Packaging cartons have become an indispensable part of modern logistics, and they are responsible for containing and protecting the transported items. For some large or more valuable items, the packaging cartons must also have sufficient compressive strength to prevent the stacking of goods during transportation from causing the packaging cartons below to collapse and affect the safety of the items inside.

[0003] As disclosed in the publication number: CN212333252U, a pressure-resistant packaging carton includes a box body with an opening at the top, characterized in that a top cover is detachably provided on the top of the box body, a base is detachably provided on the bottom of the box body, a plurality of support members are inserted into the four sides of the box body, a reinforcement assembly is provided on the bottom of the top cover, a shock-absorbing assembly is provided in the base, the top cover includes a top surface and side covers provided on four sides of the top surface, the top surface is provided at the top opening of the box body, and the side covers match the four sides of the box body; the shock-absorbing assembly includes a buffer plate, a buffer member and an elastic member, the buffer member is provided above the buffer plate, the elastic member is provided below the buffer plate and corresponds to the buffer member, and the elastic member is connected to the base. The utility model has a stable structure, good pressure resistance and shock absorption effect, and can effectively protect items from vibration damage.

[0004] When using common pressure-resistant packaging cartons, although the support components can be directly inserted into the four sides and corners of the carton body to effectively improve the load-bearing and pressure-resistant capacity of the box body, it is inconvenient to store the support components and occupies a large space. In addition, it is difficult to put items into or take items out of the packaging carton. Generally, items are stored manually, which is very inconvenient and can easily cause the items to collide with the packaging carton and be damaged. Utility Model Content

When in use, the limiting rod can be inserted into the limiting hole to limit the position of the square plate.

[0009] Preferably, in order to prevent the support plate from squeezing the articles, a buffer airbag is fixedly installed at the lower end of the support plate. When in use, the buffer airbag is used to buffer the impact force on the articles caused by the downward movement of the support plate to prevent damage to the articles.

[0010] Preferably, in order to facilitate the installation and disassembly of the support plate, a guide hole is opened at the upper end of the support rod, a guide rod is inserted into the guide hole, and the guide rod is fixedly connected to the support plate. When in use, the guide rod can move in the guide hole to play a guiding and limiting role to prevent the support plate from shifting in position during use.

[0011] Preferably, in order to smoothly move the U-shaped plate, the storage assembly includes a U-shaped plate, one end of the U-shaped plate is inserted into the connecting plate, and a connecting block is fixedly installed between the U-shaped plates.

DETAILED DESCRIPTION

[0021] The utility model is further described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figure 1-Figure 5As shown, the present embodiment provides a pressure-resistant packaging carton, comprising a box body 1 with an opening at the upper end, a box cover 2 inserted at the upper end of the box body 1, support rods 3 inserted inside the four side walls of the box body 1, connecting plates 4 fixedly installed between the support rods 3, support components 5 inserted at the upper ends of the support rods 3, and storage components 6 for storing and retrieving articles installed between the connecting plates 4. When in use, first open the box cover 2, manually place the articles on the storage components 6, and then transport the articles to the inside of the box body 1 through the storage components 6. After placement, unfold the support components 5, and then insert the support components 5 into the support rods 3 to enhance the pressure resistance of the box body 1. When squeezed by the packaging carton above, the support components 5 buffer the impact force to prevent damage to the articles inside the box body 1. When it is necessary to take out the articles, they can be taken out through the storage components 6.

[0023] like Figure 4 and Figure 5 As shown, the support assembly 5 includes symmetrically arranged support plates 501, square plates 502 are inserted between the support plates 501, and the square plates 502 are hinged, one end of the square plate 502 is provided with a limiting hole 503 in a linear array, one end of the support plate 501 is inserted with a limiting rod 504, one end of the limiting rod 504 extends into the limiting hole 503, a buffer airbag 505 is fixedly installed at the lower end of the support plate 501, a guide hole is provided at the upper end of the support rod 3, a guide rod 506 is inserted into the guide hole, and the guide rod 506 is fixedly connected to the support plate 501. When in use, the support plate 501 is first moved to both sides. The support plate 501 and the square plate 502 slide inside the support plate 501, and then the limiting rod 504 is inserted into the limiting hole 503 to fix the support plate 501. Then the support plate 501 is rotated, the guide rod 506 is aligned with the guide hole, and then the guide rod 506 is inserted into the guide hole, and the support plate 501 is connected to the support rod 3 to protect the items. When the goods above squeeze the items, the support plate 501 and the support rod 3 disperse their gravity. When the gravity is too large, the support plate 501 will bend to squeeze the items, and the cushioning airbag 505 will cushion the squeezing force to ensure that the items will not be damaged.

[0024] like Figure 5As shown, the storage component 6 includes a U-shaped plate 601, one end of the U-shaped plate 601 is inserted into the connecting plate 4, a connecting block 602 is fixedly installed between the U-shaped plates 601, the connecting block 602 and one end of the U-shaped plate 601 are in contact with the inner bottom end of the box body 1, and a handle 603 for moving the U-shaped plate 601 is fixedly installed at one end of the U-shaped plate 601. When in use, the handle 603 is manually moved upwards to drive the U-shaped plate 601 and the connecting block 602 to move upwards, and then the items to be stored are placed on the U-shaped plate 601 and the connecting block 602, and then the handle 603 is manually moved downwards to place the items inside the box body 1 for storage. When the items need to be taken out, the handle 603 is manually moved upwards to take out the items.

[0025] When the utility model is in use, first open the box cover 2, then manually move the handle 603 upwards to drive the U-shaped plate 601 to move upwards, then put the items to be stored on the U-shaped plate 601 and the connecting block 602, and then manually reset the handle 603, and the items are moved to the inside of the box body 1 for storage. When it is necessary to take out the items, manually move the handle 603 upwards to take out the items, which is convenient and quick, and it is not easy for the items to tilt and collide with the packaging carton to be damaged. After placing the items, manually move the support plate 501 to both sides, and then fix the support plate 501 with the limit rod 504, and then move the support plate 501 to both sides. Move the support plate 501 and insert the guide rod 506 into the guide hole to connect the support plate 501 to protect the items. When the goods above are heavy and squeeze the items inside the box 1, the support plate 501 and the support rod 3 will support and protect the box 1 to increase the load-bearing and pressure-resistant capacity of the box 1. When the gravity is too large, the buffer airbag 505 will buffer the excessive gravity to ensure that the items will not be damaged. After use, remove the limit rod 504, store the square plate 502 into the support plate 501, and then rotate the support plate 501 inward for storage. It is convenient to store and saves space.
