The length of the support rod 5 can be adjusted according to actual needs, for example, through threaded connection or plug-in connection to achieve a telescopic design. The choice of the moving wheels 6 is also important. The front moving wheels 6 can be omnidirectional wheels for easy movement in different directions; while the rear moving wheels 6 can be directional wheels to ensure the stability of the walking aid when moving forward. The diameter and material of the moving wheels 6 also need to be carefully selected. Common materials include rubber and nylon, which can both absorb shock and prevent slippage.

[0051] The handrail 1 and support rod 5 are connected by a pivot, and an unlocking lever 7 is installed between them to control the relative state between the handrail 1 and support rod 5. When it is necessary to fold or unfold the walking aid, simply pull the unlocking lever 7 to easily complete the operation. In addition, the handrail 1 is equipped with a fastener 501, and the support rod 5 is equipped with a fixing pin 502; the fastener 501 and the fixing pin 502 are connected by a snap-fit ​​mechanism. This design not only facilitates storage and carrying but also improves the portability of the walking aid.

[0052] The first connecting rod 3 and the second connecting rod 4 are connected by a pivot. The upper end of the first connecting rod 3 is connected to the handrail 1 through the first buckle 8. The first buckle 8 is used to control the fixing and loosening of the first connecting rod 3 and the handrail 1. The upper end of the second connecting rod 4 is connected to the handrail 1 through the second buckle. The second buckle is used to control the fixing and loosening of the second connecting rod 4 and the handrail 1.

[0053] Specifically, the first connecting rod and the second connecting rod are connected by a pivot, so relative rotation between the first connecting rod and the second connecting rod is possible. The first connecting rod and the second connecting rod are connected to the handrails by the first buckle and the second buckle, respectively, allowing the user to adjust the clamping angle when not in use according to actual needs. This not only further improves the applicability of the walking aid, but also allows the two handrails to be placed together when not in use, thereby reducing the space occupied by the walking aid when stored.

[0054] The implementation principle of this embodiment is as follows:

[0055] By adding a support assembly with casters 6, the mobility and portability of the walking aid are significantly improved. Users can easily move the walking aid in various indoor or outdoor settings, which is especially crucial in hospitals, homes, or other public places. Furthermore, the retractable design of the support rod 5 and the quick-release mechanism between the handrail 1 and the support rod 5 allow the walking aid to be quickly folded and stored when not in use, saving space. In summary, this embodiment not only enriches the functionality of the walking aid but also greatly facilitates daily use, further enhancing the product's market competitiveness.

[0056] Example 4

[0057] The difference between this embodiment and the previous embodiment is the addition of a connecting assembly between the front and rear support rods 5. Specifically, the two support rods 5 are connected by a connecting assembly, which can be one or more connecting rods.

[0058] Specifically, the main function of the connecting assembly is to enhance the connection strength between the front and rear support rods 5, preventing separation during movement. The connecting rods can also be made of aluminum alloy or steel to ensure sufficient strength. The number and layout of the connecting rods can be adjusted according to actual needs, such as using a cross-arrangement or a parallel arrangement.

[0059] The implementation principle of this embodiment is as follows:

[0060] By adding a connecting component between the front and rear support rods 5, the overall stability and reliability of the walking aid are further improved. Especially when used on uneven terrain, the connecting component effectively prevents the support rods 5 from detaching, ensuring the walking aid is always in a safe working state. In summary, this embodiment not only optimizes the structural design of the walking aid but also significantly improves its performance in complex environments, further meeting diverse needs.

[0061] The above description is merely a specific embodiment of this application, enabling those skilled in the art to understand or implement this application.
