A support piece is provided between the short paperboard and the folding corner of the main box body. A reinforcing strip is provided on the inner wall of the short paperboard, and a movable slot is formed on the opposite side of the two reinforcing strips. A movable strip is connected to the movable slot inside one of the reinforcing strips by a spring, and the end of the movable strip extending out of the reinforcing strip is inserted into the movable slot inside the other reinforcing strip.

[0008] In further embodiments, the outer surfaces of the main box body, short paperboard, and long paperboard are provided with a film layer.

[0009] In further embodiments, the support piece adopts a right-angled triangular structure, one of the right-angled sides of the support piece is fixedly connected to the short paperboard, and the other right-angled side of the support piece is in close contact with the vertical side wall of the main box body.

[0010] In further embodiments, the length direction of the reinforcing strip is parallel to the length direction of the main box body.

[0011] In further embodiments, the upper surfaces of the short paperboard and reinforcing strip are provided with overlapping notches, and the notches are in communication with the inside of the movable slot.

[0012] In further embodiments, the notch is provided with a protrusion therethrough, and the bottom end of the protrusion is fixedly connected with the movable strip.

[0013] In further embodiments, the movable strip is provided with a pyramid head at the end away from the spring.

[0014] Compared with the prior art, the utility model has the beneficial effects that:

[0015] The utility model discloses set up short paperboard when folding and sealing, and the support piece is supported at the corner of short paperboard and main box body, and the two short paperboards are bridged and connected by the reinforcing strip, thereby greatly improving the support strength of short paperboard, effectively reducing the problem that the carton sealing place is easy to collapse, and further guaranteeing the safety of the storage of goods in the carton.
