Abstract
Description
Technical Field
[0001] This utility model relates to the field of insulated louvered glass technology, specifically to an insulated glass window with built-in louvers. Background Technology
[0002] Built-in louvered insulated glass is an innovative product that combines traditional louvered blinds with insulated glass, saving the space required for traditional louvered blind installation while fulfilling the need for sun shading.
[0003] In related technologies, a search revealed a solution for an insulated glass unit with built-in louvers (publication number CN220378158U). By opening a through groove above the insulated glass unit and setting a sealing plate, the sealing plate can be disassembled when the internal louver mechanism malfunctions, thus facilitating maintenance and greatly improving maintenance efficiency.
[0004] However, in the above solution, removing the sealing plate only allows for maintenance of the upper part of the louver mechanism. If there is a problem in the middle or lower part of the louver, there is not enough operating space, making it difficult to inspect and replace the louver. Utility Model Content
[0005] The purpose of this invention is to provide a hollow glass window with built-in blinds to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a hollow glass window with built-in blinds, including a main frame, a first glass plate installed on the inner wall of the main frame through a first limiting member, and a louvered curtain installed inside the main frame;
[0007] The secondary frame is rotatably connected to the main frame. A second glass plate is installed inside the secondary frame through a second limiting member. The venetian blind is located between the first glass plate and the second glass plate, which serves to shade the sun. The first glass plate and the second glass plate also have sound insulation and heat insulation functions.
[0008] The locking component is connected to the main frame and the secondary frame, enabling a detachable connection between the main frame and the secondary frame. Removing the locking component allows the second glass panel to be rotated and opened, allowing for inspection of the venetian blinds.
[0009] Furthermore, a window frame is rotatably connected to the surface of the main frame, and a first hinge is installed between the window frame and the main frame, which can rotate to open the first glass panel and the second glass panel for ventilation.
[0010] Furthermore, a baffle is provided on the surface of the main frame, which limits the movement of the secondary frame. An adhesive strip is connected to the baffle, and the baffle contacts the adhesive strip to improve the sealing performance when the window is closed and to provide good limiting effect for the first and second glass panels.
[0011] Furthermore, a second hinge is installed between the secondary frame and the main frame, a handle is installed on the main frame, and a sealing ring is provided on the surface of the secondary frame to contact the main frame, thereby improving the sealing performance of the connection between the secondary frame and the main frame and providing good dust prevention.
[0012] Furthermore, the locking component includes a first screw, a screw hole, and a mounting groove. The screw hole and mounting groove are located on the main frame and the secondary frame. The first screw passes through the mounting groove and is screwed into the screw hole, making it convenient to open the second glass plate.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] (1) After unscrewing the second screw, the main frame and the secondary frame are in the open state. When the secondary frame is rotated, the second glass plate can be rotated. At this time, the second glass plate no longer blocks the blinds, realizing the maintenance and replacement of the blinds. The operating space is large and the inspection is convenient.
[0015] (2) The first and second glass panels rotate within the window frame along with the main frame and the secondary frame, making it easy to open for ventilation. The baffle and rubber strip can block the secondary frame and improve the sealing performance when the window is closed.
[0016] (3) A sealing ring is set between the main frame and the secondary frame to improve the sealing effect of the connection between the main frame and the secondary frame. This can play a certain role in dust and water prevention and has a good protective effect on the Venetian blinds. Attached Figure Description

Detailed Implementation
[0024] 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.
[0025] Example:
[0026] Please see Figure 1-6 This utility model provides a technical solution: a hollow glass window with built-in blinds, including a main frame 3, a first glass plate 5 installed on the inner wall of the main frame 3 by a first limiting member 12, and a venetian blind 9 installed inside the main frame 3, the venetian blind 9 being located between the first glass plate 5 and the second glass plate 7, the color of the venetian blind 9 can be set as needed to improve the decorative effect.
[0027] The secondary frame 10 is rotatably connected to the main frame 3. The second glass plate 7 is installed inside the secondary frame 10 through the second limiting member 17. The main frame 3 and the secondary frame 10 can be made of commonly used window frame plastic. The secondary frame 10 and the second glass plate 7 can be opened by rotation, and the entire Venetian blind 9 can be inspected with sufficient operating space.
[0028] The locking component is connected to the main frame 3 and the secondary frame 10, which can prevent the secondary frame 10 from rotating freely and also improve the sealing of the connection between the secondary frame 10 and the main frame 3.
[0029] In this embodiment, as Figure 1 As shown, a window frame 1 is rotatably connected to the surface of the main frame 3, which is fitted onto the main frame 3. The window frame 1 is installed on the wall and can be rotated to open the first glass panel 5 and the second glass panel 7 for ventilation.
[0030] In this embodiment, as Figure 1 As shown, a first hinge 2 is installed between the window frame 1 and the main frame 3. The first hinge 2 enables the window frame 1 and the main frame 3 to rotate and connect, making it flexible and convenient to open the main frame 3.
[0031] In this embodiment, as Figure 2 and Figure 3 As shown, a baffle 6 is provided on the surface of the main frame 3. The baffle 6 limits the sub-frame 10 to prevent the sub-frame 10 from rotating excessively and to ensure that the sub-frame 10 and the main frame 3 are inside the window frame 1. An adhesive strip 8 is connected to the baffle 6. The baffle 6 contacts the adhesive strip 8 to improve the sealing effect and play a role in dust and water prevention.
[0032] In this embodiment, as Figure 6 As shown, the first limiting member 12 and the second limiting member 17 are both connected to the main frame 3 and the secondary frame 10 respectively by the first screw 13. The first limiting member 12 is set in a right angle shape, and the second limiting member 17 is set in a straight strip shape. The second limiting member 17 is embedded in the secondary frame 10, which will not affect the adhesion between the secondary frame 10 and the main frame 3. Glass glue can also be used to reinforce the first glass plate 5 and the second glass plate 7 to prevent the first glass plate 5 and the second glass plate 7 from loosening.
[0033] In this embodiment, as Figure 5 As shown, a second hinge 11 is installed between the secondary frame 10 and the main frame 3, and a handle 4 is installed on the main frame 3. The second hinge 11 enables the rotational connection between the secondary frame 10 and the main frame 3, and the handle 4 facilitates the opening and closing of the main frame 3.
[0034] In this embodiment, as Figure 6 As shown, the surface of the secondary frame 10 is provided with a sealing ring 18 that contacts the main frame 3. The sealing ring 18 is clamped by the secondary frame 10 and the main frame 3, thereby improving the sealing performance of the connection between the main frame 3 and the secondary frame 10.
[0035] In this embodiment, as Figure 6 As shown, the locking component includes a first screw 13, a screw hole 14, and a mounting groove 15. The screw hole 14 and the mounting groove 15 are placed on the main frame 3 and the secondary frame 10. The first screw 13 passes through the mounting groove 15 and is screwed into the screw hole 14. The mounting groove 15 accommodates the first screw 13 to prevent the first screw 13 from protruding on the secondary frame 10.
[0036] Specifically, when in use, the window frame 1 is installed in the designated position, and common window locks can be set on the handle 4 and the window frame 1 to lock the window frame 1 and the main frame 3. The handle 4 is used to easily open the main frame 3, the first glass panel 5, and the second glass panel 7 for ventilation.
[0037] When inspecting the Venetian blind 9, first open the main frame 3, the first glass panel 5, and the second glass panel 7. Then loosen the second screw 16 to separate it from the main frame 3. After unscrewing all the second screws 16, the secondary frame 10 can be rotated and opened. The secondary frame 10 rotates around the center of the second hinge 11 and drives the second glass panel 7 to open. At this time, the Venetian blind 9, which is between the first glass panel 5 and the second glass panel 7, is no longer blocked by the second glass panel 7, making it convenient to inspect the entire Venetian blind 9.
[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
