That is, the sliders 10 at both ends can move downward and press down the two first support blocks 11 respectively. At this time, the two first springs 8 are stretched, and the two first springs 8 then play the role of resetting the corresponding first support blocks 11. The two first support blocks 11 respectively drive the two round rods 7 to move downwards, and at this time, the lower ends of the two round rods 7 respectively abut against the wheel surfaces of the two rubber rollers 6, thereby limiting the rotation of the rubber rollers 6 and playing the role of anti-skid and braking.

[0030] As a technical optimization scheme of the utility model, the buffer support mechanism includes a movable rod 12, and an inner cavity that slides and matches with the movable rod 12 is provided inside the inverted U-shaped support rod 2, and the movable rod 12 can move up and down.

The clamping block 17 can only affect the rotation of the cushion plate 4, and the cushion plate 4 can be rotated out with a little force. At the same time, the clamping block 17 will not affect the downward movement of the cushion plate 4, that is, after the cushion plate 4 is in a vertical state, the downward movement operation of the cushion plate 4 can still be achieved by pressing the top of the cushion plate 4.

[0037] In the utility model, the working principle of the device is as follows:

[0038] Elderly patients use this device to assist walking. During operation, the patient stands between two inverted U-shaped support rods 2 and faces the plurality of connecting rods 3. At the same time, the patient holds the top two ends of the telescopic frame 16 with both hands. The telescopic frame 16 can be adjusted in telescopic height to meet the needs of different people. Every time the patient walks, he first moves the device forward and then steps forward. When a rest is needed after walking for a long time, the cushion plate 4 can be rotated to a horizontal state, and the patient can sit on the cushion plate 4 with his back to the plurality of connecting rods 3. The plurality of connecting rods 3 can be used as a backrest. At this time, the second support blocks 14 on both sides abut against the bottom of the cushion plate 4, which can play the role of buffering and supporting the cushion plate 4 and ensure the horizontal stability of the cushion plate 4. Because the cushion plate 4 is under pressure, the sliders 10 at both ends move down synchronously and press down the two first support blocks 11 respectively. At this time, the two first springs 8 are stretched, and the two first support blocks 11 respectively drive the two round rods 7 to move downward. At this time, the lower ends of the two round rods 7 abut against the wheel surfaces of the two rubber rollers 6, thereby limiting the rotation of the rubber rollers 6 and avoiding rolling and sliding, which plays the role of anti-skid and braking. It can effectively ensure that the patient will not slide or fall when resting, ensuring the safety of the patient.

[0039] At the same time, when walking normally, the cushion plate 4 is in a vertical state. At this time, the top of the cushion plate 4 can be pressed to move the cushion plate 4 downward. The cushion plate 4 is pressed, and the sliders 10 at both ends thereof move downward synchronously and press down the two first support blocks 11 respectively. At this time, the two first springs 8 are stretched, and the two first support blocks 11 respectively drive the two round rods 7 to move downward. At this time, the lower ends of the two round rods 7 are respectively against the wheel surfaces of the two rubber rollers 6, thereby limiting the rotation of the rubber rollers 6, playing an anti-skid and braking role. That is, when walking, the cushion plate 4 can also be pressed by hand to perform an anti-skid brake operation. The overall device has a variety of flexible use effects.

[0040] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
