[0014] By adopting the above technical solution, a quarter-circular first handle assembly and a second handle assembly are respectively installed on the front top surface and the rear top surface. When the front top surface and the rear top surface are connected, the first handle assembly and the second handle assembly can cooperate to form a semi-circular lifting handle, which makes it convenient for users to lift and move the carton.

[0015] Optionally, both the left and right sides are provided with cardboard layers inside.

[0016] By adopting the above technical solution, cardboard layers are fixedly installed inside the left and right sides of the carton, thereby improving the compressive strength of the left and right sides and thus enhancing the overall structural strength of the carton.

[0017] Optionally, a horizontal through-hole is provided on both the left and right sides, and an insert plate is provided on the cardboard stack, which is inserted into the through-hole.

[0018] By adopting the above technical solution, the cardboard stack is connected to the left and right sides by inserting the insert plate, thereby fixing the cardboard stack to the left and right sides, which greatly improves the structural stability of the left and right sides.

[0019] Optionally, the front, rear, left, and right sides are provided with side holes with lace trim, and a transparent plastic film is provided on the side holes.

[0020] By adopting the above technical solution, side holes are opened on the front, back, left and right sides of the cardboard box, so that users can observe and understand the items stored in the cardboard box through the plastic film without having to open the front and back top, which is convenient and quick.

[0021] Optionally, ligaments are provided at the connection points between the front top surface and the rear top surface and the front side surface and the rear side surface.

[0022] By adopting the above technical solution, ligaments are provided at the front top surface and the rear top surface, as well as at the front side surface and the rear side surface, thereby enhancing the connection strength between the front top surface and the rear top surface, and between the front side surface and the rear side surface.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. By integrally molding the bottom, front, back, left and right sides of the carton, and also integrally molding the top and back sides with the front and back sides, the weak points of traditional nailing or tape joints are eliminated, greatly improving the overall structural strength of the carton. The utilization rate of cardboard is also higher, reducing the waste of scraps when cutting cardboard.

[0025] 2. By installing a quarter-circular ring-shaped first handle assembly and a second handle assembly on the front top surface and the rear top surface respectively, the first handle assembly and the second handle assembly can cooperate to form a semi-circular lifting handle when the front top surface and the rear top surface are connected, making it convenient for users to lift and move the carton.
