In terms of the folding and connecting methods of corrugated paperboards, they can be connected by gluing or snap-on design. Although the connection method using additional fixing processes such as gluing can reduce the design amount of corrugated paperboards, it requires additional processes for bonding. The snap-on design is usually achieved by only one or two plug-in plates and sockets, which cannot effectively guarantee the strength of the entire box and is prone to loosening the matching structure under the action of external forces.

[0015] From the above description, it can be seen that the beneficial effects of the utility model are: the front panel 2 and the back panel 4 are quickly connected by the clamping and fixing of the first clamping plate 21 of the front panel 2 and the second clamping plate 41 of the back panel 4; and then the first clamping plate 21 and the second clamping plate 41 are pressed by the fixing plate 31 of the side panel 3 to further fix the first clamping plate 21 and the second clamping plate 41 to prevent the two from detaching from each other; finally, the fixing plate 31 is fixed by the clamping of the fixing plate 31 with the front panel 2 and the back panel 4; this design can quickly fold the carton into shape, and at the same time, under the design of the clamping cooperation of the first clamping plate 21 and the second clamping plate 41, the pressing and fixing of the fixing plate 31 with the first clamping plate 21 and the second clamping plate 41, and the clamping and fixing of the fixing plate 31 with the front panel 2 and the back panel 4, the connection integrity of the cardboards of the box body is improved, and the strength of the box body is improved.

[0016] Working principle: when folding, the front panel 2 and the rear panel 4 are folded toward the bottom panel 1 to a state perpendicular to the bottom panel 1, and then the first clamping plate 21 of the front panel 2 and the second clamping plate 41 of the rear panel 4 are folded toward the bottom panel 1 to a state perpendicular to the front panel 2 and the rear panel 4. At this time, the first clamping plate 21 and the second clamping plate 41 are opposite to each other and are engaged through the first clamping groove 22 and the second clamping groove 42; then, the side panel 3 and the fixing plate 31 are folded toward the bottom panel 1 in turn to a state perpendicular to the bottom panel 1, and the fixing plate 31 presses the first clamping plate 21 and the second clamping plate 41 against the side panel 3 to fix it, and the two sides of the fixing plate 31 are engaged and fixed with the front panel 2 and the rear panel 4.

[0018] It can be seen from the above description that the triangular design of the first clamping slot 22 and the second clamping slot 42 allows the two to be quickly clamped together along the inclined surface of the triangle when they are docked.

[0019] Furthermore, the two sides of the fixing plate 31 are connected to the convex plates 32 , and the two sides of the front plate 2 and the rear plate 4 corresponding to the fixing plate 31 are provided with insertion holes 23 ; the convex plates 32 are plugged and matched with the insertion holes 23 .

[0020] As can be seen from the above description, the fixing plate 31 is fixed to the front plate 2 and the rear plate 4 by plugging the protruding plates 32 on both sides of the fixing plate 31 into the insertion holes 23 of the front plate 2 and the rear plate 4 .

[0021] Furthermore, it also includes a top plate 5 , the side of the rear plate 4 away from the bottom plate 1 is connected to the top plate 5 , the two sides of the top plate 5 are connected to the side cover plates 6 , and the side of the top plate 5 away from the rear plate 4 is connected to the front cover plate 7 .

[0022] From the above description, it can be seen that the folded top panel 5 covers the top of the box body. At the same time, the design of the side cover plate 6 and the front cover plate 7 on the top panel 5 enables them to be buckled with the folded front panel 2, rear panel 4, and side panel 3 structure and cover the docking gap, thereby improving the dustproof effect.

[0023] Furthermore, a front connecting plate 8 is connected between the front cover plate 7 and the top plate 5; a snap-on plate 61 is connected to the side of the side cover plate 6 away from the second clamping plate 41, and a snap-on ring 62 is provided on the snap-on plate 61 close to the front cover plate 7; a snap-on protrusion 71 is provided on the side of the front cover plate 7 away from the front connecting plate 8; the snap-on protrusion 71 is inserted into the snap-on ring 62; the snap-on plate 61 is folded between the front connecting plate 8 and the front cover plate 7.

[0024] From the above description, it can be known that in order to enable the front cover plate 7 and the side cover plate 6 to form an integrated snap-fit ​​structure on the upper edge of the box body formed by the folded bottom plate 1, the front plate 2, the side plate 3 and the rear plate 4, the side cover plate 6 and the front cover plate 7 are connected as one by setting the snap-fit ​​plate 61 and the snap-fit ​​ring 62 of the side cover plate 6 and the snap-fit ​​protrusion 71 of the front cover plate 7, so that the side cover plate 6 and the front cover plate 7 can be connected as one, so as to better cooperate with the top plate 5 to be snap-fitted on the top of the box body.
