DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0023] Please refer to Figures 1-4The utility model provides a technical scheme: a leg rehabilitation training device, include: bottom plate 1, the upper surface both sides of bottom plate 1 are rotationally connected with gyro wheel 2, the gyro wheel 2 front surface of right side is connected with brushless motor 3, the inside pivot of brushless motor 3 is connected with right side gyro wheel 2 inside fixedly, the outside of two gyro wheel 2 is equipped with belt 4, the upper surface middle part of belt 4 is connected with sliding block 5, the upper surface of bottom plate 1 is equipped with shell 6, the inside of shell 6 is equipped with slide groove 7, sliding block 5 is inserted into the inside connection of slide groove 7, the middle fixed connection of sliding block 5 is equipped with rotating rod 8, the front and back both sides of rotating rod 8 extend to the outside of shell 6, the front and back both ends of rotating rod 8 are equipped with connecting support 9, the inside rotationally connected of connecting support 9 is equipped with chuck 10, the inside rotationally connected of chuck 10 is equipped with sole support 19, the inside upper end connection of chuck 10 is equipped with calf outside support 11, the left side connection of calf outside support 11 is equipped with pivot 12, the outside lower end connection of pivot 12 is equipped with thigh support 13, the outside of two calf outside support 11 is equipped with calf connecting pad 14, the upper surface middle part of calf connecting pad 14 is connected with calf fixed sleeve 15, the outside of two thigh support 13 is equipped with thigh connecting pad 16, the upper surface middle part of thigh connecting pad 16 is connected with thigh fixed sleeve 17, the right side rotationally connected of shell 6 is equipped with controller 18, the electric connection between controller 18 and brushless motor 3.

[0024] When using, the user places the calf on the calf connecting pad 14, the thigh on the thigh connecting pad 16, and the sole on the sole support 19, and then sticks the back sticker on the outside, so that the whole leg is fixed. After adjusting the length of back and forth sliding of the controller 18, the brushless motor 3 is started, the gyro wheel 2 is rotated by the brushless motor 3, and the belt 4 moves back and forth outside the gyro wheel 2. At this time, the sliding block 5 on the upper surface of the belt 4 also moves back and forth inside the slide groove 7 of the shell 6, helping the patient to do the flexion and extension movement. When the lifting leg movement is needed, the bolt at the upper end of the connecting support 9 is loosened, the connecting position of the chuck 10 is exchanged, and then rotated by 180 degrees. After that, the leg rehabilitation training device is stood up, and the above steps are repeated to fix the thigh and calf. Then, the stroke is adjusted again, and the sliding block 5 slides up and down inside the slide groove 7 of the shell 6, so as to help the user to stretch the muscles and tendons when lifting the leg.

[0025] As Figures 1-4As shown, this utility model embodiment provides an implementation method. Based on the above implementation method, the front and back sides of the calf connecting pad 14 and the thigh connecting pad 16 are both made of backing material.

[0026] Analysis of the above structure shows that when replacement or cleaning is needed, simply peel off the backing.

[0027] like Figures 1-4 As shown, this utility model embodiment provides an implementation method. Based on the above implementation method, the outer surface of the lower leg support 11 and the thigh support 13 is covered with an anti-slip pad 21 around the middle section.

[0028] Analysis of the above structure shows that the anti-slip rubber pads 21 that are fitted around the outer surface of the middle section of the calf support 11 and the thigh support 13 can provide a certain friction force for the calf connecting pad 14 and the thigh connecting pad 16, reducing the displacement of the calf connecting pad 14 and the thigh connecting pad 16 during exercise.

[0029] like Figures 1-4 As shown, this utility model embodiment provides an implementation method. Based on the above implementation method, the calf lateral support 11 is inserted and connected to the chuck 10 and the rotating shaft 12, the thigh support 13 is inserted and connected to the rotating shaft 12, a fixed handle 22 is rotatably connected to the upper end of the connection between the calf lateral support 11 and the chuck 10 and the rotating shaft 12, and a fixed handle 22 is also connected to the lower end of the connection between the thigh support 13 and the rotating shaft 12. An anti-slip pad is provided at the end of the fixed handle 22.

[0030] Analysis of the above structure shows that, first, the length of the user's thigh and calf is measured, and the calf outer support 11 and thigh support 13 are inserted and removed inside the chuck 10 and the rotating shaft 12. After adjusting them to be the same length as the thigh and calf, the handle 22 is rotated inward to fix the calf outer support 11 and thigh support 13.

[0031] like Figures 1-4 As shown, this utility model embodiment provides an implementation method in which thigh pads 23 are sleeved on the left ends of the two thigh supports 13.

[0032] Analysis of the above structure shows that the thigh pad 23 is fitted at the ends of the two thigh supports 13, which can prevent the thigh from rubbing against the thigh support 13 when the user places his thigh.

[0033] like Figures 1-3 As shown in the figure, this utility model embodiment provides an implementation method. Based on the above implementation method, the lower end of the connection between the slider 5 and the slide groove 7 is provided with an arc chamfer.

[0034] The arc chamfer at the lower end of the connection between the sliding block 5 and the sliding groove 7 can reduce the friction and prolong the service life.

[0035] As shown in the drawings, the embodiment of the utility model provides an implementation mode, based on the above implementation mode, the controller 18 internally installs a bluetooth signal transmission module. Figures 1-4

[0036] When the internal data needs to be adjusted, the mobile phone, computer and other smart devices can be connected to the controller 18 for connection and control, so that the internal data can be adjusted conveniently.
