[0023] In order to make the technical solution of the utility model more clear and specific to those skilled in the art, the utility model is further described in detail below in conjunction with embodiments and drawings, but the implementation methods of the utility model are not limited thereto.

[0024] like Figure 1 , Figure 3 and Figure 4 As shown, the present embodiment provides an anti-theft system door and window, including a door and window outer frame 1, a window door 2 is hingedly installed on the inner side of the door and window outer frame 1, and the window door 2 is an inward opening type. A first rolling rod 3 is rotatably installed on the inner top of the door and window outer frame 1 along the length direction, and a steel wire protection net 4 is wound and installed on the first rolling rod 3. The steel wire protection net 4 has large mesh holes for anti-theft and ensures air permeability during use. A second rolling rod 5 is rotatably installed at the horizontal position of the first rolling rod 3 on the inner top of the door and window outer frame 1, and a metal mosquito-proof net 6 is wound and installed on the second rolling rod 5. During use, mosquitoes are protected and prevented from entering. The mesh holes on the steel wire protection net 4 are larger than the mesh holes on the metal mosquito-proof net 6. Since the mesh holes of the metal mosquito-proof net 6 are small, they will also block natural wind. Therefore, during ventilation, the metal mosquito-proof net 6 can be selected to be folded and the steel wire protection net 4 can be unfolded for use. The steel wire protection net 4 is located on the side close to the outdoors, and the metal mosquito-proof net 6 is located on the side close to the indoors.

[0025] like Figure 1 As shown, the same end of the first winding rod 3 and the second winding rod 5 are fixedly installed with a gear 8, and the gears 8 are meshed with each other. The bottom ends of the steel wire protection net 4 and the metal mosquito-proof net 6 are fixedly installed with a limiting plate 7 along the length direction of the door and window outer frame 1. During use, the steel wire protection net 4 or the metal mosquito-proof net 6 is selected, and then the limiting plate 7 at the bottom is held to pull down and fix the steel wire protection net 4 or the metal mosquito-proof net 6. When the steel wire protection net 4 and the metal mosquito-proof net 6 are replaced, since the gears 8 at the ends of the first winding rod 3 and the second winding rod 5 are meshed with each other, the metal mosquito-proof net 6 is automatically rolled up when the steel wire protection net 4 is unfolded, or the metal mosquito-proof net 6 is unfolded and the steel wire protection net 4 is automatically rolled up, so the replacement is more convenient;

[0026] like Figure 2 As shown, the inner walls on both sides of the door and window outer frame 1 are provided with a slide groove 12, and both ends of the limiting plate 7 are located inside the slide groove 12, which can limit the position of the limiting plate 7, and both ends of the steel wire protection net 4 and the metal mosquito-proof net 6 pass through the inside of the slide groove 12, and both ends of the steel wire protection net 4 and the metal mosquito-proof net 6 are evenly fixed with cone blocks 13, and the cone blocks 13 are all located inside the door and window outer frame 1. When the steel wire protection net 4 or the metal mosquito-proof net 6 is pulled down and released, the steel wire protection net 4 or the metal mosquito-proof net 6 passes through the inside of the slide groove 12, and the cone blocks 13 at the ends thereof are attached to the inner side of the slide groove 12, so as to limit the ends of the steel wire protection net 4 or the metal mosquito-proof net 6, and ensure the stable installation of the steel wire protection net 4 or the metal mosquito-proof net 6;

[0027] like Figure 1 As shown, a fixing mechanism is provided between the limit plate 7 and the inner bottom of the door and window outer frame 1, and the fixing mechanism includes a slot 9, a through hole 10 and a limit rod 11. The slot 9 is opened at the inner bottom of the door and window outer frame 1 along the length direction of the door and window outer frame 1. When the wire protection net 4 or the metal mosquito net 6 is in use, the limit plate 7 at its bottom will be inserted into the inside of the slot 9, and the through hole 10 is opened on the limit plate 7. The limit rod 11 is slidably installed at the bottom of the door and window outer frame 1 close to the indoor side, and the limit rod 11 passes through the slot 9. After the limit plate 7 is inserted into the inside of the slot 9, the limit rod 11 is passed through the through hole 10 to position the limit plate 7. A pull block is fixedly installed at one end of the limit rod 11 close to the indoor room to facilitate controlling the sliding of the limit rod 11. A limit block is provided at the middle position of the limit rod 11 inside the door and window outer frame 1 to avoid excessive stretching of the limit rod 11.

[0028] The above is only a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the scope disclosed by the present invention according to the technical solution and concept of the present invention, which fall within the protection scope of the present invention.
