Description

Technical Field

[0001] The utility model belongs to the technical field of hollow glass, in particular to a hollow glass. Background Art

[0002] Insulating glass is a new type of building material that has good heat insulation, sound insulation, is beautiful and practical, and can reduce the weight of buildings. It is usually made of two (or three) pieces of glass, using a high-strength and high-airtightness composite adhesive to bond the glass sheets to an aluminum alloy frame containing a desiccant to produce high-efficiency sound and heat insulating glass.

[0003] In modern construction and renovation, the installation of insulating glass windows often requires highly precise prefabrication and installation. Typically, window locations are reserved during the initial construction phase, based on architectural drawings and designs. However, during actual construction, due to various factors (such as construction errors and deformation of building materials), the reserved window and door dimensions may differ from the actual dimensions required.

[0004] To ensure precise installation of windows and doors, decorators often need to perform on-site adjustments. This involves cutting window frames and replacing glazing to ensure they fit perfectly into the designated spaces. These on-site adjustments are not only labor-intensive and inefficient, but can also compromise the structural integrity and aesthetics of insulating glass windows.

[0005] For example, if the window frame needs to be cut to fit an incompletely aligned cutout, this not only increases installation time but can also lead to unstable window frames, reducing their insulation and sealing performance. In addition, frequent adjustments and cuts can lead to material waste, increasing overall construction costs. Utility Model Content

Therefore, other examples of exemplary embodiments can have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0046] Embodiment 1:

[0047] As shown in Figure 1 , Figure 2 and Figure 5 , the embodiment provides a hollow glass, which comprises two glass sheets 1 arranged in parallel and a sealing frame 2, a spacer 3 is arranged between the edges of the two glass sheets 1, and an air cavity 4 is formed between the two glass sheets 1 and the spacer 3, and the air cavity 4 is filled with mixed gas composed of air and krypton;

[0048] The sealing frame 2 is composed of an outer frame 21 and an inner frame 22, the inner frame 22 is connected with the glass sheet 1, and the outer frame 21 and the inner frame 22 are connected through an adjusting mechanism 5, which is used for adjusting the size of the sealing frame 2, so that the hollow glass can perfectly match the reserved space;

[0049] The adjusting mechanism 5 comprises a sliding groove 51 and a sliding plate 52 in sliding cooperation with the sliding groove 51, the sliding groove 51 is arranged at the left and right ends outside the inner frame 22, the sliding plate 52 is slidingly arranged inside the sliding groove 51, and the sliding plate 52 is connected with the outer frame 21, and a locking mechanism 6 is arranged to fix the relative position of the sliding plate 52 and the sliding groove 51.

[0050] In the cavity between the two glass sheets 1, the air and krypton gas are mixed in a specific ratio and injected into the cavity 4 through a specific device after sealing, ensuring that the gas in the cavity 4 can play a good heat and sound insulation performance during use. The spacer 3 is arranged at the edge of the two glass sheets 1 to ensure that the glass sheets 1 maintain a certain distance and prevent gas leakage. The assembled glass sheets 1 are combined with the inner frame 22, and at this time, the inner frame 22 is fixedly connected with the glass sheets 1 to ensure the stability of the two glass sheets. The outer frame 21 and the inner frame 22 are connected through the adjusting mechanism 5, and the adjusting mechanism 5 includes a sliding groove 51 arranged on the outer side of the inner frame 22 and a sliding plate 52 slidingly matched with the sliding groove 51. The installer moves the sliding plate 52 in the sliding groove 51 to adjust the size of the outer frame 21. Due to the cooperation of the sliding groove 51 and the sliding plate 52, the installer can adjust the size of the outer frame 21 according to the reserved installation space, so as to ensure that the size of the frame is adapted to the window space of different buildings. The adjustment process can be completed by simple sliding, which saves the trouble of multiple measurements and cutting in traditional installation. After adjustment, the locking mechanism 6 fixes the position of the sliding plate 52 and the sliding groove 51 to ensure that the size of the outer frame 21 does not deviate or move, thereby maintaining the stability and sealing of the hollow glass. After the sealing frame 2 is adjusted to the appropriate size, the connection between the outer frame 21 and the inner frame 22 is stable, and the overall sealing of the glass sheets 1 and the frame is guaranteed. Finally, the hollow glass perfectly fits the installation position and achieves the expected heat and sound insulation effect. The gas cavity 4 filled with krypton gas effectively improves the heat insulation performance of the glass and enhances the heat insulation effect of the hollow glass. In addition, the design of the gas cavity 4 can also significantly improve its sound insulation performance and reduce external noise interference. The adjusting mechanism 5 enables the size of the sealing frame 2 to be adjusted according to actual needs, avoiding problems caused by size mismatch during installation of traditional hollow glass, and increasing the adaptability of the hollow glass. The design of the adjusting mechanism 5 makes the installation process more simple and efficient, reduces the workload and error probability of the installer, and improves the installation efficiency and quality. The setting of the locking mechanism 6 ensures that the size of the frame after adjustment does not change over time, maintains the long-term stability and sealing of the glass, and thus improves the service life of the hollow glass.

[0058] A rotating shaft 67 is rotatably arranged on the ear plate 66;

[0059] A limiting plate 68 is arranged on the rotating shaft 67, and the limiting plate 68 is in an inclined state to realize abutting against the inner wall of the inner frame 22;

[0060] A connecting groove 69 is arranged on the groove 65 of the fixed cylinder 63 and is in communication with the guide groove 64;

[0061] A wedge-shaped block 610 is arranged on the rotating shaft 67, and one end of the wedge-shaped block 610 extends into the inside of the guide groove 64 through the connecting groove 69;

[0062] A torsion spring 611 is sleeved on both ends of the rotating shaft 67 and is arranged between the ear plate 66 and the limiting plate 68;

[0063] A push rod 612 is slidingly arranged in the guide groove 64, and the push rod 612 cooperates with the wedge-shaped block 610;

[0064] A guide rod 613 is arranged on the push rod 612, and the guide rod 613 is located in the guide groove 64 and is slidingly connected with the fixed cylinder 63;

[0065] A reset spring 614 is sleeved on the guide rod 613 and is arranged between the push rod 612 and the fixed cylinder 63;

[0066] A threaded cylinder 615 is arranged on the front side of the fixed cylinder 63, the outer side of the threaded cylinder 615 is provided with external threads, the inside of the threaded cylinder 615 is provided with an extension groove in communication with the guide groove 64, and the push rod 612 is slidingly connected with the extension groove;

[0067] A locking piece 616 is threadedly arranged on the external threads of the threaded cylinder 615, and the locking piece 616 is in contact with the inner frame 22 after being locked;

[0069] In the technical solution, when the position of the sliding plate 52 and the sliding groove 51 needs to be locked, the user pushes the push rod 612, the push rod 612 slides along the guide groove 64, and the guide rod 613 slides along the fixed cylinder 63, and the reset spring 614 is compressed. In the process, the push rod 612 cooperates with the wedge block 610 to push the wedge block 610 to rotate, the wedge block 610 drives the rotating shaft 67 to rotate, and the rotating shaft 67 drives the limiting plate 68 to rotate, so that the limiting plate 68 is rotated to be folded into the recess 65, and the torsion spring 611 is deformed. At this time, the user inserts the fixed cylinder 63 into the through groove 61 and the corresponding positioning hole 62, and slides along the through groove 61 to the appropriate position. Then the user releases the push rod 612, and the push rod 612 and the guide rod 613 move forward along the guide groove 64 under the reset action of the reset spring 614. At this time, the push rod 612 is out of contact with the wedge block 610, and the limiting plate 68 is reversely rotated to be opened under the reset action of the torsion spring 611, so that the limiting plate 68 is in contact with the inner wall of the inner frame 22 and abuts against the inner wall of the inner frame 22, generating a locking force to ensure the stable positioning of the sliding plate 52 in the sliding groove 51 and prevent the assembly from loosening or position deviation due to external force or vibration. The contact between the limiting plate 68 in the inclined state and the inner wall of the inner frame 22 provides effective abutting function, ensuring that the sliding plate 52 will not loosen due to external force or vibration during use, and the limiting plate 68 drives the rotating shaft 67 and the wedge block 610 to reversely rotate and reset. Then the user rotates the locking member 616, the internal thread in the locking member 616 is threadedly connected with the external thread of the threaded cylinder 615, so that the locking member 616 is screwed on the threaded cylinder 615, and after locking, it is in contact with the outer wall of the inner frame 22. Through the internal and external cooperation of the limiting plate 68 and the locking member 616, the stability of the assembly is further ensured. If the locking needs to be released, the user can operate in the reverse direction, so that the limiting plate 68 is folded into the recess 65, and the fixed cylinder 63 can be taken out of the through groove 61 and the positioning hole 62, thereby releasing the locking, ensuring the flexibility and reliability of the locking mechanism 6. Thus, an effective locking force is achieved to ensure the stable positioning of the sliding plate 52 in the sliding groove 51 and prevent the assembly from loosening or position deviation due to external force or vibration. This locking mechanism 6 not only provides stable locking, but also has the functions of flexible adjustment and safety protection, and is suitable for the requirements of position accurate control and locking stability in the process of assembling hollow glass.

[0070] Embodiment 2

[0071] The embodiment provides a hollow glass, in addition to the technical solutions of the above-mentioned embodiments, further having the following technical features.

[0072] As shown in Figure 1 and Figure 2 In the embodiment, the two glass sheets 1 are single-layer glass or laminated glass, and at least one glass sheet 1 is low-emissivity glass, which has excellent heat insulation performance.

[0073] In this technical solution, first, the glass sheet 1 is single-layer glass or laminated glass, which means it can have different layers in structure. Single-layer glass is suitable for general thermal insulation needs, while laminated glass can provide better safety and sound insulation effects. Second, at least one glass sheet 1 is low-e glass, which has excellent thermal insulation performance. Low-e glass can effectively reflect and isolate infrared radiation through coating or other processing techniques, thereby improving the thermal insulation capacity of the glass, reducing heat conduction, maintaining the stability of indoor temperature, and reducing the energy consumption of air conditioning and heating.

[0074] As shown in Figure 1 and Figure 2 , in this embodiment, the connection between the glass sheet 1 and the spacer 3 is provided with sealant 7.

[0075] In this technical solution, the sealant 7 plays a sealing role at the connection between the glass sheet 1 and the spacer 3, effectively preventing external substances such as air, moisture, and dust from entering the glass interior. This can maintain the dryness of the hollow glass interior, prevent water vapor condensation or mold growth, and ensure its long-term service life and performance. The sealant 7 is filled between the glass sheet 1 and the spacer 3, forming a uniform sealing layer, further enhancing the thermal and sound insulation effects of the glass. By reducing air flow and heat conduction, the sealant 7 helps improve the thermal and sound insulation performance of the hollow glass. The sealant 7 acts as a buffer, reducing the stress caused by the expansion or contraction of the glass due to temperature changes, enhancing the stability of the hollow glass structure, and avoiding uneven pressure between the glass sheet 1 and the spacer 3.

[0076] As shown in Figure 1 and Figure 2 , in this embodiment, the spacer 3 is an aluminum alloy spacer with added desiccant 8.

[0077] In this technical solution, the spacer 3 is located between the two glass sheets in the structure of the hollow glass, and its main function is to maintain a fixed distance of the hollow space. The desiccant 8 (usually molecular sieve, silica gel, or other hygroscopic materials) is added to the spacer 3. This desiccant 8 can effectively absorb the moisture and humidity inside the hollow glass, preventing moisture from entering the glass cavity, which is very important for maintaining the long-term performance of the glass, especially in humid environments. The desiccant 8 can prevent water vapor condensation, mold growth, or fog formation, thereby ensuring the clarity and structural stability of the glass.

[0078] Specifically, when there is moisture inside the hollow glass, the moisture may generate frost or fog inside the glass with temperature changes, which not only affects the visual effect, but also may cause corrosion between the glass sheets 1. The desiccant 8 can continuously absorb moisture, keep the inside of the glass dry, effectively prevent the formation of frost and fog, keep the glass surface clear, and prolong the service life of the hollow glass. The thermal insulation effect of the hollow glass depends largely on the air or gas layer inside it, and the presence of moisture will affect the thermal insulation effect of the gas layer. The desiccant 8 helps to maintain the stability of the hollow layer by absorbing moisture, improves the thermal insulation performance of the glass, and reduces heat conduction. This is particularly important in energy-saving buildings or high-performance windows, which helps to improve the energy efficiency of the building and reduce indoor temperature fluctuations. The spacer bar 3 itself is made of aluminum alloy material, which has the characteristics of light weight, high strength, and corrosion resistance. The aluminum alloy not only enhances the structural strength of the hollow glass, but also prevents corrosion or wear caused by environmental changes. In addition, the aluminum alloy material has good processability and adaptability, making it easy to produce spacer bars 3 with precise dimensions and shapes, ensuring the assembly accuracy of the hollow glass. The aluminum alloy spacer bar 3 with desiccant 8 not only controls moisture, but also reduces the air pressure difference inside and outside the hollow glass through the hygroscopic effect, which helps to maintain the sealing of the glass. This can prevent air, moisture, and other substances from entering the glass cavity, further enhancing the sealing effect and thermal insulation performance of the glass.

[0079] As shown in Figure 1 In this embodiment, the optimized metal film layer 9 is provided on the opposite surface of the two glass sheets 1, and the metal film layer 9 is in contact with the spacer bar 3 and the sealant 7.

[0080] In this technical solution, the metal film layer 9 generally refers to a low-emissivity coating (such as a thin film of silver, aluminum, or other metal materials), which mainly functions to reflect infrared radiation, thereby improving the thermal insulation performance of the hollow glass. This metal film layer 9 can effectively reflect heat (such as solar radiation) from the outside and maintain the indoor temperature, or reflect indoor heat in cold seasons, reducing heat loss, thereby improving the energy-saving effect of the glass.

[0081] In summer, the metal film layer 9 reflects the infrared radiation of the sun, reducing the heat entering the room and lowering the air conditioning load. In winter, the metal film layer 9 reflects the heat radiation of the room, keeping the room warm and reducing the energy consumption of heating. This low-emission effect helps to improve the energy efficiency of buildings, reduce energy consumption, and meet the requirements of modern green buildings. The addition of the metal film layer 9 also improves the thermal stability of the glass. The metal film has a certain strengthening effect on the surface of the glass, which can evenly distribute the heat and reduce the risk of glass cracking or damage caused by thermal stress due to rapid or excessive temperature changes. The metal film layer 9 can also improve the optical properties of the hollow glass to some extent, such as transmittance and reflectance, making the glass have good light transmittance while controlling the reflection and scattering of light to some extent. By appropriately designing the thickness and material of the metal film layer 9, the optical properties of the glass can be adjusted to achieve both good visibility and optimized indoor lighting effects.

[0082] The main function of the metal film layer 9 in the hollow glass is to improve the thermal insulation performance, improve the optical properties, enhance the structural stability and corrosion resistance of the glass. Combined with the spacer 3 and the sealant 7, not only the performance of the hollow glass is optimized, but also its energy-saving effect, sound insulation effect, durability, stability and reliability in long-term use are effectively improved. Therefore, this design can provide significant advantages in energy saving, environmental protection, comfort and structural strength, etc.

[0083] As shown in Figure 1 and Figure 2 , in this embodiment, the thickness of the glass sheet 1 is optimized to be 2-10 mm, and the width of the air cavity 4 is 6-20 mm to ensure the best thermal and sound insulation effects.

[0084] In the present technical solution, the thickness of the glass sheet 1 has a significant impact on the thermal insulation performance of the hollow glass. Thicker glass sheet 1 can reduce heat conduction through the glass and improve its thermal insulation capacity. When the thickness of the glass sheet 1 is between 2-10mm, it can provide sufficient thermal insulation effect without adding too much weight or causing excessive light reflection. The thickness of the glass sheet 1 is closely related to the sound insulation effect of the hollow glass. Thicker glass sheet 1 can effectively block the transmission of sound and reduce the penetration of noise. In practical applications, the appropriate thickness of the glass sheet 1 is usually selected according to the needs to achieve the desired sound insulation effect. For example, thicker glass sheet 1 can better isolate external traffic noise, industrial noise, etc., and improve the quiet environment indoors. The cavity width plays a crucial role in the thermal insulation performance and sound insulation performance of the hollow glass. Proper cavity width can provide better gas isolation and reduce heat transfer through the hollow layer; wider cavity can more effectively isolate external noise, as it provides a thicker layer of air or gas that can reduce sound conduction. Proper thickness of the glass sheet 1 and cavity width not only provide good energy-saving effect and thermal insulation effect, but also effectively isolate external noise and improve the comfort of the living or working environment.

[0085] The embodiments of the present application are described above in conjunction with the drawings, and the embodiments and features in the present application can be combined with each other without conflict, and the present application is not limited to the specific embodiments described above. The specific embodiments described above are only illustrative, not restrictive, and those skilled in the art can make many forms under the inspiration of the present application without departing from the scope of the present application and the scope of protection of the claims.
