[0034] The present invention is further described below with reference to specific embodiments. Figure 1 —5:

[0035] Example 1: See Figure 1-4 :

[0036] A three-proof window for a granary comprises an outer window frame 1 and an inner window frame 2 arranged inside the outer window frame 1, a vent 3 being provided in the middle of the inner window frame 2, a bird-proof window frame 4 being provided at the vent 3, a bird-proof window frame 4 being provided inside the bird-proof window frame 4, an insect-proof window frame 6 being detachably connected to the bird-proof window frame 4, the insect-proof window frame 6 being located in front of the bird-proof net 5, an insect-proof net 7 being provided inside the insect-proof window frame 6, a sealing plate 8 being provided at the window of the outer window frame 1, and the sealing plate 8 being located in front of the insect-proof window frame 6.

[0037] The working principle of the present invention is as follows: when sealing is required, the sealing plate 8 is closed, as shown in FIG. Figure 1 When a certain ventilation effect is required, but insect protection is required, open the sealing plate 8, install the bird-proof window frame 4 and the insect-proof window frame 6, as Figure 2 When greater ventilation effect is required, but bird protection is required, open the sealing plate 8 to remove the insect-proof window frame 6, install the bird-proof window frame 4, as Figure 3 When maximum ventilation is required, open the sealing plate 8 and the bird-proof window frame 4, remove the insect-proof window frame 6, as Figure 4 shown.

[0038] The utility model arranges an inner window frame 2 in an outer window frame 1, a bird-proof window frame 4 in the inner window frame 2, an insect-proof window frame 6 on the bird-proof window frame 4, and a sealing plate 8 at the window of the outer window frame 1. When sealing is required, only the gap between the sealing plate 8 and the outer window frame 1 needs to be sealed, and the air leakage range is small, the air tightness is good, and the thermal insulation effect is good. When bird-proof ventilation is required, the insect-proof window frame 6 can be removed, and the ventilation effect is good. When complete ventilation is required, the ventilation area is large and the ventilation effect is good.

[0039] In order to achieve a better sealing effect between the outer window frame 1 and the sealing plate 8 and further improve the air tightness, a sealing strip 11 is provided on the inner window frame 2 to seal the gap between the outer window frame 1 and the sealing plate 8 .

[0040] The connection method between the sealing plate 8 and the outer window frame 1 is as follows: one side of the sealing plate 8 is hinged to the outer window frame 1 through a hinge, and the other side of the sealing plate 8 is detachably connected to the outer window frame 1 through a clamping handle 12 provided on the sealing plate 8 and a fixing buckle 13 provided on the outer window frame 1.

[0041] In order to save space in front of the bird-proof window frame 4 , the insect-proof window frame 6 is arranged inside the bird-proof window frame 4 , and the front surface of the insect-proof window frame 6 does not protrude from the bird-proof window frame 4 after installation.

[0042] The insect-proof window frame 6 and the bird-proof window frame 4 are detachably connected: the insect-proof window frame 6 and the bird-proof window frame 4 are respectively provided with magnets, and the insect-proof window frame 6 is detachably connected to the bird-proof window frame 4 by the attraction of the magnets. The structure is simple and easy to install and disassemble.

[0043] Furthermore, magnets are provided on the four corners of the insect-proof window frame 6 and the four corners of the bird-proof window frame 4 respectively.

[0044] The bird-proof window frame 4 is connected to the inner window frame 2 in the following way: one side of the bird-proof window frame 4 is hinged to the inner window frame 2 by a hinge, and the other side is detachably connected to the inner window frame 2.

[0045] The bird-proof window frame 4 and the inner window frame 2 can be detachably connected in a manner that the bird-proof window frame 4 and the inner window frame 2 are detachably connected to each other by attraction of magnets.

[0046] In order to facilitate the removal of the insect-proof window frame 6 and the opening of the bird-proof window frame 4 , handles are provided on the bird-proof window frame 4 and the insect-proof window frame 6 .

[0047] The handle structure of the insect-proof window frame 6: The handle of the insect-proof window frame 6 is a pull plate 9 welded on one side of the insect-proof window frame 6, which has a simple structure and is easy to install. There are two pull plates 9, which are respectively located on the left and right sides of the insect-proof window frame 6.

[0048] The handle structure of the bird-proof window frame 4 is a U-shaped pull rod 10 with both ends slidably mounted inside the bird-proof window frame 4. When the handle is not in use, both ends of the U-shaped pull rod 10 are located inside the bird-proof window frame 4. When in use, the U-shaped pull rod 10 is pulled out, effectively reducing the space occupied by the U-shaped pull rod 10 when not in use and improving the appearance.

[0049] In order to prevent the U-shaped pull rod 10 from falling out, both ends of the U-shaped pull rod 10 are respectively provided with limit blocks located in the bird-proof window frame 4.

[0050] Example 2: Participation Figure 5 :

[0051] This embodiment has a substantially identical structure to the first embodiment, with the primary difference being that the bird-proof window frame 4 is connected to the inner window frame 2 by magnets disposed on each of the inner window frame 2 and the bird-proof window frame 4. The bird-proof window frame 4 is detachably connected to the inner window frame 2 by magnets. When full ventilation is required, the bird-proof window frame 4 can be removed, further increasing the ventilation area and improving ventilation.

[0052] Furthermore, magnets are provided on the four corners of the bird-proof window frame 4 and the four corners of the inner window frame 2 respectively.

[0053] Handle Structure: The handle is a U-shaped pull rod 10 with both ends slidingly mounted within the corresponding window frame. The bird-proof window frame 4 has two U-shaped pull rods 10, one on each side. The insect-proof window frame 6 has two U-shaped pull rods 10, one on each side.

[0054] The above embodiment is only one of the preferred embodiments of the present invention and is not intended to limit the scope of implementation of the present invention. Therefore, any equivalent changes made based on the shape, structure, and principle of the present invention should be included in the scope of protection of the present invention.
