The entire structure of the rocker arm torsion mechanism is supported by the horizontal fixed shaft 4, and because the push-pull spring 5 is arranged, when the arm strength needs to be exercised, the torsion assembly can be pulled to the side close to the body according to the body direction of the patient to overcome the elastic force of the push-pull spring 5, so as to achieve the purpose of exercising the arm proportion; and when the force is removed, the elastic force is returned.

[0035] In any of the above solutions, preferably, the torsion assembly comprises a sleeving disc 6 movably sleeved on the outer side wall of the horizontal fixed shaft 4, the right end face of the sleeving disc 6 being fixedly connected with the left end of the push-pull spring 5, a torsion spring 7 being sleeved on the outer side wall of the horizontal fixed shaft 4 on the left side of the sleeving disc 6, the right end of the torsion spring 7 being fixed on the left end face of the sleeving disc 6, a torsion disc 8 being movably sleeved on the outer side wall of the horizontal fixed shaft 4 on the left side of the torsion spring 7, the right end face of the torsion disc 8 being fixedly connected with the left end of the torsion spring 7, and two rotating and twisting grip handles 9 being fixedly arranged on the left end face of the torsion disc 8.

The locking of the sleeving disc 6 is realized by controlling the left-right extension of the horizontal locking screw 10, the unlocking of the sleeving disc 6 is realized by controlling the right-left extension of the horizontal locking screw 10, and when the sleeving disc 6 is unlocked, the entire sleeving disc 6 can swing and rotate within a certain rotation angle range, so the force used by the patient is different when the rotation of the torsion disc 8 is operated and the sleeving disc 6 is locked, so the torsion exercise of different gears can be realized, so as to achieve the purpose of exercising the arm in different degrees.

The displacement mechanism is used to drive the massage chair seat 3 at the end thereof to approach or move away from the swing arm torsion mechanism.

[0043] The safety type adjustable rehabilitation device needs the patient to sit on the massage chair seat 3 of the application first, and then adjust the displacement mechanism by button or remote control to adjust itself to the appropriate position. When adjusting, the patient's arms hold the rocker arm tensioning mechanism to correct the comfort of the current position and make fine adjustments as needed. After the position is adjusted, the patient's hands hold the rocker arm tensioning mechanism to rotate the rocker arm tensioning mechanism through the crossed arms to exercise the arms.

[0044] In any of the above solutions, preferably, the rocker arm tensioning mechanism includes a horizontal fixed shaft 4 fixedly installed on the upper left side of the vertical baffle section 2.

When the force is removed, the elastic force is returned.

[0046] In any of the above solutions, preferably, the torsion assembly includes a sleeving disc 6 movably sleeved on the outer side wall of the horizontal fixed shaft 4.

At this time, the patient operates the rotating and twisting handle 9 to drive the whole torsion disc 8 to rotate to achieve the purpose of exercising the arm activity. In the rotating process, the torsion force of the torsion spring 7 needs to be overcome to achieve the purpose of exercise.

[0050] The sleeve joint disc 6 is locked by controlling the left and right extension of the horizontal locking screw 10, and is unlocked by controlling the right extension. When the sleeve joint disc 6 is unlocked, the whole sleeve joint disc 6 can swing and rotate within a certain rotation angle range. Therefore, the force used by the patient is different when the rotating and twisting handle 8 is operated and locked with the sleeve joint disc 6. Therefore, different gear torsion exercises can be achieved, so as to achieve the purpose of exercising the arm in different degrees.

[0051] In any of the above schemes, it is preferred that a protective sleeve 12 is fixed on the outer wall of each rotating and twisting handle 9; and two gripping and pulling handles 13 are fixed and installed on the outer wall of the torsion disc 8 along the circumference and symmetrically and at intervals.

[0053] In any of the above schemes, it is preferred that the displacement mechanism comprises a fixed reciprocating push-pull cylinder group 14, the reciprocating push-pull cylinder group 14 is composed of two mutually parallel push-pull cylinders, the front end of the piston rod of each push-pull cylinder is fixedly installed at the left end face of a sliding seat 15, a plurality of moving wheels 16 are installed at the bottom of the sliding seat 15 at intervals, and the bottom of each moving wheel 16 abuts against the top of the installation base 1.

[0054] When the displacement mechanism is displaced, the sliding seat 15 at the right end is driven to move by the extension and retraction of the reciprocating push-pull cylinder group 14. Since the moving wheels 16 are installed at the bottom of the sliding seat 15, the sliding seat 15 can be guaranteed to be smooth and stable during displacement.

[0061] A leg rehabilitation driving member is installed above the driving pulley 19.

[0062] The leg exercise mechanism can swing the lower legs of the patient reciprocally when the patient sits, so as to promote the blood circulation of the lower legs.

[0063] In specific work, the leg rehabilitation driving member drives the driving pulley 19 to rotate, so that the left foot placing box 22 and the right foot placing box 23 can be driven to move back and forth in opposite directions under the action of the tooth-shaped transmission belt 21. In the moving process of the left foot placing box 22 and the right foot placing box 23, the left leg and the right leg of the patient placed thereon are also moved, so as to finally exercise the lower leg. The number of forward rotation and the number of reverse rotation of the leg rehabilitation driving member are set in advance when the leg rehabilitation driving member is controlled to operate, so as to drive the left foot placing box 22 and the right foot placing box 23 to move without interfering with the motion of the driving pulley 19 and the driven pulley 18 at both ends.

[0064] The limiting fixing plate 20 arranged herein mainly serves to limit the driven pulley 18 and the driving pulley 19 in the up-down direction, so as to prevent the driven pulley 18 and the driving pulley 19 from jumping up and down.

[0070] The application also provides an assembly method of the safety adjustable rehabilitation device, and the specific steps include:

[0071] Install displacement mechanism: according to the requirements of the two push-pull cylinder fixed installation, then in each push-pull cylinder piston rod end fixed installation sliding seat 15;

[0072] Install massage chair seat 3: install massage chair seat 3 on the top of the corresponding sliding seat 15;

[0073] The installation worker according to need sit on massage chair seat 3 and by another operator pull arm torsion mechanism, installation when pre by sit staff position height control, control after the completion of the pull arm torsion mechanism positioning, realize the installation of pull arm torsion mechanism:

[0074] After the installation of pull arm torsion mechanism, according to need install leg exercise mechanism, after installation start the rehabilitation device and try, up to standard after the completion of the whole rehabilitation device assembly and debugging.

[0075] Specific working principle:

[0076] The safety type adjustable rehabilitation device needs the patient to sit on the massage chair seat 3 of the application first, adjust the displacement mechanism to the appropriate position through the button or remote control, adjust the comfort of the current position by holding the pull arm torsion mechanism with both arms, and fine tune as needed. After the position is adjusted, the patient's hands hold the pull arm torsion mechanism to rotate the pull arm torsion mechanism through the cross of both arms to achieve the purpose of exercising the arms. The whole structure of the pull arm torsion mechanism relies on the horizontal fixed shaft 4 to realize the fixed shaft support. Because the push-pull spring 5 is provided, when the arm strength needs to be exercised, the torsion assembly can be pulled to the side close to the body to overcome the elastic force of the push-pull spring 5 according to the direction of the patient's body to achieve the purpose of exercising the arm proportion. When the force is removed, the elastic force is returned.

[0077] The torsion assembly mainly relies on the adjustment knob lock handle 11 to rotate the front end of the horizontal lock screw 10 to the left side of the sleeve joint disc 6 and lock the sleeve joint disc 6 during operation. At this time, the patient operates the rotating and twisting grip handle 9 with both hands to drive the reciprocating fixed shaft rotation of the whole torsion disc 8 to achieve the purpose of exercising the arm activity. In this rotating process, the torsion of the torsion spring 7 needs to be overcome to achieve the purpose of exercise. By controlling the left and right extension of the horizontal lock screw 10, the sleeve joint disc 6 is locked or unlocked. When the sleeve joint disc 6 is unlocked, the whole sleeve joint disc 6 can swing within a certain range of rotation angle, so the force used by the patient is different when the rotation of the torsion disc 8 is operated and locked with the sleeve joint disc 6. Therefore, different gear torsion exercises can be achieved to achieve different degrees of arm exercise. When the horizontal lock screw 10 moves to the right and unlocks the sleeve joint disc 6, the grip push-pull handle 13 can be held to pull to the side of the body to achieve the purpose of arm strength exercise.

[0078] The leg exercise mechanism can reciprocally swing the lower legs of the patient when the patient is sitting, so as to promote blood circulation of the lower legs. In operation, the leg rehabilitation driving member drives the driving pulley 19 to rotate, so as to reciprocally move the left foot placing box 22 and the right foot placing box 23 in opposite directions under the action of the tooth-shaped transmission belt 21. In the moving process of the left foot placing box 22 and the right foot placing box 23, the left leg and the right leg of the patient placed thereon are moved, so as to exercise the lower legs. The number of forward rotation and the number of reverse rotation of the leg rehabilitation driving member are set in advance when the leg rehabilitation driving member is controlled to operate, so as to move the left foot placing box 22 and the right foot placing box 23 without interfering with the motion of the driving pulley 19 and the driven pulley 18 at both ends. The limiting fixed plate 20 is mainly used to limit the driving pulley 19 and the driven pulley 18 in the up-down direction, so as to prevent the driving pulley 19 and the driven pulley 18 from jumping up and down.
