High vacuum container and adjusting device

A high vacuum container, comprising an inner container body, an outer container body, a first group of supporting devices and a second group of supporting devices, the outer container body being provided with a plurality of openings corresponding to the first group of supporting devices and the second group of supporting devices,

• each group of the supporting devices including four supporting, assemblies around circumference of the high vacuum container, and two said supporting assemblies being disposed at upper portion of the high vacuum container, and the other two said supporting assemblies being disposed at lower portion of the high vacuum container,
• each supporting assembly including a base plate welded at outer surface of the inner container body and a heat insulating pipe extending along, a radial direction of the high vacuum container, one end of the heat insulating pipe abutting against the base plate,
• wherein the four supporting assemblies at the lower portion of the high vacuum container further include four fixing elements respectively, and each fixing element is partly inserted into the outer container body through the opening;
• each fixing element includes a top plate and a bending portion, and the bending portion bends vertically from an edge of the top plate and towards inner part of the high vacuum container, and sleeves onto outside of the heat insulating pipe, and outer surface of the bending portion is welded to the outer container body at the opening,
• wherein each of the two supporting assemblies in each group of the supporting devices at upper portion of the high vacuum container comprises an upper fixing pipe and a cover plate, and the upper fixing pipe is welded to the cover plate, and the cover plate is welded to and conformably covers the outer surface of the outer container body, and the upper fixing pipe goes through the opening of the outer container body and sleeves onto outside of the other end of the heat insulating pipe, and
• wherein four supporting assemblies in the first group of supporting devices are disposed at a rear portion of the high vacuum container, and each of the supporting assemblies in the first group further comprises a lower fixing pipe, which is welded at the base plate and sleeves onto outside of said one end of the corresponding heat insulating pipe.
