Specific embodiments

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1 - 6 , an embodiment provided by the present utility model: A walking aid for rehabilitation includes a vehicle frame 1, at the bottom of the front end of which two groups of front walking wheels 5 are symmetrically installed, and at the rear end, two groups of rear walking wheels 6 are symmetrically installed, which can facilitate the user to assist walking during rehabilitation. In order to facilitate pushing and walking while holding, a handrail 2 is installed on the top of the vehicle frame 1 through a plug-in mechanism, which is convenient for the user to hold the handrail 2 and push, facilitating rehabilitation training. A placement frame 3 of the placement component can be fixedly installed on the vehicle frame 1 through bolts, and daily necessities such as tissues and medicines can be placed inside it. The opening end of the placement frame 3 can be clamped with a cover plate 4, and the two can be connected and sealed through a sealing device (such as a sealing strip and a sealing groove) to ensure the sealing performance;

[0024] In order to enable the user to perform a braking operation according to their own situation during the rehabilitation walk and stop conveniently, a lifting ring 8 of the braking mechanism is rotatably arranged under the handrail 2. When holding the handrail 2, the lifting ring 8 can be hooked by the thumb. In order to facilitate the pulling operation, two groups of suspension rings 10 are arranged on the lifting ring 8 through a connecting rope, which can be conveniently sleeved on the thumb to facilitate the rotation of the lifting ring 8. The two ends of it are connected with a brake wire 9, and a brake pad 7 is provided through a spring 12 (a relatively mature technology, not elaborated here). The brake pad 7 is rotatably connected to the vehicle frame 1 through a rotating member 13, which can facilitate pulling the lifting ring 8 and driving the brake pad 7 to rotate and fit with the rear walking wheel 6 for braking.

[0025] Please refer to Figures 1 - 6 , and in order to adjust the walking speed and resistance of the walking aid according to the user's situation, it can avoid the inconvenient person walking too fast during rehabilitation use and can be adjusted according to the rehabilitation needs. The front ends of the bottom of the frame 1 are symmetrically welded with connecting plates 19 of the adjusting mechanism. A sliding hole for the smooth up and down sliding of the sliding column 20 is provided in the middle of the connecting plate 19. The two side walls of the connecting plate 19 are threadedly engaged with fastening bolts 21 for firmly fixing the sliding column 20. The bottom end of the sliding column 20 is welded with a pressing plate 22 of the friction assembly. An anti-slip gasket 11 is adhered to the bottom end of the pressing plate 22, which is convenient for adjusting the distance between the anti-slip gasket 11 and the front walking wheel 5, and thus the friction force during contact can be adjusted, and the resistance during walking can be adjusted as needed.

[0026] Please refer to Figures 1 - 6 , and in order to be suitable for different people to use and facilitate the adjustment of the height of the armrest 2, the adjusting insertion rods 14 of the insertion mechanism are symmetrically welded to the armrest 2. The frame 1 is provided with insertion holes adapted to be inserted thereinto. In order to perform positioning and fixing after adjustment, a clamping block 16 of the positioning assembly is welded to the top end of the frame 1, and a positioning clamping plate 17 is clamped on its side wall. It can be movably inserted in a snap-fit or plug-in manner. A positioning column 18 is welded to the inner arc surface of the positioning clamping plate 17, and a plurality of groups of positioning holes 15 are provided on the adjusting insertion rod 14, which can be conveniently adjusted to be suitable for different heights and are suitable for different people.

[0027] Working principle: When the present utility model is in use, when using the walking aid, the position of the anti-slip gasket 11 under the pressing plate 22 can be adjusted according to the user's state. For those with relatively inconvenient walking, the sliding column 20 can be pushed downward to move the pressing plate 22 downward, and the anti-slip gasket 11 is attached to the front walking wheel 5. By tightening the fastening bolt 21, the sliding column 20 can be fixed, and thus the resistance during subsequent pushing and walking can be increased, thereby slowing down the walking speed and ensuring safety. When a person with relatively convenient walking uses it, the sliding column 20 can be pulled upward to move the pressing plate 22 upward, and thus the resistance of the front walking wheel 5 during walking can be reduced, which is convenient for pushing during rehabilitation walking. According to the user, the height of the armrest 2 is adjusted for convenient pushing. The positioning clamping plate 17 is removed from the clamping block 16, and the positioning column 18 leaves the positioning hole 15, which can conveniently adjust the adjusting insertion rod 14. It can be adjusted in the insertion hole of the frame 1. When adjusted to a suitable height, by inserting the positioning clamping plate 17 into the clamping block 16, at this time the positioning column 18 enters the positioning hole 15, and the adjusting insertion rod 14 can be positioned and fixed to ensure the stability of the armrest 2. The user can hold the armrest 2 with both hands. If the thumb cannot reach the lifting ring 8, the hanging ring 10 can be sleeved on the thumb. When it is necessary to brake and stop, by lifting the thumb upward, the lifting ring 8 can be rotated, and thus in cooperation with the brake wire 9, the spring 12 and the rotating member 13, the brake pad 7 can be rotated to contact and brake the rear walking wheel 6, thereby completing the parking operation.
