Description

Technical Field

[0001] This utility model relates to human daily necessities, and more particularly to rehabilitation training equipment, specifically a rehabilitation walking aid. Background Technology

[0002] During rehabilitation training, patients can use wheeled walking aids to practice walking and strengthen their leg muscles. As they move using the walking aid, their leg muscles need to constantly contract and relax, thus increasing muscle strength.

[0003] Existing walking aids for postoperative patients mainly include technologies such as assisting patients to walk and providing infusion storage. However, for surgical patients, the body is still relatively weak in the early postoperative period. During the recovery process, if they need to rest for a short time, they need to be helped by others to get off the walking aid, which is inconvenient. If the crossbody bag of an infant walker is used, it is also difficult for adults to get into the walking aid. Therefore, there is an urgent need for an improved technology to solve the above-mentioned problems in the existing technology. Utility Model Content

The outer surface of the vertical plate 501 is also connected to the brake block 20 through the convex shaft 504. The brake block 20 is rotatably connected to the convex shaft 504. One side of the brake block 20 is connected to the wheel body 502, and the upper surface of the other side of the brake block 20 is connected to the brake rope 19. The brake block 20 is installed through the convex shaft 504, and the brake block 20 is connected to the wheel body 502 through the lever principle, thereby achieving braking.

[0039] Furthermore, a pull-cord alarm 31 is fixedly installed on the upper U-shaped frame 8. The pull-cord alarm 31 can be the WG-AN-1 type wired emergency alarm button and matching sound and light alarm sold on Tmall Market in the existing technology. The pull-cord switch of the pull-cord alarm 31 is connected to a clip 32 through a cord. The clip 32 is clipped to the rehabilitation patient's clothes. If the rehabilitation patient accidentally collapses, the clip will pull the cord to trigger the alarm, making it easy for nurses or family members to discover it immediately.

[0040] Installation method and operating principle: First, put the connecting ring 24 with the support plate 25 onto the corresponding outer guide sleeve 9 at the open end of the upper U-shaped frame 8. Then, put the limiting ring 13 onto the outer guide sleeve 9 and tighten it with bolts. A support plate 14 is welded onto the other outer guide sleeve 9 at the open end of the upper U-shaped frame 8. When assembling the upper and lower support frames, first pass the brake rope 18 through the upper U-shaped frame 8, the outer guide sleeve 9, the inner guide sleeve, the support inclined tube 2, and the U-shaped base 1. Then, insert the outer guide sleeve 9 of the upper support frame and the inner guide sleeve 3 of the lower support frame into each other. Adjust the height of the upper support frame according to the user's height. After the height is determined, use bolts to pass through the second through hole 10 of the outer guide sleeve 9 and the corresponding first through hole 7 of the inner guide sleeve 3 and tighten them with nuts to complete the connection between the upper and lower support frames. Connect the end of the brake cable 18 away from the handbrake 17 to the brake block 19. The brake block 19 is rotatably connected to the convex shaft 504 on the outer surface of the upright plate 501 of the rear wheel 5 and is limited by a nut. At this time, when the handbrake 17 is gripped, the brake cable 18 drives the connection of the brake block 19 to lift up, and the other end of the brake block 19 presses against the wheel body 502 of the rear wheel 5, thereby realizing the handbrake 17. Finally, mate both ends of the movable semi-ring 21 with the double-layer plate 11 respectively, and use the pin 23 to pass through the fourth through hole 22 of the movable semi-ring 21 and the third through hole 12 of the double-layer plate 11 to complete the installation of the movable semi-ring 21. In use, move the tray 25 to the side of the upper support frame and lock it onto the outer guide sleeve 9 at the end of the upper U-shaped frame 8 furthest from the opening using the buckle 27. First, pull out the pin 23 at either end. The rehabilitation person enters the fixed semi-ring 20. After closing the movable semi-ring 21, the rehabilitation person is positioned inside both the fixed and movable semi-rings, with their elbows supported on the elbow rest 15 and their hands gripping the handles 16. Walking rehabilitation training is achieved through upper limb support. If the rehabilitation person needs to rest during the process, release the buckle 27 from the outer guide sleeve 9, rotate the tray 25 (rotating via the connecting ring 24), and support it laterally at the open end of the upper U-shaped frame 8. At this time, the fixing block 26 supports the tray 25, and the buckle 27 locks onto the corresponding outer guide sleeve 9. The rehabilitation person can then sit on the tray 25 to rest.This utility model has a reasonable structure. One end of the support plate 25 is rotatably connected to one of the outer guide sleeves 9 at the open end of the upper U-shaped frame 8 via a connecting ring 24. The outer end of the support plate 25 is provided with two buckles 27 via a fixing block 26. During normal rehabilitation training, the support plate 25 can be placed on one side of the walker and fixed by the buckles 27. When rest is needed, the support plate 25 is rotated so that it is laterally supported between the two outer guide sleeves 9 at the open end of the upper U-shaped frame 8. The fixing block 26 is supported on the support plate 14, and the rehabilitation patient can sit on the support plate 25, which facilitates rest. The rehabilitation patient does not need to leave the walker, greatly improving convenience. Furthermore, when folded to the side of the walker, it does not affect rehabilitation. Training; the entire unit moves through the combination of the U-shaped base 1, casters 4, and rear wheels 5. The fixed semi-ring 20 and the movable semi-ring 21 provide support and limit for the waist. Both sides of the movable semi-ring 21 are connected to the double-layer plate 11 via pins 23, allowing the user to enter or leave from either side. The upper U-shaped frame 88 has elbow supports 15 and handles 16 on both sides for easy gripping. The handles 16 are equipped with handbrakes 17, which are connected to brake blocks 19 via brake ropes 18. The brake blocks 19 are connected to the wheel body 502 of the rear wheels 5, allowing the patient to brake in time when encountering obstacles during activity, thus better ensuring activity safety.
