Description

Technical Field

[0001] This utility model relates to the field of folding shopping cart technology, and more specifically, to a side panel anti-tipping structure and a folding shopping cart. Background Technology

[0002] Shopping carts are a common tool used by people when shopping. They allow people to put purchased items into the cart and then move it around. Folding shopping carts are a type of shopping cart that can be folded up when not in use, thus reducing the space they take up when not in use.

[0003] The side panels of the folding shopping cart are composed of two hinged panels. When the cart is folded, the two panels rotate and fit together, resulting in a smaller folded size. In existing folding shopping carts, the two side panels are unfolded when in use, and are mainly restrained by the top cover to prevent them from folding or tipping over. However, when loading or unloading items from the cart, the top cover must be opened. At this time, the rotation of the two panels is no longer restricted, making them prone to tipping over and folding, thus affecting the normal use of the cart. Utility Model Content

[0004] To address at least one of the aforementioned problems, this utility model first provides a side panel anti-rollover structure, comprising a first plate, a second plate, and a sliding hook plate. The first plate and the second plate are hinged together, and the sliding hook plate is slidably disposed on the first plate. When the first plate and the second plate are in a fully open state, one end of the sliding hook plate is hooked to the second plate to limit the rotation of the first plate and the second plate. An elastic element is provided on one side of the sliding hook plate, and one end of the elastic element abuts against the sliding hook plate to drive the sliding hook plate to maintain a continuous hooked connection with the second plate.

[0005] Optionally, the second plate is provided with a rotating baffle. When the first plate and the second plate are in a fully open state, the rotating baffle is located on one side of the first plate and abuts against the first plate.

[0006] Optionally, the sliding hook plate is slidably disposed on the side of the first plate that abuts against the rotating baffle. The rotating baffle has a mating hole on the side that fits against the first plate. The mating hole passes through the rotating baffle, and one end of the sliding hook plate passes through the mating hole and is hooked to the rotating baffle.

[0007] Optionally, the sliding hook plate includes a sliding plate and a snap-fit ​​hook. The snap-fit ​​hook is fixedly disposed on the side of the sliding plate opposite to the first plate body. The sliding plate slides on the first plate body. The snap-fit ​​hook passes through the mating hole and is hooked and connected to the side of the rotating baffle opposite to the first plate body.

[0008] Optionally, the elastic element is a spring, and an abutment block is provided on one side of the sliding plate in the sliding direction. The abutment block is fixedly connected to the first plate body, and the two ends of the elastic element abut against the sliding plate and the abutment block, respectively.

[0009] Optionally, the fastening hook has a slot on one side along the sliding direction of the sliding plate, and the rotating baffle is inserted into the slot.

[0010] Optionally, the top of the side of the latching hook where the slot is opened is provided with an inclined surface.

[0011] Optionally, a sliding groove is provided on the side of the first plate that abuts against the rotating baffle, the sliding plate slides in the sliding groove, a limiting baffle is fixedly provided at the opening of the sliding groove, and the two ends of the sliding plate in the sliding direction are respectively located on both sides of the limiting baffle.

[0012] Optionally, the sliding groove has a limiting groove on its wall perpendicular to the sliding direction of the sliding plate, and the sliding plate has a snap-fit ​​hook fixedly provided on its side wall. The snap-fit ​​hook moves in a directional manner within the limiting groove to limit the moving distance of the sliding plate.

[0013] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0014] 1. When the first plate and the second plate are fully open, one end of the sliding hook plate can be hooked to the second plate to limit the relative rotation of the first plate and the second plate, so that the first plate and the second plate are not prone to relative rotation and overturning.

[0015] 2. The rotating baffle is inserted into the slot. When the first plate and the second plate are subjected to folding force, the rotating baffle and the fastening hook will form a hook-like structure and fasten together, making it difficult for the first plate and the second plate to bend and flip over after being subjected to force, thus improving the stability of the first plate and the second plate in the fully unfolded state.

[0016] 3. The elastic element can drive the rotating baffle to remain inserted in the slot, making it difficult for the sliding hook plate to easily release the locking state of the rotating baffle, thus improving the stability of the sliding hook plate in the locked state.

[0017] 4. When the second plate rotates relative to the first plate from a folded state to an open state, the inner edge of the mating hole on the rotating baffle will press against the inclined surface on the snap hook, causing the entire sliding snap hook plate to move automatically to make room so that the snap hook can be inserted into the mating hole. This allows the sliding snap hook plate to limit the rotation of the first and second plates. The above process does not require moving the sliding snap hook plate separately to make room; it is only necessary to open the first and second plates. The operation is simple and convenient.

[0018] In addition, this utility model provides a folding shopping cart, including the side panel anti-tipping structure described above.

[0019] Compared with the prior art, the folding shopping cart described in this utility model has the same advantages as the aforementioned side panel anti-flip structure, which will not be repeated here. Attached Figure Description

Detailed Implementation

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the following description is provided in conjunction with the appendix. Figure 1-4 This application will be described in further detail.

[0026] In a first aspect, this utility model embodiment provides a side panel anti-rollover structure, referring to... Figure 1 and Figure 2The side panel anti-rollover structure includes a first plate 1, a second plate 2, and a sliding hook plate 3. The ends of the first plate 1 and the second plate 2 that are close to each other are hinged together by a hinge shaft. The sliding hook plate 3 is slidably disposed on the first plate 1. When the first plate 1 and the second plate 2 are in the fully open state, one end of the sliding hook plate 3 is hooked to the second plate 2 to limit the rotation of the first plate 1 and the second plate 2.

[0027] Let the hinge end of the first plate 1 and the second plate 2 be the hinge end of the first plate 1; let the hinge end of the second plate 2 and the first plate 1 be the hinge end of the second plate 2. When the first plate 1 and the second plate 2 are folded, they can fit together. The hinge end of the second plate 2 has an integrally formed rotating baffle 21. When the first plate 1 and the second plate 2 are fully open, this baffle is located on one side of the first plate 1 and abuts against the inner wall of the first plate 1. After the first plate 1 rotates 180 degrees relative to the second plate 2, it is limited by the rotating baffle 21 and cannot continue to rotate in the opening direction. The sliding hook plate 3 locks the folding and flipping of the first plate 1 and the second plate 2.

[0028] Reference Figure 1 and Figure 2 The sliding hook plate 3 is located on the side of the first plate 1 that abuts against the rotating baffle 21 when the first plate 1 is open. The sliding hook plate 3 can move closer to or away from the hinge end of the second plate 2 on the first plate 1. The sliding hook plate 3 will cooperate with the rotating baffle 21 to lock so that the first plate 1 and the second plate 2 are not prone to relative rotation and overturning.

[0029] Reference Figure 2 and Figure 3 Specifically, the sliding hook plate 3 includes a sliding plate 31 and a snap-fit ​​hook 32. The snap-fit ​​hook 32 is integrally formed on the side of the sliding plate 31 facing away from the first plate 1. This integral forming improves the strength of the snap-fit ​​hook 32 after it is connected to the sliding plate 31. In another embodiment, the sliding plate 31 and the snap-fit ​​hook 32 can also be fixedly connected by fasteners. A mating hole 22 is provided on the side of the rotating baffle 21 that is in contact with the first plate 1. The mating hole 22 passes through the rotating baffle 21. After the snap-fit ​​hook 32 passes through the mating hole 22, it will be mated and hooked to the side of the rotating baffle 21 facing away from the first plate 1, thereby locking the rotation of the rotating baffle 21.

[0030] A sliding groove 11 is provided on the side of the first plate 1 that abuts against the rotating baffle 21. The sliding plate 31 slides in the sliding groove 11. Placing the sliding plate 31 in the sliding groove 11 can reduce the space occupied by the sliding plate 31 on the first plate 1, making the sliding plate 31 less likely to protrude too much, and preventing items from touching the sliding plate 31 when taking them out or putting them in.

[0031] Reference Figure 2 and Figure 3A limiting baffle 12 is integrally formed at the opening of the sliding groove 11. The length of the limiting baffle 12 along the sliding direction of the sliding plate 31 is less than the length of the sliding groove 11 along the sliding direction of the sliding plate 31. The two ends of the sliding plate 31 in the sliding direction are respectively located on both sides of the limiting baffle 12. In this way, the sliding plate 31 is less likely to fall off the first plate 1 from the opening of the sliding groove 11. In addition, it is also more convenient to assemble the sliding plate 31 into the sliding groove 11.

[0032] Reference Figure 3 and Figure 4 The sliding groove 11 has two groove walls perpendicular to the sliding direction of the sliding plate 31, each with a limiting groove 13. The limiting groove 13, near the opening of the sliding groove 11, penetrates the first plate 1 and communicates with the opening of the sliding groove 11. Each of the two outer walls of the sliding plate 31 has a locking hook 33, located within the two limiting grooves 13. During the movement of the sliding plate 31, the locking hook 33 moves within the corresponding limiting groove 13. When the locking hook 33 abuts against the groove wall of the limiting groove 13 along the moving direction of the sliding plate 31, it acts as a limit, preventing the sliding plate 31 from moving further and thus limiting the movement distance of the sliding plate 31, ensuring the accuracy of the engagement between the locking hook 32 and the rotating baffle 21. In addition, when installing the sliding plate 31, the snap-fit ​​hook 33 is more likely to deform and make room to ensure the smoothness of the installation of the sliding plate 31.

[0033] Reference Figure 2 and Figure 3 The latching hook 32 has a slot 34 on the side away from the hinge end of the first plate 1 along the sliding direction. The slot 34 and the side of the latching hook 32 away from the sliding plate 31 are arranged at intervals. When the latching hook 32 is inserted into the mating hole 22 and the end of the latching hook 32 away from the sliding plate 31 passes through the mating hole 22, the inner wall of the rotating baffle 21 at the corresponding position will be inserted into the slot 34. At this time, the latching hook 32 is similar to a hook to hook the rotating baffle 21, so that the rotating baffle 21 is not easy to rotate relative to the first plate 1, and thus the second plate 2 and the first plate 1 are not easy to rotate relative to each other.

[0034] Combination Figure 2 Reference Figure 3 and Figure 4 An elastic element 4 is provided at one end of the sliding plate 31 near the hinge end of the first plate 1. The elastic element 4 drives the inner wall of the rotating baffle 21 to always tend to be inserted into the slot 34, so that the latching hook 32 can continuously maintain a hook-and-connection state with the rotating baffle 21, thereby improving the stability of the rotational locking of the first plate 1 and the second plate 2.

[0035] In this embodiment, the elastic element 4 is preferably a spring. The bottom of the sliding groove 11 is integrally formed with an abutment block 14, which is located on the side of the sliding plate 31 near the hinge end of the first plate 1. The abutment block 14 and the sliding plate 31 are arranged at intervals. The two ends of the elastic element 4 abut against the sliding plate 31 and the abutment block 14 respectively, thereby driving the inner wall of the rotating baffle 21 to always tend to be inserted into the slot 34. In another embodiment, the elastic element 4 can be a V-shaped spring sheet, with its two outer walls abutting against the sliding plate 31 and the abutment block 14 respectively.

[0036] Combination Figure 2 Reference Figure 3 and Figure 4 The top of the snap hook 32, on the side with the slot 34, has an inclined surface 35. The distance from the inclined surface 35 near the hinge end of the first plate 1 to the sliding plate 31 is greater than the distance from the inclined surface 35 away from the hinge end of the first plate 1 to the sliding plate 31. When the second plate 2 rotates relative to the first plate 1 from a folded state to an open state, the inner edge of the mating hole 22 on the rotating baffle 21 will press against the inclined surface 35 on the snap hook 32, causing the entire sliding hook plate 3 to move automatically to make room so that the snap hook 32 can be inserted into the mating hole 22.

[0037] The implementation principle of the side panel anti-flip structure in this application embodiment is as follows: When the second plate 2 rotates relative to the first plate 1 from a folded state to an open state, the inner edge of the mating hole 22 on the rotating baffle 21 will press the inclined surface 35 on the fastening hook 32, causing the entire sliding hook plate 3 to automatically move closer to the hinge end of the first plate 1 to make room and press the elastic element 4 so that the fastening hook 32 can be inserted into the mating hole 22.

[0038] After the rotating baffle 21 comes into contact with the first plate 1, the sliding plate 31 will automatically move and reset under the action of the elastic element 4, and the inner wall of the rotating baffle 21 will be inserted into the slot 34. At this time, the latch 32 is like a hook that holds the rotating baffle 21, making it difficult for the rotating baffle 21 to rotate relative to the first plate 1, effectively preventing the first plate 1 and the second plate 2 from flipping over after they are fully unfolded.

[0039] Secondly, another embodiment of the present invention provides a folding shopping cart, which is equipped with the side panel anti-tipping structure described in the first aspect above. The sliding hook plate 3 is located inside the folding shopping cart, thereby ensuring the flatness and aesthetics of the exterior of the folding shopping cart.
