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 sheet glass 20 and lower sheet glass 10; Upper sheet glass 20 and lower sheet glass parallel stacking Shang Xia 10, centre is provided with upholder 11, and periphery 12 seals; On upper sheet glass 20, be provided with bleeding point 30, the opening part of bleeding point 30 is provided with the sealing member of being made up of metallic substance 36 of the rear sealing of fusing bleeding point 30.The shape of sealing member can be to be spheroid, spheroid, cone or other shapes.
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 sealing member 36 adapts.The diameter of sealing member 36 is 1.5-2.5 times of bleeding point diameter.
In addition as shown in Figure 6, the opening part of bleeding point 30a also can facilitate spheroid to place by counterbore or other forms of structure are set.As shown in Figure 7, the form of bleeding point 30b can also be conical bore, and 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.
As shown in Figure 3, the inside surrounded surface of bleeding point and tapered hole is prefabricated with the metal layer 38 being fixed together with sheet glass.About preparation and the method for prefabricating of metal layer 38, the applicant elaborates in patent of invention CN102079619B, does to quote from this, repeats no more.
Sealing member 36 is made up of low melting point metal material, and this metallic substance can be tin or tin alloy, indium or indium alloy.
