Description

Technical Field

[0001] This utility model belongs to the field of window technology, specifically relating to blinds, and more particularly to heat-insulating blinds with anti-aging structures. Background Technology

[0002] Insulating glass louvers are widely used in building curtain walls and interior decoration due to their advantages such as sound insulation, heat insulation and aesthetics; their louvers are usually adjusted by pulling rope or magnetic control mechanism.

[0003] In related technologies, the louvers are usually made of aluminum alloy or PVC. Aluminum alloy louvers conduct heat quickly and expand significantly at high temperatures, making the area around the pull cord hole prone to deformation, which can lead to louver misalignment. PVC louvers soften after prolonged exposure to sunlight, and the edges of the pull cord hole crack or expand due to mechanical stress. However, under high-temperature exposure, the pull cord hole area of ​​the louvers is prone to deformation. The deformed pull cord hole increases friction, leading to wear, jamming, or even breakage of the pull cord. The louvers do not close tightly, affecting light blocking and aesthetics.

[0004] Therefore, how to avoid blade deformation is a technical problem that urgently needs to be solved in this field.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore, the above description is not considered to constitute prior art information. Utility Model Content

[0008] In one optional embodiment, the point support ring includes: a reinforcing ring fixed to the louver, a flexible ring located on the outer periphery of the reinforcing ring, and a through hole penetrating both; the thickness of the flexible ring gradually decreases from the center to the edge; the radius of the through hole is smaller than the radius of the pull rope hole.

[0009] In one alternative embodiment, the arc-shaped convex surface and the arc-shaped concave surface are evenly distributed with cross-arranged T-shaped ribs.

[0010] In one optional embodiment, the inner side of the protective inner frame is provided with a V-shaped mounting groove, and an elastic strip is embedded in the V-shaped mounting groove, which is adapted to abut against the edge of the glass.

[0011] In one optional embodiment, the bottom of the vacuum chamber is provided with a getter storage box, which is filled with a composite adsorbent of molecular sieve and calcium oxide, and its volume is 0.3%-0.5% of the vacuum chamber volume.

[0012] Secondly, this disclosure also provides a heat-insulating louver with an anti-aging structure, comprising: an outer frame and a protective inner frame disposed therein, wherein double-layered glass is installed on the protective inner frame to form a vacuum cavity; a pull cord structure and a plurality of louvers that can be rolled up and down in the vacuum cavity via the pull cord structure, wherein the louvers are provided with pull cord holes; the louvers have an arc-shaped convex surface and an arc-shaped concave surface, wherein the arc-shaped convex surface and the arc-shaped concave surface are evenly distributed with cross-arranged T-shaped ribs.

[0016] In one optional embodiment, the bottom of the vacuum chamber is provided with a getter storage box, which is filled with a composite adsorbent of molecular sieve and calcium oxide, and its volume is 0.3%-0.5% of the vacuum chamber volume.

[0017] The beneficial effects of this utility model are that it provides a heat-insulating louver with an anti-aging structure. By setting an outer frame and a protective inner frame, a double-layer frame structure is formed, which improves the overall strength, reduces deformation caused by external force or temperature changes, and ensures the airtightness of the double-layer glass.

[0037] Research has revealed the shortcomings of existing technologies: Insulating glass louvers are widely used in building curtain walls and interior decoration due to their advantages such as sound insulation, heat insulation, and aesthetics; their louvers are usually adjusted for opening and closing by pull ropes or magnetic control mechanisms.

[0038] In related technologies, the louvers are usually made of aluminum alloy or PVC. Aluminum alloy louvers conduct heat quickly and expand significantly at high temperatures, making the area around the pull cord hole prone to deformation, which can lead to louver misalignment. PVC louvers soften after prolonged exposure to sunlight, and the edges of the pull cord hole crack or expand due to mechanical stress. However, under high-temperature exposure, the pull cord hole area of ​​the louvers is prone to deformation. The deformed pull cord hole increases friction, leading to wear, jamming, or even breakage of the pull cord. The louvers do not close tightly, affecting light blocking and aesthetics.

[0039] Therefore, how to avoid blade deformation is a technical problem that urgently needs to be solved in this field.

[0040] The shortcomings of the above solutions are the result of the utility model inventor's practice and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this disclosure should be considered as contributions made by the utility model inventor to this disclosure.

[0041] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0042] The following detailed description, with reference to the accompanying drawings, describes some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0043] like Figures 1 to 3 As shown, some embodiments provide thermally insulated louvers with anti-aging structures, including: an outer structural frame 1 and a protective inner frame 2 disposed inside it, with double-glazed glass 3 installed on the protective inner frame 2 to form a vacuum cavity 4; the outer structural frame 1 is an integral support frame, with the protective inner frame 2 nested inside, and the double-glazed glass 3 installed on the protective inner frame 2 to form a vacuum cavity 4; the outer structural frame 1 is an integral support frame, with the protective inner frame 2 nested inside, and the double-glazed glass 3 installed on the protective inner frame 2 to form a vacuum cavity 4; the protective inner frame 2 serves as a mounting base for the glass 3, preventing the glass 3 from directly contacting the outer frame, reducing heat conduction, improving thermal insulation performance; enhancing the structure's resistance to deformation, ensuring the long-term sealing of the double-glazed glass 3, reducing thermal bridging effects, and improving energy-saving performance.

[0044] The structure includes a pull rope structure 5 and multiple louvers 6 that can be rolled up and down within the vacuum chamber 4 via the pull rope structure. Each louver 6 has a pull rope hole 63. Flexible ropes or metal wires are used, and the lifting and lowering of the louvers 6 are achieved through pulleys or guide grooves.

[0045] The louver 6 has an arc-shaped convex surface 61 and an arc-shaped concave surface 62. Since the pull rope hole 63 is a force-bearing point, it needs to withstand long-term friction and tension. A support ring 64 is provided on the outer periphery of the pull rope hole 63 on the arc-shaped concave surface 62. By setting the support ring 64, the pull rope hole 63 is prevented from deforming due to long-term force, thus extending its service life. The pull rope wear is reduced, ensuring smooth lifting and lowering of the louver 6.

[0046] Specifically, the support ring 64 includes: a reinforcing ring 642 fixedly connected to the louver 6; the reinforcing ring 642, such as stainless steel with a rubber layer covering its surface, provides rigid support and prevents deformation of the pull rope hole 63; a flexible ring 643 located on the outer periphery of the reinforcing ring 642; and a through hole 641 penetrating both; the thickness of the flexible ring 643 gradually decreases from the center to the edge; as a preferred embodiment, the flexible ring 643, such as silicone rubber, buffers pull rope friction and has a gradually changing thickness design (thick at the center and thin at the edge, which can disperse stress); the radius of the through hole 641 is smaller than the radius of the pull rope hole 63.

[0047] The curved convex surface 61 and the curved concave surface 62 are evenly distributed with cross-arranged T-shaped ribs 65; the vertical ribs of the T-shaped ribs 65 enhance the bending strength, and the transverse ribs improve the torsional performance; the cross arrangement forms a mesh support structure, which improves the overall stiffness of the louver 6.

[0048] The inner side of the protective inner frame 2 is provided with a V-shaped mounting groove 21, and an elastic strip is embedded in the V-shaped mounting groove 21, which is suitable for abutting against the edge of the glass 3; the V-shaped mounting groove 21 provides a guiding function to facilitate the installation and positioning of the glass 3; the elastic strip (such as EPDM rubber) buffers the vibration and thermal expansion and contraction of the glass 3, preventing hard contact from causing breakage; improves the sealing and shock resistance of the glass 3 installation; reduces stress concentration at the edge of the glass 3, and reduces the risk of spontaneous explosion.

[0049] The vacuum chamber 4 has a getter storage box 7 at the bottom, which is filled with a composite adsorbent of molecular sieve and calcium oxide. The opening of the getter storage box 7 is connected to the vacuum chamber 4, and its volume is 0.3%-0.5% of the volume of the vacuum chamber 4. The molecular sieve in the getter storage box 7 adsorbs moisture, and the calcium oxide absorbs gases such as CO2, maintaining a low humidity and low pressure environment in the vacuum chamber 4. The volume ratio (0.3%-0.5%) ensures adsorption efficiency while avoiding excessive space occupation; it prevents fogging or condensation in the vacuum chamber 4, maintains the light transmittance of the glass, and extends the service life of the double-layer glass 3.

[0050] Some embodiments provide a heat-insulating louver with an anti-aging structure, including: an outer frame 1 and a protective inner frame 2 disposed therein, the protective inner frame 2 being fitted with double-glazed glass 3 to form a vacuum cavity 4; a pull cord structure 5 and a plurality of louver blades 6 that can be rolled up and down within the vacuum cavity 4 via the pull cord structure, the louver blades 6 being provided with pull cord holes 63; the louver blades 6 having an arcuate convex surface 61 and an arcuate concave surface 62, the arcuate convex surface 61 and the arcuate concave surface 62 being evenly distributed with cross-arranged T-shaped ribs 65.

[0051] A support ring 64 is provided on the outer periphery of the drawstring hole 63 on the arc-shaped concave surface 62. The support ring 64 includes: a reinforcing ring 642 fixedly connected to the louver 6, a flexible ring 643 located on the outer periphery of the reinforcing ring 642, and a through hole 641 passing through both; the thickness of the flexible ring 643 gradually decreases from the center to the edge; the radius of the through hole 641 is smaller than the radius of the drawstring hole 63.

[0052] The inner side of the protective inner frame 2 is provided with a V-shaped mounting groove 21, and an elastic strip is embedded in the V-shaped mounting groove 21, which is suitable for abutting against the edge of the glass 3.

[0053] The bottom of the vacuum chamber 4 is equipped with a getter storage box 7, which is filled with a composite adsorbent of molecular sieve and calcium oxide, and its volume is 0.3%-0.5% of the volume of the vacuum chamber 4.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0055] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and 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, and therefore should not be construed as a limitation of this utility model.

Therefore, without departing from the teachings of the exemplary embodiments, the first element, component, region, layer, or segment discussed above may be referred to as the second element, component, region, layer, or segment.

[0056] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
