All other embodiments, based on the embodiments of the utility model, which are apparent to those of ordinary skill in the art without inventive faculty, are intended to be within the scope of the utility model. Thus, the following detailed description of the embodiments of the utility model, as presented in the figures, is not intended to limit the scope of the utility model, as claimed, but is merely representative of selected embodiments of the utility model. All other embodiments, based on the embodiments of the utility model, which are apparent to those of ordinary skill in the art without inventive faculty, are intended to be within the scope of the utility model.

In the description of the present utility model, the terms "first," "second," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature. In the description of the present utility model, the meaning of "a plurality" is two or more, unless explicitly defined otherwise.

Referring to fig. 1 to 6, a vacuum glass with a sealing strip includes a sealing strip 1, an upper glass 2, and a lower glass 3; the upper glass 2 and the lower glass 3 are overlapped and a vacuum gap is reserved; the sealing strip 1 is arranged around the upper glass 2 and the lower glass 3 and seals the vacuum gap.

As a further improvement, in order to avoid the problems of partial aging, shrinkage, sand hole, cracks, and the like of the weather strip 1 exposed in the air, the contact surface of the projecting portion 12 of the weather strip 1 projecting into the vacuum gap with the upper glass 2 and the lower glass 3 is formed with a vacuum belt, and the effect of secondarily reinforcing the projecting portion 12 by the vacuum belt is made because the vacuum belt has the negative pressure of the same pressure to increase the friction between the projecting portion 12 and the upper glass 2 and the lower glass 3, thereby realizing the fixing effect, and the secondary formation of the vacuum belt can effectively prevent the aging of the contact surface, thereby making the durability effect of the vacuum glass better.

The sealing strip 1 comprises a sealing part 11 and an extending part 12, wherein one end of the extending part 12 is fixedly connected to the middle part of the sealing part 11; the sealing part 11 is attached to the edges of the upper glass 2 and the lower glass 3; the extending part 12 extends into the vacuum gap, and the surface of the extending part 12 is in mirror fit with the upper glass 2 and the lower glass 3;

The surface of the projecting portion 12 is provided with a groove 121, and the groove 121 surrounds the outer periphery of the upper glass 2 and the lower glass 3. As a further development, preferably, the extension 12 is provided with at least two sets of grooves 121; as a further improvement, the recess 121 is preferably biased to the left in the middle of the projecting portion 12. This is to equalize the spacing between the groove 121 and the plurality of support columns 21, thereby ensuring more uniform stress on the upper glass 2; in other words, if the recess 121 is too far to right or/and left, the spacing between the recess and the support columns 21 is not equal, the stress area of the extending portion 12 will be deviated, and the extending portion 12 will be damaged or deformed, which is not beneficial for long-term use.

The cross section of the groove 121 is semicircular, square or rectangular. Preferably, the cross section of the groove 121 is semicircular. The semicircular groove is smoother in shape and has no edges and corners, so that stress can be dispersed around the groove when the groove is stressed, the force is distributed more uniformly, and the groove is not easy to deform; the square groove or the rectangular groove is provided with edges and corners, so that the stress can be along the same direction, and the stress concentration degree is improved. Therefore, under the same load, the stress concentration in the square groove or the rectangular groove is greater, and the material is liable to be damaged and deformed.

The upper end of the sealing part 11 is higher than the upper surface of the upper glass 2, and the lower end of the sealing part 11 is lower than the lower surface of the lower glass 3; further, the distance by which the upper and lower ends of the sealing portion 11 protrude from the upper glass 2 and the lower glass 3 is 0.5 to 1mm. In one embodiment, the upper and lower ends of the sealing portion 11 protrude from the upper glass 2 and the lower glass 3 by a height of about 1mm in order to protect the glass from being pressed by hard objects when mounted. If the height is too high, subsequent installation may be affected; if the height is too low, the vacuum glass cannot be protected, resulting in the vacuum glass being squeezed by hard objects and damaged.

The contact parts between the upper glass 2, the lower glass 3 and the sealing strip 1 are coated with sealant; preferably, the sealant is a UV glue layer.

The grooves 121 are symmetrically disposed at the upper and lower surfaces of the penetration portion 12.

A plurality of support columns 21 are adhered between the upper glass 2 and the lower glass 3; the supporting columns 21 are arranged at equal intervals along the surface of the lower glass 3, so that the surface of the upper glass 2, which is contacted with the supporting columns 21, is stressed uniformly under the condition of external force, the sealing glue between the upper glass 2 and the supporting columns 21 is prevented from cracking or separating, the connectivity between the upper glass 2 and the supporting columns 21 is improved, the firmness of the upper glass 2 and the supporting columns 21 is further improved, and on the other hand, the sealing of the upper glass 2 is facilitated.

Naturally, if the sealing performance of the vacuum glass is improved, the heat insulation and noise reduction functions of the vacuum glass are also correspondingly better.

It should be noted that, the diameter of the support column 21 is the vacuum degree of the vacuum glass inner cavity, the higher the vacuum degree is, the larger the corresponding strength of the support column 21 is, the larger the diameter is, and the specific requirement is selected according to the actual requirement, and will not be described herein.

As a further improvement, preferably, the outer edge of the sealing portion 11 is arc-shaped; the sealing part 11 can disperse impact force under the impact of external force, so that the force is prevented from being concentrated at one point, and vacuum glass is well protected and prevented from being damaged; further, the sealing part 11 completely wraps the outermost proportional edges of the upper glass 2 and the lower glass 3, so as to reduce the side edges of the upper glass 2 and the lower glass 3 and cancel the right-angle edge chamfering process, and also can realize the protection of personnel during carrying, and if necessary, the sealing part 11 can be turned over outwards to wrap the glass edges completely.

As a further improvement, the cross section of the sealing portion 11 is preferably "T" shaped. Furthermore, the T-shaped side surface is surrounded, so that the gluing processing of glass corners can be greatly reduced, and the on-site installation and protection are convenient to use.

It is worth to say that the sealing strip 1 with the T-shaped indent forms a vacuum waterproof wall with the vacuum lamination of the inner side surface of the glass, which provides a guarantee for the negative pressure performance of the hollow inner glue.

When the original glass is installed, sealant is smeared on one glass, then the two glasses are stuck, and small holes are reserved between the two glasses, so that air between the two glasses is pumped out, when the two glasses are in a vacuum state, the small holes are blocked, and thus the vacuum glass is formed, and the vacuum glass can be formed in the mode, but the mode is too complicated in the actual operation process; preferably, a plurality of equally spaced support columns 21 are arranged on the upper glass 2, the upper glass is placed on a workbench surface in a vacuum environment, the upper glass 2 is coated with sealant, sealing strips 1 are placed on the peripheral edges of the upper glass, and then the lower glass 3 is pressed together with the upper glass 2 and the sealing strips 1 through equipment, and the three are fixedly sealed, wherein the sealing strips 1 can facilitate limiting the lower glass 3, ensure that the lower glass 3 is placed flush with the upper glass 2, and improve the tightness of the whole vacuum glass. Therefore, compared with the original vacuum glass mounting and vacuumizing mode, the vacuum glass mounting device has better effect.

The above description is only of the preferred embodiments of the present utility model and is not intended to limit the present utility model, and various modifications and variations may be made to the present utility model by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
