[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Reference Figure 1-Figure 6 A pressure-resistant environmentally friendly carton includes a box body 1 and a box cover 2. The box cover 2 is rotatably connected to the upper end of the box body 1. Four support rods 3 are placed inside the box body 1. The upper and lower ends of the four support rods 3 are fixedly connected to fan-shaped plates 4. The four support rods 3 support the inner wall of the box body 1 all around. When the box body 1 is squeezed by external force, the box body 1 can be prevented from being deformed and damaged. Both sides of one support rod 3 and one side of the support rods 3 on the adjacent two sides are fixedly connected with a rotating shaft 5. The other end of each rotating shaft 5 is rotatably connected to a first sleeve 6. Each A threaded rod 7 is threadedly connected in each of the first sleeves 6, and the other end of each threaded rod 7 is fixedly connected to the corresponding support rod 3. The first sleeve 6 cooperates with the threaded rod 7 to rotate the first sleeve 6 so that the threaded rod 7 inside it moves. The movement of the threaded rod 7 can adjust the distance between the corresponding two support rods 3. By adjusting the distance between the four support rods 3, it is convenient to open and fix the support rods 3 inside the box body 1 to prevent the support rods 3 from shaking inside the box body 1, and it is also convenient to take and put the whole composed of the four support rods 3;

[0025] Among them, the outer wall of the box body 1 is sleeved with four fixing plates 8, each fixing plate 8 is composed of an L-shaped plate and a rectangular plate, the four L-shaped plates are located around the outer wall of the box body 1, and the four rectangular plates are located at the lower end of the box body 1. Each fixing plate 8 is made of pressure-resistant material, and the four fixing plates 8 protect the outer wall of the box body 1 around to prevent the box body 1 from being damaged by bumps around. Limit rods 9 are inserted into the two side walls of the box body 1, and both ends of the two limit rods 9 pass through the corresponding fixing plates 8 and extend to the outside. Both ends of the two limit rods 9 are sleeved with limit sleeves for limiting the movement of the limit rods 9. Only after the limit sleeves are taken out can the two limit rods 9 be taken out and the fixing plates 8 can be replaced. A plurality of support blocks 10 are arranged at the bottom of the box body 1, and the lower end of each support block 10 is provided with anti-slip grooves, and each anti-slip groove is triangular in shape;

[0026] Among them, the upper end of each support block 10 is fixedly connected to the second sleeve 11, and each second sleeve 11 is slidably connected to a sliding rod 12. The upper end of each sliding rod 12 extends to the outside and is fixedly connected to the lower end of the box body 1. The lower end of each sliding rod 12 is elastically connected to the inner bottom of the second sleeve 11 through a spring 13. With the cooperation of the second sleeve 11 and the sliding rod 12 and the elastic action of the spring 13, the compressive capacity of the box body 1 can be increased. A plurality of plug rods 14 are fixedly connected to the upper end of the box cover 2, and a socket 15 is provided at the lower end of each support block 10 for cooperating with the corresponding plug rod 14. With the cooperation of multiple plug rods 14 and the socket 15, multiple boxes 1 can be stacked together for easy transportation.

[0027] In the utility model, when in use, firstly, four fixing plates 8 are sleeved around the outer wall of the box body 1, and then two limiting rods 9 are respectively plugged into the corresponding two fixing plates 8, and then corresponding limiting sleeves are sleeved on both ends of the two limiting rods 9, so that the limiting of the four fixing plates 8 is completed. By arranging the fixing plates 8 around the outer wall of the box body 1, the pressure resistance of the box body 1 can be improved, and the wear around the outer wall of the box body 1 can be reduced. In addition, the removal and installation of the fixing plates 8 are convenient and simple, and the worn fixing plates 8 are convenient to replace;

[0028] Then, the whole composed of four support rods 3 can be put into the box body 1, and the four first sleeves 6 can be rotated respectively. The four first sleeves 6 can be rotated through the corresponding rotating shafts 5. When the four first sleeves 6 are rotated, the corresponding threaded rods 7 connected with the internal threads can move, and the movement of the threaded rods 7 drives the corresponding support rods 3 to move. By adjusting the spacing between the support rods 3, the four support rods 3 can be spread and fixed around the inner wall of the box body 1. When the box body 1 is subjected to external pressure, the four support rods 3 support it to prevent the box body 1 from being damaged or deformed.

[0029] In addition, when the box 1 is subjected to pressure, through the cooperation of structures such as the support block 10, the first sleeve 6 and the sliding rod 12, under the elastic action of multiple springs 13, the pressure resistance of the box 1 can be increased to protect the integrity of the items inside the box 1, and with the cooperation of multiple insertion rods 14 and multiple sockets 15, multiple boxes 1 can be stacked together for easy transportation.
