[0001] This utility model relates to the field of express delivery cardboard boxes, and in particular to a foldable, moisture-proof, reinforced express delivery cardboard box. Background Technology

[0002] Express delivery refers to the service of quickly collecting, transporting, and delivering individually packaged items. With the booming development of e-commerce, the express delivery industry has experienced explosive growth. Express delivery integrates functions such as information transmission, item delivery, and fund flow, forming an efficient logistics model. During the delivery process via express delivery, some items need to be stored inside the cardboard box.

[0003] In related technologies, some express delivery items are stored using cardboard boxes. Cardboard boxes are the most commonly used containers in the express delivery industry. They are made primarily of corrugated cardboard and are characterized by their light weight, low cost, and easy recyclability. Their structure typically consists of a face paper, a liner paper, and a core paper. By combining different flute types, they can meet the packaging needs of items of different weights. Cardboard boxes can effectively cushion impacts and compressions during transportation, protecting items from damage.

[0004] However, after the cardboard box is sealed, the middle part may be relatively weak. If an item directly hits the middle of the box, it may cause the middle of the box to be dented and damaged.

[0005] Therefore, it is necessary to provide a foldable, moisture-proof, reinforced express delivery box to solve the above problems. Utility Model Content

[0006] To address the technical problem that direct collisions with the cardboard box may cause dents and damage to the center of the box, this utility model provides a foldable, moisture-proof, reinforced express cardboard box.

[0007] This utility model provides a foldable, moisture-proof, reinforced express delivery carton, comprising: an express delivery carton body, an internal U-shaped reinforcing bracket, double-sided adhesive tape pasted on the outer wall of the U-shaped reinforcing bracket, the side of the double-sided adhesive tape away from the U-shaped reinforcing bracket being bonded to the inner wall of the express delivery carton body, a reinforcing strip, and a support plate. The reinforcing strip is movably disposed at one end of the U-shaped reinforcing bracket, and the support plate is fixedly disposed on the inner wall of the U-shaped reinforcing bracket on the side away from the reinforcing strip to support the bent reinforcing strip. The auxiliary reinforcing plate is rotatably disposed at the bottom of the inner wall of the U-shaped reinforcing bracket.

[0008] Preferably, the express carton body includes an outer paper layer, a waterproof membrane is fixedly connected to the inner wall of the outer paper layer, a paper honeycomb core is fixedly connected to the inner wall of the waterproof membrane, an inner paper layer is fixedly connected to the inner wall of the paper honeycomb core, and the outer wall of the double-sided adhesive is bonded to the inner wall of the inner paper layer.

[0009] Preferably, the U-shaped reinforcing bracket includes a U-shaped plate, the outer wall of the U-shaped plate is bonded to the inner wall of the double-sided adhesive, one end of the U-shaped plate is fixedly connected to one end of the reinforcing strip, one side of the inner wall of the U-shaped plate is fixedly connected to one side of the support plate, and a connecting groove is provided at the bottom of the inner wall of the U-shaped plate.

[0010] Preferably, a mating block is fixedly connected to the side wall of the end of the reinforcing strip away from the U-shaped plate, and a limiting groove is provided on the support plate, the inner diameter of the limiting groove matching the outer diameter of the mating block.

[0011] Preferably, the auxiliary reinforcing plate includes a rectangular plate, and a connecting block is fixedly connected to the lower surface of the rectangular plate. The connecting block is located inside the connecting groove, and the two are rotatably connected.

[0012] Preferably, adhesive sheets are fixedly connected to the lower surfaces of both ends of the rectangular plate, and the lower surfaces of the adhesive sheets are bonded to the bottom of the inner wall of the inner paper layer.

[0013] Compared with related technologies, the foldable, moisture-proof, reinforced express delivery carton provided by this utility model has the following beneficial effects:

[0014] 1. This foldable, moisture-proof, reinforced express carton can improve the strength of the middle part of the express carton body: the inner wall of the express carton body is tightly bonded with a U-shaped reinforcing bracket by double-sided adhesive. The U-shaped reinforcing bracket can restrict the installation position of the reinforcing strip and the support plate. After the reinforcing strip is bent, one end can be placed on the support plate, so that the U-shaped reinforcing bracket, the reinforcing strip and the support plate can form a rectangular support frame. The rectangular support frame can form a ring-shaped support structure in the middle of the express carton body, thereby improving the strength of the middle part of the express carton body and preventing the middle part of the express carton body from being dented and damaged due to direct collision of items with the middle part of the express carton body. The auxiliary reinforcing plate is rotated to form a cross with the U-shaped reinforcing bracket. The cross structure can enhance the stability between the bottom of the express carton body and the U-shaped reinforcing bracket, and at the same time, it can further enhance the overall deformation resistance of this application.

[0015] 2. This foldable, moisture-proof, reinforced express carton features an outer paper layer that works in conjunction with the inner paper layer to restrict the installation position of the waterproof membrane and paper honeycomb core. The paper honeycomb core enhances the strength of the express carton, while the waterproof membrane prevents external moisture from entering the carton and affecting the storage of items. The connecting block inserted into the limiting groove improves the stability of the connection between the reinforcing strip and the support plate.

[0016] 3. This foldable, moisture-proof, reinforced express carton features a U-shaped panel that restricts the installation position of the reinforcing strips and support plates. The connecting block and connecting groove further restrict the installation position of the rectangular panel on the U-shaped panel, while also facilitating rotation and adjustment. When the rectangular panel is rotated and adjusted to a cross-shaped position with the U-shaped panel, the adhesive sheet restricts the position between the rectangular panel and the inner paper layer, thereby improving the stability of the rectangular panel during use.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please refer to the following: Figures 1 to 5 A foldable, moisture-proof, reinforced express delivery carton includes: an express delivery carton body 1, an internal U-shaped reinforcing bracket 2, double-sided adhesive 3 pasted on the outer wall of the U-shaped reinforcing bracket 2, the side of the double-sided adhesive 3 away from the U-shaped reinforcing bracket 2 being bonded to the inner wall of the express delivery carton body 1, a reinforcing strip 4, and a support plate 5. The reinforcing strip 4 is movably disposed at one end of the U-shaped reinforcing bracket 2, and the support plate 5 is fixedly disposed on the inner wall of the U-shaped reinforcing bracket 2 on the side away from the reinforcing strip 4 to support the bent reinforcing strip 4. An auxiliary reinforcing plate 6 is rotatably disposed at the bottom of the inner wall of the U-shaped reinforcing bracket 2.

[0025] In the specific implementation process, the foldable moisture-proof reinforced express carton is equipped with a foldable carton body 1. The interior of the express carton body 1 is used to store items that need to be delivered by express. A U-shaped reinforcing bracket 2 is tightly glued to the inner wall of the express carton body 1 with double-sided adhesive 3. A reinforcing strip 4 is installed at one end of the U-shaped reinforcing bracket 2, and a support plate 5 is installed on the other side of the inner wall. After the personnel place the items inside the express carton body 1, the reinforcing strip 4 can be bent so that the end of the reinforcing strip 4 away from the U-shaped reinforcing bracket 2 rests on the support plate 5. Thus, the U-shaped reinforcing bracket 2, the reinforcing strip 4, and the support plate 5 can form a rectangular support frame. After the opening on the box body 1 is closed, a ring-shaped support structure can be formed in the middle of the express carton body 1 through the rectangular support frame, thereby improving the strength of the middle part of the express carton body 1 and preventing the middle part of the express carton body 1 from being dented and damaged due to direct collision of items. Furthermore, an auxiliary reinforcement plate 6 is rotatably installed on the bottom of the inner wall of the U-shaped reinforcement bracket 2. When in use, the operator can rotate the auxiliary reinforcement plate 6 to form a cross with the U-shaped reinforcement bracket 2. The cross structure can enhance the stability between the bottom of the express carton body 1 and the U-shaped reinforcement bracket 2, and at the same time, it can further enhance the overall anti-deformation ability of this application.

[0026] See Figure 1 , Figure 2 and Figure 3 As shown, the express carton body 1 includes an outer paper layer 101, a waterproof membrane 102 is fixedly connected to the inner wall of the outer paper layer 101, a paper honeycomb core 103 is fixedly connected to the inner wall of the waterproof membrane 102, an inner paper layer 104 is fixedly connected to the inner wall of the paper honeycomb core 103, and the outer wall of the double-sided adhesive 3 is bonded to the inner wall of the inner paper layer 104.

[0027] In the specific implementation process, the outer paper layer 101 and the inner paper layer 104 are set together to restrict the installation position of the waterproof membrane 102 and the paper honeycomb core 103. The paper honeycomb core 103 can play a supporting and buffering role, improving the strength of the express carton body 1. The waterproof membrane 102 can improve the waterproof and moisture-proof effect of the express carton body 1, so as to prevent external moisture from entering the express carton body 1 and affecting the storage of items.

[0028] Specifically, it should be noted that both the outer paper layer 101 and the inner paper layer 104 can be made of kraft paper or other high-strength paper.

[0029] See Figure 2 , Figure 3 and Figure 4As shown, the U-shaped reinforcing bracket 2 includes a U-shaped plate 201. The outer wall of the U-shaped plate 201 is bonded to the inner wall of the double-sided adhesive 3. One end of the U-shaped plate 201 is fixedly connected to one end of the reinforcing strip 4. One side of the inner wall of the U-shaped plate 201 is fixedly connected to one side of the support plate 5. A connecting groove 202 is provided at the bottom of the inner wall of the U-shaped plate 201.

[0030] In the specific implementation process, the U-shaped plate 201 can restrict the installation position of the reinforcing strip 4 and the support plate 5, and the opening of the connecting groove 202 can restrict the installation position between the auxiliary reinforcing plate 6 and the U-shaped plate 201.

[0031] See Figure 1 , Figure 2 and Figure 4 As shown, a mating block 7 is fixedly connected to the side wall of the reinforcing strip 4 away from the U-shaped plate 201. A limiting groove 8 is opened on the support plate 5, and the inner diameter of the limiting groove 8 matches the outer diameter of the mating block 7.

[0032] In the specific implementation process, when the reinforcing strip 4 is bent and placed on the support plate 5, the set docking block 7 can be inserted into the limiting groove 8, thereby improving the stability of the connection between the reinforcing strip 4 and the support plate 5.

[0033] See Figure 3 , Figure 4 and Figure 5 As shown, the auxiliary reinforcing plate 6 includes a rectangular plate 601, and a connecting block 602 is fixedly connected to the lower surface of the rectangular plate 601. The connecting block 602 is located inside the connecting groove 202, and the two are rotatably connected.

[0034] In the specific implementation process, by cooperating with the connecting block 602 and the connecting groove 202, the installation position of the rectangular plate 601 on the U-shaped plate 201 can be restricted, and it is also convenient for personnel to rotate and adjust the rectangular plate 601.

[0035] See Figure 2 and Figure 4 As shown, adhesive sheets 9 are fixedly connected to the lower surfaces of both ends of the rectangular plate 601, and the lower surfaces of the adhesive sheets 9 are bonded to the bottom of the inner wall of the inner paper layer 104.

[0036] In the specific implementation process, when the rectangular plate 601 is rotated and adjusted to be in a cross-shaped state with the U-shaped plate 201, the adhesive sheet 9 can restrict the position between the rectangular plate 601 and the inner paper layer 104, thereby improving the stability of the rectangular plate 601 during use.

[0037] The working principle of the foldable, moisture-proof, reinforced express delivery cardboard box provided by this utility model is as follows:

[0038] When using this foldable, moisture-proof, reinforced express carton, the carton body 1 consists of an outer paper layer 101, a waterproof membrane 102, a paper honeycomb core 103, and an inner paper layer 104. The waterproof membrane 102 provides moisture protection, and the paper honeycomb core 103 provides support and cushioning. First, rotate the auxiliary reinforcing plate 6 at the bottom of the inner wall of the U-shaped reinforcing bracket 2. This is achieved by rotating the auxiliary reinforcing plate 6 within the connecting groove 202 via the connecting block 602, so that the auxiliary reinforcing plate 6 and the U-shaped reinforcing bracket 2 form a cross shape. Then, use adhesive tape 9 to bond the auxiliary reinforcing plate 6 to the bottom of the inner paper layer 104, reinforcing the bottom of the carton against the auxiliary reinforcing plate 6 and the U-shaped reinforcing bracket 2. To ensure the stability and overall resistance to deformation of the U-shaped reinforcing bracket 2, the item is placed inside the foldable cardboard box 1. The reinforcing strip 4 at one end of the U-shaped reinforcing bracket 2 is bent so that the end of the reinforcing strip 4 away from the U-shaped reinforcing bracket 2 rests on the support plate 5. At this time, the connecting block 7 on the reinforcing strip 4 is inserted into the limiting groove 8 of the support plate 5, so that the U-shaped reinforcing bracket 2, the reinforcing strip 4 and the support plate 5 form a rectangular support frame, forming a ring support in the middle of the cardboard box 1 to prevent the middle of the cardboard box from being dented due to collision with the item. Finally, the opening of the cardboard box 1 is closed to complete the packaging.
