When using, at first adjust the height and the position of cushion main part 25 through cushion mechanism 2 according to patient's size, then patient trains the low limbs through stepping on the pedal, trains the upper limbs through handle 520 pulling montant 519, wherein resumes partly back when patient's limbs motion ability, can adjust pedal mechanism 3 and arm training mechanism 5's resistance size simultaneously through resistance adjustment mechanism 4, is convenient for promote training efficiency.

The height of the cushion main body 25 of the cushion mechanism 2 is adjusted through the telescopic column 24, and at the same time, the telescopic column 24 can be pushed, so that the telescopic column 24 drives the limit slide plate 23 to slide in the second slide groove 22, the positions of the cushion main body 25 and the pedal mechanism 3 are adjusted, a comfortable angle is convenient to find, after a patient trains for a period of time, the limb recovers to a certain degree, the training resistance needs to be increased, the rotating wheel 44 is rotated, the rotating wheel 44 drives the long rod 43 to rotate, the long rod 43 drives the support plate 411 to move upwards through the external thread 48 on the surface of the long rod 43, the support plate 411 pushes the nearest counterweight 46 to move upwards in the process of moving upwards, the counterweight 46 is supported through the stepped side wall of the stepped inner groove 45, when the support plate 411 moves upwards gradually, the counterweight 46 is supported one by one another, the weight of the supported counterweight 46 falls on the support plate 411, the support plate 411 presses the, the trapezoidal pressing block 413 at the bottom end of the long rod 43 distributes the weight to the inclined insertion blocks 34 at two sides through the inclined surface, so that the inclined insertion blocks 34 generate a large transverse thrust, the friction grains 35 on the surface of the inclined insertion blocks 34 are in contact with the circular rotating plate 37, the larger the positive pressure of the inclined insertion blocks 34 on the circular rotating plate 37 is, the larger the sliding friction force is, the larger the resistance is when the circular rotating plate 37 rotates, and the larger the rotation resistance of the circular rotating plate 37 is, so that the rotation resistance of the pedal main body 310 is increased.

When the long rod 43 rotates, the second helical gear 57 is driven to rotate at the same time, the second helical gear 57 drives the first helical gear 56 to rotate, the first helical gear 56 drives the short rod 55 to rotate, the short rod 55 drives the cylindrical block 59 to rotate through the limiting block 512, the cylindrical block 59 drives the torsion spring 515 to apply force to the torsion spring, so that the vertical rod 519 needs larger torsion force when rotating, wherein the cylindrical block 59 can slide in the first circular groove 58, the torsion spring 515 is convenient to compensate for contraction when rotating, and the stop lever 521 plays a limiting role in rotation of the vertical rod 519.

The invention has the beneficial effects that:

(1) according to the multifunctional patient rehabilitation device, the resistance adjusting mechanism is arranged, so that the training resistance can be increased when limbs of a patient are rehabilitated to a certain degree after the patient trains for a period of time, the patient can be rehabilitated earlier conveniently, the resistance of the pedal mechanism and the resistance of the arm training mechanism can be increased simultaneously by the resistance adjusting mechanism, and the adjusting process is very convenient.

(2) According to the multifunctional patient rehabilitation device, the balancing weight is arranged in the resistance adjusting mechanism, the friction force generated by rotation of the pedals is increased step by step in a step-by-step counterweight accumulation mode, the increased friction force is relatively stable and has hierarchy, the training effect is better, the torsion force generated when the vertical rods rotate is increased by arranging the torsion springs in the arm training mechanism, the adjusting process is smoother, and the upper limb strength training is facilitated.

(3) According to the multifunctional patient rehabilitation device, the height of the cushion main body of the cushion mechanism is adjusted through the telescopic column, and meanwhile the telescopic column can be pushed, so that the telescopic column drives the limiting sliding plate to slide in the second sliding groove, the positions of the cushion main body and the pedal mechanism are adjusted, and a comfortable angle is convenient to find.
