[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Reference Figure 1-Figure 3 The top of the box 1 is fixedly connected to the front of the box 1 and the two partitions 13 are provided with a through hole 2. The through hole 2 is provided to achieve the effect of sealing the top of the box 1. The top front of the box 1 is fixedly connected to a paper cover 1 3. The left and right sides of the top of the box 1 are fixedly connected to a paper cover 2 4. The top rear side of the box 1 is fixedly connected to a paper cover 3 5. The top of the paper cover 3 5 is fixedly connected to a paper cover 4 6. A notch 7 is provided in the middle of the paper cover 4 6. The tops of the articles in the paper cover 2 4 are folded in sequence, and then the paper cover 1 3 is folded. Finally, the paper cover 3 5 and the paper cover 4 6 are folded so that the paper cover 4 6 fits the front side of the box 1, and then the notch 7 of the paper cover 4 6 is inserted into the through hole 2, so as to achieve self-locking fixation of the top of the box 1. Four triangular supports 8 are fixedly connected to the upper and lower sides of the interior of the box 1. The triangular supports 8 support the upper and lower four corners of the box 1, effectively preventing the four corners of the carton from being deformed after being hit.

[0033] refer to Figure 3 、 Figure 4 The adjacent sides of the two triangular supports 8 are fixedly connected with a sleeve 9, and the outer side of the block 11 is slidably connected to the inner wall of the sleeve 9. When the triangular support 8 is impacted, the sleeve 9 will be driven to slide on the outside of the block 11. The top of the inner side of the sleeve 9 is fixedly connected with a rubber pad 10, and the bottom end of the rubber pad 10 is fixedly connected with the block 11. The adjacent sides of the upper and lower blocks 11 are fixedly connected with support rods 12. When the carton falls and the top is impacted, the upper and lower sides of the triangular support 8 will be impacted to squeeze the sleeve 9. After being squeezed, the sleeve 9 will slide first and then the outer side of the block 11 will fit with the upper and lower sides of the support rod 12.

[0034] Then, the rubber pad 10 inside the sleeve 9 is squeezed and deformed. After the deformation, the rubber pad 10 will slide the sleeve 9 and the triangular support 8 back to their original position due to its own elastic force. The outside of the notch 7 engages with the inner wall of the through hole 2. The notch 7 is inserted into the through hole 2 to seal the top of the box 1. Compared with the above documents, the sealing structure and support structure are added to the original structure, which increases the stability of the overall structure of the carton and prolongs the service life of the carton.

[0035] refer to Figure 5 A groove 14 is provided inside the partition 13, and a through slot 15 is fixedly connected to the top end of the rear side of the partition 13. The inner wall of the through slot 15 is slidably connected to a limiting component. The groove 14 is provided to provide space for the limiting component to move. The user can pull the limiting component through the through slot 15. The limiting component includes a card rod 16, an anti-slip block 17, a spring 18, a pull rod 19, an extension plate 20 and a limiting slot 21. The outside of the card rod 16 is slidably connected to the inner wall of the through slot 15, the middle part of the anti-slip block 17 is fixedly connected to the middle part of the card rod 16, and the bottom end of the spring 18 is fixedly connected to the top of the anti-slip block 17.

[0036] The bottom end of the pull rod 19 is fixedly connected to the top end of the card rod 16. The user detents the pull rod 19 through the through slot 15, thereby pulling the pull rod 19 to drive the anti-slip block 17 on the card rod 16 to squeeze the spring 18, so that the card rod 16 can be extended and retracted from the inner wall of the through slot 15. The outer part of the extension plate 20 is slidably connected to the inner wall of the groove 14. The limiting groove 21 is opened at the top end of the extension plate 20. After the card rod 16 extends out of the through slot 15, the extension plate 20 can be pulled to slide in the groove 14.

[0037] The bottom end of the spring 18 is fixedly connected to the top rear side of the groove 14, and the right side of the card rod 16 is slidably connected to the inner wall of the groove 14. The spring 18 connects the groove 14 and the anti-slip block 17 to limit the card rod 16 and prevent the card rod 16 from falling out of the groove 14. The bottom end of the card rod 16 is engaged with the bottom end of the limiting groove 21, and the bottom curved surface of the card rod 16 and the wavy groove at the bottom of the limiting groove 21 are engaged and fixed to the limiting groove 21. The right side of the anti-slip block 17 is slidably connected to the inner wall of the groove 14, and the left side of the anti-slip block 17 is slidably connected to the inner wall of the limiting groove 21. This design is to increase the stability of the extension plate 20 during the sliding process and prevent the extension plate 20 from shaking during the sliding process. The front side of the partition 13 and the rear side of the extension plate 20 are engaged with the inner wall of the box 1, and the partition 13 and the extension plate 20 are engaged in the box 1 to isolate and fix the items placed therein.

[0038] Working principle: When you need to use a cardboard box to store items, you can first place the items in the box 1, and then, according to the size of the items, pull the pull rod 19 on the partition 13 to drive the card rod 16 and the anti-slip block 17 to squeeze the top of the inner wall of the groove 14, and retract to the top position of the inner wall of the groove 14, so that the card rod 16 is disengaged from the limit groove 21 of the extension plate 20, so that the extension plate 20 can be pulled to slide in the groove 14 of the partition 13, so that the partition 13 and the extension plate 20 are loosened from the engagement with the inner wall of the box 1, and the position of the partition 13 and the groove 14 can be adjusted, so that the placed items can be reasonably isolated, clamped and stored.

[0039] After the items are placed, fold the tops of the items on paper cover 2 (4) in turn, then fold paper cover 1 (3), and finally fold paper cover 3 (5) and paper cover 4 (6), so that paper cover 4 (6) fits the front side of box 1, and then insert the notch 7 of paper cover 4 (6) into the through hole 2 to achieve sealing and fixation of the top of box 1 and seal the items inside box 1.

[0040] When the carton falls or the four corners of the outside are impacted, the force of the four corners will be absorbed and resisted by the triangular support 8, and the impact of falling and the top will impact the upper and lower sides of the triangular support 8 to squeeze the sleeve 9. After being squeezed, the sleeve 9 will first slide and then fit the outside of the block 11 with the upper and lower sides of the support rod 12, and then squeeze the rubber pad 10 in the sleeve 9 to deform. After the rubber pad 10 is deformed, its own elastic force will drive the sleeve 9 and the triangular support 8 to slide and reset, thereby absorbing the impact force, protecting the outside of the carton, and further reinforcing the carton.

[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
