[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Please refer to Figure 1-3 A cold chain logistics transport box for watermelons and melons comprises a main box body 1, the top and bottom of the main box body 1 are both equipped with sub-box bodies 2 for connecting and fixing the main box body 1, the inner cavity of the main box body 1 is rotatably connected with a bidirectional screw rod 3, the bidirectional screw rod 3 passes through the main box body 1 and extends to the front of the main box body 1, the front of the bidirectional screw rod 3 is fixedly connected with a crank 21, the outer ring of the bidirectional screw rod 3 is threadedly connected to a movable plate 4, the bottom of the movable plate 4 is fixedly connected with a clamping plate 5 for clamping the watermelon, the bottom of the clamping plate 5 is provided with an arc-shaped groove 6, and the inner wall of the arc-shaped groove 6 is fixedly connected with a sponge pad.

[0023] A connecting plate 7 is fixedly connected to the inner cavity of the main box body 1 , a supporting plate 8 is fixedly connected to the top of the connecting plate 7 , and a placement groove 9 is provided in the inner cavity of the supporting plate 8 .

[0024] The inner wall of the main box body 1 is fixedly connected to the limit rod 10 , and the movable plate 4 is slidably sleeved on the outer ring of the limit rod 10 .

[0025] In the embodiment of the present invention, rotating the crank 21 rotates the bidirectional screw 3, which in turn moves the threaded movable plate 4. Since the threads of the bidirectional screw 3 are bidirectional, the movable plates 4 move closer together, and the clamping plates 5 move closer together, securing the top of the watermelon via the arc-shaped groove 6 and the sponge pad.

[0026] Please refer to Figure 1-4 A protective frame 11 is fixedly connected to the left side of the front of the main box body 1, a recording board 12 is installed on one side of the protective frame 11, and a placement frame 13 is installed at the bottom of the recording board 12. The inner cavity of the main box body 1 is provided with air holes 14, and the air holes 14 are distributed in a matrix array.

[0027] The top and bottom of the main box body 1 are fixedly connected to the limit plate 15, and a limit groove 16 is provided on the side of the auxiliary box body 2 close to the main box body 1. The limit plate 15 is slidably connected in the inner cavity of the limit groove 16. The auxiliary box body 2 is a hollow structure. Limiting holes 17 are provided on both sides of the main box body 1, and limiting blocks 18 are hinged on both sides of the auxiliary box body 2. One side of the limit block 18 is fixedly connected to the limiting column 19. The sizes of the limiting hole 17 and the limiting column 19 match each other. The limiting holes 17 and the limiting blocks 18 are distributed in multiple groups of matrix arrays. The limit block 18 is fixedly connected to a magnetic suction piece 20 on the side close to the auxiliary box body 2.

[0028] In the embodiment of the present invention, after the main case 1 and the auxiliary case 2 are fixed together, the limit block 18 can be rotated and the limit post 19 can be inserted into the inner cavity of the limit hole 17 to further complete the fixation between the main case 1 and the auxiliary case 2, thereby improving the stability of the main case 1. When the limit block 18 is not in use, the limit block 18 can be placed in close contact with the auxiliary case 2. The magnetic force between the magnetic sheet 20 and the auxiliary case 2 will keep the limit block 18 in a vertical position, avoiding damage caused by moving the case.

[0029] During use, the watermelon to be transported is placed in the inner cavity of the placement groove 9 of the support plate 8. The placement groove 9 will fix the bottom of the watermelon to a certain extent. Then, the crank 21 is turned to drive the bidirectional screw rod 3 to rotate. During the rotation of the bidirectional screw rod 3, the movable plate 4 connected by the thread will be driven to move. Since the thread of the bidirectional screw rod 3 is bidirectional, it will drive the movable plate 4 to approach each other, and drive the clamping plate 5 to approach each other, and fix the top of the watermelon through the arc groove 6 and the sponge pad. Through the cooperation of the bidirectional screw rod 3 and the clamping plate 5, watermelons of different sizes can be fixed, which not only expands the compatibility of the transport box with watermelons of different sizes, but also avoids the problem of cumbersome operation and inconvenience caused by the use of a viscose-like structure.

[0030] After the watermelons are fixed, air can be exchanged to the outside through the air vents 14, and ventilation and corrosion prevention are achieved through the auxiliary boxes 2 at the top and bottom. The auxiliary boxes 2 are hollow in structure and are fixedly connected to the main box 1 via the limiting grooves 16 and the limiting plates 15. Therefore, multiple groups of main boxes 1 can be fixed to each other through the auxiliary boxes 2, meeting the needs of transportation. The hollow structure of the auxiliary boxes 2 also meets the ventilation needs of the watermelons inside the main box 1.

[0031] After the main case 1 and the auxiliary case 2 are secured together, the stopper 18 can be rotated and the stopper post 19 inserted into the inner cavity of the stopper hole 17 to further secure the main case 1 and the auxiliary case 2, thereby improving the stability of the main case 1. When the stopper 18 is not in use, it can be placed close to the auxiliary case 2. The magnetic force between the magnetic sheet 20 and the auxiliary case 2 will keep the stopper 18 in an upright position, preventing damage caused by transporting the case.

[0032] The protection frame 11 located on the front of the main box body 1 will protect the crank 21. The recording board 12 located on one side of the protection frame 11 can record the current time of picking and transporting the watermelon, and the staff can place some anti-corrosion and anti-rot drugs in the placement slot 9 to avoid damage to the watermelon during transportation.

[0033] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
