[0026] Embodiment 1:

[0027] Please refer to Figures 1-3, A prefabricated coffin using mortise and tenon structure, including the first brown corner tenon 1. There are two groups of the first brown corner tenons 1, and the two groups of the first brown corner tenons 1 are symmetrically arranged. And there is a tenon tongue on the first brown corner tenon 1. One end of each of the two groups of the first brown corner tenons 1 is installed with the second brown corner tenon 4, and there is a mortise on the second brown corner tenon 4. There are multiple groups of slots 16 opened on the two groups of the second brown corner tenons 4, and cross bracing plates 5 are respectively inserted into the multiple groups of slots 16. A first corner brace 2 is fixedly connected to the outer wall on one side of the first brown corner tenon 1, and a second corner brace 3 is fixedly connected to the outer wall on one side of the second brown corner tenon 4. A vertical brown corner tenon 7 that matches the first brown corner tenon 1 and the second brown corner tenon 4 together is installed at the joint of the first brown corner tenon 1 and the second brown corner tenon 4, and there are four groups of the vertical brown corner tenons 7. In this solution, by setting the first corner brace 2 and the second corner brace 3, using the structural stability of the mortise and tenon to add corner braces at the corners of the coffin, the rigidity and torsional resistance of the structure can be enhanced; by setting the cross bracing plates 5, adding cross bracing at the bottom of the coffin can improve the bending resistance of the bottom plate 12 and prevent deformation caused by uneven stress. The combined action of the two improves the bearing capacity of the coffin, reduces the degree of damage to the coffin, and further improves the use effect of the coffin.

[0028] Please refer to Figure 2 , A mortise groove 11 is opened on the first brown corner tenon 1, and a side plate 9 is installed on the mortise groove 11. Cross tenons 10 that match the mortise groove 11 are fixedly connected to the upper and lower surfaces of the side plate 9. By setting the side plate 9, the cross tenons 10, and the mortise groove 11, the installation of the side plate 9 is more accurate, and the accuracy of the structure is improved.

[0029] Please refer to Figures 1-3 , The first corner brace 2 and the second corner brace 3 form a mortise and tenon structure, and the tenon of the first corner brace 2 is adapted to the mortise of the second corner brace 3. By setting the mortise and tenon, it is convenient for installation and disassembly, and the structure is stable, which can increase the rigidity of the structure.

[0030] Please refer to Figure 3 , Transverse chutes 15 are opened on both of the two groups of the second brown corner tenons 4, and a bottom plate 12 is slidably connected between the two groups of the transverse chutes 15, and the bottom surface of the bottom plate 12 abuts against the multiple groups of cross bracing plates 5. By setting the transverse chutes 15, it is convenient for the installation and disassembly of the bottom plate 12. At the same time, setting the bottom plate 12 to abut against the cross bracing plates 5 is to improve the bearing capacity of the bottom plate 12.

[0031] Please refer to Figures 1-3 , Square tenons 13 are fixedly connected to the upper surfaces of the tops of the four groups of the vertical brown corner tenons 7, and a cover plate 8 that is adapted to the square tenons 13 is covered on the four groups of the vertical brown corner tenons 7. By setting the square tenons 13, it is convenient for the covering of the cover plate 8 and improves the rationality of the structure.

[0032] Please refer to Figures 1-3, vertical sliding grooves 14 are provided on the inner walls of the four groups of vertical brown corner tenons 7, and a front board 6 is slidably connected between every two vertical sliding grooves 14. By providing the vertical sliding grooves 14, it is convenient to install and disassemble the front board 6, improving the practicality of the coffin.

[0033] Working principle: During use, the operator holds the first brown corner tenon 1 and inserts the tenon tongue on the first brown corner tenon 1 into the mortise of the second brown corner tenon 4. Through repeated installation, the first brown corner tenon 1 and the second brown corner tenon 4 are spliced into a rectangular frame. Then, the vertical brown corner tenons 7 are installed corresponding to the mortises on the first brown corner tenon 1 and the first corner brace 2. The operator holds the side board 9 and presses the cross tenon 10 below the side board 9 against the mortise groove 11 and presses the side board 9 downwards until it is completely clamped between the two groups of vertical brown corner tenons 7. The front board 6 is inserted along the vertical sliding groove 14 until the front board 6 is completely clamped between the two groups of vertical brown corner tenons 7. The operator holds the cover board 8 and clamps and installs the cover board 8. After the first brown corner tenon 1 and the first corner brace 2 are installed, the tenon head of the first corner brace 2 is inserted into the mortise of the second corner brace 3 to complete the splicing. The corners of the coffin are fixed by the first corner brace 2 and the second corner brace 3. The cross brace board 5 is pushed into the exact position under the bottom board 12 along the horizontal sliding groove 15 to reinforce the bottom board 12, thereby improving the load-bearing capacity of the coffin.

[0034] The above is only the preferred specific embodiment of the present invention; however, the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its improved concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
