[0016] 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.

[0017] Please see Figures 1-3 It is understood that this utility model provides a technical solution: a fitness equipment with adjustable support height, including a base 1, a support block 2, a connecting rod 3, a support plate 4, a sponge pad 5, and a rubber roller 6. The support block 2 is welded to one end of the surface of the base 1. The connecting rod 3 for supporting and rotating the support plate 4 is connected to the inner side of the top of the support block 2. The sponge pad 5 for supporting the fitness user is installed on the top of the support plate 4. The rubber roller 6 for limiting the legs of the fitness user is installed on the outer side of one end of the support plate 4. The connecting plate 7 for guiding the moving plate 10 is welded to the surface of the base 1 away from the support block 2. The servo motor 8 for driving the threaded rod 9 to rotate is installed on the surface of the base 1 near the connecting plate 7. The servo motor 8 can drive the threaded rod 9 to rotate in both forward and reverse directions. The moving plate 10 and the threaded rod 9 form a threaded structure, and the moving plate 10 and the connecting plate 7 form a sliding structure. The fixing rod 11 for supporting the rotating plate 14 is connected to the inner side of the moving plate 10.

[0018] exist Figures 1-3 In the middle: the rotating plate 14 and the fixed rod 11 form a rotating structure, and the rotating plate 14 can support the support plate 4.

[0019] exist Figure 1 and Figure 2 In the middle: two sets of fixing blocks 12 for fixing the connecting shaft 13 are welded to the bottom of the support plate 4, and the connecting shaft 13 and the two sets of fixing blocks 12 are welded together. The rotating plate 14 and the connecting shaft 13 form a rotating structure.

[0020] In practice, sit-up fitness equipment is a common type of fitness device. Traditional sit-up fitness equipment requires adjusting the height of the support plate 4 before use. This traditional method of adjusting the height of the support plate 4 is inconvenient. A servo motor 8 can be activated. When the servo motor 8 rotates forward, it drives the threaded rod 9 to rotate forward. When the threaded rod 9 rotates forward, it drives the moving plate 10 to slide threadedly away from the base 1. As the moving plate 10 moves, it slides through the connecting plate 7, and the movement of the moving plate 10 also drives the fixed rod 11 to move. When moving, the rotating plate 14 can be moved upward. When the rotating plate 14 moves, it can push the connecting shaft 13. When the connecting shaft 13 moves, it can move the fixed block 12 and the support plate 4. At the same time, when the rotating plate 14 moves, it can rotate through the connecting shaft 13 and the fixed rod 11. When the support plate 4 moves, it can rotate through the connecting rod 3, so that the tilting height of the support plate 4 can be adjusted. When the support plate 4 rotates to the designated position, the servo motor 8 can be turned off. At this time, the tilting height of the support plate 4 can be adjusted according to the actual situation of the user.

[0021] See Figures 1-3 It can be seen that by adjusting the angle of the support plate 4, the upward support height of the support plate 4 can be adjusted accordingly, so that it is not necessary for personnel to manually pull the support plate 4 for adjustment, making the upward support height adjustment method of the support plate 4 simple and convenient.

[0022] exist Figure 1 , Figure 4 and Figure 5 In the middle: The bottom of the support plate 4 is welded with a vertical plate 15 for connecting the connecting seat 16. The connecting seat 16 is slidably connected to a slider 17. The top of the slider 17 is connected to a threaded post 18. The outside of the threaded post 18 is threadedly connected to a threaded cylinder 19 for fixing the position of the slider 17. The inner side of the end of the slider 17 is connected to a rotating shaft 20.

[0023] exist Figure 1 , Figure 4 and Figure 5 In the middle: A rotating block 21 for supporting the extension pad 22 is rotatably connected to the outside of the rotating shaft 20. The rotating block 21 can be rotated by the rotating shaft 20, and the extension pad 22 can extend the supporting area of ​​the sponge pad 5, thereby preventing people with wider body size from falling. A threaded knob 23 is threadedly connected to the bottom of the slider 17 near the rotating block 21. A limiting post 24 for limiting the rotation block 21 is welded to the end of the threaded knob 23. A through hole matching the size of the limiting post 24 is opened through the interior of the rotating block 21.

[0024] In practice, when using the sit-up fitness equipment, the user's back rests on the sponge mat 5. Because the sponge mat 5 is relatively narrow, wider individuals may fall off, making it difficult for the mat to provide adequate support. First, loosen the threaded knob 23 to allow the limiting post 24 to slide out of the through hole inside the rotating block 21. At this point, the limiting post 24 no longer limits the rotating block 21. Then, loosen the threaded cylinder 19 so that its bottom no longer presses against the top of the connecting seat 16, allowing the slider 17 to be pulled away from the vertical plate 15. When the slider 17 slides to its maximum distance, it can... Tighten the threaded cylinder 19 so that the bottom of the threaded cylinder 19 can be pressed and fixed to the top of the connecting seat 16, so that the position of the slider 17 is not easy to loosen. Then pull the extension pad 22 towards the sponge pad 5. When the extension pad 22 moves, it can drive the rotating block 21 to rotate through the rotating shaft 20. When one side of the extension pad 22 rotates to the surface of the sponge pad 5, the limiting post 24 can be inserted into the slider 17 and the threaded knob 23 is tightened so that the limiting post 24 can rotate to the outer surface of the rotating block 21. At this time, the limiting post 24 can limit the rotating block 21, so that the rotating block 21 and the extension pad 22 are not easy to loosen.

[0025] See Figure 1 , Figure 4 and Figure 5 It can be seen that when the two sets of extension pads 22 are fixed on both sides of the sponge pad 5, the two sets of extension pads 22 can increase the support area of ​​the sponge pad 5 for the back of the person, so that when a person with a wider body lies on the sponge pad 5, it is not easy to fall off, thereby improving the stability of the sponge pad 5 in supporting the back of the person.
