[0047] The embodiments of the present utility model are described below in conjunction with the drawings.

[0048] For the sake of convenience, Figure 1 and Figure 2A three-dimensional rectangular coordinate system is added, wherein the direction in which the X-axis is located is a first direction, i.e., the arrangement direction of the two sets of walking support frames 11, the direction in which the Y-axis is located is a second direction, i.e., the folding direction of the folding support frame 112, and the direction in which the Z-axis is located is a third direction, i.e., the arrangement direction of the walking wheel assembly 12 and the arm support assembly 111, which is also the direction of gravity.

[0049] Referring to Figure 1 The walking cart provided by the embodiment of the present disclosure comprises two sets of walking support frames 11, two sets of walking wheel assemblies 12, and a connecting assembly 13. The two sets of walking support frames 11 are arranged at intervals along a first direction. Each set of walking support frames 11 comprises an arm support assembly 111 and a folding support frame 112. The folding support frame 112 can be folded along a second direction. The folding support frame 112 is connected to the arm support assembly 111 at one end in a third direction. The two sets of walking wheel assemblies 12 are arranged at intervals along the first direction. The folding support frame 112 on each set of walking support frames 11 is connected to a corresponding set of walking wheel assemblies 12 at the other end in the third direction in an extendable manner. That is, the walking wheel assembly 12 and the arm support assembly 111 are arranged at intervals along the third direction and are arranged at opposite ends of the folding support frame 112, respectively. The connecting assembly 13 is arranged between the two sets of walking support frames 11. One end of the connecting assembly 13 is connected to a corresponding set of folding support frames 112 in the second direction.

[0050] In the walking cart described above, the two sets of walking wheel assemblies 12 assist walking and support the folding support frame 112. The folding support frame 112 supports the arm support assembly 111, and the arm support assembly 111 supports the user's arms, so as to better support the user and better assist the user in walking. The two sets of walking support frames 112 are connected and fixed by the connecting assembly 13, so as to make the structure of the walking cart more stable. At the same time, the folding support frame 112 is folded along the second direction, so as to reduce the volume of the walking support frame 11, facilitating the carrying and transportation of the walking cart. The length of the walking wheel assembly 12 extending out of the folding support frame 112 is adjusted, so as to adjust the overall height of the walking cart, facilitating the use of the walking cart by users of different heights, thereby improving the applicability of the walking cart. In this way, the folding design of the folding support frame 112 and the extendable structure between the walking wheel assembly 12 and the folding support frame 112 improve the applicability of the walking cart on the basis of improving the convenience of carrying and transporting the walking cart.

[0051] Referring to Figure 2In some embodiments, the folding support 112 comprises a hinge 1121, a first folding rod 1122 and a second folding rod 1123. The hinge 1121 is substantially in the shape of L. The hinge 1121 is sleeved and fixedly connected to one end of the first folding rod 1122. One end of the second folding rod 1123 is rotatably connected to the hinge 1121. The first folding rod 1122 and the second folding rod 1123 are folded or unfolded through the hinge 1121. A part of each set of walking wheel assembly 12 is telescopically connected to the other end of the first folding rod 1122. The other part of each set of walking wheel assembly 12 is telescopically connected to the other end of the second folding rod 1123.

[0052] In this way, the second folding rod 1123 is actuated by an external force to rotate one end of the second folding rod 1123 around the hinge 1121 to a predetermined angle, and the other end assembly of the second folding rod 1123 is away from the other end of the first folding rod 1122, so as to quickly unfold the folding support 112. The unfolded first folding rod 1122 and the other end of the second folding rod 1123 are placed on the ground, and the first folding rod 1122 and the second folding rod 1123 are both in an inclined state to achieve stable support. The second folding rod 1123 is actuated by an external force to rotate one end of the second folding rod 1123 around the hinge 1121, and the other end of the second folding rod 1123 is close to the other end of the first folding rod 1122, so as to quickly fold the folding support 112. The folding support 112 has a simple structure and is convenient to operate.

That is, the first walking member 121 is a part of the walking wheel assembly 12, and the second walking member 122 is the other part of the walking wheel assembly 12. Please refer to Figure 3 The first walking member 121 comprises a first telescopic rod 1211, a first adjusting member 1212 and a first walking wheel 1213. One end of the first telescopic rod 1211 is slidably inserted into the other end of the first folding rod 1122. The first adjusting member 1212 is used to fix the first telescopic rod 1211 slid to a predetermined position to the first folding rod 1122. The first walking wheel 1213 is connected to the other end of the first telescopic rod 1211. Figure 4 The second walking member 122 comprises a second telescopic rod 1221, a second adjusting member 1222 and a second walking wheel 1223.
