Description

Full-paper annular cavity buffer lining assembly and packaging box thereof Technical Field The utility model relates to the technical field of corrugated packaging, in particular to an all-paper annular cavity buffer lining assembly and a packaging box thereof. Background The electronic products use materials such as EPS (polystyrene foam plastic) as a packaging buffer lining, mainly because these materials have good buffer performance and lower cost, and therefore EPS is widely used in the packaging of high-end electronic products, such as notebook computers and tablet computers, due to its light weight, high strength and excellent buffer performance. Along with the improvement of global environmental protection consciousness and the formulation of green trade barriers by various countries, traditional nondegradable materials such as EPS and the like are gradually replaced by environment-friendly materials such as corrugated boards and the like. The corrugated board as a green packaging material has the advantages of low cost, convenient material taking, mature production process, good processing performance and the like, and is easy to recycle. In addition, the corrugated board has the characteristics of wide applicable temperature range and the like, and can meet the requirements of different electronic product packages. Because the buffering performance and the bearing performance of the sheet corrugated board are relatively weak, and particularly the sheet corrugated board can not completely replace traditional materials such as EPS (expandable polystyrene) and the like under high impact conditions, the sheet corrugated board needs to be formed into a buffering lining through special design of a folding corrugated board structure, so that the buffering and bearing effects of the sheet corrugated board are improved, and the product is better protected. However, the folded structure is large in size after being formed, the folded structure is required to be split into different components for storage and transportation, and the components formed in the storage and transportation process cannot be folded and compressed again, so that a large storage and transportation space is required, the storage and transportation cost is obviously increased, and the components are assembled during use, so that the use efficiency is low. Therefore, there is a need to develop a cushioning liner that combines cushioning properties of a folded structure with reduced storage and transportation space after molding. Disclosure of Invention The utility model aims to provide an all-paper annular buffer lining assembly and a packing box with the all-paper annular buffer lining, so as to solve the problems in the prior art. In order to solve the technical problems, the technical scheme provided by the utility model is as follows: The utility model provides a full paper ring chamber buffering inside lining, full paper ring chamber buffering inside lining is formed by integrative folding of a slice corrugated container board, and the three-dimensional full paper ring chamber buffering inside lining after the shaping can fold into the slice structure again, full paper ring chamber buffering inside lining includes ring chamber inner wall, ring chamber outer wall, collet and presss from both sides ring chamber inner wall with elastic buffer structure between the ring chamber outer wall, ring chamber inner wall with ring chamber outer wall passes through the connection piece and connects, elastic buffer structure with the collet is by ring chamber outer wall outwards extends, folds to form, and all has M style of calligraphy buffer structure. Further, the inner wall of the annular cavity and the outer wall of the annular cavity comprise four folded sheets which are connected in sequence. Further, one side of the inner wall of the annular cavity extends outwards to form a self-locking bottom. Further, the elastic buffer structure and the M-shaped buffer structure of the bottom support are also provided with a square buffer structure. The invention also discloses a packing box with the full-paper annular buffer lining, wherein at least one pair of full-paper annular buffer lining is oppositely arranged in the packing box, and two ends of a packaged article are respectively embedded and fixed in the full-paper annular buffer lining. The beneficial effects of the utility model are as follows: According to the utility model, the elastic buffer structure which is clamped between the inner wall of the annular cavity and the outer wall of the annular cavity and is formed by the M-shaped buffer structure and the mouth-shaped buffer structure is used for forming the buffer annular cavity, the packaged product is placed in the space formed by the inner wall of the annular cavity, when the product is impacted, the M-shaped structure similar to a spring can effectively release the impact force and has rebound resilience, the mouth-shaped structure
