By setting the first threaded rod 5, nut 6, and screw holes 4 in cooperation, it is convenient for the operator to adjust the number of counterweight blocks 3 to adjust the amount of damping force.

[0021] A rope 7 is fixedly connected to the outer surface of the nut 6. A first guide wheel 8 is rotatably connected to the outer surface of the rope 7. A second guide wheel 9 is rotatably connected to the outer surface of the first guide wheel 8 through the rope 7. A rotating rod 10 is fixedly connected inside the second guide wheel 9. A slider 11, which is slidably connected to the support frame 1, is rotatably connected to one end of the rotating rod 10 that passes through the second guide wheel 9. A screw is threaded inside the slider 11, and the outer surface of the screw is threaded to the support frame 1. A spring 12 is fixedly connected to the bottom of the slider 11. A third guide wheel 13 is rotatably connected to one end of the rope 7 that passes through the first guide wheel 8. The third guide wheel 13, the second guide wheel 9, and the first guide wheel 8 are arranged in a triangle for easy adjustment. The length of the rope 7 is specified. One end of the rope 7, guided by the third guide wheel 13, is fixedly connected to a pull plate 14. Above the pull plate 14, there is a limiting block 16 for limiting the pull plate 14. The limiting block 16 is slidably connected to the slide rod 15. The inside of the limiting block 16 is threaded with a second threaded rod 17. The second threaded rod 17 passes through one end surface of the limiting block 16 and is threadedly connected to the slide rod 15. The inside of the slide rod 15 has a threaded hole that matches the size of the second threaded rod 17. By setting the limiting block 16, the second threaded rod 17, the threaded hole, the third guide wheel 13, the second guide wheel 9, and the first guide wheel 8 to work together, the height of the pull rod 19 can be adjusted to suit people of different heights.

The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0024] The implementation principle of the fitness device based on damping force adjustment in this application embodiment is as follows: During use, the number of counterweights 3 is adjusted according to the needs of exercise. Then, the first threaded rod 5 is rotated and inserted into the screw hole 4 through the nut 6. During the adjustment process, when the rope 7 is tightened, the rope 7 drives the second guide wheel 9 to move upward. The second guide wheel 9 drives the slider 11 to stretch the spring 12 through the rotating rod 10. When the rope 7 is loosened, the spring 12 pulls the slider 11 to drive the second guide wheel 9 to move downward through the rotating rod 10 to tighten the rope 7, thereby adjusting the number of counterweights 3 and adjusting the amount of damping force.

[0025] Rotate the second threaded rod 17 to disengage it from the slide rod 15, then push the limiting block 16 to drive the pull plate 14 to drive the hanging block 18 and the pull rod 19 to move downward or upward. At the same time, the pull plate 14 pulls the rope 7 to drive the second guide wheel 9 to move upward or downward. Then rotate the screw to pass through the slider 11 and insert it into the support frame 1 to complete the fixation of the support frame 1, thereby adjusting the height of the pull rod 19 to suit people of different heights.
