Description

Technical Field

[0001] This utility model relates to the field of walking aids, specifically a nursing and rehabilitation walking aid. Background Technology

[0002] A walking aid is an assistive device used to help people with mobility impairments walk. It typically includes two or four support points to provide stability and support. It usually has handles for users to hold and sometimes wheels for easier movement. Walking aids can help users maintain balance, reduce weight burden, and provide additional support. They are suitable for people with limited mobility or who need rehabilitation.

[0003] A common way to fold a nursing rehabilitation walking aid is to fold the main structure at specific joints to reduce its size and make it easier to carry. This usually involves compressing the handle so that the side support structures can fold inward at the joints, thereby reducing the overall volume.

[0004] In existing technologies, the structural stability is poor when folded through specific joints, the folded parts are prone to wear, and the service life is relatively short. In addition, the stability and load-bearing capacity of the walking aid may be reduced when folded. To address these issues, a nursing rehabilitation walking aid is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a nursing rehabilitation walking aid that solves the problem of poor folding stability in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a nursing rehabilitation walking aid, comprising several columns, several first connecting rods fixedly connected to the outer ring of each column, a first fixing block fixedly connected to the bottom center of the outer ring of the column at the front end, a second connecting rod rotatably connected to the inner wall of the first fixing block, a first hinge provided at the rear end of the second connecting rod, a second fixing block fixedly connected to the top center of the column at the middle end, a rotating shaft rotatably connected to the front end of the second fixing block, a folding plate rotatably connected to the outer ring of the rotating shaft, the bottom of the folding plate contacting the second connecting rod, a second hinge provided at the bottom of the folding plate, a thick rod fixedly connected to the bottom of the outer ring of the column, a thin rod slidably connected to the inner wall of the thick rod, a first spring fixedly connected to the inner wall of the thin rod, a buckle fixedly connected to the top of the first spring, a handle fixedly connected to the top of the column at the front end, and a brake assembly provided at the front end of the handle.

[0007] By adopting the above technical solution, pressing the buckle can compress the first spring, thereby causing the buckle to retract into the interior of the thin rod. This allows the thick rod to move, enabling the thin rod to enter the interior of the thick rods on both sides. After contacting the fixation between the thin rod and the thick rod, the folding plate can be folded, thus achieving folding.

[0008] As a further description of the above technical solution: the brake assembly includes a button, which is slidably connected to the front end of the handle, a piston shaft is fixedly connected to one end of the button, a fourth fixing block is slidably connected to the outer ring of the piston shaft, a second spring is fixedly connected to the front end of the fourth fixing block, and one end of the second spring is fixedly connected to the button, and a first piston is fixedly connected to one end of the piston shaft.

[0009] By adopting the above technical solution, pressing the button can move the first piston and apply pressure to the hydraulic oil. If the button is not pressed manually, the second spring will return the button to its original position.

[0010] As a further description of the above technical solution: a third fixing block is fixedly connected to the bottom of the outer ring of the rear column, and a hydraulic oil groove is opened inside the third fixing block.

[0011] By adopting the above technical solution, hydraulic oil is stored inside the hydraulic oil tank, and the hydraulic oil can provide hydraulic pressure, thereby enabling braking.

[0012] As a further description of the above technical solution: the inner wall of the third fixed block is slidably connected to a second piston, and the other side of the second piston is slidably connected to a hydraulic oil groove.

[0013] By adopting the above technical solution, the second piston will push the brake block to move after being subjected to hydraulic pressure.

[0014] As a further description of the above technical solution: a brake block is fixedly connected to one side of the second piston, and the outer ring of the brake block is slidably connected to the third fixed block.

[0015] By adopting the above technical solution, the brake block can contact the swivel wheel, thereby stopping the swivel wheel from moving.

[0016] As a further description of the above technical solution: a rubber pad is fixedly connected to the bottom of the front column.

[0017] By adopting the above technical solution, the rubber pad can effectively absorb impact and vibration, and prevent the casters from moving too fast.

[0018] As a further description of the above technical solution: a caster wheel is fixedly connected to the bottom of the rear column, and one side of the caster wheel is in contact with the brake block.

[0019] By adopting the above technical solution, the caster wheel can drive the whole body to move, and the brake block contacts the caster wheel to prevent the caster wheel from rotating again.

[0020] As a further description of the above technical solution: a cushion is provided on the top of the folding plate.

[0021] By adopting the above technical solution, the cushion allows one to sit above the folding board.

[0022] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0023] 1. The nursing and rehabilitation walking aid provided by this utility model first involves taking out the seat cushion, pressing the buckle to allow the buckle to enter the interior of the thin rod, pushing the two side pillars inward, and the thin rod completely entering the interior of the thick rod. At the same time, the second connecting rod moves inward through the first hinge, and the folding plate moves upward through the second hinge, thereby completing the folding of the walking aid and achieving a compact and stable combination.

[0024] 2. This utility model provides a nursing and rehabilitation walking aid. By pressing a button, the pressure causes the first piston to compress the hydraulic oil in the hydraulic oil tank. The pressurized hydraulic oil causes the second piston in the third fixed block to move forward. The second piston drives the brake block to move, and friction is generated between the brake block and the caster wheel, causing the caster wheel to stop moving. Releasing the second spring that presses the button returns the button to its original position, thus effectively stopping the movement of the caster wheel. Braking and releasing are achieved by simply pressing the button, making operation convenient. Attached Figure Description

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] To further understand the contents of this utility model, a detailed description of this utility model will be provided with reference to the accompanying drawings.

[0035] Reference Figure 1 This utility model discloses a nursing rehabilitation walking aid, which includes several columns 1. A rubber pad 24 is fixedly connected to the bottom of the front column 1, and a caster wheel 25 is fixedly connected to the bottom of the rear column 1. The caster wheel 25 can drive the movement of the whole device and move flexibly. One side of the caster wheel 25 contacts the brake block 23. The contact between the caster wheel 25 and the brake block 23 will generate friction, which can force the caster wheel 25 to stop. A seat cushion 26 is provided on the top of the folding plate 11. When you need to rest, you can sit on the seat cushion 26.

[0036] Reference Figures 2-4A number of first connecting rods 2 are fixedly connected to the outer ring of the column 1. A first fixing block 7 is fixedly connected to the bottom middle of the outer ring of the front column 1. A second connecting rod 8 is rotatably connected to the inner wall of the first fixing block 7. A first hinge 9 is provided at the rear end of the second connecting rod 8. The first hinge 9 can make the second connecting rods 8 on both sides move inward or outward at the same time. When the second connecting rod 8 is under force, it can only move inward. A second fixing block 12 is fixedly connected to the top middle of the column 1. A rotating shaft 13 is rotatably connected to the front end of the second fixing block 12. A folding plate 11 is rotatably connected to the outer ring of the rotating shaft 13. The rotating shaft 13 can make the folding plate 11 rotate around the rotating shaft 13. The bottom of the folding plate 11 is connected to the second connecting rod 8. When unfolded, the second connecting rod 8 can support the folding plate 11. The bottom of the folding plate 11 is provided with a second hinge 10. The second hinge 10 allows the folding plates 11 on both sides to move inward or outward simultaneously. Under force, the folding plate 11 can only move upward. A thick rod 3 is fixedly connected to the bottom of the outer ring of the column 1. A thin rod 4 is slidably connected through the inner wall of the thick rod 3. A first spring 6 is fixedly connected to the inner wall of the thin rod 4. A buckle 5 is fixedly connected to the top of the first spring 6. When the first spring 6 is compressed, the buckle 5 can enter the interior of the thin rod 4. When the first spring 6 is in a normal state, the buckle 5 can fix the thin rod 4. A handle 15 is fixedly connected to the top of the front column 1. A brake assembly is provided at the front end of the handle 15.

[0037] Reference Figure 5 and Figure 6 The braking assembly includes a button 20, which is slidably connected to the front end of a handle 15. The handle 15 provides a stable support point for the user, helping them stand up or maintain balance. A piston shaft 17 is fixedly connected to one end of the button 20. A fourth fixing block 18 is slidably connected to the outer ring of the piston shaft 17. The fourth fixing block 18 is fixedly connected to the inner wall of the handle 15, allowing the second spring 19 to be compressed. The second spring 19 is fixedly connected to the front end of the fourth fixing block 18. When the second spring 19 is compressed, the button 20 is pushed into the interior of the handle 15. When the button 20 is not pressed, the second spring 19 returns the button 20 to its original position, and one end of the second spring 19 is fixed to the button 20. The piston shaft 17 is connected to a first piston 16 at one end. When the first piston 16 moves inward, it pressurizes the hydraulic oil. A third fixing block 21 is fixedly connected to the bottom of the outer ring of the rear column 1. A hydraulic oil groove 14 is opened inside the third fixing block 21. The hydraulic oil groove 14 stores hydraulic oil to facilitate braking of the universal wheel 25. A second piston 22 is slidably connected to the inner wall of the third fixing block 21, and the other side of the second piston 22 is slidably connected to the hydraulic oil groove 14. A brake block 23 is fixedly connected to one side of the second piston 22. The pressurized hydraulic oil pushes the second piston 22 and the brake block 23 to move, so that the brake block 23 can contact the universal wheel 25. The outer ring of the brake block 23 is slidably connected to the third fixing block 21.

[0038] Working principle: When braking is required, pressing button 20 compresses the hydraulic oil in the hydraulic oil tank 14 via piston shaft 17, causing the first piston 16 to compress the hydraulic oil. This compression causes the second piston 22 in the third fixed block 21 to move forward. The second piston 22 then moves the brake block 23, disengaging it from the caster 25. Friction between the caster 25 and the brake block 23 stops the caster 25 from moving, thus quickly and easily stopping its rotation. Releasing button 20 compresses the first piston 26. The second spring 19 returns the button 20 to its original position. When folding is required, first take out the cushion 26, then press the buckle 5 to press it, so that the buckle 5 enters the interior of the thin rod 4. By pushing the pillars on both sides inward, the thin rod 4 is fully inserted into the interior of the thick rods 3 on both sides. Then the first spring 6, which is compressed, causes the buckle 5 to pop out at the thick rod 3 to fix the thin rod 4. At the same time, after the second connecting rod 8 is stressed, it moves inward through the first hinge 9, and the folding plate 11 moves upward through the second hinge 10, thereby completing the folding of the device.
