As shown in
In use, when transporting items smaller than the size of the storage basket 3, the items are placed in the accommodation space 2 formed by the first storage basket 4 and the second storage basket 5. When transporting items larger than the size of the storage basket 3, the fixing effect of the fixing mechanism is removed, the second connecting rods 7 are slid inside the first connecting rods 6, so that the second storage basket 5 is located in the first storage basket 4, the height of the storage basket 3 is thereby lowered, and the items are stacked above the storage basket 3. Since the height of the storage basket 3 is reduced, more space can be used to place large items, and it avoids from disassembling the storage basket or storage bag in the prior art and is easy to use.
More importantly, when transporting items, the second storage basket 5 is located in the first storage basket 4, it lowers the height of the storage basket 3, and two spaces are formed, one is formed by the storage basket. 3, the other is the space above the storage basket 3. Therefore, when transporting items, the user can first place small items in the accommodation space 2, and then place large items in the space above the storage basket 3, it avoids the problem of small items falling, and enables simultaneous transportation of items smaller than the size of the storage basket 3 and items larger than the size of the storage basket 3.
It should be noted that in the present disclosure, the side walls of the first storage basket 4 and the second storage basket 5 may be made of horizontally and vertically staggered side bars with intervals, or the side walls may also be made of sealed plates.

In this embodiment, the support frame 1 is of a telescopic/retractable structure. When the shopping trolley is not in use, the telescopic structure is used to lower the height of the support frame 1 so that the second storage basket 5 is located in the first storage basket 4, the height of the shopping trolley is reduced as a whole, saving space. When using the shopping trolley, the height of the support frame 1 can be adjusted according to the size of large items, thereby facilitating the transportation of large items. The telescopic structure refers to the lift rods of the luggage case in the prior art.

In this embodiment, as shown in
When this embodiment is in use, the folding part is used to fold the second storage basket 5, thereby reducing the height of the second storage basket 5. After the height of the second storage basket 5 is reduced, two spaces are formed, one is the accommodation space 2 formed by the lowered second storage basket 5 and the first storage basket 4, and the other is the space between the second storage basket 5 and the second connecting rods 7. When transporting items, small items are placed in the accommodation space 2 and large items are placed above the second storage basket 5, thereby realizing simultaneous transportation of items smaller than the size of the storage basket 3 and items larger than the size of the storage basket 3. The second connecting rods 7 restrict the movement of large items, thereby preventing the problem of becoming unstable during transportation when large items are stacked above the second storage basket 5.

In this embodiment, the support frame 1 is of a telescopic/retractable structure. When the shopping trolley is not in use, the telescopic structure is used to lower the height of the support frame 1 so that the second storage basket 5 is located in the first storage basket 4, the height of the shopping trolley is reduced as a whole, saving space. When using the shopping trolley, the height of the support frame 1 can be adjusted according to the size of large items, thereby facilitating the transportation of large items. The telescopic structure refers to the lift rod of the luggage case in the prior art.
A shopping trolley includes a support frame 1 and a storage basket 3 connected to the support frame 1 and forming an accommodation space 2 with the support frame 1. The storage basket 3 includes a first storage basket 4 and a second storage basket 5 located above the first storage basket 4. The second storage basket 5 can be placed in the first storage basket 4. The first storage basket 4 and the second storage basket 5 are slidingly connected through the adjustment mechanism, the adjustment mechanism is provided with a fixing mechanism for fixing the positions of the first storage basket 4 and the second storage basket 5.
The adjustment mechanism includes first connecting rods 6 and second connecting rods 7 slidably provided in the first connecting rods 6. Specifically, the first connecting rod 6 is provided with a first opening, and the second connecting rod 7 is located in the first opening. There is a distance of 2 mm between the side wall of the second connecting rod 7 and the side wall of the first opening. Two ends of the first connecting rod 6 are connected to the top and bottom of the first storage basket 4 respectively, and the two ends of the second connecting rod 7 are respectively connected to the top and bottom of the second storage basket 5.
The shape of the first storage basket 4 and the second storage basket 5 is cylindrical, the side wall of the first connecting rod 6 is connected to the inner side wall of the first storage basket 4, and the side wall of the second connecting rod 7 is connected to the outer side wall of the second storage basket 5.
In this embodiment, as shown in
When this embodiment is used, the usage method is the same as that of Embodiment 1. The difference is that the storage basket formed by the first storage basket 4 and the second storage basket 5 has a circular shape to avoid the edges and corners of a cubic storage basket from causing collision to the user.
In this embodiment, as shown in
In this embodiment, the support frame 1 is of a telescopic/retractable structure. When the shopping trolley is not in use, the telescopic structure is used to lower the height of the support frame 1 so that the second storage basket 5 is located in the first storage basket 4, the height of the shopping trolley is reduced as a whole, saving space. When using the shopping trolley, the height of the support frame 1 can be adjusted according to the size of large items, thereby facilitating the transportation of large items. The telescopic structure refers to the lift rod of the luggage case in the prior art.
