Description

Technical Field

[0001] This utility model relates to the field of explosion-proof glass technology, and in particular to a novel double-layer explosion-proof glass structure. Background Technology

[0002] Explosion-proof glass is a type of safety glass made through a special process. Its core design goal is to withstand violent impacts and prevent glass shards from flying.

[0003] Currently, explosion-proof glass is typically installed on the observation window of a vacuum chamber for protection. However, the explosion-proof glass is usually installed directly on the observation window of the vacuum chamber, and then glue is injected to fix it at the edges. However, because the surface of the explosion-proof glass is smooth, the contact area between the glue and the glass is small, resulting in unstable installation and poor installation effect. Furthermore, when the explosion-proof glass is subjected to impact, stress concentration occurs at the connection between the edge of the explosion-proof glass and the observation window, making it prone to damage and resulting in poor protective effect.

[0004] Therefore, we provide a novel double-layer explosion-proof glass structure. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned technical problems by providing a novel double-layer explosion-proof glass structure. This structure uses an energy-absorbing plate to absorb and eliminate the impact force on the first and second glass plates, while also protecting the edges of the first and second glass plates.

[0006] In view of this, the present invention provides a novel double-layer explosion-proof glass structure, including a first glass plate and a second glass plate. The first glass plate and the second glass plate are provided with first receiving grooves on both sides of their respective edges. The first glass plate and the second glass plate are provided with U-shaped plates at both ends. The two ends of each U-shaped plate extend into the corresponding first receiving groove.

[0007] An energy-absorbing plate is installed between the two U-shaped plates. The energy-absorbing plate is located between the first glass plate and the second glass plate, and the adjacent surfaces of the first glass plate and the second glass plate are bonded to the energy-absorbing plate.

[0008] Each U-shaped plate has openings on both sides, and each opening slot has a strip connecting plate inside. The two ends of each strip connecting plate are bent, and each end of each strip connecting plate is equipped with a connecting piece. Each side of each U-shaped plate has a second receiving slot, and each connecting piece extends into the corresponding second receiving slot.

[0009] Each of the strip connecting plates has several spacers installed on its side, with a gap between adjacent spacers.

[0010] Preferably, the energy-absorbing plate is made of polycarbonate material.

[0011] Preferably, there is a gap between the edge of each of the spacers and the edge of the opening slot.

[0012] Preferably, each of the connecting pieces and the U-shaped plate has mounting holes on both sides of its end, and each mounting hole has a fastening bolt inside. Several threaded holes are also provided on the edges of the first glass plate and the second glass plate that are far apart from each other. One end of each fastening bolt passes through the mounting hole and extends into the corresponding threaded hole, and each fastening bolt is threadedly connected to the corresponding threaded hole.

[0013] Preferably, a buffer rubber layer is installed on the side of each of the first receiving slots. When the two ends of the U-shaped plate extend into the corresponding first receiving slot, the side of the buffer rubber layer contacts and connects with the side of the end of the U-shaped plate.

[0014] Preferably, each of the connecting pieces has a groove on its side, the groove being coaxially arranged with the mounting hole, and when the fastening bolt is tightened, the end of the fastening bolt is located inside the groove.

[0018] 2. This utility model, by forming an accommodating space between the spacer and the strip connecting plate, can increase the contact area with the adhesive during the connection with external equipment, thereby increasing installation stability and improving installation effect.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0027] A novel double-layer explosion-proof glass structure, such as Figures 1-4 As shown, it includes a first glass plate 1 and a second glass plate 3. The first glass plate 1 and the second glass plate 3 are provided with first receiving grooves 11 on both sides. The first glass plate 1 and the second glass plate 3 are provided with U-shaped plates 4 at both ends. The two ends of each U-shaped plate 4 extend into the corresponding first receiving groove 11. The first glass plate 1 and the second glass plate 3 are both made of tempered glass, or other high-strength glass materials. In this way, when the first glass plate 1 and the second glass plate 3 are subjected to external impact force, the impact force will be transmitted to the U-shaped plates 4. The edges of the first glass plate 1 and the second glass plate 3 can be protected by the U-shaped plates 4.

[0028] like Figure 1 and Figure 4As shown, an energy-absorbing plate 2 is installed between the two U-shaped plates 4. The energy-absorbing plate 2 is located between the first glass plate 1 and the second glass plate 3, and the adjacent surfaces of the first glass plate 1 and the second glass plate 3 are all bonded to the energy-absorbing plate 2. The energy-absorbing plate 2 is made of polycarbonate material, or other transparent organic materials with energy absorption. The energy-absorbing plate 2 can bond the first glass plate 1 and the second glass plate 3 together, absorb energy and protect the first glass plate 1 or the second glass plate 3 from the impact force. When the first glass plate 1 or the second glass plate 3 breaks, the energy-absorbing plate 2 can stick the debris to prevent the debris from splashing into the surrounding environment.

[0029] like Figure 1 Each U-shaped plate 4 has openings 7 on both sides, and each opening 7 has a strip connecting plate 5 inside. The two ends of each strip connecting plate 5 are bent, and each end of each strip connecting plate 5 is equipped with a connecting piece 8. Each side of each U-shaped plate 4 has a second receiving groove 12, and each connecting piece 8 extends into the corresponding second receiving groove 12. Each side of each strip connecting plate 5 is equipped with several spacers 6, and there is a gap between two adjacent spacers 6. In use, a receiving space is formed between the spacers 6 and the strip connecting plate 5. When the edges of the first glass plate 1 and the second glass plate 3 are glued and installed with external equipment, the receiving space can increase the contact area between the glue and the U-shaped plate 4, and improve the installation stability.

[0030] like Figure 2 As shown, there is a gap between the edge of each spacer 6 and the edge of the opening slot 7, so that the spacer 6 will not obstruct the connection of the U-shaped plate 4 to external equipment.

[0031] like Figure 2 and Figure 3 As shown, each connecting piece 8 and the U-shaped plate 4 have mounting holes 10 on both sides of their ends. Each mounting hole 10 has a fastening bolt 9 inside. Several threaded holes 15 are provided on the edges of the first glass plate 1 and the second glass plate 3 that are far apart from each other. One end of each fastening bolt 9 passes through the mounting hole 10 and extends into the corresponding threaded hole 15. Each fastening bolt 9 is threadedly connected to the corresponding threaded hole 15. Through the cooperation of the fastening bolt 9 with the mounting hole 10 and the threaded hole 15, the connecting piece 8 can be connected to the U-shaped plate 4, and the U-shaped plate 4 can also be connected to the first glass plate 1 and the second glass plate 3 together, so that the connection is stable.

[0032] like Figure 3 and Figure 4As shown, each of the first receiving slots 11 has a buffer rubber layer 14 installed on its side. When the two ends of the U-shaped plate 4 are inserted into the corresponding first receiving slot 11, the side of the buffer rubber layer 14 contacts and connects with the side of the end of the U-shaped plate 4. The buffer rubber layer 14 can buffer and protect the U-shaped plate 4 from the first glass plate 1 and the second glass plate 3, preventing the U-shaped plate 4 from damaging the first glass plate 1 or the second glass plate 3. Furthermore, the elasticity of the buffer rubber layer 14 can make the connection of the fastening bolt 9 more secure.

[0033] like Figure 2 As shown, the side of the connecting piece 8 is provided with a groove 13. The groove 13 is coaxially arranged with the mounting hole 10. When the fastening bolt 9 is tightened, the end of the fastening bolt 9 is located inside the groove 13. The end of the fastening bolt 9 can be stored in the groove 13. In this way, when the fastening bolt 9 is tightened, it will not hinder the installation of the U-shaped plate 4 on the external equipment.

[0034] In use, the operator moves the first glass plate 1 and the second glass plate 3 from one end of the U-shaped plate 4 into the space between the two U-shaped plates 4. Then, the first glass plate 1 and the second glass plate 3 are bonded together by the energy-absorbing plate 2. Next, the strip connecting plate 5 is moved into the opening groove 7, and the connecting piece 8 is moved into the second receiving groove 12. Then, one end of the fastening bolt 9 is passed through the corresponding mounting hole 10 and screwed into the threaded hole 15, thus fixing the strip connecting plate 5 and the U-shaped plate 4 together. At the same time, the U-shaped plate 4 is fixed together with the first glass plate 1 and the second glass plate 3, and the connection is stable. In this way, when the U-shaped plate 4 is connected to the external equipment, the spacer 6 increases the contact area between the glue and the strip connecting plate 5, thereby improving the installation stability.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
