[0158] Example 2

[0159] like Figure 16-19 As shown, this embodiment also discloses an easy-to-assemble and disassemble screen window, including the retractable sliding screen window assembly described in Embodiment 1, an upper frame 40, a lower frame 50, a left frame 60, a right frame 70, an upward sliding window 80, and a downward sliding window 90, wherein:

[0160] The upper frame 40, left frame 60, lower frame 50, and right frame 70 together form an integral screen window frame;

[0161] The upward-pushing window 80 is fixed to the upper part of the overall screen window frame;

[0162] The push-down window 90 can move up and down, and when the push-down window 90 moves up a distance greater than the height of the left hand-held part 101 of the first screen or the right hand-held part 201 of the second screen, the retractable push-pull screen assembly can be taken out.

[0163] The retractable sliding screen assembly is placed in the groove of the lower frame 50, and both ends, or one end of the retractable sliding screen assembly, are simultaneously embedded in the grooves inside the left frame 60 and / or the right frame 70. The lower edge of the push-down window 90 presses against the upper crossbar 102 of the first screen and the upper crossbar 202 of the second screen, thereby fixing the retractable sliding screen assembly and placing it in an open or closed state.

[0164] Specific working principle:

[0165] refer to Figure 16-19 The installation process is shown in sequence: the initial state of the easy-to-install and disassemble screen window, component placement, component positioning, and final fixation. Push the down-pull window 90 upwards by a distance greater than the height of the left handle 101 of the first screen window (or the right handle 201 of the second screen window) by 1-2 cm. This distance ensures that the retractable sliding screen window component can be placed or removed smoothly while avoiding excessive movement of the down-pull window 90, which would affect the ease of operation. The retractable sliding screen window component is placed in the groove of the lower frame 50 and embedded in the groove inside the right frame 70. Pull the left handle 101 of the first screen window to the left, so that the left handle 101 of the first screen window is embedded in the groove inside the left frame 60. Then, press the lower edge of the down-pull window 90 above the upper crossbar 102 of the first screen window and the upper crossbar 202 of the second screen window to complete the installation process of the screen window.

[0166] Conversely, to open the screen window, first push the lower sliding window 90 upwards so that its lower edge is no longer pressing against the top of the first screen window's upper horizontal bar 102 and the second screen window's upper horizontal bar 202. Then, move the left-side handle 101 of the first screen window to the right a certain distance to disengage it from the groove inside the left frame 60, or move the right-side handle 201 of the second screen window to the left a certain distance to disengage it from the groove inside the right frame 70. Finally, press the lower edge of the lower sliding window 90 back onto the top of the first screen window's upper horizontal bar 102 and the second screen window's upper horizontal bar 202 to open the screen window. To remove the screen window, simply detach and remove the retractable sliding screen window assembly to complete the removal process.

[0167] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
