Description

Technical Field

[0001] This utility model relates to the field of shopping cart technology, specifically to a multifunctional shopping cart. Background Technology

[0002] A shopping cart is a handcart used by users to transport purchased items. A shopping cart mainly consists of a frame, handles, and wheels. Several wheels are located at the bottom of the frame, and the handles are connected to the frame for the user to push. Items are placed on the frame. Shopping carts can be divided into supermarket shopping carts and household shopping carts. Supermarket shopping carts are mostly multi-tiered and can accommodate children, while household shopping carts have an L-shaped frame and can be fitted with cloth bags to hold goods. Household shopping carts can be used not only as shopping carts but also for transporting goods, offering multiple functions. However, the fixed frame of household shopping carts makes them difficult to store, causing inconvenience in use. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a multifunctional shopping cart to solve the technical problems of shopping carts in the existing technology being inconvenient to store and use.

[0004] To solve the above-mentioned technical problems, this utility model provides a multi-functional shopping cart, including a frame, the frame including a base frame and a side frame, the side frame being hinged to the base frame, a limiting member being slidably connected on the base frame, a limiting groove being provided on the side frame, and an elastic member being provided on the base frame to drive the limiting member into the limiting groove so that the base frame and the side frame cannot rotate.

[0005] With the above structure, the multifunctional shopping cart of this utility model has the following advantages: In use, the base frame and side frame are unfolded. At this time, the elastic element drives the limiting element into the limiting groove, so that the base frame and side frame cannot rotate and the shopping cart cannot be folded. After using the shopping cart, the limiting element is moved to make the limiting element leave the limiting groove and lose its limiting function. At this time, the base frame or side frame can be rotated to make the base frame and side frame close together and the shopping cart can be folded, reducing the storage volume of the shopping cart and making it more convenient to use.

[0006] As an improvement, the underframe includes two hollow tubes, each with a groove along its length. The limiting element is a pull rod slidably connected to the two grooves along the length of the hollow tube. Each hollow tube contains an elastic element that abuts against the pull rod. The side frame includes two connecting rods and two connecting blocks, each connected to one of the connecting rods. The connecting blocks are hinged to the hollow tubes, and the front end of the connecting blocks has a limiting groove along the length of the hollow tube. With this structure, the grooves on the two hollow tubes limit and guide the sliding of the pull rods, allowing the elastic element to accurately push the pull rods into the limiting grooves. The side frame also includes two connecting rods and two connecting blocks, with the limiting grooves of the two connecting blocks limiting the ends of the pull rods, thus achieving stable limiting of the underframe and side frame and improving the stability of the frame in the unfolded state.

[0007] As an improvement, the grooves on each hollow tube run through both ends of the hollow tube, and the two ends of the tie rod are exposed outside the hollow tube through the grooves. The connecting block is a U-shaped block including two connecting pieces on the left and right. The front end of each connecting piece is provided with a limiting groove, and the two connecting pieces are located on the left and right sides of the hollow tube respectively. With this structure, the tie rod can be inserted into the four limiting grooves, further improving the stability of the frame in the unfolded state.

[0008] As an improvement, crossbars are connected between the two hollow tubes and between the two connecting rods; this structure improves the stability of the base frame and side frame structure and makes it easier to set up cloth bags to hold items.

[0009] As an improvement, a handle is rotatably connected to the upper end of the side shelf; with this structure, the rotatable handle allows for a smaller storage volume when the shopping cart is stored.

[0010] As an improvement, a flexible sleeve is fitted onto the handle; this structure enhances the comfort of using the shopping cart.

[0011] As an improvement, several wheels are attached to the bottom of the frame.

[0012] As an improvement, two wheels are connected to the bottom front of the underframe, and two wheels are connected to the bottom side of the underframe. The bottom side of the underframe is equipped with a brake assembly for locking the wheels. Attached Figure Description

Detailed Implementation

[0020] The following is a detailed description of a multifunctional shopping cart according to the present invention, with reference to the accompanying drawings.

[0021] like Figures 1 to 6 As shown, a multi-functional shopping cart includes a frame 100, which includes a base frame 1 and side frames 2. The side frames 2 are hinged to the base frame 1. A limiting member is slidably connected to the base frame 1. A limiting groove 4 is provided on the side frames 2. An elastic member 5 is provided on the base frame 1 to drive the limiting member into the limiting groove 4, preventing the base frame 1 and side frames 2 from rotating. It should be noted that in this utility model, the forward direction of the shopping cart during use is considered the front side. Figure 1 As shown, in the unfolded state, the chassis 100 has a generally horizontal base frame 1 and a generally vertical side frame 2, forming an L-shaped structure. The side frame 2 is located entirely behind the base frame 1, and a space for placing a cloth bag is formed above the base frame 1 and in front of the side frame 2. Furthermore, in some other embodiments, a limiting member can be provided on the side frame 2, while a limiting groove 4 can be provided on the base frame 1.

[0022] When in use, the base frame 1 and side frame 2 are unfolded. At this time, the elastic element 5 drives the limiting element into the limiting groove 4, so that the base frame 1 and side frame 2 cannot rotate and the shopping cart cannot be folded. After using the shopping cart, the limiting element is moved to make it leave the limiting groove 4 and lose its limiting function. At this time, the base frame 1 or side frame 2 can be rotated to make the base frame 1 and side frame 2 close together and the shopping cart can be folded, reducing the storage volume of the shopping cart and making it more convenient to use.

[0023] like Figure 3 As shown, the base frame 1 includes two hollow tubes 11, each hollow tube 11 having a groove 6 arranged along its length. The grooves 6 of the two hollow tubes 11 are positioned correspondingly. The limiting element is a pull rod 3 slidably connected within the two grooves 6 along the length of the hollow tube 11. Each hollow tube 11 has an elastic element 5 that abuts against the pull rod 3. Figure 6 As shown, the elastic element 5 in this embodiment is a spring; the diameter of the middle part of the pull rod 3 is larger than the diameter of both ends of the pull rod 3, so that both ends of the pull rod 3 can slide in the slide groove 6, and the diameter of the middle part of the pull rod 3 is larger than the width of the slide groove 6, thereby limiting the pull rod 3 and preventing the pull rod 3 from detaching from the hollow tube 11.

[0024] like Figure 4 and Figure 5 As shown, the side frame 2 includes two connecting rods 21 and two connecting blocks 22 respectively connected to one of the connecting rods 21. The connecting blocks 22 are hinged to the hollow tube 11, and the front end of the connecting block 22 is provided with a limiting groove 4 arranged along the length direction of the hollow tube 11.

[0025] Specifically, such as Figure 1 and Figure 2 As shown, the grooves 6 on each hollow tube 11 extend through both ends of the hollow tube 11, and the two ends of the pull rod 3 protrude outside the hollow tube 11 through the grooves 6, as shown. Figure 5 As shown, the connecting block 22 is a U-shaped block including two connecting pieces 221 on the left and right. Each of the two connecting pieces 221 has a limiting groove 4 at its front end. The two connecting pieces 221 are located on the left and right sides of the hollow tube 11 and are hinged to the hollow tube 11. In addition, the bottom ends of the two connecting pieces 221 are connected by a base plate 222. When the side frame 2 and the base frame 1 are rotated from the folded state to the unfolded state, the base plate 222 abuts against the bottom end of the hollow tube 11, thereby making the shopping cart at the maximum unfolding angle.

[0026] like Figure 1 As shown, crossbars 7 are connected between the two hollow tubes 11 and between the two connecting rods 21.

[0027] like Figure 1 and Figure 4 As shown, a handle 8 is rotatably connected to the upper end of the side frame 2. Specifically, the handle 8 is connected to two connecting rods 21, and a flexible sleeve 9 is fitted onto the handle 8. Figure 1 As shown, several wheels 10 are connected to the bottom end of the frame 100, such as... Figure 3 and Figure 4 As shown, the bottom front end of the base frame 1 is connected to two wheels 10, and the bottom end of the side frame 2 is connected to two wheels 10. The bottom end of the side frame 2 is provided with a brake assembly for locking the wheels 10. The rotation structure of the handle 8 and the specific structure of the brake assembly are existing technologies, commonly found in shopping carts or campervans in the prior art, and will not be described in detail here.

[0028] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above-described embodiment. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
