[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] For this rehabilitation training auxiliary device, when the patient exercises the leg, by exerting force on the calf to turn up the turning block, the turning block drives the extension tube to turn up through the clamping block, drives the sleeve and the rotating rod to turn in the same direction, and due to the position change at the connection between the turning block and the extension tube, the extension tube is driven to slide inside the sleeve. And when the rotating rod rotates, it will drive the spiral spring to deform, and the elastic force after the deformation of the spiral spring is used to hinder the upward turning of the rotating rod and the turning block, so as to achieve the effect of exercising the patient's calf. And the turning blocks on both sides can operate independently.

Specific implementation manner

[0020] As Figure 1 shown, a rehabilitation training auxiliary device includes a turning cushion 10, the bottom of the turning cushion 10 is fixedly connected with a support base 11, a pair of mirror-symmetrical flipping grooves 20 are opened at the left and right ends of the front side of the turning cushion 10, and the left and right sides inside the flipping grooves 20 are rotatably connected with flipping blocks 21 through movable shafts, and the flipping blocks 21 are used for exercising the legs of patients.

[0021] Preferably, the front surface of the flipping block 21 is an arc design conforming to the human leg, and a Velcro tape 22 is arranged on the front surface of the flipping block 21. When in use, the patient sits on the surface of the turning cushion 10, places the two calves inside the front surface of the flipping block 21, and fixes the calves of the patient inside the flipping block 21 through the Velcro tape 22.

[0022] Specifically, referring to Figure 1 、 2, the left and right sides of the support base 11 are rotatably connected with rotating rods 23. The front sides of the two rotating rods 23 are connected with a sleeve 24, and an extension tube 25 is slidably connected inside the sleeve 24; a pair of clamping blocks 26 are fixedly connected to the rear side of the flipping block 21, and the opposite sides of the pair of clamping blocks 26 are movably connected to the extension tube 25 through a movable shaft; fixing rings 27 are arranged on the outer sides of the two rotating rods 23, the fixing rings 27 are fixedly connected to the surface of the support base 11, a volute spring 28 is arranged inside the fixing rings 27, the outer end of the volute spring 28 is fixedly connected to the fixing ring 27, and the inner part of the volute spring 28 is fixedly connected to the surface of the rotating rod 23.

[0023] When the patient exercises the legs, by exerting force on the calf to flip the flipping block 21 upwards, the flipping block 21 drives the extension tube 25 to flip upwards through the clamping blocks 26, drives the sleeve 24 and the rotating rod 23 to flip in the same direction, and due to the change in the position at the connection between the flipping block 21 and the extension tube 25, the extension tube 25 is driven to slide inside the sleeve 24. And when the rotating rod 23 rotates, it will drive the volute spring 28 to deform, and the elastic force after the deformation of the volute spring 28 is used to hinder the upward flipping of the rotating rod 23 and the flipping block 21, so as to achieve the effect of exercising the patient's calf. And the flipping blocks 21 on both sides can operate independently.

[0024] In order for the device to only exercise the patient's legs, the device will appear too single and cannot meet the needs of exercising other body parts of the patient. Therefore, a hand exercise mechanism is proposed.

[0025] Reference Figure 4 , an adjustable fixing plate 35 is arranged at the top of the turning cushion 10. The left and right sides of the bottom of the fixing plate 35 are respectively fixedly connected with fixing tubes 40. A support spring 41 is fixedly connected inside the fixing tubes 40. The bottom of the support spring 41 is fixedly connected with a pulling tube 42. The opposite sides of the bottoms of the two pulling tubes 42 are fixedly connected with a pull handle 43.

[0026] When in use, the patient can hold the pull handle 43 with the palm of the hand and pull it downwards, driving the pulling tube 42 to slide inside the fixing tube 40, and at the same time deforming and stretching the support spring 41. The elastic force of the deformed support spring 41 hinders the patient from pulling the pull handle 43, and the patient needs to use greater force to counter the elastic force of the support spring 41, so as to achieve the effect of exercising the patient's hand.

[0027] Since the arm lengths and heights of different patients are different, in order to better enable the patient's hand to hold the pull handle 43 in the correct posture, a mechanism for adjusting the height of the fixing plate 35 is proposed.

[0028] Reference Figure 3, an adjustment groove 30 is formed at the rear side of the turning cushion 10. A rotatable threaded rod 31 is rotatably connected to the middle position of the inner bottom of the adjustment groove 30. The top of the threaded rod 31 is threadedly connected to a fixing plate 35. Support blocks 32 are fixedly connected to the left and right sides inside the adjustment groove 30. Guide rods 33 are fixedly connected to the tops of the support blocks 32. The two guide rods 33 are slidably connected to the fixing plate 35.

[0029] Preferably, stoppers 34 are fixedly connected to the tops of the two guide rods 33. The bottom of the stopper 34 is rotatably connected to the threaded rod 31. During use, by rotating the threaded rod 31, the fixing plate 35 is driven to slide up or down along the guide rod 33, so as to achieve the effect of adjusting the height of the fixing plate 35. The stopper 34 can prevent the fixing plate 35 from disconnecting from the threaded rod 31 during movement.

[0030] Furthermore, a driven bevel gear 36 is fixedly connected to the bottom surface of the threaded rod 31. A driving bevel gear 37 is engaged with the right side of the driven bevel gear 36. A turning rod 38 is fixedly connected to the right side of the driving bevel gear 37. The turning rod 38 is rotatably connected to the surface of the turning cushion 10. During use, the patient only needs to rotate the turning rod 38 on the right side of the turning cushion 10, and the threaded rod 31 can be driven to rotate through the cooperation of the driving bevel gear 37 and the driven bevel gear 36, so as to achieve the effect of adjusting the position of the fixing plate 35. Moreover, the patient can sit on the turning cushion 10 to adjust the position of the fixing plate 35.

[0031] Reference Figure 1 , a fixing piece 50 is fixedly connected to the left side of the turning cushion 10. A bolt (not shown in the figure) is threadedly connected to the fixing piece 50. A positioning ring 51 is fixedly connected to the left end of the turning rod 38. The outer side of the positioning ring 51 is a regular polygon. When the position of the fixing plate 35 is adjusted, the bolt on the fixing piece 50 is rotated to gradually approach the surface of the positioning ring 51 until the bolt fits against one side surface of the positioning ring 51, so as to achieve the effect of fixing the turning rod 38, and further achieve the effect of positioning the fixing plate 35.

[0032] The working principle of the present utility model is as follows: When the patient exercises the legs, the turning block 21 is turned upward by the force of the calf. The turning block 21 drives the extension tube 25 to turn upward through the clamping block 26, drives the sleeve 24 and the rotating rod 23 to turn in the same direction, and due to the change in the position at the connection between the turning block 21 and the extension tube 25, the extension tube 25 is driven to slide inside the sleeve 24. And when the rotating rod 23 rotates, the spiral spring 28 will be deformed. The elastic force after the deformation of the spiral spring 28 is used to hinder the upward turning of the rotating rod 23 and the turning block 21, so as to achieve the effect of exercising the patient's calf. And the turning blocks 21 on both sides can operate independently.

[0033] The foregoing has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above-mentioned embodiments, and what is described in the above-mentioned embodiments and the specification only illustrates the principles of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and all these changes and improvements fall within the scope of the present utility model claimed.
