The side connecting plate 14 includes a first side connecting part 121, a second side connecting part 122, and a third side connecting part 123 that are sequentially connected to the bottom plate 11. A first side connecting part 141, a second side connecting part 142, and a third side connecting part 143 are connected in sequence. The third side connecting part 143, the second side connecting part 142, and the first side connecting part 141 are folded in sequence toward the bottom plate 11 to form a side plate 2140. The lower connecting plate 15 includes a first lower connecting part 151, a second lower connecting part 152, a third lower connecting part 153, and a fourth lower connecting part 154 that are connected in sequence to the bottom plate 11. The first lower connecting part 151, the second lower connecting part 152, the third lower connecting part 153, and the fourth lower connecting part 154 are folded vertically toward the bottom plate 11 to form a lower folding block 2120. The fourth lower connecting part 154 abuts against the bottom plate 11. The two ends of the first lower connecting part 151 are connected to lower insert plates 1511, and the two lower insert plates 1511 are respectively inserted into the side folding block 2110 and the side plate 2140.

[0042] like Figure 7 As shown, the outer side of the third side connecting part 133 and the outer side of the second side connecting part 142 are respectively provided with a retaining strip 17, and the bottom plate 11 is respectively provided with a slot 111 that engages with the corresponding retaining strip 17; this arrangement can improve the firmness of the connection between the side folding block 2110, the side plate 2140 and the bottom plate 11, and improve the strength of the inner lining side plate 2100.

[0043] like Figure 4 As shown, in one embodiment, folding frames are provided on both sides of the inner cavity of the lower folding block 2120.

[0044] like Figure 4 , 7 As shown, the folding frame is formed by folding the folding frame plate 16. The folding frame plate 16 is opened on the lower connecting plate 15 and close to the bottom plate 11. Specifically, the folding frame plate 16 is the folding frame plate 16 opened in the middle of the first lower connecting part 151 along the length direction. The two folding frames are symmetrically distributed with respect to the center of the first lower connecting part 151.

[0045] Specifically, the folding frame 16 includes a first folding frame portion 161 and a second folding frame portion 162 connected sequentially from the outside to the inside on the first lower connecting portion 151; the second folding frame portion 162 and the first folding frame portion 161 are folded vertically toward the side plate 2140 in sequence to form an L-shaped folding frame, or the second folding frame portion 162 and the first folding frame portion 161 are folded vertically toward the side folding block 2110 in sequence to form an L-shaped folding frame. The space enclosed by the two folding frames within the lower folding block 2120 can be used to place accessories such as the power cord of the display 4.

[0046] like Figure 3 As shown in one embodiment, a reinforcing block 2170 is embedded in the inner cavity of the side folding block 2110.

[0047] like Figure 3 , 8 As shown, the reinforcing block 2170 is formed by folding the reinforcing folded plate 2. The reinforcing folded plate 2 includes reinforcing base plates 21 connected in sequence. Multiple reinforcing base plates 21 are folded end to end to form a rectangular reinforcing block 2170. The reinforcing block 2170 is adapted to the inner cavity of the side folding block 2110. After the side connecting plate 13 is folded to form the side folding block 2110, the reinforcing block 2170 can be inserted into the upper and lower openings of the side folding block 2110. Alternatively, before the side connecting plate 13 is folded to form the side folding block 2110, the reinforcing block 2170 can be placed on the side of the base plate 11 near the side connecting plate 13, so that after the side folding block 2110 is folded into shape, the reinforcing block 2170 is located in the cavity of the side folding block 2110, thereby improving the strength of the inner lining side plate 2100.

[0048] like Figure 5 , 8 As shown, this embodiment has 11 reinforcing base plates 21. Each of the 11 reinforcing base plates 21 has a corresponding reinforcing tab 211 on its top and bottom. The 11 reinforcing base plates 21 are folded together end to end to form a rectangular reinforcing block 2170. After the reinforcing base plates 21 are arranged, the corresponding reinforcing tabs 211 are aligned. The aligned reinforcing tabs 211 are then pressed into the inner cavity of the reinforcing block 2170. Depending on the size and thickness requirements of the reinforcing block 2170, different numbers of reinforcing base plates 21 and reinforcing tabs 211 can be selected. The reinforcing tabs 211 on the reinforcing block 2170 improve the strength of the reinforcing block 2170 and prevent the reinforcing block 2170 from loosening.

[0049] like Figure 2 , 6As shown in Figure 9, the inner lining end plate 2200 includes a bottom folding block 2210, two side folding blocks 2220 and two upper folding blocks 2230. The two upper folding blocks 2230 abut against each other, and the two side folding blocks 2220 abut against each other. The side folding blocks 2220 are located below the corresponding upper folding blocks 2230. The bottom folding block 2210 covers the outside of the two side folding blocks 2220. The bottom of the bottom folding block 2210 abuts against the bottom surface of the inner cavity of the housing 1000, and the upper end of the bottom folding block 2210 abuts against the base of the display 4.

[0050] like Figure 6 , 9 As shown, the inner lining end plate 2200 is formed by folding the folded end plate 3. The folded end plate 3 includes a connecting outer plate 31, a connecting bottom plate 32, two connecting side plates 33, and two connecting upper plates 34. The upper parts of the opposite sides of the connecting outer plate 31 are respectively connected to the connecting upper plates 34. The lower part of the two connecting upper plates 34 is respectively provided with connecting side plates 33 connected to the connecting outer plate 31. The lower side of the connecting outer plate 31 is connected to the connecting bottom plate 32. The connecting side plates 33 are folded to form a side folding block 2220, the connecting bottom plate 32 is folded to form a bottom folding block 2210, and the connecting upper plates 34 are folded to form an upper folding block 2230.

Bottom 323 and fourth connecting bottom 324 are folded vertically toward connecting outer plate 31 in sequence to form a rectangular bottom folding block 2210. At this time, the fourth connecting bottom 324 is inserted between connecting outer plate 31 and fourth connecting side 334. Connecting upper plate 34 includes a first connecting upper part 341, a second connecting upper part 342, a third connecting upper part 343, a fourth connecting upper part 344 and a fifth connecting upper part 345 that are connected to connecting outer plate 31 in sequence. The fifth connecting upper part 345, the fourth connecting upper part 344, the third connecting upper part 343, the second connecting upper part 342 and the first connecting upper part 341 are folded vertically toward connecting outer plate 31 in sequence to form a rectangular upper folding block 2230. At this time, the fourth connecting upper part 344 abuts against connecting outer plate 31.

[0052] The connecting outer plate 31 is provided with two first latches 311, and the two fourth connecting upper parts 344 are respectively provided with second latches 3441 corresponding to the first latches 311. The two third connecting upper parts 343 are respectively provided with slots 3421 that engage with the corresponding first latches 311 and second latches 3441. After the upper folding block 2230 is formed, the first latches 311 are aligned with the corresponding second latches 3441, and the aligned first latches 311 and second latches 3441 are inserted into the corresponding slots 3421. This structure improves the firmness of the connection between the upper folding block 2230 and the connecting outer plate 31.

[0053] In this embodiment, both the box body 1000 and the inner packaging liner 2000 are made of corrugated cardboard. Corrugated cardboard provides good cushioning and is easy to cut and fold.
