[0002] A storage rack is a device for placing and storing items, and is commonly used in scenarios such as families, stores, and warehouses. There is a grid-type metal storage rack on the market now, which has the advantages of light weight, small steel consumption, and convenient batch manufacturing. However, the load-bearing capacity of the grid is poor. Therefore, in the existing grid-type storage racks, a support structure is usually added to the grid to improve the load-bearing capacity of the grid, but this will cause the volume of the grid to increase, which is not conducive to the packaging and transportation of the grid-type storage rack after disassembly. Content of the Utility Model

[0003] The purpose of the utility model is to provide a high-strength support grid for a metal storage rack. The grid is formed by successively hinging a plurality of mesh plate units in the left-right direction to form a grid for supporting items. Thus, the volume of the grid can be reduced by rotating the mesh plate units to the vertical state so that adjacent mesh plate units are attached to each other, which is conducive to the packaging and transportation of the grid.

[0004] The technical solution adopted by the utility model to solve the above problems is as follows:

[0005] A high-strength support grid for a metal storage rack includes support rods and a grid. A plurality of the grids are arranged at intervals up and down, and a plurality of the support rods are arranged in a vertical state. The grids are all connected to the support rods and arranged between a plurality of support rods. The grid unit includes a plurality of mesh plate units, and the plurality of mesh plate units are successively hinged in the left-right direction.

[0006] In the above technical solution, preferably, the mesh plate unit includes a first mesh plate, a second mesh plate, and a third mesh plate. The first mesh plate, the second mesh plate, and the third mesh plate are all hinged by a plurality of three-piece hinges on the same axis in the front-rear direction. The adjacent first mesh plate and second mesh plate in the adjacent left and right mesh plate units are hinged.

[0007] In the above technical solution, preferably, four support rods are provided. The horizontal section of the grid is rectangular. The support rods are arranged on the front and rear sides of the grid, and the four support rods are respectively close to the four corners of the grid.

Detailed Embodiment

[0019] The present utility model will be further described in detail below in conjunction with the accompanying drawings and through embodiments. The following embodiments are explanations of the present utility model, and the present utility model is not limited to the following embodiments.

[0020] See Figures 1-5 , in this embodiment, a high-strength support grid for a metal storage rack includes support rods 1 and a grid 2. A plurality of grids 2 are arranged at intervals up and down, and a plurality of support rods 1 are arranged vertically. The grids 2 are all connected to the support rods 1 and arranged between several support rods 1. The grid 2 unit includes several net plate units 21, and the several net plate units 21 are sequentially hinged and connected in the left-right direction.

[0021] In the present utility model, by arranging the grid 2 inside the support rod 1, the grid 2 plays a supporting role, so that the user can place items on the grid 2 to realize the storage function of the present utility model. Since the several net plate units 21 in the grid 2 unit are sequentially hinged and connected in the left-right direction, the net plate units 21 can be rotated and then sequentially staggered and folded in the left-right direction, so that the moment of inertia of the overall grid 2 increases, thereby improving the load-bearing capacity of the grid 2. And by rotating the net plate units 21 to the vertical state, the adjacent net plate units 21 can be attached and stacked (as shown in Figure 4 ), so that the overall volume of the grid 2 is reduced, which is beneficial to the packaging and transportation of the grid 2.

[0022] See Figure 2 , Figure 3 , the net plate unit 21 includes a first net plate 22, a second net plate 23 and a third net plate 24. The first net plate 22, the second net plate 23 and the third net plate 24 are hinged and connected by a plurality of three-piece hinge joints 25 on the same axis in the front-rear direction. The adjacent first net plate 22 and second net plate 23 in the left-right adjacent net plate units 21 are hinged and connected.

[0023] When the grid 2 is produced and installed, first, the first net plate 22, the second net plate 23 and the third net plate 24 are assembled together through the three-piece hinge joint 25 to form the net plate unit 21 in one station, and then the first net plate 22 and the second net plate 23 in the two net plate units 21 are connected by hinging in the next station to realize the assembly of the grid 2. It has the advantage of simple assembly method and can achieve the purpose of folding installation and stacking storage of the grid 2.

[0024] See Figure 5 , the three-piece hinge joint 25 includes a first hinge 26, a second hinge 27 and a third hinge 28. The first hinge 26 is fixedly connected to the first net plate 22, the second hinge 27 is fixedly connected to the second net plate 23, and the third hinge 28 is fixedly connected to the third net plate 24.

[0025] SeeFigure 1 , Figure 2 , there are four support rods 1 provided. The horizontal cross-section of the grid 2 is rectangular. The support rods 1 are arranged on the front and rear sides of the grid 2 and the four support rods 1 are respectively close to the four corners of the grid 2. Horizontal crossbars 11 in the left-right direction are arranged on both the front and rear sides of the grid 2. The two ends of the crossbar 11 are detachably fixed to the support rods 1 correspondingly, and the grid 2 is installed on the crossbar 11.

[0026] When the mesh panel unit 21 is in use, the third mesh panel 24 rotates to a horizontal state. The first mesh panel 22 and the second mesh panel 23 are located below the third mesh panel 24 to support the third mesh panel 24. And the lower ends of the first mesh panel 22 and the second mesh panel 23 are fixed between the crossbars 11 to form a triangular stable structure, which can improve the stability of the grid 2 and reduce the situation that the grid 2 loses its supporting effect due to loosening and rotation between the mesh panel units 21. The two ends of the crossbar 11 are detachably fixed to the support rods 1 correspondingly, which is convenient for packaging and transportation after the crossbar 11 and the support rods 1 are disassembled.

[0027] See Figure 3 , a plurality of installation grooves 12 are formed on the crossbar 11. The upper end of the first mesh panel 22, the upper end of the second mesh panel 23 and the left end of the third mesh panel 24 are hingedly connected through a three-piece hinge 25. The front and rear ends of the lower ends of the first mesh panel 22 and the second mesh panel 23 are inserted into the adjacent installation grooves 12, and the right end of the third mesh panel 24 is placed on the hinge shaft where the three-piece hinge 25 is located in the adjacent mesh panel unit 21.

[0028] When installing the grid 2 onto the crossbar 11, the lower ends of the first mesh panel 22 and the second mesh panel 23 in the mesh panel unit 21 are sequentially inserted into the installation grooves 12. The installation grooves 12 play a limiting role in the left-right direction for the lower ends of the first mesh panel 22 and the second mesh panel 23, so that a triangular structure can be formed among the first mesh panel 22, the second mesh panel 23 and the crossbar 11, which has good stability. At the same time, the position of the installation grooves 12 can also play a positioning role during the installation of the grid 2, improving the convenience of installing the grid 2. The distance between adjacent installation grooves 12 should be less than the left-right width of the third mesh panel 24 to ensure that the third mesh panel 24 can be placed on the hinge shaft where the three-piece hinge 25 is located in the adjacent mesh panel unit 21. When removing the grid 2 from the crossbar 11, only need to pull out the lower ends of the first mesh panel 22 and the second mesh panel 23 from the installation grooves 12 upwards, which has the advantage of simple operation.

[0029] See Figure 2 , support columns 13 are arranged on the inner sides of the two support rods 1 on the right side. The right end of the third mesh panel 24 in the rightmost mesh panel unit 21 is placed on the support column 13.

[0030] The support column 13 can support the third net plate 24 at the rightmost end inside the net rack 2, enabling the third net plate 24 to also have the function of carrying items and increasing the area of the net rack 2 for carrying items.

[0031] See Figure 3 , the first net plate 22, the second net plate 23, and the third net plate 24 have the same size and specifications, which is convenient for mass-producing net plates of the same specification. Then, the three net plates are installed through a three-piece hinge 25 to form a net plate unit 21. Therefore, when manufacturing this utility model, it is not necessary to adjust the parameters of the manufacturing equipment or prepare multiple sets of molds, which can reduce the manufacturing difficulty and production cost of this utility model.

[0032] The above content described in this specification is only an example of this utility model. Those skilled in the technical field to which this utility model belongs can make various modifications, supplements, or use similar methods to replace the specific embodiments described, as long as they do not deviate from the content of this specification or exceed the scope defined by this claim book, they should fall within the protection scope of this utility model.
