To the effect of vacuum heat-insulation.
To achieve the above object, the technical solution that the utility model is taken is：
A kind of stainless-steel vacuum instlated tubular structure, including inner and outer tubes, the both ends of said inner tube are respectively equipped with opening, and two
It is connected between opening with the inside of inner tube, the outer surface of said inner tube is covered with thermal insulation layer, and the outer tube is set in the outer of inner tube
Portion makes between outer tube and inner tube there are vacuum gap, and the inner wall of the outer tube and the inner wall of inner tube are handled by mirror finish,
The both ends of the outer tube are formed slopely vacuum outward respectively, after the outer tube is set in inner tube outside, and pass through vacuum welding
Machine welds outer tube and inner tube in the inside of vacuum, and convex is symmetrically arranged with directly respectively for the both ends cross section of the outer tube
Open position, the straight open position and vacuum are integrally formed design, turn up to form horn-like structure around the edge of the straight open position is past, institute
It states and is respectively provided with more than one annular groove for being used to connect positioning respectively toward sunken inside on outer tube, which is centered around the outer wall of outer tube
On.
Further, there are two the annular groove is arranged altogether, and the both ends of outer tube are distributed in.
Further, the width of the straight open position is 1mm.
Further, the width of the vacuum is 0.3~1.5mm.
Further, the thermal insulation layer is sheathing paper.
Compared with prior art, the utility model has the advantages that：The utility model can according to material property into
The corresponding sub-assembly of row directly imposes vacuum welding integrated molding, by placing metal welding in outer tube vacuum on base material
Agent, so that inner and outer tubes part voluntarily welds, is prevented using capillary principle by the poor thermal conductivity and vacuum heat-insulation of inside and outside material
Heat transfer is equipped with annular groove outside the both ends of the outer tube to achieving the effect that vacuum heat-insulation so that the instlated tubular with
It is more firm after Product Assembly, in addition, the inner wall in outer tube and inner tube does mirror finish processing, to reach more preferably thermal radiation resistant effect
Fruit.

Specific embodiment
To be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, below
In conjunction with specific embodiment, the utility model is further described.
As shown in Figs. 1-2, one of this programme stainless-steel vacuum instlated tubular structure, including inner tube 1 and outer tube 2, it is described
The both ends of inner tube 1 are respectively equipped with opening, are connected between two openings with the inside of inner tube 1, the outer surface of said inner tube 1 be covered with every
Thermosphere 3, the outer tube 2 are set in the outside of inner tube 1, make between outer tube 2 and inner tube 1 there are vacuum gap, the outer tube 2 it is interior
Wall and the inner wall of inner tube 1 are handled by mirror finish, to reach more preferably thermal radiation resistant effect.The both ends of the outer tube 2 point
It is not formed slopely vacuum 4 outward, after the outer tube 2 is set in 1 outside of inner tube, and is picked by vacuum welding in vacuum 4
Outer tube 2 and inner tube 1 are welded in inside, and convex is symmetrically arranged with straight open position 5 respectively for the both ends cross section of the outer tube 2, should
Straight open position 5 and vacuum 4 are integrally formed design, the edge around the straight open position 5 toward turning up to form horn-like structure, it is described outside
