[0023] The present invention will now be further described with reference to the accompanying drawings and specific implementation methods.

[0024] This embodiment provides a wheelchair push ring 1 with thumb protection function, such as Figures 1 to 5 As shown, the wheelchair includes wheels arranged on both sides, a push ring 1 is fixedly provided on the outer side of the wheel, and the circumference of the push ring 1 is concave along the center direction of the push ring 1 to form a groove 2 for the thumb to be placed, and the groove 2 is located between the push ring 1 and the outer side of the wheel.

[0025] The circumference of the push ring 1 of this embodiment extends inward along the center of the push ring 1 to form a groove 2 having a first extension 21. This groove 2 is located between the push ring 1 and the outside of the wheel, providing space for the thumb. The first extension 21 can be customized in length and shape according to the user's needs, so that the shape of the groove 2 can adapt to the thumb shape and usage habits of different users, resulting in a user-friendly design. When the user's palm and four fingers are placed on the circumference of the push ring 1, the thumb will naturally rest in the groove 2, preventing the thumb from reaching the gap between the push ring 1 and the wheel and contacting the outside of the wheel. The simple structure effectively reduces the risk of thumb injury and improves user safety.

[0026] like Figures 1 to 4 As shown, the edge of the groove 2 near the outside of the wheel extends toward the circumferential direction of the push ring 1 to form a convex wall 3. The groove 2 of this embodiment extends toward the circumferential direction of the push ring 1 at the edge near the outside of the wheel to form a convex wall 3 with a second extension portion 31. The convex wall 3 extends outward along the circumferential direction of the push ring 1, so that the groove 2 and the outer surface of the convex wall 3 form a curved surface, which is more comfortable for the user to place the thumb. The diameter of the convex wall 3 at the edge of this embodiment is larger than the diameter of the push ring 1, further ensuring that the thumb will not come into contact with the outside of the wheel, thereby improving the safety of use. The push ring 1 of this embodiment is made of high-strength, wear-resistant material, which can ensure durability and stability. The groove 2 and the convex wall 3 are made of rubber or silicone material, but are not limited to this. They have a certain strength and can provide a comfortable touch.

[0027] like Figure 5 As shown, in this embodiment, the angle between the connection point of the groove 2 on the push ring 1 and the horizontal plane is between 0-45 degrees. The user can adjust the angle between the bottom of the groove 2 and the horizontal plane according to actual conditions. Specifically, it can be set to an angle between the bottom and the horizontal plane within a range of 45 degrees above and below, thereby meeting the usage needs of different users. Accordingly, the extension angle and extension length of the convex wall 3 can also be adjusted, and the design is humanized.

[0028] like Figure 5 As shown, the distance B between the convex wall 3 and the outer side of the push ring 1 in this embodiment is 25-50 mm. This distance can better adapt to the thickness of the user's palm and facilitate the placement of the user's hand and thumb, but is not limited to this. In other embodiments, the distance between the wall and the outer side of the push ring 1 is adjusted.

[0029] like Figure 3 and Figure 4 As shown, the smooth transition between the groove 2 and the convex wall 3 in this embodiment reduces friction and discomfort when the thumb is placed at the junction of the groove 2 and the convex wall 3. This also makes the groove 2 more aesthetically pleasing and facilitates cleaning later. This allows the user to maintain hand comfort and reduce hand fatigue when pushing the wheelchair for a long time.

[0030] like Figure 2 As shown, the thickness of the convex wall 3 in this embodiment is less than that of the push ring 1. While ensuring a certain strength, it can reduce the overall weight of the push ring 1, allowing the user to push the wheelchair easily and reduce physical exertion. At the same time, the reduction in material also helps to reduce production and processing costs.

[0031] Furthermore, in this embodiment, the groove 2 and the push ring 1 are integrally formed, and the integral forming process is conducive to simplifying the production process and improving the aesthetics of the product. In this example, the convex wall 3 and the groove 2 are also integrally formed, which enhances the strength and stability of the overall structure.

[0032] like Figures 1 to 3 As shown, the push ring 1 is provided with a connecting rod 4 connected and fixed to the wheel. In this embodiment, the number of connecting rods 4 is six, but not limited thereto. The connecting rods 4 are fixedly connected to the wheel hub so that when the push ring 1 rotates, the wheel can be driven to rotate through the connecting rods 4.

[0033] Furthermore, the connecting rod 4 of this embodiment is fixed to the wheel by bolts, which has a simple structure and is easy to assemble and disassemble. In other embodiments, other connection methods can also be used for fixing.

[0034] like Figures 1 to 3 As shown, the connecting rods 4 of this embodiment are evenly distributed, which can improve the aesthetics while ensuring that the connecting rods 4 are evenly stressed. In other embodiments, the positions of the connecting rods 4 can also be adjusted.

[0035] The use process of this utility model is as follows:

[0036] The push ring 1 is fixed to the wheel through the connecting rod 4. When the palm and four fingers of the user's hand are placed on the circumference of the push ring 1, the circumference of the push ring 1 is concave along the center direction of the push ring 1 to form a groove 2. Therefore, when the palm and four fingers cooperate to push the push ring 1, the user's thumb will naturally be placed on the groove 2.

[0037] The directional terms mentioned in this specification are defined relative to the structures shown in the drawings. They are relative concepts and may vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive terms.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the design of this case. Any equivalent changes made based on the key design of this case shall fall within the scope of protection of this case.
