Abstract
The invention relates to a melt-sealing structure of vacuum glass exhaust holes in a vacuum state, which comprises upper glass, substrate glass, a support, edge-sealing low-melting-point glass powder and the exhaust holes. The structure is characterized in that the exhaust holes are preserved at any corners of the upper glass, a hindrance ring larger than the upper glass exhaust holes in diameter is arranged on the substrate glass at each exhaust hole of the upper glass, exhaust glass powder is filled in the upper glass exhaust holes, and the exhaust hole glass powder is heated to melt to seal the exhaust holes. The upper glass is provided with the exhaust holes, the hindrance rings are arranged on the substrate glass corresponding to the exhaust holes, the glass powder in the exhaust holes cannot flow freely during melting by the aid of the hindrance rings, sealing of the exhaust holes is facilitated, air leakage is avoided, and production efficiency and quality of vacuum glass are improved.
Description
Technical field
The invention belongs to the vacuum glass field, relate to the sealing by fusing structure of a kind of vacuum glass aspirating hole under vacuum state.
Background technology
At present, aspirating hole is bled at side or four jiaos generally between last sheet glass and base plate glass.But the unsurmountable shortcoming of this method is to fracture extraction pipe easily and cause gas leakage, Glass tubing to increase vapour lock, the influence quality of bleeding, thus influence the quality of vacuum glass.For this reason, the research of many producers is beaten aspirating hole on last sheet glass, and method for sealing in vacuum oven is to avoid occurring problems such as extraction pipe fracture, minimizing vapour lock.The gas leakage or influence attractive in appearance but glass powder with low melting point can cause trickling in the time of heat fused in vacuum chamber.
Through retrieval, do not find the technical scheme that addresses the above problem as yet.
Summary of the invention
The objective of the invention is to overcome the deficiency of prior art, the sealing by fusing structure of a kind of vacuum glass aspirating hole under vacuum state is provided.
The present invention solves its technical problem and realizes through following technical scheme:
The sealing by fusing structure of a kind of vacuum glass aspirating hole under vacuum state; Comprise sheet glass, base plate glass, upholder, edge sealing glass powder with low melting point and aspirating hole; It is characterized in that: at the prefabricated aspirating hole of any corner location of last sheet glass; Corresponding on each the base plate glass of the aspirating hole position of sheet glass be provided with diameter greater than on the obstruction ring of sheet glass aspirating hole diameter; Be filled with aspirating hole glass powder in the last sheet glass aspirating hole, this aspirating hole glass powder is heated fusing back sealing aspirating hole under vacuum state, and this vacuum tightness is 1 * 10
-1Pa-1 * 10
-5Pa.
And the made obstruction ring of said base plate glass is at least one annular recesses that grinds out with hollow drill, or prior prefabricated annular or hollow high temperature resistant inorganic gasket rings or the wire coil of quadrate, and it highly is lower than vacuum glass supporter height.
And said aspirating hole glass powder is lower melting point crystallization or non-crystalline glass powder, or glass powder with low melting point and inorganic globular mixture, and inorganic spherule is within the parcel of glass powder.
Advantage of the present invention and beneficial effect are:
1, the present invention makes aspirating hole on last sheet glass; Hindering ring to being provided with on should the base plate glass of aspirating hole; Hinder ring through this, can guarantee glass powder nonvoluntary the flowing when fusing in aspirating hole, help sealing aspirating hole; Avoid the generation of gas leak phenomenon, improve the production efficiency and the quality of vacuum glass.
2, the glass powder of the present invention in aspirating hole can adopt various ways, and shape and size after the glass powder fusing can control, and effectively improves the sealing effectiveness of aspirating hole.

Embodiment
Through specific embodiment the present invention is made further detailed description below, following examples are descriptive, are not determinate, can not limit protection scope of the present invention with this.
The sealing by fusing structure of a kind of vacuum glass aspirating hole under vacuum state; Comprise sheet glass 2, base plate glass 1, upholder 7, edge sealing glass powder with low melting point 4 and aspirating hole 3, its ME is: cut-parts, punch, develop a film, lay supporter, close sheet, lay glass powder with low melting point, whole technological processs such as normal pressure-sintered stove edge sealing, vacuum-pumping and sealing.Innovative point of the present invention relates to the sealed structure of aspirating hole, is specially:
Be total to a prefabricated 1-6 aspirating hole at any corner location of last sheet glass, the present embodiment accompanying drawing is four aspirating holes, and is prepared in four corners position, in aspirating hole, places encapsulation aspirating hole glass powder.Corresponding on each the base plate glass of the aspirating hole position of sheet glass be provided with a diameter greater than on the obstruction ring 6 of sheet glass aspirating hole diameter; Be filled with aspirating hole glass powder 5 in the last sheet glass aspirating hole, aspirating hole glass powder seals aspirating hole after heat fused.
The made obstruction ring of aforesaid substrate glass can be at least one annular recesses that grinds out with hollow drill, like Fig. 3, is shown as in the present embodiment accompanying drawing together; Annular that also can be in advance prefabricated, high temperature resistant inorganic gasket rings or wire coil such as square, like Fig. 2, its height can not be higher than vacuum glass supporter height, arbitrarily flowing during with the fusing of interception glass powder with low melting point.
Above-mentioned aspirating hole glass powder is lower melting point crystallization or non-crystalline glass powder; Also can be glass powder with low melting point and inorganic spherical 8 mixture, inorganic spherule be within the parcel of glass powder, and the size of inorganic spherule and quantity can be decided according to the diameter and the degree of depth of aspirating hole; Be advisable not to be higher than glass table plane; Being a plurality of inorganic spherules among Fig. 4 wherein, be an inorganic spherule among Fig. 5, and its aspirating hole is processed taper.
The step that the present invention is not described in detail is a prior art.
