[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] This utility model discloses a nursing and rehabilitation device for movable lower limbs, such as... Figure 1-8 As shown, the device includes a seat 1, with a rotating shaft 2 rotatably connected to the front side of the seat 1. A rehabilitation frame 3 for lower limb movement is fixedly installed on the outer surface of the rotating shaft 2. The user fixes their lower limbs on the rehabilitation frame 3, and then the user rotates the rehabilitation frame 3 through the rotating shaft 2, causing the user's lower limbs to bend and extend, so as to achieve the effect of lower limb rehabilitation care for the user.

[0026] Both sides of the rotating shaft 2 are slidably connected to movable rods 201. The cross-sectional shape of the two movable rods 201 is rectangular. The ends of the two movable rods 201 extending to the outside of the rotating shaft 2 are fixedly installed with a first gear 202. A connecting block 205 is fixedly installed on one side of the outer surface of the two movable rods 201. A first threaded rod 203 is rotatably connected to the outer surface of the rotating shaft 2. Both connecting blocks 205 extend to the outside of the rotating shaft 2 and are threadedly connected to the first threaded rod 203. A drive assembly is provided on one side of the base.

[0027] The outer surface of the first threaded rod 203 is provided with two opposite threads. A handle 204 is fixedly installed at one end of the first threaded rod 203. When the handle 204 is manually held and rotated, the first threaded rod 203 will be rotated. As the first threaded rod 203 rotates, the two movable rods 201 can move in opposite directions, thereby adjusting the distance between the two first gears 202.

[0028] The drive assembly includes a rotating rod 102 rotatably connected to one side of the seat 1. Both ends of the rotating rod 102 extend to the outside of the seat 1 and are fixedly mounted with a second gear 103. A motor 101 is fixedly mounted on one side of the seat 1, and the output shaft of the motor 101 is fixedly connected to the rotating rod 102.

[0029] Motor 101 is a DC brushed motor 101, which is powered by an external power source and controlled by a controller. The controller controls the rotation direction of the output shaft of motor 101 by changing the current direction, and adjusts the speed by switching the power supply on and off or by using a PWM signal to control the start and stop of the output shaft of motor 101.

[0030] Users can control the rotation direction and start / stop of the device by operating the controller. This control method is existing technology, so it will not be described in detail here.

[0031] The motor 101 drives the rotating rod 102 to rotate, which in turn causes the two second gears 103 to rotate. When the two first gears 202 mesh with the two second gears 103 respectively, the rotating second gears 103 will drive the first gears 202 to rotate, which in turn causes the rotating shaft 2 to drive the rehabilitation frame 3 to rotate, so as to achieve the effect of passive rehabilitation exercise for the user's lower limbs.

[0032] A fixing rod 1021 is fixedly installed at the bottom of the seat 1. Multiple elastic ropes 1022 are provided on the outer surface of the fixing rod 1021. A hook 302 is fixedly installed at the end of the elastic rope 1022 away from the fixing rod 1021. A connecting rod 301 is fixedly installed on the rear side of the outer surface of the rehabilitation frame 3, and the hook 302 is located outside the connecting rod 301. When the second gear 103 is not engaged with the first gear 202, the hook 302 can be hung on the outside of the connecting rod 301. Then, the user exerts force with his / her lower limbs to make the rehabilitation frame 3 rotate. When the rehabilitation frame 3 rotates, it will stretch the elastic ropes 1022. Through the elasticity of the elastic ropes 1022, the effect of active rehabilitation exercise for the user's lower limbs can be achieved. The user can hang different numbers of hooks 302 on the connecting rod 301 according to his / her needs.

[0033] Two placement blocks 303 are fixedly installed on both sides of the outer surface of the rehabilitation frame 3. Fixing straps 304 are fixedly installed on one side of each of the four placement blocks 303, and multiple buckle holes 308 are opened on one side of each of the four fixing straps 304. Buttons 309 are fixedly installed on one side of each of the four placement blocks 303. The user places his lower limbs on the placement blocks 303 and fixes his lower limbs by passing the buttons 309 through the buckle holes 308.

[0034] The rehabilitation frame 3 has two second threaded rods 305 rotatably connected to both sides of its bottom, and two slide rods 307 are fixedly installed on both sides of its bottom. The outer surfaces of the two second threaded rods 305 are threaded with support plates 306, and the two support plates 306 are slidably connected to the four slide rods 307 respectively. The bottom ends of the two second threaded rods 305 are fixedly installed with handles 3071. Caregivers can manually rotate the handles 3071 to rotate the second threaded rods 305, thereby moving the support plates 306 along the slide rods 307 to adjust the position of the support plates 306 so that the feet of users with different lower limb lengths can be placed on the support plates 306.

[0035] The support plate 306 can also be configured to be movable forward and backward, or to assist in plantar flexion and dorsiflexion movements, thereby achieving active and passive plantar flexion and dorsiflexion functions.

[0036] The working principle of this utility model is as follows: The user first sits on the seat 1, places his feet on the support plate 306, and places his lower limbs against the placement block 303. Then, the user fixes his lower limbs with the fixing strap 304, and then he can carry out rehabilitation exercises.

[0037] During passive rehabilitation exercises, the caregiver manually holds and rotates the handle 204 to rotate the first threaded rod 203. As the first threaded rod 203 rotates, the two movable rods 201 move in opposite directions, thereby adjusting the distance between the two first gears 202 until the two first gears 202 mesh with the two second gears 103. Then, the caregiver starts the motor 101 through the controller. The motor 101 drives the rotating rod 102 and the two second gears 103 to rotate. The rotating second gears 103 then drive the first gears 202 to rotate, thereby causing the rotating shaft 2 to drive the rehabilitation frame 3 to rotate, so as to perform passive rehabilitation exercises on the user's lower limbs.

[0038] During active rehabilitation exercises, the caregiver rotates the first threaded rod 203 again, so that the two first gears 202 do not mesh with the two second gears 103, and hangs the hook 302 on the connecting rod 301. The user exerts force through the lower limbs to make the rehabilitation frame 3 rotate. When the rehabilitation frame 3 rotates, it will stretch the elastic rope 1022. Through the elasticity of the elastic rope 1022, the effect of active rehabilitation exercises for the user's lower limbs can be achieved. The user can hang different numbers of hooks 302 on the connecting rod 301 according to their own needs.

[0039] When rotating axis 2, the rotation angle can be limited, such as adjustable from 0 to 60 degrees. A display device can also be set to display the rotation angle in real time, so as to see the progress of the exercise process more intuitively.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
