At the same time, the compressive structure can be disassembled and reused, and most of the compressive structure is installed on the outer surface of the environmentally friendly packaging carton, occupying less internal space of the environmentally friendly packaging carton.

[0045] Second Embodiment

[0046] Please refer to Figures 5-6 , Figure 5 which is a schematic structural diagram of the second embodiment of the compressive environmentally friendly packaging carton provided by the present utility model; Figure 6 which is a schematic structural diagram of the fixing frame provided by the present utility model. Based on the compressive environmentally friendly packaging carton provided in the first embodiment of the present application, the second embodiment of the present application proposes another compressive environmentally friendly packaging carton. The second embodiment is only a preferred manner of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment.

[0047] Specifically, the difference of the compressive environmentally friendly packaging carton provided in the second embodiment of the present application is that a limiting frame 14 is fixedly connected to the top of each of the four first support frames 11, and a magnet 24 is installed on one surface of the inner wall of the limiting frame 14;

[0048] After the magnet 24 is installed, it is flush with the inner surface of the limiting frame 14, and the limiting frame 14 is also L-shaped at 90 degrees.

[0049] A fixing frame 22 is arranged between the four limiting frames 14. Iron sheets 25 are installed at positions close to the corners on the four surfaces of the fixing frame 22, and a cross bar 23 with a pulling opening 21 is installed on the front surface of the inner wall of the fixing frame 22;

[0050] The other end of the cross bar 23 is connected to the back surface of the inner wall of the fixed frame 22. The pull opening 21 is convenient for lifting the fixed frame 22, and the positions of the iron sheet 25 and the magnet 24 correspond to each other.

[0051] Compared with the related art, the compression-resistant environmental protection packaging carton provided by the present utility model has the following beneficial effects:

[0052] In order to increase the supporting force of the environmental protection packaging carton, a limiting frame 14 is respectively installed at the top of each of the four first support frames 11. After the environmental protection packaging carton is sealed, the fixed frame 22 is clamped between the four limiting frames 14, so that the bottom of the fixed frame 22 contacts the top of the environmental protection packaging carton. At the same time, the iron sheet 25 on the outer surface of the fixed frame 22 contacts the magnet 24 inside the limiting frame 14, which can increase the installation stability of the fixed frame 22. Through this structure, the force received by the top of the environmental protection packaging carton can be conducted to the first support frame 11 through the fixed frame 22, reducing the pressure on the environmental protection packaging carton.

[0053] The above are only the embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. All equivalent structural or equivalent process transformations made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, are similarly included in the patent protection scope of the present utility model.
