The outer surface of the displacement block 8 is slidably connected to the inner wall of the vertical groove 6. The bottom of the displacement block 8 is fixedly connected with a moving key 9, and the top of the displacement block 8 is fixedly connected with a displacement arm 10.

[0024] The above solution is adopted: by setting the displacement block 8, when the moving key 9 is moved backward, it can drive the displacement block 8 to slide backward along the vertical groove 6, so that the sliding displacement block 8 can synchronously drive the movement of the displacement arm 10.

[0025] refer to Figure 4 The displacement arm 10 is arranged on the inner wall of the connecting groove 4, the bottom of the displacement arm 10 is fixedly connected to the top of the displacement block 8, the upper and lower ends of the displacement arm 10 close to the opening 601 are respectively fixedly connected with the displacement rod 11, and the two displacement rods 11 are respectively provided with a rotating arm 12 on the side away from each other.

[0026] The above solution is adopted: by setting the displacement arm 10, the displacement arm 10 can be driven by the displacement block 8 to move backward in the connecting groove 4, and at the same time drive the movement of the two displacement rods 11, so that the two moving displacement rods 11 can respectively drive the two rotating arms 12 to rotate.

[0027] refer to Figure 4 The two rotating arms 12 are respectively arranged on the inner wall of the connecting groove 4 at the upper and lower ends. The ends of the two rotating arms 12 that are away from each other are respectively connected to the inner wall of the connecting groove 4 through rotating shafts. The surfaces of the ends of the two rotating arms 12 that are close to each other are respectively fitted with the outer surfaces of the two displacement rods 11, and the ends of the two rotating arms 12 that are away from each other are respectively fixedly connected with a pushing arm 13.

[0028] The above solution is adopted: by setting the rotating arms 12, the two rotating arms 12 can be respectively squeezed by the displacement rod 11 and rotate relative to each other in the connecting groove 4, so that the two rotating arms 12 can respectively drive the synchronous rotation of the two pushing arms 13 during the rotation process.

[0029] refer to Figure 4 The rear ends of the two pushing arms 13 are respectively fixedly connected to the front faces of the two rotating arms 12 away from each other. The front ends of the two pushing arms 13 are respectively provided with pushing grooves 14 on the sides close to each other. The inner walls of the two pushing grooves 14 are respectively sleeved with driven rods 15. The two driven rods 15 are respectively fixedly connected with driven arms 16 on the sides close to the opening 601.

[0030] The above solution is adopted: by setting the pushing arms 13, the two pushing arms 13 can push the two passive rods 15 to move closer through the pushing grooves 14 when rotating, so that the two passive rods 15 can respectively drive the two passive arms 16 to move closer.

[0031] refer to Figure 4 The middle of the rear ends of the two passive arms 16 are respectively slidably connected to the outer surface of the vertical rod 401, and the side of the two passive arms 16 close to each other is fixedly connected with a resistance spring 17, and the resistance spring 17 is sleeved on the outer surface of the vertical rod 401, and the side of the two passive arms 16 away from the pushing arm 13 is respectively fixedly connected with a resistance block 18.

[0032] The above solution is adopted: by setting the passive arms 16, the two passive arms 16 can be driven by the passive rod 15 respectively, slide close to each other on the surface of the vertical rod 401, and squeeze the resistance spring 17 for compression. The two passive arms 16 slide and then drive the two resistance blocks 18 to move close to each other.

[0033] refer to Figure 3 and Figure 4 The two resistance blocks 18 are respectively fixedly connected to the sides of the front ends of the two driven arms 16 that are away from each other, and the ends of the two resistance blocks 18 that are away from each other are respectively inserted into the inner walls of the fitting grooves 701.

[0034] The above solution is adopted: by providing the resistance blocks 18 , the two resistance blocks 18 can be separated from the fitting grooves 701 respectively when they move closer to each other, thereby releasing the fixation of the fitting block 7 , thereby releasing the fixation of the mounting bar 2 .

[0035] The working principle of this utility model:

[0036] When in use, the fitting block 7 is inserted into the opening 601, and the fitting block 7 moves and squeezes the surfaces of the two resistance blocks 18 at the same time, driving the two passive arms 16 to slide close to each other on the surface of the vertical rod 401 and squeezing the compression of the resistance spring 17. When the fitting block 7 is fully inserted into the opening 601, the resistance spring 17 pushes the two passive arms 16 to slide, driving the two resistance blocks 18 to move and insert into the fitting groove 701 to fix the fitting block 7. Repeat this process and insert another fitting block 7 into the opening 601 and fix it, so that the two The two mounting strips 2 are fixed on the left and right sides of the window frame 1 respectively. Then, the window frame 1 together with the smoke exhaust window 101 is moved to the reserved position on the roof, and the two mounting strips 2 are bent to fit the surface of the installation position. The two mounting strips 2 are preliminarily fixed through the mounting holes 201 with fixing bolts, thereby preliminarily fixing the window frame 1. Then, the four sealing plates 3 are moved to the bottom of the window frame 1 and respectively inserted into the bayonet 102 through the clamping strips 301 to lay the four sealing plates 3 on the top of the window frame 1 that fits the reserved position. Finally, apply sealant to the fitted position for sealing and fixing, and then apply sealant to the four sealing plates 3 and fit them on the roof to complete the installation of the window frame 1 and the smoke exhaust window 101. At the same time, the sealing plates 3 laid at the connection can play a rainproof effect. When it is necessary to use different installation strips 2, when the moving key 9 is moved backward, the displacement block 8 is driven to slide along the vertical groove 6, and the displacement arm 10 is synchronously driven to move in the connecting groove 4, and at the same time, the two displacement rods 11 are driven to move backward. The two displacement rods 11 move backward and squeeze the surface of the two rotating arms 12 at the same time. When the two pushing arms 13 rotate, they squeeze the two driven rods 15 through the pushing groove 14 to drive the two driven arms 16 to slide closer on the vertical rod 401. When the resistance spring 17 is compressed, the two resistance blocks 18 are driven to move closer, so that the two resistance blocks 18 are disengaged from the fitting groove 701 to release the fixation of the fitting block 7, thereby releasing the fixation of the mounting bar 2 and allowing it to be replaced to adapt to different installation environments.

[0037] To sum up: the wind and rainproof sealing structure of the fire skylight, through the cooperation of the window frame 1, the installation strip 2, the sealing plate 3, the connecting groove 4 and the solid auxiliary structure 5, solves the problem that during the installation of the fire skylight, if there is an error in the distance between the window frame and the wall, it may cause the sealing strip to be installed improperly, resulting in a decrease in the sealing of the skylight, causing the skylight to leak in rainy weather, causing moisture inside the building.
