Heat insulation connecting structure

The utility model belongs to the field of aviation environmental control and particularly relates to a heat insulation connecting structure, which comprises a plurality of connecting elements 1, a heat insulation plate 2 and a heat insulation plug 3, wherein the connecting elements 1 are embedded into the heat insulation plate 2, then, the head parts of the connecting elements are exposed out, and the heat insulation plug 3 seals the connecting elements 1. The heat insulation connecting structure adopts fastening elements for layered staggered connection. Through adopting the connecting form, the fastening elements do not penetrate through the whole plate layer structure, a cold bridge cannot be formed, the heat insulation effect is ensured, the length of the fastening elements is short, the stress deformation is small, the rigidity is good, the service life is long, the fastening elements are embedded into the heat insulation layer in advance during the installation, then, the layer-by-layer assembly is carr
