Technical Field

[0001] The utility model belongs to the technical field of lower limb lifting, and in particular relates to a lower limb lifting device which is convenient for turning over a body. Background Art

[0002] When a person is resting in bed due to foot and ankle injuries, the lower limbs will be lifted to accelerate blood circulation in the lower limbs, and a lower limb lifting device is required. The current lower limb lifting device lifts the legs by supporting them from below or by hanging them. However, during use, the longitudinal position and angle of the person's legs are restricted. When the person forcibly turns the body over, the legs will experience obvious twisting discomfort, which further causes the person to remain in a supine position to adapt to the position of the legs. The body cannot be turned over to adjust the body's lying position. When the person remains in a supine position for a long time, physical discomfort will occur. Utility Model Content

[0019] See also Figure 1-Figure 5The utility model provides the following technical solutions: a lower limb lifting device that is convenient for body flipping, comprising a lower limb supporting arc plate 1, the inner wall of the lower limb supporting arc plate 1 is fixedly connected with a binding belt 11, the outer wall of the lower limb supporting arc plate 1 is rotatably connected with a flip angle compensation arc frame 2, the outer wall of the flip angle compensation arc frame 2 is rotatably connected with a suspension connection frame 3, the top of the suspension connection frame 3 is fixedly connected with a suspension rope 31, the top of the suspension rope 31 is slidably connected with a flip movement distance compensation slot plate 4, and an angle adjustment dial 41 is installed on one side of the flip movement distance compensation slot plate 4.

[0020] In this embodiment: the driving motor connected to the rear of the angle adjustment turntable 41 is controlled by the controller to open and close and rotate, and the support plate frame 43 is placed at the end of the bed. When the left leg is lifted, the lower limb support arc plate 1 is adjusted to be located below the left side of the flip moving distance compensation slot plate 4. When the right leg is lifted, the lower limb support arc plate 1 is adjusted to be located below the right side of the flip moving distance compensation slot plate 4. The user's legs are placed on the inner side of the lower limb support arc plate 1, and the legs are fixed with the binding belt 11. The lower limb support arc plate 1, the flip angle compensation arc frame 2, the suspension connection frame 3 and the flip moving distance compensation slot plate 4 cooperate to suspend and support the user's lower limbs. When the body needs to be flipped, the controller controls the driving motor to drive the flip moving distance compensation slot plate 4 and the angle adjustment turntable 41 to flip and tilt. The person then slowly turns his body over. During the turning process, the lower limb support arc plate 1 rotates in the turning angle compensation arc frame 2 to adjust the turning angle of the user's legs to compensate for the turning angle of the legs when the person turns over. The relative displacement of the suspension rope 31 and the turning movement distance compensation slot plate 4 can compensate for the moving distance of the leg position when the person's body turns over. After the person's body is turned over, the device still maintains an upward support force for the person's legs and does not apply a force tending to reset the person's legs. The angle adjustment dial 41 adjusts the angle of the turning movement distance compensation slot plate 4, which can reduce the force of the legs driving the suspension connection frame 3 to move when the human body turns over, so that the user can easily turn his body over, improve the user's bed comfort, and avoid the person from maintaining the same bed posture for a long time and causing physical discomfort.

[0021] A protective pad 12 is fixedly connected to the inner wall of the lower limb support arc plate 1, and a friction pad layer 13 is fixedly connected to the outer wall of the protective pad 12; by setting the protective pad 12, soft support can be provided to improve the comfort of the person's legs, and the friction pad layer 13 can increase the friction with the person's legs and improve the stability of the lower limb support arc plate 1 wrapped around the person's legs.

[0022] A connecting spring 32 is fixedly connected to the suspension rope 31, and a protective sleeve 321 is provided on the outside of the connecting spring 32; by setting the connecting spring 32, when the person's legs shake, the overall length of the suspension rope 31 can be adaptively adjusted to improve the person's comfort, and the protective sleeve 321 wrapped around the outside plays a protective role.

[0023] The top end of the suspension rope 31 is fixedly connected to a connecting slider 33, and the connecting slider 33 is slidably connected to the inner wall of the flip movement distance compensation slot plate 4; by setting the connecting slider 33, the connection between the suspension rope 31 and the flip movement distance compensation slot plate 4 can be facilitated, and the connecting slider 33 slides in the flip movement distance compensation slot plate 4, so that the relative displacement of the suspension rope 31 and the flip movement distance compensation slot plate 4 is smoother.

[0024] The bottom end of the suspension connecting frame 3 is fixedly connected to a connecting shaft 34, which is fixedly connected to the outer wall of the flip angle compensation arc frame 2. The suspension connecting frame 3 is rotatably connected to the flip angle compensation arc frame 2 through the connecting shaft 34; by setting the connecting shaft 34, the change of the angle between the suspension connecting frame 3 and the flip angle compensation arc frame 2 can be facilitated to adapt to the angle of the person's legs.

[0025] An "L"-shaped extended support plate 42 is fixedly connected to the side wall of the angle adjustment turntable 41, and a support plate frame 43 is fixedly connected to one side of the "L"-shaped extended support plate 42; by setting the "L"-shaped extended support plate 42 and the support plate frame 43, the angle adjustment turntable 41 and the flipping movement distance compensation slot plate 4 can be supported, and at the same time, the "L"-shaped extended support plate 42 plays an extension role to provide accommodation space for the feet of the person, thereby preventing the feet of the person from touching the support plate frame 43 and being injured again.

[0026] The central angle of the lower limb support arc plate 1 and the flip angle compensation arc frame 2 is greater than one hundred and eighty degrees, and the central angle of the lower limb support arc plate 1 is greater than the central angle of the flip angle compensation arc frame 2; the lower limb support arc plate 1 and the flip angle compensation arc frame 2 are provided with notches to facilitate the placement of the person's legs. The central angle greater than one hundred and eighty degrees enables the lower limb support arc plate 1 to move smoothly in the flip angle compensation arc frame 2, avoiding the lower limb support arc plate 1 and the flip angle compensation arc frame 2 from losing contact after the rotation angle is too large.

[0027] The working principle and usage process of the present invention are as follows: the support plate frame 43 is placed at the end of the bed. When lifting the left leg, the lower limb support arc plate 1 is adjusted to be located below the left side of the flip movement distance compensation slot plate 4. When lifting the right leg, the lower limb support arc plate 1 is adjusted to be located below the right side of the flip movement distance compensation slot plate 4. The user's legs are placed on the inner side of the lower limb support arc plate 1 and the legs are fixed with the binding belt 11. When the body needs to be flipped, the controller controls the driving motor to drive the flip movement distance compensation slot plate 4 and the angle adjustment turntable 41 to flip and tilt. Then the person slowly flips the body. During the flipping process, the lower limb support arc plate 1 rotates in the flip angle compensation arc frame 2 to adjust the flip angle of the user's legs to compensate for the flip angle of the legs when the person flips. The relative displacement of the suspension rope 31 and the flip movement distance compensation slot plate 4 can compensate for the moving distance of the leg position when the person's body is flipped. After the flipping is completed, the flip movement distance compensation slot plate 4 is adjusted again to rotate to the appropriate angle according to needs.
