Technical Field
[0001] This utility model belongs to the field of handcart technology, specifically referring to a foldable portable handcart. Background Technology
[0002] During the transportation of production materials and finished products, different transportation tools are required depending on the circumstances. While existing handcarts have a strong loading capacity, they occupy a large amount of space and are inconvenient to store. Even handcarts that can be folded for easy storage exist, but their design is not perfect, resulting in excessive height, large space occupation when folded, and inconvenience in both folding and unfolding. Utility Model Content
[0003] This utility model aims to at least solve the problems of traditional handcarts having a high overall height of handle and body after folding, occupying a large space, and the problem that the complex folding mechanism makes folding and opening difficult.
[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: This utility model proposes a foldable portable handcart, including a flexible folding basket for storing items. Both sides of the flexible folding basket are provided with supporting frames. The flexible folding basket is adhered to the frames. The frames are also provided with casters at their bottom. The cart also includes:
[0005] Bottom support folding assembly: hinged at the connection point between the moving wheel and the frame, and located below the flexible folding basket, for supporting and folding the flexible folding basket;
[0006] Foldable trolley assembly: One end is hinged to the moving wheel and the other end is sleeved on the upper part of the frame, which pushes the flexible folding basket to move and supports it.
[0007] As a preferred embodiment: the foldable trolley assembly includes four sets of fasteners fitted onto the frame, with each pair of fasteners symmetrically extending into a U-shaped hinge interface. A connecting rod is rotatably connected to the hinge interface, and a trolley mechanism is hinged to the end of the connecting rod. The trolley mechanism is hinged to the moving wheels.
[0008] As a preferred embodiment, the trolley mechanism includes an X-shaped folding frame hinged to the moving wheels. Two sets of symmetrical connecting rods are respectively hinged to the upper two ends of the folding frame. A U-shaped sleeve is fitted onto one end of the folding frame. One end of the sleeve is a through hole, and a push handle slides on the through hole end. The push handle and the sleeve are fixed by a pin.
[0009] As a preferred embodiment, the bottom support folding assembly includes a support frame hinged to the moving wheels. Every two sets of moving wheel supports are hinged together by two sets of staggered support frames, and a spring is also connected between the support frames near the inner side.
[0010] As a preferred option four: the frame is also provided with a reinforcing rod, and the flexible folding basket is self-adhesive and fixed after being sleeved on the reinforcing rod.
[0011] The beneficial effects of this utility model by adopting the above structure are as follows:
[0012] 1. The push handle is fixed by telescopic connection between the pin and the sleeve, which allows the push handle to be stored after folding, reducing the space occupied after folding.
[0013] 2. Utilizing the bottom support structure, the flexible folding basket is supported after unfolding and cooperates with the foldable trolley components after folding. Only the lifting spring or support frame is needed to achieve the quick folding effect of the whole vehicle, reducing the difficulty of folding and unfolding the trolley. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0021] Please see Figure 1 , Figure 3 and Figure 4 :
[0022] A foldable portable trolley includes a flexible folding basket 1 for storing items. The flexible folding basket 1 has supporting frames 2 on both sides. The flexible folding basket 1 is glued to the frames 2. The frames 2 also have reinforcing rods 21. The flexible folding basket 1 is self-adhesively fixed after being fitted onto the reinforcing rods 21. The frames 2 also have casters 3 at their bottom. The trolley also includes a bottom support folding assembly 4: hinged at the connection point between the casters 3 and the frames 2, and located below the flexible folding basket 1, used to support and fold the flexible folding basket 1. The folding support assembly 4 includes a support frame 41 hinged to the moving wheels 3. Each pair of moving wheel 3 supports is hinged together by two sets of staggered support frames 41. A spring piece 42 is also connected between the support frames 41 near the inner side. When folding, each pair of support frames 41 is lifted upward around the hinge position, and the spring piece 42 lifts the bottom middle position of the flexible folding basket 1, making it fold upward. The foldable trolley assembly 5 is hinged at one end to the moving wheels 3 and sleeved on the upper part of the frame 2, pushing the flexible folding basket 1 to move and supporting it.
[0023] Please see Figure 1 , Figure 2 , Figure 4-5 :
[0024] The foldable trolley assembly 5 includes four sets of fasteners 51 fitted onto the frame 2. Each pair of fasteners 51 extends symmetrically into a U-shaped hinge interface 52. A connecting rod 53 is rotatably connected to the hinge interface 52. A trolley mechanism 54 is hinged to the end of the connecting rod 53. The trolley mechanism 54 is hinged to the moving wheel 3.
[0025] The trolley mechanism 54 includes an X-shaped folding frame 541 hinged to the movable wheel 3. Two sets of symmetrical connecting rods 53 are respectively hinged to the upper two ends of the folding frame 541. One end of the folding frame 541 is fitted with an 8-shaped sleeve 542. One end of the sleeve 542 is a through hole. A push handle 543 slides on the through hole end. The push handle 543 and the sleeve 542 are fixed by a pin 544.
[0026] Expanded status reference Figure 1 and Figure 3 When folding is required, first press down pin 542 (pin 542 is existing technology, such as the pin on an umbrella pole). After pin 542 is pressed into the push handle 543 and sleeve 542, it loses its restraint on push handle 543. Push push handle 543 down, causing it to extend and retract within sleeve 542. Figure 2 In the state of being in the upper part, the support frame 41 is then lifted. At this time, the connecting rod 53 is hinged and pressed down on the hinge interface 52, and the folding frame 541 folds by hinge, realizing the overall folding operation.
