[0031] As Figures 1 to 6 shown, a walking assistance device for Parkinson's patients includes a lifting rod 2 fixedly connected to the middle of a bracket 1. An extension plate 4 is fixedly sleeved on the outer surface of the lifting rod 2. A locking assembly 5 is arranged at the lower part of the extension plate 4. A protection assembly 6 is arranged at the upper part of the side of the bracket 1. A docking assembly 7 is arranged at the side of the protection assembly 6. A roller 8 is arranged on the lower surface of the bracket 1. The locking assembly 5 has the effect of locking the movement of the roller 8. Two groups of protection assemblies 6 are arranged and symmetrically distributed on both sides of the bracket 1. The docking assembly 7 acts on the protection assembly 6 to control the docking position of the docking assembly 7. The top of the lifting rod 2 is fixedly connected to a handrail 3, and the handrail 3 is arranged in a U-shaped structure;

[0032] During the use by patients, if they need to rest, the device can be limited and locked through the locking assembly 5. When patients rely on the device for support, the device will not move, improving the stability of the device. The protection assembly 6 can protect and support the legs during movement or rest. By changing the position of the protection assembly 6 and using the docking assembly 7 for limitation, it is convenient for patients to sit.

[0033] As Figure 2 、 Figure 3 and Figure 4As shown, the locking component 5 includes a vertical rod 501 that is movably inserted through the upper surface of the extension plate 4. The bottom end of the vertical rod 501 is fixedly connected to a knob 502. The lower surface of the vertical rod 501 is fixedly connected to a driving wheel 503. The lower surface of the extension plate 4 is fixedly connected to a downward seat 504. A worm gear 508 is movably inserted through the middle of the downward seat 504. The end of the worm gear 508 is fixedly connected to a driven wheel 506. The driven wheel 506 is meshed and connected to the driving wheel 503. A threaded barrel 507 is rotatably connected to the lower surface of the extension plate 4. A worm gear 508 is fixedly sleeved on the outer surface of the threaded barrel 507. The worm gear 508 is meshed and connected to a worm 505. A threaded rod 509 is threadedly connected to the inside of the threaded barrel 507. The bottom end of the threaded rod 509 is fixedly connected to a clamping seat 510. A diagonal support rod 511 is fixedly connected to the side of the lower surface of the clamping seat 510. The clamping seat 510 is clamped to the upper part of the bracket 1. A positioning groove 512 is penetrated and opened on the upper surface of the bracket 1. A positioning rod 513 is fixedly connected to the inside of the clamping seat 510. The positioning rod 513 is slidably connected to the inside of the positioning groove 512;

[0034] Rotating the knob 502 drives the vertical rod 501 to rotate, and then drives the driven wheel 506 to rotate through the driving wheel 503. The driven wheel 506 synchronously drives the worm 505 to rotate. The worm 505 further drives the worm gear 508 to rotate. Since the worm gear 508 is sleeved on the outer surface of the threaded barrel 507, the worm gear 508 will drive the threaded barrel 507 to rotate synchronously. Since the positioning rod 513 is inserted into the positioning groove 512, under the limiting effect of the positioning rod 513, the threaded rod 509 inside the threaded barrel 507 will move downward, and then will push the clamping seat 510 to be clamped to the upper part of the bracket 1. At the same time, the diagonal support rod 511 will support on the ground. And because the support directions of the two diagonal support rods 511 are opposite, a good locking effect can be achieved, achieving the effect of locking the device. When the patient uses the device for support, the device will not be pushed to move, improving the stability of the device.

[0035] As Figure 2 and Figure 5 shown, the protection component 6 includes a vertical rod 601 fixedly connected to the side of the upper surface of the bracket 1. The end of the vertical rod 601 is fixedly connected to a cross bar 602. One end of the cross bar 602 far from the vertical rod 601 is movably connected to a protection plate 603. A sponge pad 605 is fixedly connected to the outer surface of the protection plate 603. A groove 604 is opened in the middle of the top end of the protection plate 603. The cross bar 602 is rotatably connected to the inside of the groove 604;

[0036] Vertical rods 601 are arranged on both sides of the upper surface of the bracket 1. The vertical rods 601 are connected to a vertically placed protection plate 603 through the cross bar 602. When the patient is walking or resting, when the leg accidentally collides with or leans on the protection plate 603, it can be attached to the sponge pad 605, improving the comfort of the touch and also avoiding the situation of scratching.

[0037] As Figure 2 , Figure 5 and Figure 6 shown, the docking assembly 7 includes a cylinder 701 fixedly connected to the lower part of the outer surface of the protective plate 603. A slide rod 702 is movably inserted through one end of the cylinder 701 away from the protective plate 603. One end of the slide rod 702 extending out of the cylinder 701 is fixedly connected with an elastic buckle 703. The elastic buckle 703 is clamped on the outer surface of the vertical rod 601. One end of the slide rod 702 extending into the cylinder 701 is fixedly connected with a piston 704. A spring 705 is arranged inside the cylinder 701;

[0038] Rotate the protective plate 603 ninety degrees inward around the cross bar 602 to make the protective plate 603 horizontal. Then push the slide rod 702 to slide into the cylinder 701, push the piston 704 to compress the spring 705. When the elastic buckle 703 is aligned with the outer surface of the worm 505, release the slide rod 702. The spring 705 pushes the elastic buckle 703 to be clamped on the outer surface of the worm 505, achieving the effect of supporting the protective plate 603. At this time, the patient can sit on the protective plate 603, which is convenient for the patient to rest sitting when taking a break, improving the multifunctional effect of the device.

[0039] According to the technical solution provided by the present invention, when a Parkinson's patient uses the walking assistance device, the patient holds the handrails 3 with both hands and can push the device to move during walking. The rollers 8 at the bottom of the device can facilitate movement without lifting the device, achieving a labor-saving effect. When the patient wants to take a break, rotate the knob 502 to drive the vertical rod 501 to rotate, and then drive the driven wheel 506 to rotate through the driving wheel 503. The driven wheel 506 synchronously drives the worm 505 to rotate. The worm 505 further drives the worm gear 508 to rotate. Since the worm gear 508 is sleeved on the outer surface of the threaded barrel 507, the worm gear 508 will drive the threaded barrel 507 to rotate synchronously. Since the positioning rod 513 is inserted into the positioning groove 512, under the limiting effect of the positioning rod 513, the threaded rod 509 inside the threaded barrel 507 will move downward, and then push the card seat 510 to be clamped on the upper part of the bracket 1. At the same time, the inclined strut 511 will support on the ground, and because the supporting directions of the inclined struts 511 on both sides are opposite, a good locking effect can be achieved, achieving the effect of locking the device. When the patient uses the device for support, the device will not move, improving the stability of the device;

[0040] On both sides of the upper surface of the bracket 1, there are vertical rods 601. The vertical rods 601 are connected by a cross bar 602 to a vertically placed protective plate 603. When a patient accidentally collides with or leans on the protective plate 603 during walking or resting, they can lean on the sponge pad 605, improving the comfort of contact and also avoiding scratching. When the patient wants to rest, they can rotate the protective plate 603 ninety degrees inward around the cross bar 602 to make the protective plate 603 horizontal. Then, push the sliding rod 702 to slide into the cylinder 701, push the piston 704 to compress the spring 705. When the elastic buckle 703 is aligned with the outer surface of the worm 505, release the sliding rod 702. The spring 705 pushes the elastic buckle 703 to engage with the outer surface of the worm 505, achieving the effect of supporting the protective plate 603. At this time, the patient can sit on the protective plate 603, facilitating the patient to rest while sitting when taking a break, improving the multifunctional effect of the device.
