Description

Technical Field

[0001] This invention relates to the field of walking cart technology, specifically a walking cart for leg rehabilitation training. Background Technology

[0002] Currently, rehabilitation training is necessary after hip or knee replacement surgery, leg fractures, arthritis, ligament injuries, ankle sprains, and other conditions. This training can accelerate tissue healing, reduce local swelling, reduce muscle atrophy, promote joint function recovery, prevent osteoporosis, and help patients regain normal work and life abilities as soon as possible. To prevent adverse consequences such as muscle atrophy, intra-articular adhesions, or ligament degeneration and loss of elasticity, functional exercises are also required. Assistive rehabilitation walking devices include crutches and walking aids.

[0003] When using the rehabilitation training cart, a family member must accompany the patient on their first walk to prevent falls. The patient should sit for a while before trying to walk. If no discomfort or dizziness occurs, they can walk further.

Detailed Implementation

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Please see Figure 1-13 The present invention provides a technical solution:

[0035] Example 1,

[0036] A leg rehabilitation training walking cart includes: a training cart 1; a training mechanism 2 located on the back of the training cart 1, capable of performing rehabilitation exercises; and an adjustment mechanism 3 located on the side of the training mechanism 2 near the training cart 1, capable of adjusting the training mechanism 2. This invention allows patients to sit down and rest by flipping the training board 24 using the adjustment mechanism 3 when they need to rest while using the rehabilitation training walking cart. The height of the training board 24 can be adjusted using the adjustment mechanism 3. When not using the training cart, leg muscles can be exercised through the training mechanism 2. Assisted and weight-bearing exercises can be performed according to the patient's actual condition. It is very convenient to use and has a wide range of functions.

[0037] The adjustment mechanism 3 includes tube frames 31 fixedly connected to both sides inside the training vehicle 1. Each tube frame 31 is a hollow frame. Multiple through holes 32 are opened on one side of the tube frame 31. A sliding tube 33 is slidably connected to the outer periphery of each tube frame 31. Sliding grooves 34 are opened on the upper and lower sides of the outer wall of the sliding tube 33. The tube frame 31 is located inside the handrails on both sides of the training vehicle 1. The tube frame 31 is fixedly connected to the handrails of the training vehicle 1. The hollowness inside the tube frame 31 facilitates the fixing of the sliding tube 33. The opening of multiple through holes 32 allows the sliding tube 33 to be adjusted to different heights.

[0038] The slide tube 33 has a locking member 5 inside that can engage with the through hole 32. The locking member 5 includes a locking groove 51 located on the side of the slide tube 33 near the tube support 31, the locking groove 51 corresponding to the position of the through hole 32, a locking rod 52 fixedly connected to the inner wall of the locking groove 51, and a locking arm 53 rotatably connected to the periphery of the locking rod 52, the locking arm 53 being able to engage with the through hole 32. A locking post 54 is fixedly connected to the outer wall of the slide tube 33 at a position corresponding to the locking rod 52. A lever plate 55 is rotatably connected to the periphery of the locking post 54. A locking hole 56 is formed on the periphery of the locking post 54 in the sliding tube 33. The locking arm 53 and the lever plate 55 are fixedly connected by a connecting rod 57. The connecting rod 57 is located within the locking hole 56 and slidably connected to it. The locking hole 56 is arc-shaped. When the connecting rod 57 slides within the locking hole 56, it moves in an arc. When adjusting the height of the sliding tube 33, the lever plate 55 is rotated. 5 is rotatably connected to the locking post 54 on the outer wall of the slide tube 33, and the locking post 54 is coaxial with the locking rod 52 inside the slide tube 33. The actuating plate 55 and the locking arm 53 are fixedly connected by a connecting rod 57. When the actuating plate 55 rotates, the locking arm 53 rotates outside the locking rod 52 inside the slide tube 33. The actuating plate 55 and the locking arm 53 rotate synchronously, and the locking arm 53 can engage with the through hole 32 opened in the tube support 31. When engaging through holes 32 at different heights, the height of the slide tube 33 is different. Furthermore, since the engaging hole 56 of the slide tube 33 is arc-shaped, the connecting rod 57 can only move in an arc within the engaging hole 56. The engaging hole 56 restricts the engaging arm 53 to only engage or open with the through hole 32. Moreover, due to its own weight, the actuating plate 55 will automatically engage with the through hole 32 without external force. The engaging arm 53 protects the slide tube 33.

[0039] The sliding groove 34 contains a rotating component 4. The rotating component 4 includes an upper connecting rod 41 and a lower connecting rod 42 slidably connected within the sliding groove 34 located on the upper and lower sides of the outer wall of the sliding tube 33. A limit rod 43 is fixedly connected to the upper connecting rod 41 near the toggle plate 55. A limit block 44 is slidably connected to the periphery of the limit rod 43. A limit groove 45 is opened at the end of the limit block 44 near the limit rod 43. The limit rod 43 is located in the limit groove 45 and slidably connected to the limit groove 45. A limit hole 46 is opened on the side of the sliding groove 34 below the upper connecting rod 41 near the center of the training vehicle 1. The limit block 44 is located in the limit hole 46 and engages with the limit hole 46. The upper connecting rod 41 and the lower connecting rod 42 are connected by a... The rotating block 6 is fixedly connected and located outside the slide tube 33. Since the rotating block 6 is fixedly connected between the upper connecting rod 41 and the lower connecting rod 42, when rotating the rotating block 6, the upper connecting rod 41 and the lower connecting rod 42 need to slide in the sliding grooves 34 opened at the upper and lower ends of the slide tube 33. When the rotating block 6 is rotated to align with the through hole 32, the limiting block 44 located outside the limiting rod 43 fixedly connected to the upper connecting rod 41 is engaged in the sliding hole opened in the inner wall of the sliding groove 34, which can fix the rotating block 6. When the rotating block 6 needs to be rotated, the limiting block 44 can be pulled out from the sliding hole. The limiting groove 45 opened between the limiting rod 43 and the limiting block 44 is engaged to prevent the limiting block 44 from slipping.

[0040] A rotating groove 61 is opened at the end of the rotating block 6 away from the slide tube 33. A rotating column 62 is fixedly connected to the inner wall of the rotating groove 61. A rotating plate 63 is rotatably connected to the outer side of the rotating column 62. A rotating rod 64 is fixedly connected to the end of the rotating block 6 away from the slide tube 33 below the rotating groove 61. The rotating plate 63 can rotate around the rotating groove 61 opened in the rotating block 6.

[0041] Training mechanism 2 includes a training base 21 rotatably connected to the periphery of a rotating rod 64. The training base 21 has a rotating hole 22 on the periphery of the rotating rod 64. The rotating rod 64 is located inside the rotating hole 22 and rotatably connected to it. A support plate 23 is fixedly connected above the training base 21, and a training plate 24 is located above the support plate 23. The support plate 23 and the training plate 24 are rotatably connected via a hinge 25. A rope 26 is fixedly connected to the end of the training plate 24 away from the training vehicle 1, and a pull ring 27 is fixedly connected to the other end of the rope 26. A baffle 28 is fixedly connected to the side of the support plate 23 closest to the center of the training vehicle 1, and the baffle 28 is rotatably connected to the training plate 24. A rotating plate 63, located in a rotating groove 61 on the rotating block 6 and rotatably connected to the rotating rod, can be connected to the training plate via the hinge 25. The training board 24 is engaged with the hinge 25. A convex groove 65 is opened on the outer side of the rotating hole 22. A convex rod 66 is fixedly connected to the outer wall of the rotating rod 64. The convex rod 66 is located in the convex groove 65 and is slidably connected to the inner wall of the convex groove 65. When it is necessary to flip the training board 24, the rotating plate 63 is pulled out from between the hinge 25 and the training board 24. The training board 24 is automatically flipped by the gravity of the support plate 23. The convex rod 66 located on the outer wall of the rotating rod 64 is engaged in the convex groove 65 opened in the rotating hole 22, which can prevent the training board 24 from flipping too much. The height of the training board 24 can be adjusted by the sliding tube 33, and the patient can sit on the training board 24 to rest. It is very convenient to use. The function of the baffle 28 is to prevent the training board 24 from opening too much when it is unfolded. When the training board 24 is unfolded, it restricts the training board 24 to be perpendicular to the support plate 23.

[0042] A fixed rod 7 is fixedly connected to the training board 24 on the side away from the tube frame 31. A rotating base 71 is rotatably connected to the periphery of the fixed rod 7. A fixed cylinder 72 is fixedly connected to the end of the rotating base 71 near the support plate 23. A gasket 73 is slidably connected inside the fixed cylinder 72. A connecting rod 74 is fixedly connected to the center of the gasket 73. Multiple air vents 75 are opened on the periphery of the gasket 73 and the connecting rod 74. A fixed ring 76 is fixedly connected to the inner wall of the fixed cylinder 72 on the end away from the rotating base 71. A fixing hole 77 is opened on the end of the connecting rod 74 away from the gasket 73. A fixed column 78 is fixedly connected to the end of the support plate 23 near the connecting rod 74. The fixed column 78 is located inside the fixing hole 77 and rotatably connected to the fixing hole 77. A baffle 79 is fixedly connected to the end of the fixed column 78 away from the support plate 23. When the patient needs rehabilitation exercises, the height of the training board 24 is first adjusted through the sliding tube 33 and the adjusting mechanism 3, and the support plate 23 is then connected to the support plate 24. The training board 24 is adjusted to a suitable height. The patient places the affected limb above the support board 23 and hooks it onto the training board 24. The patient pulls the pull ring 27, which drives the training board 24 to rotate via the rope 26. At this time, the support board 23 is fixed, and the training board 24 moves towards the support board 23 via the hinge 25. When the training board 24 rotates, the connecting rod 74 located inside the fixed cylinder 72 is pulled away from the rotating base 71. Since air is released from the fixed cylinder 72 through the air outlet 75, it pushes the pad 73 to slide. The sliding speed is slow. The rotating base 71 and the fixed column 78 located at both ends of the fixed cylinder 72 are adapted to the angle of the fixed cylinder 72 when the training board 24 rotates. When a certain angle is reached, the pull ring 27 is released. At this time, the fixed cylinder 72, the pad 73, and the air outlet 75 form a damper. Air slowly enters the fixed cylinder 72, and the pad 73 pushes the connecting rod 74 out slowly to prevent violent rotation from causing secondary injury to the patient.

[0043] When patients require assisted exercise, it can be divided into two stages:

[0044] Phase 1: The patient places the affected limb on the support plate 23 and hooks it onto the training plate 24. By pulling the pull ring 27, the training plate 24 is rotated. The training plate 24 clamps the affected limb and performs flexion exercises to prevent bone, tendon, and membrane adhesions caused by prolonged lack of leg movement. When the training plate 24 returns to its original angle, the damper slowly extends, allowing the patient to adapt to slow exercise.

[0045] Second stage: During the patient's recovery period, the patient is placed on the support board 23 and hooked onto the training board 24. At this time, the pull ring 27 is not needed. The patient actively performs flexion exercises with the affected limb. The training board 24 can perform weight-bearing exercises on the affected limb through the damper, thereby enhancing the muscle adaptability of the affected limb.

[0046] Example 2,

[0047] When the patient uses the training cart 1 to assist walking, the training board 24 can be adjusted upward to the patient's back position through the adjustment mechanism 3, providing support and assistance from behind. The patient can reduce the pressure on their hands and supporting legs by leaning against it, saving the patient's energy when using it.
