[0002] Acetylene, commonly known as wind coal and carbide gas, is the simplest alkyne compound. It is a colorless, highly flammable gas at room temperature. It is mainly used for lighting, welding, rubber synthesis, etc. Acetylene is slightly soluble in water, soluble in ethanol, acetone, etc. It has the risk of violent explosion in liquid and solid state or in gaseous state and under a certain pressure. Acetylene is usually packaged by dissolving it in solvents and porous materials and then loading it into steel cylinders. The storage requirements of acetylene are relatively high. When stored in a low-temperature environment, the tank can only be placed upright, so a storage device is designed to store acetylene.

[0003] For example, the Chinese patent publication number CN217075357U relates to a storage device for acetylene gas production, including a refrigeration seat and an insulation box, the refrigeration seat is fixedly connected to the insulation box, the insulation box is slidably connected to a support frame, one end of the support frame is fixedly connected to a limiting frame, a spring 1 is arranged on the outside of the support frame, the other end of the support frame is fixedly connected to a handle plate, a box cover is hinged on the insulation box, a mounting plate is fixedly connected to the box cover, and a connecting rod is slidably connected to the inside of the mounting plate. The utility model adds structures such as a mounting plate, a connecting rod and a card block to the box cover. After the box cover is closed, the elastic force of the spring 2 can push the card block to slide into the inside of the insulation box to limit the box cover, thereby making the limiting of the box cover more convenient, and when opening, the box cover can be opened by only pulling the pull block.

[0004] After using the storage device for acetylene gas production, it was found that the box cover can be opened by pulling the pull block.
