The guide ring 370 may be a ceramic ring with a smooth inner wall, so as to reduce contact friction with the first pull rope 230 and the second pull rope 320, and simultaneously, can perform good guiding and limiting effects.

Because some patients do not have sufficient mobility to facilitate the movement of their legs, the leg pressure or pressure applied to or removed from the footrest assembly 310 may be too fast, resulting in too fast movement of the first and second pull cords 230 and 320, which may cause accidental arm injuries.

Referring to fig. 3, 7 and 8, the auxiliary arm-raising training device for rehabilitation of arm of geriatric department further includes a rope-moving prevention mechanism 40, two groups of rope-moving prevention mechanisms 40 are respectively disposed outside the first rope 230 below the supporting cross arm 210 and outside the second rope 320 below the second pulley 330, and the rope-moving prevention mechanism 40 includes a bobbin 410, a U-shaped clamp plate 420, an adjusting bolt 430, a bottom cover 440, a top cover 450, an elastic washer 460 and a pressure spring 470. The bottom cover 440 and the top cover 450 are respectively fixedly arranged at the bottom end and the top end of the bobbin 410, and the bottom cover 440 and the top cover 450 are respectively fixed with the bobbin 410 by bolts; the U-shaped clamp plate 420 is arranged inside the bobbin 410, a notch is formed in the side wall of the bobbin 410, the U-shaped clamp plate 420 can transversely penetrate through the notch in a sliding mode, a screw of the adjusting bolt 430 is in threaded connection with the side wall of the bobbin 410, and the inner thread matched with the adjusting bolt 430 is formed in the side wall of the bobbin 410; the end of the screw rod of the adjusting bolt 430 is rotatably connected to the outer wall of the U-shaped clamp plate 420, the elastic gasket 460 is arranged above the top cover 450, and the elastic gasket 460 can be a rubber gasket; and both ends of the pressure spring 470 are respectively connected to the top cover 450 and the elastic washer 460, and the first pulling rope 230 and the second pulling rope 320 respectively and movably penetrate through the elastic washer 460, the pressure spring 470, the top cover 450, the bobbin 410 and the bottom cover 440 in sequence.

The adjusting bolt 430 is rotated to move the U-shaped clamp plate 420 through the notch on the outer wall of the bobbin 410, so that the first pulling rope 230 and the second pulling rope 320 of the U-shaped clamp plate 420, which respectively pass through, are clamped by the U-shaped clamp plate 420 and the bobbin 410, and the pulling rope movement prevention mechanism 40 is fixed outside the first pulling rope 230 and the second pulling rope 320, respectively. When the pressure applied to the pedal assembly 310 by the leg of the patient is too fast, the elastic gasket 460 in the pull rope moving protection mechanism 40 outside the first pull rope 230 contacts with the bottom of the supporting cross arm 210, the elastic gasket 460 and the pressure spring 470 have good and constant-force-unloading buffering effect, the protective arc-shaped supporting plate 220 drives the arm to quickly rise and then has certain buffering effect, the arm on the arc-shaped supporting plate 220 is effectively protected, and the arm is prevented from being accidentally injured. When the pressure on the pedal assembly 310 is too fast when the leg of the patient is unloaded, the elastic pad 460 in the pull rope movement protection mechanism 40 outside the second pull rope 320 is in contact with the bottom of the second pulley 330, the elastic pad 460 and the pressure spring 470 have good and constant unloading force buffering effect, the arc-shaped supporting plate 220 is protected to drive the arm to descend quickly, then certain buffering effect is achieved, the arm on the arc-shaped supporting plate 220 is effectively protected, and the arm is prevented from being accidentally injured. The rotation of the adjusting bolt 430 to drive the U-shaped clamp plate 420 to clamp the pull rope not only has the function of fixing the pull rope movement prevention mechanism 40, but also can adjust the relative height of the pull rope movement prevention mechanism 40 on the first pull rope 230 and the second pull rope 320. That is, when the pull rope moving protection mechanism 40 is adjusted to different positions on the first pull rope 230 and the second pull rope 320, the lifting height of the arc-shaped supporting plate 220 can be changed, that is, the arm rehabilitation lifting height can be adjusted according to the requirements of different patients, so that a better rehabilitation training effect is achieved.
