Description

Technical Field

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

[0002] Supermarket shopping carts, a type of trolley, are tools used by customers in self-service retail stores such as supermarkets and hypermarkets to temporarily store and transport selected goods. They are an indispensable part of modern retail, greatly enhancing the shopping experience and efficiency. Traditional supermarket shopping carts typically have four wheels and a square basket. However, the square basket is relatively large, and in high-traffic supermarkets, its wide front end requires more space to maneuver, making it difficult for customers to push the cart through crowds. Therefore, a design with three wheels and a triangular basket is possible, reducing the required width at the front and making it easier for customers to push the cart through the flow of people.

[0003] Different customers have different body types, so there is a need for shopping carts that can be adapted to the corresponding sizes. Conventional shopping carts can usually be adjusted to accommodate people of different heights by adjusting the height of the handle, but in the width direction, existing shopping carts lack adjustment methods. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a supermarket shopping cart with fixed rings on both sides of the goods basket, which are fitted onto a support beam to accommodate changes in the angle of the support beam during the opening and adjustment of the hinge.

[0005] This utility model is achieved through the following technical solution: a supermarket shopping cart, including two support beams, one end of the two support beams is hinged to each other through a hinge part, and the end of the support beam away from the hinge part and the bottom of the hinge part are rotatably connected to wheels; It also includes a cargo basket, with a first fixing ring on each side of the cargo basket. The inner diameter of the first fixing ring is larger than the diameter of the support beam, and the first fixing ring is fitted onto the support beam. Vertical beams are fixedly connected to each support beam. A second fixing ring is provided on each side of the cargo basket. The inner diameter of the second fixing ring is larger than the diameter of the vertical beam, and the second fixing ring is fitted onto the vertical beam. Two support beams are rotatably connected to a constraint sub-rod and a constraint mother rod, respectively. The top of the constraint mother rod abuts against the bottom of the constraint sub-rod. Both the constraint sub-rod and the constraint mother rod have several threaded holes at the ends away from the support beams. The constraint mother rod and the constraint sub-rod are detachably connected by fitting fixing bolts into the threaded holes.

[0006] Furthermore, both the support beams and the vertical beams are hollow structures.

[0007] Furthermore, the top of the vertical beam is open, and a vertical rod is slidably connected inside the vertical beam. Both the vertical rod and the vertical beam are provided with positioning holes, and the vertical rod and the vertical beam are detachably connected by fitting a pin into the positioning hole.

[0008] Furthermore, each vertical pole is fixedly connected to a handle at the top, and the handle has anti-slip texture.

[0009] Furthermore, the wheels on the side of the support beam away from the hinge are all equipped with brakes, and the bottom of the handle is equipped with a brake trigger. The brake trigger activates the brake via a brake cable.

[0010] Furthermore, a cover plate is rotatably connected to the top of the cargo basket.

[0011] Furthermore, a screw cap is provided on the top of the fixing bolt.

[0012] The technical solution of this utility model has at least the following beneficial effects: The support beams are hinged to form the frame of the three-wheeled shopping cart, which moves via wheels at the bottom of the hinges. A basket provides cargo capacity and is connected to the support beams via a first fixing ring. Because the inner diameter of the first fixing ring is larger than the diameter of the support beam, the basket sinks under gravity, causing the inner top wall of the first fixing ring to contact the support beam. The support beam then provides support to the first fixing ring through its inner top wall. A second fixing ring fits onto a vertical beam. Because the inner diameter of the second fixing ring is larger than the diameter of the vertical beam, the second fixing ring restricts the basket's lateral movement.

[0013] Customers can widen the shopping cart by opening the angle between the two support beams through the hinge, making it easier for wider customers to use. Since the inner diameters of the first and second fixing rings are larger than the diameters of the support beams and vertical beams, respectively, the support beams and vertical beams can rotate to a certain extent within the first and second fixing rings. After the support beams rotate, the contact point between the first fixing ring and the support beam changes, while the second fixing ring continues to provide support to the first fixing ring. Similarly, the second fixing ring restricts the lateral movement of the basket, ensuring that the basket remains fixed to the opened support beams.

[0014] To ensure that the included angle between the two support beams can be fixed after the hinge is made, a constraint sub-rod and a constraint mother-rod are set up. When the included angle between the two support beams is changed, the constraint sub-rod and the constraint mother-rod are rotated so that the threaded holes of the constraint sub-rod and the constraint mother-rod overlap. The constraint sub-rod and the constraint mother-rod are then locked together using fixing bolts, thereby fixing the constraint sub-rod and the constraint mother-rod to each other, maintaining the included angle between the two support beams, and thus completing the fixation of the shopping cart width.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0019] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0020] The following detailed description illustrates the specific implementation methods: Example 1 As attached Figures 1-4As shown, a supermarket shopping cart includes two support beams 1. One end of the two support beams 1 is hinged to each other through a hinge part 2. The hinge part 2 is a hinge. The end of the support beam 1 away from the hinge part 2 and the bottom of the hinge part 2 are rotatably connected to wheels 3.

[0021] It also includes a cargo basket 4, with a cover plate 18 rotatably connected to the top of the cargo basket 4. A first fixing ring 5 is provided on the bottom of both sides of the cargo basket 4. The inner diameter of the first fixing ring 5 is larger than the diameter of the support beam 1, and the first fixing ring 5 is fitted onto the support beam 1. Vertical beams 6 are fixedly connected to the support beam 1. A second fixing ring 7 is provided on the top of both sides of the cargo basket 4. The inner diameter of the second fixing ring 7 is larger than the diameter of the vertical beam 6, and the second fixing ring 7 is fitted onto the vertical beam 6.

[0022] Both the support beam 1 and the vertical beam 6 are hollow structures to reduce the overall weight of the shopping cart and the resistance when pushing it. The top of the vertical beam 6 is open, and a vertical rod 12 is slidably connected inside the vertical beam 6. Both the vertical rod 12 and the vertical beam 6 are provided with positioning holes 13. The vertical rod 12 and the vertical beam 6 are detachably connected by a pin 14 that engages with the positioning holes 13. A handle 15 is bolted to the top of each vertical rod 12, and the handle 15 has anti-slip texture. The wheel 3 on the side of the support beam 1 away from the hinge part 2 is equipped with a brake, and a brake trigger 16 is provided at the bottom of each handle 15. The brake trigger 16 triggers the brake through a brake cable 17.

[0023] Two support beams 1 are rotatably connected to a constraint sub-rod 8 and a constraint mother rod 9, respectively. The top of the constraint mother rod 9 abuts against the bottom of the constraint sub-rod 8. Both the constraint sub-rod 8 and the constraint mother rod 9 have several threaded holes 10 at their ends away from the support beams 1. The constraint mother rod 9 and the constraint sub-rod 8 are detachably connected by fitting fixing bolts 11 into the threaded holes 10. The fixing bolts 11 have nuts 19 on their tops.

[0024] The support beam 1 is hinged to form the frame of the three-wheeled shopping cart. The cart moves via the support beam 1 and the wheels 3 at the bottom of the hinge 2. Customers can push the cart by holding the handle 15. The anti-slip texture enhances the friction between the handle 15 and the customer's hand, reducing the probability of slipping. Because the front of the cart is smaller, it has greater maneuverability when moving in crowds. The vertical beam 6 is slidably connected to the vertical rod 12. Customers can pull out the pin 14, slide the vertical rod 12 to adjust the positional relationship between the vertical rod 12 and the vertical beam 6, and change the height of the handle 15. After adjusting the height of the handle 15 to a suitable position, the pin 14 is inserted into the positioning hole 13 to lock the positional relationship between the vertical rod 12 and the vertical beam 6, allowing customers to adjust the handle 15 to a suitable pushing height according to their own height.

[0025] The bottom of the handle 15 is equipped with a brake trigger 16, which allows customers to activate the brake and quickly stop the rotation of the wheel 3, making it easy for customers to quickly control the shopping cart to stop moving.

[0026] The shopping basket 4 provides cargo carrying capacity. A cover 18 is rotatably connected to the top of the shopping basket 4, allowing customers to close it and prevent goods from sliding out of the opening at the top. The shopping basket 4 is connected to the support beam 1 via a first fixing ring 5. Because the inner diameter of the first fixing ring 5 is larger than the diameter of the support beam 1, the shopping basket 4 will sink under gravity, causing the inner top wall of the first fixing ring 5 to contact the support beam 1. The support beam 1 can then provide support to the first fixing ring 5 through its inner top wall. A second fixing ring 7 is fitted onto the vertical beam 6. Because the inner diameter of the second fixing ring 7 is larger than the diameter of the vertical beam 6, the second fixing ring 7 restricts the lateral swing of the shopping basket 4, thus constraining the entire shopping basket 4 to the support beam 1.

[0027] Customers can widen the shopping cart by opening the angle between the two support beams 1 through the hinge 2, making it more convenient for wider customers. Since the inner diameters of the first fixing ring 5 and the second fixing ring 7 are larger than the diameters of the support beam 1 and the vertical beam 6, respectively, the support beam 1 and the vertical beam 6 can rotate to a certain extent within the first fixing ring 5 and the second fixing ring 7. After the support beam 1 rotates, the contact point between the first fixing ring 5 and the support beam 1 changes, while the second fixing ring 7 continues to provide support for the first fixing ring 5. Similarly, the second fixing ring 7 restricts the lateral swing of the basket 4, ensuring that the basket 4 remains fixed to the opened support beam 1.

[0028] To ensure the included angle between the two support beams 1 is fixed after hinge, a constraint sub-rod 8 and a constraint mother-rod 9 are provided. When the included angle between the two support beams 1 is changed, the constraint sub-rod 8 and constraint mother-rod 9 are rotated so that their threaded holes 10 overlap. The constraint sub-rod 8 and constraint mother-rod 9 are then locked together using fixing bolts 11, thus fixing them together and maintaining the included angle between the two support beams 1, thereby fixing the width of the shopping cart. When removing the fixing bolts 11, the caps 19 increase the rotational torque, making disassembly easier for customers.

[0029] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
