Description

Technical Field

[0001] The utility model relates to a multi-layer glass, in particular to a high-strength anti-smashing and bullet-proof glass. Background Art

[0002] In the current technical field, the performance characteristics of multi-layer glass have received significant attention due to its widespread use in buildings, vehicles and other applications with high safety requirements. These multi-layer glass structures usually face a major technical challenge, namely, limitations in impact strength. In particular, these glass structures are easily shattered after being impacted, and their fragments may be separated from the main structure, causing serious safety hazards.

[0003] To solve this problem, the prior art proposes a solution of adding an intermediate layer between glass layers. In particular, using transparent acrylic material as the intermediate layer has become a common method to improve the impact resistance of glass. This structure can improve the overall impact resistance of glass to a certain extent, but its disadvantage is that even if the impact resistance is improved, once the glass is broken, the fragments may still be separated from the main body, posing a safety hazard.

[0004] Further improvements include introducing a transparent flexible layer between the glass and the interlayer and bonding the glass to the flexible layer. This structural design can effectively prevent fragments from falling off when the glass breaks, improving safety during use. However, this improvement scheme leads to a decrease in the strength and stability of the overall structure, affecting the service life and durability of the glass.

[0005] In view of the above analysis, the prior art still has deficiencies in improving the safety and impact resistance of multi-layer glass. Therefore, the present invention aims to provide a new type of multi-layer glass structure, which can not only effectively improve the impact resistance, but also improve the stability and durability of the overall structure while keeping the fragments from falling off. Summary of the invention

[0006] In order to solve the above problems, the utility model provides a high-strength anti-smash bulletproof glass, which can effectively solve many deficiencies in the prior art by adding middle plates on both sides and hollowing out the middle plates, and positioning the upper and lower ends of the transparent flexible layer at the upper and lower ends.

[0007] The utility model is realized by the following technical scheme: a high-strength anti-smash and bullet-proof glass, comprising:

[0008] Two transparent middle plates, a first glass layer is installed on one side of the middle plate, and a second glass layer is installed on the other side of the middle plate;

[0009] A transparent flexible layer, disposed between the first glass layer and the middle plate, and between the second glass layer and the middle plate, and used for bonding the glass layers on one side and bonding the middle plate on the other side;

[0010] The upper and lower butt joints of the two transparent middle plates are provided with elastic connecting columns. The upper and lower ends of the transparent flexible layer are bent toward the transparent flexible layer to form a bent connecting portion and then positioned between the two middle plates. The bent connecting portion is positioned up and down by the elastic connecting column.

[0011] As a preferred technical solution, the transparent flexible layer includes a transparent main body and a bending connection portion, and the bending connection portion is composed of an edging portion and a positioning portion. After the edging portion wraps the upper and lower end surfaces of the middle plate, the positioning portion is buckled between the two middle plates, so that an elastic hollow cavity is formed in the middle of the two middle plates after clamping and assembling.

[0012] As a preferred technical solution, a plurality of positioning holes are arranged on the positioning portion along the length direction of the positioning portion, and an elastic positioning column is fixedly bonded to the position corresponding to each positioning hole between the two middle plates, and both ends of the elastic positioning column are respectively fixedly bonded to the middle plates, and the elastic positioning columns pass through the positioning holes.

[0013] As a preferred technical solution, the elastic positioning column is supported by a transparent elastic rubber material, and the upper and lower ends of the transparent flexible layer are fixed by the elastic positioning column and fixedly clamped to the upper and lower ends of the two middle plates.

[0014] As a preferred technical solution, a transparent first adhesive layer is provided between the first glass layer, the second glass layer and the transparent flexible layer.

[0015] As a preferred technical solution, a transparent second adhesive layer is provided on the contact surface between the transparent flexible layer and the middle plate.

[0016] As a preferred technical solution, the two transparent middle plates are made of high-strength transparent plate material.

[0017] As a preferred technical solution, the two middle plates include a first middle plate and a second middle plate.

[0018] The beneficial effects of the utility model are as follows: the utility model is provided with two layers of transparent middle plates, which greatly enhances the impact resistance of the entire glass structure; the two layers of middle plates are respectively provided with elastic connecting columns at the joints of the upper and lower ends thereof, forming an elastic hollow cavity, so that the middle plates have excellent impact resistance and excellent elasticity, thereby significantly improving the anti-smashing effect;

[0019] In addition, the elastic connecting columns at the upper and lower ends not only enhance the overall stability of the structure, but also provide effective support for the positioning of the transparent flexible layer, so that the transparent flexible layer can be firmly combined with the middle plate by physical means, rather than relying solely on glue bonding. The advantage of this bonding method is that even during long-term use, there will be no interlayer separation problem caused by aging of the glue, thereby greatly improving the bonding and durability of the entire glass structure;

[0020] By using the transparent flexible layer, the utility model significantly improves the safety of the glass after it is broken.

[0030] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.

[0031] Any feature disclosed in this specification (including any additional claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0032] like Figure 1-Figure 3 As shown, the utility model is a high-strength anti-smash bulletproof glass, comprising two transparent middle plates, a first glass layer 1 is installed on one side of the middle plate, and a second glass layer 2 is installed on the other side of the middle plate. The first glass layer 1 and the second glass layer 2 can be made of tempered glass, and the thickness can be selected as needed. The two tempered glass layers are used as protective layers on the front and back sides; the transparent middle plate is used to increase the overall strength of the two glass layers after installation, thereby improving the strength of the entire multi-layer glass;

[0033] In order to increase the overall strength of the glass layer after being fixed and installed, and to prevent the falling of debris after the glass layer is broken, the present embodiment further includes a transparent flexible layer 6, which is arranged between the first glass layer 1 and the middle plate, and between the second glass layer 2 and the middle plate, and is used to bond the glass layer on one side and the middle plate on the other side. By providing the transparent flexible layer 6, the glass layer can be connected to the transparent flexible layer 6 even after being broken, so as to prevent the falling of debris;

[0034] Elastic connecting columns are provided at the upper and lower docking positions of the two transparent middle plates. The upper and lower ends of the transparent flexible layer 6 are bent toward the transparent flexible layer 6 to form a bent connection part and then positioned and installed between the two middle plates. The bent connection part is positioned up and down by the elastic connecting columns. By setting the elastic connecting columns, the two transparent middle plates have good elasticity and softness, which can provide good buffering protection when impacted, greatly improving the anti-smashing effect of the glass. At the same time, the upper and lower ends of the transparent flexible layer 6 are positioned by the elastic connecting columns, so that the upper and lower ends of the transparent flexible layer 6 are physically combined with the middle plate, and glue is used to bond them. A double bonding method is adopted to effectively improve the bonding strength of the transparent flexible layer 6, and prevent the transparent flexible layer 6 from being separated due to aging of the glue. The degree of integration is higher and the service life is longer.

[0035] like Figure 4-Figure 6As shown, the transparent flexible layer 6 includes a transparent main body portion 62 and a bending connection portion, wherein the bending connection portion is composed of a edging portion 61 and a positioning portion 63. After the edging portion 61 wraps the upper and lower end surfaces of the middle plate, the positioning portion 63 is buckled between the two middle plates, so that an elastic hollow cavity 7 is formed between the two middle plates after clamping and assembly. The bending connection portion is buckled between the two middle plates to form the elastic hollow cavity 7. At the same time, there are also elastic connecting columns to achieve elastic support to maintain the formation of the elastic hollow cavity 7. There is a certain elastic extrusion force between the two middle plates, so that the entire piece of glass has very good impact resistance when it is hit.

[0036] In order to achieve better bonding of the transparent flexible layer 6, in this embodiment, a plurality of positioning holes 64 are provided on the positioning portion 63 along the length direction of the positioning portion 63, and an elastic positioning column 9 is fixedly bonded to the position corresponding to each positioning hole 64 between the two middle plates, and the two ends of the elastic positioning column 9 are respectively fixedly bonded to the middle plates, and the elastic positioning columns 9 pass through the positioning holes 64. The transparent flexible layer 6 is positioned and assembled through the elastic positioning columns 9 and the positioning holes 64, so that the bonding strength is better, and the bonding and fixation can be completed even if the glue fails.

[0037] In order to increase the elastic impact capacity of the two middle plates and increase the anti-smashing ability of the double-sided glass, in this embodiment, the elastic positioning column 9 is supported by a transparent elastic rubber material, and the upper and lower ends of the transparent flexible layer 6 are fixed by the elastic positioning column 9, and the upper and lower ends of the transparent flexible layer 6 are fixed and clamped to the upper and lower ends of the two middle plates.

[0038] Among them, a transparent first adhesive layer 3 is arranged between the first glass layer 1, the second glass layer 2 and the transparent flexible layer 6, and a transparent second adhesive layer 8 is arranged on the contact surface between the transparent flexible layer 6 and the middle plate. The layers are bonded by glue, and the transparent flexible layer 6 is also positioned and combined by a positioning structure, and the double fixing method makes the bonding strength of the transparent flexible layer 6 higher.

[0039] In this embodiment, the two transparent middle plates are made of transparent acrylic material, which has good impact resistance and is not easy to break. The two middle plates include a first middle plate 4 and a second middle plate 5. Of course, the number of middle plates can also be increased as needed.

[0040] The utility model is provided with two layers of transparent middle plates, which greatly enhances the impact resistance of the entire glass structure. The two layers of middle plates are respectively provided with elastic connecting columns at the joints of the upper and lower ends thereof, forming an elastic hollow cavity, so that the middle plates have excellent impact resistance and excellent elasticity, thereby significantly improving the anti-smashing effect;

[0041] In addition, the elastic connecting columns at the upper and lower ends not only enhance the overall stability of the structure, but also provide effective support for the positioning of the transparent flexible layer, so that the transparent flexible layer can be firmly combined with the middle plate by physical means, rather than relying solely on glue bonding. The advantage of this bonding method is that even during long-term use, there will be no interlayer separation problem caused by aging of the glue, thereby greatly improving the bonding and durability of the entire glass structure;

[0042] By using the transparent flexible layer, the utility model significantly improves the safety of the glass after it is broken. When the glass is broken, the transparent flexible layer effectively prevents the fragments from falling, thereby greatly reducing the potential safety hazards.

[0043] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
