[0032] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0033] It should be noted that all directional indications in the embodiments of the present application are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0034] In this application, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0035] When the existing device is in use, the patient needs to be helped by medical staff to sit on a rehabilitation chair for rehabilitation training. The patient puts his legs on the guard plate, and the medical staff controls the rotation of the guard plate to assist the patient's calf and knee to move. The patient's upper limbs are trained through other components such as external rings.

[0036] In the related technology, the existing cardiovascular rehabilitation devices usually only provide auxiliary training for the patient's knees and calves, and there is no way to take care of the rehabilitation training of the patient's thighs and hips. In addition, during the exercise process, the patient's thighs are prone to numbness after not exercising for a long time, which has certain limitations.

[0037] In order to solve the problems in the related art to a certain extent, the embodiment of the present application provides a cardiovascular rehabilitation chair. When it is needed, the patient only needs to be helped to sit on the cushion 14 with the help of medical staff, and the height of the cushion 14 can be adjusted by controlling the electric telescopic rod 13 according to the patient's height and body shape. The patient leans back against the backrest 16 and puts his hands on the armrests 15. The medical staff then puts the patient's feet on the footrest 233 and starts the reversible motor 221. The reversible motor 221 drives the gear 22 to rotate clockwise first, and the gear 22 and the rack 231 are meshed and connected. Therefore, the gear 22 drives the rack 231 on one side to rise and the rack 231 on the other side to fall. Therefore, the footrest 233 fixedly connected to the rack 231 through the connecting piece 232 rises or falls synchronously, driving the patient's feet to rise and fall. The movement of the patient's feet can drive the legs to bend, and the thigh, calf and knee parts are effectively exercised, thereby improving the effect of the entire rehabilitation exercise.

[0038] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0039] Combination Figure 1-Figure 5 The embodiment of the present application provides a cardiovascular rehabilitation chair, including a rehabilitation chair assembly 1; the rehabilitation chair assembly 1 includes: a universal wheel 12 is arranged at the bottom of a base 11, an electric telescopic rod 13 is arranged on the base 11, a seat cushion 14 is arranged on the top of the electric telescopic rod 13, and an armrest 15 and a backrest 16 are arranged on the seat cushion 14; a training assembly 2 is arranged on the rehabilitation chair assembly 1, and the training assembly 2 includes: a guard plate 21 is rotatably arranged on the seat cushion 14, and a slide groove 211 is arranged on the guard plate 21, A reversible motor 221 is provided through the guard plate 21; a gear 22 is provided inside the guard plate 21, and an output end of the reversible motor 221 is fixedly connected to the gear 22; a second slide groove 23 is provided on both sides of the gear 22, a rack 231 is slidably connected to the second slide groove 23, the rack 231 is meshedly connected to the gear 22, a connecting member 232 is fixedly connected to the rack 231, the connecting member 232 is slidably connected to the slide groove 1 211, and a footrest 233 is provided on the connecting member 232.

[0040] When it is needed, the patient only needs to be helped to sit on the cushion 14 with the help of the medical staff, and the height of the cushion 14 can be adjusted by controlling the electric telescopic rod 13 according to the patient's height and body shape. The patient leans back against the backrest 16 and puts his hands on the armrests 15. The medical staff then puts the patient's feet on the footrest 233 and starts the reversible motor 221. The reversible motor 221 drives the gear 22 to rotate clockwise first, and the gear 22 and the rack 231 are meshed and connected. Therefore, the gear 22 drives the rack 231 on one side to rise and the rack 231 on the other side to fall. Therefore, the footrest 233 fixedly connected to the rack 231 through the connecting piece 232 rises or falls synchronously, driving the patient's feet to rise and fall. The movement of the patient's feet can drive the legs to bend, and the thigh, calf and knee parts are effectively exercised, thereby improving the effect of the entire rehabilitation exercise. The patient's upper limbs are rehabilitated through other components such as external rings.

[0041] In some embodiments, the guard plate 21 and the seat cushion 14 are rotatably connected via a rotating shaft, and a threaded member is provided at the connection. The user can rotate the threaded member to make the guard plate 21 rotate freely, and then tighten the threaded member after rotating to a suitable angle to fix the guard plate 21 at the adjusted angle to meet the user's usage needs.

[0042] In some embodiments, a slider is provided at the bottom of the rack 231 and is slidably connected to the second slide groove 23. The rack 231 and the second slide groove 23 are slidably connected by the slider to improve the smoothness of the movement of the rack 231.

[0043] In some embodiments, a limit block 234 is provided on the second slide groove 23. Four limit blocks 234 are provided, respectively at the two ends of the second slide groove 23, to prevent the slider at the bottom of the rack 231 from derailing on the second slide groove 23.

[0044] In some embodiments, the connector 232 is in an I-shape. The connector 232 is in an I-shape, and its bottom is fixedly connected to the rack 231. The larger the contact area, the greater the bearing capacity of the rack 231. At the same time, the middle section of the connector 232 is thinner and is slidably connected to the slide groove 1 211. The opening of the slide groove 1 211 is small to prevent dust from entering and hindering the normal operation of the component. The top of the connector 232 has a large contact area with the footrest 233, and the fixed connection between the two is more secure.

[0045] In some embodiments, the footrest 233 is provided with a bidirectional screw 24, the bidirectional screw 24 is threadedly connected with a moving block 241, the moving block 241 is provided with a clamping arm 242, the clamping arm 242 penetrates the footrest 233 and is slidably connected to the footrest 233. The user can control the bidirectional screw 24 to rotate, so that the moving block 241 moves in opposite directions on the bidirectional screw 24, and control the clamping arm 242 to move in opposite directions, so as to clamp the patient's foot and improve the stability of the patient's foot moving on the footrest 233.

[0046] In some embodiments, one end of the bidirectional screw 24 passes through the footrest 233 and is fixedly connected to a knob 244. The user can control the rotation of the bidirectional screw 24 through the sawtooth knob 244, which facilitates the user to apply force to control the rotation angle of the bidirectional screw 24, thereby controlling the spacing of the clamp arms 242.

[0047] In some embodiments, a sponge pad 243 is provided on the clamp arm 242. The sponge pad 243 is soft and has a protective effect on the patient's feet.
