DETAILED DESCRIPTION
[0024] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementations:
[0025] like Figure 1-Figure 4 As shown, a stepper is provided with a limited anti-detachment unit 3 on the frame 1, and the limited anti-detachment unit 3 includes a positioning member 39 fixed on the frame, a limiting screw group 38 threadedly connected to the positioning member 39, a limiting member 31 assembled on the limiting screw group 38, a pulley 33 rotatably connected to the limiting member 31, and a steel wire rope 36 wound around the pulley 33, and the limiting member 31 includes one or more limiting columns 32 for limiting the steel wire rope 36.
[0026] In this embodiment, one side of the limiting member 31 is configured to be fan-shaped, and longitudinally arranged limiting columns 32 are provided at both ends of the left and right sides, and a first extension portion 10 extending from the surface, the first extension portion 10 is provided with a first mounting hole 6, and one side of the limiting member 31 is configured to be an extended second extension portion 11, and the second extension portion 11 is provided with a second mounting hole 7.
[0027] Furthermore, the spacing between the second mounting hole 7 and the first mounting hole 6 forms a mounting space, and the pulley 33 is placed in the mounting space.
[0028] Specifically, the pulley 33 includes a pulley hole 35 and a wheel groove 34 . The pulley hole 35 is aligned with the center of the first mounting hole 6 and the second mounting hole 7 and is fixed by a screw group 40 , wherein the wheel groove 34 is used to place the wire rope 36 .
[0029] Furthermore, the limiting posts 32 pointing vertically downward at both ends of the limiting member 31 can position the steel wire rope 36 in the wheel groove 34 to prevent the steel wire rope 36 from falling off during use.
[0030] In this embodiment, the positioning member 39 is provided with a fourth mounting hole 9 for matching with the limiting screw assembly 38 , wherein the diameter of the fourth mounting hole 9 of the positioning member 39 is equal to the diameter of the third mounting hole 8 of the limiting member 31 .
[0031] Furthermore, the limiting screw group 38 can completely pass through the fourth mounting hole 9 and the third mounting hole 8, wherein the nut at the tail end of the limiting screw group 38 contacts the wire rope 36, further preventing the wire rope 36 from falling off from the wheel groove 34. The limiting screw group 38 is also provided with a rotatable nut.
[0032] In this example, both ends of the steel wire rope 36 are provided with metal interfaces 37 that can be connected to the frame 1, wherein both ends of the bottom of the frame 1 are provided with plate frame connectors 12 that match the pedal frame, and the left pedal frame 51 and the right pedal frame 52 are fixed by a screw group 40, and the bottom of the left pedal frame 51 and the right pedal frame 52 are provided with connecting components 4 that connect to the metal interfaces 37, and the connecting components 4 are placed at the bottom of the frame 1 by welding. After the metal interfaces 37 at both ends of the steel wire rope 36 are aligned with the center points of the connecting components 4, they are fixed with the screw group 40 to form a complete limit and anti-detachment unit 3.
[0033] In this example, the stepper also includes an electronic meter 2 and a ring 13, wherein the screen of the electronic meter 2 adopts an LED display screen design and records various data of the stepper during use.
[0034] Furthermore, during use, the stepper simulates climbing stairs or mountains through the lever principle, and during this use, it is inevitable that the wire rope 36 may fall off or the pulley 33 may be damaged.
[0035] In summary, the utility model adds a limit anti-slip unit 3 to prevent the wire rope 36 or the pulley 33 from loosening or deformation and damage during use, thereby increasing the service life of the stepper.
