[0037] Referring to Figures 4 - 11 , this embodiment provides a hook-to-hook assembly structure for a screen window, which mainly solves the problems that the screen mesh 1 is prone to falling off and is not firm after installation. This hook-to-hook assembly structure is achieved by tightly fitting the Z-shaped folding edge 11 of the screen mesh 1 with the groove 21 of the frame 2, and then using a pressing strip 3 to be inserted into the groove 21 to press the folding edge 11 of the screen mesh 1, enhancing the fixation between the screen mesh 1 and the frame.

[0038] As Figures 4 - 6 shows, specifically, first, the edge of the screen mesh 1 is bent into a Z shape and pressed into the groove 21 of the frame 2. The outer side of the groove 21 is provided with a folded edge 22 inward, and the folded edge 22 forms a hook-to-hook fit with the Z-shaped folding edge 11. Then, a pressing strip 3 is inserted into the groove 21 and pressed on the Z-shaped folding edge 11 of the screen mesh 1 to ensure that the folding edge 11 of the screen mesh 1 can be tightly attached to the groove 21 of the frame 2.

[0039] The fixing principle of the screen mesh 1 of this hook-to-hook assembly structure is as Figure 6As shown in the figure, without the pressing strip 3, when the screen mesh 1 is subjected to an upward pulling force, the first bending part 12 will be gradually pushed open by the folded edge 22 of the frame 2, causing the screen mesh to fall off. The presence of the pressing strip 3 can prevent this situation from occurring, ensuring that the first bending part 12 closely adheres to the folded edge 22, forming a stable hook-to-hook fit, similar to two hooks hooking together, which guarantees the stability of the assembly structure. In addition, this structure also simplifies the installation and disassembly process of the screen mesh 1. As long as the user installs or removes the pressing strip 3, it is more convenient to install and disassemble the screen mesh 1, which not only ensures the structural integrity of the screen mesh 1 but also improves the service life of the screen mesh.

[0040] The specific structure of the hook-to-hook assembly of the screen mesh 1 and the groove 21 is as follows:

[0041] The screen mesh 1 is divided into a first bending part 12 and a second bending part 13 by the Z-shaped folding edge 11. Among them, the first bending part 12 hooks on the folded edge 22, the second bending part 13 is stuck in the groove 21 by the pressing strip 3, and the second bending part 13 is pressed against the bottom of the groove 21.

[0042] For the groove 21 of the frame 2, its outer side forms a side inner groove 23 with the folded edge 22 and the groove 21 body. When the pressing strip 3 is inserted into the groove 21, one side of the pressing strip 3 is stuck in the side inner groove 23 and presses the first bending part 12 on the folded edge 22, so that the first bending part hooks on the folded edge 22.

[0043] In addition, in this embodiment, aesthetics is also considered. Therefore, the groove 21 is arranged on the outer side of the frame 2, and the notch of the groove 21 is designed to face the outside. Such a design not only effectively avoids the problem of the screen mesh 1 falling off caused by improper installation of the pressing strip 3 but also ensures the neat appearance of the screen window and does not affect the beauty of the interior.

[0044] The first embodiment is as Figure 7 。

[0045] Provide an installation structure for the pressing strip 3.

[0046] One side of the pressing strip 3 for being stuck in the side inner groove 23 is provided with a card slot 31, and a first pressing edge 32 and a second pressing edge 33 are vertically arranged with the card slot 31. When the pressing strip 3 is stuck in the groove 21, the card slot 31 forms a pull-out type clamping fit with the folded edge 22, and the first pressing edge 32 is stuck in the side inner groove 23 to form an extrusion fixation for the first bending part, and the second pressing edge 33 presses on the upper side of the folded edge 22. The first pressing edge 32 and the second pressing edge 33 are used to press the first bending part 12 so that the first bending part 12 hooks on the folded edge 22. The second pressing edge 33 plays an effect of sealing the edge and making it beautiful.

[0047] The second embodiment is as Figures 8 - 9 。

[0048] Provide another installation structure for the bead 3.

[0049] The bead 3 is strip-shaped. The bead 3 is inserted into the groove 21, and the whole bead 3 is placed inside the groove 21. One side of the bead 3 is snapped into the side inner groove 23 to press the first bent portion 12 tightly against the hem 22.

[0050] In the second embodiment, a structure of the decorative strip 4 is also provided. The frame 2 includes the decorative strip 4. Since the whole bead 3 is placed inside the groove 21, the decorative strip 4 is covered on the notch of the groove 21 to achieve the effect of edge sealing and aesthetics.

[0051] The structure of the decorative strip 4 is designed such that one side of the decorative strip 4 is provided with a U-shaped bayonet 41. The upper side of the U-shaped bayonet 41 is provided with a third bead 42, and the lower side of the U-shaped bayonet 41 is provided with a clamping edge 43. The third bead 42 presses on the hem 22 to form an edge seal. One side of the bead 3 is clamped below the hem 22, and there is a gap between this side and the hem 22. This gap is used for the clamping edge 43 to snap in and form a fixation.

[0052] The above is only a preferred specific embodiment of the present invention, but the design concept of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, making non-substantive modifications to the present invention using this concept, shall fall within the scope of infringement of the protection of the present invention.
