[0002] A container refers to a basic device mainly composed of a shell for containing materials, and is commonly used as the outer shell of a storage device or other chemical equipment. When using a container, it is necessary to seal the container, which requires an automatic tightening head for an efficiently airtight sealed container. A head refers to a component used to close the end of a container to isolate the internal and external media, also known as an end cover. The heads of cylindrical containers are generally rotating shells, and can be divided into convex, conical, flat and combined shapes according to the shape of the head surface. A convex head refers to a head with a convex outer surface, such as a hemispherical, elliptical, dish-shaped and non-flanged spherical head, etc. Some gas cylinders use a combined bottom head with the convex surface facing inwards, which can not only ensure strength but also meet the requirements of safe use.
