[0045] In addition to the above, it should be emphasized that the reference to "embodiment" herein means that a specific feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will understand, explicitly and implicitly, that the embodiments described herein can be combined with other embodiments.

[0046] Figure 1 The diagram shows a handcart, including a push-pull handle, a storage frame, and transport wheels. The storage frame is surrounded by a mesh panel structure. This handcart provides good ventilation and light transmission, and makes it more portable. Figure 2 The diagram shows a schematic of a prior art mesh panel structure, including a mesh panel and steel pipes surrounding the mesh panel. Figure 2 Figure 1 shows a groove cut into the steel pipe near the mesh panel, with the mesh panel extending into the groove and welded to the steel pipe. Figure 3 shows the bottom of the mesh panel structure after the steel pipe and mesh panel are combined, and then sealed. Therefore, during outdoor use, rainwater will accumulate inside the bottom steel pipe and is difficult to drain, making it extremely prone to rusting.

[0047] To address the aforementioned technical problems, this utility model proposes a novel mesh panel structure, such as... Figure 5 As shown, it includes a mesh panel 1, a mesh panel fastener 2, and a bottom fastener 3.

[0048] In one specific embodiment, such as Figure 5 As shown, the mesh panel 1 has a diamond-shaped grid structure, which disperses force when the panel is under stress, enhancing the overall structural stability and making it less prone to damage from localized stress. Furthermore, the grid pattern provides good ventilation and light transmission, and makes the handcart lighter.

[0049] In one specific embodiment, such as Figures 5-6 As shown, the mesh panel fixing component 2 includes a transverse steel pipe fixing component 21 fixed to the upper edge of the mesh panel 1, and two longitudinal steel pipe fixing components 22 on the left and right side edges. In one specific embodiment, as... Figure 5 As shown in the figure, the transverse steel pipe fastener 21 and the two longitudinal steel pipe fasteners 22 have grooves cut into the side walls of the steel pipes near the mesh plate 1. The mesh plate 1 extends into the grooves and is welded together. The assembled structure is as follows: Figure 12 As shown in the image.

[0050] In one specific embodiment, such as Figures 5-8 As shown, the bottom fixing member 3 includes a first L-shaped steel plate member 31 and a second L-shaped steel plate member 32. Specifically, Figure 7The structure of the first L-shaped steel plate member 13 is shown. The first L-shaped steel plate member 31 includes a first vertical web 311 and a first horizontal wing 312; the first vertical web 311 and the first horizontal wing 312 are arranged vertically. Figure 8 The structure of the second L-shaped steel member 32 is shown. The second L-shaped steel member 32 includes a second vertical web 321 and a second horizontal flange 322, which are arranged perpendicularly. Figure 6 As shown, the surfaces of the first vertical web 311 and the second vertical web 321 are parallel to each other, and the lower ends of the two longitudinal steel pipe fasteners 22 are fixed between the first vertical web 311 and the second vertical web 321; the first horizontal wing 312 and the second horizontal wing 322 extend towards each other, and a mesh groove 5 is formed between the first horizontal wing 312 and the second horizontal wing 322, and the lower end of the mesh plate 1 is inserted into the mesh groove 5.

[0051] In one specific embodiment, such as Figures 6-7 In the middle, the part where the first vertical web 311 contacts the longitudinal steel pipe fixing member 22 does not have a first horizontal flange 312; for example Figure 6 and 8 In this configuration, the second horizontal wing plate 322 is not provided at the part where the second vertical web plate 321 contacts the longitudinal steel pipe fixing member 22. While the lower ends of the two longitudinal steel pipe fixing members 22 are fixed between the first vertical web plate 311 and the second vertical web plate 321, the surfaces of the first horizontal wing plate 312 and the second horizontal wing plate 322 are perpendicular to the longitudinal steel pipe fixing member 22, thereby achieving lateral limitation of the longitudinal steel pipe fixing member 22.

[0052] In one specific embodiment, such as Figure 9 In this configuration, the lower end of the longitudinal steel pipe fixing member 22 is fixed between the first vertical web 311 and the second vertical web 321 by bolts. Specifically, the lower end of the longitudinal steel pipe fixing member 22 is provided with a threaded hole penetrating the longitudinal steel pipe fixing member 22, and the threaded hole is axially perpendicular to the mesh plate 1; the first vertical web 311 and the second vertical web 321 are provided with corresponding threaded holes; a bolt passes through the second vertical web 321, the longitudinal steel pipe fixing member 22, and the first vertical web 311 in sequence.

[0053] In one specific embodiment, such as Figures 6-7 As shown, the mesh support 4 is fixed to the side of the first vertical web 311 near the second vertical web 321, providing upward support to the lower end of the mesh 1 passing through the mesh groove 5, further ensuring the stability of the mesh structure. Optionally, the mesh support 4 can be a sheet material, an L-shaped plate, or other structure that can provide upward support to the lower end of the mesh 1.

[0054] In one specific embodiment, such as Figure 7 In the middle, the mesh support member 4 is an L-shaped plate, including a vertical web and a horizontal wing plate; the plate surface of the vertical web is fixed on the plate surface of the first vertical web 311, and the horizontal wing plate extends in a direction close to the second horizontal wing plate 322 to support the lower end of the mesh 1 passing through the mesh groove 5.

[0055] In another specific embodiment, the mesh support 4 is a plate, one end of which is fixed to the plate surface of the first vertical web 311, that is, the plate surface extends in the direction close to the second vertical web 321, and is used to support the lower end of the mesh 1 passing through the mesh groove 5.

[0056] In one specific embodiment, such as Figures 5-6 As shown, it also includes one or more intermediate longitudinal fasteners 6, such as Figure 10 As shown, the intermediate longitudinal fixing member 6 includes a first concave steel plate 61 and a second concave steel plate 62, with the concave surfaces of the first concave steel plate 61 and the second concave steel plate 62 arranged in a mirror-symmetrical manner. The upper ends of the first concave steel plate 61 and the second concave steel plate 62 are fixedly connected to the transverse steel pipe fixing member 21. The lower ends of the first concave steel plate 61 and the second concave steel plate 62 are fixed between the first vertical web plate 311 and the second vertical web plate 321. Specifically, the part of the first vertical web plate 311 that contacts the intermediate longitudinal fixing member 6 does not have a first horizontal wing plate 312, and the part of the second vertical web plate 321 that contacts the intermediate longitudinal fixing member 6 does not have a second horizontal wing plate 322. While the lower end of the intermediate longitudinal fixing member 6 is fixed between the first vertical web plate 311 and the second vertical web plate 321, the surfaces of the first horizontal wing plate 312 and the second horizontal wing plate 322 are perpendicular to the intermediate longitudinal fixing member 6, thereby achieving lateral limitation of the intermediate longitudinal fixing member 6.

[0057] In one specific embodiment, the lower ends of the first concave steel plate 61 and the second concave steel plate 62 are fixed between the first vertical web 311 and the second vertical web 321, as shown below. Figures 10-11 In the mesh plate 1, the lower ends of the first concave steel plate 61 and the second concave steel plate 62 are respectively provided with screw holes penetrating the first concave steel plate 61 and the second concave steel plate 62, and the screw holes are axially perpendicular to the mesh plate 1; the first vertical web plate 311 and the second vertical web plate 321 are provided with corresponding screw holes; a bolt passes through the second vertical web plate 321, the first concave steel plate 61, the second concave steel plate 62 and the first vertical web plate 311 in sequence.

[0058] In one specific embodiment, the cross-section of the transverse steel pipe fixing member 21 is circular or square. In a preferred specific embodiment, such as... Figures 5-12 As shown, the cross-section of the transverse steel pipe fastener 21 is square.

The storage frame includes a base plate and the novel mesh structure provided in Embodiment 1. The novel mesh structure is detachably or fixedly connected to the base plate. The connection method can be one of the commonly used connection methods such as bolt connection, snap-fit ​​connection, and hinge connection.

[0061] Preparation Example 1

[0062] The fabrication process of the novel mesh structure provided in Example 1 is as follows:

[0063] Step 1: Provide mesh panel 1 and mesh panel fasteners 2, and assemble them. The specific assembly method is as follows: the horizontal steel pipe fastener 21 and the two longitudinal steel pipe fasteners 22 have grooves cut into the side walls of the steel pipes near the mesh panel 1. The mesh panel 1 extends into the grooves and is welded together, as shown in the structure. Figure 12 As shown in the image, the entire assembly is then powder-coated to obtain component A, as shown. Figure 12 As shown;

[0064] Step 2: Provide the first L-shaped steel plate component 31 and the mesh support component 4, and assemble them. Specifically, the assembly method is as follows: weld the mesh support component 4 to the side of the first vertical web 311 near the second vertical web 321, and then perform overall powder coating treatment to obtain component B, as shown below. Figure 7 As shown;
