Description

Technical Field

[0001] The utility model relates to a walker, in particular to a walker with good stability. Background Art

[0002] A rollator is a four-wheeled vehicle that can be pushed by hand. When the user has difficulty walking, he can push the rollator while walking and use the rollator to maintain body balance while walking. It is widely used to assist the elderly or patients to walk. Because the people who use the rollator are all elderly or patients, the load-bearing performance and stability of the rollator are very important.

[0003] The frames of existing rollators can be divided into one-piece or spliced ​​frames. The one-piece frame is generally in a three-pronged shape, with the main force concentrated at the intersection, poor load-bearing performance, and easy to break due to overload; while the spliced ​​frame is made of multiple frame tubes, and the splicing points are prone to loosening after long-term use, affecting the stability of the rollator.

[0004] In order to overcome the deficiencies of the prior art, the utility model provides a walker with good stability.

[0005] The technical solution adopted by the utility model to solve its technical problems is:

[0006] A walking aid with good stability comprises a handlebar, a wheel body, and two frames arranged opposite to each other. The two frames are connected by a connecting structure. The frames are in a triangular shape. The handlebar is arranged above the frames, and the wheel body is arranged below the frames.

[0007] Furthermore, the frame includes a front rod, a rear rod and a connecting rod, the handle is provided at the upper end of the front rod, the wheel body is provided at the lower end of the front rod, the upper end of the rear rod is connected to the middle part of the front rod, the wheel body is provided at the lower end of the rear rod, and the two ends of the connecting rod are respectively connected to the lower parts of the front rod and the rear rod.

[0008] Furthermore, the rear rod is an arc-shaped tube convex upward.

[0009] Furthermore, the connecting rod is an upwardly convex arc tube.

[0010] Furthermore, the connection structure is a fork-type folding structure.

[0011] Furthermore, a seat cushion is arranged above the connecting structure, and both ends of the seat cushion are respectively connected to the frame.

[0012] Furthermore, the handle is connected to the frame via a telescopic structure, and the telescopic structure can adjust the height of the handle.

[0013] Furthermore, the telescopic structure includes a long rod and a locking switch, one end of the long rod is fixedly connected to the handle, and the other end of the long rod is slidably connected to the frame. The locking switch is arranged on the upper part of the frame and can limit the sliding of the long rod.

[0014] The beneficial effects of the utility model are as follows: compared with the prior art, the frame of the utility model is in a triangular shape. Such a design not only improves the integrity and structural stability of the frame, but also makes the appearance simple and beautiful, and has good load-bearing performance; by providing a fork-type folding structure, the utility model can be folded and stored, and is more convenient to use; by providing a seat cushion, the utility model can be pushed and sat on, and has more complete functions and is more user-friendly; by providing a telescopic structure, the utility model can adjust the height of the handlebar as needed.

[0018] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0019] Reference Figure 1 , Figure 2 A walker with good stability comprises a handlebar 1, a wheel body 2, and two frames 3 arranged opposite to each other. The two frames 3 are connected by a connecting structure. Specifically, the two frames 3 are symmetrically arranged, and the frames 3 on both sides are connected by a fixed or foldable structure. The frame 3 is in a triangular shape, which has better structural stability and can avoid the force being concentrated on the intersection of the frame tubes, so that the load-bearing performance of the frame 3 is higher. The handlebar 1 is arranged above the frame 3, and the wheel body 2 is arranged below the frame 3. Compared with the prior art, the frame 3 of the utility model is in a triangular shape. Such a design not only has good integrity and structural stability of the frame 3, but also has a simple and beautiful appearance and good load-bearing performance.

[0020] Furthermore, the frame 3 includes a front rod 31, a rear rod 32 and a connecting rod 33. The upper end of the front rod 31 is provided with the handlebar 1, and the lower end of the front rod 31 is provided with the wheel body 2. The upper end of the rear rod 32 is connected to the middle of the front rod 31, and the lower end of the rear rod 32 is provided with the wheel body 2. The two ends of the connecting rod 33 are respectively connected to the lower parts of the front rod 31 and the rear rod 32. In the design of this embodiment, the handlebar 1 is located in the middle of the front and rear wheels, and the front and rear wheels are evenly stressed and not prone to tipping.

[0021] Further, the rear rod 32 is an arc-shaped tube convex upward. With such a design of this embodiment, the load-bearing performance of the rear rod 32 is better.

[0022] Furthermore, the connecting rod 33 is an arc-shaped tube convex upward. With such a design of this embodiment, the connecting rod 33 has better load-bearing performance and a higher height from the ground, so that this embodiment is not easily bumped by obstacles and hindered from walking.

[0023] Further, the connection structure is a fork-type folding structure 4. The fork-type folding structure 4 includes a fork-type hinge rod and a limiter. The limiter can limit the movement of the fork-type hinge rod. By providing the fork-type folding structure 4, this embodiment can be folded and stored, and is more convenient to use.

[0024] Furthermore, a seat cushion 5 is arranged above the connection structure, and both ends of the seat cushion 5 are respectively connected to the frame 3. The seat cushion 5 is arranged in this embodiment, which can be pushed or sat on, has more complete functions and is more humane.

[0025] Furthermore, the handlebar 1 is connected to the frame 3 through a telescopic structure, and the telescopic structure can adjust the height of the handlebar 1. The telescopic structure includes a long rod 6 and a locking switch 7, one end of the long rod 6 is fixedly connected to the handlebar 1, and the other end of the long rod 6 is slidably connected to the frame 3. The locking switch 7 is arranged on the upper part of the frame 3 and can limit the sliding of the long rod 6. In this embodiment, the height of the handlebar 1 can be adjusted as needed.

[0026] The above implementation modes cannot limit the protection scope of the present invention. The equivalent modifications and changes made by those skilled in the art without departing from the overall concept of the present invention are still within the scope of the present invention.
