Description

Technical Field

[0001] The present application relates to the technical field of daily-use products, and in particular to a household shopping cart. Background Art

[0002] As an indispensable auxiliary tool in the daily life of modern families, household shopping carts are widely used in various scenarios such as supermarket shopping, moving and transporting, and household storage. With the accelerated pace of life, consumers' demand for household shopping carts is growing, especially the requirements for their portability, load-bearing capacity and structural stability are constantly increasing.

[0003] However, existing household shopping carts generally have contradictions in design and function. On the one hand, in pursuit of compactness and lightness, product design often sacrifices the stability of the body structure, resulting in easy shaking during dragging and limited load-bearing capacity; on the other hand, although some products have a stable structure, they are large in size, cumbersome to drag, and inconvenient for daily use and storage. In particular, traditional detachable shopping carts are often designed with multiple unlocking buckles, which are cumbersome to operate and affect the user experience. Utility Model Content

[0004] The purpose of this application is to provide a household shopping cart, which can improve the above-mentioned problems.

[0005] The embodiment of the present application is implemented as follows:

[0006] The present application provides a household shopping cart, which comprises: a trailer and at least one foldable storage box, wherein the foldable storage box is temporarily fixed to the vehicle board of the trailer; the foldable storage box comprises a bottom plate, a collar, a cover plate, a front plate, a right plate, a back plate and a left plate vertically arranged on the bottom plate; when in use, the front plate, the right plate, the back plate and the left plate are connected in sequence to form a barrel-shaped side wall to enclose a storage space; the annular edge of the barrel-shaped side wall facing away from the bottom plate is wrapped by the collar; the cover plate is placed on the side of the collar facing away from the bottom plate.

[0007] It can be understood that the present application discloses a household shopping cart, including a trailer and at least one foldable storage box. The foldable storage box is formed by sequentially connecting a front panel, a right panel, a back panel and a left panel arranged on a bottom plate, and a sleeve is wrapped on the barrel-shaped side wall to replace the latch structure to fix two adjacent panels, which not only greatly enhances the strength of the structure and makes the box more stable, but also simplifies the product structure, reduces the mold cost, and simplifies the operation steps.

[0008] In an optional embodiment of the present application, the left panel and the right panel are both connected to the bottom panel via hinges, the front panel includes a first front sub-panel and a second front sub-panel connected to each other via hinges, the back panel includes a first back sub-panel and a second back sub-panel connected to each other via hinges, and the first front sub-panel and the first back sub-panel are fixed to the bottom panel; in a folded state, the left panel, the right panel, the second front sub-panel and the second back sub-panel are all folded into the storage space via hinges, the ring wraps the edges of the first front sub-panel and the first back sub-panel away from the bottom panel, and the cover plate is placed on the side of the ring away from the bottom panel.

[0009] It can be understood that the household shopping cart disclosed in the present application has two states. When in use, the front panel, right panel, back panel and left panel can be opened to form a barrel-shaped side wall to enclose a storage space for storing items; when in a folded state or idle state, the left panel, right panel, second front sub-panel and second back sub-panel can be folded to avoid occupying space. Therefore, the present application solves the contradiction between the existing household shopping carts in terms of space usage and bulkiness in towing / storage.

[0010] In an optional embodiment of the present application, a first annular groove is provided on the vehicle plate of the trailer, and a first annular protrusion is provided on the surface of the bottom plate facing away from the barrel-shaped side wall; the first annular groove matches the structure of the first annular protrusion.

[0011] It can be understood that when the foldable storage box needs to be placed on the trailer, it is only necessary to align the first annular protrusion at the bottom of the foldable storage box with the first annular groove on the trailer and clip the foldable storage box onto the trailer board; when the foldable storage box needs to be removed from the trailer, it is only necessary to directly remove it. The foldable storage box does not require any buckle and latch structure to be taken in and out, which greatly reduces the amount of operation.

[0012] In an optional embodiment of the present application, a second annular groove matching the first annular protrusion is also provided on the annular edge; the bottom plate of one of the foldable storage boxes can be snapped onto the annular edge of another of the foldable storage boxes.

[0013] It can be understood that the storage boxes on the trailer can be stacked, and the bottom of the upper storage box can cooperate with the ring of the lower storage box to achieve stacking; the stacking of the storage boxes allows the shopping cart to load multiple storage boxes at a time, increasing the carrying capacity of goods, and at the same time the storage boxes can be placed more stably.

[0014] In an optional embodiment of the present application, a surface of the collar facing the annular edge is also provided with a second annular protrusion matching the second annular groove.

[0015] It can be understood that the second annular protrusion is provided on the collar, which can better match the barrel-shaped side wall, thereby fixing the front panel, the right panel, the back panel and the left panel.

[0016] In an optional embodiment of the present application, the structure corresponding to the second annular groove on the second front sub-panel is a third groove; the edge of the first front sub-panel away from the bottom plate is also provided with a fourth groove that is identical to the third groove; the structure corresponding to the second annular groove on the second back sub-panel is a fifth groove; the edge of the first back sub-panel away from the bottom plate is also provided with a sixth groove that is identical to the fifth groove.

[0017] It can be understood that, in the folded state, the ring provided with the second annular protrusion can also better match the edges of the first front sub-panel and the first back sub-panel away from the bottom plate to play a fixing role.

[0018] In an optional embodiment of the present application, the pull rod of the trailer is connected to the vehicle plate via a hinge, and a second groove is further provided on the vehicle plate for accommodating the pull rod.

[0019] It can be understood that when in the folded state, the trailer pull rod can also be stored in the second groove of the vehicle plate, further reducing the space occupied by the household shopping cart when it is idle, making it easier to place; at the same time, the packaging volume is reduced and the cost is reduced.

[0020] In an optional embodiment of the present application, a first fastener is provided on the second front sub-panel, and a second fastener is provided at the end of the pull rod facing away from the vehicle panel, the first fastener and the second fastener match, and the end of the pull rod can be locked or unlocked to the foldable storage box.

[0021] In an optional embodiment of the present application, the pull rod is a double pull rod structure, and the second buckle is arranged on a connecting piece connecting the two pull rods. It can be understood that the double pull rod can enhance the force strength when towing the trailer and make it easier to turn.

[0022] In an optional embodiment of the present application, the bottom of the trailer's vehicle deck is equipped with at least four universal casters, wherein at least two universal casters close to the trailer's pull rod have a braking function.

[0023] Beneficial effects:

[0024] The present application discloses a household shopping cart, including a trailer and at least one foldable storage box.
