Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0037] The principle of the present invention is to describe a form of adding a foldable sunshade system to the exterior windows of existing residential buildings. The purpose is to set an H-shaped steel slide rail and a pulley, and then drive the pulley to move up and down by manpower or electrical devices, thereby driving the exterior sunshade system to move up and down and in and out, so as to change the sunshade area.

[0038] This foldable sunshade system is divided into a sunshade panel system, an H-shaped steel slide rail, and a pulley system. The sunshade panel system is divided into two parts, the upper and lower parts are connected by a stainless steel hinge. The upper part of the panel system is bolted to the horizontal steel beam on the upper part of the window outer side, and the lower part of the panel system is connected to the pulley system by bolts. There is a pulley on the outside of the pulley system that slides on the H-shaped steel slide rail surface, and there are two U-shaped grooves on the inside that are stuck in the two flange plates of the H-shaped steel. By fine-tuning the gap between the two U-shaped grooves and the flange plates, it is ensured that the pulley is in close contact with the H-shaped steel slide rail surface and slides freely. The vertical H-shaped steel slide rail can be welded to the two horizontal steel beams on the upper and lower parts of the window outer side. The two upper and lower horizontal steel beams need to be reliably connected to the main structure.

[0040] like Figure 3 and 6 As shown, the sunshade system also includes an H-shaped steel slide rail 2 and a pulley structure 3. The H-shaped steel slide rail 2 is fixed between the upper steel beam 5 and the lower steel beam 6. The pulley structure 3 is installed on the H-shaped steel slide rail 2 and connected to the lower sunshade panel 12. The pulley structure 3 slides on the H-shaped steel slide rail 2 and drives the lower sunshade panel 12 to rotate.

[0041] There are two sets of H-shaped steel slide rails 2 and pulley structures 3 respectively. The two sets of H-shaped steel slide rails 2 are arranged in parallel and are respectively located on the left and right sides of the sunshade panel 1, and the two sets of pulley structures 3 are respectively located at the lower position of the left and right sides of the sunshade panel 1.

[0042] The upper sunshade panel 11 is connected to the lower sunshade panel 12 via a stainless steel hinge 13 , and the upper sunshade panel 11 and the lower sunshade panel 12 can rotate freely around the hinge axis of the stainless steel hinge 13 .

[0045] like Figure 7 As shown, the pulley structure 3 includes a U-shaped steel guard plate 31, an ear plate connecting structure 32, a pulley fixing structure 33, a clamping structure 34 and a slot structure 35. The U-shaped steel guard plate 31 is connected to the lower steel ear plate 121 on the lower sunshade panel 12 through the ear plate connecting structure 32. The pulley fixing structure 33 is used to fix the pulley 331 on the U-shaped steel guard plate 31. The clamping structure 34 is used to fix the pulley structure 3 to a set position on the H-shaped steel slide rail 2. The slot structure 35 is used to make the pulley in close contact with the H-shaped steel slide rail 2 and slide freely.

[0046] Two steel ribs 37 are welded on the U-shaped steel guard plate 31 to increase the rigidity of the U-shaped steel guard plate 31 .

[0047] The ear plate connection structure 32 includes a lower stainless steel bolt 321 and a guard plate steel ear plate 322 . The guard plate steel ear plate 322 is welded to the U-shaped steel guard plate 31 . The guard plate steel ear plate 322 is connected to the lower steel ear plate 121 via the lower stainless steel bolt 321 .

[0048] The pulley fixing structure 33 includes a pulley 331 and a pulley connector 332 . The pulley connector 332 is fixed to the U-shaped steel guard plate 31 . The pulley 331 is connected to the pulley connector 332 by bolts.

[0049] The clamping structure 34 includes a clamping steel plate 341, a clamping bolt sleeve 342 and a clamping bolt 343. The clamping bolt 343 passes through the clamping steel plate 341, the clamping bolt sleeve 342 and the U-shaped steel guard plate 31 in sequence. The H-shaped steel slide rail 2 is arranged between the clamping steel plate 341 and the U-shaped steel guard plate 31. When the clamping bolt 343 is tightened, the clamping steel plate 341 and the U-shaped steel guard plate 31 clamp the H-shaped steel slide rail 2, thereby preventing the pulley structure 3 from sliding.

[0050] Each of the pulley structures 3 includes two sets of clamping structures 34 , and the two sets of clamping structures 34 are respectively arranged on both sides of the pulley 331 .

[0051] The pulley structure 3 also includes a limiting structure 36, which is used to position the pulley structure 3 to an accurate position; the clamping structure 34 is used in conjunction with the limiting structure 36 to limit the pulley structure 3, the lower sunshade panel 12 and the upper sunshade panel 11 in the open state.

[0052] The limiting structure 36 includes a limiting bolt 361, a guard plate hole and a slide rail limiting hole. The slide rail limiting holes are a plurality of circular through holes provided on the side of the H-shaped steel slide rail 2. The limiting bolt 361 passes through the guard plate hole and the slide rail limiting hole in sequence.

[0053] The process of using the clamping structure 34 and the limiting structure 36 in coordination is as follows: loosening the nut of the clamping bolt 343 can allow the pulley structure 3 to slide on the H-shaped steel slide rail 2. After the pulley structure 3 slides to the vicinity of the limiting position, tighten the nut of the clamping bolt 343 to prevent the pulley structure 3 from sliding temporarily. Observe whether the limiting bolt 361 is consistent with the position of the corresponding circular limiting hole of the H-shaped steel slide rail 2. If not, loosen the nut of the clamping bolt 343, allow the pulley structure 3 to slide to the correct position, tighten the limiting bolt 361 and the clamping bolt 343, so that the pulley structure 3, the lower sunshade panel 12 and the upper sunshade panel system 11 are limited in this open state.

[0054] The slot structure 35 includes an L-shaped connector 351, a locking screw 352, a U-shaped slot 353, a friction-resistant gasket 354, an adjusting screw 355 and a screw sleeve 356. One end of the L-shaped connector 351 is connected to the U-shaped steel guard plate 31 through the locking screw 352, and the other end is connected to the U-shaped slot 353 through the adjusting screw 355 and the screw sleeve 356 in turn. The U-shaped slot 353 is clamped on the two flange plates of the H-shaped steel slide rail 2 through the friction-resistant gasket 354. The adjusting screw 355 is rotated to fine-tune the distance between the U-shaped slot 353 and the flange plate of the H-shaped steel slide rail 2, thereby ensuring that the pulley structure 3 slides up and down smoothly.

[0055] The anti-friction gasket 354 is coated with lubricant to reduce the friction noise between the U-shaped slot 353 and the H-shaped steel slide rail 2 and increase the smoothness of the up and down sliding.

[0056] Each of the pulley structures 3 comprises two sets of slot structures 35 , and the two sets of slot structures 35 are respectively arranged at two flange plates of the H-shaped steel slide rail 2 .

[0057] Therefore, the present invention improves the sunshade performance of the exterior window by adding a sunshade system outside the exterior window. At the same time, the present invention uses the up and down movement of the pulley to change the sunshade area and the distance between the sunshade system and the existing exterior window, so as to adjust the radiant heat of sunlight entering the room according to the needs of indoor users, improve the indoor living thermal environment, and reduce the energy consumption of air conditioning.
