[0020] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.
[0021] Please refer to the appendix. Figures 1-5 The present invention provides a sanitary coffin with a locking device, including an outer coffin 1, a coffin lid 2 slidably connected to the top of the outer coffin 1, a partition 3 horizontally fixed inside the outer coffin 1, an inner coffin 4 connected to the top of the partition 3 through a buffer assembly, the inner coffin 4 being used to place a body, a locking assembly being provided between the outer coffin 1 and the coffin lid 2, and a refrigeration assembly being detachably installed at the bottom inside the outer coffin 1.
[0022] The locking assembly includes several opening slots 5, which are symmetrically opened on both sides of the outer coffin 1. Each opening slot 5 is rotatably connected to a locking rod 6, which is "J" shaped. The top of the coffin lid 2 is provided with several locking slots 7, and the tops of the locking rods 6 are respectively engaged in the locking slots 7. Specifically, when the coffin lid 2 is slidably placed on the outer coffin 1, funeral service personnel can rotate the locking rods 6 to engage in the corresponding locking slots 7, thereby achieving the function of locking the coffin lid 2 and the outer coffin 1, and greatly improving the sealing performance.
[0023] The refrigeration assembly includes a receiving slot 8, which is located at the bottom of the side of the outer coffin 1. A rectangular hole 9 is formed inside the receiving slot 8. The refrigeration assembly also includes a drawer box 10, one end of which passes through the rectangular hole 9, and the bottom of the drawer box 10 slides against the bottom of the inner wall of the outer coffin 1. The other end of the drawer box 10 is located inside the receiving slot 8. The drawer box 10 is located directly below the partition 3. Several ice cubes 11 are placed inside the drawer box 10. Several through holes 12 are evenly distributed on the partition 3. It should be noted that the ice cubes 11 can be prepared by a refrigeration device, such as a refrigerator. Specifically, funeral service personnel can place the prepared ice blocks 11 into the drawer box 10 and then put it into the outer coffin 1. Under the cooling effect of the ice blocks 11, the temperature inside the outer coffin 1 can be effectively reduced through the several through holes 12, thereby effectively refrigerating the remains in the inner coffin 4. Therefore, this sanitary coffin can effectively improve the sealing effect between the coffin lid and the coffin body, and can also effectively refrigerate and store the remains, thus meeting the need to extend the storage time of the remains and providing the bereaved family with more time to arrange funeral matters.
[0024] The buffer assembly includes several spring seats 13, which are fixed to the top of the partition 3 in a rectangular array. Each spring seat 13 has a vertically fixed plastic buffer spring 14 inside. Each plastic buffer spring 14 has a buffer plate 15 fixed to its top, and each buffer plate 15 has a vertically fixed buffer rod 16. The top of each buffer rod 16 vertically penetrates the top of the spring seat 13. The tops of the buffer rods 16 are fixed to the bottom of the inner coffin 4 in a rectangular array. The top of the partition 3 also has several plastic dampers 17 vertically fixed to it. The tops of these plastic dampers 17 are fixed to the bottom of the inner coffin 4. Several limiting slide rails 18 are symmetrically fixed to both sides of the inner wall of the outer coffin 1, and these limiting slide rails 18 are vertically arranged. Several... The sliding blocks 19 have their sides sliding on the surfaces of several limiting rails 18. Specifically, under the combined limiting action of the sliding blocks 19 and the limiting rails 18, the inner coffin 4 can rise and fall stably. Therefore, when the sanitary coffin shakes due to bumps or other reasons during its transport to the crematorium, the inner coffin 4 can compress the plastic buffer spring 14 through the buffer rod 16, causing the plastic buffer spring 14 to undergo elastic deformation and generate buffering force. In conjunction with the use of the plastic damper 17, the body can be effectively buffered and protected, which is conducive to the stable transport of the body to the crematorium. Moreover, both the plastic buffer spring 14 and the plastic damper 17 are made of plastic, making them well-suited for cremation operations.
[0025] The usage process of this utility model is as follows: First, when the coffin lid 2 is slidably placed on the outer coffin 1, the funeral service personnel can rotate and fasten several locking rods 6 into the corresponding locking grooves 7, thereby achieving the function of locking the coffin lid 2 and the outer coffin 1, greatly improving the sealing performance. Then, the funeral service personnel can put the prepared ice blocks 11 into the drawer box 10 and then send it into the outer coffin 1. Under the cooling effect of several ice blocks 11, the temperature inside the outer coffin 1 can be effectively reduced through several through holes 12, thereby effectively refrigerating the remains in the inner coffin 4. Therefore, this sanitary coffin can effectively improve the sealing effect of the coffin lid and the coffin body, and can also effectively refrigerate and store the remains, thereby well meeting the need to extend the storage time of the remains and providing the bereaved family with more time to arrange funeral matters.
[0026] When the sanitary coffin shakes due to bumps and other reasons during its transport to the crematorium, the inner coffin 4 can compress the plastic buffer spring 14 through the buffer rod 16, thereby causing the plastic buffer spring 14 to undergo elastic deformation and generate buffering force. In conjunction with the use of the plastic damper 17, it can effectively buffer and protect the remains, which is conducive to the stable transportation of the remains to the crematorium.
[0027] When the sanitary coffin is cremated with the body, the funeral service personnel can first pull out the drawer box 10, pour out the ice 11 and melted water, and then put the drawer box 10 back into the outer coffin 1 for cremation together. Moreover, the plastic buffer spring 14 and the plastic damper 17 are both made of plastic, which makes them well-suited for cremation operations.
[0028] The above description is merely a preferred embodiment of this utility model. Any person skilled in the art can modify this utility model or modify it into an equivalent technical solution using the technical solution described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solution of this utility model are within the scope of protection claimed by this utility model.
