Description

Technical Field

[0001] This utility model relates to a shopping cart, and more particularly to a shopping cart whose lid can be hidden inside the box. Background Technology

[0002] The shopping cart includes a box with wheels at the bottom, a retractable handle, and an openable lid.

[0003] There are two ways to connect the lid to the box body; the first way is that after the lid is opened, the lid hangs on the outside of the box body.

[0004] The second type: After the lid is opened, it is stored inside the box. Specifically, a partition is set inside the box to form an inner cavity for the lid to be inserted. At the same time, sliding grooves are provided on both sides of the inner cavity, and a shaft is provided on each side of the lid. When the lid moves up and down, the shaft can slide in the sliding groove.

[0005] The problem is that the shaft connection structure is relatively small, and the lid is prone to detaching from the box body due to plastic wear, aging, deformation, etc. Utility Model Content

[0006] The technical problem this invention aims to solve is to provide a shopping cart with a reliable flip-up lid that can be hidden inside the box.

[0007] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a shopping cart in which the lid can be hidden in the box body, including a box body and a lid, wherein wheels are installed at the bottom of the box body;

[0008] The enclosure includes a bottom plate, a rear plate, a front plate, and two foldable side plates; a retractable pull rod is installed on the rear plate; the rear plate includes a rear base plate and two side bends, the side bends extending toward the front plate;

[0009] A barrier plate is connected to the two bent portions by a screw assembly to form a cavity that accommodates the box lid;

[0010] A rotating connection structure and a limiting structure are provided between the upper end of the side wall of the cavity and the bottom of the box cover;

[0011] The rotating connection structure allows the lid to be rotated 90 degrees and placed on the box body after it has been moved to the upper position of the cavity; the limiting structure prevents the lid from detaching from the box body.

[0012] A further preferred embodiment of this utility model is as follows: the barrier plate includes a plate body, side plates, and a connecting part. The side plates are vertically distributed on the side of the plate body, and the connecting part is located on the outside of the side plates. The connecting part and the bending part are fixed together by a plurality of screws.

[0013] A further preferred embodiment of this utility model is as follows: the rotating connection structure includes an elastic protrusion on the upper inner side of the side plate and grooves on the bottom of both sides of the box cover; the elastic protrusion faces the box cover inside the cavity, and the elastic protrusion is higher than the upper surface of the plate.

[0014] When the lid moves upward along the cavity, the groove of the lid falls into the elastic protrusion, and the lid can rotate 90 degrees around the elastic protrusion to cover the box body and close the box body's receiving cavity.

[0015] A further preferred embodiment of this utility model is as follows: the limiting structure includes a first limiting structure provided on the upper side of the plate and a second limiting structure provided on the bottom of the box cover.

[0016] A further preferred embodiment of this utility model is as follows: the first limiting structure consists of two protruding plates on the plate body, and the second limiting structure consists of a groove at the bottom of the box cover.

[0017] A further preferred embodiment of this utility model is as follows: the upper end of the side plate is provided with a central column and two side columns, and a gap is provided between the central column and the two side columns, and the elastic protrusion is arranged on the central column.

[0018] A further preferred embodiment of this utility model is as follows: the connecting part is provided with a plurality of first connecting posts, the bending part is provided with a plurality of second connecting posts, and the first connecting posts and the second connecting posts are fixed by screws.

[0019] A further preferred embodiment of this utility model is that, after the lid is closed, its outer wall surface and the top wall of each panel forming the box body are in the same plane.

[0020] A further preferred embodiment of this utility model is: the bottom of both sides of the box cover is provided with reinforcing ribs, which are connected to the grooves to enhance the strength of the box cover limiting structure.

[0021] A further preferred embodiment of this utility model is that: the two foldable side panels of the box body form a compact folded state with the bottom plate and the rear plate after folding, and the box lid is hidden in the cavity when folded, so that the shopping cart occupies less space when not in use, making it easier to store and transport.

[0022] Compared with existing technologies, the advantages of this invention are: Based on the rotatable lid and body, an independent limiting structure is incorporated to ensure the stability and reliability of the lid during the flipping process. This technology not only allows the lid to flip smoothly 90 degrees and accurately close onto the body, but also effectively prevents the lid from detaching from the body due to external impact or improper operation. Through this independent limiting structure, the safety of the lid during use is significantly improved, reducing damage caused by the lid detaching.

[0023] The limiting structure is designed as a large, blocky unit, significantly enhancing its resistance to wear, aging, and deformation. During long-term use, frequent flipping and contact between the lid and body can easily lead to wear and aging. By employing a large, blocky limiting structure, not only is the physical strength of the limiting structure increased, but its service life is also extended.

[0024] By optimizing the connection between the lid and the body, the lid can be concealed inside the body, resulting in a cleaner and more compact appearance when the shopping cart is not in use. This not only saves space but also enhances the overall aesthetics of the cart. Furthermore, the lid's flipping operation is smoother and more convenient, eliminating concerns about operational difficulties or jamming caused by poor structural design. These optimizations significantly improve the ease of use of the shopping cart. Attached Figure Description

[0035] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0036] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it will not be further defined and explained in subsequent figures.

[0037] like Figures 1 to 3 As shown, the shopping cart 100, whose lid can be hidden inside the box body, mainly includes a box body 10 and a box lid 20. Wheels 11 are installed at the bottom of the box body 10 for easy movement of the shopping cart. The box body 10 consists of a base plate 17, a rear plate 12, a front plate 13, and two foldable side plates 14. A retractable pull rod 15 is installed on the rear plate 12, allowing users to adjust the height of the pull rod as needed, improving ease of use.

[0038] The rear panel 12 further includes a rear base plate 121 and two side bends 122, which extend towards the front panel 13. A barrier plate 30 is connected to the side bends 122 via screw assemblies, thereby forming a cavity h specifically for accommodating the lid 20. This technique not only provides a concealed space for the lid but also optimizes the overall structural layout of the shopping cart.

[0039] like Figures 4 to 9 As shown, a rotating connection structure 40 and a limiting structure 50 are provided between the upper end of the side wall of cavity h and the bottom of lid 20. The rotating connection structure 40 allows lid 20 to move upward along cavity h, and after reaching the upper position of cavity h, it flips at a 90-degree angle and covers box 10. This technical means ensures the flexibility and convenience of lid 20 during use, while ensuring a tight fit between lid 20 and box 10.

[0040] The limiting structure 50 ensures that the lid 20 will not detach from the box body 10 during use. Through the combination of these two technical means, the shopping cart 100 not only realizes the function of hiding the lid 20, but also significantly improves the reliability of the lid 20's flipping and the stability of the overall structure, effectively solving the problems of easy detachment and unreliable flipping of the lid in the existing technology.

[0041] Preferably, the barrier plate 30 includes a plate body 31, side plates 32, and a connecting portion 33. The side plates 32 are vertically distributed on the side of the plate body 31 to form a stable structure. The connecting portion 33 is located on the outside of the side plates 32, and the connecting portion 33 is fixed to the bending portion 122 by a plurality of screws to achieve a stable connection between the barrier plate 30 and the rear plate.

[0042] More specifically, the rotating connection structure 40 is the key technical means to realize the flipping function of the lid 20. Specifically, the upper inner side of the side plate 32 is provided with an elastic protrusion 41, while the bottom of both sides of the lid 20 is provided with a groove 42 that matches it. The elastic protrusion 41 faces the lid 20 inside the cavity h, and its height is higher than the upper surface of the plate 31, thus providing a fulcrum and support for the flipping of the lid 20.

[0043] As the lid 20 moves upward along the cavity h and rotates 90 degrees, the height difference of the elastic protrusions 41 ensures that the groove 42 of the lid 20 can smoothly align with and embed into the elastic protrusions 41. This technique avoids structural interference between the lid 20 and the plate 31 or the rear plate 12 during the rotation process, thus ensuring the smooth rotation action.

[0044] When it is necessary to close the lid 20, the user simply moves the lid 20 upwards along the cavity h. As the lid 20 rises, the grooves 42 on the bottom of its two sides gradually approach the elastic protrusions 41. When the grooves 42 align with and fall into the elastic protrusions 41, the lid 20 can rotate around the elastic protrusions 41. By rotating 90 degrees, the lid 20 can accurately close onto the box 10, thus completely sealing the box's receiving cavity f. This process is not only simple to operate, but also, due to the presence of the elastic protrusions 41, makes the flipping of the lid 20 more stable and reliable, effectively avoiding the problem of the lid falling off due to external impact or improper operation, ensuring the sealing and safety of the shopping cart during use.

[0045] In addition, to further enhance the connection stability between the lid 20 and the body 10, this embodiment also provides a limiting structure 50. The limiting structure 50 consists of two parts: a first limiting structure 51 and a second limiting structure 52. The first limiting structure 51 is located on the upper side of the plate 31, specifically as two protruding plates v1; while the second limiting structure 52 is located at the bottom of the lid 20, and is a groove v2 that cooperates with the protruding plates v1.

[0046] The presence of this limiting structure 50 allows the lid 20 to be precisely positioned and fixed during the flipping and closing process, effectively preventing the lid 20 from shifting or falling off due to external force or improper operation, thereby ensuring the safety and reliability of the shopping cart during use.

[0047] Preferably, the upper end of the side plate 32 is provided with a central column c1 and two side columns c2, and a gap c3 is provided between the central column c1 and the two side columns c2. The elastic protrusion 41 is arranged on the central column c1.

[0048] On the one hand, the elasticity of the intermediate post c1 allows the elastic protrusion 41 to have a certain degree of flexibility when engaging with the groove 42 of the cover 20. This flexibility allows the elastic protrusion 41 to automatically adjust its position when the groove 42 enters, ensuring that the two can fit together smoothly.

[0049] The elastic support of the intermediate column c1 not only ensures that the lid 20 can rotate smoothly around the elastic protrusion 41 during the flipping process, but also can buffer and absorb the impact force through elastic deformation when subjected to external impact, thereby protecting the structure of the lid 20 and the box body 10 from damage.

[0050] Preferably, in this embodiment, the connecting portion 33 is provided with a plurality of first connecting posts 01, and the bending portion 122 is provided with a plurality of identical second connecting posts. The first connecting posts 01 and the second connecting posts are fixed together by screws. The size and shape of these connecting posts are specifically designed to ensure that the two can perfectly match. During the assembly process, the first connecting posts 01 and the second connecting posts are fixed together by using screws, thereby achieving a stable connection between the barrier plate 30 and the rear plate 12.

[0051] like Figure 9 As shown, the bottom of both sides of the box cover 20 is provided with reinforcing ribs r, which are connected to the groove v2 to enhance the strength of the limiting structure 50 of the box cover 20.

[0052] The two foldable side panels 14 of the box body 10 form a compact folded state with the bottom panel 17 and the rear panel 12 after folding. The lid 20 is hidden inside the cavity h when folded, so that the shopping cart occupies less space when not in use, making it easier to store and transport.

[0053] When the lid 20 is closed, its outer wall surface is flush with the top walls of the panels forming the body 10. This gives the shopping cart a flat and uniform appearance when closed, avoiding any disharmony caused by the height difference between the lid 20 and the body 10. This flat appearance not only enhances the overall aesthetics of the shopping cart but also makes it more in line with modern design concepts in supermarkets or shopping malls, thus strengthening the product's market competitiveness.
