[0002] Corrugated box is a kind of packaging product made of corrugated cardboard through die-cutting, creasing, nailing or gluing. With its superior performance and good processing performance, it has gradually replaced wooden boxes and other transport packaging containers and become the main force of transport packaging. The structure of corrugated box includes face paper, lining paper, core paper and corrugated paper processed into corrugated corrugation, which are formed by bonding. There are many types of corrugated boxes on the market, and most of them need to be customized according to the product size.
[0003] The size of the customized carton is constant, which means that its length and width are also constant. There is a defect that the length and width cannot be adjusted. When the size of the stored items is relatively large, the size of the carton cannot be adjusted within a certain range to complete the loading operation, which affects the convenience of use and brings inconvenience to the user. In view of this, we proposed a corrugated carton with adjustable length and width. Utility Model Content

[0007] Preferably, two mutually symmetrical rope threading holes are provided in the bottom corrugated paperboard, and the rope bodies on both sides of the longitudinal tightening rope pass through the corresponding rope threading holes, so that the longitudinal tightening rope can be put on the carton for binding and fixing operations.
[0008] Preferably, two groups of mutually symmetrical vertical fixing sleeves are fixedly installed on the side of the end cardboard, and the longitudinal tightening rope passes through the vertical fixing sleeve to guide the longitudinal tightening rope so that the position of the longitudinal tightening rope will not deviate.
[0009] Preferably, the longitudinal tightening rope is in a closed ring shape, and the rope bodies on the left and right sides of both ends of the longitudinal tightening rope respectively pass through the two vertical fixing sleeves, so that the longitudinal tightening rope will not fall out directly from the multiple vertical fixing sleeves.
[0010] Preferably, the side corrugated paperboard and the bottom corrugated paperboard have the same path for simultaneous folding and unfolding operations.
[0011] Preferably, two sets of symmetrical transverse fixing sleeves are fixedly installed on the side of the end paperboard, and the transverse tightening rope passes through the corresponding transverse fixing sleeve to achieve a limiting operation on the transverse tightening rope, so that the position of the transverse tightening rope is not easily offset.
[0012] Preferably, an anti-slip block is fixedly mounted at the end of the transverse tightening rope, and the outer diameter of the anti-slip block is larger than the inner diameter of the transverse fixing sleeve, thereby preventing the transverse tightening rope from loosening or falling off.
[0013] Compared with the prior art, the beneficial effects of the utility model are:
[0014] 1. The utility model provides side corrugated cardboard and bottom corrugated cardboard. Since both the side corrugated cardboard and the bottom corrugated cardboard are corrugated, they can be folded or unfolded toward the middle position to adjust the distance between the two end cardboards.

[0025] Specifically, a longitudinal tightening rope 14 is arranged between the two end cardboards 1, and the longitudinal tightening rope 14 is sleeved on the end cardboard 1, the bottom corrugated cardboard 11 and the top covering cardboard 12. The side corrugated cardboard 10 and the end cardboard 1 are sleeved with two upper and lower symmetrical transverse tightening ropes 16 to realize the bundling, limiting and fixing operations of the carton after the size is adjusted.
[0026] In this embodiment, two symmetrical rope threading holes 111 are provided in the bottom corrugated cardboard 11, and the rope bodies on both sides of the longitudinal tightening rope 14 pass through the corresponding rope threading holes 111 to limit the longitudinal tightening rope 14 so that the longitudinal tightening rope 14 will not fall off the carton, and the longitudinal tightening rope 14 can be put on the carton for binding and fixing operations.
