Description

Technical Field

[0001] This utility model relates to a folding shopping cart. Background Technology

[0002] Shopping carts are a common tool used by people when shopping, especially when carrying heavy items, where they offer great convenience. To facilitate storage, foldable shopping carts are now widely adopted.

[0003] For example, the folding storage box disclosed in Chinese patent documents [Application No. 201720541182.2] and the folding storage box [Application No. 201821853970.6] both adopt a method where the left and right side panels can be folded and the bottom plate and cover plate can be rotated and fitted together to achieve the overall folding of the shopping cart. In order to fix the left and right side panels when unfolded, the folding storage box in the above-mentioned patent documents adopts a fixing structure between the left and right side panels and the rear and front panels. This fixing structure is relatively complex and inconvenient to operate when folding. The aforementioned patent documents describe a folding storage box that uses locking sleeves on the foldable left and right side panels to secure it when unfolded. The U-shaped locking sleeves rely on thin walls on both sides to bear the force, resulting in low overall strength. Under significant stress, the thin walls on both sides are prone to deformation and damage. The left and right side panels are also easily deformed when unfolded, leading to an unstable structure after the shopping cart is unfolded. In addition, since the locking sleeves are on the outside, there is a possibility of the locking sleeves sliding and unlocking when items are stored or retrieved. For example, if clothing is caught on the corner of the locking sleeve and then pulled, the locking sleeve may slide and unlock. Utility Model Content

[0024] This utility model provides a folding shopping cart.

[0025] like Figure 1As shown, the folding shopping cart provided in this embodiment of the present invention includes a basket 10, the basket 10 including a bottom plate, a left side plate 13, a right side plate, a rear plate 12 and a front plate 11. The left side plate 13 and the right side plate each include a first folding plate 131 and a second folding plate 132. The first folding plate 131 and the second folding plate 132 are rotatably connected to the front plate 11 and the rear plate 12 respectively. The first folding plate 131 and the second folding plate 132 are snapped together by a rotating structure 20 installed on the second folding plate 132.

[0026] In this embodiment, the connection and disassembly between the first folding plate 131 and the second folding plate 132 can be achieved through the rotating structure 20, thereby improving user convenience.

[0027] In one embodiment, please refer to Figure 2 The rotating structure 20 includes a movable lock, which includes a mounting plate 21 and a retaining member 22 disposed on the mounting plate 21. The retaining member 22 has a retaining groove 23. A hollow frame 133 is disposed on the first folding plate 131. A stop protrusion 134 is provided on the inner top surface of the frame 133, protruding downwards. The stop protrusion 134 can be retained in the retaining groove 23. In this embodiment, when the first folding plate 131 rotates toward the second folding plate 132, since the lower end of the stop protrusion 134 has a first inclined surface that is inclined upwards, and the retaining member 22 has a second inclined surface that is parallel to the first inclined surface, the stop protrusion 134 can slide into the retaining groove 23 through the guiding effect of the first and second inclined surfaces. The first folding plate 131 and the second folding plate 132 are locked by the cooperation of the stop protrusion 134 and the retaining member 22, thus completing the assembly.

[0028] When disassembly is required, simply press down on the mounting plate 21 to disengage the stop protrusion 134 and the retaining member 22. Then, move the first folding plate 131 to separate the first folding plate 131 and the second folding plate 132. At this point, the mounting plate 21 can be returned to its original position by abutting against the spring 24 connected below it. Correspondingly, during installation, when the first and second inclined surfaces engage, the second inclined surface will press against the first inclined surface, causing the mounting plate 21 to move downwards as a whole. At this time, the spring 24 is compressed. When the stop protrusion 134 falls into the retaining groove 23, the spring 24 can move the mounting plate 21 upwards to its original position, thus locking the two together.

[0029] Please refer to Figure 3In another embodiment provided in this application, the rotating structure 20 includes a movable lock, which includes a mounting plate 21 and a blocking member 25 disposed on the mounting plate 21. A receiving cavity 26 is formed between the blocking member 25 and the mounting plate 21. In this embodiment, a hollow frame 133 is disposed on the first folding plate 131, and the frame 133 is disposed within the receiving cavity 26 so that the blocking member 25 blocks the frame 133. That is, in this embodiment, the movable lock can be modified to unlock by lifting and lock by pressing down. When pressed down, both the upper and lower sides of the frame 133 will be correspondingly engaged in the receiving cavity 26, achieving a limiting effect. By installing elastic pins on the movable lock, the elastic pins can extend and block the mounting plate 21 when it is lifted, preventing it from falling. During disassembly, simply pressing the elastic pins allows the mounting plate 21 to fall, thus separating the first folding plate 131 and the second folding plate 132.

[0030] Alternatively, in other embodiments, the blocking member 25 can be rotated, meaning the blocking member 25 is rotatably mounted on the mounting plate 21, and the mounting plate 21 has a knob connected to the blocking member 25. The blocking member 25 can be blocked or disengaged by rotating the knob.

[0031] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the concept of the present utility model and using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included in the patent protection scope of the present utility model.
