Description

Technical Field

[0001] This utility model relates to the field of folding shopping cart technology, and in particular to an adjustable folding shopping cart. Background Technology

[0002] With the fast pace of urban life, portable shopping carts have become a common tool for residents' daily shopping. These carts typically consist of a metal frame and fabric storage bags, featuring lightweight and foldable designs to meet the purchasing needs of supermarkets and farmers' markets. Their compact size when folded makes them easy to store in homes or car trunks, making them popular with elderly users and frequent shoppers. In existing technologies, these products achieve their folding function through hinges or plug-in structures.

[0003] However, the storage design of traditional grocery shopping carts still has significant flaws. Although most products use open mesh bags or canvas bags as containers, they lack a reasonable partitioning structure, and the fruits, vegetables, and fresh produce purchased by users are often piled up haphazardly in the same space. Soft ingredients are easily deformed by the pressure of hard objects, leading to damage; at the same time, leakage of liquid ingredients or mixing of raw and cooked foods may cause hygiene problems. In addition, the storage space of existing folding carts is fixed and cannot be dynamically adjusted according to the type and quantity of items. When fully loaded, items are prone to scattering due to shaking, and when empty, the loose structure reduces the stability of the cart. These problems seriously affect the user experience and urgently need to be improved through structural innovation. Utility Model Content

[0022] 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.

[0023] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0024] This embodiment mainly describes the structure of the folding shopping cart, as follows:

[0025] An adjustable folding shopping cart, such as Figures 1-4As shown, the assembly includes a movable frame 1, a placement bag 2, a first fixing plate 3, a compression plate 4, a first return spring 5, a movable plate 7, a baffle 8, a slider 81, a second fixing plate 9, and a layering assembly. The placement bag 2 is snapped onto the movable frame 1 via a latch connected to its rear side. The first fixing plate 3 is slidably connected to the top frame of the placement bag 2, and the compression plate 4 is slidably connected to the top of the first fixing plate 3. Several first return springs 5 ​​are provided on the top of the first fixing plate 3, located between the first fixing plate 3 and the compression plate 4. One end of each first return spring 5 is connected to the first fixing plate 3, and the other end is connected to the compression plate 4. Several limiting holes 6 are opened in the top frame of the placement bag 2. Circular protrusions are provided at both ends of the compression plate 4, which are matched with the limiting holes 6 of the placement bag 2 for limiting. The second fixing plate 9 is connected to the front and rear ends of the bottom frame of the placement bag 2. The upper end of the movable plate 7 is connected to the first fixed plate 3, and the lower end is slidably connected to the second fixed plate 9. The top of the baffle 8 is connected to the first fixed plate 3. The left and right sides of the baffle 8 are connected to sliders 81, which are slidably connected to the movable plate 7. The placement bag 2 is provided with a layered component for setting the placement depth. When the user pushes the first fixed plate 3 horizontally, it causes the extrusion plate 4 fixed to it to slide. When the extrusion plate 4 moves, its circular protrusions extrude the first return spring 5 and disengage from the current limiting hole 6. When it slides to the target position, such as dividing into left and right sections, the first return spring 5 rebounds and pushes the protrusions into the corresponding limiting holes 6. The baffle 8 is horizontally expanded or contracted along the movable plate 7 by the sliders 81. The bottom counterweight 19 makes the baffle 8 hang down naturally to form a vertical division, avoiding compression deformation caused by mixing soft and hard food.

[0026] like Figure 2 , Figure 5 and Figure 6 As shown, the layered assembly includes a support plate 10, a mounting plate 11, guide rods 12, screws 13, and a buffer assembly 14. The top and bottom frames of the placement bag 2 are connected to several support plates 10. Guide rods 12 are connected between the support plates 10 at corresponding upper and lower positions. The screws 13 are rotatably connected to the support plates 10. The mounting plate 11 is slidably connected to all the guide rods 12. The mounting plate 11 is threadedly connected to the screws 13. A buffer assembly 14 for stabilizing the mounting plate 11 is provided on the top of the screws 13.

[0027] like Figure 5 and Figure 6As shown, the buffer assembly 14 includes a positioning block 141, a limiting member 143, and a second return spring 144. Several grooves 142 are circumferentially formed around the upper part of the screw 13. The top of the support plate 10, which is rotatably connected to the screw 13, is connected to the positioning block 141. The positioning block 141 is slidably connected to the limiting member 143. The end of the limiting member 143 is in a limiting fit with the groove 142. The sidewall of the groove 142 has a sloping structure. When the screw 13 is rotated in the opposite direction, the limiting member 143 automatically retracts under the thrust of the sloping surface. The second return spring 144 is sleeved on the limiting member 143. One end of the second return spring 144 is connected to the positioning block 141, and the other end is connected to the limiting member 143. The user holds the rubber knob 15. Rotating screw 13 drives mounting plate 11 to move up and down along guide rod 12, causing support plate 10 to rise and fall synchronously. When adjusting upwards, limit piece 143 is pulled outwards to release the engagement with groove 142 of screw 13. At this time, the second reset spring 144 is compressed. After rotating to the correct position, limit piece 143 is released, and the spring rebounds to insert into groove 142 to lock the height. When resetting downwards, screw 13 is rotated in the opposite direction, and limit piece 143 slides along the inclined surface of groove 142 and automatically disengages. Support plate 10 descends smoothly to the initial position. After the food is raised with support plate 10, the user can pick it up without bending over. After resetting, support plate 10 descends to the bottom, maintaining low center of gravity stability when folded.

[0028] like Figure 5 As shown, it also includes a rubber knob 15. The top of the screw 13 is fitted with a rubber knob 15 to increase friction and make it easier for the user to apply force to rotate the screw 13.

[0029] like Figure 2 As shown, it also includes label cards 16. Several label cards 16 are evenly spaced on the inside of the storage bag 2. The labels "low position - middle position - high position" are displayed according to the height of the support plate 10, which intuitively indicates the food storage layer.

[0030] like Figure 2 As shown, it also includes an auxiliary plate 17. The first fixed plate 3 is connected to the auxiliary plate 17, which is located on the side of the first fixed plate 3 to provide an additional force application point and reduce the operating intensity of the user pushing and pulling the rod.

[0031] like Figure 1 As shown, it also includes reflective sticker 18. The outer side of the bag 2 is equipped with reflective sticker 18, which reflects red light when illuminated at night to warn surrounding vehicles and ensure pedestrian safety.

[0032] like Figure 4 As shown, it also includes a counterweight 19, and the bottom of the baffle 8 is connected to the counterweight 19.

[0033] The user pushes the first fixed plate 3 laterally, causing the squeezing plate 4 to slide. At this time, the circular protrusions at both ends of the squeezing plate 4 compress the first return spring 5 and disengage from the limiting hole 6 at the top of the placement bag 2. When the slide reaches the target position, the first return spring 5 rebounds, pushing the protrusions into the new limiting hole 6, thus locking the position. At the same time, the baffle 8 unfolds laterally along the moving plate 7 via the sliders 81 on both sides, and the counterweight 19 at its bottom hangs down naturally under the action of gravity, forming a stable vertical partition area inside the placement bag 2, separating fragile soft food from hard items to prevent them from being squeezed together. When it is necessary to adjust the retrieval height, the user holds the rubber knob 15 at the top of the screw 13 and rotates it clockwise, driving the mounting plate 11 to rise along the guide rod 12, which in turn drives the support plate 10 to lift the food to the "high position" indicated by the label 16. During this process, pulling out the limiting member 143 compresses the second reset spring 144, allowing the screw 13 to rotate freely. After adjustment, releasing the limiting member 143 causes the spring to rebound, locking its end into the groove 142 of the screw 13, thus achieving height locking. This allows the elderly to easily retrieve items without bending over. After use, rotating the screw 13 counterclockwise causes the limiting member 143 to slide out along the inclined surface of the groove 142, allowing the support plate 10 to descend smoothly to its initial bottom position. The counterweight 19 then moves down to maintain the tension of the barrier cloth 8, preventing structural loosening after reset. Finally, the user releases the latch on the back of the mobile frame 1, folding and retracting the first fixing plate 3 and the layered assembly. The entire device shrinks into a compact form, making it easy to store in small spaces. When used at night, the reflective sticker 18 on the outside of the storage bag 2 enhances visibility through light reflection, while the auxiliary plate 17 provides an additional force application point for the push-pull rod, reducing operational intensity.
