Description

Technical Field

[0001] This utility model relates to the technical field of aquatic product transportation packaging boxes, specifically a packaging box for transporting freshwater crabs. Background Technology

[0002] Freshwater crabs are crustaceans that live in freshwater environments. They mainly include species such as the Chinese mitten crab (Eriocheir sinensis), freshwater crab, and stone crab, and are widely distributed in rivers, lakes, and other bodies of water. Due to the delicious taste of freshwater crab meat, freshwater crab farming has gradually become one of the important aquaculture projects in my country. After maturing, some large, high-quality freshwater crabs require specialized packaging boxes for transportation to ensure they remain fresh upon arrival at their destination.

[0003] A Chinese patent, publication number CN219687931U, describes a crab express packaging box, which includes: "A crab express box and a sealed top cover. The crab express box has a crab placement box inside for placing crabs, and an ice pack placement box at the bottom of the crab placement box for keeping the crabs at a low temperature. This utility model arranges the crabs in a crab placement groove with a slope structure on one side and a bottom on the other, so that the crabs are arranged in sequence to prevent them from piling up. The ice pack placement box holds frozen ice packs, which are connected to the crab placement groove through a first through hole at the bottom, keeping the bottom of the crabs at a low temperature, ensuring uniform temperature distribution inside the box, improving the low-temperature preservation effect, maintaining a low temperature during transportation, extending the survival time of the crabs, ensuring the survival rate of the crabs, and guaranteeing product quality."

[0004] Through our research on the aforementioned technologies, we found that when using this technology, crabs are placed in a crab arrangement slot. Due to the lack of a restraining structure for the crabs, they are prone to shaking during transportation, resulting in multiple crabs becoming disorganized and colliding within the box, potentially causing injury and reducing their freshness. Therefore, based on this situation, we have specifically designed a packaging box for transporting freshwater crabs. Utility Model Content

[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] Please see Figure 1-6 A packaging box for transporting freshwater crabs includes a box body 1 and a box lid 12. Ventilation holes are evenly distributed on the box body 1 to facilitate ventilation inside and outside the box. A positioning groove 3 is provided on the top edge of the box body 1. A positioning block 13 is fixed at the bottom of the box lid 12 at a position corresponding to the positioning groove 3. The box lid 12 is inserted into the positioning groove 3 through the positioning block 13 and fastened to the box body 1. A placement plate 2 is provided inside the box body 1. An installation groove 4 is provided on the top of the placement plate 2, and a limit component is provided on the inner bottom wall of the installation groove 4. The limiting component includes a support block 5 and a limiting frame 7. The limiting frame 7 is fixed on both sides of the top of the support block 5. The top of the support block 5 has a groove, in which a sponge block 6 is placed. A sponge sheet is also fixed on the inner wall of the limiting frame 7, which can provide a good soft effect for the sides of the crab and protect the sides of the crab. The box cover 12 is set on the top of the box body 1, and a stop block 14 is fixed at the bottom of the box cover 12 at the position corresponding to the sponge block 6. A sponge block 15 is fixed at the bottom of the stop block 14.

[0028] Please see Figure 2 , Figure 4 as well as Figure 5 In this embodiment, two placement plates 2 are provided inside the box 1, multiple sets of limiting components are evenly arranged on the inner bottom wall of the mounting groove 4, and the support block 5 is fixedly connected to the inner bottom wall of the mounting groove 4.

[0029] Specifically, both placement plates 2 and each placement plate 2 have multiple sets of limiting components, which can facilitate the transportation of a large number of crabs at one time, improve transportation efficiency, and each crab is individually limited to avoid mutual interference.

[0030] Please see Figure 2 as well as Figure 4 In this embodiment, the two limiting frames 7 located at the top of the support block 5 are far apart from each other and have a gap between them, and the multiple support blocks 5 are far apart from each other and have gaps between them.

[0031] Specifically, there is a gap between the two corresponding limiting frames 7, which is intended to facilitate the subsequent removal of the crab from the limiting frame 7 by the staff. This makes it easy to put in and take out the crab. The multiple support blocks 5 are far apart from each other, which makes it easy for the staff to place the ice packs used for cooling in the gaps between the multiple support blocks 5.

[0032] Please see Figure 3 as well as Figure 5 In this embodiment, a stop block 14 and a second sponge block 15 are also fixed at the bottom of the placement plate 2. Multiple stop blocks 14 and second sponge blocks 15 are provided at the bottom of the placement plate 2 and the bottom of the box cover 12, and the positions of the stop blocks 14 and second sponge blocks 15 correspond to the top of the support block 5.

[0033] Specifically, both placement boards 2 have the same stop block 14 and sponge block 15 at the bottom, which allows the placement boards 2 to be placed arbitrarily when placed into the box 1. Either placement board 2 can be placed on the upper or lower layer inside the box 1, making it convenient to use.

[0034] Please see Figure 2 as well as Figure 5 In this embodiment, handles 8 are fixed on both sides of the top of the placement plate 2. The height of the handles 8 is the same as the height of the limiting frame 7, and one side of the handles 8 is away from the side of the limiting frame 7.

[0035] Specifically, the handle 8 allows staff to easily grasp and conveniently remove or place the placement plate 2 from the box 1.

[0036] Please see Figure 2 , Figure 4 as well as Figure 5 In this embodiment, two water tanks 10 are opened in the inner cavity of the placement plate 2, which are far apart from each other. The water tanks 10 are located below the support block 5. The side of the placement plate 2 is provided with a through hole communicating with the water tanks 10, and a sealing plug 9 is provided in the through hole. A water-absorbing line 11 is connected to the bottom of the sponge block 6. The bottom of the support block 5 and the inner bottom wall of the mounting groove 4 are provided with perforations to facilitate the water-absorbing line 11 to pass through into the water tank 10.

[0037] Specifically, the water absorption line 11 has a certain water absorption capacity, which can transfer the water in the water tank 10 to the sponge block 6. The water absorption capacity of the sponge block 6 can maintain the moisture of the crabs placed on it and improve the freshness rate of the crabs during transportation. The side of the placement plate 2 has through holes, which can facilitate the addition of water to the water tank 10 and the subsequent drainage of water from the water tank 10. The rubber sealing plug 9 can seal the water tank 10.

[0038] In use: Workers can place the tied freshwater crabs on top of the two placement boards 2, and then place the crabs between the two limiting frames 7. The enclosure structure formed between the two limiting frames 7 prevents the crabs from swaying back and forth or side to side during transportation. After crabs are placed in multiple limiting frames 7 on both placement boards 2, workers can place the two placement boards 2 sequentially into the box body 1, allowing the two placement boards 2 to overlap in the box body 1. When overlapping, the bottom baffle 14 and sponge block 15 of the upper placement board 2 enter the corresponding two limiting frames 7 of the lower placement board 2. This achieves the effect of covering the top of the two limiting frames 7 to prevent the crab from shaking up and down during transportation. Ultimately, the crab is protected by soft sponge blocks on both the top and bottom. Then, the lid 12 can be fastened to the top of the box body 1. The positioning block 13 enters the positioning groove 3 to position the lid 12. The bottom block 14 of the lid 12 and the sponge block 15 also enter the corresponding two limiting frames 7 of the upper placement plate 2 to cover the upper limiting frames 7. Then, tape can be used to bond the connection between the lid 12 and the box body 1 to stabilize the lid 12 on the box body 1.

[0039] During transportation, since the water absorption line 11 is placed in the water tank 10, water can be delivered to the sponge block 6 to keep the sponge block 6 moist, thereby ensuring that the crabs placed on the sponge block 6 remain moist and increasing the probability of the crabs being fresh during transportation.
