[0002] In modern architecture, vacuum glass is widely used due to its excellent heat insulation and sound insulation performance. The core of vacuum glass lies in its internal vacuum layer, which can effectively isolate heat transfer and sound propagation. However, manufacturing and maintaining this vacuum layer face many technical challenges, especially how to design an effective sealing structure to ensure the tightness of the vacuum layer, prevent air penetration, and ensure the long-term maintenance of the vacuum state.

These problems often lead to the failure of the vacuum layer, thereby affecting the heat insulation and sound insulation effects of the glass and shortening the service life of the vacuum glass. Therefore, developing a new sealing structure is of great significance for improving the performance and reliability of vacuum glass. Summary of the Utility Model

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model. Specific embodiment one:

[0031] Please refer to Figures 1-6As shown in the figure, the utility model relates to a sealing structure of a vacuum glass, which includes a sealing support ring 1 arranged between the inner layer glass 2 and the outer layer glass 3 along its edge part. At least one corner of the sealing support ring 1 is integrally formed with a conical cylinder part 11, and the outer diameter of the inner end of the conical cylinder part 11 is greater than the outer diameter of the inner end. A plug tube 4 is inserted and installed in the inner hole of the conical cylinder part 11. The plug tube 4 can move in the conical cylinder part 11, and a seal is formed between the conical cylinder part 11 and the outer wall of the plug tube 4. A vacuum pumping device is connected to the plug tube 4 to perform vacuum pumping on the space inside the inner layer glass 2, the outer layer glass 3, and the sealing support ring 1.

[0032] In addition, the thickness of the vacuum layer of the vacuum glass is small. In order to accommodate the conical cylinder part 11, a conical surface groove is opened at the connection between the inner layer glass 2, the outer layer glass 3, and the conical cylinder part 11. A row of first annular grooves 17 is axially opened on the outer wall of the conical cylinder part 11. And in order to ensure the connection tightness between the conical cylinder part 11 and the inner layer glass 2 and the outer layer glass 3, sealant is applied outside the conical cylinder part 11 to connect and seal with the conical surface groove, filling all voids, effectively ensuring the connection tightness between the conical cylinder part 11 and the inner layer glass 2 and the outer layer glass 3.

[0033] In order to ensure the seal between the plug tube 4 and the conical cylinder part 11 after vacuum pumping, a cylindrically closed cylinder 12 is integrally formed coaxially at the inner end of the conical cylinder part 11, and the cylinder 12 is coaxially arranged with the conical cylinder part 11. At least two ventilation holes 13 are opened at one end of the cylinder 12 close to the conical cylinder part 11. A plunger 14 that is hermetically connected to the inner cavity of the plug tube 4 is integrally formed on the inner bottom surface of the cylinder 12. An external chamfer is opened on the end face of the plunger 14. An internal chamfer is opened at the connection end of the plug tube 4 and the plunger 14. After vacuum pumping is completed, the plug tube 4 is pushed inward along the axis of the conical cylinder part 11, and the plunger 14 is inserted into the plug tube 4 to achieve staggered plugging of the plug tube 4, effectively ensuring the sealing stability after vacuum pumping.

[0034] In order to perform segmented continuous sealing on the relatively wide sealing support ring 1, a pair of first annular grooves 15 and a pair of second annular grooves 16 are symmetrically opened on the downward surface of the sealing support ring 1. The cross-section of the first annular groove 15 and the cross-section of the second annular groove 16 are both L-shaped structures.

[0035] In order to further reinforce the overall sealing mechanism after vacuum pumping, glass structural corners are injected with a glue gun between the annular surface of the sealing support ring 1 and three consecutive surfaces of the inner layer glass 2 and the outer layer glass 3 to form a glass structural glue layer 5. A number of layers of second annular grooves 18 are opened on the annular surface of the sealing support ring 1 to further improve the connection stability between the glass structural glue layer 5 and the sealing support ring 1.

[0036] In order to facilitate the operation of the intubation tube 4, a limiting plate 41 is fixed on the outer wall of the intubation tube 4. The sealing of the intubation tube 4 is completed when the limiting plate 41 comes into contact with the sealing support ring 1. At the same time, glass structural adhesive is injected at the outer end of the intubation tube 4 and connected to the glass structural adhesive layer 5 as a whole.
