Technical Field

[0001] The utility model relates to the technical field of shopping carts, in particular to a shopping cart with an external extension function. Background Art

[0002] Shopping carts are mainly used to temporarily store purchased items or items to be purchased in supermarkets. They are widely used in supermarkets. However, there is still a distance between the supermarket and the consumer's home. In order to meet the storage needs of items within this distance, household shopping carts are widely used. Especially when carrying some heavier items, shopping carts bring great convenience to people.

[0003] Chinese utility model patent CN219904430U discloses a shopping cart with a brake member that is rotatably mounted on a mounting base. The brake member is not prone to accidental movement, thereby preventing accidents during use and improving the safety of the shopping cart.

[0004] However, the item storage space of this patent is limited. When too many items are loaded at one time, multiple items can only be stacked and placed on top of the shopping cart. When the shopping cart is pushed, due to the lack of a mechanism to expand the storage space, items above the shopping cart are prone to falling. Based on this, we propose a shopping cart with an external extension function. Utility Model Content

However, people familiar with the art should understand that the detailed description given here in conjunction with the drawings is for better explanation, and the structure of the present invention must go beyond these limited embodiments. For some equivalent replacement solutions or common means, they will not be described in detail herein, but they still fall within the scope of protection of this application.

[0022] Figure 1-Figure 5 This is the best embodiment of the present invention, Figure 1-Figure 5 The utility model is further described.

[0023] Refer to the attached Figure 1-Figure 5 A shopping cart with an external extension function includes a shopping cart body 1, a storage hole 2 is opened on the top side of the shopping cart body 1, and also includes an extension mechanism, a positioning mechanism and a blocking mechanism. The extension mechanism is arranged in the storage hole 2, and the extension mechanism is used to expand the storage space of the shopping cart body 1. The positioning mechanism is arranged on one side of the shopping cart body 1, and the positioning mechanism is used to position and fix the extension mechanism after movement. One end of the blocking mechanism is arranged on the top of the extension mechanism, and the blocking mechanism is used to suppress items higher than the top surface of the shopping cart body 1, and the other end of the blocking mechanism is snap-connected with the extension mechanism.

[0024] In this embodiment, the positioning mechanism is used to restrict and fix the position of the extension mechanism when the extension mechanism moves above the shopping cart body 1, and at the same time, the restriction of the blocking mechanism is released. The storage space of the shopping cart body 1 can be expanded through the action of the extension mechanism, and the items slightly higher than the extension mechanism can be suppressed through the blocking mechanism, so that the items are placed more stably.

[0025] Specifically, the extension mechanism includes a mounting frame 4, the outer wall of the mounting frame 4 is slidably connected to the storage hole 2, and a barrier net 19 is fixedly embedded on all sides of the mounting frame 4. A moving hole 3 connected to the storage hole 2 is opened on one side of the shopping cart body 1, and two snap-in holes 5 are opened on the top of the rear side of the mounting frame 4. The two snap-in holes 5 are symmetrically arranged. A moving rod 6 passing through the moving hole 3 is fixedly connected to the bottom of the front side of the mounting frame 4, and one end of the moving rod 6 is fixedly connected to a connecting plate 7. Two guide holes 8 are opened on one side of the connecting plate 7, and the two guide holes 8 are symmetrically arranged. A fixing block 9 is fixedly connected to one side of the connecting plate 7, and a toughness plate 10 is fixedly connected to one side of the fixing block 9.

[0026] In this embodiment, the tough plate 10 is semicircular in shape.

[0027] Specifically, it also includes two guide rods 17 fixedly connected to the top of the moving hole 3 on the front side of the shopping cart body 1. The two guide rods 17 are symmetrically arranged, and positioning holes 18 are opened on the front side of the shopping cart body 1 near the bottom of the two guide rods 17.

[0028] In this embodiment, the bottom of one end of the guide rod 17 is configured as an arc-shaped surface that is concave upwards toward the shopping cart body 1 .

[0029] Specifically, the positioning mechanism includes two positioning rods 12, the bottom end of the connecting plate 7 is fixedly connected to the two extension plates 11, the outer walls of the two positioning rods 12 slide through one side of the two extension plates 11 respectively, one end of the two positioning rods 12 is fixedly connected to the same pull plate 13, and a tension spring 14 is sleeved on the outside of the two positioning rods 12, one end of the tension spring 14 is fixedly connected to one side of the extension plate 11, and the other end is fixedly connected to one side of the pull plate 13.

[0030] In this embodiment, the outer diameter of the positioning rod 12 is adapted to the inner diameter of the positioning hole 18 .

[0031] Specifically, the blocking mechanism includes an elastic cloth 15 , one end of the elastic cloth 15 is arranged on the top of the extension mechanism, and the other end of the elastic cloth 15 is fixedly connected to the embedded rod 16 .

[0032] In this embodiment, the outer wall of the embedded rod 16 is adapted to the interior of the clamping hole 5 .

[0033] Specifically, one end of the elastic cloth 15 is fixedly connected to the inner top of the mounting frame 4 .

[0034] In this embodiment, due to the elasticity of the elastic cloth 15, objects slightly above the mounting frame 4 can be pressed down, making the objects more stable when squeezed.

[0035] When the pull plate 13 approaches the guide rod 17 and the guide hole 8 is sleeved on the guide rod 17, the inclined surface of one end of the guide rod 17 contacts the outer wall of the embedding rod 16 and pushes the embedding rod 16 out of the flexible plate 10, thereby releasing the restriction on the elastic cloth 15. At the same time, the pull plate 13 drives the positioning rod 12 to align with the inside of the positioning hole 18. Due to the force of the tension spring 14, the positioning rod 12 is embedded in the positioning hole 18, restricting and fixing the position of the mounting frame 4, cooperating with the mounting frame 4 and the barrier net 19, expanding the storage space of the shopping cart body 1.

[0036] Secondly, pull the embedded rod 16 so that the embedded rod 16 drives the elastic cloth 15 to flip over, and then the embedded rod 16 is clamped inside the clamping hole 5, thereby limiting the position of the elastic cloth 15 and blocking the items in the mounting frame 4 at the same time, thereby ensuring the stability of the items in the mounting frame 4 and the shopping cart body 1.

[0037] The above description is merely a preferred embodiment of the present invention and does not constitute any limitation thereto. Any person skilled in the art may utilize the above disclosure to modify or remodel the present invention into equivalent embodiments. However, any simple modification, equivalent variation, or modification of the above embodiment that does not depart from the technical content of the present invention and is based on the technical essence of the present invention shall still fall within the scope of protection of the present invention.
