[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 The diagram shows a multi-functional adjustable dumbbell, including a main grip tube 1, an auxiliary grip tube 2, and weight plates 3. There are two auxiliary grip tubes 2 arranged in a triangle with the main grip tube 1. Adjustment rods 101 are slidably mounted on both ends of the main grip tube 1. Threaded rods 201 are threaded to both ends of the auxiliary grip tubes 2. A rotating plate 202 is fixedly connected to the other end of each threaded rod 201. Several weight plates 3 are arranged in a rounded triangle shape. A circular cavity 301 is formed at the center of each weight plate 3. A circular hole 302 matching the adjustment rod 101 is formed at one corner of each weight plate 3, and notches 303 are formed at the other two corners. The other end of the screw rod 201 is inserted into the notch 303. A locking structure 4 for fixing the weight plates 3 is fixedly connected to the other end of the adjustment rod 101 away from the main grip tube 1. Limiting structures 5 are fixedly fitted to both ends of the main grip tube 1 and the auxiliary grip tube 2.

[0022] It is worth noting that the main grip tube 1 and the auxiliary grip tube 2 together form a triangular structure, which allows for multi-functional training operations as follows: One hand can directly grip the main grip tube 1 from the outside to perform bench presses, rows, and overhead presses, achieving training effects similar to traditional dumbbells; Additionally, one hand can also grip the main grip tube 1 between the two auxiliary grip tubes 2 to train wrist strength; finally, by gripping the two auxiliary grip tubes 2 with both hands for up-and-down movement training, arm muscles can be strengthened. This multi-angle grip training method adapts to the training needs of different individuals, enhancing practicality and increasing the fun of training, thus improving training effectiveness. Furthermore, due to the triangular structure formed by the main grip tube 1 and the auxiliary grip tube 2, and the rounded-corner triangle of the weight plate 3, it can be placed stably on the ground, preventing rolling and thus avoiding the potential rolling hazard when placed on a slope.

[0023] Please see Figure 1 and Figure 2 The outer wall of the adjusting rod 101 is fixedly connected with a number of evenly arranged threads 102. The inner wall of the main grip tube 1 is provided with matching threads and an elongated groove that matches the threads 102. The extension adjustment of the adjusting rod 101 is adjusted to fit the thickness of the counterweight 3. By rotating the adjusting rod 101, the threads 102 are rotated to the position of the elongated groove. The adjusting rod 101 is moved horizontally along the main grip tube 1. After the adjusting rod 101 is at the appropriate length, the adjusting rod 101 is rotated again, and the threads 102 are pressed into the threaded position to match, thereby completing the fixation. The threaded rod 201 can be directly rotated in and out to adjust the length. The extension length operation is simple and convenient.

[0024] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The locking structure 4 includes a positioning pin 401 and a rotating ring 403. The counterweight 3 has a positioning groove 402 on one side of the circular hole 302, and a positioning pin 401 is fixedly connected to the other side. The rotating ring 403 is installed on the end of the adjusting rod 101 away from the main grip tube 1. The outer wall of the rotating ring 403 has an I-shaped groove 406. The rotating ring 403 has an insertion hole 4018 on the side wall near the adjusting rod 101. The insertion hole 4018 communicates with the I-shaped groove 406. The insertion hole 4018 has a slidingly connected pin 404 inside. One end of the pin 404 is connected to the inner side wall of the I-shaped groove 406 through a compression spring 407. The outer wall of the pin 404 is threadedly connected to a lever 405. The lever 405 is set perpendicular to the pin 404.

[0025] It is worth noting that when installing the required number of counterweights 3, the positioning pins 401 on two adjacent counterweights 3 are inserted into the positioning slots 402 to achieve quick positioning and stacking of the counterweights 3. Then, the round holes 302 on the counterweights 3 are fitted onto the adjusting rods 101, and the adjusting rods 101 are adjusted to set the required thickness of the counterweights 3 stacking. By pulling the lever 405, the lever 405 moves horizontally in the I-shaped slot 406, allowing the pin 404 to move in the insertion hole 4018. Finally, the pin 404 is inserted into the positioning slot 402 of the outermost counterweight 3 to fix all the counterweights 3. The whole process is simple and quick to operate.

[0026] See Figure 3 , Figure 4 , Figure 5 and Figure 6 The positioning pin 401 fits into the positioning groove 402, and the pin 404 also matches the positioning groove 402, ensuring that the positioning pin 401 and the pin 404 are properly inserted into the positioning groove 402.

[0027] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The locking structure 4 also includes a rotary switch 408, a limiting ring 409, and a flange 4012. The end of the adjusting rod 101 away from the main grip tube 1 is threadedly connected to the flange 4012. A rotating ring 403 is fixedly sleeved on the outer side of the flange 4012. A limiting ring 409 is fixedly connected to one side of the flange 4012 through a semi-circular block 4020. A special gear 4011 is rotatably connected to the side of the limiting ring 409 through a rotating shaft 4010. The special gear 4011 is located inside the internal gear ring 4019. An internal gear ring 4019 is fixedly sleeved on the inner side wall of the rotating ring 403. A rotary switch 408 is rotatably sleeved inside the internal gear ring 4019. One end of the rotary switch 408 rotates through the inside of the limiting ring 409, and a limiting pin 4016 is fixedly connected to the outer side wall of the through end.

[0028] It is worth noting that by rotating the knob switch 408, the limiting pin 4016 can be rotated to a certain angle. The main function of the limiting pin 4016 is to restrict the movement direction of the shaped gear 4011, ensuring that the shaped gear 4011 can only move in one direction. The shaped gear 4011 and the internal gear ring 4019 are always engaged. By changing the direction of the knob switch 408, the engagement area between the shaped gear 4011 and the internal gear ring 4019 is changed, thereby changing the rotation direction of the internal gear ring 4019, and ensuring that it always moves in one direction. Rotating in one direction, after a certain number of counterweight plates 3 are installed, the adjusting rod 101 is adjusted to a suitable length. By rotating the rotating ring 403, the flange 4012 is screwed into and tightens the counterweight plates 3, ensuring the counterweight plates 3 are firmly fixed. By rotating the knob switch 408, the insertion hole 4018 of the rotating ring 403 is aligned with the positioning groove 402, which restricts the rotation of the rotating ring 403 in the opposite direction, further ensuring the locking firmness, reducing the possibility of the counterweight plates 3 loosening due to the dumbbell falling and colliding with the ground, and ensuring the firmness of the counterweight plates 3 after installation.

[0029] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The outer side of the rotating ring 403 is fitted with an annular cover plate 4014 by bolts 4015. The flange 4012 has an annular groove 4021 on the side near the adjusting rod 101, and a gasket 4013 is provided inside it.

[0030] The function of gasket 4013 is to enhance sealing. Placed within the annular groove 4021, gasket 4013 works in conjunction with components such as flange 4012 and swivel ring 403 to effectively prevent media from entering the connection and causing infection or damage to components, thus improving the sealing performance of the entire structural connection. It also provides support and cushioning; gasket 4013 can withstand certain pressure and torque, supporting the connection between swivel ring 403 and flange 4012. Simultaneously, it can absorb and buffer vibration and impact to a certain extent, protecting the connection from damage.

[0031] The outer side of the rotary switch 408 is provided with two symmetrically arranged arrow marks 4017, which can facilitate trainees to quickly rotate the rotary switch 408 in the direction indicated by the arrow marks 4017.

[0032] See Figure 1 and Figure 2 The limiting structure 5 includes a collar 501. Both ends of the main grip tube 1 and the auxiliary grip tube 2 are fixedly fitted with collars 501. Several top bolts 502 are threadedly connected to the side of the collar 501 near the counterweight plate 3. The collar 501 and the top bolts 502 limit the movement of the counterweight plate 3, ensuring that the counterweight plate 3 does not move in the direction of the main grip tube 1 and the auxiliary grip tube 2.

[0033] Working principle: When installing the required number of weight plates 3, insert the positioning pins 401 on two adjacent weight plates 3 into the positioning slots 402 to achieve quick positioning and stacking of the weight plates 3. Then, fit the round holes 302 on the weight plates 3 onto the adjusting rod 101 and adjust the adjusting rod 101 to set the required thickness of the stacked weight plates 3. By pulling the lever 405, the lever 405 moves horizontally in the I-shaped slot 406, allowing the pin 404 to move in the insertion hole 4018. Finally, insert the pin 404 into the positioning slot 402 of the outermost weight plate 3 to fix all the weight plates 3. Its multi-functional training operation is as follows: One hand can directly grasp the main grip tube 1 from the outside to perform bench press, rowing, and overhead press movements, achieving a training effect similar to traditional dumbbells; In addition, one hand can also grasp the main grip tube 1 between the two auxiliary grip tubes 2 to perform wrist strength training; Finally, by grasping the two auxiliary grip tubes 2 with both hands to perform up and down movement training, arm muscles can be exercised.
