Description

Technical Field

[0001] This utility model relates to the field of glass window technology, and in particular to a triple-glazed, double-cavity insulated glass with built-in blinds. Background Technology

[0002] Against the backdrop of continuously upgrading global demands for building energy conservation, insulated glass, as an integrated high-performance architectural glass, has become a key component of modern building doors, windows, and curtain wall systems. Based on parallel arranged glass, it forms independent hollow cavities between the glass panes through a high-strength, high-airtightness composite adhesive, spacer frame, and sealant, creating a multi-layer barrier structure. This significantly improves the heat insulation effect of the building envelope while meeting the needs for indoor lighting and comfort control, making it an important material for achieving low-energy building operation.

[0003] A search revealed Chinese patent publication number CN201679424U, which discloses a single-handle, double-control venetian blind. This utility model features adjustable venetians arranged horizontally within the window frame. A drive shaft is positioned on the window frame at the upper horizontal end of the adjustable venetians. Symmetrically arranged at both ends of the drive shaft are a mechanism fixing foot, a venetian blind winder, a transmission gear, and a corner fixing foot. The drive shaft is connected to the venetian blind winder via the mechanism fixing foot, and the venetian blind winder is connected to the corner fixing foot via the transmission gear. A timing belt, an inner handle, and an outer handle are arranged sequentially from top to bottom on the window frame outside the corner fixing foot. The transmission rope, lower fixed foot, and spring are connected in series from top to bottom; a protrusion perpendicular to the adjustable louvers is set on the window frame corresponding to the inner handle, and the outer handle matching the inner handle is inserted into the protrusion. This utility model achieves the purpose of simple installation, cost saving, and saving indoor space. However, in actual use, in order to enhance the sound insulation and energy saving effect, a triple-glass design is adopted, which increases the distance between the inner magnetic handle and the outer magnetic handle, weakens the magnetic attraction force, and causes the outer magnet to be unable to effectively attract the inner magnet and transmit sufficient power, resulting in the louvers getting stuck and failing when closing and opening. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a triple-glazed, double-cavity hollow glass with built-in louvers, which aims to improve the problem in the prior art where the increased distance between the inner and outer magnetic handles weakens the magnetic attraction force, causing the outer magnet to be unable to effectively attract the inner magnet and transmit sufficient power, resulting in the louvers becoming stuck and failing when closing and opening.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a triple-glazed, double-cavity insulated glass unit with built-in blinds, comprising a frame, an interior glass and a middle glass installed on the front side of the frame, an exterior glass installed on the rear side of the frame, a venetian blind between the middle glass and the exterior glass, a pull cord threaded from the bottom upwards through the venetian blind, a pivot on the upper part of the frame, a rope drum installed on the pivot, the pull cord of the venetian blind wound around the rope drum, an inner magnetic handle connected to the distal end of the pull cord, a cover plate fixedly connected to the front side of the frame, a middle handle between the middle glass and the interior glass, a handle rail fixedly connected to the front side of the interior glass, an interior handle slidably connected to the outer wall of the handle rail, and the inner magnetic handle, the middle handle, and the interior handle are all magnetically attracted to each other.

[0006] As a further description of the above technical solution:

[0007] A spacer frame is fixedly connected between the interior glass and the intermediate glass. A first butyl rubber layer is provided on the front and back sides of the spacer frame. Both the interior glass and the intermediate glass are fixedly connected to the spacer frame through the first butyl rubber layer.

[0008] As a further description of the above technical solution:

[0009] A second butyl rubber layer is provided between the frame and the outdoor glass, and the frame and the outdoor glass are fixedly connected by the second butyl rubber layer.

[0010] As a further description of the above technical solution:

[0011] A first silicone sealant layer is provided on the outer side of the partition frame. The first silicone sealant layer is tightly bonded to the indoor glass and the intermediate glass to form a sealed structure. A second silicone sealant layer is provided on the outer side of the frame. The second silicone sealant layer is tightly bonded to the intermediate glass and the outdoor glass.

[0012] As a further description of the above technical solution:

[0013] A desiccant is provided on the left side of the inner wall of the frame, and the desiccant is embedded inside the frame.

[0014] As a further description of the above technical solution:

[0015] The outer walls of the inner magnetic handle, the middle handle, and the interior handle are all smoothed, and the inner magnetic handle, the middle handle, and the interior handle are all made of strong magnetic material.

[0016] This utility model has the following beneficial effects:

[0017] In this invention, the sliding connection between the indoor handle and the handle rail, as well as the magnetic attraction between the indoor handle, the middle handle, and the inner magnetic handle, enables smooth control of the venetian blind slat angle. The movement of the indoor handle drives the middle handle, which in turn drives the inner magnetic handle, ultimately pulling the venetian blind cord. This improves upon the problem in the prior art where the increased distance between the inner and outer magnetic handles weakens the magnetic attraction, resulting in insufficient power transmission and causing the venetian blinds to jam or fail when closing and opening. This effectively ensures the smoothness and reliability of the venetian blind operation. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Reference Figure 2 , Figure 3 and Figure 4 A triple-glazed, double-cavity insulated glass unit with built-in blinds includes a frame 1, which serves as the supporting structure for the entire insulated glass unit, bearing and fixing other components. An interior glass 2 and a middle glass 3 are installed on the front side of the frame 1. The interior glass 2 provides protection and visual obstruction for the interior. The middle glass 3, together with the interior glass 2 and the exterior glass 4, forms a triple-glazed, double-cavity structure, enhancing sound insulation and heat insulation performance. An exterior glass 4 is installed on the rear side of the frame 1 for protection from the outside, blocking external environmental factors from affecting the interior. A venetian blind 5 is installed between the middle glass 3 and the exterior glass 4. The venetian blind 5 can be of the Gagaku brand, model A0001. A pull cord 17 is threaded from the bottom upwards through the venetian blind 5. A pivot 18 is located at the top of the frame 1, and a rope drum 19 is installed on the pivot 18. The pull cord 17 of the venetian blind 5 is wound around the rope drum 19. The distal end of the pull cord 17 is connected to an inner magnetic handle 7, which interacts with the middle handle 8 and the interior handle 10 through magnetic force to transmit power. The blind 5 is operated by a cover plate 6 fixedly connected to the front side of the frame 1, which protects the internal structure of the front side of the frame 1 and prevents the exposed parts from being damaged. A middle handle 8 is set between the middle glass 3 and the interior glass 2. The middle handle 8 is attracted by the magnetism of the interior handle 10 and the inner magnetic handle 7 to transmit the operating power between them. A handle rail 9 is fixedly connected to the front side of the interior glass 2. The handle rail 9 provides a sliding track for the interior handle 10 to ensure its smooth movement. The interior handle 10 is for the operator to grip. By sliding on the handle rail 9, the entire magnetic transmission system is activated to control the blind 5. The interior handle 10 is slidably connected to the outer wall of the handle rail 9. The inner magnetic handle 7, the middle handle 8 and the interior handle 10 are all magnetically attracted. This magnetic attraction relationship realizes the stable transmission of power between the handles and solves the defect of insufficient power transmission caused by the spacing problem of traditional inner and outer magnetic handles.

[0028] Specifically, frame 1 serves as the overall supporting structure, with interior glass 2 and middle glass 3 installed on the front, and exterior glass 4 installed on the rear, forming a triple-glazed, double-cavity structure that provides sound insulation and heat insulation. The Venetian blinds 5 inside frame 1 are used to control their state, and their pull cord 17 is connected to the inner magnetic handle 7. A cover plate 6 fixed to the front of frame 1 protects the internal structure. A middle handle 8 is positioned between the middle glass 3 and the interior glass 2, working in conjunction with a handle rail 9 fixed to the front of the interior glass 2 and a slidingly connected interior handle 10. Through the magnetic attraction between the inner magnetic handle 7, the middle handle 8, and the interior handle 10, when the interior handle 10 is pulled along the handle rail 9, the middle handle 8 and the inner magnetic handle 7 move sequentially, thereby controlling the Venetian blinds 5 and allowing for their opening, closing, or angle adjustment.

[0029] Reference Figure 1 , Figure 2 and Figure 5 A spacer frame 11 is fixedly connected between the interior glass 2 and the intermediate glass 3, serving to separate the interior glass 2 and the intermediate glass 3, while also providing support to ensure the stability of the triple-glazed, double-cavity structure. A first butyl adhesive layer 12 is provided on the front and back sides of the spacer frame 11. The first butyl adhesive layer 12 has good adhesion and can firmly connect the interior glass 2 and the intermediate glass 3 to the spacer frame 11, enhancing the airtightness of the structure. Both the interior glass 2 and the intermediate glass 3 are fixedly connected to the spacer frame 11 through the first butyl adhesive layer 12, effectively preventing water vapor and air penetration and improving the heat insulation and sound insulation performance of the insulating glass. A second butyl adhesive layer 13 is provided between the frame 1 and the exterior glass 4. The second butyl adhesive layer 13 also plays an adhesive role, used to tightly connect the frame 1 and the exterior glass 4. The frame 1 and the exterior glass 4 are fixedly connected through the second butyl adhesive layer 13, making the frame 1 and the exterior glass 4 form a whole, further enhancing the stability and airtightness of the entire insulating glass structure and resisting the influence of the external environment on the internal structure of the glass.

[0030] Specifically, the interior glass 2 and the intermediate glass 3 are fixedly connected by a spacer frame 11 and a first butyl adhesive layer 12. The spacer frame 11 serves as a partition and support, and the first butyl adhesive layer 12 fills the front and rear sides of the spacer frame 11, ensuring a tight connection between the interior glass 2, the intermediate glass 3, and the spacer frame 11, thus guaranteeing structural stability and sealing in this area. The frame 1 and the exterior glass 4 are fixed by a second butyl adhesive layer 13, which firmly bonds the frame 1 and the exterior glass 4, enhancing overall sealing, preventing moisture intrusion, and ensuring the good performance of the triple-glazed, double-cavity insulated glass with built-in blinds.

[0031] Reference Figure 2 , Figure 3 and Figure 6 A first silicone sealant layer 14 is provided on the outer side of the spacer frame 11 to further seal the gap between the spacer frame 11 and the interior glass 2 and the intermediate glass 3. The first silicone sealant layer 14 is tightly bonded to the interior glass 2 and the intermediate glass 3 to form a sealed structure. The tight bonding enhances the sealing effect and prevents external substances such as water vapor and dust from entering the interior of the insulated glass. This sealed structure helps to maintain the stability of the internal environment of the insulated glass and improves the heat insulation and sound insulation performance. A second silicone sealant layer 15 is provided on the outer side of the frame 1 to strengthen the sealing between the frame 1 and the intermediate glass 3 and the exterior glass 4. The second silicone sealant layer 15 is tightly bonded to the intermediate glass 3 and the exterior glass 4 to effectively block the interference of external environmental factors on the interior of the insulated glass and ensure the stability of the overall performance of the insulated glass.

[0032] Specifically, the first silicone sealant layer 14 on the outside of the spacer frame 11 is tightly bonded to the interior glass 2 and the intermediate glass 3, enhancing the sealing effect between the interior glass 2 and the intermediate glass 3, preventing moisture and dust from entering, and ensuring a stable internal environment for the insulated glass. The second silicone sealant layer 15 on the outside of the frame 1 is tightly bonded to the intermediate glass 3 and the exterior glass 4, further improving the overall sealing performance, enhancing the sound insulation and heat insulation performance of the glass, and ensuring the functional integrity of the triple-glazed, double-cavity structure.

[0033] Reference Figure 1 , Figure 2 and Figure 4 A desiccant 16 is installed on the left side of the inner wall of the frame 1 to absorb moisture inside the insulating glass. The desiccant 16 is embedded inside the frame 1, so that it exists stably inside the frame 1 and continues to play a moisture-proof role, preventing the light transmission and heat insulation performance from being affected by moisture condensation inside the glass. The outer walls of the inner magnetic handle 7, the middle handle 8 and the indoor handle 10 are all smoothed to reduce the friction between the hand and the handle during operation, making it smoother for the operator to pull the handle and improving the operating experience. The inner magnetic handle 7, the middle handle 8 and the indoor handle 10 are all made of strong magnetic materials, using AlNiCo permanent magnet alloy. The strong magnetic material ensures that there is a sufficiently strong magnetic attraction between the inner magnetic handle 7, the middle handle 8 and the indoor handle 10, so that the power can be reliably transmitted and the stable operation of the Venetian blind 5 can be ensured.

[0034] Specifically, the desiccant 16 embedded in the left side of the inner wall of frame 1 absorbs moisture that may be present inside the insulated glass, preventing fogging and maintaining good light transmission and heat insulation performance. The inner magnetic handle 7, the middle handle 8, and the interior handle 10 are made of strong magnetic material to ensure sufficient magnetic attraction to transmit operating power. At the same time, their smooth outer walls provide a comfortable feel during operation, reduce friction wear, and extend the service life of the components.

[0035] Working principle: During use, the operator pulls the indoor handle 10. Since the indoor handle 10 is slidably connected to the handle rail 9, it can move smoothly up and down on the handle rail 9. During the movement, the indoor handle 10 uses the pre-designed magnetic attraction between itself and the middle handle 8 to drive the middle handle 8 to move up and down synchronously within the space between the indoor glass 2 and the middle glass 3. The middle handle 8 is also magnetically attracted to the inner magnetic handle 7. When the middle handle 8 moves, it also drives the inner magnetic handle 7 to move up and down by magnetic force. The inner magnetic handle 7 is connected to the pull cord 17 of the Venetian blind 5, so the movement of the inner magnetic handle 7 will drive the pull cord 17 to move up and down. The pull cord 17 of the Venetian blind 5 pulls the slats, thereby controlling the flip angle of the slats on the Venetian blind 5 and achieving the closing or opening action of the Venetian blind 5. Through this interlocking and stable magnetic transmission method, insufficient power transmission caused by the distance between the inner and outer magnetic handles is avoided, ensuring the smoothness and reliability of the operation of the Venetian blind 5.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
