Background technology
Vacuum glass is generally made up of two or polylith sheet glass plate, the sealing of sheet glass surrounding, and centre is provided with small upholder, makes the air pressure in space between adjacent two sheet glass lower than normal atmosphere by bleeding.Because the convection action of gas reduces, therefore, vacuum glass has the effect of good heat insulation, sound insulation.
And the method for bleeding probably has two kinds, a kind ofly in vacuum chamber, carry out while being the sealing-in of two glass sheets, along with completing of sealing-in, the gap self-assembling formation vacuum of institute's sealing-in between two glass sheets; Another kind is first by compound two glass sheets, and sheet glass periphery is carried out to sealing-in, then by prefabricated bleeding point on a sheet glass wherein, the space of sealing between sheet glass is vacuumized, and finish rear enclosed bleeding point bleeding, complete the making of vacuum glass.For the second vacuum glass, because sealing bleeding point is the final tache of making vacuum glass, whether the sealing of bleeding point is reliable, and whether enclosed construction is simple, firm, is directly connected to the quality of vacuum glass and the work-ing life of vacuum glass.
Utility model content
For addressing the above problem, the purpose of this utility model is to provide a kind of sealing structure of vacuum glass pumping hole.
For achieving the above object, the sealing structure of a kind of vacuum glass pumping hole of the utility model comprises: two glass sheets of parallel placement, in the middle of two glass sheets, be provided with upholder, peripheral sealing, describedly wherein in a glass sheets, be provided with bleeding point, the opening part of described bleeding point is provided with the sealing member of being made up of low melting glass of the described bleeding point of sealing after fusing.
Further, described bleeding point is circular straight hole or conical bore.
Further, described bleeding point is circular straight hole, and its opening part is provided with concentric counterbore or conical bore.
Further, described bleeding point is circular straight hole, and the diameter of described sealing member is slightly less than circular straight hole diameter; And the radius of described sealing member is greater than the spacing between described two glass sheets.
Further, the shape of described sealing member is spheroid, spheroid, cone or other shapes.
Further, in described sealing member, be also wrapped in the occluding body that occluding body that a softening temperature glass close with described sheet glass makes or high melting point metal materials are made.
Further, described high melting point metal materials is steel and alloy, aluminium alloy, copper alloy or kovar alloy.
Further, described occluding body can be spheroid or polyhedron, and its external diameter is more than or equal to the diameter of bleeding point.
After having bled, by local heating, sealing member is melted, the sealing member after fusing directly seals up bleeding point, and this sealing structure is simple, reliable, and easy handling is realized, and the efficiency of sealing-in is simultaneously higher.

Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described.
embodiment 1
As Figure 1-3, the sealing structure of a kind of vacuum glass pumping hole of the utility model comprises: upper glass sheets 20 and lower glass sheets 10; Upper glass sheets 20 and lower glass sheets parallel stacking Shang Xia 10, centre is provided with upholder 11, and periphery 12 seals; In upper glass sheets 20, be provided with bleeding point 30, bleeding point is circular straight hole, the sealing member 36 that after the opening part of bleeding point 30 is provided with and melts, the glass by low melting point of the bleeding point of sealing bleeding point 30 is made.
In order to place better sealing member 36, the opening part of bleeding point 30 is provided with the conical bore concentric with bleeding point.The size of the degree of depth of conical bore and openings of sizes and spheroid 36 adapts.Sealing member be shaped as spheroid, spheroid, cone or other shapes, the external diameter of sealing member be bleeding point diameter 1.5-2.5 doubly.
In addition, as shown in Figure 6, the opening part of bleeding point 30a also can facilitate spheroid to place by counterbore is set.Or as shown in Figure 7, the form of bleeding point 30b can also be conical bore, the diameter of sealing member is less than the maximum diameter of conical bore, and is greater than the minimum diameter of conical bore.Or as shown in Figure 8, bleeding point 30c is circular straight hole, the diameter of sealing member is slightly less than circular straight hole diameter, and the radius of sealing member is greater than the spacing between described two glass sheets.
In the time producing vacuum glass, upper and lower two glass sheets are stacked together, and wherein in a glass sheets, bleeding point are set, on bleeding point, place sealing member 36, after surrounding sealing-in completes and vacuumizes, by sealing member 36, by heat fused, 36 of sealing members after fusing are by bleeding point shutoff.
Compared with prior art, the more simple and convenient operation of sealing structure of the present utility model, has improved production efficiency greatly.
embodiment 2
The present embodiment is substantially the same manner as Example 1, and difference is:
As shown in Figure 4, close bleeding point is arranged in lower glass sheets, is placed with sealing member 37 on bleeding point.
As shown in Figure 5, in the sealing member 37 of being made by low melting glass, be also wrapped in an occluding body 37b who is made by high melting point glass or metallic substance., occluding body 37b is outer is wrapped in by low melting glass 37a.Described high melting point metal materials is steel and alloy, aluminium alloy, copper alloy or kovar alloy etc.
Occluding body 37b can be spherical or polyhedron; The external diameter of occluding body is more than or equal to the diameter of bleeding point, and the external diameter of preferred occluding body is 1-1.5 times of bleeding point diameter.
When sealing bleeding point, by heating, by low melting point glass layer 37a fusing, occluding body 37b falls and blocks bleeding point, and the gap between occluding body and bleeding point is filled by the low melting point glass layer melting gradually, thereby realizes hermetic seal.
After sealing, sealing member has higher strength and stiffness, has increased the reliability of this sealing structure, has improved the work-ing life of vacuum glass; Meanwhile, operate easylier, working efficiency improves greatly.
Below only described by reference to the accompanying drawings several preferred embodiments of the application, but the application is not limited to this, every those of ordinary skill in the art are not departing under the application's spirit, and any improvement and/or the distortion made all belong to the application's protection domain.
