[0008] The partition assembly consists of a support plate and longitudinal and transverse plates vertically fixed on the support plate, and the longitudinal and transverse plates are cross-overlapped. A number of partition supports are evenly distributed in the vertical direction on the inner wall where the long side of the box side panel is located, and brackets corresponding to the partition supports are provided on the surface of the transverse and vertical plates. The partition supports consist of a support plate and a bending plate. A number of strip grooves are also provided on the inner wall where the long side of the box side panel is located. When the bending plate is buckled in the bracket, the support plate is horizontally unfolded; when the bending plate is inserted in the strip groove, the support plate is vertically folded.

[0009] In a further embodiment, a protruding piece is provided on the inner bottom surface of the bracket, and a straight slot hole matching the protruding piece is provided at the crest of the bent plate.

[0010] In a further embodiment, the support plate is tightly attached to the bottom of the second box bottom plate, and the four corners of the support plate are connected to the second box bottom plate by rivets.

[0011] In a further embodiment, a first through-slot is provided on the surface of the first box bottom plate for the longitudinal plates to pass through, and a second through-slot is provided on the surface of the second box bottom plate for the transverse plates to pass through.

[0012] In a further embodiment, a plurality of partitions parallel to the longitudinal plates are vertically inserted on the transverse and vertical plates, and slot two is provided on the surface of the transverse and vertical plates, and slot three matching with slot two is provided on the surface of the partitions.

[0013] In a further embodiment, the box cover adopts an L-shaped structure, and a slot 1 which matches the partition plate and the vertical plate is opened on the short side surface of the L-shaped structure.

[0014] In a further embodiment, a pressure strip is vertically connected to the top of the horizontal and vertical plates, and the pressure strip horizontally presses the bent portion of the box cover plate.

The partition support members 8 are composed of a support plate 81 and a bent plate 82. One side of the support plate 81 is fixed to the inner wall of the side panel 1 of the box, and the other side is connected to the bent plate 82. The bent plate 82 adopts an inverted V-shaped structure. When the bent plate 82 is buckled in the bracket 71, the support plate 81 is horizontally unfolded to facilitate the upper and lower separation of the space in the box. Furthermore, in order to prevent the partition support members 8 on both sides from interfering with each other, the bent plate 82 of the partition support member 8 on one side is located in the middle of one side of the support plate 81, and the bent plate 82 of the partition support member 8 on the other side is located on both sides of one side of the support plate 81 to prevent the bent plates 82 from overlapping when both sides are unfolded.

[0032] See also Figure 5 and Fig.10 In order to facilitate the adjustment of the size of the separated space, a plurality of grooves 11 are provided on the inner wall where the long side of the box side panel 1 is located. The grooves 11 are located at the lower edge of the connection point between the support plate 81 and the box side panel 1. When the bent plates 82 are fitted together and inserted into the grooves 11, the support plates 81 are vertically folded and buckled on the inner wall of the box side panel 1, which not only has a certain anti-collision and buffering effect, but also makes the size of the separated longitudinal space adjustable according to the actual size of the items. At the same time, a plurality of partitions 9 parallel to the longitudinal and vertical plates 6 are vertically inserted on the horizontal and vertical plates 7, and a slot 2 72 is provided on the surface of the horizontal and vertical plates 7, and a slot 3 91 matching the slot 2 72 is provided on the surface of the partition 9, so that when the partition 9 is inserted downward into the slot 2 72, the partition 9 crosses with the horizontal and vertical plates 7, which is convenient for adjusting the size of the horizontal space.

[0033] See also Figure 6-8 In order to improve the stability of the horizontal support of the support plate 81, a protruding piece 711 is provided on the inner bottom surface of the bracket 71, and a straight slot hole 821 matching the protruding piece 711 is opened at the crest of the bending plate 82, so that when the bending plate 82 is buckled in the bracket 71, the protruding piece 711 can pass through the straight slot hole 821, which has a certain limiting effect and prevents the bending plate 82 from slipping.

[0034] See also Figure 2-4In order to improve the firmness of the entire packaging box, a support plate 5 is arranged close to the bottom of the box bottom plate 4, and the four corners of the support plate 5 are connected to the box bottom plate 4 by rivets 51, so as to protect the bottom of the box body, prevent the bottom from being detached, and enhance the wear resistance of the bottom. A through groove 31 for the vertical plate 6 to pass through is provided on the surface of the box bottom plate 3, and a through groove 41 for the horizontal and vertical plates 7 to pass through is provided on the surface of the box bottom plate 4, which is convenient for assembling the partition assembly with the box bottom plate.

[0035] See also Figure 1 In order to facilitate the self-locking of the entire packaging box, the box cover 2 is set to adopt an L-shaped structure, and the short side surface of the L-shaped structure is provided with a slot 21 that matches the partition 9 and the vertical plate 6, so that when the box cover 2 is closed, the partition 9 and the vertical plate 6 are inserted into the slot 21, and at the same time, the top of the horizontal plate 7 is vertically connected with a pressure strip 73, and the pressure strip 73 horizontally presses the bent part of the box cover 2, so as to lock the box cover 2 and prevent it from bouncing open.
