[0029] Further explanation is needed: A fixing plate 2 is placed on top of the main body 1 of the hospital bed. The fixing plate 2 is fixed to the main body 1 of the hospital bed by the bottom fixing Velcro strap 1 201 and fixing Velcro strap 202. A positioning plate 203 is provided on one side of the fixing plate 2. When the fixing plate 2 is fixed to the top of the main body 1 of the hospital bed, the positioning plate 203 contacts the connecting plate 103. An adjustment mechanism 3 and an exercise mechanism 4 are provided inside the fixing plate 2. The adjustment mechanism 3 makes it easy to adjust the position of the exercise mechanism 4, and the exercise mechanism 4 makes it easy for patients to perform leg rehabilitation exercises.

[0030] Please see Figure 4-6 The present invention provides the following technical solution:

[0031] The exercise mechanism 4 includes a pedal 401, an anti-slip strip 402, a traction spring 403, a connecting block 404, and a threaded hole 405. The pedal 401 is slidably connected to the top of the fixed plate 2. An anti-slip strip 402 is provided on one side of the pedal 401. A traction spring 403 is fixedly snapped onto one side of the pedal 401. A connecting block 404 is fixedly snapped onto one side of the traction spring 403. A threaded hole 405 is provided on one side of the connecting block 404.

[0032] The pedal 401 is slidably connected inside the slide groove 303, and the pedal 401 is slidably sleeved on the outer surface of the limit rod 304.

[0033] The traction spring 403 is movably sleeved on the outer surface of the limiting rod 304, and the connecting block 404 is slidably sleeved on the outer surface of the limiting rod 304.

[0034] The connecting block 404 is slidably connected inside the through groove 305, and the connecting block 404 is set on the outer surface of the lead screw 301.

[0035] Further explanation is needed: When the patient lies on the main body 1 of the hospital bed, both legs are placed on the fixed plate 2, and the feet are in contact with the pedal 401. When leg exercises are needed, the patient pushes the pedal 401 forward by kicking the legs forward. Since the bottom of the pedal 401 is connected to the traction spring 403 and the traction spring 403 is pulled by the connecting block 404, there will be a certain resistance during the forward movement of the pedal 401 to achieve the exercise function. When the patient retracts the legs, the traction spring 403 can pull the pedal 401 backward to reset and assist the patient in retracting the legs. This process can be repeated to exercise both legs.

[0036] Please see Figure 4-6 The present invention provides the following technical solution:

[0037] The adjusting mechanism 3 includes a lead screw 301, a throttle 302, a slide groove 303, a limit rod 304, a through groove 305, and a connecting hole 306. The lead screw 301 is rotatably connected to the inside of the fixed plate 2. The throttle 302 is fixedly connected to one side of the lead screw 301. The slide groove 303 is opened on the top of the fixed plate 2. The limit rod 304 is fixedly connected inside the slide groove 303. A through groove 305 is opened on one side of the slide groove 303, and a connecting hole 306 is opened on one side of the through groove 305.

[0038] The lead screw 301 is threaded into the inside of the threaded hole 405, and the lead screw 301 is rotatably connected into the inside of the connecting hole 306.

[0039] Further explanation is needed: When the handle 302 is held and rotated in the forward direction, the rotating handle 302 drives the lead screw 301 to rotate, pushing the connecting block 404 backward. The backward-moving connecting block 404 pulls the traction spring 403 to extend. At this time, the patient can clearly feel the increase in the required pedal force when pushing the pedal 401 forward. When the handle 302 is rotated in the reverse direction, the force required for the patient to push the pedal 401 forward will be reduced.

[0040] Working principle: When an orthopedic leg rehabilitation exercise device is used, a fixing plate 2 is first placed on the top of the bed body 1. The fixing plate 2 is fixed to the bed body 1 by the bottom fixing Velcro strap 1 201 and fixing Velcro strap 202. A positioning plate 203 is set on one side of the fixing plate 2. When the fixing plate 2 is fixed on the top of the bed body 1, the positioning plate 203 contacts the connecting plate 103. An adjustment mechanism 3 and an exercise mechanism 4 are set inside the fixing plate 2. The adjustment mechanism 3 makes it easy to adjust the position of the exercise mechanism 4, and the exercise mechanism 4 makes it easy for the patient to perform leg rehabilitation exercises.

[0041] When leg exercises are needed, the patient lies on the main body 1 of the bed with both legs placed on the fixed plate 2 and the feet in contact with the pedal 401. When leg exercises are needed, the patient pushes the pedal 401 forward by kicking the legs. Since the bottom of the pedal 401 is connected to the traction spring 403 and the traction spring 403 is pulled by the connecting block 404, there will be a certain resistance during the forward movement of the pedal 401 to achieve the exercise function. When the patient retracts the legs, the traction spring 403 can pull the pedal 401 backward to reset and assist the patient in retracting the legs. This process can be repeated to exercise both legs. This device is convenient for exercising the patient's legs.

[0042] When it is necessary to adjust the intensity of leg rehabilitation exercises, first hold the handle 302 and rotate it clockwise. The rotating handle 302 drives the lead screw 301 to rotate, pushing the connecting block 404 backward. The backward-moving connecting block 404 pulls the traction spring 403 to extend. At this time, the patient can clearly feel the increase in the required pedal force when pushing forward on the pedal 401. When rotating the handle 302 in the opposite direction, the force required for the patient to push forward on the pedal 401 can be reduced. This device makes it easy to adjust the intensity of leg rehabilitation exercises.

[0043] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
