[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0031] Referring to Figure 1 、 Figure 2 and Figure 3 , an embodiment provided by the present utility model: a split-type self-adjusting high-pulley back trainer, including a hollow frame 1, a first steel wire rope 15, a second steel wire rope 16 and a third steel wire rope 17. The lower middle part on the right side of the hollow frame 1 is fixedly connected with a base 3. The front side of the top of the base 3 is fixedly connected with a support frame 4. The middle part on the right side of the hollow frame 1 is fixedly connected with a fixed frame 5. The top of the fixed frame 5 is fixedly connected with a connecting frame 6. The top of the connecting frame 6 is rotatably connected with a rotating rod 7. Power arms 8 are arranged on both the left and right sides of the rotating rod 7. The front side of the bottom of the power arm 8 is rotatably connected with a first fixed pulley 9. The top of the support frame 4 is fixedly connected with a T-shaped frame 11 at the rear side. Second fixed pulleys 12 are rotatably connected to both the left and right sides of the T-shaped frame 11. A movable pulley block 13 is arranged at the lower middle part on the front side of the base 3. Multiple first fixed pulleys 9 and second fixed pulleys 12 are respectively in transmission connection with the movable pulley block 13 through the first steel wire rope 15 and the second steel wire rope 16. The lower middle part on the right side of the hollow frame 1 is rotatably connected with a third fixed pulley 14. A third steel wire rope 17 is wound around the outside of the third fixed pulley 14. One end of the third steel wire rope 17 is fixedly connected with a counterweight 18. The ends of the first steel wire rope 15 and the second steel wire rope 16 are respectively connected to the third steel wire rope 17 through the third fixed pulley 14. A connecting arm 10 is fixedly connected to the bottom of the power arm 8. An adjusting mechanism 2 is arranged on the outside of the rotating rod 7. The adjusting mechanism 2 is used to facilitate the use of the device by people of different body types. The other ends of the first steel wire rope 15 and the second steel wire rope 16 are respectively fixedly connected to the corresponding connecting arms 10;

[0032] Specifically, the user first sits on the cushion 25, then lifts both feet and places them on the kicking sponge bar 24 below, and then the user's hands will hold the two power arms 8 at the same time. The two power arms 8 are the key parts of the equipment. They are connected to the first fixed pulley 9 and the second fixed pulley 12, as well as the middle movable pulley set 13. When the user pulls the power arm 8 hard, the first steel wire rope 15 and the second steel wire rope 16 inside the first fixed pulley 9 will start to rotate. This rotation not only drives the rotation of the movable pulley group 13, but also activates the third steel wire rope 17 in the third fixed pulley 14. As the third steel wire rope 17 is wound, the counterweight 18 begins to rise. When the counterweight 18 reaches the highest point, the user can release the power arm 8. At this time, the counterweight 18 will begin to decline due to its own weight. This descending action will restore the power arm 8 to its initial position, completing a complete cycle. This process can be repeated continuously to achieve the purpose of exercise. When the user needs to perform split-motion training, since the first steel wire rope 15 and the second steel wire rope 16 are both connected to the movable pulley group 13, pulling any power arm 8 will cause the counterweight 18 to rise accordingly. At this time, the user can choose different power arms 8 for training according to his or her needs, thereby making the training items more diverse and improving the training effect.

[0033] Reference Figure 3 and Figure 4 The adjustment mechanism 2 includes a fixed rod 201, two fixed rods 201 are respectively fixedly connected to the left and right sides of the rotating rod 7, the outer side of the fixed rod 201 is rotatably connected to a U-shaped frame 202, the outer wall of the fixed rod 201 is provided with a torsion spring 203, one end of the two torsion springs 203 is respectively fixedly connected to one side of the inside of the corresponding U-shaped frame 202, and one side of the two U-shaped frames 202 is respectively fixedly connected to one end of the corresponding power arm 8;

[0034] Specifically, the user bends the power arm 8 to both sides, and the U-shaped frame 202 will also rotate to both sides. Through such operation, the width between the two power arms 8 can be freely adjusted. This width adjustment function enables the device to make corresponding changes according to the training trajectory of the human body to achieve better training effects. When the power arm 8 is released during operation, the torsion spring 203 will be released, and the squeezed force stored in it will be quickly released, thereby driving the power arm 8 to rebound and restore it to its original state, thereby providing users with a more scientific and effective training experience.

[0035] Reference Figure 1 , Figure 2 and Figure 3, a hollow plate 20 is fixedly connected to the front side of the top of the base 3. An activity plate 21 is slidably connected inside the hollow plate 20. A U-shaped plate 23 is fixedly connected to the top of the activity plate 21. Kicking sponge rods 24 are rotatably connected to both the left and right sides of the U-shaped plate 23. An adjustment button 22 is rotatably connected to the left side of the hollow plate 20. The right end of the adjustment button 22 sequentially penetrates through the hollow plate 20 and the activity plate 21. A seat cushion 25 is fixedly connected to the middle and lower part of the front side of the support frame 4. An opening groove 19 is formed in the middle of the right side of the hollow frame 1;

[0036] Specifically, by rotating the adjustment button 22, the limit on the activity plate 21 can be released. At this time, the position of the kicking sponge rod 24 can be adjusted according to the height of the user, thereby improving the practicability of the device.

[0037] Refer to Figure 3 , hollow columns 27 are fixedly connected to both the left and right sides of the top of the support frame 4. The first steel wire rope 15 and the second steel wire rope 16 respectively penetrate through the corresponding hollow columns 27;

[0038] Specifically, through the hollow columns 27, the movement trajectories of the first steel wire rope 15 and the second steel wire rope 16 can be limited, making their movement smoother.

[0039] Refer to Figure 1 and Figure 3 , armrests 26 are fixedly connected to the front ends of the adjacent sides of the two power arms 8. Multiple armrests 26 are all made of rubber material;

[0040] Specifically, through the armrests 26, it is convenient for the staff to hold the power arms 8. And the armrests 26 are all made of rubber material, which can increase the friction between the user's palm and the armrests 26, thus making it more convenient for the user to train.

[0041] Working principle: When using the device, the user first sits on the seat cushion 25, then places the legs under the kicking sponge rods 24, and then simultaneously pulls the two power arms 8 with both hands. The first steel wire rope 15 and the second steel wire rope 16 inside the first fixed pulley 9 will rotate accordingly, thereby driving the pulley block 13 to rotate. At this time, the third steel wire rope 17 inside the third fixed pulley 14 will be wound up to drive the counterweight 18 to rise. Then release the power arm 8, and the counterweight 18 will descend due to its own weight, driving the power arm 8 to return to its original state. Repeating this cycle can carry out exercises. When split training is required, since both the first steel wire rope 15 and the second steel wire rope 16 are connected to the movable pulley block 13, pulling any one of the power arms 8 will cause the counterweight 18 to rise. There are various training items, thus improving the training effect;

[0042] When the user is training, the power arm 8 is bent to both sides, and the U-shaped frame 202 will rotate to both sides accordingly, so that the width between the two power arms 8 can be adjusted, so that the device can be changed according to the training trajectory of the human body. When the power arm 8 is released, the torsion spring 203 will release the squeezed force and drive the power arm 8 to rebound to its original state, thereby improving the practicality of the device.

[0043] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
