AI Technical Summary
Existing coffins lack sufficient sealing, durability, moisture-proof insulation, and warmth, and are also costly.
Using high-strength foam plastic as the main material, combined with a steel frame, the coffin lid and coffin box are designed with a connection structure. The sealing ring and inclined wall are used in conjunction with fastening bolts to achieve sealing and stability, thereby reducing costs.
This improved the coffin's sealing, durability, and moisture and heat insulation properties, while also reducing costs.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of funeral supplies technology, specifically to a coffin with high environmental protection and stability. Background Technology
[0002] A coffin, used to protect the body, delay decomposition, and provide space for funeral rites, is also called a longevity coffin, fang, shoufang, laofang, sikuaiban, or shidakuai. It is a container for the human body, typically used in funerals. The coffin holding the body is called a spirit coffin. Coffins can be made of various materials, most commonly wood, such as cypress, pine, nanmu, willow, and paulownia. Coffins are also made of copper, stone, and other materials.
[0003] In the process of realizing this utility model, the inventor discovered the following problems with the existing technology: In the past, the coffins commonly used for burial were mainly made of a few types of wood, which were not good in terms of sealing, durability, moisture protection, heat insulation, and warmth, and were also expensive. Utility Model Content
[0004] In view of the shortcomings of existing technologies, this utility model provides an environmentally friendly and highly stable coffin, which solves the problems that existing coffins are mainly made of a few types of wood, and are not good in terms of sealing, durability, moisture protection, heat insulation, and warmth, and are also expensive.
[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: an environmentally friendly and highly stable coffin, including a coffin box, a coffin lid placed on the coffin box, a sealing ring provided around the lower wall of the coffin lid, a connecting ring provided inside the sealing ring, the wall of the connecting ring having an inclined angle, an inclined wall provided on the inner wall of the coffin box, the inclined wall cooperating with the connecting ring, and threaded grooves provided on the side wall of the coffin box and around the coffin lid, with fastening bolts threaded into the threaded grooves.
[0006] Preferably, the coffin lid and the coffin box are made primarily of high-strength foam plastic.
[0007] Preferably, the coffin lid and the frame inside the coffin box are made of steel.
[0008] Beneficial effects
[0009] This utility model provides an environmentally friendly and highly stable coffin. The coffin design features a highly environmentally friendly structure where the coffin lid and coffin box work together. The inclined slope of the side wall of the connecting ring matches the inclined wall, resulting in a high degree of sealing when they are attached together. A sealing ring further enhances the seal, and the overall stability is strengthened by tightening bolts. The main materials used in this application are steel for the frame and high-density foam plastic for the main body, molded in one piece to form the main coffin. Compared to traditional coffins, this application offers significant improvements in sealing, durability, moisture resistance, heat insulation, and warmth, while also being less expensive than pure wooden coffins, making it suitable for widespread use.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0014] Please see Figure 1-2 This utility model provides a technical solution: an environmentally friendly and highly stable coffin, including a coffin box 2, a coffin lid 1 placed on the coffin box 2, a sealing ring 4 around the lower wall of the coffin lid 1, a connecting ring 5 inside the sealing ring 4, the wall of the connecting ring 5 having an inclined angle, an inclined wall 6 on the inner wall of the coffin box 2, the inclined wall 6 cooperating with the connecting ring 5, and threaded grooves on the side wall of the coffin box 2 and around the coffin lid 1, with fastening bolts 3 threadedly connected in the threaded grooves.
[0015] In this embodiment, the coffin lid 1 and the coffin box 2 are mainly made of high-strength foam plastic.
[0016] In this embodiment, the coffin lid 1 and the frame inside the coffin box 2 are made of steel.
[0017] Its detailed connection method is a well-known technology in this field. The following mainly introduces the working principle and process, and the specific work is as follows.
[0018] Example 1: This device uses a coffin lid 1 and a coffin box 2 for assembly. The slope of the side wall of the connecting ring 5 matches the slope of the inclined wall 6, resulting in a high degree of sealing when they are attached together. The sealing ring 4 is used to enhance the seal. Fastening bolts 3 are threaded into the threaded grooves inside the coffin lid 1 and coffin box 2 to strengthen the overall stability. The main materials used in this application are steel for the frame and high-density foam plastic for the main body, molded in one piece to form the main coffin. The fastening bolts 3 are used for fixing and connecting, and their appearance can be customized according to local customs and preferences.
[0019] Example 2: In this application, a skeleton may not be used. Based on Example 1, the coffin lid 1 and coffin box 2 need to be made thicker, which reduces the cost.
[0020] It should be noted that in this paper, relational terms such as first and second are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
