Description

Technical Field

[0001] This application relates to the field of glass windows, and in particular to a double-glazed window structure and an assembly method thereof. Background Art

[0002] With the continuous development of residential decoration, in order to improve the indoor comfort, people use double-glazed windows. The double-glazed window is composed of an inner and an outer layer of glass, and there is an air layer in the middle, which can play a good role in sound insulation and heat preservation. When installing the existing double-glazed window, first install the double-glazed glass on the window frame, seal the periphery of the double-glazed glass with sealant, and then inject argon gas between the double-glazed glasses. When the double-glazed window is used for a long time, the sealant is likely to fall off, and the argon gas inside the double-glazed glass will leak, affecting the sound insulation and heat preservation effect of the double-glazed window. Summary of the Invention

[0003] In order to improve the sealing effect of the double-sealed window and reduce the possibility of argon gas leakage in the double-sealed window, this application provides a double-glazed window structure and an assembly method thereof.

[0004] On the one hand, a double-glazed window structure provided by this application adopts the following technical solution:

[0005] A double-glazed window structure includes a window frame, and further includes a mounting frame provided on the window frame, a first glass and a second glass provided on the mounting frame. A first positioning block is provided along the shape of the mounting frame on the side wall of the first glass in contact with the mounting frame, and a second positioning block is provided along the shape of the mounting frame on the side wall of the second glass in contact with the mounting frame. The mounting frame includes an upper frame, a lower frame and side frames provided at both ends of the upper frame. The side frames are used to connect the upper frame and the lower frame, and a sealing assembly for positioning the first glass and the second glass is provided on the side frames.

[0006] By adopting the above technical solution, the window frame is installed in the window opening, the first glass and the second glass are installed in the mounting frame, and the mounting frame is installed in the window frame. The upper frame, the lower frame and the two side frames position the first glass and the second glass, and at the same time form an argon gas storage space. The first positioning block is used to improve the connection tightness between the first glass and the mounting frame, the second positioning block is used to improve the connection tightness between the second glass and the mounting frame, and the sealing assembly is used to improve the stability of the first glass and the second glass on the side frames. The sealing assembly is used to block the gap between the first glass or the second glass and the side frame, improving the sealing effect of the side frame.

[0007] Preferably, the sealing assembly includes positioning plates disposed within the side frame and on both sides of the glass 1 or the glass 2 in the length direction, a sealing strip disposed on the side of the positioning plate in contact with the glass 1 or the glass 2, and a sealing block disposed on the other side of the positioning plate. The side frame is provided with an embedding groove 1 for positioning the glass 1 and the glass 2 along the length direction, and the side frame is provided with a mounting groove 1 communicating with the embedding groove 1 along the length direction, and the mounting groove 1 is used for positioning the sealing strip.

[0008] By adopting the above technical solution, the positioning plate improves the stability of the sealing strip in the mounting groove 1. The sealing block is used to squeeze the positioning plate and push the positioning plate towards the glass 1 or the glass 2, facilitating the sealing strip to closely adhere to the glass 1 or the glass 2 and improving the sealing effect of the sealing strip. The embedding groove 1 is used to improve the stability of the glass 1 and the glass 2, facilitating the sealing assembly to fill the gap between the glass 1 or the glass 2 and the side frame.

[0009] Preferably, the sealing strip is made of an elastic material. The thickness of the sealing strip is greater than the thickness of the mounting groove 1. The width of the positioning plate is wider than the width of the sealing strip. The side frame is provided with a mounting groove 2 for positioning the positioning plate along the length direction. On the side of the positioning plate for mounting the sealing strip, fixing blocks are provided on both sides of the sealing strip along the length direction, and the side frame is provided with a fixing groove 1 adapted to the fixing blocks.

[0010] By adopting the above technical solution, the sealing strip is made of an elastic material, which facilitates the sealing strip to better adhere to the glass 1 or the glass 2. The thickness of the sealing strip is greater than the thickness of the mounting groove 1, and the positioning plate can push the sealing strip into the mounting groove 1, enabling the sealing strip to closely adhere to the glass 1 or the glass 2. The mounting groove 2 is used for positioning the positioning plate, and the fixing blocks and the fixing groove 1 improve the stability of the positioning plate on the side frame, facilitating the improvement of the sealing effect of the sealing strip on the glass 1 or the glass 2.

[0011] Preferably, the cross-section of the sealing block is convex. The narrower side of the sealing block is in close contact with the positioning plate, and the width of the narrower side of the sealing block is the same as the width of the positioning plate. The side frame is provided with a mounting groove 3 for positioning the sealing block along the length direction.

[0012] By adopting the above technical solution, the cross-section of the sealing block is convex. When the sealing block enters the mounting groove 3, it will push the positioning plate towards the sealing strip, improving the tightness between the sealing strip and the glass 1 or the glass 2. The width of the narrower side of the sealing block is the same as the width of the positioning plate, facilitating the sealing block to push the positioning plate to move. At the same time, when the sealing block does not enter the mounting groove 3, a part of the positioning plate will be located in the mounting groove 3 due to the thickness of the sealing strip.

[0013] Preferably, the upper frame and the lower frame have the same structure. An embedding groove two for positioning the first glass and the second glass is provided along the length direction on the bottom surface of the upper frame. Plug-in grooves one for the upper frame to be inserted into are provided at both ends of the side frame. Plug-in blocks one are provided at both ends of the upper frame and are located within the plug-in grooves one. One end of the plug-in block one is located on the side of the first glass away from the second glass, and the other end of the plug-in block one is located on the side of the second glass away from the first glass.

[0014] By adopting the above technical solution, the upper frame and the lower frame have the same structure, which is convenient for processing the upper frame and the lower frame, and is also convenient for installers to install, effectively reducing the possibility of installation confusion. The embedding groove two improves the stability of the first glass and the second glass within the upper frame. The plug-in groove one and the plug-in block one are used for the side frame to be plugged onto the upper frame, improving the stability of the upper frame and the side frame. One end of the plug-in block one is located on the side of the first glass away from the second glass, and the other end of the plug-in block one is located on the side of the second glass away from the first glass. The plug-in block surrounds the space area formed between the first glass and the second glass, improving the connection stability and sealing performance between the upper frame and the side frame.

[0015] Preferably, a fixing plate located between the first glass and the second glass is provided on the bottom surface of the upper frame. A fixing groove two adapted to the fixing plate is provided at the upper end of the side frame.

[0016] By adopting the above technical solution, the fixing plate and the fixing groove two improve the contact tightness between the upper frame and the top surfaces of the first glass and the second glass, reducing the possibility of bulging on the top surface of the upper frame and improving the sealing performance of the space formed by the first glass and the second glass.

[0017] Preferably, a positioning groove one for positioning the first positioning block and the second positioning block is provided along the length direction on the top surface of the upper frame. A positioning groove two for positioning the first positioning block and the second positioning block is provided along the length direction on the side frame.

[0018] By adopting the above technical solution, the positioning groove one is used for the upper frame to position the first positioning block and the second positioning block, and the positioning groove two is used for the side frame to position the first positioning block and the second positioning block, improving the positioning effect of the first positioning block and the second positioning block. The first positioning block and the second positioning block are used to cut off the connection gap between the upper frame or the side frame and the first glass and the second glass, further preventing the possibility of argon leakage.

[0019] Preferably, an air inlet hole communicating with the space formed by the first glass and the second glass is provided on the top surface of the upper frame. An elastic sealing sheet is provided around the inner wall of the air inlet hole. The elastic sealing sheet is in a circular ring shape, and an adhesive member is provided on the outer side wall of the elastic sealing sheet.

[0020] By adopting the above technical solution, the air inlet is used to blow argon gas into the space formed by the first glass and the second glass. The elastic sealing sheet is used to seal the air inlet after the argon gas blowing is completed. The adhesive part is used to bond the side walls of the elastic sealing sheet together to seal the air inlet.

[0021] Preferably, the inner diameter of the elastic sealing sheet gradually decreases away from the upper frame.

[0022] By adopting the above technical solution, the inner diameter of the elastic sealing sheet gradually decreases away from the upper frame, which is used for the elastic sealing sheet to closely adhere to the blowing pipe of the blowing device, facilitating the subsequent flanging of the elastic sealing sheet, and the adhesive part bonds and seals the elastic sealing sheet.

[0023] On the other hand, the present application provides an assembly method for a double-layer glass window, adopting the following technical solution: Assembling the double-layer glass window: Place the lower frame on a horizontal tabletop. First, install one side frame at one end of the lower frame, then install the first glass and the second glass on the lower frame and the side frame on one side, then install the side frame on the other side at the other end of the lower frame, and finally install the upper frame;

[0024] Filling argon gas: Insert the blowing pipe of the argon gas blowing device into the air inlet of the upper frame. When the blowing pipe is inserted into the air inlet, the elastic sealing sheet is sleeved on the blowing pipe. After the argon gas blowing is completed, the blowing pipe is pulled out, driving the elastic sealing sheet to flip out of the air inlet. The adhesive part bonds the elastic sealing sheet together, and then a sealing tape is attached to the upper frame to position the elastic sealing sheet;

[0025] Installing the double-layer glass window: After the double-layer glass window is filled with gas, drill holes in the window opening and embed expansion bolts. Place the window frame on the window opening and fix the window frame with expansion screws. Fill the gap between the window frame and the wall with foaming glue. After the window frame is installed, install the installation frame on the window frame.

[0026] By adopting the above technical solution, after the present application fills argon gas, the elastic sealing sheet seals the outer periphery of the blowing pipe, effectively improving the blowing efficiency of the blowing pipe and reducing the risk of air leakage. Since the aperture of the elastic sealing sheet gradually decreases, the bottom end of the elastic sealing sheet will closely adhere to the blowing pipe. When the blowing pipe is pulled out, it will drive the elastic sealing sheet to flange. While the elastic sealing sheet is flanging, the adhesive part will bond the side walls of the elastic sealing sheet together. After the blowing pipe is pulled out, the elastic sealing sheet will seal the air inlet at the same time, reducing the possibility of argon gas leakage.

[0027] In summary, when installing the first glass and the second glass, the installation frame effectively improves the connection tightness between the first glass and the second glass and the installation frame. The sealing component improves the sealing effect of the space formed by the first glass, the second glass and the installation frame, reducing the possibility of argon gas leaking from the corners where the first glass or the second glass contacts the installation frame.

Detailed Description of the Embodiments

[0032] The following further elaborates on the present application in conjunction with the attached Figures 1-3 drawings for a more detailed description.

[0033] An embodiment of the present application discloses a double - layer glass window structure. Referring to Figure 1 and Figure 2 , it includes a window frame 1 installed on a window opening, an installation frame 2 installed on the window frame 1, a glass one 3 and a glass two 4 installed in the installation frame 2. A space for filling argon is formed among the glass one 3, the glass two 4, and the installation frame 2. To improve the connection stability and sealing effect between the glass one 3 and the glass two 4 and the installation frame 2, a positioning block one 5 is fixed on the side wall of the glass one 3 in contact with the installation frame 2. The positioning block one 5 surrounds along the shape of the installation frame 2 to improve the stability of the glass one 3 on the installation frame 2. A positioning block two 6 is fixed on the side wall of the glass two 4 in contact with the installation frame 2, and the shape of the positioning block two 6 is the same as that of the positioning block one 5.

[0034] Referring to Figure 1 and Figure 2 ​, the mounting frame 2 includes an upper frame 21 located above the first glass 3 and the second glass 4, a lower frame 22 located below the first glass 3 and the second glass 4, and side frames 23 for positioning both sides of the first glass 3 and the second glass 4. The structures of the upper frame 21 and the lower frame 22 are the same, which is convenient for assemblers to assemble. The upper frame 21 and the lower frame 22 are both provided with a first positioning groove 19 for the first positioning block 5 and the second positioning block 6 to be inserted along the length direction. The side frame 23 is provided with a second positioning groove 20 for the first positioning block 5 and the second positioning block 6 to be inserted along the length direction. The first positioning groove 19 and the second positioning groove 20 are spliced to form a groove body with the same shape as the first positioning block 5 or the second positioning block 6, improving the stability of the first positioning block 5 and the second positioning block 6 in the mounting frame 2. The side frames 23 are located at both ends of the upper frame 21 and the lower frame 22, and the side frames 23 are also used to connect the upper frame 21 and the lower frame 22.

[0035] Refer to Figure 2 and Figure 3 , the side frame 23 is provided with a first embedding groove 8 for positioning the first glass 3 and the second glass 4 along the length direction. The bottom surface of the upper frame 21 is provided with a second embedding groove 14 along the length direction. The second embedding groove 14 is used for the first glass 3 and the second glass 4 to be installed on the upper frame 21 and the lower frame 22. Both ends of the side frame 23 are provided with a first insertion groove 15 for the upper frame 21 or the lower frame 22 to be inserted into. Both ends of the upper frame 21 are fixedly installed with a first insertion block 16 located in the first insertion groove 15. One end of the first insertion block 16 is located on the side of the first glass 3 away from the second glass 4, and the other end of the first insertion block 16 is located on the side of the second glass 4 away from the first glass 3. The first insertion block 16 is in a [ shape, which is used to block the connection gap between the first glass 3 and the second glass 4. In order to improve the connection stability between the upper frame 21 or the lower frame 22 and the side frame 23, a fixing plate 17 located between the first glass 3 and the second glass 4 is fixedly installed on the bottom surface of the upper frame 21. Two groups of fixing plates 17 are provided in the embodiment of the present application. Both ends of the side frame 23 are provided with a second fixing groove 18 for positioning the fixing plate 17. When the first insertion block 16 is inserted into the first insertion groove 15, the fixing plate 17 is simultaneously inserted into the second fixing groove 18, facilitating the upper frame 21 or the lower frame 22 to be closely attached to the first glass 3 and the second glass 4.

[0036] Refer to Figure 2 and Figure 3, a sealing assembly 7 is installed on the side frame 23, and the sealing assembly 7 is used to seal the gap where the first glass 3 or the second glass 4 contacts the side frame 23. The sealing assembly 7 includes a positioning plate 71, a sealing strip 72 fixedly installed on one side in the length direction of the positioning plate 71, and a sealing block 73 installed on the other side in the length direction of the positioning plate 71. Eight groups of the sealing assemblies 7 are provided in this application, with two groups provided at each end of the first glass 3 and two groups provided at each end of the second glass 4. The sealing strip 72 extends along the length direction of the first glass 3 or the second glass 4. An installation groove 9 is formed in the side frame 23 along the length direction. The installation groove 9 communicates with the embedding groove 8 and is used to position the sealing strip 72. The sealing strip 72 is made of an elastic material and the thickness of the sealing strip 72 is thicker than the thickness of the installation groove 9. The width of the positioning plate 71 is wider than the width of the sealing strip 72. An installation groove 10 is formed in the side frame 23 along the length direction, and the installation groove 10 is used to install the positioning plate 71. Fixing blocks 11 located on both sides in the length direction of the sealing strip 72 are fixedly arranged on one side of the positioning plate 71 close to the sealing strip 72. Fixing grooves 12 adapted to the fixing blocks 11 are formed in the side frame 23. When the positioning plate 71 is inserted into the installation groove 10, the gasket closely adheres to the first glass 3 or the second glass 4.

[0037] Referring to Figure 2 and Figure 3 , since the thickness of the sealing strip 72 is thicker than the thickness of the installation groove 9, when inserting, a frictional force will be generated between the sealing strip 72 and the first glass 3 or the second glass 4, which is inconvenient for the positioning plate 71 to be inserted and installed. The cross-section of the sealing block 73 in this application is convex. The side with a narrower width of the sealing block 73 is in close contact with the positioning plate 71 and has the same width as the positioning plate 71. An installation groove 13 adapted to the sealing block 73 is formed in the side frame 23. During installation, first install the positioning plate 71 in the side frame 23. The positioning plate 71 and the sealing strip 72 can be directly located in the installation groove 13. The installation groove 13 provides extra space. After the positioning plate 71 and the sealing strip 72 are installed, adjust the position of the positioning plate 71, and push the positioning plate 71 towards the position of the first glass 3 or the second glass 4. The sealing block 73 is inserted into the installation groove 13. When the sealing block 73 is inserted, it will gradually press against the positioning plate 71, and the fixing block 11 is inserted into the fixing groove 12. At the same time, the sealing strip 72 closely adheres to the first glass 3 or the second glass 4, and seals the gap between the first glass 3 or the second glass 4 and the side frame 23.

[0038] Referring to Figure 2 and Figure 3, for facilitating subsequent argon blowing, air inlet holes 24 are provided on both the upper frame 21 and the lower frame 22. The air inlet holes 24 are located between the first glass 3 and the second glass 4 and communicate with the space formed by the first glass 3 and the second glass 4. An elastic sealing sheet 25 is fixed along the inner wall of the air inlet hole 24, and the elastic sealing sheet 25 is in a circular ring shape. The inner diameter of the elastic sealing sheet 25 gradually shrinks away from the upper frame 21, which is convenient for improving the stability during blowing. An adhesive member is fixed on the outer side wall of the elastic sealing sheet 25, and the adhesive member can be double-sided tape or glue liquid, etc.

[0039] The implementation principle of the double-layer glass window structure in the embodiment of the present application is as follows: First, install a side frame 23 at one end of the lower frame 22, insert the first plug-in block 16 into the first plug-in groove 15, and synchronously insert the fixing plate 17 into the second fixing groove 18. After the lower frame 22 and one side frame 23 are installed, place the first glass 3 and the second glass 4 into the second embedding groove 14 of the lower frame 22 respectively, and then push the glass in the height direction with one side facing the first embedding groove 8 of the side frame 23. After the first glass 3 and the second glass 4 are installed, start installing the sealing component 7. First, place the positioning plate 71 and the sealing strip 72 into the first installation groove 9. Since the sealing strip 72 is relatively thick, it can be directly placed into the third installation groove 13. Then, first push the positioning plate 71 at the end close to the first glass 3 or the second glass 4, press one end of the fixing block 11 into the first fixing groove 12, and then insert the sealing block 73 into the third installation groove 13. When the sealing block 73 is inserted, it will drive the fixing block 11 to gradually enter the first fixing groove 12, and at the same time, the positioning plate 71 also enters the second installation groove 10, and the sealing strip 72 starts to squeeze the first glass 3 or the second glass 4 to seal the gaps between the first glass 3 or the second glass 4 and the side frame 23. Then, perform the same operation to install the side frame 23 on the other side, and finally install the upper frame 21 on the side frame 23.

[0040] The embodiment of the present application also provides an assembly method for a double-layer glass window, including assembling the double-layer glass window: Place the lower frame 22 on a horizontal table. First, install one side frame 23 at one end of the lower frame 22, then apply glass glue in the second embedding groove 14, and then install the first glass 3 and the second glass 4 on the lower frame 22 and one side frame 23. The glass glue improves the stability of the first glass 3 and the second glass 4 on the lower frame 22 on the one hand, and can also fill the gaps between the first glass 3 or the second glass 4 and the lower frame 22; After installing the first glass 3 and the second glass 4, install the side frame 23 on the other end of the lower frame 22. At this time, install the sealing component 7 in the side frame 23. After installing the sealing component 7, install the upper frame 21. At this time, apply glass glue on the first glass 3 and the second glass 4 to avoid the glass glue being applied on the upper frame 21, resulting in the dripping of the glue liquid during the installation of the upper frame 21 and affecting the aesthetics of the first glass 3 and the second glass 4;

[0041] Filling with argon: Insert the blowpipe of the argon blowing device into the air inlet hole 24 of the upper frame 21. When the blowpipe is inserted into the air inlet hole 24, the elastic sealing piece 25 is sleeved on the blowpipe. After the argon blowing is completed, the blowpipe is pulled out, driving the elastic sealing piece 25 to flip out of the air inlet hole 24, and the adhesive parts bond the elastic sealing pieces 25 together. Then, a sealing tape is attached to the upper frame 21 to position the elastic sealing piece 25; the elastic sealing piece 25 on the lower frame 22 can be flipped during installation. After the argon is blown, the protective layer of the double-sided tape is torn off, and the elastic sealing piece 25 is bonded to seal the air inlet hole 24 of the lower frame 22.

[0042] Installing double-glazed windows: After the double-glazed windows are filled with gas, drill holes in the window opening and embed expansion bolts. Place the window frame 1 on the window opening and fix the window frame 1 with expansion screws. Fill the gap between the window frame 1 and the wall with foaming glue. After the window frame 1 is installed, install the installation frame 2 on the window frame 1.

[0043] This application effectively improves the sealing effect of the double-sealed window and reduces the possibility of argon leakage inside the double glass caused by the falling off of the rubber strips of the double-sealed window.

[0044] The above are all preferred embodiments of this application. The protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
