[0002] In the modern logistics and packaging field, cardboard boxes have become the preferred packaging choice due to their advantages such as low cost, lightweight, environmental friendliness, and recyclability, playing a crucial role in the transportation, storage, and sales of goods. Especially with the booming e-commerce industry and the explosive growth of express delivery volume, the use of cardboard boxes has increased daily, highlighting their growing importance. Currently, among various cardboard box sealing operations, using tape is the most common method. Tape sealing is widely adopted due to its ease of operation and a certain degree of airtightness.

[0003] However, from the perspective of ease of unpacking, opening a cardboard box sealed with tape often requires the use of tools such as scissors or utility knives to cut the tape. This process is not only cumbersome but also poses a safety hazard for those unfamiliar with the tools. Furthermore, after prolonged application, the tape adheres tightly to the box surface, easily damaging the surface when removed, reducing the box's reusability and resulting in resource waste. The extensive use of tape also raises certain environmental concerns.

[0004] To ensure both ease of opening and security while sealing the box, and to avoid the resource waste and environmental problems caused by using tape for sealing, we propose a segmented self-locking fastening carton. Utility Model Content

[0023] 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.

[0024] Please see Figure 1-5 This utility model provides a technical solution: a segmented self-locking fastening carton, including a carton body 1, two sets of first folding plates 2 are provided on the carton body 1, two sets of second folding plates 3 are provided on the carton body 1, two sets of L-shaped insert plates 5 are provided on the first folding plates 2, and several sets of second slots 8 that match the L-shaped insert plates 5 are opened on the carton body 1.

[0025] When in use, first bend the two sets of second folding plates 3 inward, then bend the two sets of first folding plates 2 inward, and then bend the L-shaped insert plate 5 to insert it into the second slot 8 to achieve self-locking. The box can be sealed without the use of tape. The sealing process is convenient and easy to open. No other tools are needed, and the security is better. At the same time, it avoids the resource waste and environmental problems caused by using tape to seal the box.

[0026] The upper surface of the second folding plate 3 is provided with several sets of limiting blocks 6, and the first folding plate 2 is provided with several sets of limiting holes 4 that match the limiting blocks 6.

[0027] After the first fold plate 2 is bent, the limiting block 6 on the second fold plate 3 is inserted into the limiting hole 4 on the first fold plate 2. When the first fold plate 2 tends to open, the limiting block 6 can block the first fold plate 2 and limit the first fold plate 2 to a certain extent. In conjunction with the L-shaped insert plate 5, the self-locking is more secure.

[0028] The L-shaped insert plate 5 is provided with several sets of insert blocks 14, and the housing 1 is provided with several sets of first slots 7 that match the insert blocks 14. The top of the insert block 14 abuts against the lower surface of the second folding plate 3.

[0029] When the L-shaped insert 5 is inserted into the second slot 8, the insert block 14 is simultaneously inserted into the first slot 7, which increases the insertion stability of the L-shaped insert 5 to a certain extent. At the same time, the insert block 14 lifts up the second folding plate 3 to prevent the second folding plate 3 from sagging, ensuring that the limiting block 6 is inserted into the limiting hole 4, thus ensuring the stability of self-locking.

[0030] The insert 14 has a bevel. This makes it easier for the insert 14 to be inserted into the first slot 7 and to lift the second folding plate 3.

[0031] The box 1 is provided with several sets of first partitions 9, and several sets of mounting strips 13 are fixedly connected to the inner wall of the box 1. The mounting strips 13 are provided with sliding grooves, and the first partitions 9 are slidably connected to the sliding grooves.

[0032] The housing 1 is provided with several sets of second partitions 10, and several sets of first positioning grooves 11 corresponding to the first partition 9 are provided on the second partitions 10. Several sets of second positioning grooves 12 matching the first positioning grooves 11 are provided on the first partition 9.

[0033] The inner cavity of the box 1 is divided into multiple small spaces by the cooperation of the first partition 9 and the second partition 10. This can separate and fix the items placed in the box 1, preventing multiple items from colliding and causing damage during transportation. The size of the partition space can be adjusted by increasing or decreasing the number of the first partition 9 and the second partition 10 or changing the position of the first partition 9 and the second partition 10, so as to accommodate items of different sizes.

[0034] Working principle: In use, first bend the two sets of second folding plates 3 inward, then bend the two sets of first folding plates 2 inward, and then bend the L-shaped insert 5 to insert it into the second slot 8 to achieve self-locking. After the first folding plate 2 is bent, the limiting block 6 on the second folding plate 3 is inserted into the limiting hole 4 on the first folding plate 2. When the first folding plate 2 tends to open, the limiting block 6 can block the first folding plate 2, limiting it to a certain extent. This, together with the L-shaped insert 5, makes the self-locking more secure. When the L-shaped insert 5 is inserted into the second slot 8, the insert block 14 is simultaneously inserted into the first slot 7, which increases the insertion stability of the L-shaped insert 5 to a certain extent. At the same time, the insert block 14 lifts the second folding plate 3 to prevent it from sagging, ensuring that the limiting block 6 is inserted into the limiting hole 4, thus ensuring the stability of the self-locking. The self-locking structure allows for sealing without tape, making the process convenient and easy to open. No other tools are needed, enhancing security and avoiding the resource waste and environmental problems associated with tape sealing. The first partition 9 and the second partition 10 work together to divide the interior of the box 1 into multiple small spaces, effectively separating and securing items within to prevent damage from collisions during transport. The size of these spaces can be adjusted by increasing or decreasing the number or position of the first and second partitions 9 and 10, thus accommodating items of different sizes.
