Technical Field

[0001] The utility model relates to the technical field of environmental protection packaging boxes, in particular to an environment-friendly reinforced packaging box. Background Technique

[0002] With the continuous development of modern industries, the demand for packaging boxes in various industries is increasing. When people transport objects, they pay more attention to the safety and quality of the objects. Therefore, different packages are used for different objects during transportation and storage, and users have put forward higher requirements for their functions. The structure and performance of the packaging boxes are becoming increasingly important.

[0003] Chinese Patent Publication No. CN215554993U proposes an environment-friendly reinforced packaging box, including a box body composed of multiple panels. Reinforcing members are arranged at the four corners of the box body. Each adjacent two of the reinforcing members are connected by reinforcing ribs, and an arc-shaped groove is formed outside the reinforcing member. A rotary pressure relief cylinder is located in the arc-shaped groove and is integrally rotatably connected to the reinforcing member through a limiting member; for the environment-friendly reinforced packaging box proposed by the utility model, while the reinforcing member strengthens the strength of the box body, it has the effect of protecting the four corners of the box body from being damaged; the "X"-shaped reinforcing ribs can provide support for the box body, which is beneficial to improving the stability of the box body and preventing the box body from collapsing; the rotary pressure relief cylinder plays a role in anti-collision, and when the box body collides, due to its own characteristic of being able to rotate under the action of the acting force, it can effectively buffer the collision force, greatly increasing the strength and service life of the box body.

[0004] In the above patent, the reinforcing members are connected to each other through the reinforcing ribs, and the reinforcing members are arranged at the four corners of the box body. Therefore, the side walls of the box body and the reinforcing members are all in mutual contact. When the box body is damaged, it is difficult to replace the box body inside the reinforcing member, and there is even a problem that the reinforcing member cannot be reused again, which is likely to cause waste of resources.

At this time, the first bottom plate 1 and the second bottom plate 2 together form a complete rectangular frame, which is the base part of the packaging box frame;

[0037] Meanwhile, since the positioning rods 5 are fixedly connected to both sides of the top surfaces of the first cross rod 11 and the second cross rod 21, when the first bottom plate 1 and the second bottom plate 2 are fixedly connected to each other, the positions of the four positioning rods 5 correspond to form the column part of the packaging box frame. Through the provision of the support mechanism 7, it is beneficial to support two adjacent positioning rods 5, so that the two positioning rods 5 are balanced with each other through the support mechanism 7, achieving the purpose of improving the stability of the positioning rods 5, that is, improving the stability of the packaging box frame;

[0038] At this time, the first bottom plate 1, the second bottom plate 2 and the positioning rods 5 together form a packaging box frame with an open upper end, so as to be able to support the box body 6 well. And due to the detachable setting of the first bottom plate 1 and the second bottom plate 2, it can effectively achieve the purpose of removing and installing the packaging box frame. When the box body 6 is damaged, the packaging box frame can be disassembled to replace the box body 6, so as to achieve the purpose of enabling the packaging box frame to be reused, and effectively improving the environmental protection of the packaging box.
