Both ends of the first support strip 1 and the second support strip 4 are fixedly installed with pin blocks 3. The four sides of the reinforcing cardboard frame 6 are provided with pin holes 8. When the reinforcing cardboard frame 6 is installed inside the corrugated cardboard box body 9, the pin blocks 3 at the ends of the first support strip 1 and the second support strip 4 can be engaged with the four pin holes 8 inside the reinforcing cardboard frame 6 respectively. The first support strip 1 and the second support strip 4 are installed in a cross shape, so that the four inner corners of the reinforcing cardboard frame 6 are all at ninety degrees and will not change.

[0023] like Figure 3 As shown, curved cardboard 7 is fixedly installed on the outer surfaces of all four sides of the reinforced cardboard frame 6. Multiple curved cardboard 7 are installed on each side. When the reinforced cardboard frame 6 is not in use, it can be... Figure 4 Similarly, it is folded into a flat shape. When in use, it can be opened into a rectangular state, and then the reinforcing cardboard frame 6 is placed inside the corrugated cardboard box body 9 to reinforce the corrugated cardboard box body 9, making the corrugated cardboard box body 9 more stable during use. At this time, the curved cardboard 7 on the four sides of the reinforcing cardboard frame 6 is attached to the four sides of the inner wall of the corrugated cardboard box body 9. The gap between the corrugated cardboard box body 9 and the reinforcing cardboard frame 6 can cooperate with the curved cardboard 7 to form a buffer layer. The curved cardboard 7 can form folds, and the gaps between the folds can absorb external impact force, which can play a certain buffering role for the corrugated cardboard box body 9.

[0024] in,

[0025] Corrugated cardboard box body 9: This is the basic load-bearing structure of the device, used to hold items, and also provides installation space for components such as the reinforced cardboard frame 6. It is the main body that needs to be reinforced and have its performance improved.

[0026] Reinforcing cardboard frame 6: Set inside the corrugated cardboard box body 9, its main function is to reinforce the corrugated cardboard box body 9 and enhance the stability of its overall structure. It has pin holes 8 on its four sides for connecting with the first support strip 1 and the second support strip 4. The outer surfaces of the four sides are also fixedly installed with curved cardboard 7.

[0027] First support strip 1: Installed inside the reinforcing paper frame 6, it has a first slot 2 and pin blocks 3 fixedly installed at both ends. It is engaged with the second slot 5 of the second support strip 4 through the first slot 2, and connected with the pin holes 8 of the reinforcing paper frame 6 through the pin blocks 3, so as to support the reinforcing paper frame 6 and ensure the stability of the reinforcing paper frame 6 structure.

[0028] The second support strip 4 is used in conjunction with the first support strip 1. It has a second slot 5 and pin blocks 3 are fixedly installed at both ends. It is engaged with the first slot 2 of the first support strip 1 through the second slot 5, and then connected to the pin hole 8 of the reinforcing paper frame 6 through the pin block 3. Together with the first support strip 1, it forms a support for the reinforcing paper frame 6 and maintains its shape stability.

When the reinforcing cardboard frame 6 is placed inside the corrugated cardboard box 9, it fits against the inner wall of the corrugated cardboard box 9 and can form folds. The gaps between the folds can absorb external impact and play a buffering role. At the same time, it helps the reinforcing cardboard frame 6 to enhance the stability of the corrugated cardboard box 9.

[0031] Working principle:

[0032] The first step is to unfold the reinforcing cardboard frame 6 to make it rectangular. At this time, the curved cardboard 7 on the outer surfaces of the four sides of the reinforcing cardboard frame 6 will be in the corresponding positions as it is unfolded.

[0033] The second step is to assemble the first support strip 1 and the second support strip 4 by engaging the first slot 2 on the first support strip 1 with the second slot 5 on the second support strip 4, so that the two form a cross shape and are on the same plane.

[0034] The third step is to install the assembled first support strip 1 and second support strip 4 onto the reinforced paper frame 6, and to snap the pins 3 at both ends of them into the pin holes 8 on the four sides of the reinforced paper frame 6 respectively. The cross-shaped support structure ensures that the four inner corners of the reinforced paper frame 6 remain stable at ninety degrees.

[0035] The fourth step is to place the reinforced cardboard frame 6, with its supporting structure installed, inside the corrugated cardboard box 9, ensuring that the curved cardboard 7 on all four sides of the reinforced cardboard frame 6 fits snugly against the four sides of the inner wall of the corrugated cardboard box 9. The folds formed by the curved cardboard 7 and the gaps between them and the corrugated cardboard box 9 constitute a buffer layer that absorbs external impact. At the same time, the reinforced cardboard frame 6 strengthens the corrugated cardboard box 9, improving its overall stability.
