[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Embodiment 1

[0025] Please refer to Figures 1 to 6, High-load and compression-resistant corrugated cardboard box, including a corrugated cardboard box body 1. At the bottom of the inner wall of the corrugated cardboard box body 1, a first air cushion 2 is fixedly connected. On the top of the first air cushion 2, a pressing plate 3 is fixedly connected. At the four corners of the top of the pressing plate 3, first corner plates 4 are fixedly connected. The side wall of the first corner plate 4 is in contact with the inner wall of the corrugated cardboard box body 1. A second corner plate 5 is slidably connected to the inside of the first corner plate 4. An adjusting mechanism is rotatably connected to one side of the first corner plate 4, and the adjusting mechanism can drive the second corner plate 5 to slide on the top of the first corner plate 4.

[0026] The adjusting mechanism includes a screw sleeve 601. A screw rod 602 is threadedly connected inside the screw sleeve 601. One end of the screw rod 602 is rotatably connected to the second corner plate 5. The inside of the screw sleeve 601 is hollow.

[0027] Inside the screw sleeve 601, a first telescopic plate 603 is provided. One side of the first telescopic plate 603 is fixedly connected to the first corner plate 4. On the other side of the first telescopic plate 603, a telescopic groove 604 is opened. A second telescopic plate 605 is slidably connected inside the telescopic groove 604. One end of the second telescopic plate 605 is fixedly connected to the screw rod 602.

[0028] On the outside of the screw sleeve 601, an adjusting sleeve 7 is fixedly connected. On the outside of the adjusting sleeve 7, a convex block 8 is fixedly connected. The number of convex blocks 8 is several, and several convex blocks 8 are evenly distributed in a ring.

[0029] The working principle of this embodiment: When it is necessary to position the equipment inside the corrugated cardboard box body 1, the equipment is stuffed into the corrugated cardboard box body 1, and then the four corners of the equipment are abutted against the corner plates. The equipment can be positioned through the four corner plates. When it is necessary to replace equipment of different specifications, the user rotates the screw sleeve 601. The screw sleeve 601 drives the screw rod 602 to move away from the screw sleeve 601, so that the screw rod 602 drives the second corner plate 5 to slide inside the first corner plate 4. At this time, the distance between the four second corner plates 5 after sliding is shortened, so equipment of a smaller specification can be adapted. When the screw sleeve 601 is rotated in the reverse direction, the four second corner plates 5 will slide in the reverse direction, thereby increasing the distance between the four second corner plates 5, and equipment of a larger specification can be adapted. By adjusting the position of the second corner plate 5, equipment specifications of different specifications can be adapted, and it can be quickly adjusted according to the existing equipment, improving the practicability of the second corner plate 5. Moreover, the adjustable second corner plate 5 will make the second corner plate 5 fit better with the equipment. During the transportation of the corrugated cardboard box body 1, the equipment will not shake. Cooperating with the first air cushion 2 and the pressing plate 3 at the bottom inside the corrugated cardboard box body 1, it improves the load-bearing and compression resistance of the bottom of the corrugated cardboard box body 1, preventing the equipment from shaking due to the gap between the equipment and the corner plates during transportation, and further damaging the box body and causing damage to the equipment.

[0030] Embodiment Two

[0031] This embodiment is an improvement based on Embodiment 1. Specifically, please refer to Figures 1 to 6 , on one side of the first angle plate 4, a second air cushion 9 is fixedly connected. The top of the first air cushion 2 is communicated with a first connecting pipe 10, and one end of the first connecting pipe 10 is communicated with the second air cushion 9.

[0032] The top of the second air cushion 9 is communicated with a second connecting pipe 11, and one end of the second connecting pipe 11 is communicated with a third air cushion 12.

[0033] By setting the second air cushion 9 and the third air cushion 12, the second air cushion 9 fills the gap between the first angle plate 4 and the second angle plate 5, playing a supporting role for the second angle plate 5, and further improving the positioning effect of the device. The third air cushion 12 fills the gap between the periphery of the device and the corrugated paper box body 1, playing an auxiliary positioning effect on the device, making the corrugated paper box body 1 not easy to shake during transportation. And when transported to a bumpy section, the up-and-down or left-and-right and front-and-back shaking of the device will squeeze the third air cushion 12 on the shaking side. After being squeezed, the third air cushion 12 will transport the original gas inside through the second connecting pipe 11 to the second air cushion 9, strengthening the supporting effect on the second angle plate 5 and preventing the second angle plate 5 from shaking due to the shaking of the device. When the device shakes up and down, the pressing plate 3 at its bottom will press down the first air cushion 2, and the first air cushion 2 will transport the gas inside through the first connecting pipe 10 to the second air cushion 9, and the second air cushion 9 will send it into the third air cushion 12 through the second connecting pipe 11. While strengthening the supporting effect of the second angle plate 5, the supporting effect around the device can also be enhanced, further improving the load-bearing and compressive capacity of the corrugated paper box body 1 for the device.

[0034] On the top of one side of the third air cushion 12, an air injection pipe 13 is communicated. A one-way valve is fixedly installed in the air injection pipe 13, so that the gas can only enter the third air cushion 12 from the air injection pipe 13. On the bottom of one side of the third air cushion 12, an exhaust pipe 14 is communicated.

[0035] The end of the exhaust pipe 14 is communicated with a threaded pipe 15, and a sealing cover 16 is threadedly connected to the outside of the threaded pipe 15.

[0036] By setting the threaded pipe 15 and the sealing cover 16, after rotating the sealing cover 16 to disengage from the outside of the threaded pipe 15, the gas in the first air cushion 2, the second air cushion 9 and the third air cushion 12 will be discharged and reduced through the exhaust pipe 14, adjusting the overall expansion degree. After the adjustment is completed, rotate the sealing cover 16 to seal the threaded pipe 15. When it is necessary to increase the total amount of gas in the first air cushion 2, the second air cushion 9 and the third air cushion 12 to increase its expansion degree and improve the buffering effect, gas can be injected through the air injection pipe 13.
