Example
[0029] This embodiment provides a cover 100 for a military multi-layered packaging box.
[0030] Among them, reference Figure 1 and Figure 2 As shown, the lower surface of the cover 100 is recessed inward to form a receiving groove 110. The receiving groove 110 is generally trapezoidal in shape, and its area gradually decreases along the direction near the bottom of the groove. When used with the box, the trapezoidal receiving groove 110 not only provides a certain storage space, but also facilitates the stacking of multiple covers 100 during the production process, saving space.
[0031] like Figure 1 and Figure 3 As shown, the lower edge of the cover 100 has an outwardly protruding cover edge 120, which surrounds the lower edge of the cover 100. The cover 100 includes two end walls 130 at both ends along its length. Each end wall 130 has a plurality of first reinforcing ribs 131. The first reinforcing ribs 131 are arranged vertically to connect the upper surfaces of the end walls 130 and the cover edge 120. The plurality of first reinforcing ribs 131 are spaced apart along the width of the cover 100. The upper surfaces of the plurality of first reinforcing ribs 131 are all horizontal and on the same horizontal plane, namely the first horizontal plane 1311, which abuts against the lower surface of the cover edge 120 of the other cover 100. The first reinforcing ribs 131 not only strengthen the overall strength of the cover 100, but also serve as supports for the other cover 100 when stacked, forming a more stable stack.
[0032] Furthermore, the upper surface of the cover 100 is provided with four stacking blocks 140, which are symmetrically arranged at the four corners of the cover 100. Correspondingly, four stacking slots are provided at the bottom of the box to match the four stacking blocks 140. The stacking blocks 140 and the stacking slots can form a stacking positioning, ensuring the stability of the military multi-overlap packaging box when stacked. The supporting structure of the four stacking blocks 140 allows the cover 100 to perfectly match the box even when rotated 180 degrees on the horizontal plane, increasing the convenience of stacking.
[0033] The upper surfaces of the four stacking blocks 140 are horizontally positioned and on the same horizontal plane, namely the second horizontal plane 141, to abut against the bottom of the receiving groove 110 of another cover 100. When the covers 100 are stacked together, the four stacking blocks 140 can support the bottom of the groove of the upper cover 100, providing a new support point in addition to the support of the first reinforcing rib 131. Moreover, the new support point is located inside the cover 100, which can provide support for the interior of the cover 100 and prevent internal collapse.
[0034] Furthermore, such as Figure 4 and Figure 5 As shown, the distance from the first horizontal plane 1311 to the lower edge of the cover edge 120 is equivalent to the distance from the second horizontal plane 141 to the bottom of the receiving groove 110. Thus, when the upper surface of the first reinforcing rib 131 abuts against the lower surface of the cover edge 120 of the upper cover 100, the upper surfaces of the four stacked blocks 140 abut against the bottom of the groove of the upper cover 100, thus providing support.
[0035] In addition, such as Figure 1 and Figure 5 As shown, the cover 100 includes two sidewalls 150 disposed on both sides along its length. Each sidewall 150 is provided with a locking portion 151 for engaging with the body of a military multi-layered packaging box. Protective ridges 152 are provided on both sides of the locking portion 151. The protective ridges 152 protrude horizontally outward from the sidewall 150 and the cover edge 120, extending beyond the locking portion 151. The upper surface of the protective ridge 152 is coplanar with the first horizontal plane 1311. The upper surface of the protective ridge 152 can form new support points, strengthening the support for the sidewalls 150 of the cover 100. When multiple covers 100 are stacked, the upper surface of the protective ridge 152, in conjunction with the first reinforcing rib 131, can simultaneously support the lower surface of the cover edge 120 of the upper cover 100.
[0036] The side wall 150 is also provided with a plurality of second reinforcing ribs 153. The second reinforcing ribs 153 are arranged vertically to connect the upper surface of the side wall 150 and the cover edge 120. The plurality of second reinforcing ribs 153 are spaced apart along the length of the cover body 100. The second reinforcing ribs 153 mainly serve a reinforcing function and do not require support. Therefore, the top of the second reinforcing ribs 153 is lower than the first horizontal plane 1311.
[0037] Furthermore, such as Figure 6As shown, the bottom of the receiving groove 110 is staggered with multiple transverse reinforcing ribs 111 and multiple longitudinal reinforcing ribs 112. These staggered reinforcing ribs increase the overall strength of the cover 100. The bottom of the receiving groove 110 also has a first oblique reinforcing rib 113 and a second oblique reinforcing rib 114. The first oblique reinforcing rib 113 extends from the projection position of the stacked block 140 on the bottom of the groove to the corner of the bottom closest to the stacked block 140. The second oblique reinforcing rib 114 extends from the projection position of the stacked block 140 on the bottom of the groove to the middle of the end wall 130 closest to the stacked block 140. Because the stacked block 140 alters the stress distribution of the cover 100, increasing the stress at the four corners of the cover 100, the first oblique reinforcing rib 113 and the second oblique reinforcing rib 114 strengthen the four corners of the bottom of the receiving groove 110, extending the service life of the cover 100.
[0038] In summary, this utility model embodiment provides a cover 100 for a military multi-layered packaging box. The lower surface of the cover 100 is recessed to form a receiving groove 110. The receiving groove 110 is generally trapezoidal in shape, and its area gradually decreases along the direction close to the bottom of the groove. The lower edge of the cover 100 is provided with an outwardly protruding cover edge 120, which surrounds the lower edge of the cover 100. The cover 100 includes two end walls 130 at both ends in its length direction. The end walls 130 are provided with a plurality of first reinforcing ribs 131. The first reinforcing ribs 131 are arranged vertically to connect the upper surfaces of the end walls 130 and the cover edge 120. The plurality of first reinforcing ribs 131 are spaced apart along the width direction of the cover 100. The upper surfaces of the plurality of first reinforcing ribs 131 are all horizontally arranged and are on the same horizontal plane, i.e., the first horizontal plane 1311, for abutting against the lower surface of the cover edge 120 of the other cover 100. The first reinforcing rib 131 not only strengthens the overall strength of the cover 100, but also serves as a support for another cover 100 when stacked, forming a more stable stack.
[0039] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
