Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] This combination Figures 1 to 3 This describes an embodiment of a rehabilitation walking aid. Specifically, the rehabilitation walking aid is constructed as a split structure, comprising components such as a support 100, handrails 200, a support assembly 300, a locking block 301, a telescopic part, and a support bracket 302. When using the rehabilitation walking aid, the patient supports their hands on the two handrails 200 respectively. Then, according to the patient's height, the distance between the support bracket 302 and the locking block 301 is adjusted via the telescopic part, allowing the patient's chin to rest on the support bracket 302. When the patient uses the rehabilitation walking aid to assist walking, the support assembly 300 can effectively support the patient's head, reduce the burden on the neck muscles, and reduce neck fatigue, thereby improving the effectiveness and safety of rehabilitation training. It is especially suitable for users with weak neck strength or those who need rehabilitation training.

[0028] Please refer to Figures 1 to 3 A rehabilitation walking aid, including a support 100;

[0029] A pair of handrails 200 are fixed to the upper end of the bracket 100, and the two handrails 200 are placed symmetrically about the vertical plane;

[0030] The support 100 is provided with a support assembly 300, which is located on the vertical symmetrical plane of the two handrails 200. The central axis of the support assembly 300 is located in the vertical plane. The support assembly 300 includes a snap-fit ​​block 301, a telescopic part and a support bracket 302. The snap-fit ​​block 301 is used to detachably connect the support 100. The support bracket 302 is located above the snap-fit ​​block 301 and is used to support the patient's head. The telescopic part is used to adjust the distance between the snap-fit ​​block 301 and the support bracket 302.

[0031] When using the rehabilitation walker, the patient supports their hands on the two handrails 200 respectively. Then, according to the patient's height, the distance between the support bracket 302 and the locking block 301 is adjusted through the telescopic part so that the patient's chin is supported on the support bracket 302. When the patient uses the rehabilitation walker to assist walking, the support component 300 can effectively support the patient's head, reduce the burden on the neck muscles, reduce neck fatigue, thereby improving the effectiveness and safety of rehabilitation training, and is especially suitable for users with weak neck strength or who need rehabilitation training.

[0032] Preferably, the support 100 includes a bottom frame and a top frame, with the handrail 200 fixed to the top frame. The bottom frame has multiple outer tubes, and the lower end of the top frame has multiple inner tubes. The number of inner tubes is equal to that of the outer tubes, and they correspond one-to-one. Each inner tube is slidably connected to its corresponding outer tube. Both the outer and inner tubes have positioning holes. The outer tube has one positioning hole, while the inner tube has multiple positioning holes evenly distributed along its axis. Any positioning hole on the inner tube is placed coaxially with a positioning hole on the outer tube and connected by bolts. This allows for adjustment of the height of the support 100, and the handrail 200 can be adjusted to a suitable height according to the patient's actual needs.

[0033] The support 100 is equipped with an adjustment mechanism 400. The support 100 is detachably connected to the support assembly 300 through the adjustment mechanism 400. The adjustment mechanism 400 is used to drive the support assembly 300 to move horizontally in the vertical symmetrical plane of the two handrails 200, and to adjust the angle between the central axis of the support assembly 300 and the horizontal plane. This allows for adjustment of the distance between the support assembly 300 and the handrails 200 according to the length of the patient's upper limb, and control and adjust the tilt angle of the support assembly 300 according to the patient's actual needs, thereby improving the patient's comfort.

[0034] The adjustment mechanism 400 includes a pair of vertically symmetrically placed slide rods 401. The slide rods 401 are both vertically placed with respect to the vertical symmetrical plane of the two handrails 200. Each slide rod 401 has a horizontally placed slide rail 402 at both ends. A slider 403 is fixedly connected to both ends of the slide rod 401. The sliders 403 are slidably connected to the corresponding end slide rail 402. The slide rails 402 are fixed to the bracket 100.

[0035] The lower end of the snap-fit ​​block 301 is provided with a snap-fit ​​groove 3011 for placing the slide rod 401. The snap-fit ​​groove 3011 passes through both ends of the snap-fit ​​block 301 along the axis of the slide rod 401, and the groove walls on both sides of the snap-fit ​​groove 3011 are tangent to the peripheral wall of the slide rod 401.

[0036] Place the snap-fit ​​block 301 on the two slide rods 401, so that both slide rods 401 are placed in the slots 3011. The central axis of the support assembly 300 is located in the plane where the central axis of the two slide rods 401 is located. By driving the two slide rods 401 to move along the axis of the slide rail 402, the support assembly 300 can be moved closer to or away from the handrail 200 in the horizontal direction. By sliding the two slide rods 401 to different displacements, the plane where the central axis of the two slide rods 401 is located can be adjusted and controlled, so as to adjust the angle between the support assembly 300 and the horizontal plane.

[0037] It should be noted that the adjustment mechanism 400 is mounted on the top frame, and the slide rods 401 are all fixed to the upper part of the inner tube.

[0038] Preferably, a horizontally placed cushion is fixed on the bottom frame. After the snap-fit ​​block 301 is removed from the slide bar 401 and the slide bar 401 is moved to one end of the slide rail 402, the patient can sit on the cushion to rest.

[0039] To facilitate the movement of the slide bar 401 for position adjustment, the adjustment mechanism 400 also includes a first screw 404 rotatably connected to each of the two slide rails 402 at either end of the slide bar 401, which is placed coaxially. The first screw 404 passes through the slider 403 and is threadedly connected to the slider 403. A handle 405 is rotatably connected to one end of each slide rail 402 corresponding to the first screw 404. The handle 405 is coaxially fixed with the corresponding first screw 404. By rotating the handle 405, the first screw 404 is driven, which drives the first slider 403 to perform threaded transmission, thereby driving the slide bar 401 to move for position adjustment.

[0040] During the walking assistance process, in order to prevent the support component 300 from accidentally sliding along the axis of the slide bar 401, a pair of symmetrically placed limiting discs 406 are fixed on each slide bar 401. The locking block 301 is located between the two limiting discs 406, and the two sides of the locking block 301 are respectively attached to the two limiting discs 406. The limiting discs 406 effectively limit the support component 300 and prevent it from sliding accidentally.

[0041] The telescopic part includes a second screw 303 fixed to the upper end of the snap-fit ​​block 301. A threaded sleeve 304 is fitted on the second screw 303. The support bracket 302 is located at the upper end of the second screw 303. The end of the sleeve 304 away from the snap-fit ​​block 301 is fixed to the support bracket 302. By rotating the sleeve, the sleeve is threaded along the second screw 303, so as to facilitate the control and adjustment of the distance between the support bracket 302 and the snap-fit ​​block 301.

[0042] An elastic pad 3021 is fixedly connected to the end of the support 302 away from the first screw 404; preferably, the elastic pad 3021 is made of silicone or rubber material to improve the comfort of the patient's jaw support.

[0043] Preferably, the support 100 houses a walking aid board, on which two foot covers are arranged along the axial direction for placing the feet. When encountering a patient with severe hemiplegia and difficulty lifting the feet, the walking aid board is removed, and an assistant stands behind the patient. The patient places one foot in one of the foot covers, and the assistant places one foot in the other foot cover behind the patient. The assistant then lifts the patient's foot to assist in lifting the foot.
