[0019] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0020] With reference to Figures 1-3 A kind of packaging paper box with moisture-proof function, including box body 1 and box cover 2, box cover 2 is engaged on the upper end of box body 1, the bottom surface of box body 1 four corners is provided with sleeve 6, sleeve 6 one end is set to be open, limiting ring 10 is slidably connected in sleeve 6, the outer wall of limiting ring 10 is conical, air bag 4 is slidably connected in sleeve 6, and is fixedly connected at the end surface of spring pad leg 9, air bag 4 is communicated with multiple sleeve 6 by multiple air pipes 5, and reset mechanism for driving limiting ring 10 reset is installed in sleeve 6;

[0021] Specifically, when placing the box body 1, the air bag 4 is in contact with the ground and compresses air, which is injected into the sleeve 6, so that the leg 9 is extended to effectively isolate the ground moisture.

[0022] The reset mechanism comprises a spring 7 fixedly connected to the top of the sleeve 6, and the other end of the spring 7 is fixedly connected to the end face of the piston 8.

[0023] Specifically, by means of the spring 7, when the box body 1 is carried, the air bag 4 is not in contact with the ground, the spring 7 drives the piston 8 to reset, and then the air in the sleeve 6 flows back to the air bag 4, and the leg 9 is retracted, so as to avoid the clothes from being contaminated during carrying.

[0024] The sleeve 6 is fixedly connected with a limiting ring 10 at the barrel opening, and the inner diameter of the limiting ring 10 is smaller than the outer diameter of the piston 8.

[0025] Specifically, the limiting ring 10 can prevent the piston 8 from separating from the sleeve 6, and ensure the guidance and stability of the piston 8 during movement.

[0026] The outer wall of the piston 8 and the inner wall of the sleeve 6 are circularly arranged, and the outer wall of the piston 8 is in contact with the inner wall of the sleeve 6.

[0027] Specifically, the circular contact design of the piston 8 and the sleeve 6 ensures the air tightness, and prevents the gas leakage from causing the leg 9 to fail to move.

[0028] The height of the air bag 4 is higher than the height of the end face of the leg 9 sliding to the limiting ring 10, and the air pipe 5 is arranged at the top edge of the sleeve 6.

[0029] Specifically, the design of the height of the air bag 4 ensures that when the carton is placed, the air bag 4 can be fully compressed to provide sufficient air pressure to push the piston 8 to move downward, so that the leg 9 is completely extended.

[0030] The outer wall of the box body 1 is provided with two groups of handles 3, and the two groups of handles 3 are symmetrically arranged.

[0031] In the utility model, when the operator places the carton, the self-weight of the box body 1 makes the air bag 4 at the bottom center in contact with the ground and be compressed, the air in the air bag 4 is compressed into the four-corner sleeve 6 through the plurality of air pipes 5, the piston 8 is pushed to move downward against the resistance of the spring 7, the piston 8 drives the leg 9 to extend out of the sleeve 6, a certain gap is formed between the bottom surface of the box body 1 and the ground, the ground moisture is effectively isolated, and the ground moisture is prevented from invading the box body 1 from the bottom.

[0032] When the carton is carried, the operator lifts the box 1 through the symmetrically arranged handle 3, and the air bag 4 is separated from the ground. At this time, the air pressure in the sleeve 6 is reduced, the elastic force of the spring 7 drives the piston 8 to reset, and the supporting leg 9 is retracted into the sleeve 6. At the same time, the air in the sleeve 6 flows back to the air bag 4 through the air pipe 5, and the supporting leg 9 is retracted to avoid the dust adhered when it is in contact with the ground, so as to avoid the pollution of the clothes of the operator during the carrying process.

[0033] The height of the air bag 4 is designed to ensure that the air bag 4 can be fully compressed when the carton is placed, and the sufficient air pressure pushes the piston 8 to move downward, so that the supporting leg 9 is fully extended.

[0034] In summary, the device realizes the automatic extension and retraction function of the supporting leg 9 through the design of the air bag 4 and the sleeve 6, effectively isolates the ground moisture, and avoids the pollution of the clothes by the supporting leg 9 during carrying.

[0035] The above is only the preferred specific implementation manner of the present application, but the protection scope of the present application is not limited to this. Any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
