The transmission assembly comprises an annular belt part which can move along the annular direction thereof. The first roller assembly comprises a first roller which can rotate along the axis thereof. The outer wall of the first roller abuts against the belt part so that the belt part is subjected to resistance when moving. The support body assembly comprises a first support body which is hingedly connected and provided with a damping assembly. The damping assembly comprises a first rod part on one side of the hinged joint and a second rod part on the other side of the hinged joint.

The second rod part is fixedly connected with a damping rod which is correspondingly arranged with the first roller assembly. The first support body is connected with a connecting frame. The first rod part passes through the connecting frame. The connecting frame is fixedly provided with a handle. When the damping assembly is in a free state, the damping rod abuts against the outer wall of the first roller, and the first rod part is in a separated state from the handle. When the first rod part and the handle are driven to approach each other, the first rod part rotates along the hinged joint to make the second rod part rotate, so that the damping rod gradually separates from the outer wall of the first roller.

[0005] Further, the damping rod comprises a damping surface which can be attached to the outer wall of the first roller.

[0006] Further, the outer wall of the first roller is provided with a damping layer.

[0007] Further, the damping surface is a circular arc surface which is matched with the outer wall of the damping layer.

[0008] Further, a plurality of first roller assemblies are arranged along the annular moving direction of the belt part, and the axial direction of the first roller assembly is perpendicular to the annular moving direction of the belt part.

[0009] Further, the connecting frame comprises an extension frame provided with a second slot body, the first rod part passes through the second slot body, the extension frame is provided with an elastic assembly, the elastic assembly comprises a second insertion rod, the second insertion rod is inserted into the second slot body, the second insertion rod abuts against the side of the first rod part away from the handle, the side of the second insertion rod away from the abutting side of the first rod part is provided with a spring, the side of the spring away from the abutting side of the second insertion rod is provided with a first insertion rod, and the first insertion rod is threadedly connected and inserted into the extension frame.

[0010] Further, the damping rod length direction is parallel to the first roller assembly axial direction.

[0011] Further, the second rod part is connected with a connecting rod, the connecting rod is connected with a connecting block, and the connecting block is connected with the damping rod.

[0012] Further, the connecting block is located at both ends of the damping rod length direction.

[0013] Further, the support body assembly further comprises a third support body, the upper end of the third support body is provided with an opening part, and the upper belt-shaped part is located at the opening part.

[0014] The present application has the following beneficial effects:

[0015] When the user steps on the belt-shaped part and drags the belt-shaped part to move in a ring shape by relying on the static friction force of the shoe sole, the user holds the first rod part and the handle tightly with both hands to keep the body balanced, when the user's body loses balance and both hands release the first rod part and the handle, the damping assembly rotates clockwise along the hinge point, so that the damping rod abuts against the outer wall surface of the damping layer, thereby limiting the rotation of the damping layer, and then the speed of the ring-shaped movement of the belt-shaped part can be reduced, the belt-shaped part can be quickly decelerated and stopped, and the safety of the training device is improved.

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments will be described clearly and completely below in combination with the drawings in the embodiments. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0026] As Figure 1 shown, a rehabilitation exercise training device for preventing sarcopenia includes a support body assembly 1, a first roller assembly 4, and a transmission assembly 6. As Figure 1 , Figure 3 shown, the support body assembly 1 includes a third support body 14, which is a frame structure, Figure 3 wherein the third support body 14 circumferentially forms an enclosing structure, and the third support body 14 includes support plates 141 located on the upper and lower sides in the orientation shown. Figure 3 wherein the third support body 14 is a side wall plate of the third support body 14. Figure 1 wherein the bottom of the third support body 14 is closed and the top is provided with an opening part 142.

[0027] As Figure 3 shown, the upper end of the upper support plate 141 and the lower end of the lower support plate 141 are respectively connected and fixed with a second support body 12, and the second support body 12 is provided with a first groove body 121, so that the second support body 12 forms a notch on the side close to the support plate 141.

[0028] As Figure 1As shown, the first support body 11 is connected to the left side of the second support body 12, and the first support body 11 extends upward, and the first support body 11 is fixedly connected or integrally formed with the second support body 12.

[0029] As shown in Figure 1 , Figure 5 , a connecting frame 13 is fixedly installed between the upper parts of the two first support bodies 11, Figure 5 , the connecting frame 13 includes extension frames 131 at the upper and lower ends, and the extension frames 131 are provided with second groove bodies 1311, as shown in Figure 6 , the second groove bodies 1311 extend through the extension frames 131. A handle 5 is inserted and installed at the left end of the second groove body 1311, and the upper end of the handle 5 extends out of the second groove body 1311. The second groove body 1311 is an elongated slot, and the length of the second groove body 1311 is greater than the maximum outer diameter of the part inserted into the second groove body 1311.

[0030] As shown in Figure 1 , the transmission assembly 6 includes a second roller assembly 61 and a third roller assembly 63, which are arranged on the left and right sides, respectively. The second roller assembly 61 includes a second main shaft 611, and the outer wall of the second main shaft 611 is sleeved with a second roller 612, which can roll along the outer wall of the second main shaft 611. The third roller assembly 63 includes a third main shaft 631, and the outer wall of the third main shaft 631 is sleeved with a third roller 632, which can roll along the outer wall of the third main shaft 631.

[0031] As shown in Figure 3 , the second main shaft 611 and the third main shaft 631 are respectively inserted into the two side support plates 141 and fixed, and the second roller 612 and the third roller 632 are respectively located between the two side support plates 141.

[0032] As shown in Figure 1 , the second roller 612 and the third roller 632 are sleeved with an annular belt-shaped component 62 between the outer walls of the second roller 612 and the third roller 632, and the belt-shaped component 62 is connected to the second roller 612 and the third roller 632. Figure 5 The belt-shaped component 62 is a relatively wide belt-shaped structure, and its length direction is annular. As shown in Figure 1 , the second roller 612 and the third roller 632 are located inside the annular part of the belt-shaped component 62, and the second roller 612 and the third roller 632 stretch the belt-shaped component 62 left and right. The upper belt-shaped component 62 is located at the opening part 142 of the third support body 14, and the upper belt-shaped component 62 is stepped on to drive the annular movement of the belt-shaped component 62, which in turn drives the rotation of the second roller 612 and the third roller 632. The annular movement of the belt-shaped component 62 is resisted by the second roller 612 and the third roller 632, preventing the belt-shaped component 62 from moving too fast and reducing the risk of accidents.

[0033] As shown in Figure 1The strip-shaped part 62 is supported at the bottom when stepped on, and the bottom of the strip-shaped part 62 above is in abutment with the first roller assembly 4. The first roller assembly 4 is provided with a plurality of first rollers 42 arranged along the annular movement direction of the strip-shaped part 62, and the axis of the first roller assembly 4 is perpendicular to the annular movement direction of the strip-shaped part 62.

[0034] Specifically, the first roller assembly 4 includes a first main shaft 41, and the outer wall of the first main shaft 41 is sleeved with the first roller 42 which can rotate along its own axis. Figure 3 As shown in the figure, the two ends of the first main shaft 41 are respectively inserted into the two side support plates 141, and the first roller 42 is located between the two side support plates 141. Figure 3 In the figure, the first roller 42 and the first main shaft 41 are drawn in cross-section only for identification. As shown in the figure, Figure 2 As shown in the figure, the outer wall of the first roller 42 is sleeved with a damping layer 43 which wraps the circumferential outer wall of the first roller 42. The damping layer 43 is made of rubber material, and the upper end of the damping layer 43 abuts and tightly presses the strip-shaped part 62 upwards, so that the strip-shaped part 62 is subjected to resistance when moving.

[0035] As shown in the figure, Figure 1 As shown in the figure, the first support body 11 is hingedly connected with the damping assembly 3 which includes a first rod portion 31 located on one side of the hinge point (towards the upward direction) and a second rod portion 32 located on the other side of the hinge point (towards the lower right direction). The first rod portion 31 and the second rod portion 32 can rotate synchronously along the hinge point, and the hinge point is located to the left of the leftmost first roller assembly 4. The first rod portion 31 and the second rod portion 32 form an obtuse angle α.

[0036] As shown in the figure, Figure 1 As shown in the figure, the second rod portion 32 extends to the lower right along the hinge point and is fixedly connected with a connecting rod 33 at the extension end. The length direction of the connecting rod 33 is arranged along the distribution direction of the plurality of first roller assemblies 4. Figure 3 As shown in the figure, the connecting rod 33 is located in the first groove body 121.

[0037] As shown in the figure, Figure 1 As shown in the figure, Figure 3 , Figure 4 As shown in the figure, a damping rod 35 is installed between the two side support plates 141. The length direction of the damping rod 35 passes through the support plate 141 and is connected with the connecting block 34 at both ends. The damping rod 35 is arranged one by one corresponding to the first roller assembly 4, and the damping rod 35 is located to the right of the corresponding first roller assembly 4. Figure 3 In the figure, the cross-sectional line of the damping rod 35 is only for identification. When the second rod portion 32 rotates along the hinge point, the damping rod 35 rotates synchronously. Since the damping rod 35 passes through the support plate 141, the support plate 141 is correspondingly provided with an arc-shaped groove.

[0038] AsFigure 2 , Figure 3 As shown, the length direction of the damping rod 35 is parallel to the axial direction of the first roller assembly 4. The damping rod 35 includes a damping surface 351, which is an arc surface that matches the outer wall surface of the damping layer 43.

[0039] like Figure 6 As shown, the first rod portion 31 extends upward through the second groove 1311. (As indicated...) Figure 7 , Figure 8 As shown, since the first rod 31 extends upward and the connecting rod 33 connected to the second rod 32 extends to the right, the damping assembly 3 as a whole tends to rotate clockwise. Therefore, when the damping assembly 3 is in a free state, the damping rod 35 abuts against the outer wall of the first roller 42 (actually the outer wall of the damping layer 43), and the damping surface 351 is in contact with the outer wall of the first roller 42 (actually the outer wall of the damping layer 43). At this time, the first rod 31 and the handle 5 are separated to the left and right.

[0040] like Figure 1 , Figure 2 As shown, when the user stands on the top of the belt component 62 and simultaneously holds the first rod 31 and the handle 5 for limb support, holding the first rod 31 and the handle 5 drives the first rod 31 and the handle 5 to move closer to each other. The first rod 31 rotates along the hinge point to make the second rod 32 rotate, thereby causing the damping rod 35 to gradually separate from the outer wall of the first roller 42.

[0041] When the user steps on the belt component 62, the static friction of the sole of the shoe drags the belt component 62 in a circular motion. The user holds the first rod 31 and the handle 5 with both hands to maintain body balance. When the user loses balance and releases the first rod 31 and the handle 5, the damping component 3 rotates clockwise along the hinge point so that the damping rod 35 abuts against the outer wall of the damping layer 43, thereby restricting the rotation of the damping layer 43 and reducing the circular movement speed of the belt component 62. The belt component 62 can quickly decelerate and stop, thereby improving the safety of using the training device.

[0042] like Figure 5As shown, the extension frame 131 is provided with the elastic assembly 2, the elastic assembly 2 comprises the second insertion rod 23, the second insertion rod 23 is inserted into the second slot body 1311 from the right side of the extension frame 131, the second insertion rod 23 can move left and right along the inner wall of the extension frame 131, and the second insertion rod 23 is at least partially located in the extension frame 131. The second insertion rod 23 abuts against the first rod part 31 away from the handle 5, the second insertion rod 23 abuts against the spring 22 away from the side of the first rod part 31, the spring 22 abuts against the first insertion rod 21 away from the side of the second insertion rod 23, the first insertion rod 21 is screwed and inserted into the extension frame 131, and the right side of the first insertion rod 21 extends out of the right side of the extension frame 131. By arranging the elastic assembly 2, auxiliary power is provided for the user to hold the first rod part 31 and the handle 5 and drive the first rod part 31 and the handle 5 to approach each other, so as to facilitate the user to hold the first rod part 31 and the handle 5. The arrangement of the elastic assembly 2 does not affect the abutment between the damping rod 35 of the damping assembly 3 and the outer wall surface of the damping layer 43, and according to the depth of the first insertion rod 21 inserted into the extension frame 131, the force between the damping rod 35 and the damping layer 43 when they abut against each other in the free state can be adjusted to meet the experience needs of different users.

Any technical scheme falling within the concept of the present application shall fall within the protection scope of the present application. It should be noted that, for ordinary skilled in the art, some improvements and decorations without departing from the principles of the present application shall also be considered as the protection scope of the present application.
