When the buffer block provided at the bottom of the support block contacts the ground, the support block stops rotating, and the patient is supported by the support block and a pair of supporting legs at the rear of the walking frame, thereby preventing the patient from continuing to lean back and causing serious injuries, thereby improving the safety protection effect of the device.

[0016] (2) The angle-fixing assembly and height-adjusting assembly provided in the present invention can make the device adaptable to patients of different heights and body shapes. When it is necessary to lock the angle of the rotating frame through the angle-fixing assembly, the cam where the shifting block is located is rotated through the shifting block. Since the cam is hinged at one end of the sliding rod, and the sliding rod is simultaneously passed through two friction plates connected by a spring, the cam will squeeze the friction plate in contact with its outer side, so that the friction plate is close to the other friction plate to clamp the friction wheel. When the friction wheel is locked in rotation, the coaxially connected sliding button and the rotating frame will also be locked in rotation, and the angle control of the rotating frame is completed at this time.

[0017] (3) The support plate and gripping rod provided in the present invention can change the posture of the patient when manipulating the walker, so that the body weight is borne by the entire arm, thereby reducing the force on the patient's wrist and avoiding the compression pain caused by the traditional underarm support. The height of the support plate is adjusted by the telescopic rod so that the support plate is moved to the height of the patient's arm when walking and standing normally. When using the walker, the patient puts both arms in the grooves provided at the top of the support plate and holds the gripping rods symmetrically provided on both sides of the walker.

A first magnetic block 16 and a second magnetic block 17 are arranged on the outside of any friction plate 18, and the paddle 14 is attracted to one end of the first magnetic block 16 or the second magnetic block 17.

[0024] like Figure 4 and Figure 5 As shown, a height adjustment component is provided on the other support rod 30, and the height adjustment component includes a screw 28 rotatably mounted on the support rod 30, a knob 27 is coaxially connected to the top of the screw 28, a slider 33 is passed through the screw 28, a fixed shaft 32 is provided on the outer side of the slider 33, and the fixed shaft 32 is rotatably mounted on the free end of the rotating frame 24.

[0025] The angle-fixing assembly and the height-adjusting assembly can make the device adaptable to patients of different heights and body types. When the angle of the rotating frame 24 needs to be locked by the angle-fixing assembly, the cam 13 where the dial block is located is rotated by the dial block. Since the cam 13 is hinged at one end of the slide bar 12, and the slide bar 12 is simultaneously inserted between two friction plates 18 connected by the spring 10, the cam 13 will squeeze the friction plate 18 in contact with the outer side thereof, so that the friction plate 18 is close to the other friction plate 18 to clamp the friction wheel 26.

[0028] like Figure 1 As shown, a pair of stabilizing rods 3 are provided at one end of the walking frame 2, and both ends of the two stabilizing rods 3 are connected to the walking frame 2. A counterweight is provided in the lower stabilizing rod 3. The stabilizing rod 3 strengthens the structure of the walking frame 2 and can adjust the center of gravity offset of the walking frame 2 caused by the setting of the balance component.

[0029] like Figure 1 and Figure 4 As shown, telescopic rods 21 are symmetrically arranged on both sides of the walking frame 2, and the output ends of the telescopic rods 21 are connected to the supporting plates 20, and the top of the supporting plates 20 is provided with a groove 19.

[0030] like Figure 1 and Figure 4 As shown, grip bars 1 are symmetrically arranged on both sides of the walking frame 2. The grip bars 1 are arranged close to the stabilizing bars 3. The extending direction of the grip bars 1 is tangentially perpendicular to the bottom end of the support plate 20.

[0031] The support plate 20 and the grip bar 1 can change the patient's posture when manipulating the walker 2, so that the body weight is borne by the entire arm, thereby reducing the force on the patient's wrist and avoiding the compression pain caused by traditional underarm support. The height of the support plate 20 is adjusted by the telescopic rod 21 to move the support plate 20 to the height of the patient's arm when walking and standing normally.

The height and angle of the rotating frame 24 are first adjusted by the angle-fixing assembly and the height-adjusting assembly, so that the protective pad 22 provided on the inner side of the rotating frame 24 fits the patient's back, and then the patient can use the walking frame 2 for rehabilitation training. When the patient falls backwards, the patient will press the rotating frame 24 backward through the protective pad 22, and the rotating frame 24 will synchronously drive the support rods 30 provided on both sides thereof to rotate along the first connecting shaft 8 provided in the storage groove 9. Since the first gear 35 provided at one end of the support rod 30 and the second gear 5 provided at one end of the support rod 6 The support rod 6 is meshed, so the support rod 6 will rotate backward under the drive of the support rod 30. At the same time, the first connecting block 29 hinged on the outer sides of the two support rods 30 will press down the second connecting block 34, so that the buffer rod 31 connected to the second connecting block 34 slides along the buffer tube 15. The sliding speed of the buffer rod 31 is controlled by the exhaust hole opened at the bottom end of the buffer tube 15 to prevent the rotating frame 24 from rotating backward too fast and causing excessive impact on the patient. When the buffer block 7 set at the bottom end of the support block contacts the ground, the support block stops rotating, and the patient is supported by the support block and a pair of supporting legs at the rear of the walking frame 2, thereby preventing the patient from continuing to lean back and causing serious injury, thereby improving the safety protection effect of the device.
