[0002] Eco-friendly cardboard boxes are green packaging products made from renewable, recyclable, or biodegradable materials through low-carbon production processes. They aim to reduce resource consumption, minimize environmental pollution, and promote a circular economy. Combining the practicality and environmental benefits of traditional cardboard boxes, they have become an important direction for packaging upgrades in modern logistics, e-commerce, and various industries.

[0003] While the existing grid-like reinforcement structure has improved the overall stability of environmentally friendly cardboard boxes to some extent, its compressive strength is still significantly limited in actual use. In particular, the corners of the cardboard boxes are prone to deformation or even breakage when subjected to vertical pressure or stacking compression due to concentrated stress and weak structural support. As a result, the overall compressive strength is difficult to meet the requirements of high-strength packaging. Utility Model Content

[0004] The purpose of this utility model is to provide a pressure-resistant, reinforced, environmentally friendly cardboard box with a grid pattern, which aims to solve the problem that in the existing technology, the corners of cardboard boxes are prone to deformation or even damage when subjected to vertical pressure or stacking compression due to concentrated stress and weak structural support, resulting in the overall pressure resistance failing to meet the requirements of high-strength packaging.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pressure-resistant, reinforced, environmentally friendly cardboard box with a grid pattern, comprising a cardboard box body and a cover plate connected to the edge of the opening of the cardboard box body.

The inner wall of the cardboard box body is connected to a T-shaped limiting block, and the side surface of the first horizontal bar is provided with a limiting slot that is adapted to the limiting block.

[0009] As a preferred embodiment of the pressure-resistant, grid-reinforced, environmentally friendly cardboard box of this utility model, the grid reinforcement component includes a first reinforcement partition, a first slot, a second reinforcement partition, and a second slot. Two sets of the first reinforcement partition are provided, and the first reinforcement partition is inserted into the inner wall of the guide groove on the side surface of the second horizontal bar. Two sets of parallel first slots are provided on the surface of each first reinforcement partition. Two sets of the second reinforcement partition are provided, and the second reinforcement partition is inserted into the inner wall of the guide groove on the side surface of the first horizontal bar. Two sets of parallel second slots are provided on the surface of each second reinforcement partition.

[0010] As a preferred embodiment of the pressure-resistant, grid-reinforced, environmentally friendly cardboard box of this utility model, the two sets of first and second reinforcing partitions can be interlocked with each other through the first and second slots on their surfaces to form a grid shape.

The side surface of the first reinforcing partition is provided with raised stripes that match the strip groove on the side surface of the snap-fit ​​block.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] In this invention, the frame reinforcement component is inserted into the inside of the carton body and is limited by the engagement of the limiting slot and the limiting block.

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.

[0023] Please see Figures 1-6 The present invention provides the following technical solution: a pressure-resistant, grid-reinforced, environmentally friendly cardboard box, comprising a cardboard box body 1 and a cover plate 2 connected to the opening edge of the cardboard box body 1. The inside of the cardboard box body 1 is provided with a frame reinforcement component 3. The frame reinforcement component 3 is provided with a limiting component 4 connected to the cardboard box body 1. The inner wall of the frame reinforcement component 3 is connected with a guide groove 6. The inner wall of the frame reinforcement component 3 is provided with a grid reinforcement component 5 inserted into the inner wall of the guide groove 6. The side surface of the grid reinforcement component 5 is provided with a positioning component 7 connected to the frame reinforcement component 3.

[0024] Preferably, the edge reinforcement component 3 includes four corner reinforcement strips 301, four first horizontal strips 302 and four second horizontal strips 303. The corner reinforcement strips 301 are located at the four corners of the inner wall of the carton body 1. Two first horizontal strips 302 are connected between two corner reinforcement strips 301 and two second horizontal strips 303 are connected between two corner reinforcement strips 301.

[0025] Preferably, the dimensions of the frame reinforcement component 3 formed by the four sets of corner reinforcement strips 301, the first horizontal strip 302 and the second horizontal strip 303 are adapted to the inner wall dimensions of the carton body 1.

[0026] In practical use, the frame reinforcement component 3, formed by four sets of corner reinforcement strips 301, the first horizontal strip 302 and the second horizontal strip 303, is set on the inner wall of the carton body 1. The corners of the carton body 1 can be processed by the corner reinforcement strips 301, thereby improving the stability of the carton body 1.

[0027] Preferably, the limiting component 4 includes a limiting block 401 and a limiting slot 402. The inner wall of the carton body 1 is connected to a T-shaped limiting block 401, and the side surface of the first horizontal bar 302 is provided with a limiting slot 402 that is adapted to the limiting block 401.

[0028] In practical use, when installing the frame reinforcement component 3, the first horizontal bar 302's surface limiting slot 402 engages with the limiting block 401, which can limit the frame reinforcement component 3 and thus increase the stability of the frame reinforcement component 3 after installation.

[0029] Preferably, the grid-like reinforcement component 5 includes a first reinforcement partition 501, a first slot 502, a second reinforcement partition 503, and a second slot 504. Two sets of first reinforcement partitions 501 are provided, and the first reinforcement partitions 501 are inserted into the inner wall of the guide groove 6 on the side surface of the second horizontal bar 303. Two sets of parallel first slots 502 are provided on the surface of each first reinforcement partition 501. Two sets of second reinforcement partitions 503 are provided, and the second reinforcement partitions 503 are inserted into the inner wall of the guide groove 6 on the side surface of the first horizontal bar 302. Two sets of parallel second slots 504 are provided on the surface of each second reinforcement partition 503.

[0030] Preferably, the two sets of first reinforcing partitions 501 and second reinforcing partitions 503 can be interlocked with each other through the first slot 502 and the second slot 504 on their surfaces to form a grid shape.

[0031] In practical use, the first reinforcing partition 501 and the second reinforcing partition 503 are connected by mutual plugging, which makes it convenient to assemble and disassemble the first reinforcing partition 501 and the second reinforcing partition 503.

[0032] Preferably, the positioning component 7 includes a positioning block 701 and a snap-fit ​​block 702. A positioning block 701 is connected to the top side surface of the first reinforcing partition 501 and the second reinforcing partition 503. A snap-fit ​​block 702 is fitted into the inner wall of the carton body 1. A strip groove is provided on the surface of the snap-fit ​​block 702. The first reinforcing partition 501 is made of rubber. The side surface of the first reinforcing partition 501 is provided with raised stripes that match the strip groove on the side surface of the snap-fit ​​block 702.

[0033] In practical use, the first reinforcing partition 501 and the second reinforcing partition 503 can be fixed to the inner wall of the frame reinforcing component 3 by the engagement between the snap-fit ​​block 702 and the positioning block 701.

[0034] Working principle: First, the frame reinforcement component 3 is inserted into the inside of the carton body 1. When the frame reinforcement component 3 is inserted into the bottom of the carton body 1, the limiting block 401 drives the limiting slot 402 to lock onto the surface of the limiting block 401. Then, the two first reinforcement partitions 501 are respectively inserted into the inner wall of the guide groove 6 of the inner wall of the first horizontal bar 302. When the first reinforcement partition 501 drives the positioning block 701 to move to the end of the locking block 702, the positioning block 701 is squeezed and can deform. When the first reinforcement partition 501 is inserted downward to the bottom, the raised stripes on the side surface of the positioning block 701 restore their deformation and engage with the strip groove on the side surface of the locking block 702. In this way, the position of the first reinforcement partition 501 can be fixed.

[0035] Next, the two second reinforcing partitions 503 are respectively inserted into the inner wall of the guide groove 6 on the inner wall of the second horizontal bar 303. During the downward sliding process, the second reinforcing partition 503 can be inserted into the first slot 502 on the surface of the first reinforcing partition 501 through the second slot 504. When the second reinforcing partition 503 moves down to the bottom, the position of the second reinforcing partition 503 is fixed by the engagement of the positioning block 701 and the snap-fit ​​block 702. In this way, the overall compression resistance of the carton body 1 can be increased by the cooperation of the corner reinforcing strip 301 and the grid reinforcing component 5.

[0036] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
