Technical Field
[0001] This utility model belongs to the field of walking assistance technology, specifically a rehabilitation walking assistance device. Background Technology
[0002] Walking is a complex physiological activity involving the coordinated work of multiple bodily systems. When we walk, the nervous system sends signals to the muscles, prompting the leg muscles to contract and relax, thereby driving skeletal movement. Walking can also have a positive psychological impact; appropriate walking can relieve stress, improve mood, enhance self-confidence, and even help improve cognitive abilities and creativity.
[0003] For some patients with lower limb injuries, in order to improve the recovery speed of the lower limbs, they will use walking aids for rehabilitation walking training. However, the existing walking aids are relatively simple, relying solely on simple crutches to support the body. Patients need to pick them up and walk forward slowly. When the patient's lower limb strength is insufficient, they are prone to falling, which often brings a lot of inconvenience.
[0004] Therefore, this utility model provides a rehabilitation assistive walking device. Utility Model Content
[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

With the above structure, when needed, the patient can sit on a pair of bearing plates to rest, and when the bearing plates are not needed, the bearing plates can be rotated to be close to the side wall of the protective fence to reduce the impact on the patient's lower limb movements.
[0008] Preferably, a pull rod is slidably connected to the middle of the crutch; a connecting cable is fixedly connected to the bottom of the pull rod; a second connecting rod is slidably connected inside the crutch; a second spring is fixedly connected to the side wall of the second connecting rod; the bottom end of the connecting cable is fixedly connected to the side wall of the second connecting rod; a limiting hole is provided on the side wall of the protective fence; with the above structure, after the protective fence and the crutch are connected, the crutch will not easily separate from the protective fence, so that the protective fence can be lifted by lifting the crutch to facilitate crossing some obstacles, thus improving the ease of use of the lifting device.
[0009] Preferably, a support plate is rotatably connected to the side wall of the protective fence; a limiting rope is fixedly connected to the top of the support plate; the other end of the limiting rope is fixedly connected to the side wall of the protective fence; with the above structure, items carried by the patient can be conveniently placed to reduce the patient's physical burden and improve the ease of use of the device.
[0010] Preferably, each of the pair of support plates is fixedly connected to a barbed hook and loop fastener in the middle; a flexible pad is detachably installed on the top of the pair of support plates; both ends of the flexible pad are fixedly connected to round hook and loop fasteners for connection with the barbed hook and loop fasteners; with the above structure, when the patient sits on the pair of support plates, the gap between the pair of support plates is reduced, which pinches the patient's skin and flesh, while improving the softness when sitting and reducing discomfort.
[0011] Preferably, the sidewalls of the protective fence are fixed with magnets; the tray is made of magnetic metal; through the above structure, the space occupied by the tray when it is rotated and unfolded is reduced, thereby reducing the impact on the patient's movements.
[0012] Preferably, the pull rod has a through groove in the middle; with the above structure, when it is necessary to pull the pull rod to disconnect the crutch from the guardrail, a finger can be inserted into the through groove, so that it is easy to exert force to lift the pull rod, thereby improving the ease of use of the device.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0024] like Figures 1 to 2As shown, an embodiment of the present invention provides a rehabilitation assistive walking device, comprising a pair of protective railings 1; multiple casters 12 are mounted on the bottom of the protective railings 1; a hinge 13 is fixedly connected between the pair of protective railings 1; an insertion hole 14 is provided at the top of the end of the pair of protective railings 1 away from the hinge 13; a pin 15 is slidably connected to the middle of the insertion hole 14 on one of the protective railings 1; the pin 15 is U-shaped; a crutch 16 is detachably installed in the middle of the protective railings 1; during operation, the pair of protective railings 1 are rotated apart, and then the patient enters between the pair of protective railings 1, and then the pair of protective railings 1 are rotated back together to surround the patient, and then the pin 15 is inserted into the pair of insertion holes 14. The hinge 13 and the pin 15 prevent the pair of protective railings 1 from easily... After separation, the patient's crutch 16 can be inserted into the protective fence 1, thus completing the assembly of the device. At this point, when the patient walks, the crutch 16 can be used to support the patient's upper body, or the patient can hold onto the top of the protective fence 1 for support. If the patient's lower limbs are unable to support them and they are about to fall, they can hold onto the protective fence 1 in time to support their body. At the same time, the device can be disassembled, and the patient can continue to move using only the crutch 16. Through the above structure, when using the protective fence 1 to assist the patient's walking, it can provide the patient with a relatively stable support when the patient's lower limb strength is exhausted and they are about to fall, reducing the occurrence of falls and injuries. At the same time, the crutch 16 can be easily removed and used separately as a regular walking assistance device, improving the applicability of the device.
[0025] like Figures 1 to 5As shown, a connecting seat 2 is fixedly connected to the side wall of the protective fence 1; the end of the connecting seat 2 is provided with an inclined surface, and the angle between the inclined surface and the side wall of the protective fence 1 is 45°; a connecting shaft 21 is rotatably connected to the inclined surface at the end of the connecting seat 2; a bearing plate 22 is rotatably connected to the middle of the connecting shaft 21; a first spring 23 is installed in the middle of the bearing plate 22; a first connecting rod 24 is slidably connected to the middle of the bearing plate 22; a slot 25 is provided at the end of the connecting seat 2; during operation, by rotating the bearing plate 22, the bearing plate 22 can be rotated to a horizontal or vertical state around the connecting shaft 21. After rotating a pair of bearing plates 22 to a horizontal state, the first connecting rod 24 will be inserted into the slot under the elastic force of the first spring 23. The interior of the slot 25 keeps the support plate 22 horizontal and difficult to move. At this time, the pair of support plates 22 will be joined together. When the patient feels weakness in the lower limbs during rehabilitation walking training, he / she can sit on the pair of support plates 22 to rest. When the support plates 22 are not needed, the first connecting rod 24 can be slid to separate the first connecting rod 24 from the slot 25, and then the support plate 22 can be rotated to a vertical position to reduce the impact on the patient's lower limb movement. Through the above structure, the patient can sit on the pair of support plates 22 to rest when needed, and when the support plates 22 are not needed, the support plates 22 can be rotated to be close to the side wall of the protective fence 1 to reduce the impact on the patient's lower limb movement.
[0026] like Figures 1 to 3As shown, a pull rod 3 is slidably connected to the middle of the crutch 16; a connecting cable 31 is fixedly connected to the bottom of the pull rod 3; a second connecting rod 32 is slidably connected inside the crutch 16; a second spring 33 is fixedly connected to the side wall of the second connecting rod 32; the bottom end of the connecting cable 31 is fixedly connected to the side wall of the second connecting rod 32; a limiting hole 34 is provided on the side wall of the protective fence 1; during operation, when the crutch 16 is inserted into the protective fence 1, the inclined surface below the end of the second connecting rod 32 will be blocked by the top of the protective fence 1, causing the second connecting rod 32 to slide towards the inside of the crutch 16. After the crutch 16 is inserted to the designated position, the second connecting rod 32 will slide under the elastic force of the second spring 33 and insert into the limiting hole 34. At this time, the crutch 16 and the protective fence 1 will not easily separate. This allows the healthy lower limbs to support the ground during rehabilitation walking training. By holding the crossbar in the middle of the crutch 16, the protective fence 1 can be partially lifted, enabling it to cross obstacles. When it is necessary to separate the protective fence 1 from the crutch 16, the pull rod 3 is pulled through the connecting cable 31 to pull the second connecting rod 32, causing the second connecting rod 32 to disengage from the limiting hole 34. Then, the crutch 16 can be pulled out of the protective fence 1. Through the above structure, after the protective fence 1 and the crutch 16 are connected, the crutch 16 will not easily separate from the protective fence 1. Thus, the protective fence 1 can be partially lifted by lifting the crutch 16 to cross obstacles, improving the ease of use of the device.
[0027] like Figure 1 As shown, a support plate 4 is rotatably connected to the side wall of the protective fence 1; a limiting rope 41 is fixedly connected to the top of the support plate 4; the other end of the limiting rope 41 is fixedly connected to the side wall of the protective fence 1; during operation, when the patient is undergoing rehabilitation walking training, the support plate 4 can be rotated to a horizontal position. At this time, the limiting rope 41 will pull the support plate 4 to keep it horizontal, and then some personal items can be placed on the support plate 4 to reduce the weight on the body. Through the above structure, it is convenient to place the items carried by the patient to reduce the physical burden on the patient and improve the ease of use of the device.
[0028] like Figures 1 to 4 As shown, each of the pair of support plates 22 has a bristle-faced hook and loop fastener 5 fixedly attached to its middle section; a flexible pad 51 is detachably installed on the top of the pair of support plates 22; both ends of the flexible pad 51 are fixedly attached with round-faced hook and loop fasteners for connecting with the bristle-faced hook and loop fasteners 5; during operation, after the pair of support plates 22 are rotated to a horizontal position and closed, the flexible pad 51 is attached to the pair of support plates 22 by the cooperation of the round-faced hook and loop fasteners and the bristle-faced hook and loop fasteners 5, thereby reducing the pinching of the patient's skin and flesh by the gap between the pair of support plates 22 when the patient sits on the pair of support plates 22, while improving the softness when sitting and reducing discomfort.
[0029] like Figure 1 As shown, a magnet 6 is fixed to the side wall of the protective fence 1; the tray 4 is made of magnetic metal. When the tray 4 is not in use, it can be rotated to make it fit against the side wall of the protective fence 1. At this time, the tray 4 will be attracted by the magnet 6 and will be difficult to rotate on its own, thereby reducing the space occupied by the tray 4 when it is rotated and unfolded at will, and thus reducing the impact on the patient's movements.
[0030] like Figure 3 As shown, a through groove 7 is provided in the middle of the pull rod 3; when it is necessary to pull the pull rod 3 to disconnect the crutch 16 from the protective fence 1, fingers can be inserted into the through groove 7, so that it is easy to exert force to lift the pull rod 3, thereby improving the ease of use of the device.
[0031] During operation, the pair of protective barriers 1 are rotated apart, and the patient enters between them. The barriers are then rotated back together, enclosing the patient. A pin 15 is then inserted into a pair of sockets 14. The hinge 13 and pin 15 prevent the barriers 1 from easily separating. The patient's crutch 16 can then be inserted into the barriers 1, completing the assembly. When the patient walks, the crutch 16 can support their upper body, or they can hold onto the top of the barriers 1 for support. If the patient's lower limbs become unsupported and they are about to fall, they can hold onto the barriers 1 for support. Alternatively, the device can be disassembled, allowing the patient to continue moving using only the crutch 16. By rotating the support plate 22, it can be rotated about the connecting shaft 21 to either a horizontal or vertical position. After rotating the pair of support plates 22 to a horizontal position, the first connecting rod 24 will insert into the slot 25 under the elastic force of the first spring 23, keeping the support plate 22 horizontal and difficult to move. At this time, the pair of support plates 22 will be joined together. If the patient feels weakness in their lower limbs during rehabilitation walking training, they can sit on the pair of support plates 22 to rest. When the support plates 22 are not needed, the first connecting rod 24 can be slid to separate it from the slot 25, and then the support plate 22 can be rotated to a vertical position to reduce the impact on the patient's lower limb movements. The crutches 16 are then inserted into the protective fence. When the second connecting rod 32 is inserted into the crutch 16, the inclined surface below the end of the second connecting rod 32 will be blocked by the top of the protective fence 1, causing the second connecting rod 32 to slide into the crutch 16. After the crutch 16 is inserted into the designated position, the second connecting rod 32 will slide under the elastic force of the second spring 33 and insert into the limiting hole 34. At this time, the crutch 16 and the protective fence 1 will not easily separate, so that during the patient's rehabilitation walking training, the healthy lower limb can support the ground. Then, by holding the crossbar in the middle of the crutch 16, the protective fence 1 can be lifted to allow the protective fence 1 to cross some obstacles. When it is necessary to separate the protective fence 1 from the crutch 16, the pull rod 3 is pulled through the connecting cable 31 to pull the second connecting rod 32, so that the second connecting rod 32 can be pulled from the crutch 16. Once disengaged from the limiting hole 34, the crutch 16 can be pulled out from inside the protective fence 1. When the patient is undergoing rehabilitation walking training, the support plate 4 can be rotated to a horizontal position. At this time, the limiting rope 41 will pull the support plate 4 to keep it horizontal. Then, some personal items can be placed on the support plate 4 to reduce the burden on the body. When the patient is not using the support plate 4, rotate the support plate 4 to make it fit against the side wall of the protective fence 1. At this time, the support plate 4 will be attracted by the magnet 6 and will be difficult to rotate on its own.
