Vacuum glass is composed of an upper piece of glass, a lower piece of glass and an extraction opening, wherein the upper and the lower pieces of glass are mounted in parallel, and the extraction opening provided with a taper-bored cross section is arranged on the upper piece of glass. A ball-like element is mounted at the bottom of the taper bore of the extraction opening on the upper piece of glass, and glass solder of low-melting point is packed in the taper hole of the extraction opening. The packing structure of single vacuum glass extraction opening is characterized by simple structure, reliable packing and good air tightness, which effectively avoids that the glass solder of low-melting point falls to vacuum cavities to influence the quality of the vacuum glass. The packing structure can realize self-packing of the extraction opening, thereby simplifying fabrication process, increasing service life of the vacuum glass, reducing damage loss of the vacuum glass, and greatly improving the development of vacuum glass.
Description
Technical field
The utility model belongs to the vacuum glass field, especially a kind of encapsulating structure of single vacuum glass bleeding point.
Background technology
Vacuum glass generally is divided into single vacuum glass and many vacuum glass, wherein is made of two-layer sheet glass and forms a vacuum chamber, is called for short single vacuum glass.In the bleeding point packaging process of single vacuum glass, conventional encapsulation is to place extraction pipe between the layer glass edge, utilizes this extraction pipe to connect negative pressure generator and introduces negative pressure, and the scorification extraction pipe is realized the sealing-in of bleeding point then.The defective of this structure is: 1. vacuumize and must carry out in process furnace, and the scorification extraction pipe generally carries out outside stove; 2. can retain the extraction pipe that one section scorification is arranged on the vacuum glass finished product, ten minutes is not attractive in appearance and have gas leakage hidden danger, is not easy to carrying, construction, has hindered the independent use of single vacuum glass; 3. whole complex process, bad operation is an aspect that influences qualification rate.In order to solve this defective, the applicant has invented in vacuum furnace the bleeding point structure that fusion is voluntarily sealed, its mode is at an annular groove of directly making on glass, leave the glass powder with low melting point of ventilating pit in the middle of in this annular groove, loading, utilize glass powder with low melting point fusing back mobile characteristics to seal voluntarily.This mode also has defective, be that glass powder with low melting point is slipped in the vacuum chamber of vacuum glass after fusing inevitably, cause in vacuum chamber retaining glass powder with low melting point is arranged, thereby may stop up the works better that getter hinders getter, influence the quality of vacuum glass.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of simple in structure, to seal resistance to air loss good and do not retain the encapsulating structure of single vacuum glass bleeding point of glass powder with low melting point in the vacuum chamber of sealing part.
The utility model solves its technical problem and is achieved through the following technical solutions:
A kind of encapsulating structure of single vacuum glass bleeding point, vacuum glass is made of last sheet glass, following sheet glass and bleeding point, last sheet glass and the parallel closed assembly of following sheet glass, bleeding point is on last sheet glass, its cross-sectional shape is taper hole or through hole, wherein one spheroid is installed, is packaged with glass powder with low melting point in the bleeding point taper hole above this spheroid in last sheet glass made bleeding point taper hole bottom or through hole bottom.
And, on the following sheet glass in last sheet glass and the formed vacuum chamber of following sheet glass getter is installed.
And described spheroid is the hard spheroid, for its coefficient of linear expansion and akin high melting point glass of last sheet glass or alloy spheroid, is shaped as sphere, ellipse or water droplet shape.
And described getter is installed in the interior made circular groove of following sheet glass of vacuum chamber of corresponding bleeding point taper hole or through hole.
Advantage of the present utility model and beneficial effect are:
1. this single vacuum glass bleeding point sealing structure is to adopt at first to encapsulate a spheroid at sealing part, this seals by the glass powder with low melting point encapsulation again, because the existence of spheroid, make glass powder with low melting point can not be slipped in the vacuum chamber, guaranteed that getter is not covered by glass powder with low melting point, reduced increase, guaranteed the quality level of vacuum glass finished product effectively because of the overheated coefficient of sealing surface generation.
2. this single vacuum glass bleeding point sealing structure adopts the solid encapsulation thing of hard spheroid as bleeding point, this spheroid is material such as the making such as high melting point glass, alloy spheroid of adopting coefficient of linear expansion and vacuum glass basically identical, reliable with the bleeding point sealing-in, improved the total quality level of vacuum glass effectively.
3. this single vacuum glass can be provided with getter, guarantees the steady quality and the work-ing life of vacuum glass.
4. the utility model one-piece construction is simple, the bleeding point encapsulation is reliable, resistance to air loss is good, effectively avoid glass powder with low melting point to be slipped in the vacuum chamber and influenced the quality of vacuum glass, can realize sealing voluntarily of bleeding point, simplify manufacture craft, improve the work-ing life of vacuum glass, reduce the breakage rate of vacuum glass, greatly promoted the vacuum glass industrial expansion.

Embodiment
The utility model is described in further detail below by specific embodiment, and following examples are descriptive, is not determinate, can not limit protection domain of the present utility model with this.
Embodiment 1: a kind of encapsulating structure of single vacuum glass bleeding point, formed vacuum glass is made of last sheet glass 2, following sheet glass 3 and bleeding point 1, last sheet glass and the parallel closed assembly of following sheet glass, between last sheet glass and following sheet glass, leave the gap by uniform upholder, edge between last sheet glass and following sheet glass is equipped with glass powder with low melting point 4, bleeding point is on last sheet glass, operated by rotary motion is in the edge corner positions, its cross-sectional shape is the taper hole that has certain taper, quantity is generally one, also can be provided with a plurality of as required.More than be prior art, do not provide structure formation and label in detail particularly.
Innovative point of the present utility model is: the bleeding point taper hole bottom made at last sheet glass is equipped with a spheroid 6, this spheroid is the hard spheroid, its coefficient of linear expansion and last sheet glass basically identical, the material of spheroid is high melting point glass and alloy spheroid etc., it is shaped as sphere, perhaps structure such as ellipse and water droplet shape is spherical in the present embodiment accompanying drawing.Spheroid is encapsulated in the taper hole bottom, fills in the taper hole above spheroid to be packaged with glass powder with low melting point 5, seals taper hole voluntarily after being implemented in the glass powder with low melting point fusing.
For steady quality and the work-ing life that guarantees vacuum glass, also can put getter 7 on the sheet glass down, this getter generally is seated in the made circular groove of the interior following sheet glass of vacuum chamber, and its position operated by rotary motion is below bleeding point, to make things convenient for the dispensing of getter.
