[0002] In the cold chain logistics industry, transport boxes are the most common storage and transportation equipment in the cold chain. Currently, existing transport boxes generally have insufficient safety during the unloading process, especially for fresh produce with fragile skin, which is easily damaged during unloading.

This utility model includes a transportation box and a support frame. The support frame is located between the bottom wall and the side wall of the transportation box and has an L-shaped structure. The bottom wall of the transportation box is inclined, and the side wall of the transportation box has an opening with a baffle on the opening. A clamp assembly is provided between the baffle and the transportation box, and the top wall of the transportation box has a cover assembly. In the above structure, although the inclined bottom wall of the transportation box allows for quick unloading of goods, in practical applications, when fresh goods with fragile skin slide out from the inclined bottom wall, the impact due to inertia can easily cause damage to the fresh goods. That is, the problem of easy damage to goods during the unloading process of the transportation box exists. Therefore, we need to propose a cold chain storage transportation box. Utility Model Content

By setting up the transport box body, the placement plate and the moving mechanism, the placement plate can be moved horizontally outside the transport box body to facilitate unloading, thereby solving the problems mentioned in the background art.

[0014] This utility model utilizes the coordinated design of the transport box body, the placement plate, and the moving mechanism. The pull-out component in the moving mechanism allows workers to easily drive the placement plate horizontally, while the sliding component at the bottom of the placement plate provides stable guidance, effectively reducing jamming and offset during the movement of the placement plate.

[0022] 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.

[0023] Please see Figure 1-6 This utility model provides a technical solution:

[0024] A transport box for cold chain storage includes: a transport box body 1; a placement plate 2 disposed at the inner bottom of the transport box body 1; and a moving mechanism 3 for horizontally moving the placement plate 2, wherein the moving mechanism 3 is disposed at the bottom of the placement plate 2; the moving mechanism 3 includes a pull-out member 31 and a sliding member 32; the pull-out member 31 is disposed inside the placement plate 2, and the sliding member 32 is disposed at the bottom of the placement plate 2.

[0025] In this embodiment, the coordinated operation of the transport box body 1, the placement plate 2, and the moving mechanism 3 changes the traditional unloading method that relies on the inclined bottom wall of the transport box to allow goods to slide out. By using the moving mechanism 3 to achieve horizontal movement of the placement plate 2, it is possible to avoid collisions and squeezing of fragile fresh goods due to inertial impact during unloading, effectively reducing damage to goods and ensuring the quality and integrity of goods after transportation. The moving mechanism 3 is designed as a pull-out component 31 and a sliding component 32. The pull-out component 31 allows workers to easily drive the placement plate 2 to move through simple operation, reducing the difficulty of manual operation. The sliding component 32 provides stable support and guidance for the horizontal movement of the placement plate 2, reducing jamming and deviation problems during movement, making the unloading process smoother and more controllable, and improving the overall unloading efficiency. At the same time, the independent placement plate 2, combined with the horizontally movable structure, not only meets the storage and unloading needs of fragile goods such as fresh goods, but is also compatible with other cold chain goods that need to be handled smoothly and avoid sliding damage, thus broadening the applicable scenarios of the transport box and enhancing the practicality of the equipment.

[0026] The pull-out component 31 includes two sets of pull rods 311, two sets of limiting posts 312, a pull plate 313, two sets of first sliding holes 314, and two sets of second sliding holes 315. The two sets of first sliding holes 314 are symmetrically opened on one side of the placement plate 2, and the two sets of second sliding holes 315 are symmetrically opened inside the placement plate 2. The two sets of first sliding holes 314 are connected to the two sets of second sliding holes 315. The two sets of pull rods 311 are slidably disposed in the two sets of first sliding holes 314, and the two sets of second limiting posts 312 are slidably disposed in the two sets of second sliding holes 315. One end of the two sets of pull rods 311 is fixedly connected to one end of the two sets of limiting posts 312, and the other end of the two sets of pull rods 311 is fixedly connected to one side of the pull plate 313.

[0027] Specifically, staff only need to pull the pull plate 313 to move the two sets of pull rods 311 synchronously, thereby driving the placement plate 2. This eliminates the need for complex operations and significantly reduces the difficulty of manual operation. The pull rods 311 are fixedly connected to the limiting posts 312 and slide within the first sliding hole 314 and the second sliding hole 315, respectively. The limiting posts 312 effectively restrict the movement range of the pull rods 311, preventing them from coming out of the sliding holes and ensuring that the parts do not fall off during the pulling process, thus guaranteeing reliable operation of the mechanism. Furthermore, the two sets of first sliding holes 314 and second sliding holes 315 are symmetrically arranged. Together with the symmetrical pull rods 311 and limiting posts 312, the force of the pull plate 313 can be evenly transmitted to the placement plate 2, preventing the placement plate 2 from tilting or jamming due to uneven force. This ensures that the placement plate 2 remains stable during horizontal movement, further protecting the perishable goods such as fresh produce inside the box.

[0028] A storage slot 4 is provided on one side of the placement plate 2 for the pull plate 313 to be hidden and stored, and an arc-shaped groove 5 is provided on the top of the pull plate 313.

[0029] The storage slot 4 can hide the pull plate 313, preventing it from protruding during transportation and causing collision damage or misoperation, thus reducing space occupation. The arc-shaped groove 5 conforms to the natural curvature of the human hand, allowing staff to easily insert their fingers into the arc-shaped groove 5 to pry out the pull plate 313 without the need for tools. This avoids the problem of difficulty in applying force due to the smooth surface of the pull plate 313, and also reduces discomfort during hand operation, significantly improving the convenience of pulling out the pull plate 313.

[0030] The diameters of the two sets of limiting posts 312 are larger than the diameters of the two sets of pull rods 311, and the diameters of the two sets of second sliding holes 315 are larger than the diameters of the two sets of first sliding holes 314.

[0031] Specifically, the diameter difference design between the limiting post 312 and the pull rod 311, and between the second sliding hole 315 and the first sliding hole 314, can effectively prevent the limiting post 312 from coming out of the second sliding hole 315 and the pull rod 311 from coming out of the first sliding hole 314, providing structural constraints for the stable operation of the pull-out component 31 and ensuring the safety and reliability of the pull-out process.

[0032] The sliding component 32 includes two sets of sliding blocks 321, two sets of sliding grooves 322, a limiting block 323, and a limiting groove 324. Both sets of sliding blocks 321 are fixedly installed at the bottom of the placement plate 2. The inner bottom of the transport box body 1 is provided with two sets of sliding grooves for the sliding blocks 321 to slide. The limiting block 323 is fixedly installed at the bottom of the placement plate 2 and is located between the two sets of sliding blocks 321. The inner bottom of the transport box body 1 is provided with a limiting groove 324 for the limiting block 323 to slide.

[0033] In a further preferred embodiment, the two sets of sliding blocks 321 at the bottom of the placement plate 2 cooperate with the two sets of sliding grooves at the bottom of the transport box body 1 to provide precise guidance for the horizontal movement of the placement plate 2, effectively reducing the jamming and offset problems that occur during the movement of the placement plate 2, ensuring that the placement plate 2 moves the goods in the box smoothly, and avoiding damage to fresh and other fragile goods due to shaking and collision. Secondly, the limiting block 323 located between the two sets of sliding blocks 321 cooperates with the limiting groove 324 in the transport box body 1 to limit the movement range of the placement plate 2, preventing the placement plate 2 from completely detaching from the transport box body 1 due to improper force control when the staff pulls out the placement plate 2, avoiding damage to the goods caused by the placement plate 2 falling down, and improving operational safety.

[0034] It also includes a limiting mechanism 6 for limiting and fixing both sides of the placement plate 2, and the limiting mechanism 6 is located on both sides of the transport box body 1.

[0035] The limiting mechanism 6 can fix both sides of the placement plate 2 during transportation, preventing the placement plate 2 from shaking or shifting due to transportation bumps, avoiding damage to the goods inside the transport box body 1 from mutual collision, and improving the stability and safety of goods transportation.

[0036] The limiting mechanism 6 includes two sets of fixed cylinders 61, two sets of threaded rods 62, two sets of anti-detachment rings 63, two sets of threaded holes 64, two sets of through holes 65, and two sets of limiting holes 66. The two sets of fixed cylinders 61 are fixedly installed on both sides of the transport box body 1. The two sets of threaded rods 62 are slidably disposed in the two sets of fixed cylinders 61. The two sets of anti-detachment rings 63 are fixedly installed on the outer sides of the two sets of threaded rods 62. Limiting holes 66 for the movement of anti-detachment rings 63 are opened on the opposite side of the two sets of fixed cylinders 61, and the inner walls of the two sets of limiting holes 66 are adapted to the inner walls of the two sets of anti-detachment rings 63. Threaded holes 64 for threaded connection of threaded rods 62 are opened on both sides of the placement plate 2. Through holes 65 for threaded rods 62 to pass through and move are opened on both sides of the transport box body 1.

[0037] Specifically, the symmetrical arrangement of the two sets of fixing cylinders 61 and threaded rods 62, through the threaded connection of the threaded rods 62 to the threaded holes 64 on both sides of the placement plate 2, can form a balanced and stable fixation on the placement plate 2 from both sides, effectively preventing the placement plate 2 from shifting or shaking due to bumps during transportation, and avoiding damage to the goods inside the box due to collision. The threaded rods 62 can slide flexibly within the fixing cylinders 61, and in conjunction with the through holes 65 on both sides of the transport box body 1, the fixing and unfixing operations are simple and efficient, and can be completed without complicated tools, reducing the intensity of manual operation. The matching structure of the anti-detachment ring 63 and the upper limit hole 66 of the fixing cylinder 61 can accurately limit the movement range of the threaded rods 62, preventing the threaded rods 62 from accidentally coming out of the fixing cylinders 61, ensuring that the limiting mechanism 6 always maintains structural integrity and reliable use. The overall structure achieves a tight fit through mechanical connection, which not only ensures the stability during fixing, but also takes into account the convenience during unfixing, providing dual protection for the safety of cargo transportation and the efficiency of unloading.

[0038] Working principle: When using this utility model, first open the door on the transport box body 1, then rotate the threaded rod 62 on one side to disengage the threaded rod 62 from the threaded hole 64 on the corresponding side of the placement plate 2. During this process, the threaded rod 62 moves inside the fixed cylinder 61, and the anti-detachment ring 63 on its outer side slides synchronously in the limiting hole 66 of the fixed cylinder 61 to prevent the threaded rod 62 from coming out of the fixed cylinder 61. When one end of the threaded rod 62 moves into the through hole 65 of the transport box body 1, the fixation of one side of the placement plate 2 is released. The threaded rod 62 on the other side can be operated in the same way to release the overall fixation of the placement plate 2.

[0039] After the placement plate 2 is released, the staff holds the arc-shaped groove 5 on the top of the pull plate 313 and pulls the pull plate 313 out of the storage slot 4 on one side of the placement plate 2. When the pull plate 313 is pulled out, it will drive the two sets of pull rods 311 to slide in the two sets of first sliding holes 314 of the placement plate 2. At the same time, the pull rods 311 drive the two sets of limiting posts 312 fixed to them to move synchronously in the two sets of second sliding holes 315 inside the placement plate 2. Since the diameter of the limiting post 312 is larger than the diameter of the pull rod 311 and the diameter of the second sliding hole 315 is larger than the diameter of the first sliding hole 314, it can effectively prevent the limiting post 312 from coming out of the second sliding hole 315, ensuring the stability of the pulling process.

[0040] While the pull-out component 31 moves the placement plate 2, the two sets of sliding blocks 321 at the bottom of the placement plate 2 slide in the two sets of sliding grooves at the bottom of the transport box body 1, providing stable guidance for the horizontal movement of the placement plate 2 and preventing jamming or deviation during movement. At the same time, the limiting block 323 at the bottom of the placement plate 2, located between the two sets of sliding blocks 321, slides in the limiting groove 324 at the bottom of the transport box body 1. The cooperation between the limiting block 323 and the limiting groove 324 can prevent the placement plate 2 from completely detaching from the transport box body 1, and finally allow the placement plate 2 to move smoothly and horizontally out of the transport box body 1. The staff can then directly take and put goods on the placement plate 2 to complete the safe unloading.
