Description
Technical field
The utility model belongs to the technical field of insulating utensils, protects and ties in particular to a kind of double-layer vacuum vessel vacuum hole
Structure.
Background technology
At present, in the market insulating utensils on sale are divided into according to stainless steel inner container vacuum technique tail and anury vacuum technique
Two major classes." having tail vacuum " belongs to traditional technology, uses " pressure sealing technology ", unfortunately this technical measures are micro-
It can not be completely secured in sight closed.Generally, tail welding needs to weld three bottoms：Inner bag bottom, midsole, and outside
Bottom." anury vacuum " be vessel under the environmental condition of vacuum, by computer control complete pumping, soldering and sealing, cool down technique mistake
Journey.
Insulating utensils have been upgraded to " anury vacuum " from " having tail vacuum ", not only make it that its capacity becomes with the product of size
Greatly, and vacuum heat-preserving service life extension.However, the work that the glass basis solder for sealing-in vacuum hole can expand with heat and contract with cold
With also unavoidably being collided with when using in addition, in the course of time, glass basis solder itself can slowly produce crack, and What is more to take off
From matrix.In order to overcome these defects, current people are prevented using the measure of patch adhesive sticker egative film, but adhesive sticker egative film
Also easily come off, protecting effect is not ideal enough.
The content of the invention
The purpose of this utility model seeks to offer one kind and had both been avoided that glass basis solder crack or had come off, and can seal protection
The double-layer vacuum vessel vacuum hole protection structure of vacuum hole.
To achieve the above object, the double-layer vacuum vessel vacuum hole protection structure designed by the utility model, including shell
And inner bag, enclose to form vacuum chamber between the outer wall of the shell and the inwall of inner bag, the outer casing bottom is provided with towards true
The vacuum hole connected with vacuum chamber, the bottom of the holding tank are provided with the raised holding tank of cavity inside, the holding tank
Portion is provided with the annular transitional piece being fixedly connected with its outer wall, and the annular transitional piece bottom is provided with for blocking holding tank
Cover plate.
Further, the holding tank is step trough, and it is from top to bottom divided into the first rank groove, second-order groove, described first
Rank groove is the semi-spherical grooves for accommodating solder, and the second-order groove is the annular groove for installing annular transition plate, the ring
Shape transition plate can be inserted in second-order groove and its inwall spot welding.
Further, the central hole size of the annular transitional piece is more than the opening size of the first rank groove, the annular mistake
The outward flange for crossing piece is bent downwardly the mounting groove that extension formation is used to install cover plate, outer edge and the second-order groove of the mounting groove
Inwall laminating.
Further, the cover plate is circular cover, and the cover plate can be inserted in mounting groove and its inwall circumferentially welds shape
Into sealing fixed structure.
Further, the holding tank and outer casing bottom are formed in one structure.
Yet further, the shell, annular transitional piece and cover plate are stainless steel part.
Further, the solder is glass basis solder.
Compared with prior art, the utility model has the following advantages that：
First, the utility model is combined by annular transitional piece with cover plate carries out sealing protection to holding tank, can be effective
Ground, which avoids the glass basis solder in holding tank from producing crack or come off, causes the problem of vacuum heat-preserving fails, moreover it is possible to prevent insulating utensils
Bottom is hit in use causes vacuum leak.
Second, cover plate of the present utility model is welded after application of vacuum with annular transitional piece, vessel body is not injured, is also kept away
Exempted from because welded cover plate and caused by vacuum leak, be conducive to sealing protection vacuum hole.
Third, the mounting groove inwall of cover plate of the present utility model and annular transitional piece circumferentially welds and forms sealing fixed knot
Structure so that insulating utensils also are difficult to come off under shock, extend service life.
Brief description of the drawings
Fig. 1 is a kind of schematic diagram of double-layer vacuum vessel vacuum hole protection structure；
Mplifying structure schematic diagram in Fig. 1 that Fig. 2 is at I；
Wherein：1- shells, 2- inner bags, 3- vacuum chambers, 4- holding tanks, 5- vacuum holes, 6- annular transitionals piece, 7- cover plates, 8-

Embodiment
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings.
Double-layer vacuum vessel vacuum hole protection structure as illustrated in fig. 1 and 2, including shell 1 and inner bag 2, the outer wall of shell 1
Enclose to form vacuum chamber 3 between the inwall of inner bag 2, the bottom of shell 1 is provided with the holding tank 4 towards the internal protrusion of vacuum chamber 3,
The vacuum hole 5 connected with vacuum chamber 3 is provided with holding tank 4, the bottom of holding tank 4 is provided with what is be fixedly connected with its outer wall
Annular transitional piece 6, the bottom of annular transitional piece 6 is provided with the cover plate 7 for blocking holding tank 4, and holding tank 4 is with the bottom of shell 1
Integrated formed structure, solder 10 is glass basis solder.So, it is combined by annular transitional piece 6 with cover plate 7 and holding tank 4 is carried out
Sealing protection, can be effectively prevented from glass basis solder crack or come off to cause the problem of vacuum heat-preserving fails.
In above-mentioned technical proposal, holding tank 4 is step trough, and it is from top to bottom divided into the first rank groove 8, second-order groove 9, first
