[0035] The present application is further described below in detail through specific embodiments in conjunction with the accompanying drawings.

[0036] Example 1

[0037] A pull-type folding shopping cart, such as Figure 1 and Figure 2 As shown, it includes a box body 1, and a plurality of universal wheels 11 are provided at the bottom of the box body 1. The box body 1 includes side panels 2, a bottom panel 3, and a top panel 4. A triangular wheel frame 12 is also provided at the bottom of the box body 1. A rotating shaft is provided between the triangular wheel frames 12. The triangular wheel frame 12 is rotatably connected to the box body 1 by means of the rotating shaft. A sliding wheel 121 is rotatably provided on each triangle of the triangular wheel frame 12. In specific implementation, two universal wheels 11 are provided at one end of the width direction of the box body 1, and two triangular wheel frames 12 and a rotating shaft are provided at the other end of the width direction of the box body 1. The two universal wheels 11 are respectively provided at the two ends of the length direction of the box body 1, and the two triangular wheel frames 12 are also respectively provided at the two ends of the length direction of the box body 1. Therefore, at least two wheels of the triangular wheel frame 12 can play a driving role, and the universal wheels 11 play a steering effect, thereby improving the convenience during use.

[0038] like Figure 1 and Figure 2 As shown, the top panel 4 is hinged to the side panel 2 and is restricted when rotating toward the inside of the box body 1. The bottom panel 3 is also hinged to the side panel 2 and is restricted when rotating toward the outside of the box body 1. The side panel 2 includes two fixed panels 21 and four folding panels 22. The folding panels 22 are arranged at both ends of the length direction of the box body 1 and two are arranged at each end. The fixed panels 21 are arranged at both ends of the width direction of the box body 1. One side of the folding panel 22 is hinged to the top panel 4, and the other side of the folding panel 22 is hinged to the fixed panel 21.

[0039] like Figure 1 and Figure 2 As shown, a telescopic handle 23 is fixedly provided on the side panel 2, and the telescopic handle 23 can be positioned after being extended. In specific implementation, the telescopic handle 23 adopts the telescopic handle 23 often used in luggage boxes in the prior art, which can be convenient when lifting and pulling.

[0040] like Figure 1 and Figure 2 As shown, each folding plate 22 is provided with a through slot 221, which passes through the folding plate 22 and is provided on a side of the folding plate 22 close to the top plate 4. In a specific implementation, when operating the folding plate 22, a hand can be placed on the through slot 221 to push, thereby improving the convenience of operating the folding plate 22.

[0041] like Figure 1 and Figure 2 As shown, the fixed plate 21 on one side is higher than the fixed plate 21 on the other side, and the top plate 4 can abut the top of the fixed plate 21 when rotating. In a specific implementation, the top plate 4 can interfere with the fixed plate 21 when rotating, thereby limiting the rotation range. Due to the different heights of the fixed plates 21, the top plate 4 can be further reduced from being uneven after the box body 1 is closed, thereby improving stability during use.

[0042] like Figure 1 and Figure 2 As shown, the bottom of the fixed plate 21 is also provided with a support plate 211, which is used to abut the bottom plate 3 from the bottom side. A clearance groove 31 is provided at the position of the bottom plate 3 corresponding to the support plate 211, and the clearance groove 31 is provided through the bottom plate 3. In specific implementation, the support plate 211 does not block the clearance groove 31, but can abut and support the bottom plate 3, allowing the support plate 211 to extend through the clearance groove 31 to grasp the bottom plate 3, and then the bottom plate 3 can be flipped up from the clearance groove 31, thereby improving the convenience of flipping the bottom plate 3.

[0043] like Figure 1 and Figure 2 As shown, the side panels 2 are provided with a plurality of snap-on plates 24, each of which is provided with a plurality of snap-on slots 241. The bottom panel 3 is provided with snap-on members 32 corresponding to the snap-on slots 241. The snap-on members 32 are configured to snap into the snap-on slots 241. In a specific implementation, the snap-on plates 24 are provided on the side panels 2 and are snap-oned together by the snap-on members 32. This can reduce the possibility of the bottom panel 3 bouncing up when loaded with items and affecting the items, thereby improving stability during use.

[0044] like Figure 1 and Figure 2 As shown, protrusions 41 are provided on both sides of the top plate 4, and the protrusions 41 extend toward the length direction of the box body 1. In specific implementation, when the top plate 4 is turned up, the protrusions 41 can assist, thereby further increasing the convenience of turning the top plate 4.

[0045] Working principle: When not in use, the panels are folded and stored, thereby reducing the space occupied by the box body 1 and reducing the inconvenience of storage. When in use, the box body 1 can be assembled and used, and can be moved by pulling the telescopic handle 23.

[0046] Example 2

[0047] like Figure 3As shown, the main difference between Example 2 and Example 1 is that in Example 2, a brake lever 25 is further provided at the bottom of the fixed plate 21. The bottom of the brake lever 25 is provided with a rubber block 251 for contacting the ground, and the brake lever 25 is slidably connected to the top plate 4. A blocking piece 26 is also provided at the bottom of the fixed plate 21, corresponding to the brake lever 25. The blocking piece 26 is rotatably connected to the fixed plate 21, and a torsion spring is provided at the rotational connection. The torsion spring has a tendency to drive the blocking piece 26 in a direction that blocks the brake lever 25. In practice, the rubber block 251 at the bottom of the brake lever 25 creates friction with the ground, thereby providing a braking effect and reducing the possibility that the box 1 cannot stop. When braking is not required, the brake lever 25 is retracted, and the blocking piece 26 blocks the brake lever 25.

[0048] Working principle: The basic working principle is the same as that of the first embodiment, but a brake lever 25 is added to reduce the situation where the box body 1 cannot stop.

[0049] The above are preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
