[0035] Two supporting rods 4 are hinged on the backboard 3 for supporting the patient standing, as shown in Figure 2As shown in the drawings, the two supporting rods 4 are respectively hinged to the front and rear side walls of the back plate 3 through pivots, and the hinged ends of the supporting rods 4 are provided with through holes communicating with each other, and the through holes are independently provided with pivots, and the two ends of the pivots are fixed with hinge blocks, and all the hinge blocks are fixed to the back plate 3, so that the supporting rods 4 can freely swing, as shown in Figure 1 and Figure 6 When the two supporting rods 4 swing towards the patient, the supporting rods 4 will be located under the armpits of the patient, and when the back plate 3 rises, the two supporting rods 4 will support the upper body of the patient, lift the patient up, and make the patient stand upright; when the two supporting rods 4 swing towards the back of the patient, the two supporting rods 4 can be used as push handles to move the walking training device by the family members or the rehabilitation trainer;

[0036] The un-hinged ends of all the supporting rods 4 are curved upwards in the shape of a circular arc, and when the two supporting rods 4 lift the patient up, the curved ends of the supporting rods 4 can block the patient's body to prevent the patient from falling down by moving too far forward;

[0037] The un-hinged ends of all the supporting rods 4 are provided with protective sleeves 5 made of elastic materials, and the protective sleeves 5 are made of polyurethane sponge, memory foam sponge, latex sponge, etc., and the protective sleeves 5 are mainly used to make the patient more comfortable when the supporting rods 4 lift the patient up;

[0038] Further description, as shown in Figure 5 and Figure 7 In this embodiment, preferably including a screw, the supporting rod 4 is provided with a through hole for the screw to pass through, and the back plate 3 is provided with a threaded hole in threaded cooperation with the screw; when the two supporting rods 4 swing towards the back of the patient, the threaded end of the screw is inserted into the threaded hole, and the screw is rotated to press the hexagonal head end of the screw towards the back plate 3 to press the supporting rod 4, thereby fixing the swinging supporting rod 4; preventing the swinging angle from occurring when the walking training device is moved by the supporting rods 4, and more convenient to use; the whole scheme constitutes a locking assembly for locking the swinging supporting rod 4, of course, the locking assembly can also adopt a L-shaped structure of a clamping rod, the horizontal part of the clamping rod is provided with a through hole, the through hole is provided with a screw, and the back plate 3 is provided with a threaded hole in threaded cooperation with the screw, the clamping rod is connected to the back plate 3 through the screw, and the clamping rod can be rotated, when the two supporting rods 4 swing towards the back of the patient, the clamping rod is rotated to make the vertical part of the clamping rod block the supporting rod 4, thereby locking the swinging supporting rod 4.

[0039] The back plate 3 is fixed with an adjustable length of a belt 6, which is a common adjustable belt commonly used in mountaineering bags, safety belts of passenger cars, etc., and the two ends of the belt 6 are respectively fixed to the front and rear side walls of the back plate 3, and the belt 6 is provided with a connecting buckle for adjusting the length of the belt 6, and when the belt 6 is bound to the patient's body, it can prevent the patient's body from leaning forward to avoid falling down by leaning forward;

[0040] Two handrails 8 are fixed on the back plate 3, which are horizontally fixed on the front and rear sidewalls of the back plate 3, so that the patient can hold the handrails 8 when sitting or standing, thereby making the patient's body more stable when walking and playing a certain protective role.

[0041] In actual use, when the patient needs to walk, first swing the two supporting rods 4 towards the patient, and the supporting rods 4 will be located under the patient's armpit. Then, the patient's body is fixed by the belt 6, and the electric push rod 1 is started to drive the back plate 3 to rise. When the back plate 3 rises, the inner rod moves in the outer tube 2. The inner tube and the outer tube 2 cooperate to guide the moving direction of the back plate 3 and support the back plate 3 after moving to prevent the back plate 3 from tilting and falling after moving. When the back plate 3 rises, the two supporting rods 4 will serve as support for the patient's upper body, lift the patient, and make the patient stand upright. The seat plate 9 naturally swings downward to a vertical state under the action of gravity, allowing the patient to stand upright for walking training. The patient is lifted by the two supporting rods 4, making the standing process more convenient and labor-saving, and preventing the patient from falling due to unstable center of gravity during training. When the patient needs to sit down and rest due to physical exhaustion, the electric push rod 1 drives the back plate 3 to descend, and one end of the guide rod 10 on the seat plate 9 will first contact the inclined surface, causing the guide rod 10 to move to the right and drive the seat plate 9 to swing to the right, allowing the seat plate 9 to swing to a horizontal state after completely descending and abutting against the top of the support plate 11. The patient can sit on the seat plate 9 to rest, thereby allowing the patient to walk and train independently without assistance.
