Two sets of tension adjusting assemblies 100 and two sets of connecting assemblies 200 are respectively and evenly located on the tops of the two upper swing covers at the top of the box body of the corrugated cardboard box 4.

[0028] Usage method of an elastic zipper type corrugated cardboard box sealing device with adjustable tightness:

[0029] Step 1: Place one ends of the cloth belt outside the zipper 3 and the elastic cloth 11 on the two L surfaces of the convex block 21 respectively. Then place the second pressing plate 2 on the top of the convex block 21, and embed the third fixing cone 26 and the second fixing cone 24 in the tops of the cloth belt and the elastic cloth 11 respectively. At the same time, penetrate the third cone head column 25 through the cloth belt and insert it into the third positioning hole of the convex block 21, penetrate the second cone head column 23 through the elastic cloth 11 and insert it into the second positioning hole. Then use the second cross bolt 22 to penetrate the second counterbore of the second pressing plate 2 and be screwed with the first threaded hole of the convex block 21 to fix the second pressing plate 2 on the top of the convex block 21. At this time, the cloth belt outside the zipper 3 is positioned and fixed between the second pressing plate 2 and the convex block 21 through the third fixing cone 26 and the third cone head column 25. Similarly, one end of the elastic cloth 11 is stabilized between the second pressing plate 2 and the convex block 21 through the second cone head column 23 and the second fixing cone 24.

[0030] Step 2: Place one end of the elastic cloth 11 away from the convex block 21 and the second pressing plate 2 on the L surface of the L-shaped slider 13. Then, place the first pressing plate 14 on the L-shaped slider 13, embed the first fixing cone 16 on the top of the elastic cloth 11, insert the first cone head column 15 through the elastic cloth 11 and plug it into the first positioning hole of the L-shaped slider 13. Then, insert the L-shaped slider 13 and the first pressing plate 14 into the sliding groove of the storage box 1. When the first through hole on the first pressing plate 14 is aligned with the first counterbore on the corrugated cardboard box 4 of the storage box 1, pass the first cross bolt 12 through the first counterbore and the first through hole and thread it into the first threaded hole on the L-shaped slider 13 to fix the first pressing plate 14 on the top of the L-shaped slider 13, thereby fixing the elastic cloth 11 between the first pressing plate 14 and the L-shaped slider 13. At the same time, fix the L-shaped slider 13 and the first pressing plate 14 in the sliding groove of the storage box 1. Then, stick and fix the storage box 1 on the top of the upper swing cover on the top of the corrugated cardboard box 4 of the corrugated cardboard box 4 with the rear net double-sided tape 17 to complete the installation of the device.

[0031] Step 3: After opening the zipper 3 and dividing it into two parts, the two groups of upper swing covers on the top of the corrugated cardboard box 4 can be turned upwards to open. At this time, items can be loaded into the corrugated cardboard box 4. Then, when closing the two groups of upper swing covers with the top of the corrugated cardboard box 4, when the items in the corrugated cardboard box 4 are too many and the upper swing cover cannot fit with the box body, by pulling the elastic cloth 11 inwards, the elastic property of the elastic cloth 11 can be used to fit the zipper 3 divided into two parts, and the two parts are combined into one by zipping. At this time, the elastic cloth 11 drives the zipper 3 to press down the two groups of upper swing covers with its own resilience, so that the upper swing cover can be stably above the box body of the corrugated cardboard box 4, thus realizing the sealing of the upper swing cover and the box body. And after unscrewing the first cross bolt 12, the L-shaped slider 13 and the first pressing plate 14 can be slid in the sliding groove of the storage box 1. Then, pass the first cross bolt 12 through the first counterbores opened at different positions on the storage box 1 and connect it with the first pressing plate 14 and the L-shaped slider 13 to fix the positions of the L-shaped slider 13 and the first pressing plate 14, which can adjust the tightness of the elastic cloth 11, so as to achieve the effect of flexibly adjusting the tightness of the sealing.

[0032] Step 4: Since the storage box 1 is adhered to the upper flap of the corrugated cardboard box 4 by the reticulated double-sided tape 17, the storage box 1 can be directly torn off from the upper flap. Then, after separating the reticulated double-sided tape 17 from the storage box 1, the storage box 1 can be adhered to a new corrugated cardboard box 4 using a new reticulated double-sided tape 17. And by unscrewing the first cross bolt 12, the first pressing plate 14 and the L-shaped slider 13 can be taken out from the chute of the storage box 1. Then, moving the first pressing plate 14 upward to separate it from the elastic cloth 11 can complete the disassembly of the four components: the storage box 1, the L-shaped slider 13, the first pressing plate 14, and the elastic cloth 11. Similarly, after unscrewing the second cross bolt 22, the second pressing plate 2 can be moved upward to separate it from the elastic cloth 11 and the cloth tape of the zipper 3, thereby completing the disassembly of the four components: the second pressing plate 2, the convex block 21, the elastic cloth 11, and the zipper 3. By enabling the rapid disassembly and assembly of components, when a certain component is damaged, it can be quickly replaced, so that the remaining components can be recycled, thus avoiding unnecessary waste.
