[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 of 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 wheelchair walking aid convenient for folding and storage, including a frame one 1 and a frame two 2, which are connected by a rotating assembly, and a lifting assembly is rotatably arranged above the rotating assembly, which can facilitate the folding and unfolding operations of the whole, and is convenient for storage and use during rehabilitation, etc. In order to facilitate movement, walking wheels 9 for convenient pushing and walking are provided at the bottoms of the frame one 1 and the frame two 2, and a footrest 11 is installed at the front end through the mounting seat 10 of the placing assembly, which can conveniently place the feet and facilitate pushing and walking. The mounting seat 10 and the footrest 11 can be installed by screws, which can facilitate the rotating, storing and unfolding operations. In order to facilitate the pushing operation, adjusting devices 20 of the adjusting assembly are provided at the rear ends of the frame one 1 and the frame two 2, and an extension rod 21 is inserted into the adjusting device 20. The top end of the extension rod 21 is fixedly connected to the armrest 4. For the adjusting device 20 and the extension rod 21, they can be composed of a sleeve, a screw and an adjusting hole on the extension rod 21, which can conveniently adjust the height of the armrest 4 according to needs, and then facilitate the promotion of rehabilitation. A braking device is also provided on the armrest 4. The walking wheels 9 (rear wheels) adopt a band brake system, which is a relatively mature technology and will not be elaborated here. It can conveniently brake the walking wheels 9 according to needs. A backrest 3 is provided between the frame one 1 and the frame two 2, which can conveniently lift the back when sitting. The material can be a soft material such as breathable fabric, etc., as long as it does not affect the protective lifting during folding, storage and unfolding. It is a relatively mature technology and will not be elaborated here. For the backrest 3, its two ends can be connected to the frame one 1 and the frame two 2 by screws, and at the same time, when used as a walking aid, it can be rotated upwards by 180° ( Figure 1 in which the backrest 3 rotates 180°), and when used as a wheelchair as shown in Figure 1 .

[0024] Please refer to Figures 1-6, and for convenient folding and storage, it can also be unfolded during use while ensuring safety. A rotating frame one 19 is rotatably provided on the side wall of the frame one 1, and a rotating frame two 13 is rotatably provided on the side wall of the frame two 2. The two have the same structure and are symmetric along the center. Moreover, the rotating frame one 19 and the rotating frame two 13 are rotatably connected to facilitate the approach and separation of the frame one 1 and the frame two 2, realizing the folding and unfolding operations. Rotating members 18 are welded on the side walls of both the frame one 1 and the frame two 2. A support plate 17 is rotatably provided at the end of the rotating member 18. The two support plates 17 are rotatably connected by a rotating shaft 16 and can rotate upward when the frame one 1 and the frame two 2 approach each other. To ensure comfort when sitting, a seat cushion 12 can be adhered to the support plate 17. To ensure safety during unfolding, when the support plate 17 is horizontally unfolded, its bottom contacts the tops of the rotating frame one 19 and the rotating frame two 13, which can prevent it from rotating downward and lift it. At the same time, a clamping plate 14 of the positioning component is provided between the two support plates 17. The front end of the clamping plate 14 is threadedly engaged with an adjusting bolt 15. By rotating the adjusting bolt 15, the rotating shaft 16 can be tightened to prevent rotation during unfolding and storage, ensuring safety. At the same time, to ensure safety when sitting and play a protective effect, fixing blocks 5 of the protective component can be welded at the front ends of the frame one 1 and the frame two 2. A connecting belt 6 is adhered to the front side wall of the fixing block 5. A connecting buckle 8 is fixedly provided on the connecting belt 6 of the frame one 1, and connecting holes 7 matching the connecting buckle 8 are equidistantly opened on the connecting belt 6 of the frame two 2. For the connecting buckle 8 and the connecting holes 7, they can also be replaced by Velcro, etc., to facilitate the protection of the front end of the user and prevent tipping.

[0025] Working principle: When the utility model is in use and needs to be unfolded, by loosening the adjusting bolt 15, the limiting effect on the rotating shaft 16 is lost. By pulling the first frame 1 and the second frame 2, they move away from each other under the action of the walking wheels 9, and the first rotating frame 19 and the second rotating frame 13 rotate and open. At the same time, the support plate 17 rotates and unfolds in cooperation with the rotating member 18 and the rotating shaft 16. After being flattened, by tightening the adjusting bolt 15 and cooperating with the clamping plate 14, the rotating shaft 16 can be limited. At the same time, the tops of the first rotating frame 19 and the second rotating frame 13 contact the bottom of the support plate 17 to lift it, which can ensure the stability during use. At this time, the user can perform rehabilitation training or sit as needed. When performing walking rehabilitation and other walking aids, the height of the armrest 4 can be adjusted by the adjusting device 20 and the extension rod 21 to adapt to the user. The user can push the armrest 4 and cooperate with the walking wheels 9 to perform walking rehabilitation and other walking aids. When needing to sit, sit on the cushion 12 on the support plate 17, place the feet on the footrest 11, and then connect and fix the connecting belt 6 through the connecting hole 7 and the connecting buckle 8, so as to protect the front end of the user and ensure safety when pushing and walking. When needing to fold and store the whole, by loosening the adjusting bolt 15, the limiting of the rotating shaft 16 is lost. First, push up the support plate 17 (the ends where the two support plates 17 are close to each other), that is, pull up the two support plates 17, which can rotate in cooperation with the rotating shaft 16 and the rotating member 18. Then, the second rotating frame 13 and the first rotating frame 19 rotate, and the first frame 1 and the second frame 2 approach each other in cooperation with the walking wheels 9 for folding and storage. Then, tighten the adjusting bolt 15 to prevent the situation of rotating and unfolding, without occupying space, and it is convenient to store and place it.

[0026] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, it is intended to embrace all changes falling within the meaning and scope of the equivalent elements of the claims in the present utility model. Any reference signs in the claims should not be regarded as limiting the claimed rights.
