[0042] When doing fitness, the feet of a person are limited by the limiting mechanism 4, so that when doing sit-ups, the person does not need to repeatedly adjust their posture, and the force application points are the same each time, which is not easy to affect the fitness effect.

[0043] Specifically, the limiting mechanism 4 includes a connecting frame 41, a rotating rod 42, an extension rod 43, a limiting column 44 and a fixing assembly 45; the connecting frame 41 is fixedly connected to the seat plate 2; the rotating rod 42 is rotatably connected to the connecting frame 41, and the rotating axis 31 of the rotating rod 42 is horizontal and perpendicular to the length direction of the support frame 1; one end of the extension rod 43 is connected to the rotating rod 42, and the length direction of the extension rod 43 is perpendicular to the axis of the rotating rod 42; two limiting columns 44 are provided, and the two limiting columns 44 are respectively located on both sides of the extension rod 43 and the limiting columns 44 are arranged at one end of the extension rod 43 away from the rotating rod 42, the two limiting columns 44 are coaxially arranged and the axis of the limiting column 44 is parallel to the axis of the rotating rod 42; the fixing assembly 45 is used to fix the rotating rod 42 on the connecting frame 41.

[0044] When doing sit-ups, the two feet are hooked on the two limit posts 44 respectively, so as to limit the feet; however, fitness personnel with different heights and sit-ups in different postures after adjusting the backboard 3 need to limit the feet at different positions, and by rotating the rotating rod 42, the extension rod 43 and the limit post 44 can be driven to rotate around the axis of the rotating rod 42, so as to adjust the position of the limit post 44 around the axis of the rotating rod 42, so as to adjust the position of the limit post 44 according to the height of the fitness personnel and the different sit-up postures.

[0045] Specifically, the connecting frame 41 includes two connecting plates 411 , and the two connecting plates 411 are respectively located at two ends of the rotating rod 42 ; two fixing components 45 are provided, and the two fixing components 45 are respectively arranged on the two connecting plates 411 .

[0046] Specifically, the fixing assembly 45 includes a connecting column 451, a sliding sleeve 452, meshing teeth 4521, a fixing sleeve 453 and an elastic member 454. The connecting column 451 passes through the connecting plate 411 and is threadedly connected to the end of the rotating rod 42. The connecting column 451 and the rotating rod 42 are coaxially arranged. The sliding sleeve 452 is sleeved outside the connecting column 451 and is located on the side of the connecting plate 411 away from the rotating rod 42. The sliding sleeve 452 can slide outside the rotating rod 42 along the axis direction of the rotating rod 42. A plurality of meshing teeth 4521 evenly arranged around the sliding sleeve 452 are fixedly connected outside the sliding sleeve 452. The fixed sleeve 453 is fixedly connected to the side of the connecting plate 411 away from the rotating rod 42. The fixed sleeve 453 is sleeved outside the connecting column 451 and is coaxially arranged with the connecting column 451. A plurality of meshing grooves 4531 evenly arranged around the axis of the fixed sleeve 453 are arranged in the fixed sleeve 453.

The elastic member 454 is used to apply an elastic force toward the connecting plate 411 to the sliding sleeve 452.

[0047] When the rotating rod 42 needs to be rotated, the sliding sleeve 452 is pulled to slide away from the connecting plate 411, so that the engaging teeth 4521 are disengaged from the engaging grooves 4531. Then, the rotating rod 42 is rotated. When the rotating rod 42 is rotated to a predetermined angle, the limit on the sliding sleeve 452 is released. Under the action of the elastic member 454, the sliding sleeve 452 slides towards the connecting plate 411 until the plurality of engaging teeth 4521 on the sliding sleeve 452 are respectively embedded into the plurality of engaging grooves 4531. Through the limitation of the engaging teeth 4521 and the engaging grooves 4531, the position of the rotating rod 42 is fixed, so that the rotating rod 42 is fixed on the connecting plate 411.

[0048] Specifically, a limiting groove 4511 is formed on the outer side of the connecting column 451 along the axial direction of the connecting column 451, and the limiting groove 4511 penetrates the connecting column 451 towards the rotating rod 42; a limiting block 4522 is fixedly connected inside the sliding sleeve 452, and the limiting block 4522 is embedded into the limiting groove 4511 and can slide along the length direction of the limiting groove 4511 in the limiting groove 4511. Through the arrangement of the limiting block 4522 and the limiting groove 4511, the sliding sleeve 452 will not rotate outside the rotating rod 42, so that when the engaging teeth 4521 are embedded into the engaging grooves 4531, it can be ensured that the rotating rod 42 will not rotate relative to the connecting plate 411.

[0049] Specifically, a clamping groove 4512 is arranged on one side of the limiting groove 4511, and the clamping groove 4512 is located at one end of the limiting groove 4511 away from the rotating rod 42. When the limiting block 4522 is aligned with the clamping groove 4512, the limiting block 4522 can be embedded into the clamping groove 4512 through the rotation of the sliding sleeve 452 around the axis of the connecting column 451; when the limiting block 4522 is embedded into the clamping groove 4512, the engaging teeth 4521 are disengaged from the engaging grooves 4531.

[0050] Through the arrangement of the clamping groove 4512, after the engaging teeth 4521 are disengaged from the engaging grooves 4531, the limiting block 4522 can be clamped into the clamping groove 4512. At this time, it is not necessary for the operator to limit the sliding sleeve 452 by hand, and only the rotating rod 42 needs to be rotated, so that the rotation operation of the rotating rod 42 is more convenient.

[0051] Specifically, the elastic member 454 is set as a spring, and the spring is sleeved outside the connecting column 451. A limiting ring 455 is fixedly connected to the outer side of the end of the connecting column 451 away from the rotating rod 42; the spring is arranged between the sliding sleeve 452 and the limiting ring 455, and the two ends of the spring are respectively abutted against the sliding sleeve 452 and the limiting ring 455.

[0052] Specifically, two rollers 12 are provided at a position near the bottom of one end of the support frame 1 away from the seat board 2; a connection frame 46 is provided between the rotating rod 42 and the extension rod 43; the connection frame 46 includes side plates 461 and a cross plate 462. There are two side plates 461, and the two side plates 461 are respectively fixedly connected to positions near both ends of the rotating rod 42. The length direction of the side plate 461 is parallel to the length direction of the extension rod 43; both ends of the cross plate 462 are respectively fixedly connected to the ends of the two side plates 461 away from the rotating rod 42, and the extension rod 43 is fixedly connected to the cross plate 462. Through the arrangement of the connection frame 46, a person can hold the rotating rod 42 to pull the fitness bench to tilt so that the two rollers 12 are in contact with the ground, and then hold the rotating rod 42 to pull the fitness bench to move.

[0053] Specifically, a rotating shaft 31 is rotatably connected to the back board 3, and two support rods 32 are fixedly connected to the rotating shaft 31. One ends of the two support rods 32 away from the back board 3 are fixedly connected to an adjusting shaft 33; a plurality of adjusting grooves 11 with different heights are provided on the support frame 1, and the angle of the back board 3 is adjusted by adjusting the adjusting shaft 33 in different adjusting grooves 11.
