Aluminum alloy insect-proof nets 3 are arranged between adjacent window blade bodies 2. Switch assemblies 5 and self-locking mechanisms 6 are respectively arranged in the cavities on both sides of the aluminum alloy frame 1, and the switch assembly 5 and the self-locking mechanism 6 connect the plurality of window blade bodies 2 so that their movement states are consistent. A pulling assembly 4 is provided between the top and bottom of the aluminum alloy frame 1, and the pulling assembly 4 connects the plurality of aluminum alloy insect-proof nets 3 in series so that their movement states are consistent. A bottom waterproof mechanism 7 is provided at the bottom of the inner frame of the aluminum alloy frame 1.

[0032] The window leaf body 2 includes an aluminum alloy window leaf 21 that fits in the window leaf mounting hole. Support shafts 22 are symmetrically provided on both sides of the aluminum alloy window leaf 21, and the support shafts 22 and the window leaf mounting hole form a matching mechanism. An insect-proof net card slot A23 is welded to one end of the upper surface of the aluminum alloy window leaf 21. The insect-proof net card slot A23 is provided with multiple makeshift slots, and a buckle 24 is provided at the notch of the makeshift slot. Two elongated holes are symmetrically provided at the other end of the aluminum alloy window leaf 21, and two fixing rings A25 are symmetrically provided on one side of the elongated hole.

[0033] The pulling assembly 4 includes a plurality of pulleys 41 fixed to the cavities at the upper and lower ends of the aluminum alloy frame 1 by bolts, and a rope 42 is installed between the upper and lower pulleys 41, and the rope 42 forms a closed annular rope loop, one side of the rope loop passes through the elongated holes provided in the plurality of aluminum alloy window blades 21, and the other side of the rope loop is fixed to the fixing rings A25 provided in the plurality of aluminum alloy window blades 21, and a movable plate body 43 is fixedly installed on the outer wall of the rope 42 below the elongated hole, and the movable plate body 43 includes a movable plate 431 fixed on the rope 42, and a fixing ring B433 is symmetrically provided at the center position of the movable plate 431, and the fixing ring B433 and the rope 42 form a matching mechanism, a clearance hole is provided on one side of the fixing ring B433, and the rope 42 fixed to one side of the fixing ring A25 passes through the clearance hole, and an insect-proof net card slot B432 is integrally formed at one end of the movable plate 431, and the insect-proof net card slot B432 and the insect-proof net mounting shaft 31 form a matching mechanism;

[0034] The aluminum alloy insect-proof net 3 is composed of an insect-proof net mounting shaft 31, an elastic rope 33 and a mesh 32. A plurality of meshes 32 are tied in series by the elastic rope 33 to form an elastic net. The two ends of the elastic net are tied to the insect-proof net mounting shaft 31 by the elastic rope 33, and the insect-proof net mounting shafts 31 at both ends are respectively matched with the insect-proof net card slot A23 and the movable plate body 43. The elastic rope 33 will expand and contract with the change of tension, and the rope 42 will not expand and contract during the movement. The plurality of aluminum alloy window blades 21 are rotated and matched in the inner frame of the aluminum alloy frame 1, and The spacing between adjacent aluminum alloy window blades 21 is the same. A long hole is opened at one end of the aluminum alloy window blade 21. One side of the rope 42 passes through the long hole, and the other side is fixed to the aluminum alloy window blade 21 through a fixing ring A25. The opening and closing of the aluminum alloy window blade 21 drives the rope 42 to reciprocate. A plurality of movable plates 431 are fixed to the rope 42 through a fixing ring B433. When the blinds are opened, the aluminum alloy window blade 21 moves downward near one end of the rope 42, thereby pulling the rope 42, and the movable plate 431 on the fixed rope 42 is pulled by the rope 42. When the shutter is closed, the end of the aluminum alloy window blade 21 close to the rope 42 moves upward, thereby resetting the movable plate 431. The two ends of the aluminum alloy insect-proof net 3 are respectively fitted in the insect-proof net card slot A23 and the insect-proof net card slot B432. The elastic rope 33 is fitted in the card slot opened by the insect-proof net card slot A23 and the insect-proof net card slot B432. After the aluminum alloy insect-proof net 3 is installed, the buckle 24 provided on the insect-proof net card slot A23 is buckled to prevent the aluminum alloy insect-proof net 3 from falling off under the action of gravity. When the shutter is opened, the movable plate 431 moves upward to stretch the aluminum alloy insect-proof net 3. The alloy insect-proof net 3 is blocked in the gap between the shutter blades. At this time, the aluminum alloy insect-proof net 3 is stretched, and the gap between the meshes prevents mosquitoes from entering the room while ensuring ventilation. When the shutters are closed, the movable plate 431 moves downward. At this time, the aluminum alloy insect-proof net 3 contracts. Under the action of gravity, one end of the aluminum alloy insect-proof net 3 close to the front end of the aluminum alloy window blade 21 is stacked between two adjacent aluminum alloy window blades 21, and at this time the spacing between the meshes of the aluminum alloy insect-proof net 3 becomes smaller, blocking it between the two aluminum alloy window blades 21, and can prevent rainwater from entering the house when it rains heavily.

[0035] The bottom waterproof mechanism 7 includes a baffle 72 welded to the bottom of the inner frame of the aluminum alloy frame 1, and a bottom insect-proof net card slot 71 is welded in front of the baffle 72. The top and bottom of the inner frame of the aluminum alloy frame 1 are both provided with aluminum alloy insect-proof nets 3. One end of the bottom aluminum alloy insect-proof net 3 fits in the bottom insect-proof net card slot 71. On rainy days, rainwater flowing down from the blinds flows to the bottom and is blocked by the baffle 72 to prevent it from entering the house. At the same time, the rainwater flows out from the drainage groove opened in front of the baffle.

[0036] The switch assembly 5 includes a plurality of rotating plates A51 fixedly connected to the support shaft 22 by bolts, the ends of the rotating plates A51 are provided with rollers, and the rollers of the plurality of rotating plates A51 are rotatably engaged with the connecting plate A52, and the middle area of ​​the connecting plate A52 is provided with two rollers A53, and the outer wall of the roller A53 is slidably engaged with a sliding plate A55, and one end of the sliding plate A55 is welded to a push rod 56, and one end of the push rod 56 passes through an end surface of the aluminum alloy frame 1, and a limit block A54 is provided at one side of the sliding plate A55, and the limit block A54 is fixed to the inner wall of the aluminum alloy frame 1 by bolts;

[0037] The self-locking mechanism 6 includes a plurality of rotating plates B61 fixedly connected to the supporting shaft 22 by bolts, a roller is provided at the end of the rotating plate B61, and the rollers of the plurality of rotating plates B61 are rotatably fitted on the connecting plate B62, two rollers B63 are provided in the middle area of ​​the connecting plate B62, a sliding plate B64 is slidably fitted on the outer wall of the roller B63, a limiting block B66 is provided on one side of the sliding plate B64, and the limiting block B66 is fixed to the inner wall of the aluminum alloy frame 1 by bolts, a circular hole is provided at one end of the sliding plate B64, and a fixed shaft 65 is embedded in the circular hole, a limiting component 67 is provided on one side of the sliding plate B64, and The limit assembly 67 and the fixed shaft 65 are a matching mechanism. The limit assembly 67 includes two support columns 673 fixed by bolts to the inner wall of the aluminum alloy frame 1 and one side of the sliding plate B64. A push switch 672 is slidably matched on the outer wall of the support column 673, and one end of the push switch 672 passes through one end surface of the aluminum alloy frame 1. A limit tooth plate 671 is fixedly installed on one end surface of the push switch 672 by bolts, and the limit tooth plate 671 and the fixed shaft 65 are a matching mechanism. A reset spring 674 is provided between one end of the push switch 672 and the inner wall of the aluminum alloy frame 1. Multiple aluminum alloy window blades 21 The rotation is matched with the inner frame side wall of the aluminum alloy frame 1. The two ends of the aluminum alloy window blade 21 are connected into a whole through the rotating plate A51, the rotating plate B61, the connecting plate A52 and the connecting plate B62, so that the movement state of multiple aluminum alloy window blades 21 is the same, thereby dispersing the tension and torsion of the aluminum alloy window blade 21, making the overall structure more stable. By pushing 56, the sliding plate A55 moves, and the sliding plate A55 moves up and down between the limit block A and the inner wall of the aluminum alloy frame 1. The connecting plate A52 is driven by the roller A53 to move, thereby driving the aluminum alloy window blade 21 to rotate. At this time, the rotating plate B61, the connecting plate B62, and the roller B63 moves synchronously, thereby driving the sliding plate B64 to move up and down between the limit block B66 and the inner wall of the aluminum alloy frame 1, and a fixed shaft 65 is embedded in one end of the sliding plate B64, and the fixed shaft 65 cooperates with the limit tooth plate 671. The limit tooth plate 671 always cooperates with the fixed shaft 65 under the action of the reset spring 674. Under the action of gravity, the shutter tends to flip downward, so the fixed shaft 65 tends to move upward. The shutter is locked by locking the fixed shaft 65 through the limit tooth plate 671. When the shutter needs to be closed, press the push switch 672 to disengage the limit tooth plate 671 from the fixed shaft 65, thereby closing the shutter.

[0038] Working principle:

[0039] When the shutter is closed, the end of the aluminum alloy window blade 21 close to the rope 42 moves upward, and the aluminum alloy window blade 21 pulls the rope 42 through the fixed ring A, and under the action of the pulley 41, the rope 42 on one side of the long hole moves upward, thereby driving the movable plate 431 fixed on the outer wall of the rope 42 below the long hole to move upward. When the shutter is closed, the end of the aluminum alloy window blade 21 close to the rope 42 moves upward, and the aluminum alloy window blade 21 pulls the rope 42 through the fixed ring A, and under the action of the pulley 41, the movable plate 431 fixed on the rope 42 moves downward, thereby resetting the movable plate 431.

[0040] Insect prevention: The aluminum alloy insect-proof net 3 is made of multiple mesh sheets 32 bound together, with both ends mounted on the aluminum alloy window blades 21 and the movable plate body 43. When the blinds are flipped open, the aluminum alloy window blades 21 and the movable plate body 43 move relative to each other, stretching the aluminum alloy insect-proof net 3 so that it is blocked in the gaps between the aluminum alloy window blades 21, preventing mosquitoes from entering while also providing ventilation.

[0041] Rain protection: When the rain is heavy, the shutters are in a closed state, and the aluminum alloy insect-proof net 3 is retracted and stacked above the aluminum alloy window blades 21, making the gaps between the blades smaller, preventing rain from bouncing into the house, and the rainwater flowing down the shutters is blocked by the bottom barrier strip 72 and discharged through the drainage trough.
