side of the counterweight block 301 is fixedly connected to an inner tapered sleeve 302 , and the outer side of the inner tapered sleeve 302 is provided with threads.

[0032] Specifically, such as Figure 4 As shown, a screw hole 303 is provided inside the inner cone sleeve 302 , and the screw hole 303 is located outside the screw rod 202 .

[0033] Specifically, such as Figure 4 As shown, a screw 304 is provided inside the inner cone sleeve 302 , and the inner side of the screw 304 is threadedly connected to the outer side of the screw rod 202 .

[0034] In this embodiment: when the counterweight needs to be adjusted, after rotating the screw rod 202 to adjust the position and length of the inner sleeve rod 201, the counterweight block 301 with the inner tapered sleeve 302 is put on the connecting sleeve 204, and the inner tapered sleeve 302 is initially contacted and positioned with the connecting sleeve 204 through the outer thread, and the internal screw hole 303 is aligned with the screw rod 202. Then, the screw 304 is screwed into the screw hole 303 of the inner tapered sleeve 302 and connected with the outer thread of the screw rod 202, so that the counterweight block 301 is tightly combined with the connecting sleeve 204. The connecting effect of the screw 304 further prevents the counterweight block 301 from loosening or displacement during use, ensuring the stability and safety of the dumbbell in different counterweight states. When the counterweight needs to be changed, only the reverse operation is required, screwing out the screw 304, and removing or adding the counterweight block 301. This design makes the adjustment of the counterweight more accurate and reliable, meeting the user's needs for different exercise intensities.

[0035] Specifically, such as Figure 3 As shown, the outer side of the dumbbell handle 1 is provided with an anti-slip cover 4, which is made of rubber material.

[0036] Specifically, such as Figure 3 As shown, the surface of the anti-slip cover 4 has anti-slip properties, and the surface of the anti-slip cover 4 is yellow.

[0037] In this embodiment: the anti-slip cover 4 made of rubber material can provide a soft and comfortable grip, making the user's hands more comfortable during exercise and reducing the discomfort caused by holding the dumbbells for a long time. At the same time, the anti-slip performance can effectively prevent the hands from slipping when sweating or exerting force, greatly reducing the risk of injury due to the dumbbells slipping, and improving the safety of exercise.

[0038] Specifically, such as Figure 3 As shown, the outer side of the inner sleeve rod 201 is fixedly connected with a protrusion 5, and the inner side of the positioning sleeve 203 is a groove, which is engaged with the protrusion 5.

[0039] Specifically, such as Figure 5 As shown, the outer side of the connecting sleeve 204 is conical, and the interior of the connecting sleeve 204 is provided with threads.

[0040] In this embodiment: the clip-on design of the protrusion 5 and the groove allows the positioning sleeve 203 to be quickly and accurately installed on the inner sleeve rod 201 without the need for complicated alignment operations, thereby improving the efficiency of assembly. During the adjustment of the counterweight, this clip-on method can ensure that the relative position of the positioning sleeve 203 and the inner sleeve rod 201 is stable, making subsequent operations convenient. The outer side of the conical connecting sleeve 204 can guide the counterweight block 301 to be smoothly inserted, making the installation process smoother. The internal thread can cooperate with the corresponding structure on the inner side of the counterweight block 301 to enhance the tightness of the connection and prevent the counterweight block 301 from loosening or falling off during use.

[0041] Working principle: During the use of the bamboo dumbbell with optional counterweight, the position and length of the inner sleeve rod 201 in the dumbbell grip 1 can be adjusted by plugging the inner sleeve rod 201 into the dumbbell grip 1 and threading the inner and outer sides of the inner sleeve rod 201 with the screw rod 202, so as to adapt to counterweights 301 of different numbers and weights. The positioning sleeve 203 fixes the counterweight 301 by plugging into the inner sleeve rod 201 and cooperating with the outer connecting sleeve 204 and the counterweight 301. The inner conical sleeve 302 on the inner side of the counterweight 301 is preliminarily positioned with the connecting sleeve 204 through the outer thread, and is screwed in place through the inner screw hole 303 with the screw 304 and the screw rod 202. The groove connection further enhances the connection stability. At the same time, the engagement between the protrusion 5 on the outside of the inner sleeve rod 201 and the groove on the inner side of the positioning sleeve 203 ensures the accurate installation and connection firmness of the positioning sleeve 203. The tapered shape on the outside of the connecting sleeve 204 facilitates the installation of the counterweight 301. The internal thread enhances the tightness of the connection with the counterweight 301. The anti-slip sleeve 4 on the outside of the dumbbell grip 1 is made of rubber material and has a yellow surface with anti-slip properties. It provides a comfortable grip during use and prevents the hands from slipping, thereby improving the safety and convenience of use. In this way, the user can flexibly adjust the counterweight of the bamboo dumbbell according to their own needs to meet different exercise intensity requirements.

[0042] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
