These materials are costly themselves, and their production and processing processes do not conform to modern green environmental protection concepts. The assembly or closing process is cumbersome and may require professional tools or personnel, with low efficiency. Although paper coffins are more environmentally friendly and lightweight, the paper coffins in the background art generally have problems such as insufficient structural strength, easy deformation or collapse, especially during loading and handling, and cannot effectively maintain a stable shape, affecting the dignity and safety of use. For existing detachable or assembled paper coffins, the connection methods of their components are often complex and time-consuming, and may require multiple connecting parts or complex operation steps, which are not easy for non-professionals to assemble quickly and correctly, reducing the convenience of use. Summary of the Utility Model

[0003] The technical problem to be solved by the utility model is to provide an assembled corrugated paper coffin to solve the problems existing in the background art.

[0005] The combined paper coffin shell and the paper coffin body are connected through a plug-in structure, thereby realizing the combination between the combined paper coffin shell and the paper coffin body;

[0006] A lining for support is arranged inside the paper coffin body to stabilize the shape of the paper coffin body.

[0007] As a preferred technical solution, the combined paper coffin shell includes an upper seat and a lower seat;

[0008] Fold lines are arranged on both sides of the upper seat and the lower seat, and are bent into a "冂" - shaped structure through the fold lines;

[0009] The bent ends of the upper seat and the lower seat are connected through an "H" - shaped connecting strip, thereby realizing the fixation between the upper seat and the lower seat.

[0010] As a preferred technical solution, the lining includes corners and connecting pieces;

[0011] The corners are arranged around the paper coffin body, and the corners are connected through connecting pieces, thereby realizing the support for the paper coffin body.

[0012] As a preferred technical solution, a sponge pad is also included, which is placed inside the paper coffin body and fixed to the connecting piece on the inner side by adhesive, thereby preventing the sponge pad from loosening.

[0013] As a preferred technical solution, both sides of the paper coffin are provided with inverted trapezoidal clearance grooves to facilitate the movement of the deceased into the paper coffin and prevent damage to the paper coffin.

[0014] As a preferred technical solution, a transparent film is provided on the upper part of the paper coffin shell for viewing the deceased's face.

[0015] As a preferred technical solution, fixing screws are provided at both the top and bottom of the "H"-shaped connecting strip, and the fixing screws pass through the fixing holes of the upper and lower seats, thereby realizing the splicing between the upper and lower seats.

[0016] As a preferred technical solution, the insertion structure includes a guide strip formed on the side of the "H"-shaped connecting strip and a guide groove on the side of the paper coffin body. The combined paper coffin shell and paper coffin body are guided by the guide strip and the guide groove.

[0017] The beneficial effects of this utility model are:

[0018] This utility model features a modular paper coffin shell that is connected to the paper coffin body via an interlocking structure. Combined with creases and "H"-shaped connecting strips, it significantly simplifies the assembly process, allowing for quick assembly without the need for complex tools or specialized skills.

[0019] The lining of this invention is placed inside the paper coffin body, effectively supporting and maintaining the structural shape of the paper coffin body and preventing deformation or collapse. The upper and lower seats are connected by an "H"-shaped connecting strip, and the connection is reinforced with fixing screws passing through fixing holes, ensuring the overall structural strength and stability of the outer shell.
