[0028] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1 - Figure 6 This utility model provides a technical solution: an adjustable resistance tension platform, including a base plate 1, an embedded groove 6 on the top of the base plate 1, and an installation plate 7 installed in the embedded groove 6. A rubber pad 2 is connected to the top of the installation plate 7. Tension adjustment devices 8 are connected to both sides of the top of the base plate 1, and a connecting rope 4 is connected to one side of the tension adjustment device 8. A handle 3 is connected to the other end of the connecting rope 4. The tension adjustment device 8 includes an adjustment groove 804. Multiple adjustment blocks 806 are slidably connected to the bottom of the adjustment groove 804. A sliding sleeve is embedded in the adjustment block 806, and a support rod 803 is slidably connected in the sliding sleeve. A first spring 802 is sleeved on the outer wall of the support rod 803. Sliding grooves 805 are opened on both sides of the inner wall of the adjustment groove 804, and sliders 808 are slidably connected in the sliding grooves 805. The same adjustment plate 816 is connected between two sliders 808. A connecting plate 809 is connected to one side of the adjustment plate 816, and multiple support plates 810 are connected to the top of the adjustment plate 816. Each side has a travel groove 811, and a travel block 813 is slidably connected in the travel groove 811. A common pin 814 connects two corresponding travel blocks 813. A pull block 815 is connected to the top of the pin 814. A pin hole 807 is opened at the top of the adjusting block 806, and multiple through holes 812 are opened at the top of the adjusting plate 816. An adjusting groove 804 is opened at the top of the base plate 1, and the two ends of the support rod 803 are respectively connected to the two sides of the inner wall of the adjusting groove 804. The first spring 80... 2. The two ends are respectively connected to one side of the adjusting block 806 and one side of the inner wall of the adjusting groove 804. The end of the connecting rope 4 away from the handle 3 is connected to one side of the connecting plate 809. The bottom of the adjusting plate 816 is attached to the top of the adjusting block 806 and slidably connected. Another sliding sleeve is embedded in the slider 808, and a sliding rod 801 is slidably connected in the other sliding sleeve. The two ends of the sliding rod 801 are respectively connected to the two sides of the inner wall of the groove 805. Two guide rings 5 ​​are connected to the top of the bottom plate 1, and the connecting rope 4 passes through the guide rings 5.

[0030] In a specific implementation, by setting up a tension adjustment device 8, pulling the pull block 815 upward causes the pull block 815 to move the bottom pin 814 upward, thereby causing the bottom of the pin 814 to slide out of the pin hole 807, so that the pin hole 807 loses its lateral fixing effect on the pin 814. Then, by continuously pulling the pull block 815, the pin 814 slides out of the through hole 812. Then, by pushing the pull block 815 to one side, the pull block 815 causes the pin 814 to rotate around the stroke block 813, thereby placing the pin 814 horizontally on the top of the adjustment plate 816. By setting the pin 814 to be placed horizontally, it avoids... When the device is in use, the pin 814 may shake and re-insert into the pin hole 807, affecting its use. By setting an adjustable pin 814 to limit the adjustment block 806, the device can adjust the number of springs for stretching and compression according to the user's needs, thus making the device suitable for different users. By setting a slide bar 801 and a slider 808 to support the adjustment plate 816, the device can be prevented from shifting when the adjustment plate 816 moves, thus avoiding affecting the user's use. By setting a support rod 803 to support the first spring 802, the first spring 802 can be prevented from bending during compression, thus avoiding the generation of resistance.

[0031] Two installation / removal devices 9 are installed at the bottom of the embedded groove 6. The installation / removal device 9 includes a connecting groove 906, which is opened on one side of the base plate 1. The top of the connecting groove 906 has a slot 904, which is opened at the bottom of the embedded groove 6. A snap-fit ​​block 903 is slidably connected in the slot 904. A pressure plate 905 is connected to the bottom of the snap-fit ​​block 903. The outer wall of the pressure plate 905 is slidably connected to the inner wall of the connecting groove 906. Two fixing grooves are opened on one side of the pressure plate 905, and a fixing rod 901 is slidably connected in the fixing groove. The other end of the fixing rod 901 is connected to one side of the inner wall of the connecting groove 906. A second spring 902 is sleeved on the outer wall of the fixing rod 901. The two ends of the second spring 902 are respectively connected to one side of the pressure plate 905 and one side of the inner wall of the connecting groove 906. Two snap-fit ​​grooves are opened at the bottom of the mounting plate 7, and the snap-fit ​​grooves are snapped into the corresponding snap-fit ​​block 903. Both sides of the inner wall of the embedded groove 6 have a buckle groove 10.

[0032] In a specific implementation, by setting up the installation and removal device 9, during installation, pressing down on the rubber pad 2 causes the rubber pad 2 to move the snap-fit ​​groove at the bottom of the mounting plate 7, squeezing the snap-fit ​​block 903. This causes the snap-fit ​​block 903 to move to one side, which in turn causes the snap-fit ​​block 903 to move the pressure plate 905. This causes the pressure plate 905 to squeeze the second spring 902, resulting in a rebound force on the second spring 902. The fixing rod 901 supports the second spring 902 to prevent it from wobbling and affecting the rebound effect. After the mounting plate 7 is installed in place, the snap-fit ​​block 902... 3. The second spring 902 rebounds and engages with the snap-fit ​​groove, thereby fixing the mounting plate 7. When replacing, press the pressure plate 905, causing the pressure plate 905 to move inward, which in turn causes the pressure plate 905 to move the snap-fit ​​block 903 to one side, thereby causing the snap-fit ​​block 903 to disengage from the snap-fit ​​groove, thus causing the snap-fit ​​block 903 to lose its fixing device from the mounting plate 7. Then, the rubber pad 2 can be taken out from the buckle slots 10 on both sides for quick replacement, avoiding cross-infection caused by bacteria on the rubber pad 2 when the user uses it barefoot, which would affect the user's health.

[0033] Working principle: In use, by pulling the pull block 815 upward, the pull block 815 moves the pin 814 upward, causing the pin 814 to slide out of the pin hole 807, so that the pin hole 807 loses its limiting effect on the pin 814. Then, the pin 814 is lifted upward until it slides out of the through hole 812. Then, the pin 814 is rotated and placed on the top of the adjusting plate 816, so that the number of first springs 802 can be adjusted according to the user's strength, thus meeting the needs of different users. After long-term use, by pressing the pressure plate 905, the pressure plate 905 moves the locking block 903, causing the locking block 903 to disengage from the locking groove, so that the locking block 903 loses its fixing device to the mounting plate 7. Then, the rubber pad 2 can be removed through the two side slots 10 for replacement, to prevent the user from using it barefoot, which may cause bacteria to grow on the surface of the rubber pad 2 and affect the health of subsequent users.
