[0027] like Figure 1 As shown in the figure, this utility model provides a multi-directional adjustable window dustproof net support device, including support rods 1 and inner sleeves 3. Two support rods 1 are arranged in an X-shape, with a connecting shaft 2 at the intersection. The connecting shaft 2 passes through the middle of the two support rods 1 and is rotatably connected to them, allowing the included angle between the two support rods 1 to be adjusted, suitable for windows of different shapes. The inner sleeve 3 is located at both ends of the support rods 1, with one end fitted inside the support rod 1 and the other end extending out of the support rod 1 and abutting against the window frame 10. The inner sleeve 3 can move along the support rod 1 and is detachably connected to it. The length of the inner sleeve 3 extending out of the support rod 1 can be adjusted according to the size of the window. A dustproof net 4 is connected to the extended end of the inner sleeve 3. By abutting the extended end of the inner sleeve 3 against the window frame 10, the entire support device can be fixed to the window frame 10 without drilling holes in the concrete window frame 10 or plastered wall, simplifying operation and avoiding structural damage.

[0028] Preferably, the extended end of the inner sleeve 3 is provided with a window support ball 5, which abuts against the window frame 10. The window support ball 5 is a metal sphere structure and is fixedly connected to the extended end of the inner sleeve 3. By providing the window support ball 5, when the extended end of the inner sleeve 3 abuts against the corner of the window frame 10, the adjacent two sides of the window frame 10 can simultaneously abut against the window support ball 5, making the abutment and engagement more secure.

[0029] Preferably, a protective plate 6 is provided on the side of the window support ball 5 near the inner side of the window frame 10. The protective plate 6 extends to the outer edge of the window frame 10, and a dustproof net 4 is connected to the protective plate 6. The protective plate 6 is set parallel to the inner wall of the window, with one end fixedly connected to the window support ball 5 and the other end extending to the outer edge of the window frame 10. By setting the protective plate 6, when the entire support device moves outward under the action of external force, the protective plate 6 abuts against the inner wall of the window, which can prevent the support device from falling off the window. Preferably, the protective plate 6 is set as a long strip, extending along the length direction of the inner sleeve 3 and the support rod 1.

[0030] The four corners of the dustproof net 4 are connected to the protective plate 6, which can be done by rivets or by using cable ties to tie the four corners of the dustproof net 4 to the protective plate 6.

[0031] Preferably, the protective plate 6 has a slot (not shown in the figure), and the dustproof net 4 is detachably connected to the slot. When using cable ties for binding, to prevent the cable ties from moving on the protective plate 6, the protective plate 6 has a slot. The cable ties are bound in the slot, and the slot limits the movement of the cable ties.

[0032] Specifically, fasteners are provided on the connecting shaft 2, allowing the support rod 1 to be detachably connected to the connecting shaft 2, which is not shown in the figure. When supporting the dustproof net 4, the fasteners secure the two intersecting support rods 1 to the connecting shaft 2 together, making the entire support device more stable. When it is necessary to adjust the angle of the support rod 1 according to the size of the window frame 10, simply loosen the fasteners and rotate the two support rods 1.

[0033] Preferably, the connecting shaft 2 is a bolt, and the fastener is a wing nut. The two cross-shaped support rods 1 have through holes in their middle sections, through which the bolt passes, allowing the support rods 1 to rotate around the bolt. The wing nut is inserted into the bolt; tightening the wing nut secures the two support rods 1 to the bolt.

[0034] In some embodiments, such as Figure 2 As shown, the end of the support rod 1 is equipped with a latch 7, which is detachably connected to the inner sleeve 3. The latch 7 includes a threaded sleeve and a nut. One end of the support rod 1 near the inner sleeve 3 is inserted into one end of the threaded sleeve and fixedly connected to the unthreaded end of the threaded sleeve. The threaded end of the threaded sleeve is fitted over the outside of the inner sleeve 3 and tightened with the nut to position the inner sleeve 3. The latch 7 is existing technology, made of plastic, and is typically used for positioning telescopic rods. Its specific structure and connection method will not be described in detail here.

[0035] In some embodiments, such as Figure 3As shown, the end of the support rod 1 is provided with a positioning pin 8, and the inner sleeve 3 is provided with multiple positioning holes 9. The positioning pin 8 is detachably connected to the positioning holes 9. Specifically, the positioning pin 8 is set as a positioning bolt, which is detachably connected to the support rod 1. Multiple positioning holes 9 are provided at equal intervals along the length of the inner sleeve 3. The positioning bolt passes through the positioning holes 9 and is detachably connected with a nut. By connecting with different positioning holes 9, the length of the inner sleeve 3 extending into the support rod 1 can be adjusted, so that the support device can be used for windows of different sizes.

[0036] A method for using a multi-directional adjustable window dustproof net support device as described above includes the following steps:

[0037] Loosen the fasteners and rotate support rod 1 so that the two support rods 1 are positioned diagonally across the window.

[0038] Loosen the nut or positioning pin 8 of the locking buckle 7 on the support rod 1, move the inner sleeve 3 along the support rod 1, and adjust the length of the inner sleeve 3 extending out of the support rod 1 so that the window support ball 5 abuts against the four corners of the window.

[0039] After adjusting the angle of the support rod 1 and the extension length of the inner sleeve 3, tighten the fasteners and lock the inner sleeve 3 to the support rod 1.

[0040] Lay the dustproof net 4 flat to cover the outside of the protective plate 6, leaving a 50mm margin at the edge, and use rivets or cable ties to connect the four corners of the dustproof net 4 to the protective plate 6.
