Description

Technical Field

[0001] The utility model relates to the technical field of picture frame glass, in particular to a micro-steel picture frame glass and an installation sealing structure. Background Art

[0002] Slightly tempered glass is the abbreviation of semi-tempered glass, which is also called heat-strengthened glass. Semi-tempered glass is a type between ordinary flat glass and tempered glass. It has some advantages of tempered glass, such as higher strength than ordinary float glass, which is twice that of ordinary float glass. At the same time, it avoids the weaknesses of tempered glass, such as poor flatness, easy self-explosion, and overall shattering once damaged.

[0003] At present, the micro-reinforced glass used for picture frames on the market usually adopts a laminated glass design to improve the defects of micro-reinforced glass. However, when the picture frame falls, the laminated glass will be damaged or broken, which will cause damage to the exhibits inside. Therefore, in addition to optimizing the design of the picture frame glass, it is also necessary to install sealing strips on the edges of the glass plate.

[0004] In order to ensure the sealing between the existing picture frame and the laminated glass, glue and sealing strips are used to bond and seal based on moisture-proof and waterproof considerations. When the glue enters the sealing strip, a large number of voids are easily generated during bonding because the laminated glass and the sealing strip are two planes directly squeezed and fitted. In actual operation, repeated exhaust is required to eliminate the voids, because the presence of voids will lead to the existence of sealing voids, resulting in a decrease in the sealing effect. Utility Model Content

[0005] The technical problem to be solved by the utility model is that the existing common laminated tempered glass has poor impact resistance, and its tensile and torsion resistance are also relatively poor. At the same time, a sealing structure is to be studied so that the sealing structure can be tightly bonded with the picture frame and the laminated glass without generating voids.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A micro-steel picture frame glass comprises a glass body, wherein the glass body comprises a lower layer of glass, a glue layer and an upper layer of glass which are stacked in sequence.

[0008] Furthermore, the thickness of the lower glass and the upper glass are both 2 mm, and the adhesive layer is a glass film with a thickness of 0.76-0.89 mm.

[0009] Furthermore, the glass film is a PVB film with a thickness of 0.76 mm.

[0010] Furthermore, the glass film is a SGP film, and its thickness is 0.89 mm.

[0011] A micro-steel picture frame glass structure comprises a glass body and a sealing strip arranged at the edge of the glass body. The cross section of the sealing strip is a "U"-shaped structure, and the width of the inner surface thereof decreases from bottom to top.

[0012] Furthermore, a hemispherical soft protrusion in a rectangular array is provided at the bottom of the inner surface of the sealing strip, and a cross-shaped groove is provided at the top of the hemispherical hard protrusion, which extends from the top to the bottom.

[0013] Furthermore, the sealing strip and the hard raised portion are an integrated structure.

[0014] Furthermore, a connecting block with a "T"-shaped cross-section is fixedly connected to the bottom of the outer surface of the sealing strip.

[0015] Working principle and beneficial effects:

[0016] (1) The glass body composed of the upper glass, the lower glass and the middle glue layer is laminated glass, which has strong tensile and torsional resistance as well as strong impact resistance.

[0017] (2) When the edge of the glass body is sealed and glued, the glass body is embedded in the "U"-shaped sealing strip, and glue is injected between the interlayers. Due to the hard raised part, during construction, only direct pressing is required without repeated exhaust, so that the glue between the interlayers can be fully filled, avoiding the problem of voids between the glue and the glass body, thereby improving the sealing performance.

[0022] The present invention can be better understood according to the following embodiments.

[0023] The structures, proportions, sizes, etc. illustrated in the drawings of the specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the utility model, so they have no substantial technical significance. Any modification of the structure, change of the proportion relationship or adjustment of the size, without affecting the effect and purpose that can be achieved by the utility model, should still fall within the scope of the technical content disclosed by the utility model. At the same time, the terms such as "upper", "lower", "front", "back", "middle" and so on quoted in this specification are only for the convenience of description, and are not used to limit the scope of the implementation of the utility model. The change or adjustment of their relative relationship should also be regarded as the scope of the implementation of the utility model without substantial change of the technical content.

[0024] Embodiment 1:

[0025] like Figure 1 As shown, a micro-steel picture frame glass includes a glass body, wherein the glass body includes a lower glass 1, a glue layer 2, and an upper glass 3 which are stacked, wherein the glue layer 2 can be made of a PVB sheet. Compared with ordinary laminated glass, the glue layer 2 uses a 0.76mm thick PVB sheet, which can effectively isolate noise and prevent ultraviolet rays from damaging exhibits.

[0026] Implementation 2:

[0027] A micro-steel picture frame glass comprises a glass body, wherein the glass body comprises a lower layer of glass 1, a glue layer 2, and an upper layer of glass 3 which are stacked, wherein the glue layer 2 can be made of an SPG sheet. Compared with ordinary laminated glass, the glue layer 2 uses an SPG sheet with a thickness of 0.89 mm, which has better impact resistance and far exceeds ordinary laminated glass.

[0028] Implementation 3:

[0029] like Figure 2 , 3 As shown, a micro steel picture frame glass structure includes a sealing strip, the cross section of the sealing strip 4 is a "U"-shaped structure, the width of the inner surface of which decreases from bottom to top, and the bottom of the inner surface of the sealing strip 4 is provided with a hemispherical hard protrusion 5 in a rectangular array, the sealing strip 4 and the hard protrusion 5 are an integrated structure, the sealing strip 4 and the hard protrusion 5 are both made of rubber material, but the degree of vulcanization is different, the hard protrusion 5 can be improved by increasing the degree of vulcanization to increase the hardness, and when the hard protrusion 5 is vulcanized, other areas of the sealing strip 4 can be shielded. A cross-shaped groove 7 is provided on the top of the hard protrusion 5, and the cross-shaped groove 7 extends from the top to the bottom, and a connecting block 6 with a "T"-shaped cross section is fixedly connected to the bottom of the outer surface of the sealing strip 4.

[0030] The function of the hard raised portion 5 provided in this scheme is that when the glass body and the sealing strip 4 are sealed and glued, the glass body is embedded in the "U"-shaped sealing strip 4, and glue is injected between the interlayers. Due to the provision of the hard raised portion 5, firstly, a certain distance is maintained between the glass body and the bottom of the inner surface of the sealing strip 4, which can facilitate the glue to flow fully between the interlayers during pre-extrusion; thereafter, by pressing the glass body up and down 2-3 times, pressure is applied to the hard raised portion 5. Since the sealing strip 4 is softer than the hard raised portion 5, the squeezed hard raised portion 5 will cause it to sink near the sealing strip 4 and then be lifted up, so that the glue in the interlayer between the glass body and the sealing strip 4 can be fully filled, thereby avoiding the occurrence of cavity defects and improving the sealing performance.

[0031] If the hard protrusion 5 is replaced by a protrusion made of rubber of the same material as the sealing strip 4, and the hardness thereof is exactly the same, then the effect of pressing the protrusion will be deteriorated, and it will not be of much help in solving the cavity defect.

[0032] If the hard protrusion 5 is replaced with a soft protrusion made of rubber softer than the sealing strip 4, pressing the soft protrusion will basically not solve the void defect.

[0033] The cross-shaped groove 7 opened at the top of the hard protrusion 5 extends to the bottom of the hard protrusion 5. When pressed, it will also enhance the impact effect of the glue between the top of the hard protrusion 5 and the edge of the glass body, which is helpful to solve the cavity defect.

[0034] A slot adapted to the connection block is provided on the inner surface of the picture frame, and the connection block 6 is inserted into the slot to improve the stability of the connection structure.
