Description

Technical Field

[0001] This utility model relates to the field of walking aid technology, specifically a walking aid with adjustable seat height. Background Technology

[0002] Walking aids, as an important type of assistive mobile device, are widely used by the elderly, post-operative rehabilitation patients, and people with mobility impairments, aiming to provide stability and expand the user's range of motion. With increasing user demand for multifunctionality, walking aids with integrated seats are gradually becoming the mainstream design, serving both as walking aids and temporary seating for rest.

[0003] During the use of walking aids, the height of the walking aid can be changed according to the user's needs. However, when changing the height, only the bobbins are used to fix it. Over time, the surface of the bobbins will wear down, which reduces the lifespan of the bobbins and also reduces the safety of the walking aid during use. Utility Model Content

[0004] The purpose of this invention is to provide a walking aid with an adjustable seat height to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model proposes a walking aid with adjustable seat height, including a walking aid body, the walking aid body including a seat cushion, support mechanisms on both sides of the seat cushion, and a splitting mechanism on the top of the support mechanism.

[0006] The support mechanism includes a frame connected to both sides of the seat cushion. Multiple foot tubes are inserted through the bottom of the frame. A first sleeve is fixedly connected to the top of the outer wall of each foot tube. A first support plate is fixedly connected between every two opposing first sleeves. An internally threaded sleeve is fixedly connected to the bottom of each of the two first support plates. A threaded rod is threadedly connected to the inner wall of each of the two internally threaded sleeves. A sleeve is rotatably connected to one end of each of the two threaded rods. A top plate is fixedly connected to the bottom of each of the two sleeves. An insert plate is fixedly connected to the top of the top plate. A knob is fixedly connected to the other end of each of the two threaded rods.

[0007] In one example, limit rods are fixedly connected to both sides of the bottom of the two top plates, and limit holes are opened on both sides of the top of the two first support plates, with the limit rods interlocking with the inner walls of the limit holes.

[0008] In one example, a second sleeve is fixedly connected to both sides of the bottom of the two frames, and a second support plate is fixedly connected between the two second sleeves. The top of the second support plate has a strip hole, and the position of the insert plate is directly opposite the position of the strip hole.

[0009] In one example, the splitting mechanism includes multiple mounting holes formed on the outer wall of the frame, and each foot tube has a movable connecting bracket with a ball bearing on its outer wall, the ball bearing being interlocked with the inner wall of the mounting hole.

[0010] In one example, each foot tube has a fixed ring on both sides of its inner wall, and each fixed ring has a spring embedded in its inner wall. One end of the spring has a fixed rod, and the other side of the jumping ball is movably connected to one side of the fixed rod.

[0011] In one example, the outer wall of each of the fixed rods is engaged with a retaining ring, and the inner wall of the retaining ring is fitted onto the outer wall of the bob.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] A first support plate is provided between every two opposing foot tubes. The bottom of the first support plate has an internally threaded sleeve, the inner wall of which has a threaded rod, and the top of the threaded rod has a top plate. As the threaded rod rotates, it rises along the threaded trajectory. One end of the threaded rod has a sleeve that slides against the outer wall of the threaded rod, preventing the top plate from rotating during rotation. The top plate acts as a support, providing secondary reinforcement to the frame and foot tubes, preventing adjustments based on height. This enhances stability over extended use, improves the lifespan of the walking aid, and increases its durability for different users. Limiting rods are located at the bottom of the two top plates, interlocking with the top of the first support plate for added stability. Insert plates are located at the top of the two top plates, acting as positioning components to prevent deviation.

[0014] The height of the walker can be adjusted by the mounting holes on the frame and the ball bearings on the foot tubes. During long-term use, the ball bearings are fixed by the compression of the fixing rod by the spring and by the engagement of the retaining ring with the fixing rod. The inner diameter of the retaining ring is smaller than the maximum outer diameter of the ball bearing, which can prevent the ball bearings from falling off during use and make them easier to replace, thus improving the practicality of the device.
