Description

Technical Field

[0001] This utility model relates to the field of packaging carton technology, specifically to an environmentally friendly packaging carton with pressure resistance. Background Technology

[0002] Packaging boxes are very common and important items in daily life, and are widely used in many fields such as logistics and transportation, warehousing, moving, e-commerce delivery, and product packaging. The most common packaging box material is corrugated cardboard, which is environmentally friendly, practical and economical.

[0003] A search revealed a Chinese patent (CN222876728U) disclosing an environmentally friendly packaging carton with pressure resistance. The carton includes a paper base plate with a magnetic sleeve adhered to its lower end. First paper baffles are located on both sides of the base plate, and second paper baffles are located on the other two sides. The base plate enables the second paper baffles to move. The first and second paper baffles facilitate disassembly and folding, increasing the device's practicality. A support sleeve secures the pressure-resistant frame, and the pressure-resistant frame and connecting frame enhance the carton's pressure resistance, further improving usability. A carton lid ensures tight contact with the magnetic blocks, and the magnetic blocks and sleeve facilitate orderly stacking of the cartons, further enhancing the device's usability.

[0004] However, in actual use, the above-mentioned patents mainly rely on the compression frame to achieve compression resistance. During transportation, the independent compression frame is easily shaken and detached, losing its protective function. In addition, there is no protective structure on the outside of the carton, which can only provide local compression resistance to the top and four corners of the carton. The overall compression resistance is weak. Therefore, we propose an environmentally friendly packaging carton with compression resistance function. Utility Model Content

[0005] The technical problem to be solved by this application is that the above-mentioned patent mainly relies on the compression frame to achieve the compression resistance. During transportation, the independent compression frame is easily shaken and detached, losing its protective function. In addition, no protective structure is set on the outside of the carton, which can only provide local compression resistance to the top and four corners of the carton, and the overall compression resistance is weak.

[0006] To address the aforementioned technical problems, this application provides an environmentally friendly packaging carton with compression resistance, comprising a base plate, with L-shaped support frames glued to the four corners of the top of the base plate, a top plate on the top of the support frames, the top plate and the support frames being rotatably engaged by a limiting structure, locking blocks installed at the four corners of the bottom of the base plate, and side plates inserted between adjacent support frames, with a support plate of a continuous triangular structure glued to the outer side of the side plate.

[0007] In some embodiments, the limiting structure includes a rotating rod that passes through the four corners of the top of the top plate, a rotating plate that extends into the outer side of the bottom of the top plate, a limiting block that is installed on the outer side of the rotating plate, and a limiting groove that is adapted to the size of the limiting block that is provided on the inner side of the support frame.

[0008] In some embodiments, the limiting structure further includes a circular plate installed at the top end of the rotating rod extending from the bottom of the top plate, and the top of the circular plate has a cross-shaped slot adapted to the size of the locking block.

[0009] In some embodiments, the limiting structure further includes a movable plate bonded to one side of the inside of the support frame. The top of the movable plate has two baffles arranged in a mirror shape, and a connecting plate is connected to the outer side of the two baffles. The bottom baffle is bonded to the movable plate. The gap between the two baffles is adapted to the size of the rotating rod and the rotating plate. The baffles and the rotating plate are both semi-circular rings. The connecting plate is U-shaped and does not contact the limiting block.

[0010] In some embodiments, the movable plate has a crease at the top near the adhesive joint, and the distance between the movable plate and the top of the support frame is adapted to the space inside the baffle and the support frame.

[0011] In some embodiments, the side plate has L-shaped inserts at both ends with the outer right angle being inclined, and the support frame has slots at both ends that are adapted to the size of the inserts.

[0012] This utility model has at least the following beneficial effects:

[0013] 1. Continuous triangular support plates were added to the outside of the side panels to distribute the pressure on the outside of the carton and improve its compressive strength. During stacking, the support plates on the outside of adjacent cartons can interlock to fix adjacent cartons and improve the stability of the cartons.

[0014] 2. The top plate and the support frame are engaged by a limiting structure, which is more stable than magnetic fixation and is less likely to detach during transportation.

[0015] 3. By setting up a locking block and a limiting structure, vertical stacking is fixed. Compared with magnetic materials, the whole structure is made of paper, which is conducive to environmental protection and recycling. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1: Please refer to Figures 1-6 This utility model provides a technical solution: an environmentally friendly packaging carton with pressure resistance, including a base plate 1, with L-shaped support frames 2 glued to the four corners of the top of the base plate 1, a top plate 4 provided on the top of the support frame 2, the top plate 4 and the support frame 2 being rotatably connected by a limiting structure 3, a locking block 5 installed at the four corners of the bottom of the base plate 1, and side plates 6 inserted between adjacent support frames 2, with a support plate 7 in the form of a continuous triangular structure glued to the outer side of the side plate 6.

[0028] The overall structure adopts a composite reinforcement structure with a kraft paper surface layer, vertical corrugated paper and a horizontal honeycomb core layer, and a hydrophobic film bottom layer, which improves the compressive strength and waterproof strength. The triangular support plate 7 disperses the pressure on the outside of the carton and improves the compressive strength. At the same time, the continuous triangular structure design allows the support plates 7 on the outside of adjacent cartons to interlock during stacking, further improving the fixation between adjacent cartons. Compared with the design of using magnetic sleeves and magnetic blocks, which can only fix vertically stacked cartons, this improves the stability of stacking.

[0029] The limiting structure 3 includes a rotating rod 301 that passes through the four corners of the top of the top plate 4. A rotating plate 302 is installed on the outer side of the bottom of the top plate 4 through the rotating rod 301. A limiting block 303 is installed on the outer side of the rotating plate 302. A limiting groove 201 that matches the size of the limiting block 303 is provided on the inner side of the support frame 2.

[0030] The limiting structure 3 also includes a rotating rod 301 extending out of the bottom of the top plate 4 and a circular plate 304 installed at the top. The top of the circular plate 304 has a cross-shaped slot 3041 that matches the size of the card block 5.

[0031] The top plate 4 and the support frame 2 are fixed by limiting block 303 and limiting groove 201. The operation is simple and only requires rotation to engage. The design of cross-shaped groove 3041 and locking block 5 can fix the cartons between vertical stacks without the need for additional materials to fix the vertical stacks, which reduces costs and is conducive to environmental protection and recycling.

[0032] Example 2: Based on Example 1, as follows Figure 6 and Figure 7 As shown, the limiting structure 3 also includes a movable plate 305 bonded to one side of the inside of the support frame 2. The top of the movable plate 305 is provided with two baffles 306 in a mirror shape. A connecting plate 307 is connected to the outside of the two baffles 306. The bottom baffle 306 is bonded to the movable plate 305. The gap between the two baffles 306 is adapted to the size of the rotating rod 301 and the rotating plate 302. Both the baffles 306 and the rotating plate 302 are semi-circular rings. The connecting plate 307 is U-shaped and does not contact the limiting block 303.

[0033] The baffle 306 is set to fix the rotating plate 302, so that when the limiting block 303 is fixed in the limiting groove 201, the rotating plate 302 is fixed in the baffle 306, thus fixing the movable plate 305. The movable plate 305 buffers the impact force of the goods in the carton, preventing the limiting block 303 from breaking under force. The connecting plate 307 supports the baffle 306, preventing the limiting block 303 from being blocked and affecting its rotation.

[0034] Example 3: Based on Example 2, such as Figure 6 and Figure 8As shown, the top of the movable plate 305 near the adhesive joint has a crease 3051, and the distance between the top of the movable plate 305 and the support frame 2 is adapted to the space inside the baffle 306 and the support frame 2.

[0035] By folding the movable plate 305 through crease 3051, the description of the movable plate 305 and the baffle 306 is increased so that when the movable plate 305 is folded, the baffle 306 is located on top of the support frame 2, reducing the space occupied by the movable plate 305 and preventing the movable plate 305 from blocking the loading and unloading of goods.

[0036] Example 4: Based on Example 3, such as Figure 9 As shown, the side plate 6 has L-shaped insert plates 601 with the outer right angle set at both ends, and the support frame 2 has slots 202 at both ends that are adapted to the size of the insert plates 601.

[0037] The sloping design facilitates the insertion of the insert plate 601 into the slot 202 of the side plate 6, limits the lateral movement of the side plate 6, and ensures the stability and firmness between the side plate 6 and the support frame 2.

[0038] Based on the above embodiments, the following is the complete working principle of the above embodiments: In use, four support frames 2 are glued to the top four corners of the base plate 1 so that the outer side of the support frame 2 is flush with the outer side of the base plate 1. Then, four side plates 6 are placed on top of the adjacent support frames 2. Insert plates 601 are inserted into the slots 202 of the support frames 2 to fix the four side plates 6 to the four support frames 2. Then, the movable plate 305 is folded through the crease 3051. Then, the goods are put in, and the movable plate 305 is rotated in the opposite direction so that it is on top of the goods. Then, the top plate 4 is placed on top of the support frames 2 and the side plates 6. The circular plate 304 is rotated. The circular plate 304 drives the rotating rod 301, the rotating plate 302 and the limiting block 303 to rotate. The rotating plate 302 rotates to the gap between the two baffles 306, and the limiting block 303 rotates into the limiting groove 201 of the support frame 2 to achieve the fixation between the top plate 4 and the support frame 2, thereby completing the packaging of the goods.
