[0003] Postoperative recovery walkers are usually used to help patients walk and move during the rehabilitation process after surgery. Walkers help reduce the patient's weight burden, provide stable support, and promote early rehabilitation exercises for patients. Existing walkers are generally equipped with brake devices to facilitate stable use by patients. However, in actual use, patients sometimes push the walker too fast with their hands, and the patient's footsteps can hardly keep up with the walker, making it difficult for the walker to effectively support the patient in a short period of time. Sometimes the patient does not have time to brake, which can easily cause the patient to fall due to unstable support. Utility Model Content

[0018] In this embodiment, the walker body 1 is used to assist the patient in walking exercise after surgery. The front universal wheel 11 is located below the walker body 1 in the direction of travel. The U-shaped support frame 12 is located behind the front universal wheel 11. The U-shaped support frame 12 is fixedly arranged so that the rear action wheel 2 cannot be turned. The front universal wheel 11 is responsible for the steering work. The U-shaped support frame 12 supports the two fixed covers 3. The fixed covers 3 make way for the gear ring 32 and the rotating carrier 22 through the groove 31. The two fixed covers 3 The cover 3 supports the two connecting shafts 21, the two connecting shafts 21 support the corresponding rear action wheels 2, the connecting shafts 21 support the corresponding rotating carrier 22, the rotating carrier 22 accommodates the corresponding toothed block 23 through the slide groove 221, the toothed block 23 is pulled by the elastic pull rope 4 and is stably located inside the slide groove 221, when the patient pushes the device to walk, the rear action wheels 2 roll and rotate due to the friction of the ground, the rear action wheels 2 drive the two connecting shafts 21 to rotate, and the connecting shaft 21 drives the rotating carrier The plate 22 rotates, and the rotating carrier plate 22 drives the toothed block 23 to rotate. The toothed block 23 is affected by the centrifugal force of the rotation and slides out of the slide groove 221. When the centrifugal force of the rotation of the toothed block 23 is large, the toothed block 23 can slide to the position of the toothed ring 32, and the toothed block 23 and the toothed ring 32 are meshed, so that the fixed cover 3 can limit the toothed block 23 through the toothed ring 32. The toothed block 23 drives the rotating carrier plate 22 to limit the position, and the rotating carrier plate 22 drives the connecting shaft 21 to limit the position, and the connecting shaft 21 drives the rear The moving wheels 2 are limited, so that the two rear moving wheels 2 can be emergency braked, making it difficult for the walker body 1 to continue sliding forward, preventing the walker body 1 from being far away from the patient, and being able to provide stable support to the patient, reducing the patient's fall during exercise. In addition, by adjusting the traction force of the elastic pull rope 4 on the rodent block 23, the sensitivity of the rodent block 23 when it pops out can be adjusted, thereby achieving effective braking of the device at different speeds, which is convenient for responding to the patient's usage needs in different recovery states.

[0019] One end of the toothed block 23 is fixedly connected to a sliding limit plate 24, and the sliding limit plate 24 is slidably connected to the inner wall of the slide groove 221. The toothed block 23 is limited inside the slide groove 221 by the sliding limit plate 24, and one end of the elastic pull rope 4 is fixedly connected to one end of the sliding limit plate 24; the elastic pull rope 4 pulls and pulls the toothed block 23 through the sliding limit plate 24, and when the toothed block 23 and the sliding limit plate 24 rotate and slide toward the groove 31 due to the centrifugal force, the slide groove 221 can limit the sliding limit plate 24 to prevent the toothed block 23 from driving the sliding limit plate 24 to detach from the inside of the slide groove 221, thereby ensuring the stability of the toothed block 23.

[0020] Two guide rods 222 are fixedly connected to the inner wall of the slide groove 221, and the guide rod 222 passes through one end of the sliding limit plate 24, and the sliding limit plate 24 is slidably connected to the two side walls of the sliding limit plate 24; when the sliding limit plate 24 slides inside the slide groove 221, the slide groove 221 guides the sliding limit plate 24 for sliding, so that the sliding limit plate 24 can maintain stable sliding, preventing the tooth block 23 from tilting and deviating following the sliding limit plate 24, and improving the stability of the engagement between the tooth block 23 and the groove 31.

[0021] A traction rod 41 corresponding to the elastic rope 4 is slidably connected to the inner wall of the rear action wheel 2, and the traction rod 41 is fixedly connected to one end of the corresponding two elastic ropes 4; one section of the elastic rope 4 is in the rotating carrier 22, and the other section of the elastic rope 4 is in the rear action wheel 2. The traction rod 41 controls the two elastic ropes 4 at the same time, and by changing the position of the traction rod 41 inside the rear action wheel 2, the traction rod 41 can control the length of one end of the elastic rope 4 from the sliding limit plate 24, and then adjust the traction force of the elastic rope 4 on the sliding limit plate 24, thereby realizing the ability of the tooth block 23 to connect with the tooth ring 32 under centrifugal forces of different sizes.
