They are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, specific orientation structure and operation. Therefore, it should not be construed as a limitation to the present invention. In addition, "first" and "second" are only for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, unless otherwise specified, the meaning of "a plurality" is two or more.

[0047] Please refer to Figures 1 to 3As shown in the figure, the present invention provides a single-layer board, which includes a panel 1 and several first reinforcing ribs 2. Two first edge wrappings 11 and two second edge wrappings 12 are provided around the panel 1. Several first reinforcing ribs 2 are arranged on the bottom surface of the panel 1, and multiple first reinforcing ribs 2 are arranged parallel to the first edge wrapping 11.

[0048] Among the above, the panel 1 is a sheet metal part, and the first edge wrapping 11 and the second edge wrapping 12 are formed by bending to improve the structural strength of the panel 1 itself; and by setting several first reinforcing ribs 2 parallel to the first edge wrapping 11, the structural strength of the panel 1 can be further improved, so that the single-layer board has higher structural rigidity and durability.

[0049] Optionally, the connection between the first reinforcing rib 2 and the panel 1 can adopt fixing methods such as gluing, laser welding, riveting, etc., and preferably adopt laser welding, which has the characteristics of stable connection and easy operation.

[0050] Preferably, the ends of the first edge wrapping 11 and the second edge wrapping 12 are fixedly connected by laser welding to further enhance the structural stability of the panel 1.

[0051] In a preferred embodiment, referring to Figure 1 , there are two first reinforcing ribs 2. One side of the first reinforcing rib 2 abuts against the inner side of one of the first edge wrappings 11. On the one hand, it can improve the structural strength of the first edge wrapping 11 to prevent the first edge wrapping 11 from deforming. On the other hand, it can improve the structural strength of the single-layer board in the direction where the first edge wrapping 11 is located; the end of the first reinforcing rib 2 abuts against the inner side of the second edge wrapping 12. The end of the first reinforcing rib 2 plays an auxiliary supporting role for the second edge wrapping 12 to ensure that the second edge wrapping 12 and the panel 1 remain perpendicular to each other to prevent the second edge wrapping 12 from deforming.

[0052] Referring to Figures 5 - 9 , the first reinforcing rib 2 includes a horizontal portion 21 and a first vertical portion 22 which are perpendicularly arranged. The horizontal portion 21 is arranged on the bottom surface of the panel 1, and the first vertical portion 22 is attached to the inner side of the first edge wrapping 11. At least one first convex rib 23 is arranged on the horizontal portion 21. Since the horizontal portion 21 and the first vertical portion 22 are perpendicularly arranged and the first vertical portion 22 is attached to the inner side of the first edge wrapping 11, it plays an auxiliary supporting role for the first edge wrapping 11 to ensure that the first edge wrapping 11 and the panel 1 remain perpendicular to each other and prevent the first edge wrapping 11 from deforming.

[0053] In this embodiment, preferably, there is one first raised rib 23. By providing the first raised rib 23, the structural strength of the first reinforcing rib 2 can be improved. It should be understood that the number of the first raised ribs 23 can be determined according to actual requirements. The more the number of the first raised ribs 23, the higher the structural strength. Correspondingly, the width dimension thereof is also larger, and more materials are required.

[0054] In the above, the first reinforcing rib 2 is a sheet metal part, and a cross-section with a specific shape is formed by a bending and forming method, which has the characteristics of easy processing, high structural strength, and light weight.

[0055] The first raised rib 23 includes a first side 231, a second side 232, and a third side 233 that are connected in sequence, and the second side 232 is parallel to the horizontal part 21.

[0056] In one embodiment, as Figure 5 、 6 、7 shows, the first side 231 is inclined, the third side 233 is perpendicular to the horizontal part 21, or the first side 231 is perpendicular to the horizontal part 21, and the second side 232 is inclined to form a right trapezoidal structure without a bottom side; both the first side 231 and the second side 232 are inclined to form an isosceles trapezoidal structure without a bottom side. When a through hole 25 is provided on the horizontal part 21 and the through hole 25 is connected to other fittings by fasteners, by providing the inclined first side 231 and / or the second side 232, a larger space can be provided to avoid the tools used, which is convenient for using tools to operate the fasteners.

[0057] In another embodiment, as Figure 8 shows, the first side 231 and the third side 233 are respectively perpendicular to the horizontal part 21 to form a rectangular structure without a bottom side.

[0058] In a preferred embodiment, a first flanging 24 is provided on the first vertical part 22, and the first flanging 24 is perpendicular / parallel to the first vertical part 22. As Figure 5 shows, the first flanging 24 is perpendicular and parallel to the first vertical part 22, that is, after assembly, the first vertical part 22 and the first flanging 24 are respectively attached to the inner side of the first edge folding 11, thereby improving the structural strength of the first edge folding 11. As Figure 9 shows, the first flanging 24 is parallel to the first vertical part 22, which can prevent the second vertical part 121 from scratching hands.

[0059] In a preferred embodiment, referring to Figure 2 , it further includes a plurality of second reinforcing ribs 3 provided on the bottom surface of the panel 1, and the second reinforcing ribs 3 are arranged in parallel with the first reinforcing ribs 2. When the length / width of the panel 1 is relatively long, that is, in the length direction of the second edge folding 12, a certain number of second reinforcing ribs 3 can be added to further improve the structural strength of the single-layer board so as to improve its load-bearing capacity.

[0060] Preferably, the structure of the second reinforcing rib 3 is similar to that of the first reinforcing rib 2. For its specific structure, reference can be made to the above-mentioned first reinforcing rib 2, which will not be elaborated here.

[0061] In a preferred embodiment, referring to Figure 4 , the first edge wrap 11 has an "L" - shaped structure. This can improve the strength of the first edge wrap 11 and facilitate the first vertical portion 22 of the first reinforcing rib 2 to penetrate into the inner side of the first edge wrap 11, realizing the fitting installation of the first vertical portion 22 and the first edge wrap 11.

[0062] Furthermore, the first edge wrap 11 includes a second turned - up edge 111. As shown in Figure 10 , the second turned - up edge 111 is parallel to the panel 1; as shown in Figure 11 , the second turned - up edge 111 is perpendicular to the panel 1. Through the above - mentioned settings, the structural strength of the edge position of the first edge wrap 11 is further enhanced, and at the same time, it can avoid the first edge wrap 11 from scratching hands, improving the safety when grasping the single - layer board.

[0063] In a preferred embodiment, referring to Figures 12 - 17 , the second edge wrap 12 includes a second vertical portion 121, a first bending portion 122, and a first fixing portion 123 connected in sequence. The second vertical portion 121 is perpendicular to the panel 1, and the first fixing portion 123 is in contact with the bottom surface of the second vertical portion 121 / panel 1. By providing the second vertical portion 121, the first bending portion 122, and the first fixing portion 123, the second vertical portion 121 and the first bending portion 122 enclose a closed area, or the second vertical portion 121, the first bending portion 122, and the panel 1 enclose a closed area, which can further improve the strength of the single - layer board in the direction where the second edge wrap 12 is located. In this direction, there is no need to set additional reinforcing ribs to improve the structural strength in this direction, effectively reducing the number of reinforcing ribs used and meeting the material - saving and product lightweight design requirements. In addition, the second edge wrap 12 is perpendicular to the first reinforcing rib 2 and the second reinforcing rib 3, which can hide the ends of the first reinforcing rib 2 and the second reinforcing rib 3, improving the appearance beauty of the single - layer board.

[0064] Optionally, between the first fixing portion 123 and the second vertical portion 121, and between the first fixing portion 123 and the panel 1, fixing methods such as gluing, laser welding, riveting, etc. can be adopted. Preferably, the laser welding method is adopted, which has the characteristics of stable connection and easy operation.

[0065] In the above - mentioned embodiment, when the first fixing portion 123 and the second vertical portion 121 are in contact, the first bending portion 122 and the second vertical portion 121 enclose a closed area, as shown in Figure 13 , 14As shown, the closed area is a rectangle, a right trapezoid, or other regular / irregular figures. Through the above settings, the structural strength of the lower part of the second edge wrapping 12 can be improved.

[0066] In the above embodiment, when the first fixing part 123 is attached to the panel 1, the second vertical part 121, the first bending part 122, and the panel 1 enclose a closed area, such as Figure 12 , 15 , 16, 17. The closed area is a rectangle, an isosceles trapezoid, or other regular / irregular figures. Through the above settings, the structural strength of the entire second edge wrapping 12 can be improved.

[0067] It should be noted additionally that referring to Figure 2 , 3 , the end of the first reinforcing rib 2 is set to abut against the inner side of the second edge wrapping 12. Specifically, the first bending part 122 and the first fixing part 123 are provided with notches 13 for avoiding the end of the first reinforcing rib 2, so that the end of the first reinforcing rib 2 abuts against the second vertical part 121, and the edge of the notch 13 is fixedly connected to the surface of the second reinforcing rib 3, further enhancing the auxiliary supporting effect of the first reinforcing rib 2 on the second edge wrapping 12. The above fixed connection method is preferably laser welding.

[0068] In a preferred embodiment, the first bending part 122 includes a first bending edge 1221 and a second bending edge 1222, and the first bending edge 1221 is perpendicular to the second vertical part 121. Specifically, as Figure 12 shown, the second bending edge 1222 can be a straight edge, that is, the second bending edge 1222 is perpendicular to the first bending edge 1221; the second bending edge 1222 can be an inclined edge, that is, the included angle between the second bending edge 1222 and the first bending edge 1221 is greater than 90°.

[0069] Furthermore, a second raised rib 1223 is provided on the second bending edge 1222, and the second raised rib 1223 faces the direction of the second vertical part 121. Among them, the second raised rib 1223 is integrally bent and formed with the second edge wrapping 12. Specifically, as Figures 15 - 17 shown, the shape of the first raised rib 23 can be a semi-circular shape without a bottom edge, a rectangle, an isosceles trapezoid, a right trapezoid, or other regular / irregular figures. By providing the first raised rib 23, the structural strength of the first vertical part 22 can be enhanced and it is not easy to deform. Even during production, transportation, and use, if it collides with the second edge wrapping 12 due to misoperation, it is not easy to deform.

[0070] In this embodiment, it is preferred that the second bending edge 1222 is a straight edge, so that while the second edge wrapping 12 has high structural strength, it is also easy to process and saves materials.

[0071] In a preferred embodiment, referring toFigure 2 , 19 , a first connection hole 4 is provided on the first edge wrap 11 and / or the second edge wrap 12. The first connection hole 4 can be connected and fixed to other single-layer boards through fasteners to assemble into a cabinet body. Specifically, a second connection hole 14 is provided on the panel 1, and the second connection hole 14 of one single-layer board is connected to the first connection hole 4 of another single-layer board through fasteners to realize the perpendicular installation of two single-layer boards to each other.

[0072] Specifically, referring to Figure 4 , the first connection hole 4 is located on the first edge wrap 11, and a mounting hole 41 is punched on the first vertical part 22 of the first reinforcing rib 2. Threads are provided in the mounting hole 41, and the connection between other single-layer boards and the first edge wrap 11 of this single-layer board can be realized by means of screw connection.

[0073] Specifically, referring to Figure 19 , the first connection hole 4 is located on the second edge wrap 12, and a nut is fixed on the first connection hole 4. The mounting method of the nut can be laser welding or riveting, and the connection between other single-layer boards and the second edge wrap 12 of this single-layer board can be realized by means of screw connection. Through the above settings, the difficulty of assembling multiple single-layer boards is greatly reduced, thereby improving the assembly efficiency.

[0074] Referring to Figures 20 - 24 , the present invention also provides a cabinet body, including two side plates 5 arranged in parallel, a bottom plate 6 for connecting the two side plates 5, a back plate 7 for connecting the two side plates 5 and the bottom plate 6, and several intermediate plates 8 arranged in parallel with the bottom plate 6. The side plates 5, the bottom plate 6, the back plate 7, and the intermediate plates 8 are all the above-mentioned single-layer boards. The single-layer board can be used as the side plate 5, the bottom plate 6, the back plate 7, and the intermediate plate 8. It has strong versatility, is easy to assemble, is suitable for industrial production, and can effectively reduce labor costs.

[0075] Referring to Figure 20 , 21, to further improve the connection stability between the two side plates 5, it further includes a pull rod 9 and end caps 10 provided at both ends of the pull rod 9. Threaded holes 101 are provided on the end caps 10, and the side plates 5 are connected to the end caps 10 through fasteners, so that the pull rod 9 can connect the upper parts of the front sides of the two side plates 5, thereby improving the structural stability of the front side of the cabinet body.

[0076] The pull rod 9 is a sheet metal part, which is formed into a specific cross-sectional shape by bending, and has the characteristics of easy processing, high structural strength, and light weight. The pull rod 9 includes a middle plane 91 and second bending parts 92 symmetrically arranged on the middle plane 91. The second bending parts 92 include mounting parts 921 and second fixing parts 922. The area enclosed by the mounting part 921 and the middle plane 91 forms an insertion hole 93, and the second fixing part 922 is attached to the middle plane 91. Specifically, the second fixing part 922 is fixedly connected to the middle plane 91 by welding, gluing, riveting or other means to ensure the structural stability of the pull rod 9.

[0077] Specifically, as Figure 23 , 24 shown, the shape of the insertion hole 93 is rectangular or right trapezoidal.

[0078] Referring to Figure 21 , 22 , two clamping parts 102 are provided on the end cover 10. One clamping part 102 is correspondingly installed into one insertion hole 93, and a fastening component 20 is provided between the clamping part 102 and the insertion hole 93. The fastening component 20 includes a clamping block 201 provided on the clamping part 102 and a clamping hole 202 provided on the side wall of the insertion hole 93. The clamping block 201 is fastened to the clamping hole 202, and an inclined guiding surface 203 is provided on the top surface of the clamping block 201. Through the guiding surface 203, it is beneficial for the clamping hole 202 to be fastened to the clamping block 201.
