[0019] The utility model will be described in detail in combination with the drawings and examples.

[0020] A kind of moisture-resistant corrugated box, such as Figures 1 to 3As shown, the carton includes a body 1. A coated paper is attached to the outer wall of the body 1. The coated paper is a composite material made by coating plastic particles onto the surface of paper using a casting machine. Its main features are oil and water resistance, improving the waterproof effect of the carton. Four fixing rods 7 are arrayed on the side wall of the body 1. Connecting straps 8 are provided between adjacent fixing rods 7. Several connecting straps 8 and fixing rods 7 together form a protective strap to restrain the upper body 1. When the upper body 1 is about to slide relative to the lower body 1 due to the acceleration and deceleration of the vehicle, the connecting straps 8 provide lateral support to the upper body 1, preventing the upper body 1 from sliding relative to the lower body 1, keeping the upper body 1 relatively stationary, and preventing the upper body 1 from sliding off the top surface of the lower body 1. Protective straps can be formed between the upper and lower layers of stacked body 1, achieving the effect of preventing relative displacement between body 1s and causing the body 1s to scatter.

[0021] like Figures 1 to 3 As shown, the length of the connecting strap 8 is the same as the length of the side wall of the body 1 corresponding to the connecting strap 8. If the length of the connecting strap 8 is too long, it will weaken the binding force on the body 1. The length of the connecting strap 8 being the same as the length of the side wall of the corresponding body 1 can provide a more suitable binding force for the body 1. The material of the connecting strap 8 is set as canvas webbing. This material has small deformation, strong structure, and can withstand more impact. A snap fastener 10 is attached to the connecting strap 8. The diameter of the snap fastener 10 is larger than the diameter of the end of the connecting strap 8. A snap-fit ​​groove 6 is opened on the fixing rod 7. The snap fastener 10 is snapped into the snap-fit ​​groove 6 from above. The side impact will not cause the snap fastener 10 to separate from the snap-fit ​​groove 6. The snap-fit ​​method facilitates the connection and separation between the connecting strap 8 and the adjacent fixing rod 7.

[0022] like Figures 1 to 3 As shown, a storage cavity 5 for storing the connecting strap 8 is provided near the top surface inside the fixed rod 7. A rotating rod 9 is rotatably connected to the inner wall of the storage cavity 5. One end of the connecting strap 8 is glued to the rotating rod 9. A groove 4 communicating with the storage cavity 5 is provided on the fixed rod 7. The connecting strap 8 is slidably connected to the groove 4. The connecting strap 8 can slide out of the storage cavity 5 or be stored back into the storage cavity 5 from the outside by sliding in the groove 4.

[0023] like Figures 1 to 3As shown, the main body 1 has several sliding grooves 2. The fixed rod 7 is movably connected to the sliding groove 2. The fixed rod 7 can slide and rotate within the sliding groove 2. The bottom surface of the fixed rod 7 is fixedly connected to a limiting rod 13. The sliding groove 2 has two limiting grooves 3 that are detachably connected to the limiting rod 13 near the side wall of the main body 1. By rotating the fixed rod 7, the engagement and disengagement states between the limiting rod 13 and the limiting groove 3 can be switched. The limiting rod 13 is used to fix the position of the fixed rod 7 in the height direction. The distance from the bottom surface of the uppermost limiting groove 3 to the top surface of the main body 1 is less than the distance from the bottom surface of the fixed rod 7 to the bottom surface of the groove 4. The length of the connecting strap is such that when the fixing rod 7 slides upward and the limiting rod 13 is fixed in the uppermost limiting groove 3, the connecting strap 8 is located above the top surface of the main body 1. This ensures that the connecting strap 8 can restrict the lateral movement of the main body 1 located above. The length from the bottom surface of the lowermost limiting groove 3 to the top surface of the main body 1 is greater than the length of the fixing rod 7. This ensures that when items are placed into the main body 1 or when the top surface of the main body 1 is sealed, the top surface height of the fixing rod 7 is less than the top surface height of the main body 1, and the connecting strap 8 is stored in the storage cavity 5, thus preventing the fixing rod 7 and the connecting strap 8 from affecting the normal use of the main body 1.

[0024] like Figures 1 to 3 As shown, an elastic pad 11 is fixedly connected to the top surface of the main body 1, and an anti-slip pad 12 is fixedly connected to the bottom surface of the main body 1. The anti-slip pad 12 has protrusions that increase the contact area with the elastic pad 11. When the main bodies 1 are stacked on the truck, the anti-slip pad 12 on the bottom surface of the upper main body 1 presses against the elastic pad 11 on the top surface of the lower main body 1, increasing the friction between the upper and lower main bodies 1. The anti-slip pad 12 on the bottom surface of the main body 1 is made of rubber, which can raise the bottom height of the main body 1 and prevent the main body 1 from getting wet when unloading due to water on the bottom surface.

[0025] Working principle:

[0026] When the main body 1 is used for storage, retrieval or sealing operations, the limiting rod 13 on the fixing rod 7 engages with the lowest limiting groove 3. The fixing rod 7 is located below the main body 1, and the connecting strap 8 is wound around the rotating rod 9 and stored in the storage cavity 5.

[0027] When stacking the main body 1, after stacking the main body 1 along the height direction, the anti-slip pad 12 on the bottom surface of the upper main body 1 presses the elastic pad 11 on the top surface of the lower main body 1, separating the limiting rod 13 on the fixing rod 7 from the bottom limiting groove 3. The fixing rod 7 slides upward along the sliding groove 2. The worker pulls the snap connector 10, and the snap connector 10 pulls the connecting belt 8 through the groove 4 from the storage cavity 5, snapping the snap connector 10 into the snap groove 6 on the adjacent fixing rod 7. After the operation is completed, a protective belt is formed between the snap connector 10 and the fixing rod 7, binding the upper main body 1 in the protective belt.

[0028] When the truck accelerates or decelerates during transportation, the upper body 1 is subjected to an inertial force relative to the lower body 1. Smaller inertial forces are offset by the static friction between the anti-slip pad 12 and the elastic pad 11, while larger inertial forces are greater than the static friction between the anti-slip pad 12 and the elastic pad 11. The portion exceeding the static friction between the anti-slip pad 12 and the elastic pad 11 is offset by the connecting belt 8 and the fixing rod 7, achieving relative stillness between the upper body 1 and the lower body 1, thereby preventing relative displacement between the body 1 and causing the body 1 to scatter.

[0029] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
