[0020] The following describes in detail the implementation of the walking aid for ankle sprains and ankle ligament injuries of this utility model with reference to the accompanying drawings and embodiments.

[0021] Please see Figure 1 As shown, the present invention discloses a walking aid for ankle sprains and ankle ligament injuries, comprising a chassis 1, a support assembly 4 fixed to the top of the chassis 1, a leg support 2 fixed to the top of the support assembly 4, and an auxiliary assembly 3 installed on the front side of the leg support; a pulley assembly 6 is installed at the bottom of the chassis 1, the leg support 2 has a groove 20 for placing the leg horizontally, and the front end of the groove 20 is bent upward to form a knee support 21 covering the knee joint; the auxiliary assembly 3 includes a lower support rod 30 fixed to the bottom of the chassis 1, an inclined support rod 31 extending outward from the top of the lower support rod 30, and an upper support rod 32 extending upward from the upper end of the inclined support rod 31, and a hand-held mechanism 5 is installed at the top of the upper support rod 32.

[0022] One end of the inclined support rod 31, which connects to the lower support rod 32, extends toward the support assembly 4 and connects to the support assembly 4. The auxiliary assembly 3 can be held in hand to keep the walker stable during walking and prevent falls.

[0023] The support assembly 4 includes a fixed rod 40 fixedly connected to the chassis 1 and a sleeve 41 sleeved on the upper part of the fixed rod 40. The sleeve 41 is provided with a plurality of adjustment holes 42, and the fixed rod 40 is provided with telescopic pins 43 at positions corresponding to the adjustment holes 42. One end of the inclined support rod 31 extending toward the support assembly 4 is fixedly connected to the side wall of the fixed rod 40. Specifically, the adjustment holes 42 are arranged in parallel at intervals along the longitudinal direction, the fixed rod 40 is provided with pin holes, and the inner side of the telescopic pin 43 is fixed to the pin hole by an elastic element. When not under pressure, the telescopic pin 43 can protrude outward and be limited by the adjustment hole 42. When adjustment is required, the telescopic pin 43 is retracted into the pin hole by pressing down with a finger, and then the sleeve 41 is moved up and down for adjustment. This adjustment device is a telescopic rod device commonly used in the art.

[0024] The chassis 1 adopts a foot-shaped, elliptical, or rectangular plate structure. This structure has a large stress-bearing surface, which helps to maintain the stability of the walking aid during use.

[0025] Figure 2 As shown, the pulley assembly 6 includes mounting brackets respectively located on the front and rear sides of the bottom of the chassis 1, and a wheel 61 located below the mounting brackets. The wheel 61 is a swivel wheel. The mounting bracket includes a mounting frame 62 fixed to the bottom of the chassis 1 and a fixed plate 63 connected to the top of the wheel 61. Specifically, an auxiliary plate 630 is provided in the middle of the bottom of the fixed plate 63, and an annular groove 631 is carved out at one end of the auxiliary plate 63 connected to the fixed plate 63; a rotating frame 611 is provided on the top of the wheel 61 and fits into the annular groove 631. The mounting frame 62 has downwardly extending lugs 621 on a pair of side edges, and the inner sidewall of the lugs 621 has a limiting groove 622. The fixed plate 63 has a limiting rod 632 on its side that is fitted with the limiting groove 622. The height of the limiting rod 632 is less than the height of the limiting groove 622, allowing the wheel 61 to move slightly up and down. The top of the fixed plate 63 is connected to the top surface of the mounting frame 62 by an elastic element 64. The elastic element 64 is a spring with a height of 0.5-1cm, which allows the chassis to tilt slightly forward and backward under the drive of lower limb movements, adapting to the angle changes during lower limb movement, and ensuring easy and stable movement while bearing a slight load during lower limb walking.

[0026] To accommodate patients of different heights, the upper support rod 32 is an adjustable rod. The length adjustment device can be a conventional length adjustment device or the same adjustment device used in the support assembly.

[0027] An adjustment strap is connected to the rear side of the knee brace 21; an adjustment strap is also connected to the upper side of the bracket 20. The adjustment strap can be any conventionally used adjustment strap, such as one connected via a D-ring. To improve comfort, a protective sleeve can also be provided at the connection point of the adjustment strap.

[0028] The hand-held mechanism 5 is a ring structure arranged longitudinally around the perimeter. A plastic grip sleeve 55 is fitted onto the upper part of the ring. The plastic grip sleeve 55 has a groove that adapts to the shape of the fingers when the hand is gripping, so as to improve the comfort of the patient holding the hand.

[0029] The upper part of the support component 4 is provided with a reinforcing rib 7 that is fixed to the bottom of the bracket 20. The reinforcing rib 7 is arranged around the sleeve 41 of the support component 4 to enhance the load-bearing capacity of the support component.

[0030] When using this aid, patients with lower limb injuries bend their legs, placing their lower legs horizontally into the support brackets. Once the lower legs are in the brackets, the knee also engages in the knee brackets, allowing the lower limb to bend and lift off the ground. The lower limb support component then takes over the walking aid from the bent leg. During walking, the patient can hold the handle and drag the walker for easy movement. This device ensures that excessive weight is not placed on the injured area, while also allowing for faster and more stable walking. During walking, the chassis can tilt slightly forward and backward under the drive of lower limb movements, adapting to changes in angle during lower limb movement. This walker ensures that walking involves a light load to prevent muscle atrophy in the lower limbs, while avoiding excessive weight-bearing that could affect ankle joint rehabilitation. It also allows for easy and stable movement, providing a high level of comfort.

[0031] The above-described embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made by those skilled in the art to the technical solutions of the present utility model without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
