Set, be provided with set screw in the screwed hole, the lower end of the set screw is provided with bulb, the sphere diameter of the bulb etc.
In the maximum gauge of the bellmouth, the outside of the convex portion is provided with sealing shroud.
Preferably, draw ring is provided with the top of the set screw, the draw ring is integral type knot with the set screw
Structure, it is convenient to extract the present apparatus from vacuum flask bottleneck by setting draw ring.
Preferably, the convex portion and the sealing-plug body are integral type structure, and convex portion and sealing-plug body can be used
Wooden structures, when bulb is embedded into bellmouth, the surface of convex portion is produced to be expanded after slight crack so that sealing shroud is softened, can
More preferably sealed with being formed between bottleneck.
Preferably, the lower end of the sealing-plug body is provided with annular groove, and cooperation insulation is provided with the annular groove
The band of bottle bottleneck, it is glued fixed between the band and the annular groove, after sealing shroud is entered in bottleneck, by
It is sealed in band at position of bottleneck, it is to avoid gas leakage, it is ensured that heat-insulating property.
Preferably, the sealing shroud has an outer surface of taper, that away from the sealing-plug body of the sealing shroud
Hold as small end, the spherical transition in lower surface of the sealing shroud.
The beneficial effects of the utility model are：The present apparatus can be by the backspin of set screw so that bulb and bellmouth
Between be interference fitted so that convex portion expand, band movable sealing sleeve expanded, pass through between sealing shroud and bottleneck closely matching somebody with somebody
Close and complete sealing, it is ensured that heat-insulating property, the structure of the present apparatus is relatively simple, and cost is more cheap, is adapted to promote the use of.
