The mounting assembly includes a mounting shaft 1, to which the support rod 1 and support rod 2 are rotatably connected. Mounting grooves are formed on the side walls of both the guard plate and the base plate. The mounting shaft 1 is inserted into the mounting groove. An annular limiting groove is formed in the middle of the inner wall of the mounting groove. Symmetrical through grooves are formed on the upper and lower sides of the end of the mounting shaft 1 located inside the mounting groove.

[0009] Furthermore, the end of the limiting rod located inside the movable groove is configured as a round head.

[0010] Furthermore, both platform one and platform two have an arc-shaped groove in the middle, and the arc-shaped groove is adapted to the round end of the limiting rod.

[0011] Furthermore, the distance between the two arc-shaped grooves is greater than the depth of the slot.

[0012] Furthermore, the edges of the guard plate and the base plate are provided with mounting holes for installing straps.

[0013] The beneficial effects of the foot and ankle injury support and assistive walking device of the present invention are as follows:

[0014] 1. By setting up support components, the protective plate and the base plate can be supported. When in use, the movable column is inserted into the central through hole of the mounting ring and the connecting ring. At this time, the end of the limiting rod abuts against the middle of the platform. The platform pushes the limiting rods on both sides to move outward, and the spring is compressed, so that the other end of the limiting rod is inserted into the limiting hole opened on the opposite side of the support rod 1 and the support rod 2. This makes the support rod 1, the support rod 2 and the mounting ring connected together as a whole. This allows the protective plate, the base plate, the support rod 1, the support rod 2 and the mounting ring to form a triangular structure, so that the protective plate and the base plate can be fixed in a vertical position. This is convenient for protecting the ankle during walking training and avoiding secondary injuries. Furthermore, by pulling the movable column outward, the second platform inside the movable groove moves to align with the limiting rod. Under the push of the first spring, the end of the limiting rod abuts against the surface of the second platform. At this time, the other end of the limiting rod disengages from the limiting hole. At this time, the first support rod, the second support rod, and the mounting ring can move relative to each other. Then, the toes can be slowly flexed upward, making the angle between the guard plate and the bottom plate smaller. The first support rod and the second support rod drive the internal torsion spring to rotate and store force through the first and second side plates respectively. At this time, the angle between the first support rod and the second support rod becomes smaller. When the ankle position is not stressed, the torsion spring causes the first support rod and the second support rod to return to the same straight line. By repeatedly flexing the toes in this way, the rehabilitation exercise of the ankle can be further carried out.

[0015] 2. By setting a limiting component, the movement of the guard plate and base plate is further restricted. During use, the bolt and threaded hole are used to fully insert the moving rod into the sliding hole two, while the locking block is inserted into the slot, thereby restricting the rotation of connecting rod one and connecting rod two. This allows the movable column to be stably inserted into the central through hole of the mounting ring. The locking block and slot are used to fix connecting plate two and mounting shaft two together, preventing connecting plate one and connecting plate two from rotating and further restricting the movement of the guard plate and base plate. When ankle exercise is required, the bolt is unscrewed outward, and the bolt disengages from the threaded hole. Then, connecting rod one and connecting rod two are pulled outward, and connecting rod two pulls the movable column outward, allowing support rod one and support rod two to move. Connecting rod one pulls the moving rod, which in turn causes the locking block to disengage from the slot. This allows connecting plate two and mounting shaft two to rotate around mounting shaft two, thus moving the guard plate and base plate two, enabling rehabilitation exercises for the ankle.

[0016] 3. The installation components facilitate the disassembly and assembly of the support components. During use, pressing the push block inward causes the push block to move the push plate, so that the end of the push plate abuts against the inclined surface of the inclined groove. This, in turn, forces the limiting block to move into the through groove, retracting the limiting block into the through groove. This makes it easy to rotate the mounting shaft into or remove it from the mounting groove. The spring four pushes the slider two and the limiting block to reset, so that the end of the limiting block is inserted into the annular limiting groove. This allows the mounting shaft one to be rotated and installed in the mounting groove, which facilitates the disassembly and assembly of the support components and the limiting components for maintenance.

[0025] The present invention will be described in detail below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in the present application can be combined with each other.

[0026] like Figures 1-6 According to one aspect of the present invention, a foot and ankle injury support and assistive walking device is provided, comprising a protective plate 1 and a base plate 2. The cross-section of both the protective plate 1 and the base plate 2 is U-shaped. The protective plate 1 is vertical and even directly above one end of the base plate 2. Connecting plates 1 and 7 are fixedly connected to the bottom two sides of the protective plate 1, and connecting plates 2 and 8 are symmetrically fixedly connected to the side walls of the ends of the base plate 2. A mounting shaft 2 and 9 are fixedly connected to the outer side wall of the connecting plate 1 and 7. The connecting plates 2 and 8 are rotatably mounted on the mounting shaft 2 and 9. Support components 3 are provided on the sides of the protective plate 1 and the base plate 2 to support and restrict the position of the protective plate 1 and the base plate 2. A limiting component 4 is provided on the mounting shaft 2 and 9 to restrict the position of the connecting plates 1 and 7 and the connecting plates 2 and 8. In operation, the device is worn on the injured foot and ankle of the patient by a strap. The position of the protective plate 1 and the base plate 2 is fixed by the support component 3 and the limiting component 4, which facilitates the protection of the injured foot and ankle of the patient by the cooperation of the protective plate 1 and the base plate 2. When used with crutches, it facilitates the patient's walking rehabilitation training.

[0027] In this embodiment, the support assembly 3 includes a first support rod 31 and a second support rod 33. One end of the first support rod 31 is rotatably connected to the middle position of the outer side wall of the slide plate, and the edge of the other end of the first support rod 31 is fixedly connected to a first side plate 32. One end of the second support rod 33 is rotatably connected to the middle position of the outer side wall of the base plate 2, and the edge of the other end of the second support rod 33 is fixedly connected to a second side plate 34. The first side plate 32 and the second side plate 34 are arranged opposite to each other. A mounting ring 35 is provided in the middle position of the first side plate 32 and the second side plate 34. Connecting rings 38 are fixedly connected to both sides of the mounting ring 35. Mounting cavities 37 are respectively opened in the middle of the inner side walls of the first side plate 32 and the second side plate 34. The connecting rings 38 on both sides extend to the mounting cavities on the first side plate 32 and the second side plate 34, respectively. In section 37, the connecting ring 38 is rotatably connected to the inner wall of the mounting cavity 37 on both sides. Torsion springs 39 are fixedly installed between the connecting rings 38 and the inner wall of the mounting cavity 37. Receiving cavities 310 are opened on both sides of the mounting ring 35 corresponding to support rod 1 31 and support rod 2 33. The two ends of the receiving cavities 310 are open. Limiting rods 311 are slidably installed inside the receiving cavities 310. A fixing plate 312 is fixedly connected to the middle of the limiting rod 311. A spring 314 is fixedly installed between the side of the fixing plate 312 away from the center of the mounting ring 35 and the inner wall of the receiving cavity 310. One end of the limiting rod 311 extends through to the outside of the mounting ring 35, and the other end extends into the central through hole of the mounting ring 35. Support rod 1 31 and support rod 2... A limiting hole 313 is provided in the middle of the end of the mounting ring 35 adjacent to the mounting ring 33. The limiting rod 311 is adapted to the limiting hole 313. The central through holes of the mounting ring 35 and the connecting ring 38 are the same size, and a movable column 36 is movably installed in the middle of the central through hole. One end of the movable column 36 extends to the outside of the side plate 32. The movable column 36 has symmetrical movable grooves 315 on one end near the side plate 34. The movable grooves 315 on both sides are adapted to the limiting rod 311, and the end of the limiting rod 311 is slidably disposed in the movable groove 315. Platform 316 and platform 317 are sequentially provided on the inner wall of the movable groove 315 from the side plate 32 toward the side plate 34. Platform 317 is closer to the center of the movable column 36. In operation, in the initial state, the movable column 316... 6. Inserted into the central through hole of mounting ring 35 and connecting ring 38, the end of limiting rod 311 abuts against the middle of platform 1 316. Platform 1 316 pushes the limiting rods 311 on both sides to move outward, compressing spring 1 314. This allows the other end of limiting rod 311 to be inserted into the limiting hole 313 opened on the opposite side of support rod 1 31 and support rod 2 33, thus connecting support rod 1 31, support rod 2 33 and mounting ring 35 together as a whole. This allows the guard plate 1, base plate 2, support rod 1 31, support rod 2 33 and mounting ring 35 to form a triangular structure, thereby fixing the guard plate 1 and base plate 2 in a vertical position, which facilitates ankle protection during walking training.To avoid secondary injury; furthermore, by pulling the movable column 36 outward, the platform 317 inside the movable groove 315 moves to align with the limiting rod 311. Under the push of the spring 314, the end of the limiting rod 311 abuts against the surface of the platform 317. At this time, the other end of the limiting rod 311 disengages from the limiting hole 313. At this time, the support rod 31, the support rod 33, and the mounting ring 35 can move relative to each other. Then, the toes can be slowly flexed upward, making the angle between the guard plate 1 and the base plate 2 smaller. The support rod 31 and the support rod 33 drive the internal torsion spring 39 to rotate and store force through the side plate 32 and the side plate 34 respectively. At this time, the angle between the support rod 31 and the support rod 33 becomes smaller. When the ankle position is not stressed, the torsion spring 39 resets the support rod 31 and the support rod 33 to the same straight line. By repeatedly flexing the toes in this way, further rehabilitation exercises for the ankle can be performed.

[0028] In this embodiment, the limiting component 4 includes a movable rod 49. A sliding hole 46 is provided in the middle of the mounting shaft 9, extending inward into the connecting plate 7. A threaded hole 44 is provided at the end of the sliding hole 46 away from the connecting plate 8. The movable rod 49 is slidably disposed inside the sliding hole 46, and the end of the movable rod 49 extends to the outside of the mounting shaft 9. A connecting rod 41 is fixedly connected to the end of the movable rod 49 located on the mounting shaft 9. A sliding cavity 410 is provided inside the end of the connecting rod 41 away from the movable rod 49. A connecting rod 42 is slidably installed in the sliding cavity 410. 10 has a spring 411 internally fixed to reset the connecting rod 42. The end of the connecting rod 42 away from the connecting rod 41 is fixedly connected to the movable column 36. A through sliding hole 45 is opened in the middle of the movable rod, and a bolt 43 is movably installed in the sliding hole 45. The bolt 43 and the threaded hole 44 are compatible. A groove 47 is opened on the outer wall of the mounting shaft 9 away from the connecting plate 7 and adjacent to the connecting plate 8. A locking block 48 is fixedly connected to the outer wall of the movable rod. The locking block 48 and the groove 47 are compatible. During operation, the moving rod 49 is fully inserted by the cooperation of the bolt 43 and the threaded hole 44. The sliding hole 46 is inserted into the sliding block 48, which is simultaneously inserted into the slot 47. This restricts the rotation of connecting rod 1 41 and connecting rod 2 42, thereby ensuring that the movable column 36 is stably inserted into the central through hole of the mounting ring 35. Through the cooperation of the locking block 48 and the slot 47, the connecting plate 2 8 and the mounting shaft 2 9 are fixed together, preventing the connecting plate 1 7 and connecting plate 2 8 from rotating. This further restricts the movement of the guard plate 1 and the base plate 2. When ankle exercise is required, the bolt 43 is unscrewed outward, disengaging from the threaded hole 44. Then, the connecting rod 1 41 and connecting rod 2 42 are pulled outward. Connecting rod 42 pulls the movable column 36 outward, which allows support rod 31 and support rod 33 to pull the moving rod 49 via connecting rod 41. This causes the locking block 48 to disengage from the locking groove 47, allowing connecting plate 8 and mounting shaft 9 to rotate around mounting shaft 9. This allows the protective plate 1 and base plate 2 to move, enabling rehabilitation exercises for the ankle. During the exercise, when support rod 31, support rod 33 and mounting ring 35 move, they can pull connecting rod 42 along the sliding cavity 410.

[0029] In this embodiment, mounting components 5 are provided at opposite ends of support rod 1 31 and support rod 2 33. The mounting components 5 rotatably connect support rod 1 31 and support rod 2 33 to the guard plate 1 and the base plate 2, respectively. The mounting components 5 include a mounting shaft 51, to which support rod 1 31 and support rod 2 33 are rotatably connected. Mounting grooves 514 are provided on the side walls of the guard plate 1 and the base plate 2. Mounting shaft 51 is inserted into the mounting groove 514. An annular limiting groove 515 is provided in the middle of the inner wall of the mounting groove 514. 51 has symmetrical through grooves 57 on both the upper and lower sides of its end inside the mounting groove 514. A limit block 58 is slidably installed in the through groove 57. A second sliding groove 511 is formed on the inner wall of the through groove 57. A second slider 513 is fixedly connected to the side wall of the limit block 58 and is slidably disposed in the second sliding groove 511. A fourth spring 512 is fixedly installed in the second sliding groove 511 to reset the second slider 513. A second sliding cavity 56 is formed in the middle of the end of the mounting shaft 51 located outside the mounting groove 514. A push block 52 is slidably installed in the second sliding cavity 56. The inner walls of the upper and lower sides are provided with sliding grooves 53. A slider 54 is fixedly connected to the side wall of the push block 52 corresponding to the sliding groove 53. The slider 54 is slidably disposed in the sliding groove 53. A spring 55 is fixedly installed in the sliding groove 53 to reset the slider 54. A push plate 510 is fixedly connected to the edge of the push block 52 near the limiting block 58. An inclined groove 59 is provided at the middle of the end of the limiting block 58 inside the through groove 57. The top of the push plate 510 is adjacent to the top of the inclined groove 59. During operation, by pressing the push block 52 inward, the push block 52 drives the push plate 510. The movement causes the end of the push plate 510 to abut against the inclined surface of the inclined groove 59, thereby pressing the limiting block 58 to move into the through groove 57, retracting the limiting block 58 into the through groove 57, making it easier to rotate the mounting shaft 51 into or out of the mounting groove 514. The spring 4 512 pushes the slider 2 513 and the limiting block 58 to reset, so that the end of the limiting block 58 is inserted into the annular limiting groove 515, thereby allowing the mounting shaft 51 to be rotated and installed in the mounting groove 514. This facilitates the disassembly and assembly of the support assembly 3 and the limiting assembly 4 for maintenance.

[0030] In this embodiment, the end of the limiting rod 311 located inside the movable groove 315 is set to a round head shape, which facilitates the end of the limiting rod 311 to slide along the surfaces of platform one 316 and platform two 317 during operation.

[0031] In this embodiment, an arc-shaped groove 318 is provided in the middle of both platform 1 316 and platform 2 317. The arc-shaped groove 318 is adapted to the round end of the limiting rod 311. During operation, the end of the limiting rod 311 is engaged in the arc-shaped groove 318, so that the limiting rod 311 will not move easily.

[0032] In this embodiment, the distance between the two arc-shaped grooves 318 is greater than the depth of the slot 47. During operation, when the end of the limiting rod 311 moves from the platform one 316 to the platform two 317, the locking block 48 can completely disengage from the slot 47, thus not blocking the rotation of the connecting rod one 41 and the connecting rod two 42.

[0033] In this embodiment, mounting holes 6 for installing straps are provided on the edges of the protective plate 1 and the base plate 2. During operation, the straps with Velcro are installed in the mounting holes 6 to facilitate fixing the device to the patient's ankle.

[0034] The working principle of this device is as follows: During operation, the device is worn on the injured ankle of the patient via a strap. The positions of the protective plate 1 and the base plate 2 are fixed by the support component 3 and the limiting component 4, facilitating the protection of the injured ankle by the protective plate 1 and the base plate 2, thereby facilitating the patient's walking rehabilitation training. In the initial state, the movable column 36 is inserted into the central through hole of the mounting ring 35 and the connecting ring 38. At this time, the end of the limiting rod 311 abuts against the middle of the platform 316. The platform 316 pushes the limiting rods 311 on both sides to move outward. Spring 3... 14 is compressed, so that the other end of the limiting rod 311 is inserted into the limiting hole 313 opened on the opposite side of the support rod 1 31 and the support rod 2 33, so that the support rod 1 31, the support rod 2 33 and the mounting ring 35 are connected together to form a whole. This allows the guard plate 1, the base plate 2, the support rod 1 31, the support rod 2 33 and the mounting ring 35 to form a triangular structure, so that the guard plate 1 and the base plate 2 can be fixed in a vertical position. This is convenient for protecting the ankle during walking training and avoiding secondary injury.The bolt 43 and threaded hole 44 engage to fully insert the moving rod 49 into the sliding hole 46, while the locking block 48 engages in the slot 47, thus restricting the rotation of connecting rod 41 and connecting rod 42. This allows the movable column 36 to be stably inserted into the central through hole of the mounting ring 35. The locking block 48 and slot 47 also engage to fix the connecting plate 7 and mounting shaft 9 together, preventing rotation of the connecting plate 7 and connecting plate 8, further restricting the movement of the guard plate 1 and... When the base plate 2 moves, and ankle exercises are required, the bolt 43 is unscrewed outward, disengaging from the threaded hole 44. Then, connecting rod 1 41 and connecting rod 2 42 are pulled outward, causing the movable column 36 to move outward via connecting rod 2 42. This allows support rod 1 31 and support rod 2 33 to move, and connecting rod 1 41 to pull the moving rod 49, thereby disengaging the locking block 48 from the locking groove 47. This allows connecting plate 2 8 and mounting shaft 2 9 to be connected. Connecting plate 2 8 can then surround... Rotating around the mounting shaft 29 allows the movable guard plate 1 and base plate 2 to be moved, enabling rehabilitation exercises for the ankle. When the movable column 36 is pulled outward, the platform 2 317 inside the movable groove 315 moves to align with the limiting rod 311. Under the push of the spring 1 314, the end of the limiting rod 311 abuts against the surface of the platform 2 317. At this time, the other end of the limiting rod 311 disengages from the limiting hole 313. At this point, the support rod 1 31, the support rod 2 33, and the mounting ring 35 can move relative to each other. You can slowly flex your toes upwards, which reduces the angle between the protective plate 1 and the base plate 2. The support rod 1 31 and support rod 2 33 drive the internal torsion spring 39 to rotate and store force through the side plate 1 32 and side plate 2 34 respectively. At this time, the angle between support rod 1 31 and support rod 2 33 becomes smaller. When the ankle position is not stressed, the torsion spring 39 causes support rod 1 31 and support rod 2 33 to return to their original positions and back to the same straight line. By repeatedly flexing your toes in this way, you can further rehabilitate your ankle. Furthermore, by pressing the push block 52 inward, the push block 52 drives the push plate 510 to move, causing the end of the push plate 510 to abut against the inclined surface of the inclined groove 59. This, in turn, forces the limiting block 58 to move into the through groove 57, retracting the limiting block 58 into the through groove 57. This facilitates the rotation of the mounting shaft 51 into or out of the mounting groove 514. The spring 4 512 then pushes the slider 2 513 and the limiting block 58 back to their original positions, causing the end of the limiting block 58 to insert into the annular limiting groove 515. This allows the mounting shaft 51 to be rotatably installed in the mounting groove 514, facilitating the disassembly and assembly of the support assembly 3 and the limiting assembly 4 for maintenance.
