During the carton processing, usually a cut cardboard is folded into shape, or several cardboards are bonded and spliced together; however, cardboard with high hardness is not easy to bend or is easy to break after bending. Therefore, generally, the cartons formed by bending usually lack hardness. For example, ordinary express delivery boxes; in the field of high-end packaging boxes, cartons with higher hardness are usually used to meet the requirements of environmental protection and non-deformation at the same time; for example, grey board paper cartons are formed by bonding and splicing multiple grey board paper unit cardboards with water-based glue.

This kind of cardboard structure has low hardness, and the packaging carton is easy to be deformed by force; secondly, the existing grey board paper packaging cartons are easy to unhook after being closed, and the closing effect of the cartons is poor. Therefore, a grey board paper packaging carton is proposed for the above problems. Content of the Utility Model

[0028] This application embodiment discloses a grey board paper packaging carton. Referring to Figure 1 and Figure 6 , a grey board paper packaging carton includes a box body 1; a box cover structure 2 is arranged at the port of the box body 1, and a clamping structure 3 is installed on the left and right side walls of the box cover structure 2;

[0029] The box cover structure 2 includes a first grey board paper layer 201. A triangular structure layer 202 is installed at the bottom of the first grey board paper layer 201. A second grey board paper 203 is installed at the bottom of the triangular structure layer 202. The triangular structure layer 202 is formed by splicing a plurality of right triangle frames. The triangular structure has extremely strong stability, so that the pressure-bearing strength of the triangular structure layer 202 is greater than that of the traditional wavy sandwich layer, solving the problem that the cardboard sandwich of the existing grey board paper packaging carton is mostly a wavy structure, the hardness of this kind of cardboard structure is low, and the packaging carton is easily deformed by force, improving the strength of the packaging carton and making the carton have better pressure resistance ability;

[0030] The snap - fit structure 3 includes a plug board 301 and a limit box 302. A pressing plate 303 is installed on the side wall of the plug board 301. A first connecting plate 304 is installed on the side wall of the pressing plate 303. An elastic member 305 is installed on the side wall of the first connecting plate 304. The other end of the elastic member 305 is provided with a second connecting plate 306. A slot 307 is opened on the limit box 302 corresponding to the pressing plate 303. The position of the plug board 301 is locked by using the pressing plate 303 to hold the slot 307, avoiding the phenomenon that the plug board 301 will become disengaged in the limit box 302, increasing the connection stability between the plug board 301 and the limit box 302, solving the problem that the existing grey board paper packaging carton is prone to becoming disengaged after closing, and improving the closing effect of the carton;

[0031] Refer to Figure 3 and Figure 4 , the bottom of the first grey board paper layer 201 is connected to the port of the box body 1; the triangular structure layer 202 is formed by splicing a number of right - angled triangle frames, and the triangular structure layer 202 is made of grey board paper;

[0032] Among them, since the triangular structure layer 202 is formed by splicing a number of right - angled triangle frames, the triangular structure has good stability, thus improving the hardness of the carton and increasing the anti - pressure ability of the carton;

[0033] Refer to Figure 1 and Figure 5 , the box body 1 and the box cover structure 2 have the same structure, and the plug board 301 is arranged in a semi - circular structure; the plug board 301 is connected to the side wall of the box cover structure 2, and the side wall of the limit box 302 is connected to the side wall of the box body 1;

[0034] Among them, the plug board 301 is arranged in a semi - circular structure, making it more convenient for the plug board 301 to be inserted into the limit box 302, providing convenience for the closing of the carton;

[0035] Refer to Figure 5 and Figure 6 , the side wall of the second connecting plate 306 is connected to the side wall of the plug board 301; the elastic member 305 is formed by splicing a number of diamond frames, and the elastic member 305 is made of paper; the pressing plate 303 and the slot 307 are set to be adapted to each other;

[0036] Among them, the elastic member 305 is formed by splicing a number of diamond frames and is made of paper, enabling the elastic member 305 to have elastic properties and realizing the opening and closing functions of the carton;

[0037] Working principle: The triangular structure layer 202 is formed by splicing a number of right-angled triangle frames. The triangular structure has extremely strong stability. The first grey cardboard layer 201 is conveyed under force to the triangular structure layer 202. The structure of the triangular structure layer 202 is stable and not prone to deformation, thereby increasing the compressive strength of the packaging carton. By setting the box cover structure 2, it solves the problem that the cardboard interlayer of the existing grey cardboard packaging carton is mostly in a wavy structure, and the hardness of this cardboard structure is low, and the packaging carton is prone to deformation under force, improving the strength of the packaging carton and making the use effect of the carton better; when the insertion plate 301 drives the pressing plate 303 into the interior of the limit box 302, the side wall of the pressing plate 303 slides on the inner cavity side wall of the limit box 302, and the front end of the pressing plate 303 is stressed. Through the transmission of the first connecting plate 304, the elastic member 305 is squeezed and deformed. When the front end of the pressing plate 303 passes through the inner cavity side wall of the limit box 302 and enters the card slot 307, under the action of the reset rebound force of the elastic member 305, the front end of the pressing plate 303 is stuck in the card slot 307, thereby locking the position of the insertion plate 301 and avoiding the phenomenon that the insertion plate 301 will become disengaged in the limit box 302, increasing the connection stability between the insertion plate 301 and the limit box 302. By setting the clamping structure 3, it solves the problem that the existing grey cardboard packaging carton is prone to becoming disengaged after being closed, improving the closing effect of the carton.

Those skilled in the art of this industry should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed.
