Description

Technical Field

[0001] This invention relates to the field of door and window installation technology, and in particular to a method for assembling a screen window. Background Technology

[0002] In related technologies, window screens include a mesh screen and a frame. The mesh screen needs to be pressed tightly against the frame with a strip, and the frame pulls the mesh screen taut, so that the mesh screen can block mosquitoes and other insects.

[0003] However, the pressing and assembly of the screen and frame requires the use of processing equipment. In other words, the assembly of the screen and frame needs to be completed in the factory, which means that the screen needs to be transported as a whole window, which greatly increases the transportation cost. Moreover, for large screens, it is even necessary to use hoisting to transport them into the house for installation, which is very inconvenient. Summary of the Invention

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art.

[0005] The present invention provides a method for assembling a screen window, comprising providing a screen mesh, an elastic frame and a window frame, wherein the elastic frame is arranged around the screen mesh, the inner periphery of the elastic frame is connected to the outer periphery of the screen mesh to drive the screen mesh to be tensioned, the window frame is provided with a window, the window is adapted to the elastic frame, the outer surface of the elastic frame is connected with a first mating part, and the inner surface of the window is provided with a second mating part. Apply pressure from the outside to the inside to the edge of the elastic frame, and place the deformed elastic frame into the window, so that the first mating part and the second mating part are opposite each other; The pressure on the elastic frame is released, and the elastic frame expands outward elastically to drive the first mating part and the second mating part to be detachably connected.

[0006] According to an embodiment of the present invention, a method for assembling a window screen has at least the following advantages: the inner periphery of the elastic frame is connected to the outer periphery of the screen, and the screen is kept taut due to the stretching action of the elastic frame, which helps to block mosquitoes and avoids excessive swaying of the screen due to wind. The inner surface of the window is adapted to the outer surface of the elastic frame, and the outer surface of the elastic frame is connected to a first mating part, while the inner surface of the window is provided with a second mating part. During assembly, the user can apply pressure from the outside to the inside to the frame of the elastic frame, causing the frame to bend and deform inward, making it easier for the elastic frame to fit with the window frame. The deformed elastic frame is then placed inside the window. After the elastic frame is in place, the first and second mating parts are positioned opposite each other. The user can then release the pressure applied to the elastic frame. Under the elastic action of the elastic frame... This method allows the elastic frame to expand outwards, enabling the first and second mating parts to be detachably connected. The screen assembly method utilizes the outward elastic expansion of the elastic frame, combined with the detachable connection of the first and second mating parts, to assemble the screen and window frame. Compared to the traditional method of assembling the screen and frame using pressure strips, this method is simpler and more convenient, reducing reliance on processing equipment. It allows for on-site assembly of the screen and window frame without the need for transporting the entire window, thus reducing transportation costs. Furthermore, the elasticity of the frame allows for folding during transport, reducing its volume and further lowering costs. During assembly, the elasticity of the frame allows the screen to quickly unfold and return to its taut state, making assembly simpler and more convenient.

[0007] According to some embodiments of the present invention, the first mating part is a locking strip, and the second mating part is a locking groove provided on the inner surface of the window frame. The locking groove is recessed outward, and the locking strip can be fitted into the locking groove.

[0008] The first mating part is a retaining strip, and the second mating part is a retaining groove located on the inner periphery of the window frame, with the groove recessed outwards. The elastic frame is pressed inwards and placed at the window, and after the first mating part and the second mating part are aligned, the compressive force on the elastic frame is released. Under the elastic expansion of the elastic frame, it is beneficial to drive the first mating part and the second mating part to be detachably connected, and improve the connection stability between the first mating part and the second mating part, that is, improve the connection stability between the elastic frame and the window frame, and make assembly simpler and more convenient.

[0009] According to some embodiments of the present invention, a rearwardly opening notch is provided at the corner of the window frame, and the notch communicates with the slot; inserting the deformed elastic frame into the window includes: Align the corners of the flexible frame with the notch and apply pressure toward the window frame. The corners of the flexible frame will then pass through the notch and be inserted into the window.

[0010] Considering that the first mating part hinders the insertion of the elastic frame into the window during assembly, requiring compression, this screen assembly method incorporates a rearward-opening notch at the corner of the window frame, connected to a slot. When inserting the deformed elastic frame into the window, the user aligns the corner of the elastic frame with the notch and applies pressure towards the window frame, allowing the corner to pass smoothly through the notch and into the window. This reduces the obstruction caused by the corner of the elastic frame, facilitating the engagement of the elastic frame and making screen assembly simpler and more convenient.

[0011] According to some embodiments of the present invention, the elastic frame is square in shape, and each of the four sides of the elastic frame is connected with a retaining strip, and the ends of the four sides protrude through the retaining strip.

[0012] Specifically, the flexible frame is square in shape, with locking strips connected to all four edges. The locking slots are recessed outwards. When the flexible frame is pressed inwards, it is placed inside the window, and the locking strips are aligned with the slots on the inner surface of the window frame. After the pressure on the flexible frame is released, the locking strips at all four edges expand outwards due to the frame's elastic recovery, allowing them to engage with the slots. This facilitates the assembly of the flexible frame with the window frame. The fact that all four edges of the flexible frame are connected via locking strips and slots improves the connection stability between the flexible frame and the window frame, reducing the risk of the flexible frame detaching from the window due to external wind forces.

[0013] According to some embodiments of the present invention, the inner surface of the window frame is provided with an inwardly open limiting groove, the limiting groove having a bottom wall and side walls arranged at angles, and the retaining strip having a first wall surface and a second wall surface arranged at angles; to drive the first mating part and the second mating part to be detachably connected, including: The card strip is fitted into the card slot, with the first wall surface abutting against the bottom wall and the second wall surface abutting against the side wall.

[0014] Considering the influence of windy, rainy, or extreme weather, outdoor air velocity is high, and screens tend to move outwards. With the end closer to the interior as the rear end and the end closer to the exterior as the front end, the screen assembly method features an inwardly opening limiting groove on the inner surface of the window frame. A locking groove is located at the bottom wall of the limiting groove. When the locking strip engages with the locking groove, the elastic expansion of the elastic frame allows the first wall surface to abut against the bottom wall, preventing the locking strip from dislodging inwards from the locking groove and thus limiting the movement of the elastic frame in the vertical plane. The second wall surface abuts against the side wall, preventing the locking strip from dislodging forward from the locking groove and thus limiting the movement of the elastic frame in the horizontal plane. This effectively improves the connection stability between the elastic frame and the window frame, reducing the risk of the elastic frame falling off.

[0015] According to some embodiments of the present invention, the limiting groove is arranged to open rearward; the method for assembling the screen window further includes: A cover plate and a baffle are provided, with the front end of the cover plate connected to the baffle. The cover plate is placed behind the limiting groove. The cover plate is detachably connected to the rear end of the window frame. The baffle is at least partially located inside the locking strip.

[0016] The limiting groove is open to the rear. After the elastic frame and window frame are assembled, the screen window assembly method allows the cover plate to be placed behind the limiting groove. The cover plate is detachably connected to the rear end of the window frame, meaning the cover plate is placed on the end of the window frame closest to the interior. The locking strip is hidden between the cover plate and the window frame, which helps maintain the flatness of the assembled screen window. The cover plate also helps restrict the elastic frame from detaching from the window and limits the displacement of the elastic frame and window frame in the horizontal plane, reducing the risk of the elastic frame falling off. The front end of the cover plate is connected to a baffle, which is at least partially located inside the locking strip. The baffle can abut against the inner surface of the locking strip, thereby restricting the locking strip from detaching from the groove and improving the connection stability between the elastic frame and the window frame.

[0017] According to some embodiments of the present invention, the card strip includes a connecting piece, a first surrounding piece, a second surrounding piece, and an insert piece. The first surrounding piece, the connecting piece, and the second surrounding piece are connected in sequence to form a groove. At least one of the first surrounding piece and the second surrounding piece is provided with a protruding edge protruding towards the groove. The groove is used to engage with an elastic frame, and the protruding edge is used to abut against the inner periphery of the elastic frame. The insert piece is provided at the end of the connecting piece away from the groove and is used to engage with the card groove.

[0018] The first gusset, the connecting piece, and the second gusset are connected in sequence to form a recess. At least one of the first and second gussets has a protruding edge that protrudes into the recess. The user can align the recess with the frame of the elastic frame and, by rotating and pressing the retaining strip relative to the elastic frame, make the recess engage with the frame of the elastic frame. The protruding edge abuts against the inner circumference of the elastic frame, thereby preventing the elastic frame from coming out of the recess and improving the connection stability between the elastic frame and the retaining strip. The insert is located at the end of the connecting piece away from the recess. After the elastic frame is deformed inward and inserted into the window, and the pressure on the elastic frame is released, the retaining strip expands outward under the elastic action of the elastic frame, and the insert of the retaining strip engages with the slot, thereby realizing the assembly of the elastic frame and the window frame.

[0019] According to some embodiments of the present invention, a first mating part is connected to the outer surface of the elastic frame, including: Align the opening of the slot with the edge of the elastic frame, and rotate the locking strip in the first direction to drive the edge portion of the elastic frame into the slot. Rotate the locking strip in the opposite direction of the first direction and apply pressure to the locking strip toward the elastic frame so that the edge of the elastic frame fits into the groove and the protruding edge abuts against the inner surface of the elastic frame.

[0020] When connecting the card strip and the elastic frame, the user can first align the opening of the slot of the card strip with the edge of the elastic frame, and then rotate the card strip in the first direction to bring the edge of the elastic frame closer to the slot, so that the edge of the elastic frame is placed into the slot, and the convex edge of the card strip is rotated to the inside of the elastic frame. Then, rotate the card strip in the opposite direction of the first direction and apply pressure to the card strip toward the elastic frame so that the convex edge of the card strip hooks onto the inner surface of the elastic frame, and the edge of the elastic frame is engaged with the slot, thereby preventing the elastic frame from coming out of the slot and improving the connection stability between the elastic frame and the card strip.

[0021] According to some embodiments of the present invention, the elastic frame includes a sleeve, an elastic strip, and a corner block. The sleeve has a through-hole, and the elastic strip corresponds one-to-one with the sleeve. The elastic frame is square-shaped. The inner periphery of the elastic frame is connected to the outer periphery of the mesh, including: Connect the top, left, bottom, and right edges of the mesh to the four strips respectively; The cavity through which the elastic strips pass is designed, and each of the two adjacent elastic strips is connected to a corner block.

[0022] The top, left, bottom, and right edges of the mesh are all connected with sleeves, and each sleeve has a through-hole. The elastic strips correspond one-to-one with the sleeves. When assembling the elastic frame, the user can pass the elastic strips through the cavities and connect two adjacent elastic strips to a corner block, so that multiple elastic strips form a square frame. Under the elastic action of the elastic strips, the mesh is driven to be in a taut state, and the first mating part can be detachably connected to the second mating part.

[0023] According to some embodiments of the present invention, before applying an outward-to-inward pressure to the edge of the elastic frame, the method further includes: Fold the elastic frame and wrap it. Release the wrapping of the elastic frame, the elastic frame unfolds elastically, and the mesh tightens.

[0024] The assembly method of this screen window involves folding the elastic frame and then wrapping it to fix the folded state of the elastic frame. This helps to reduce the space occupied by the elastic frame and facilitates its transportation. When it is necessary to assemble the elastic frame with the window frame, the user can unfold the wrapping of the elastic frame, thereby eliminating the constraint force of the wrapping on the elastic frame. Under the elasticity of the elastic frame itself, the elastic frame will recover its elasticity, and the screen will return to its taut state, thus easily connecting the elastic frame and the window frame.

[0032] The following is for reference. Figures 1 to 25 According to an embodiment of the present invention, a method for assembling a screen window can be conveniently connected to the window frame 300 through step design, reducing reliance on processing equipment and lowering transportation costs.

[0033] Understandably, see Figure 1 , Figure 2 , Figure 16 and Figure 17 According to an embodiment of the present invention, a method for assembling a window screen includes the following steps: S100 provides a screen 110, an elastic frame 120 and a window frame 300. The elastic frame 120 is arranged around the screen 110. The inner periphery of the elastic frame 120 is connected to the outer periphery of the screen 110 to drive the screen 110 to be tensioned. The window frame 300 is provided with a window 310. The window 310 is adapted to the elastic frame 120. The outer surface of the elastic frame 120 is connected with a first mating part, and the inner surface of the window 310 is provided with a second mating part. S200, apply pressure from the outside to the inside to the edge of the elastic frame 120, and place the deformed elastic frame 120 into the window 310, so that the first mating part and the second mating part are opposite to each other. S300, the pressure on the elastic frame 120 is released, and the elastic frame 120 expands outward elastically to drive the first mating part and the second mating part to be detachably connected.

[0034] See Figure 16 In step S100, the elastic frame 120 is square in shape, that is, the elastic frame 120 includes four side borders, namely the top side border, the left side border, the bottom side border and the right side border connected in sequence. The mesh 110 is located inside the elastic frame 120, and the outer periphery of the mesh 110 is connected to the inner periphery of the elastic frame 120. The elasticity of the elastic frame 120 is used to drive the mesh 110 to be taut, which helps to avoid the problem of the mesh 110 swaying greatly when blown by the wind. The mesh 110 has multiple mesh holes, which allow air exchange between indoors and outdoors. By controlling the mesh hole diameter, it can restrict mosquitoes from entering the room, which helps to create a suitable living environment for users.

[0035] The size and shape of the flexible frame 120 are adapted to the size and shape of the window frame 300. The flexible frame 120 can be made of a rigid material with good elasticity, such as metal.

[0036] See Figure 5 , Figure 6 , Figure 7 and Figure 8 Specifically, the elastic frame 120 includes four elastic strips 122, four sleeves 121, and four corner blocks 123. The upper, left, lower, and right edges of the mesh 110 are connected to the four sleeves 121, respectively. The sleeves 121 can be made of fabric pieces, specifically nylon fabric, fiber fabric, etc. The sleeves 121 can be glued to the mesh 110 to form a single unit. Each sleeve 121 has a through-hole cavity 1211. The elastic strips 122 are arranged in a one-to-one correspondence with the sleeves 121, and the length of the elastic strip 122 is greater than the length of the sleeve 121.

[0037] In step S100, the assembly method of the screen window, in which the outer surface of the elastic frame 120 is connected to a first mating part, further includes: S130, connect the top edge, left edge, bottom edge and right edge of the mesh 110 to the four strips 121 respectively; S140, the cavity 1211 through which the elastic strip 122 passes is set, and each of the two adjacent elastic strips 122 is connected to a corner block 123.

[0038] See Figure 5 and Figure 6In step S130, the sleeve 121 can be connected to the mesh 110 by adhesive bonding, and the inner edges of the four sleeves 121 can be connected to each other to enhance the connection stability of the four sleeves 121. The sleeves 121 can be formed into cavities 1211 through which the elastic strip 122 can pass by sewing or hot pressing of the fabric.

[0039] See Figure 7 , Figure 8 and Figure 9 In step S140, during assembly, the user can align the elastic strips 122 with the sleeves 121 one by one, and pass the elastic strips 122 through the cavity 1211. The ends of two adjacent elastic strips 122 are connected to a corner block 123. The corner block 123 has a first connecting hole and a second connecting hole, with the orientation of the first connecting hole and the orientation of the second connecting hole perpendicular to each other. Two adjacent elastic strips 122 are respectively inserted into the first and second connecting holes of a corner block 123. Under the connecting action of the corner block 123, the four elastic strips 122 form a square frame, and under the supporting action of the elastic strips 122, the mesh 110 connected to the sleeves 121 is taut.

[0040] See Figure 16 and Figure 17 In step S200, during assembly, the user can apply pressure from the outside to the inside to the edge of the elastic frame 120, thereby causing the edge of the elastic frame 120 to bend and deform inward, making it easier for the elastic frame 120 to fit with the window frame 300.

[0041] For example, a worker can apply pressure from the outside to the inside to the edge of the elastic frame 120, which can bring the left and right edges of the elastic frame 120 closer together, the top and bottom edges of the elastic frame 120 closer together, and reduce the included angle of the corners of the elastic frame 120, which is beneficial to shrink the elastic frame 120 inward so that the elastic frame 120 can be placed inside the window 310.

[0042] When the deformed elastic frame 120 is placed into the window 310, the user can apply pressure to the entire elastic frame 120 toward the window 310, so that the entire elastic frame 120 is inserted into the window 310, and the first mating part and the second mating part are positioned opposite each other.

[0043] See Figure 16 and Figure 17In step S300, after the user inserts the elastic frame 120 into the window 310, the user can release the pressure applied to the elastic frame 120. Under the elastic action of the elastic frame 120, the elastic frame 120 expands outward so that the first mating part and the second mating part can be detachably connected. That is, the screen window assembly method utilizes the outward elastic expansion of the elastic frame 120 and the detachable connection of the first mating part and the second mating part to realize the assembly of the screen 110 and the window frame 300.

[0044] Compared to the traditional screen 110 which is assembled with the frame through a strip pressing process, this modular screen window uses the elasticity of the elastic frame 120 to detachably connect the first and second mating parts. This allows the assembly of the elastic frame 120 and the window frame 300 to be carried out at the residence, eliminating the need for transporting the entire window, which helps reduce transportation costs. Furthermore, during transportation, the elasticity of the elastic frame 120 allows for folding and transport, reducing the transport volume of the elastic frame 120 and further lowering transportation costs. During assembly, the elasticity of the elastic frame 120 allows the screen 110 to quickly unfold and return to a taut state, making assembly simpler and more convenient.

[0045] In some other embodiments, the user may first insert one end of the elastic frame 120 into the window 310, and then apply pressure from the outside to the inside to the other end of the elastic frame 120, thereby deforming the elastic frame 120, and applying pressure close to the window frame 300 to the deformed elastic frame 120, so that the other end of the elastic frame 120 is also inserted into the window 310, thereby realizing the assembly of the elastic frame 120 and the window 310.

[0046] See Figure 12 and Figure 13 It is understood that in this embodiment, the first mating part is a locking strip 210, and the second mating part is a locking groove 220 provided on the inner surface of the window frame 300. The length of the locking strip 210 is less than or equal to the length of the locking groove 220, and the width of the locking strip 210 is less than or equal to the width of the locking groove 220, so that after the locking strip 210 and the locking groove 220 are aligned, under the elastic action of the elastic frame 120, the locking strip 210 can be driven to be inserted into the locking groove 220, which is beneficial to the assembly of the elastic frame 120 and the window frame 300.

[0047] See Figure 13The upper, left, lower, and right sides of the elastic frame 120 are all connected with retaining strips 210. The corresponding retaining grooves 220 are recessed outwards. When the elastic frame 120 is pressed inwards, it can be placed inside the window frame 300, and the retaining strips 210 are positioned opposite to the retaining grooves 220 on the inner surface of the window frame 300. After the pressure on the elastic frame 120 is released, under the elastic recovery of the elastic frame 120, the retaining strips 210 at the four sides of the elastic frame 120 expand outwards, so that the retaining strips 210 at the four sides of the elastic frame 120 are all inserted into the retaining grooves 220, so as to facilitate the assembly of the elastic frame 120 and the window frame 300. Since the four sides of the elastic frame 120 are all connected to the retaining grooves 220 through the retaining strips 210, it is beneficial to improve the connection stability between the elastic frame 120 and the window frame 300 and to reduce the risk of the elastic frame 120 falling out of the window 310 due to the influence of wind in the external environment.

[0048] Considering that some users live on higher floors, experience strong winds or extreme weather conditions, or have large screens, this modular screen has locking strips 210 connected to all four sides of the elastic frame 120. These strips, combined with the elasticity of the elastic frame 120, help to limit the mutual positioning of the elastic frame 120 and the window frame 300, thereby preventing the elastic frame 120 from coming off the window frame 300 and falling down.

[0049] It should be understood that in some other embodiments, the first mating part is a snap plate with a snap hole, and the second mating part is a limiting post. During assembly, the user can apply inward pressure to the elastic frame 120 to deform the elastic frame 120 inward and snap the elastic frame 120 into the window 310. The limiting post is opposite to the snap hole. After releasing the pressure on the elastic frame 120, the snap plate abuts against the inner surface of the window frame 300, and the limiting post passes through the snap hole, thereby realizing the detachable connection between the elastic frame 120 and the window frame 300.

[0050] It is understood that in this embodiment, the end closer to the indoor area is described as the rear end, and the end closer to the outdoor area is described as the rear end.

[0051] See Figure 10 and Figure 11Considering that during the assembly of the elastic frame 120 and the window frame 300, the first mating part will hinder the insertion of the elastic frame 120 into the window 310, it is necessary to squeeze the elastic frame 120. This makes the insertion of the elastic frame 120 into the window 310 relatively difficult, especially since the corners of the elastic frame 120 are difficult to retract and fit into the window 310. The window frame 300 provided in this embodiment is square-shaped, with rearward-opening notches 320 at each of its four corners. Specifically, the window frame 300 includes four frame strips 360 connected in sequence to form a square frame. Adjacent frame strips 360 can be connected by screws, and notches 320 are provided between adjacent frame strips 360.

[0052] See Figure 2 It is understandable that placing the deformed elastic frame 120 into the window 310 also includes: S210, the corners of the elastic frame 120 are aligned with the notch 320, and pressure is applied to the elastic frame 120 toward the window frame 300. The corners of the elastic frame 120 pass through the notch 320 and are placed inside the window 310.

[0053] See Figure 12 , Figure 16 and Figure 17 In step S210, when assembling the elastic frame 120 and the window frame 300, the user can press the edge of the elastic frame 120 inward to deform the corners of the elastic frame 120, reduce the included angle of the corners of the elastic frame 120, and align the corners of the elastic frame 120 with the notch 320. Then, the user can apply pressure to the elastic frame 120 toward the window frame 300 so that the corners of the elastic frame 120 can pass through the notch 320 and be inserted into the window 310, and the locking strip 210 can be embedded in the slot 220, thereby realizing the assembly of the elastic frame 120 and the window frame 300. Under the elastic recovery of the elastic frame 120, the locking strip 210 and the slot 220 are engaged, thereby realizing a stable connection between the elastic frame 120 and the window frame 300.

[0054] Understandably, see Figure 16 and Figure 17 Considering that when assembling the elastic frame 120 with the window frame 300, the user needs to squeeze the elastic frame 120 inward so that the elastic frame 120 can be inserted into the window 310, the ends of the upper, left, lower and right sides of the elastic frame 120 all protrude through the retaining strip 210, that is, the ends of the upper, left, lower and right sides of the elastic frame 120 are exposed relative to the retaining strip 210.

[0055] Taking the left border of the elastic frame 120 as an example, the upper end of the left border is located above the upper end of the corresponding card strip 210, and the lower end of the left border is located below the lower end of the corresponding card strip 210. The positional relationship between the upper border, lower border, and right border and the card strip 210 is similar to the positional relationship between the left border and the card strip 210, and will not be described again.

[0056] Both ends of the frame of the elastic frame 120 have the retaining strips 210 extending out, which helps to reduce the obstruction of the retaining strips 210 to the deformation of the corners of the elastic frame 120. When the four frames of the elastic frame 120 are pressed inward, it helps to increase the deformation range of the corners of the elastic frame 120, so that the angle of the corners of the elastic frame 120 is reduced, so that the corners of the elastic frame 120 can pass through the notch 320 of the window frame 300 and be inserted into the corner of the window frame 300, thereby realizing the detachable connection between the first mating part and the second mating part, as well as the adaptive connection between the elastic frame 120 and the window frame 300.

[0057] Multiple retaining strips 210 are connected to the upper, left, lower, or right side of the elastic frame 120, which helps to ensure the connection stability between the elastic frame 120 and the window frame 300. Specifically, two retaining strips 210 arranged at left and right intervals are connected to the upper and lower sides of the elastic frame 120. The spacing between the two retaining strips 210 on the upper or lower side of the elastic frame 120 helps to increase the deformability of the corresponding frame. During assembly, the user can apply pressure to the elastic frame 120 at the spacing between the two retaining strips 210, thereby causing the frame of the elastic frame 120 to deform inward, so as to increase the inward compression deformation range of the elastic frame 120 and realize the assembly with the window frame 300.

[0058] Understandably, see Figure 7 and Figure 8 The corner block 123 also includes a through groove, the first connecting hole and the second connecting hole are interconnected, the through groove is located on the inner surface of the corner block 123, the first connecting hole and the second connecting hole are both connected to the through groove, and the two ends of the through groove pass through the two ends of the corner block 123 respectively.

[0059] The through slot can effectively improve the deformation capability of the elastic frame 120. When the user applies pressure from the outside to the inside to the elastic frame 120, the two ends of the corner block 123 move closer to each other, that is, the included angle of the corner of the elastic frame 120 gradually decreases, so that the corner of the elastic frame 120 can pass through the notch 320 and fit into the window 310, so as to realize the adaptation connection between the elastic frame 120 and the window 310.

[0060] It is understandable that the following explanation will use the end closer to the indoors as the rear end and the end closer to the outdoors as the front end.

[0061] See Figure 12 and Figure 20The inner surface of the window frame 300 is provided with a limiting groove that opens backward and inward. The limiting groove has a bottom wall 330 and a side wall 340 arranged at right angles. The slot 220 is provided at the bottom wall 330. The locking strip 210 has a first wall surface 217 and a second wall surface 218 arranged at right angles. The first wall surface 217 abuts against the bottom wall 330, and the second wall surface 218 abuts against the side wall 340.

[0062] The assembly method of this screen window, in step S200, to drive the first mating part and the second mating part to be detachably connected, includes: S220, the card strip 210 is fitted into the card slot 220, and the first wall surface 217 abuts against the bottom wall 330, and the second wall surface 218 abuts against the side wall 340.

[0063] In step S220, considering the influence of windy, rainy, or extreme weather, the outdoor air velocity is relatively high, and the screen window tends to move outwards. The end closer to the interior is designated as the rear end, and the end closer to the exterior as the front end. The screen window assembly method features an inwardly opening limiting groove on the inner surface of the window frame 300. A locking groove 220 is located at the bottom wall 330 of the limiting groove. When the locking strip 210 engages with the locking groove 220, the elastic expansion of the elastic frame 120 allows the first wall surface 217 to abut against the bottom wall 330, preventing the locking strip 210 from dislodging inwards from the locking groove 220 and thus limiting the movement of the elastic frame 120 in the vertical plane. The second wall surface 218 abuts against the side wall 340, preventing the locking strip 210 from dislodging forward from the locking groove 220 and thus limiting the movement of the elastic frame 120 in the horizontal plane. This effectively improves the connection stability between the elastic frame 120 and the window frame 300, reducing the risk of the elastic frame 120 falling off.

[0064] See Figure 3 , Figure 18 and Figure 19 Understandably, the assembly method for this screen window also includes: S400 provides a cover plate 400 and a baffle plate 500, with the front end of the cover plate 400 connected to the baffle plate 500; S500, the cover plate 400 is placed behind the limiting groove, the cover plate 400 is detachably connected to the rear end of the window frame 300, and the baffle 500 is at least partially located inside the retaining strip 210.

[0065] In step S400, the assembled screen window also includes four cover plates 400, which are respectively set to correspond to the four frame strips 360 of the window frame 300. Correspondingly, each of the four frame strips 360 is provided with a limiting groove that opens backward and inward.

[0066] In step S500, the cover plate 400 is detachably connected to the rear end of the window frame 300 and covers the rear of the locking strip 210. In use, after the user inserts the elastic frame 120 into the window 310 and completes the engagement of the locking strip 210 and the slot 220, the user can connect the cover plate 400 to the rear end of the window frame 300. The cover plate 400 can close the notch 320 at the corner of the window frame 300, so that the locking strip 210 is hidden between the cover plate 400 and the window frame 300, which helps to maintain the flatness of the assembled screen window.

[0067] After the cover plate 400 is connected to the rear end of the window frame 300, it is beneficial to close the rear end opening of the limiting groove, which helps to limit the elastic frame 120 from falling out of the window 310, and helps to limit the displacement of the elastic frame 120 and the window frame 300 in the horizontal plane, which helps to reduce the risk of the elastic frame 120 falling off.

[0068] The front end of the cover plate 400 is connected to a baffle 500. Specifically, the cover plate 400 and the baffle 500 are arranged at right angles, and the baffle 500 is at least partially located on the inner side of the retaining strip 210. The baffle 500 can abut against the inner surface of the retaining strip 210, thereby restricting the retaining strip 210 from dislodging from the retaining groove 220, which helps to improve the connection stability between the elastic frame 120 and the window frame 300.

[0069] Furthermore, when the cover plate 400 is detachably connected to the rear end of the window frame 300, the cover plate 400 can seal the notch 320 at the corner of the window frame 300, thereby preventing the elastic frame 120 from detaching from the window frame 300 and helping to maintain the flatness of the window frame 300's shape. To maintain the consistency of the entire window, the cover plate 400 and the window frame 300 can be made of the same material; for example, both the cover plate 400 and the window frame 300 can be made of aluminum.

[0070] See Figure 12 and Figure 20 It is understandable that, specifically, the rear end face of the window frame 300 is provided with a rearward-opening hook groove 350. Specifically, each of the four frame strips 360 is provided with a rearward-opening hook groove 350. The hook groove 350 is provided with a first barb 351 near the inner wall surface, and the hook part of the first barb 351 is set outward.

[0071] The cover plate 400 is connected to a forward-extending second barb 410, which can be inserted into the hook groove 350. The hook part of the second barb 410 is set inward, that is, the hook part of the second barb 410 is set opposite to the hook part of the first barb 351. When the second barb 410 is inserted to a certain depth in the hook groove 350, the second barb 410 and the first barb 351 can be engaged to realize the detachable connection between the cover plate 400 and the window frame 300. It is also beneficial to realize the concealment of the connection between the cover plate 400 and the window frame 300. That is, the second barb 410 is inserted into the hook groove 350, and the cover plate 400 can close the opening of the hook groove 350, which helps to improve the flatness of the assembled screen window.

[0072] Specifically, the inner edge of the cover plate 400 is flush with the inner edge of the second circumferential piece 213 of the locking strip 210, which facilitates the concealment of the locking strip 210, ensuring that the locking strip 210 cannot be observed by the user indoors or outdoors, and helps maintain the flatness of the assembled screen window. Two baffles 500 are provided, meaning each cover plate 400 is connected to two baffles 500. The two baffles 500 located on the same cover plate 400 are spaced vertically, which helps to limit the locking strip 210, preventing the locking strip 210 from coming out of the slot 220. The baffles 500 also help to conceal the locking strip 210.

[0073] See Figure 13 , Figure 14 and Figure 15 It is understood that the card strip 210 includes a connecting piece 211, a first surrounding piece 212, a second surrounding piece 213 and an insert piece 216. The first surrounding piece 212, the connecting piece 211 and the second surrounding piece 213 are connected in sequence to form a groove 215. At least one of the first surrounding piece 212 and the second surrounding piece 213 is provided with a protruding edge 214 that protrudes toward the groove 215.

[0074] The insert 216 is located at the end of the connecting piece 211 away from the groove 215. When the elastic frame 120 is squeezed and deformed inward and inserted into the window 310, the retaining strip 210 expands outward under the elastic action of the elastic frame 120, and the insert 216 of the retaining strip 210 fits into the groove 220, thereby realizing the assembly of the elastic frame 120 and the window frame 300.

[0075] Specifically, the first wall surface 217 is the end face of the connecting piece 211 near the insert piece 216, while the second wall surface 218 is the side of the second circumferential piece 213 away from the groove 215. When the retaining strip 210 is engaged with the groove 220, the connecting piece 211 abuts against the bottom wall 330, and the second circumferential piece 213 abuts against the side wall 340, thereby improving the connection stability between the elastic frame 120 and the window frame 300. The inner edge of the second wall surface 218 is flush with the inner edge of the side wall 340, which helps to increase the contact area between the second wall surface 218 and the side wall 340, thereby improving the connection stability between the elastic frame 120 and the window frame 300, and also helps to prevent the elastic frame 120 from coming out of the groove 215.

[0076] See Figure 4 It is understood that in step 100, the outer surface of the elastic frame 120 is connected to a first mating part, including: S110, align the opening of the groove 215 with the edge of the elastic frame 120, and rotate the retaining strip 210 in the first direction to drive the edge portion of the elastic frame 120 into the groove 215. S120, the retaining strip 210 is rotated in the opposite direction in the first direction, and pressure is applied to the retaining strip 210 toward the elastic frame 120 so that the edge of the elastic frame 120 is engaged with the groove 215, and the protrusion 214 abuts against the inner surface of the elastic frame 120.

[0077] In step S110, when connecting the card strip 210 and the elastic frame 120, the user can first align the opening of the groove 215 of the card strip 210 with the edge of the elastic frame 120, and rotate the card strip 210 in the first direction so that the edge of the elastic frame 120 moves closer to the groove 215, so that the edge part of the elastic frame 120 is placed in the groove 215, and the protruding edge 214 of the card strip 210 is rotated to the inside of the elastic frame 120.

[0078] In step S120, the user then rotates the card strip 210 in the opposite direction of the first direction and applies pressure to the card strip 210 toward the elastic frame 120, so that the protruding edge 214 of the card strip 210 hooks onto the inner surface of the elastic frame 120, and the edge of the elastic frame 120 engages with the groove 215, thereby restricting the elastic frame 120 from coming out of the groove 215, so as to improve the connection stability between the elastic frame 120 and the card strip 210.

[0079] Both the first wall surface 217 and the second wall surface 218 have protruding edges 214 at their ends near the window 310, which can, to a certain extent, restrict the elastic frame 120 from coming out of the groove 215.

[0080] Understandably, the assembly method of this screen window, before applying outward-inward pressure to the edge of the elastic frame 120, also includes: S600, fold the elastic frame 120 and wrap the elastic frame 120; S700, release the wrapping of the elastic frame 120, the elastic frame 120 unfolds elastically, and the mesh 110 is tensioned.

[0081] In step S600, the screen window assembly method can fix the folded state of the elastic frame 120 by folding the elastic frame 120 and wrapping the folded elastic frame 120. This helps to reduce the space occupied by the elastic frame 120 and facilitates the transportation of the elastic frame 120.

[0082] See Figures 21 to 25 Specifically, when it is necessary to fold the flexible frame by 120... Users can apply opposing squeezing forces to the left and right sides of the elastic frame 120 respectively, so that the left and right sides of the elastic frame 120 move inward. Then the user can hold the left and right sides of the elastic frame 120 with one hand at the same time, and then use the other hand to fold the top and bottom sides of the elastic frame 120 to the middle of the elastic frame 120. Then, by folding the elastic frame 120 vertically and horizontally, the elastic frame 120 is folded to one-quarter of its original size. The flexible frame 120, when folded and wrapped with packaging straps, facilitates folding and transportation.

[0083] In step S700, when it is necessary to assemble the elastic frame 120 and the window frame 300, the user can unwrap the elastic frame 120 to eliminate the constraint force caused by the wrapping. Under the elastic action of the elastic frame 120 itself, the elastic frame 120 will recover its elasticity and the screen 110 will return to its tensioned state, thus conveniently connecting the elastic frame 120 and the window frame 300.

[0084] The above are merely preferred embodiments of the present invention and do not limit the scope of the patent. Any equivalent structural transformations made using the contents of the specification and drawings of the present invention under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the scope of patent protection of the present invention.
