Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] According to the following Figure 1 - Figure 7 The invention describes a recovery and exercise wheelchair for patients with diabetic foot provided by an embodiment of the utility model.

[0027] See also Figure 1 As shown, the utility model discloses a recovery and exercise wheelchair for diabetic foot patients, including a chair frame 300 and a base 200, wherein the base 200 is located on one side below the chair frame 300, and footrests 400 are arranged on both sides above the base 200, and the two footrests 400 are used to place the feet.

[0028] Combination Figure 1 - Figure 2 As shown, a cam 800 is also provided. The cam 800 is located in the base 200 at a position opposite to the pedal 400, and the two cams 800 are symmetrically arranged with the midline of the two pedals 400 as the symmetry axis. A driving mechanism for driving the two cams 800 to rotate synchronously is provided in the base 200, so that when the driving mechanism is working, the two cams 800 can alternately lift the pedal 400, so that the two pedals 400 can alternately lift the foot, so that the patient can do small-amplitude exercises similar to walking, so as to exercise the lower limbs of diabetic patients.

[0029] like Figure 3 In order to enable the pedal 400 lifted by the cam 800 to rebound downward, a reset assembly 700 is provided. The reset assembly 700 is provided between the base 200 and the pedal 400, and the reset assembly 700 is used for the rebound after the pedal 400 is lifted by the cam 800.

[0030] like Figure 4 and Figure 5 As shown, the footrest 400 mentioned above includes a base plate 420 and a twisting plate 410 which are arranged in sequence from bottom to top. The patient's foot is supported on the twisting plate 410. The upper surface of the twisting plate 410 has anti-slip grooves to prevent the patient's foot from falling off the twisting plate 410. A rotating shaft 430 is fixed at the lower end of the twisting plate 410, and an integrated limiting shaft 450 is provided at the lower end of the rotating shaft 430. The rotating shaft 430 and the limiting shaft 450 are rotatably installed in the base plate 420, so that the twisting plate 410 can rotate on the base plate 420.

[0031] In this embodiment, when the patient's foot is supported on the twisting plate 410, the patient can reciprocately twist his or her foot to make the twisting plate 410 swing left and right on the bottom plate 420 at a certain angle, thereby exercising the ankle.

[0032] Preferably, a torsion spring 440 is provided between the limiting shaft 450 and the bottom plate 420. The torsion spring 440 can increase the resistance when the torsion plate 410 and the limiting shaft 450 rotate, thereby improving the comfort of the foot twisting and avoiding excessive twisting.

[0033] Combination Figure 2 - Figure 4 and Figure 7 As shown, preferably, protrusions 210 are provided at positions opposite to the cam 800 on both sides of the base 200 , and the protrusions 210 are used to install the reset assembly 700 .

[0034] The reset assembly 700 mentioned above includes an assembly tube 720 fixed in the protrusion 210, a guide rod 710 inserted into the assembly tube 720 from the upper end, a pressure ring 711 fixed to the lower end of the guide rod 710, and a spring 730 for connecting the pressure ring 711 and the bottom surface of the assembly tube 720. The upper end of the guide rod 710 is fixedly connected to the bottom surface of the pedal 400.

[0035] In this embodiment, when the cam 800 pushes the pedal 400 upward, the pedal 400 pulls the guide rod 710 upward, and the guide rod 710 stretches the spring 730 upward. Conversely, when the cam 800 no longer pushes the pedal 400, the spring 730 is reset, and the guide rod 710 can pull the pedal 400 down to achieve reciprocating lifting and lowering of the pedal 400.

[0036] Combination Figure 4 and Figure 6 As shown, the above-mentioned driving mechanism includes a worm wheel 650 fixed at one end of the axis of the cam 800, a worm portion 640 meshing with one side of the worm wheel 650, and a rotating rod 630 for connecting the two worm portions 640. The rotating rod 630 is used to drive the worm portion 640 to rotate. By rotating the worm portion 640, the worm wheel 650 drives the cam 800 to rotate, thereby realizing the reciprocating lifting and lowering of the pedal 400.

[0037] In order to realize the rotation of the above-mentioned rotating rod 630, a driven gear 620 is fixedly provided in the middle of the rotating rod 630, and a main gear 610 is meshed above the driven gear 620. A motor 600 for driving the main gear 610 to rotate is provided on the base 200. Through the operation of the motor 600, the main gear 610 and the driven gear 620 drive the rotating rod 630 to rotate.

[0038] like Figure 1 and Figure 2As shown, in order to make the angle of the base 200 adjustable so that the patient can find a comfortable foot placement angle, a protrusion 310 is installed at the lower end of the chair frame 300, and an adjustment shaft is provided between the protrusion 310 and the base 200. The base 200 can rotate on the adjustment shaft to adjust its own angle on the adjustment shaft to adapt to different foot placement angles.

[0039] In addition, it is best to sleeve a friction-increasing rubber ring on the outer part of the circumference of the adjustment shaft located inside the base 200 to achieve stability of the base 200 after the angle is adjusted.

[0040] like Figure 1 A chair body 100 is installed on the upper surface of the chair frame 300 , and wheels 500 are provided below both sides of the chair frame 300 .

[0041] The working principle and use process of the utility model are as follows: when in use, the patient sits on the chair body 100 and places the feet on the twisting plate 410. The patient can twist the feet left and right, and the twisting plate 410 can rotate on the bottom plate 420, so that the patient can exercise the ankle.

[0042] The patient can also exercise the entire leg and foot, that is, when the motor 600 is working, the main gear 610 and the driven gear 620 drive the rotating rod 630 to rotate, and the rotating rod 630 is used to drive the worm part 640 to rotate. By the rotation of the worm part 640, the worm wheel 650 drives the cam 800 to rotate. When the cam 800 pushes the pedal 400 upward, the pedal 400 pulls the guide rod 710 upward, and the guide rod 710 stretches the spring 730 upward. Conversely, when the cam 800 no longer pushes the pedal 400, the spring 730 is reset, and the pedal 400 can be pulled down by the guide rod 710 to realize the reciprocating lifting of the two pedals 400, so that the patient can do small-amplitude exercises similar to walking to exercise the lower limbs of diabetic patients.

[0043] To summarize, the recovery and exercise wheelchair for diabetic foot patients has two cams 800 arranged in the base 200, so that when the driving mechanism is working, the two cams 800 can alternately lift the footrests 400, so that the two footrests 400 can alternately lift the feet, and the patient can do small-amplitude exercises similar to walking, so as to exercise the lower limbs of diabetic patients and avoid discomfort caused by excessive movements; when the foot is supported on the twist plate 410, the patient can make the twist plate 410 swing left and right at a certain angle on the bottom plate 420 by twisting his or her foot back and forth, thereby exercising the ankle.
