Description

Technical Field

[0001] This utility model relates to the field of door and window technology, and in particular to a screen fixing structure and a screen window including the screen fixing structure. Background Technology

[0002] Currently, some doors and windows are equipped with screens. These screens effectively block mosquitoes from entering the room, providing good mosquito prevention while maintaining ventilation. Typically, a screen consists of a screen frame and a mesh screen fixed to the frame. The mesh screen, also known as an insect screen, can be made of materials such as fiberglass, polyester fiber, or stainless steel. Fiberglass mesh has good light transmission and corrosion resistance, and is lightweight, high-strength, and wear-resistant. Polyester fiber mesh is lightweight and easy to install and clean. Stainless steel mesh has good tensile strength and corrosion resistance, and a long service life.

[0003] In existing technologies, such as Figure 1 As shown, the main method of fixing the screen 10 in the screen window frame 20 is by using a pressing strip 30. Specifically, the screen window frame 20 has an installation groove 21, and the screen window frame 20 has a slot 22 on the side of the installation groove 21. During installation, the outer edge of the screen 10 is inserted into the installation groove 21 through the slot 22, and then the pressing strip 30 is pressed into the installation groove 21 through the slot 22. The pressing strip 30 and the screen window frame 20 are tightly fitted and fixed, thereby fixing the screen 10 between the pressing strip 30 and the groove wall of the installation groove 21, thus achieving the fixed installation of the screen 10. However, this screen fixing structure has the following defects.

[0004] 1. The outer edge of the mesh 10 is the cut edge 11 (i.e., the cut surface) formed after it has been cut. After the mesh 10 is fixed in the mounting groove 21 using the mesh pressing strip 30, the cut edge 11 of the mesh 10 protrudes at the groove opening 22 on the side of the mounting groove 21. Figure 1 As shown. When the mesh 10 is a stainless steel mesh, a burr structure is formed at the outer edge 11 of the mesh cut. Since the burr structure is exposed at the groove 22 of the screen frame 20, it may cause injury to people and reduce the appearance quality of the screen.

[0005] 2. The existing technology uses a single-layer rubber strip pressing structure, which has insufficient pressing strength. After long-term use, the pressing rubber strip 30 will age and deform, causing gaps between it and the groove wall of the mounting groove 21, further reducing the pressing strength. This poses a risk that the screen 10 may easily detach. Figure 2 As shown. Alternatively, during the use of mesh 10, if improper use or misoperation by personnel occurs, such as... Figure 3As shown, when a person's hand presses against one side of the mesh 10 and applies a force to the mesh 10 to make it detach from the mounting groove 21, there is a risk that the mesh 10 may easily detach due to the weak pressing strength. Utility Model Content

[0006] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a mesh fixing structure that effectively increases the mesh pressing strength.

[0007] To achieve the above objectives, this utility model provides a screen fixing structure, including a screen, a screen frame, and a screen sealing strip. The screen includes a main body distributed on the inner periphery of the screen frame and an outer edge fixed to the screen frame. The screen frame has a multi-layered mounting groove and an opening on the side of the mounting groove. The mounting groove includes at least two grooves connected sequentially along its depth direction. Each groove is fitted with a screen sealing strip that is tightly fitted and fixed to the screen frame. The outer edge of the screen is pressed into the mounting groove through the opening and is pressed between the groove wall of each groove and each screen sealing strip.

[0008] In the screen fixing structure involved in this application, the mounting groove is a multi-layered groove structure. Each layer of the groove is embedded with a pressing strip for pressing and fixing the outer edge of the screen. This makes the screen fixing structure a multi-layered groove and multi-layered pressing strip structure, which effectively improves the pressing strength and reliably prevents the outer edge of the screen from coming out of the mounting groove due to aging or deformation of the pressing strip or human error. This ensures the reliability of the screen being fixed in the screen window frame, making the screen window durable.

[0009] Furthermore, the preferred configuration of the mounting groove and slot on the screen window frame is as follows: the depth direction of the mounting groove is in the indoor / outdoor direction, then at least two grooves constituting the mounting groove are arranged side by side in the indoor / outdoor direction; the slot is located on the outdoor or indoor side of the mounting groove along the depth direction of the mounting groove. In this way, the operations of pressing the outer edge of the mesh into the mounting groove through the slot, pressing the mesh pressing strip into each groove through the slot, and cutting off the protruding portion of the outer edge of the mesh from the mounting groove through the slot are all performed on the side of the screen window frame where the slot is located, avoiding interference from the main body of the mesh with the above operations, making the fixing of the mesh easy.

[0010] Furthermore, along the direction from the bottom of the mounting groove towards the opening of the groove, the width of at least two of the grooves increases in a stepped manner in the horizontal direction perpendicular to the depth of the mounting groove. This better ensures that each layer of mesh pressing strip can be pressed firmly into the groove of that layer, and more reliably presses and fixes the outer edge of the mesh into the mounting groove of the screen window frame.

[0011] Furthermore, the two ends of the groove are a first end away from the main body of the mesh and a second end close to the main body of the mesh, respectively. The screen window sash frame has a groove protrusion extending toward the second end at the first end of the groove. The inner surface of the groove protrusion facing the bottom of the mounting groove is a cutting guide slope. The cutting guide slope extends obliquely in a manner that the further away from the second end, the closer to the bottom of the mounting groove. The screen window sash frame forms a guide corner at the end of the cutting guide slope away from the second end.

[0012] By using the groove protrusion and its cutting guide slope, when cutting off the outer edge of the screen from the protruding portion in the mounting groove, the cutting tool extends along the cutting guide slope to the guide corner to cut off the excess portion of the outer edge of the screen. This results in the outer edge of the screen, away from the main body of the screen, being the cut outer edge of the screen formed at the guide corner. This makes cutting the excess portion of the outer edge of the screen smoother and easier, and also ensures that the cut outer edge of the screen is concealed within the mounting groove by the groove protrusion, thus preventing the outer edge of the screen from being exposed at the groove. This prevents injury from burrs on the outer edge of the screen and improves the appearance quality of the screen. In addition, the protrusion of the groove reduces the distance between the two ends of the groove, which reduces the probability that the pressing strip embedded in the groove body next to the groove will come out of the groove due to aging and deformation. This ensures that the pressing strip next to the groove can be reliably kept in the groove body next to the groove, thus improving the reliability of the pressing.

[0013] Furthermore, the pressing strip embedded in the groove body adjacent to the groove opening abuts against the groove opening protrusion, and the abutting part of the two is further away from the bottom of the mounting groove relative to the outer edge of the mesh cut, which further increases the pressing reliability and can better accommodate the outer edge of the mesh cut in the mounting groove.

[0014] Preferably, the mounting groove has a double-layer structure, consisting of two grooves: a first groove located near the bottom of the mounting groove and a second groove located near the opening. That is, the preferred mesh fixing structure is a double-layer groove and double-layer mesh pressing strip structure, which simplifies the structure of the screen window frame while improving the mesh pressing strength.

[0015] Furthermore, the screen window frame is provided with abutting protrusions on the groove wall of each groove, and the abutting protrusions, the outer edge of the mesh, and the mesh pressing strip are pressed tightly together in sequence to better improve the reliability of the mesh pressing.

[0016] Preferably, the mesh is a metal mesh or a fiberglass mesh. When the mesh is a metal mesh, stainless steel mesh is preferred, as it is durable and extends the lifespan of the screen. When the mesh is a fiberglass mesh, it has good light transmission and corrosion resistance, and is lightweight, high-strength, wear-resistant, durable, and also extends the lifespan of the screen.

[0017] This utility model also provides a screen window, including a fixed screen window frame and a screen window sash. The screen window sash includes a screen mesh, a screen window sash frame, and a mesh pressing strip. The screen mesh, the screen window sash frame, and the mesh pressing strip are connected by the screen mesh fixing structure described above. The screen window sash frame is installed on the screen window fixed frame.

[0018] Furthermore, along the horizontal width direction of the screen sash, one side of the screen sash frame is rotatably mounted to the screen fixing frame, and the other side of the screen sash frame is detachably mounted to the screen fixing frame. The screen sash opens by rotating relative to the screen fixing frame towards the interior. Therefore, the screen of this application is an inward-opening screen, which facilitates the cleaning of the screen mesh.

[0019] As described above, the screen fixing structure and screen window involved in this utility model have the following beneficial effects:

[0020] This application is based on a multi-layer groove structure for the installation groove. Each layer of the groove is embedded with a pressing strip for pressing and fixing the outer edge of the screen. This makes the screen fixing structure a multi-layer groove and multi-layer pressing strip structure, which effectively improves the pressing strength and reliably prevents the outer edge of the screen from coming out of the installation groove due to aging or deformation of the pressing strip or human error. This ensures the reliability of the screen being fixed in the window sash frame, making the screen durable. Attached Figure Description

[0066] This application relates to the field of door and window technology, and in particular to a screen window, a screen mesh fixing structure for the screen window, and a screen mesh fixing method for connecting the screen mesh fixing structure.

[0067] For ease of description, in the following embodiments, the directions are defined as follows: the thickness direction of the screen is defined as the front-to-back direction, the width direction of the screen in the horizontal direction is defined as the left-to-right direction, and the height direction of the screen in the vertical direction is defined as the up-down direction. Simultaneously, the front-to-back direction is also the indoor / outdoor direction, the left-to-right direction is the horizontal direction, and the up-down direction is the vertical direction. Based on this, Figure 4 ,as well as Figures 6 to 8 In the view shown, the view angle is taken as a person standing on the outside side of the screen window looking towards the inside. The top of the paper is the front direction (i.e., the direction of the inside), the bottom of the paper is the back direction (i.e., the direction of the outside), the left and right sides of the paper are the left and right directions respectively, and the front and back of the paper are the top and bottom directions respectively.

[0068] like Figures 4 to 6 As shown, the screen window of this utility model includes a fixed screen window frame 40 and a screen window sash 70. The screen window sash 70 includes a screen mesh 10, a screen window sash frame 20, and a mesh pressing strip 30. The screen mesh 10, the screen window sash frame 20, and the mesh pressing strip 30 are connected by a screen mesh fixing structure. The screen window sash frame 20 is installed on the screen window frame 40, thereby installing the entire screen window sash 70 on the screen window frame 40. The screen mesh 10 serves the functions of insect prevention and ventilation, and the screen mesh 10 also serves as an insect-proof net. Typically, the screen window frame 40 includes a pair of horizontal frame profiles 41 that are distributed vertically and extend horizontally, and a pair of vertical frame profiles 42 that are distributed horizontally and extend vertically. The horizontal frame profiles 41 and the vertical frame profiles 42 are preferably both made of aluminum alloy. The screen frame 20 of the screen sash 70 includes a pair of horizontal sash profiles 28 that are distributed vertically and extend horizontally, and a pair of vertical sash profiles 29 that are distributed horizontally and extend vertically. The horizontal sash profiles 28 and the vertical sash profiles 29 are preferably made of aluminum alloy.

[0069] like Figure 6 and Figure 7As shown, the screen fixing structure of this utility model includes a screen 10, a screen window frame 20, and a screen sealing strip 30. The screen 10 includes a main body 12 and an outer edge 13 surrounding the main body 12. The main body 12 is a vertical planar structure and is distributed on the inner periphery of the screen window frame 20. The outer edge 13 is fixed to the screen window frame 20 by the screen sealing strip 30. Specifically: the outer edge 13 of the mesh on the left side of the main body 12 is fixed to the longitudinal sash profile 29 on the left side of the screen frame 20 via a mesh-pressing adhesive strip 30; the outer edge 13 of the mesh on the right side of the main body 12 is fixed to the longitudinal sash profile 29 on the right side of the screen frame 20 via a mesh-pressing adhesive strip 30; the outer edge 13 of the mesh on the upper side of the main body 12 is fixed to the transverse sash profile 28 on the upper side of the screen frame 20 via a mesh-pressing adhesive strip 30; and the outer edge 13 of the mesh on the lower side of the main body 12 is fixed to the transverse sash profile 28 on the lower side of the screen frame 20 via a mesh-pressing adhesive strip 30. The structure of the outer edge 13 of the mesh on each side of the screen 10 being fixed to each sash profile of the screen frame 20 via mesh-pressing adhesive strips 30 is the same. The preferred embodiment of the screen fixing structure is illustrated below, taking the outer edge 13 of the screen 10 on the left side of the screen as an example, which is fixed to the longitudinal sash profile 29 on the left side of the screen frame 20 by the screen pressing adhesive strip 30.

[0070] like Figure 7 and Figure 8 As shown, the screen window frame 20 has a mounting groove 21 and a slot 22 on the side of the mounting groove 21. In particular, the mounting groove 21 has a multi-layer structure, that is, the mounting groove 21 includes at least two grooves 23 connected in sequence along its depth direction, and the bottom surface of the mounting groove 21 in its depth direction is its groove bottom; each groove 23 is embedded with a mesh pressing strip 30 that is tightly fitted and fixed to the screen window frame 20; the outer edge 13 of the screen 10 is pressed into the mounting groove 21 through the slot 22 and is pressed between the groove wall of each groove 23 and each mesh pressing strip 30.

[0071] Furthermore, the number of grooves 23 constituting the mounting groove 21 is determined according to actual needs, and can be two, three, or more. The mounting groove 21 is correspondingly a double-layered, triple-layered, or multi-layered structure. In this embodiment, to simplify the structure of the screen window frame 20, the mounting groove 21 is set as a double-layered structure, comprising two grooves 23. The two grooves 23 are a first groove 231 located near the bottom of the mounting groove 21, and a second groove 232 located near the opening 22. The mesh pressing strip 30 embedded in the first groove 231 is defined as the first mesh pressing strip 31, and the mesh pressing strip 30 embedded in the second groove 232 is defined as the second mesh pressing strip 32. The outer edge 13 of the screen 10 is pressed between the groove wall of the first groove 231 and the first mesh pressing strip 31, and between the groove wall of the second groove 232 and the second mesh pressing strip 32.

[0072] This utility model also relates to a method for fixing the above-mentioned mesh fixing structure, which includes the following steps:

[0073] S1, such as Figure 10a As shown, the outer edge 13 of the screen 10 is pressed into the mounting groove 21 of the screen window frame 20 through the groove 22, and the outer edge 13 covers the entire groove wall of the mounting groove 21. Then, the left side of the outer edge 13 away from the main body 12 will inevitably protrude from the mounting groove 21.

[0074] S2, such as Figure 10b As shown, along the direction away from the bottom of the mounting groove 21, the mesh pressing strips 30 are successively embedded in the remaining grooves 23 except for the one immediately adjacent to the groove opening 22. That is, the first mesh pressing strip 31 is first embedded in the first groove 231, and the first mesh pressing strip 31 clamps and fixes the outer edge of the mesh 13 in the first groove 231, thereby achieving the initial pressing and fixing of the outer edge of the mesh 13. In other embodiments, when there are two or more grooves 23, the mesh pressing strips 30 are pressed in, but the groove 23 closest to the groove opening 22 is left empty.

[0075] S3, such as Figure 10c As shown, the portion of the outer edge 13 of the net that protrudes from the mounting groove 21 on the side away from the net body 12 is cut off, so that the outer edge 13 of the net has a net cutting edge 11, which is the outer edge formed after the outer edge 13 of the net is cut off.

[0076] S4, such as Figure 10d As shown, a mesh pressing strip 30 is embedded in the groove 23 adjacent to the groove opening 22, that is, a second mesh pressing strip 32 is embedded in the second groove 232. The second mesh pressing strip 32 clamps and fixes the outer edge of the mesh 13 in the second groove 232, thereby achieving further compaction and fixation of the outer edge of the mesh 13.

[0077] In steps S1, S2, and S4 of the above-mentioned mesh fixing method, as follows: Figure 10a , Figure 10b and 10d As shown, the operation of pressing the outer edge 13 of the mesh into the mounting groove 21 and pressing the mesh pressing strip 30 into each groove 23 can be performed with the aid of the removal tool 50; in the above step S3, as Figure 10c As shown, the operation of cutting off the portion of the outer edge 13 of the mesh that protrudes from the mounting groove 21 can be performed using a cutting tool 60.

[0078] In this application, the mounting groove 21 has a multi-layer groove structure 23, and each layer of the groove 23 is embedded with a pressing strip 30 for pressing and fixing the outer edge 13 of the screen 10. Each pressing strip 30 is tightly fitted and fixed to the groove wall of the layer of the groove 23, thereby fixing the pressing strip 30 and the outer edge 13 of the screen in the groove 23. This makes the screen fixing structure a multi-layer pressing structure of multi-layer groove 23 and multi-layer pressing strip 30, preferably a double-layer groove 23 and double-layer pressing strip 30 pressing structure. Compared with the single-layer pressing structure of the prior art, this application effectively improves the pressing strength and reliably avoids the outer edge 13 of the screen from coming out of the mounting groove 21 due to aging and deformation of the pressing strip 30 or due to human error. This ensures the reliability of the screen 10 being fixed in the screen window frame 20, making the screen window durable.

[0079] Preferably, the mesh pressing strip 30 in each groove 23 is a long strip extending along the length of the screen frame 20, which makes the tight fit between the mesh pressing strip 30 and the screen frame 20 more reliable, effectively preventing the mesh pressing strip 30 from coming out of the groove 23, and more reliably ensuring the force applied by the mesh pressing strip 30 to the screen 10, ensuring the reliability of the mesh pressing, and thus more reliably preventing the screen 10 from coming out of the mounting groove 21.

[0080] Furthermore, such as Figure 7 and Figure 8 As shown, the depth direction of the mounting groove 21 is the indoor / outdoor direction, and the multiple grooves 23 constituting the mounting groove 21 are arranged side by side along the indoor / outdoor direction; the groove opening 22 is located on the outdoor or indoor side of the mounting groove 21 along the depth direction of the mounting groove 21. Thus, the operations of pressing the outer edge of the mesh 13 into the mounting groove 21 through the groove opening 22, pressing the mesh pressing strip 30 into each groove 23 through the groove opening 22, and cutting off the protruding part of the outer edge of the mesh 13 from the mounting groove 21 through the groove opening 22 are all performed on the side of the screen window frame 20 where the groove opening 22 is located, that is, on the front or rear side of the screen window frame 20, to avoid the mesh body 12 on the right side of the screen window frame 20 interfering with the above operations, making it easy to fix the screen 10. In this embodiment, the slot 22 is located on the outdoor side of the mounting slot 21, so that the connection structure between the mesh sealing strip 30, the screen 10, and the screen frame 20 is only exposed on the outdoor side of the screen. Users cannot see this connection structure from the indoor side, thus improving the aesthetics of the screen from the indoor side. Simultaneously, the second slot 232 is closer to the outdoor side than the first slot 231. Furthermore, in the front-rear direction, the first slot 231 is located closer to the center of the screen, while the second slot 232 is located closer to the outdoor side of the screen.

[0081] like Figure 7 and Figure 8As shown, the width direction of the groove 23 is a horizontal direction perpendicular to the depth direction of the mounting groove 21, i.e., a left-right direction. The width of the multiple grooves 23 is a segmented widening structure. Specifically, along the direction from the bottom of the mounting groove 21 towards the opening 22, the width of the multiple grooves 23 increases in a stepped manner from front to back. That is, the groove 23 closest to the bottom of the mounting groove 21 has the smallest width, and the groove 23 closest to the opening 22 has the largest width. Therefore, the width of the second groove 232 is greater than the width of the first groove 231. Thus, a dividing embankment 27 is formed on the groove wall of the mounting groove 21 at the connection between the first groove 231 and the second groove 232. The dividing embankment 27 is also distributed at the bottom of the second groove 232. The second mesh pressing strip 32 embedded in the second groove 232 can abut against the dividing embankment 27 at the bottom of the second groove 232, further pressing the outer edge 13 of the mesh firmly into the second groove 232. Thus, this application can better ensure that each layer of mesh pressing strip 30 is firmly pressed into the groove 23 of that layer, and more reliably press and fix the outer edge 13 of the screen 10 into the mounting groove 21 of the screen window frame 20. In addition, the depth of the first groove 231 should be deep enough to accommodate at least the entire first mesh pressing strip 31. In this way, even if part of the outer edge 13 of the screen 10 detaches from the second mesh pressing strip 32 during subsequent use, the first mesh pressing strip 31 can still reliably press the outer edge 13 of the screen 10 into the first groove 231, preventing the screen 10 from coming out of the mounting groove 21 and improving the reliability of mesh pressing.

[0082] Preferably, such as Figure 7 and Figure 8 As shown, the left and right walls of each trough 23 extend straight back and forth along the indoor / outdoor direction. The right walls of multiple troughs 23 near the main body 12 are aligned in the left-right direction, while the left walls of multiple troughs 23 away from the main body 12 are staggered in the left-right direction, thus forming a dividing embankment 27 at the junction of two adjacent troughs 23. Therefore, the right walls of the first trough 231 and the second trough 232 are aligned left-right, but the left wall of the first trough 231 is located to the right of the left wall of the second trough 232. Of course, in other embodiments, the left and right walls of each trough 23 can also be staggered left-right to form the dividing embankment 27; for example, the right wall of the first trough 231 is located to the left of the right wall of the second trough 232, and the left wall of the first trough 231 is located to the right of the left wall of the second trough 232.

[0083] like Figure 7 and Figure 8As shown, the screen frame 20 has an abutting protrusion 26 on the groove wall of each groove 23. The abutting protrusion 26 on the groove wall of each groove 23 abuts against the pressing mesh rubber strip 30 in the groove 23. That is, the abutting protrusion 26, the outer edge of the mesh 13 and the pressing mesh rubber strip 30 are pressed tightly in sequence, further pressing the outer edge of the mesh 13 into the groove 23, thereby improving the reliability of pressing the mesh.

[0084] Furthermore, such as Figure 7 and Figure 8 The left and right ends of the slot 22 are respectively the first end 221 away from the main body of the net 12 and the second end 222 close to the main body of the net 12. The first end 221 is the left end of the slot 22, and the second end 222 is the right end of the slot 22. The screen window frame 20 has a slot protrusion 24 extending to the right towards the second end 222 at the first end 221 of the slot 22. The inner surface of the slot protrusion 24 facing the bottom of the mounting groove 21 is an inclined cutting guide slope 241. The inclination of the cutting guide slope 241 is such that the further away from the second end 222, the closer to the bottom of the mounting groove 21; that is, the left end of the cutting guide slope 241 extends inclined to the left front and extends to the left side of the groove wall of the second groove 232. Thus, the screen window frame 20 forms a guide angle 25 at the left end of the cutting guide slope 241, away from the second end 222. The guide angle 25 is the angle between the left side wall of the second groove 232 and the cutting guide slope 241, and the guide angle 25 is an obtuse angle. With this arrangement, as... Figure 10c , Figure 10d and Figure 11 As shown, in step S3 above, when using the cutting tool 60 to cut off the protruding portion of the outer edge 13 of the screen from the mounting groove 21, the cutting tool 60 extends along the cutting guide slope 241 to the guide corner 25 to cut off the excess portion of the outer edge 13 of the screen. That is, the excess portion of the outer edge 13 of the screen is cut off at the inner end of the cutting guide slope 241. The outer edge 11 of the screen formed after the outer edge 13 of the screen is cut is located at the guide corner 25. In this way, the cutting of the excess portion of the outer edge 13 of the screen is smoother and easier to operate. It also ensures that the outer edge 11 of the screen (i.e., the cut surface) formed after cutting is covered by the groove protrusion 24 on its indoor side. The outer edge 11 of the screen is hidden in the mounting groove 21, thereby preventing the outer edge 11 of the screen from being exposed from the groove 22. This not only prevents the burr structure of the outer edge 11 of the screen from causing injury to people, but also improves the appearance quality of the screen. In addition, the protrusion 24 in the slot reduces the distance between the left and right ends of the slot 22, which can reduce the probability that the second pressing strip 32 embedded in the second groove 232 adjacent to the slot 22 will come out of the slot 22 due to aging and deformation. This ensures that the second pressing strip 32 adjacent to the slot 22 can be reliably kept in the second groove 232 adjacent to the slot 22, thereby improving the reliability of pressing.

[0085] The concealed structure of the outer edge 11 of the mesh screen 10 allows this application to be well-suited for metal mesh screens 10, and also for conventional soft mesh screens 10. Therefore, the mesh screen 10 is preferably a metal mesh or a fiberglass mesh. When the mesh screen 10 is a metal mesh, stainless steel mesh is preferred, as it is durable and extends the service life of the screen. When the mesh screen 10 is a fiberglass mesh, it has good light transmission and corrosion resistance, and is lightweight, high-strength, wear-resistant, durable, and extends the service life of the screen.

[0086] like Figure 11 As shown, the second mesh pressing strip 32, embedded in the second groove 232 adjacent to the groove opening 22, abuts against the groove opening protrusion 24. The abutting portion of the second mesh pressing strip 32 and the groove opening protrusion 24 is further away from the bottom of the mounting groove 21 relative to the outer edge 11 of the mesh cut. In other words, the abutting portion of the second mesh pressing strip 32 and the groove opening protrusion 24 is closer to the outdoor side relative to the outer edge 11 of the mesh cut, further increasing the reliability of the mesh pressing and better containing the outer edge 11 of the mesh 10 within the mounting groove 21. Therefore, the function of the second mesh pressing strip 32 is to both cover the sharp burrs of the cut mesh 10 within the mounting groove 21 and further press the outer edge 13 of the mesh 10 firmly within the mounting groove 21.

[0087] Preferably, such as Figure 7 and Figure 8 As shown, the outer surface of the groove protrusion 24, facing away from the bottom of the mounting groove 21, is distributed on the extended surface of the outer surface of the screen window frame 20 on that side. That is, the outer surface of the groove protrusion 24 and the outdoor surface of the screen window frame 20 are in the same vertical plane, improving the flatness of the outdoor surface of the screen window frame 20, reducing uneven structures, and thus improving the appearance quality of the screen. Since the outer surface of the groove protrusion 24 is a vertical plane, and the inner surface of the groove protrusion 24 is an inclined cutting guide slope 241, an acute angle is formed between the cutting guide slope 241 of the groove protrusion 24 and its outdoor surface. Furthermore, the top right side of the groove protrusion 24 has a rounded arc surface, which transitions between the right end of the cutting guide slope 241 and the right end of the rear surface of the groove protrusion 24.

[0088] In summary, the installation steps for the mesh fixing structure with the above-mentioned structure are as follows.

[0089] First, such as Figure 10a As shown, on the rear side of the screen frame 20, the outer edge 13 of the screen 10 is pressed forward into the mounting groove 21 from the groove 22 using the removal tool 50. The outer edge 13 covers at least the entire groove wall of the mounting groove 21. The outer edge 13 covers the front bottom and left and right groove walls of the first groove 231, as well as the front bottom and left and right groove walls of the second groove 232. The outer edge 13 also covers the cutting guide slope 241 of the guide corner 25 and the groove protrusion 24.

[0090] Second, such as Figure 10b As shown, the first pressing strip 31 is pressed forward into the first groove 231 from the groove opening 22 using the removal tool 50. The first pressing strip 31 abuts against the front bottom, left side wall and right side wall of the first groove 231, pressing the outer edge 13 of the mesh tightly into the first groove 231.

[0091] Third, such as Figure 10c As shown, the cutting tool 60 is inserted from the slot 22 along the cutting guide slope 241 to the guide corner 25, where the outer edge 13 of the net is cut off, thereby cutting off the part of the outer edge 13 of the net that extends out of the mounting slot 21, and giving the outer edge 13 of the net a net cutting outer edge 11 distributed at the guide corner 25.

[0092] Fourth, such as Figure 10d As shown, the second pressing strip 32 is pressed forward into the second groove 232 from the groove opening 22 using the removal tool 50. The second pressing strip 32 abuts against the left and right groove walls of the second groove 232 and the dividing embankment 27, further pressing the outer edge of the net 13 into the second groove 232. At the same time, the abutting part of the second pressing strip 32 and the groove protrusion 24 covers the outer cutting edge 11 of the outer edge of the net 13, so that the outer cutting edge 11 of the net is hidden in the installation groove 21.

[0093] In summary, the mesh fixing structure with the above-described structure has the following advantages.

[0094] The existing single-layer adhesive strip pressing structure is upgraded to a double-layer adhesive strip pressing structure with a double-layer groove 23 and a double-layer pressing adhesive strip 30. Combined with the inclined groove protrusion 24 extending from the inner surface, a new composite double-layer adhesive strip pressing structure is formed. On the one hand, it increases the pressing strength, effectively reduces the probability of the mesh 10 coming out of the mounting groove 21, extends the product's service life, reduces maintenance costs, and reduces resource consumption, complying with energy conservation and environmental protection policies. On the other hand, it avoids exposing the cut surface of the mesh 10, increasing product safety and effectively reducing the risk of complaints. It is suitable for both metal mesh 10 and conventional soft mesh 10, meeting the needs of different consumers and expanding the product's application range. Ultimately, it enhances the product's competitiveness.

[0095] Furthermore, the screen window involved in this application is an inward-opening screen window. Specifically: such as... Figure 4 and Figure 5 As shown, along the horizontal width direction of the screen sash 70, the screen sash frame 20 on the left side of the screen sash 70 is rotatably mounted to the screen fixing frame 40 via a hinge, and at least the screen sash frame 20 on the right side of the screen sash 70 is detachably mounted to the screen fixing frame 40. Figure 4 and Figure 5In the illustrated embodiment, the left longitudinal sash 29 of the screen sash 70 is rotatably mounted to the left longitudinal frame 42 of the screen fixing frame 40 via a hinge. The right longitudinal sash 29, upper transverse sash 28, and lower transverse sash 28 of the screen sash 70 are respectively and detachably connected to the right longitudinal frame 42, upper transverse frame 41, and lower transverse frame 41 of the screen fixing frame 40 via magnetic attraction. Furthermore, a portion of the screen fixing frame 40 covers the outdoor side of the screen sash 70. When the screen is normally closed, the screen sash 70 is magnetically attached to the screen fixing frame 40. When the screen 10 needs to be cleaned, rotate the screen sash 70 forward toward the indoor side relative to the screen frame 40, thereby opening the screen sash 70. Since the screen sash 70 is opened toward the indoor side, the screen 10 is located on the indoor side after the screen sash 70 is opened, which facilitates the cleaning of the screen 10.

[0096] Furthermore, in the screen window involved in this application, the screen window fixing frame 40 can be fixedly installed in the following ways: the screen window fixing frame 40 is directly fixed to the building; or, the screen window fixing frame 40 is fixed to the door and window fixing frame 80 of the glass door and window. In a specific embodiment, such as Figure 9 As shown, the screen window fixing frame 40 is fixed to the outdoor side of the door and window fixing frame 80 of the glass door and window by several screws, thereby assembling the screen window as a whole on the outdoor side of the glass door and window.
