[0021] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0022] like Figures 1-3 As shown, this embodiment provides a child rehabilitation walking aid, including a base frame 1. Connecting seats 2 are installed at the four corners of the bottom of the base frame 1. The connecting seats 2 connect the base frame 1 and the moving wheels 3. The moving wheels 3 are fixed to the bottom of the connecting seats 2, and the moving wheels 3 can drive the walking aid to move. A frame 4 is installed at the top of the base frame 1. The frame includes an upper body support frame 8. A protective mechanism 5 is provided on one side of the upper body support frame 8. The protective mechanism 5 includes a main frame 501 located inside the frame 4. The main frame 501 can support a limiting plate 503. Multiple sets of compression springs are equidistantly installed at one end of the main frame 501. Spring 502, through the elasticity of compression spring 502, can reduce the pressure of limit plate 503 on the child's back. One end of compression spring 502 is fixed to limit plate 503, which can support the child's back. Guide rods 504 are symmetrically installed on the other side of main frame 501. Guide rods 504 can move along support frame 403 to guide main frame 501. Adjusting screw 505 is rotatably connected on main frame 501 between the two sets of guide rods 504. When the operator rotates adjusting screw 505, it can drive main frame 501 to move horizontally.

[0023] like Figures 1-3 As shown, the guide rod 504 is slidably connected to the upper support frame 8, and the adjusting screw 505 is threadedly connected to the frame 4, so that the adjusting screw 505 can guide the main frame 501 through the guide rod 504 when it drives the main frame 501 to move.

[0024] like Figure 1 As shown, the frame 4 includes a connecting sleeve 401, a support rod 402 and a support frame 403. The connecting sleeve 401 is fixed on the upper support frame 8, which facilitates the connection of the support rod 402 and the base frame 1 through the connecting sleeve 401.

[0025] like Figure 1As shown, the support rod 402 is fixed on the connecting sleeve 401, and the support frame 403 is slidably connected to the support rod 402. A protective sleeve is installed on the outside of the support frame 403, which facilitates the support rod 402 to support the support frame 403 and allows the height of the support frame 403 to be adjusted. The protective sleeve can protect the upper body of the child.

[0026] like Figure 1 As shown, the support rod 402 is connected to the outside by a positioning bolt 7 via a thread, and the support frame 403 has multiple sets of positioning holes 6 corresponding to the positioning bolt 7, which makes it convenient for the staff to rotate the positioning bolt 7 into the positioning holes 6 at different heights, thereby adjusting the height of the support frame 403 to meet the usage needs of children of different heights.

[0027] like Figure 1 As shown, grip rods 9 are symmetrically installed on the support frame 403 on the side away from the protective mechanism 5, and protective sleeves 10 are fixed on the outside of the grip rods 9, so that children can hold the grip rods 9 to move, and the protective sleeves 10 protect the children's hands.

[0028] like Figure 1 As shown, there are four movable wheels 3 in total, two of which are omnidirectional and all four have a self-locking mechanism, which makes it easy for the walker to move freely using the movable wheels 3.

[0029] The working principle of this device is as follows: In practical use, the child first enters the support frame 403 and the upper body support frame 8. Then, the operator adjusts the height of the support frame 403 according to the child's height. After adjustment, the operator rotates the positioning bolt 7, which moves into the positioning holes 6 at different heights, thus fixing the support frame 403 and the support rod 402. After fixing, the operator rotates the adjusting screw 505 according to the child's upper body size. As the adjusting screw 505 rotates along the support frame 403, it moves the main frame 501, simultaneously causing the guide rod 504 to move horizontally along the support frame 403 until the limiting plate 503 inside the main frame 501 contacts the child's back. The limiting plate 503 restricts the child's upper body. During use, the limiting plate 503, through the compression spring 502, moves within the main frame 501, reducing pressure on the child's back. This device can meet the needs of children of different sizes, has strong adaptability, and provides good protection, preventing potential safety hazards. When a child uses the device, they hold the handle bar 9 with their hands, and the upper body support frame (8) can be located under the patient's armpits to provide some support for the patient's upper body. Then, the child moves their legs, which in turn drive the walker to move through the moving wheels 3 at the bottom of the connecting seat 2. The child's hands can be protected by the protective cover 10 during use.

[0030] The above are merely further embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope disclosed by this utility model, based on the technical solution and concept of this utility model, shall fall within the protection scope of this utility model.
