Description

Technical Field

[0001] This utility model belongs to the technical field of insulated glass windows, and relates to a glass window, particularly an insulated glass window with built-in roller blinds. Background Technology

[0002] Built-in shading insulated glass, as a modern building component that combines the functions of insulated glass and shading, not only possesses the advantages of insulated glass such as heat insulation, thermal insulation, and sound insulation, but also allows for flexible adjustment of light and shading effects. It mainly consists of an insulated glass base composed of glass and a frame, and a shading device located between the two glass panes. According to the type of built-in shading device, insulated glass with built-in roller blind mechanism can be divided into insulated glass with built-in pleated blind mechanism, insulated glass with built-in venetian blind mechanism, and insulated glass with built-in venetian blind mechanism. Taking insulated glass with built-in roller blind mechanism as an example, in addition to the insulated glass base, it also includes a roller blind mechanism, a suspension beam, a rewinding shaft, a tensioning mechanism, and a flipping mechanism. The tensioning mechanism and the flipping mechanism are used to realize the opening and closing of the roller blind mechanism. However, since the curtain is fixed with glue or nails, the curtain will fold when it is rolled up, thus affecting the shading effect.

[0003] To address the aforementioned issues, the prior art provides a glass window with a built-in roller blind mechanism. By setting a snap-fit ​​structure within the roller blind mechanism shaft and creating a gap inside for the roller blind mechanism fabric to extend into, the roller blind mechanism fabric is prevented from wrinkling during installation and from easily bending during retraction. Furthermore, in conjunction with a weight block, the roller blind mechanism fabric retraction and expansion are made smoother and more efficient, enhancing the light-blocking effect.

[0004] However, because it uses several snap-fit ​​structures to clamp the ends of the roller blind mechanism to fix the roller blind mechanism, it is difficult to ensure the consistency of the clamping height between different snap-fit ​​structures. In addition, due to the presence of weight blocks, the roller blind mechanism will have uneven stress during the snap-fit ​​process. After long-term use, wrinkles will be generated inside the double-glazed window after unfolding, affecting the appearance. Furthermore, when rolling up, the longer stretches will stack, which will increase the resistance during rolling up. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned problems in the existing technology by proposing a glass window with a built-in roller blind mechanism. The technical problem solved is how to improve the flatness of the curtain fabric and the stability during rolling.

[0006] The objective of this utility model can be achieved through the following technical solution: a hollow glass window with a built-in roller blind, comprising two glass panes and a frame, wherein the glass panes are arranged on the frame front and back and cooperate with the frame to form a hollow glass window, and a roller blind is provided between the two glass panes, wherein the roller blind includes a roller shaft and a suspension beam, and the roller shaft includes a drum, characterized in that a curtain is provided between the roller shaft and the suspension beam, and two clamping strips are respectively provided at the upper and lower ends of the curtain, the clamping strips being used to clamp the upper and lower end faces of the curtain, and both the roller shaft and the suspension beam are provided with movable cavities for accommodating the clamping strips, the movable cavities being connected to the outside through a connecting groove, the width of the connecting groove being smaller than the width of the clamping strips, and both the upper and lower ends of the curtain being able to pass through the connecting grooves located on the roller shaft and the suspension beam and connect with the clamping strips.

[0007] This application adds a roller blind mechanism to the existing central control window frame, using rollers and suspension beams at the top and bottom of the central curtain fabric. The curtain fabric is then unfolded and stretched between the rollers and suspension beams to achieve a light-blocking effect. The curtain fabric is then retracted by rotating the rollers. This application includes clamping strips at the top and bottom of the curtain fabric. Since the width of the clamping strips is greater than the width of the connecting groove, it prevents the top and bottom of the curtain fabric from detaching from the rollers and suspension beams during unfolding and winding. The clamping strips also limit the movement of the curtain fabric. Furthermore, since the suspension beams stretch the curtain fabric after unfolding, the clamping strips ensure uniform force during stretching. The clamping strips are positioned within the movable cavities of the rollers and suspension beams, allowing them to move radially. This ensures that even after prolonged use, the light-blocking portion of the curtain fabric remains flat and prevents the clamping strips from causing the curtain fabric to move to the left or right, thus improving the stability of the curtain fabric during unfolding.

[0008] In the aforementioned insulated glass window with built-in roller blinds, rolling brackets are fixed to both ends of the roller, and the clamping strip is located between the two rolling brackets. The rolling brackets improve stability during the rolling process.

[0009] In the aforementioned insulated glass window with built-in roller blinds, clamping portions are protruding from both the top and bottom ends of the curtain fabric. Clamping strips are clamped onto these clamping portions, and the length of the clamping strips is greater than or equal to the length of the clamping portions. By additionally providing protruding clamping portions, the clamping strips are prevented from directly clamping onto the curtain fabric, thus avoiding any impact on the curtain's unfolded state caused by wrinkles generated during clamping.

[0010] In the aforementioned insulated glass window with built-in roller blinds, a receiving groove is provided on the inner side of the frame, and the left and right sides of the curtain pass through the receiving groove and are connected to the suspension beam. By providing receiving grooves on the two inner side walls of the frame, the curtain can be smoothly unfolded while increasing the unfolded area of ​​the curtain. This prevents light leakage due to incomplete curtain coverage after the curtain tilts slightly, thus improving the user experience.

[0011] In the aforementioned insulated glass window with built-in roller blind, plugs are provided on both sides of the suspension beam. The two plugs are positioned opposite each other on one side to restrict the movement of the clamping member along the length of the suspension beam, and a limiting protrusion is provided on the other side of the plug to cooperate with the receiving groove.

[0012] In the aforementioned insulated glass window with built-in roller blind, a lifting mechanism is also provided inside the frame. The lifting mechanism is connected to one of the rolling supports and drives the roller to rotate.

[0013] In the aforementioned insulated glass window with built-in roller blinds, the clamping strip includes a protrusion and a groove, and the upper and lower ends of the curtain fabric are clamped in the groove and the protrusion.

[0014] Compared with the prior art, the insulated glass window with built-in roller blind provided by this utility model has the following advantages:

[0015] 1. This insulated glass window with built-in roller blind has additional protruding clamping parts at the upper and lower ends of the curtain fabric, and clamping strips of the same length as the clamping parts are used to fix it, so that the curtain fabric can be evenly stressed when unfolded, thereby ensuring the flatness of the curtain fabric after unfolding.

[0016] 2. In this insulated glass window with built-in roller blind, rolling brackets and end caps are respectively set on both sides of the roller and the suspension beam to prevent the clamping strips from moving the curtain fabric left and right along the length direction. By setting receiving grooves on the inside of the frame and on both sides of the end caps, front and back displacement is prevented. By limiting the displacement of the two clamping strips connected to the curtain fabric in the length direction, the possibility of wrinkles is reduced and the stability during the rolling process is improved.

[0023] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0024] like Figure 1 and Figure 2 As shown, this application includes a frame 1b and glass 1a disposed at the front and back of the frame 1b. The frame 1b includes short profiles 1b1 disposed vertically and long profiles 1b2 disposed horizontally. The long profiles 1b2 and short profiles 1b1 are connected by corner pieces 1b3. A roller shutter mechanism 2 is provided within the space enclosed by the frame 1b. Covers are provided on the front and back sides of the roller shutter mechanism 2.

[0025] 2. The cover plates 1b4 on both sides, wherein the roller blind mechanism 2 includes a roller 2a, a curtain 2c and a suspension beam 2b. The roller 2a, the curtain 2c and the suspension beam 2b are arranged in sequence from top to bottom. The left and right ends of the roller 2a are provided with rolling brackets 2a1. One of the rolling brackets 2a1 is connected to a lifting mechanism 2d by a lifting rope 2d2.

[0026] As for the lifting mechanism 2d, it includes a lifting handle 2d1 and a lifting rope 2d2. The lifting handle 2d1 includes a winding wheel and an inner drive frame. The inner drive frame is equipped with a drive magnet. The user places an iron block or a magnet outside the hollow glass window 1, so that it attracts the drive magnet on the inner drive frame, thereby driving the roller 2a to rotate through the lifting handle, lifting wheel and rolling bracket 2a1.

[0027] like Figure 3As shown, the roller blind mechanism 2 of this application consists of a roller 2a, a curtain 2c, and a suspension beam 2b. Rolling supports 2a1 are provided on both sides of the roller 2a, and plugs 2b1 are provided on both sides of the suspension beam 2b. Clamping portions 2c1 are provided at the upper and lower ends of the curtain 2c. A connecting groove 2f is provided on both the roller 2a and the suspension beam 2b. The connecting groove 2f allows the clamping portions 2c1 of the curtain 2c to pass through and enter the receiving cavity within the roller 2a and the suspension beam 2b. The rolling support 2a1 includes a roller and a rotating support for fixing the roller. A groove is provided on the rotating support to mate with the end of the roller. A limiting protrusion 2b1a is provided on one side of the plug 2b1.

[0028] like Figure 4 as well as Figure 5 As shown, a roller blind mechanism 2 is provided inside the frame 1b. The roller shaft 2a in the roller blind mechanism 2 is rotatably connected to the frame 1b on both sides via rolling brackets 2a1. An unfoldable curtain 2c is wound on the roller shaft 2a. A suspension beam 2b is fixed to the lower end of the curtain 2c. The suspension beam 2b cooperates with the roller shaft 2a to unfold the curtain 2c. The upper and lower ends of the curtain 2c are provided with clamping parts 2c 1 for fixing to the roller shaft 2a and the suspension beam 2b. Both the roller shaft 2a and the suspension beam 2b are hollow, forming a movable cavity 2e. A clamping strip 3 is provided inside the movable cavity 2e, and the clamping strip 3 can move radially within the movable cavity 2e. The roller shaft 2a and the suspension beam 2b are connected by the curtain 2c. The upper and lower ends of the curtain 2c are respectively provided with protruding clamping parts 2c 1. The clamping strip 3 includes a convex strip 3a and a groove 3b. 1 is sandwiched between the protrusion 3a and the groove 3b. A connecting groove 2f is opened on one side of the roller 2a for the curtain 2c to pass through. A connecting groove 2f is also opened at the upper end of the suspension beam 2b, so that the clamping part 2c 1 in the curtain 2c can enter the movable cavity 2e of the suspension beam 2b and communicate with the clamping strip 3. It is worth mentioning that the clamping strip 3 and the clamping part 2c 1 have the same length and width.

[0029] In addition, the rolling brackets 2a1 located at both ends of the roller 2a cooperate with each other to restrict the left and right movement of the clamping strip 3. The long profiles 1b2 located on the left and right sides of the frame 1b are provided with receiving grooves 1b2a. The two receiving grooves 1b2a are arranged opposite each other. The two sides of the suspension beam 2b are provided with plugs 2b1. One side of the two plugs 2b1 cooperates with the suspension beam 2b and is arranged opposite each other to restrict the left and right movement of the clamping strip 3 in the length direction. On the other side of the plugs 2b1, there are limiting protrusions 2b1a. The limiting protrusions 2b1a and the left and right ends of the curtain 2c are located in the receiving grooves 1b2a. One of the frames 1b is provided with a lifting handle 2d1. The lifting handle 2d1 is connected to the rolling bracket 2a1 at the top through a lifting rope 2d2.

[0030] In summary, this application, based on the existing insulated glass 1a, incorporates a roller blind mechanism 2 within the frame 1b. The roller 2a rotates via a lifting handle 2d1 and a lifting rope 2d2 within the frame 1b, thereby completing the winding and unwinding of the curtain 2c. The curtain 2c in this application has clamping portions 2c 1 at both its upper and lower ends. These clamping portions 2c 1 are secured by the engagement of protrusions 3a and grooves 3b on clamping strips 3 located within the roller 2a and suspension beam 2b, thereby fixing the curtain 2c. 1. The length of the clamping strip 3 is the same as that of the curtain 2c. Therefore, it can ensure that the curtain 2c is subjected to uniform force when it is unfolded, thereby avoiding uneven force caused by local clamping and fixing of the curtain 2c. This ensures the flatness of the curtain 2c during long-term use. Furthermore, by setting the clamping strip 3 in the movable cavity 2e with a certain amount of room for movement, the error generated during the cutting of the curtain 2c is reduced, and excess curtain 2c is prevented from accumulating within the visible range of the hollow glass window 1, thus improving the stability during the unfolding process.

[0031] In addition, this application also provides receiving grooves 1b2a on both sides of the frame 1b. The receiving grooves 1b2a restrict the limiting protrusions 2b1a on the end cap 2b1, thereby preventing the suspension beam 2b from shaking during the unfolding and rewinding of the curtain 2c, ensuring the smoothness and stability of the curtain 2c during unfolding. Both sides of the curtain 2c are located within the receiving grooves 1b2a, thereby increasing the area of ​​the curtain 2c after unfolding, thus increasing the light-blocking area. The cooperation between the receiving grooves 1b2a and the end cap 2b1 guides the curtain 2c, preventing the curtain 2c from shaking back and forth in the middle during unfolding, thereby improving the stability of the curtain 2c during unfolding and avoiding wrinkles caused by accumulation.
