Description
Technical field
The utility model belongs to the vacuum glass field, especially a kind of sealing protection structure of vacuum glass exhaust tube mouth.
Background technology
Planar vacuum glass develops the history in existing 10 years at home, and is used widely.Vacuum glass constitutes to triplex glass by two usually, is provided with cavity between the adjacent glass, and the edge is provided with edge sealing between adjacent glass, and cavity forms the vacuum interlayer after being pumped into vacuum.In the process of making vacuum glass, usually a bleeding point is offered at the edge between adjacent two sheet glass in cavity, extraction pipe is extend in the cavity from bleeding point, connecting extraction pipe by vacuum unit will be evacuated in the cavity, and the glass filler sealing of sealing of sintering extraction pipe and fusion bleeding point periphery promptly realizes the sealing of vacuum glass then.When extraction pipe and bleeding point are sealed, usually there are two problems: 1, can stay next tail after the sealing of extraction pipe sintering, cause vacuum leak for fear of the extraction pipe damage, usually adopt tin hat to be covered dress, but because this extraction pipe retention is a projection, in any case the lid dress all is a dangerous hidden danger; 2, bleeding point owing to gravity or flow problem, often becomes an important hidden danger of vacuum leak in its peripheral glass filler melting process; Moreover owing to exist expansion coefficient difference inevitably between glass filler and extraction pipe and the upper and lower sheet glass, the sealing of bleeding point periphery is an importance that influences the vacuum glass quality always.
By retrieval, two pieces of close patent documentations have been found.CN201016109 discloses a kind of energy and will vacuumize envelope mouth that the back forms and be hidden in vacuum glass in the bead layer, constitute by layer glass at least, the edge of adjacent glass is provided with bead layer, cavity between the adjacent glass forms the vacuum interlayer, the edge that constitutes a side glass of vacuum interlayer is provided with the arrangement breach, settle in the breach and be provided with extraction pipe, extraction pipe communicates with the vacuum interlayer, the envelope mouth of extraction pipe is sealed in the bead layer.CN201158615 discloses a kind of no vertebra tail planar vacuum glass, comprise two-layer float glass process or low emissivity glass, it between two-layer float glass process or low emissivity glass vacuum layer, being provided with barometric point in vacuum layer between two-layer float glass process or the low emissivity glass supports, on two-layer float glass process or edge, low emissivity glass surrounding, be provided with the tackiness agent bead layer, the outside surface of two-layer float glass process or low emissivity glass is slick surface, compares with other vertebra tail ridge vacuum glass and has reduced production link; Appearance does not have ridge, and product is more attractive in appearance; Help installation, production line is short out, facility investment is little, power consumption less, production cost is low, helps the vacuum glass penetration and promotion, reaches the purpose that building energy conservation reduces discharging.
Above-mentioned two pieces of documents though extraction pipe has been carried out certain improvement, from the technology contents of its record, all are that glass itself is widened, and practical application effect is relatively poor; And, all can't solve the gas leakage potential problem of bleeding point.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of extraction pipe design science, protection is effective and to the sealing protection structure of mounting groove reliable sealing vacuum glass exhaust tube mouth.
The utility model solves its technical problem and is achieved through the following technical solutions:
A kind of sealing protection structure of vacuum glass exhaust tube mouth, the mounting groove that comprises extraction pipe, extraction pipe, mounting groove is the corresponding groove of making between last sheet glass and the substrate glass, setting-in extend into the extraction pipe of vacuum glass cavity on bleeding point, in the mounting groove of extraction pipe periphery, put packing seal, it is characterized in that: be shaped on a through hole on the sheet glass on the corresponding extraction pipe position, the extraction pipe periphery between sheet glass on the lead to the hole site and substrate glass forms sealing ply.
And the described upward made through hole of sheet glass is one, perhaps the through hole of a plurality of random geometries.
And described vacuum glass is a dual-layer vacuum glass, perhaps double-deck above vacuum glass.
And described extraction pipe is arranged on the side of vacuum glass, perhaps is arranged on the bight of vacuum glass, sheet glass and substrate glass position outsourcing one wall supporting on this extraction pipe and lead to the hole site.
Advantage of the present utility model and beneficial effect are:
1, the utility model has mounting groove on two sheet glass of vacuum glass bleeding point, and in extraction pipe is encapsulated in, importantly: can make the Glass tubing length behind the sealed knot be no more than the sheet glass edge, in addition wall supporting is realized the purpose of the flat envelope of anury again.
2, the utility model is provided with a through hole above the extraction pipe mounting groove, can mend packing packing material to the bleeding point of extraction pipe periphery by this through hole, solve lock packing owing to gravity or the mobile hidden danger that causes vacuum leak, guaranteed the quality level of vacuum glass.
3, the utility model is simple in structure, and design science has ideally solved sealing, the protection question of vacuum glass in bleeding point and extraction pipe existence, for the quality of production that improves the vacuum glass industry contributes.
Description of drawings
Fig. 1 is the installation site synoptic diagram of the utility model extraction pipe and bleeding point;
Fig. 2 is the side extraction pipe of Fig. 1 and the structure enlarged diagram (partly cuing open figure) of bleeding point;
Fig. 3 is that the A-A of Fig. 2 is to cross-sectional view.
Embodiment
The utility model is described in further detail by specific embodiment below in conjunction with accompanying drawing, and following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
Constitute vacuum glass between sheet glass 1 and the substrate glass 2 faulting of slab ends 3 at edge be the edge sealing of vacuum glass (also can adopt down the edging structure of miter angle).Sealing protective device 4 is arranged on the side of vacuum glass in accompanying drawing 1, and sealing protective device 5 is arranged on the corner positions of vacuum glass.This sealing protective device can be provided with one, also can be provided with a plurality of as required.
