Description

Technical Field

[0001] This utility model belongs to the field of insulating glass technology, and in particular relates to a roll-up type insulated glass with built-in blinds. Background Technology

[0002] In the field of architectural decoration, insulated glass is widely used due to its excellent heat insulation and sound insulation performance. Insulated glass with built-in blinds further expands the functions of light adjustment and sun shading, effectively improving the indoor comfort. However, existing insulated glass with built-in blinds still has many shortcomings in practical applications.

[0003] In detail, on the one hand, some products use fixed installation or flip-adjustment methods for their venetian blind structure. When the maximum light-gathering effect is required, the venetian blinds cannot be fully retracted, resulting in limited light transmittance of the glass and difficulty in meeting the lighting needs of special scenarios. On the other hand, existing roll-up venetian blind structures are prone to venetian blind misalignment and jamming during the rolling process, affecting the smoothness of use.

[0004] In summary, existing insulated glass units with built-in blinds have certain defects in structural design and functional implementation. There is an urgent need for a new type of retractable insulated glass unit with built-in blinds that can fully accommodate the blinds according to actual needs, ensure the light transmittance of the glass under special circumstances, and has the advantages of structural stability and smooth retraction. Utility Model Content

[0005] The purpose of this invention is to provide a retractable insulated glass unit with built-in venetian blinds, which addresses the problems of limited light transmission caused by the difficulty in fully retracting the venetian blinds and the tendency of retractable venetian blinds to shift or get stuck during the retraction process.

[0006] The present invention achieves the above objectives through the following technical solution: a retractable insulated glass with built-in louvers, comprising a window frame, two sets of glass arranged opposite each other on the inner wall of the window frame cavity, forming a vacuum environment between the two sets of glass, a louver assembly arranged between the two sets of glass, and a magnet cooperating with the louver assembly arranged at the bottom of the window frame cavity.

[0007] The venetian blind assembly includes bearings disposed opposite to each other on the two side walls of the window frame. A winding roller is rotatably disposed between the two sets of bearings. A winding motor for driving the winding roller is disposed at one of the bearings. A venetian blind is disposed on the winding roller. A counterweight is disposed at the bottom of the venetian blind. The counterweight cooperates with the magnet. Channel steel is disposed on both sides of the venetian blind to guide its winding direction. The channel steel is fixed to the inner wall of the window frame cavity.

[0008] Furthermore, the top of the window frame has a cavity for accommodating the winding roller, and the winding roller is placed horizontally within the cavity.

[0009] Furthermore, the venetian blind is composed of multiple blades, and adjacent blades are connected by flexible wires.

[0010] Furthermore, the counterweight is made of metal, and under the magnetic field of the magnet, the counterweight can respond quickly and cooperate stably with the magnet.

[0011] Furthermore, a smooth arc protrusion is provided on the top inner sidewall of the channel steel, and the arc protrusion matches the edge of the venetian blind.

[0012] Furthermore, two sets of rubber strips are provided opposite each other at the slotted part of the channel steel. When the venetian blind is rolled up, it is placed between the two sets of rubber strips, and the rubber strip located on the inner side is on the same vertical plane as the arc-shaped protruding end face.

[0013] Beneficial effects: This utility model has a reasonable design, simple and stable structure, and strong practicality, and has the following beneficial effects:

[0014] 1. Flexible light control: The blinds can be fully rolled up by driving the winding rollers with the winding motor. In special scenarios, the glass can be guaranteed to reach the maximum light transmittance, overcoming the problem of limited light transmittance caused by the difficulty of fully retracting the traditional blind structure, and meeting diverse lighting needs.

[0015] 2. Stable winding guidance: The channel steel set on both sides of the Venetian blind has a smooth arc protrusion on the inner side wall of its top that matches the edge of the Venetian blind. The two sets of rubber strips at the groove of the side wall play a limiting role when the Venetian blind is rolled up, effectively guiding the direction of the Venetian blind to roll up, avoiding deviation and jamming during the rolling process, and improving the smoothness of use.

[0016] 3. Reliable fixed positioning: The counterweight at the bottom of the Venetian blind cooperates with the magnet at the bottom of the window frame cavity. The counterweight is made of metal, which can respond quickly and be stably attracted under the magnetic field of the magnet, ensuring the tension of the Venetian blind after it is lowered.

[0022] 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.

[0023] Example 1:

[0024] Combination Figure 1-3 The retractable insulated glass unit with built-in louvers shown includes a rectangular frame 1, which is integrally formed from high-strength aluminum alloy. The inner wall of the frame 1 is precision-machined with a smooth surface for installing and fixing subsequent components. Two sets of glass 2 are arranged parallel to each other on the inner wall of the frame 1. The glass 2 is tempered glass with high strength and impact resistance. The two sets of glass 2 are sealed with a sealing strip to form a completely sealed vacuum environment. This vacuum environment can effectively block heat conduction and sound wave transmission, significantly improving the heat insulation and sound insulation performance of the glass. A louver assembly 3 is set in the hollow area between the two sets of glass 2. The louver assembly 3 is the core component for realizing the glass dimming function, and its operation directly affects the performance. At the same time, a magnet 4 is fixedly installed at the center of the bottom of the frame 1 cavity to cooperate with the louver assembly 3. The magnet 4 is used to attract the corresponding component at the bottom of the louver assembly 3 to achieve the positioning and fixing of the louver blind.

[0025] The venetian blind assembly 3 includes bearings 301 disposed opposite to the two side walls of the window frame 1. The axes of the two sets of bearings 301 are on the same horizontal line. A take-up roller 302 is horizontally rotatable between the two sets of bearings 301. The take-up roller 302 is a cylindrical metal body. A take-up motor 303, which drives the take-up roller 302 to rotate, is disposed outside one of the bearings 301. The take-up motor 303 is a miniature servo motor with precise control over speed and direction, and can stably drive the take-up roller 302 to rotate forward or backward. Venetian blinds 304 are evenly wound around the outer circumference of the take-up roller 302. Composed of multiple rectangular blades connected by flexible lines, the blinds 304 ensure effective rolling and maintain flatness when unfolded. A counterweight 305 is fixedly connected to the bottom of the blind 304. This counterweight ensures the blind 304 hangs naturally and remains flat when unfolded, and also responds quickly and adheres tightly to the magnetic field of the magnet 4, achieving stable positioning of the blind 304. Furthermore, channel steel 306 is provided on both sides of the blind 304 to guide its rolling direction. The channel steel 306 is fixed to both sides of the inner wall of the window frame 1 cavity with screws. The channel steel 306 limits and guides the edges of the blind 304, ensuring that the blind 304 maintains linear movement during rolling or unfolding, preventing deviation or jamming.

[0026] In this embodiment, a rectangular cavity larger than the size of the winding roller 302 is provided at the top of the window frame 1. The winding roller 302 is placed horizontally in the cavity, and its two ends are tightly engaged with the bearings 301 on the two side walls of the window frame 1 to ensure that the winding roller 302 maintains a stable horizontal state during rotation. The arrangement of the winding roller 302 in the cavity causes the center of gravity of the entire louver assembly 3 to shift upward, optimizing the internal structural layout of the insulated glass. At the same time, it avoids the winding roller 302 occupying the visible space between the glass panes. Under the premise of ensuring the normal winding function of the louver blind 304, the light transmission area of ​​the insulated glass is maximized.

[0027] In this embodiment, the counterweight 305 is made of metal material with a smooth and flat surface, which significantly enhances the adsorption effect with the magnet 4. Under the action of the magnetic field of the magnet 4, the counterweight 305 can respond quickly and move towards the magnet 4 in a very short time. When the two come into contact, a stable adsorption force is formed to ensure the verticality of the venetian blind 304 after it is lowered.

[0028] In this embodiment, a smooth arc protrusion 307 is integrally formed on the inner sidewall of the top of the channel steel 306. The arc of the arc protrusion 307 can form a smooth guide surface during the winding process of the Venetian blind 304. At the same time, the presence of the arc protrusion 307 can also play a certain role in protecting the edge of the Venetian blind 304, reducing wear during the winding process, and extending the service life of the Venetian blind 304.

[0029] In this embodiment, two sets of rubber strips 308 are arranged opposite each other at the slotted side wall of the channel steel 306. The two sets of rubber strips 308 are vertically parallel and the spacing is slightly larger than the thickness of the Venetian blind 304. This ensures that the Venetian blind 304 can be placed precisely between the two sets of rubber strips 308 when it is rolled up. The rubber strips 308, by virtue of their own material properties, constrain the Venetian blind 304, further enhancing the guiding effect and preventing the Venetian blind 304 from shifting left or right during the rolling process. It also reduces the wear of the Venetian blind 304. It is worth mentioning that the rubber strip 308 located on the inner side is on the same vertical plane as the end face of the arc protrusion 307. This design ensures that the Venetian blind 304 is always simultaneously guided by the curved surface of the arc protrusion 307 and laterally supported by the rubber strips 308 on the rolling path. The two work together to not only significantly improve the stability and smoothness of the Venetian blind 304 rolling, but also effectively eliminate the vibration and noise that may be generated during the rolling process, bringing users a quieter and more comfortable user experience.
