[0034] like Figure 1-12As shown, the locking mechanism is fixedly connected to the ventilating window 3. The locking mechanism includes a fitting plate 6 movably installed in the fitting groove 42, and the end of the fitting plate 6 facing the room is fixedly connected to the rear plate frame 32 by bolts. The ventilating window 3 is installed in place so that the outer side of the fitting plate 6 is flush with the rear plate frame 32, and the end surface of the fitting plate 6 facing the room is provided with a rectangular groove 61 from the room to the outside, and a pressing plate 5 is movably inserted in the rectangular groove 61, and a clamping mechanism is provided on the lower side of the pressing plate 5, and the clamping mechanism is used to abut and cooperate with the pressing plate 5, so that the clamping mechanism is clamped and fixed between the rectangular groove 61 and the side wall of the fitting groove 42.

[0035] like Figure 2-4 , Figure 8-12 As shown, a locking groove 43 is provided on the side wall of the engaging groove 42, and a notch for communicating with the locking groove 43 is provided on the side wall of the rectangular groove 61. The locking mechanism includes a locking block 1 and a second elastic mechanism. The locking block 1 is located at the notch in the rectangular groove 61 and can slide out of the notch. One side of the locking block 1 is installed on the inner wall of the engaging plate 6 through the second elastic mechanism. When the locking groove 43 is connected with the notch, the pressing plate 5 squeezes the locking block 1 and resists against the locking block 1, so that the locking block 1 passes through the notch and is locked into the locking groove 43, thereby locking and fixing the engaging plate 6 and the door body 4.

[0036] In the above embodiment, the side wall of the rectangular groove 61 is recessed inward to provide a connecting groove 10, which is located at the notch of the rectangular groove 61 and is connected to the notch. The locking block 1 is located in the connecting groove 10 and can slide outward of the notch in the vertical direction under the action of the second elastic mechanism. When the engaging plate 6 is fully inserted into the engaging groove 42, the notch and the engaging groove 43 are just connected. At this time, the pressing plate 5 can be pressed inward, and the pressing plate 5 squeezes the locking block 1 and presses against the locking block 1, so that the part of the locking block 1 located at the bottom is embedded in the locking groove 43, and the part of the locking block 1 located at the top is still located in the rectangular groove 61, and the engaging plate 6 and the door body 4 are limited in the horizontal direction, so that the engaging plate 6 and the door body 4 are connected and fixed, and the installation of the ventilation window 3 is completed, and the stability of the connection between the ventilation window 3 and the door body 4 is high.

[0037] like Figure 9-10 As shown, a moving groove 51 for engaging with the locking block 1 is formed through one side of the pressing plate 5 . When the locking block 1 is locked in the locking groove 43 , the moving groove 51 is located outside the locking block 1 .

[0038] In this embodiment, a movable groove 51 is provided to facilitate the disassembly of the ventilation window 3. When disassembly is required, the pressing plate 5 is pressed inward until the movable groove 51 is aligned with the notch of the rectangular groove 61, and the positioning block 1 leaves the positioning groove 43 and is embedded in the movable groove 51 under the action of the second elastic mechanism. The restriction of the positioning block 1 on the interlocking plate 6 and the door body 4 is released, and the ventilation window 3 can be disassembled, which is easy, convenient and quick.

[0039] like Figure 10-12 As shown, the second elastic mechanism includes a second limiting column 8 fixedly mounted on the inner wall of the interlocking plate 6 in the vertical direction, and a tension spring 9 is movably sleeved on the surface of the second limiting column 8.

The outer side and the inner side of the positioning block 1 connected to the tension spring 9 are respectively provided with extrusion inclined surfaces for extrusion with the pressing plate 5.

[0040] In the above embodiment, the tension spring 9 is located in the connecting groove 10 to avoid interference with the pressing plate 5. When no external force is applied, the blocking block 1 is located in the rectangular groove 61 under the action of the tension spring 9 and does not extend out of the notch. The extrusion slope is convenient for the pressing plate 5 to control the position of the moving blocking block 1 through the extrusion slope under the elastic action of the tension spring 9, so that the blocking block 1 is squeezed into the blocking groove 43 to avoid the blocking block 1 being stuck in the rectangular groove 61. When the pressing plate 5 squeezes the blocking block 1 into the blocking groove 4 3, the tension spring 9 is in a stretched state. During subsequent disassembly, the pressing plate 5 continues to be pressed inwards until the moving groove 51 is aligned with the locking block 1. Under the tension of the tension spring 9, the locking block 1 moves into the moving groove 51. By arranging a second limiting column 8 inside the tension spring 9, the moving distance of the locking block 1 can be limited. The second limiting column 8 can prevent the locking block 1 from being too close to the interlocking plate 6 under the control of the tension spring 9, which is not conducive to the pressing plate 5 pushing the locking block 1 into the locking groove 43 by squeezing the inclined surface.

[0041] like Figure 10-11 As shown, a first elastic mechanism is arranged between the end surface of the pressing plate 5 facing the outdoors and the inner wall of the rectangular groove 61. The first elastic mechanism is used to limit the depth of the pressing plate 5 in the rectangular groove 61. The first elastic mechanism includes a first limiting column 2 fixedly installed on the inner wall of the rectangular groove 61 and a return spring 7 mounted on the surface of the first limiting column 2. One end of the return spring 7 is fixedly connected to the end surface of the pressing plate 5 facing the outdoors.

[0042] In this embodiment, the other end of the return spring 7 is used to abut against the inner wall of the rectangular groove 61. After the locking block 1 is inserted into the locking groove 43 and installed in place, the return spring 7 can correct the flatness of the pressing plate 5 so that the outer side of the pressing plate 5 is flush with the outer side of the engaging plate 6. By setting a first limiting column 2 inside the return spring 7, the moving distance of the pressing plate 5 can be limited, which is convenient for the user to limit the position through the first limiting column 2. When the bottom is pressed, the locking block 1 can be directly connected to the position of the moving groove 51.

[0043] like Figure 4-6As shown, the baffle plate 11 can be opened and closed in the rear frame 32. In fact, the baffle plate can be snap-fitted in the rear frame 32. In this embodiment, one side of the baffle is hinged to the rear plate frame 32 by a hinge, and a limiting mechanism is arranged on the other side of the baffle, the limiting mechanism includes a switch 12, and a first slide groove recessed inwardly is arranged on the surface of the side of the shielding plate 11 close to the room in the horizontal direction, the inner side of the switch 12 is slidably embedded in the first slide groove, and the outer side of the switch 12 extends out of the first slide groove, and the part of the switch 12 located in the first slide groove is integrally connected with a locking plate 14 that penetrates the side wall of the first slide groove and extends out of the shielding plate 11, and a limiting groove matching the locking plate 14 is opened on the rear plate frame 32 of the ventilation window 3, and a third limiting column 16 is arranged on the right side of the switch 12, and a spring is sleeved on the surface of the third limiting column 16, and a fixing plate 15 is integrally formed on the surface of the side of the shielding plate 11 close to the room, and the fixing plate 15 is spaced apart from the outer side of the switch 12, one end of the spring is fixedly connected to the outer side wall of the switch 12, and the other end of the spring is fixedly connected to the fixing plate 15, and a protective shell 13 is also arranged on the switch 12 and the fixing plate 15 to protect the limiting mechanism. By pressing the switch 12, the locking plate 14 can be driven to slide in the first slide groove, so that the locking plate 14 can be extended or retracted into the shielding plate 11. The locking plate 14 cooperates with the limit groove to realize the opening and closing of the shielding plate 11, and the opening and closing of the ventilation window 3 and the size of the opening and closing can be adjusted, which has a certain protective effect on indoor privacy.

[0044] like Figure 1-3 As shown, a limit plate 45 is slidably mounted on the door body 4 , and the limit plate 45 is used to block the notch of the fitting groove 42 .

[0045] In this embodiment, a second slide groove 44 is arranged in the horizontal direction on the indoor side of the door body 4, and the limiting plate 45 is slidably installed in the second slide groove 44. When the ventilation window 3 is installed in place, the limiting plate 45 can be slid to cover the notch of the interlocking groove 42 to prevent the pressing plate 5 from shifting.

[0046] During on-site operation, if the user needs to replace or disassemble the ventilation window 3, he only needs to use tools or both hands to squeeze the pressing plates 5 on both sides of the rear plate frame 32 inward at the same time, and the reset spring 7 will contact the pressing plates 5 with the first limit column 2 under the elastic action. At this time, the movable groove 51, the notch, and the locking groove 43 are connected, and the locking block 1 moves to the inside of the movable groove 51 under the tension of the tension spring 9 and is embedded in the movable groove 51. Since there is no locking block 1 stuck in the locking groove 43, the interlocking plate 6 and the ventilation window 3 can be directly moved into the door body 4 at this time to complete the disassembly of the ventilation window 3. The ventilation window 3 and the screen window can be directly maintained, replaced or cleaned later. Only one person can easily disassemble the ventilation window 3; if installation is required Ventilation window 3, snap the screen into the ventilation window 3, place the ventilation window 3 in the installation groove 41, and at the same time embed the embedding plate 6 into the embedding groove 42. When the embedding plate 6 is embedded in place, the notch of the rectangular groove 61 is aligned with the locking groove 43, and then the pressing plate 5 is inserted inward from the outside of the rectangular groove 61. The pressing plate 5 squeezes the extrusion slope above the locking block 1, so that the locking block 1 is locked into the locking groove 43, and the embedding plate 6 and the door body 4 are locked and fixed. At this time, continue to press the pressing plate 5 down until the reset spring 7 is mounted on the first limiting column 2 and against the bottom wall of the rectangular groove 61. The reset spring 7 corrects the outer side of the pressing plate 5 so that the outer side of the pressing plate 5 is flush with the embedding plate 6, and the installation of the ventilation window 3 is completed.
