DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figures 1 to 4 In an embodiment of the present invention, a curtain wall smoke exhaust window that is easy to open and close includes a smoke exhaust window 1 composed of a fixed frame 101, a rectangular sealing frame 102, and a window frame 103. The rectangular sealing frame 102 is fixed to the middle of the inner side of the fixed frame 101, and the window frame 103 is distributed on the inner side of the fixed frame 101 and is in contact with the front end of the rectangular sealing frame 102. An opening and closing component 2 is provided between the fixed frame 101 and the window frame 103. The opening and closing component 2 is used to realize the lifting and opening and closing operations of the window frame 103.

[0026] The opening and closing assembly 2 includes a vertical track 201, a guide rail groove 202, a limit vertical rail groove 203, a lifting rail seat 204, a horizontal connecting plate 205, a guide column 206, a limit guide block 207, and an electric chain window opener 208;

[0027] The vertical rails 201 are symmetrically fixed on both sides of the inner wall of the fixed frame 101 and distributed at the rear end of the rectangular sealing frame 102. The guide rail groove 202 and the limit vertical rail groove 203 are opened on the side where the two vertical rails 201 are close to each other.

[0028] The limiting guide block 207 is fixed to one side of the lifting rail seat 204. The lifting rail seat 204 is distributed on one side of the vertical track 201 and is vertically slidably connected to the limiting vertical rail groove 203 through the limiting guide block 207. The horizontal connecting plate 205 is horizontally slidably connected to the inner side of the lifting rail seat 204 and extends to one end outside the lifting rail seat 204. The side surface of one end of the horizontal connecting plate 205 is in contact with the inner wall side of the window frame 103 and is fixedly connected to the window frame 103.

[0029] The guide post 206 is fixed to the side surface of the other end of the horizontal connecting plate 205 and passes through the outside of one side of the lifting rail seat 204. The guide post 206 is vertically slidably connected to the guide rail groove 202;

[0030] The electric chain window opener 208 is fixedly mounted on the top of the rear end of the fixed frame 101, and the output end of the electric chain window opener 208 is fixedly connected to the top of the lifting rail seat 204;

[0031] The window frame 103 is raised and lowered by the telescopic operation of the electric chain window opener 208, and the position-limiting guide block 207 cooperates with the position-limiting vertical rail groove 203 and the guide column 206 cooperates with the guide rail groove 202 to provide guidance for the raising and lowering of the window frame 103;

[0032] The side end of the guide column 206 is spherical in structure, and the guide rail groove 202 consists of a vertical groove and an inclined groove, and the inclined groove is located at the top of the vertical groove;

[0033] The inner side of the lifting rail seat 204 is formed with a sideways "convex" rail groove for the horizontal connecting plate 205 and the guide column 206 to slide horizontally;

[0034] The inner bottom of the fixing frame 101 near the front end and the lower surface of the window frame 103 are inclined, and the inclination angle of the inclined structure matches the inclination angle of the inclined groove.

[0035] In this embodiment, it should be additionally explained that a glass window is installed on the inner side of the window frame 103. When the window frame 103 blocks the fixed frame 101, the chain of the electric chain window opener 208 is in a retracted state. At this time, the guide column 206 is located at the top of the inclined groove, and the window frame 103 is tightly fitted with the end face of the rectangular sealing frame 102. The end face of the rectangular sealing frame 102 is provided with a corresponding sealing member to ensure the sealing of the blocked state.

[0036] When the curtain wall smoke exhaust window needs to be opened, the electric chain window opener 208 is started, and the chain of the electric chain window opener 208 extends outward and pushes the lifting rail seat 204, the limiting guide block 207, the horizontal connecting plate 205, the guide column 206 and the window frame 103 to move downward as a whole. During this process, the guide column 206 moves along the inclined groove track to the inside of the vertical groove, so that the horizontal connecting plate 205 and the window frame 103 move downward as a whole and move horizontally, so that the window frame 103 moves to the outside of the front end of the fixed frame 101, that is, at this time the window frame 103 and the fixed frame 101 are displaced in the horizontal direction. During the process of the guide column 206 moving downward along the vertical groove, the window frame 103 can continue to move downward without colliding with the fixed frame 101;

[0037] By moving the window frame 103 downward, the blockage of the fixed frame 101 can be released, thereby achieving the effect of opening the curtain wall smoke exhaust window. Compared with the traditional smoke exhaust window with a 70-degree opening angle structure, the front of the fixed frame 101 is unobstructed, which can better carry out fire rescue operations such as drones, fire hoses, and fire ladders.

[0038] Please refer to Figures 1 to 4 , a buffer rubber block 3 is fixedly installed on the bottom of the inner wall of the fixed frame 101 near the side of the vertical track 201, and the top horizontal height of the buffer rubber block 3 is higher than the bottom horizontal height of the inner wall of the rectangular sealing frame 102;

[0039] Two electric chain window openers 208 are symmetrically fixedly connected to the top of the fixed frame 101 . The length of the stainless steel chain of the electric chain window openers 208 is greater than the height of the inner wall of the fixed frame 101 .

[0040] In this embodiment, the two electric chain window openers 208 can provide sufficient pulling force for the lifting operation of the window frame 103, and at the same time make the lifting operation of the window frame 103 more stable. The buffer rubber block 3 can provide buffering and limiting for the downward movement of the window frame 103, thereby preventing the lifting rail seat 204 from contacting and colliding with the rectangular sealing frame 102.

[0041] It should also be noted that the electric chain window opener 208 adopts a conventional chain window opener on the market, which has a mature technical principle and has been widely used in the field of smoke exhaust windows. Therefore, the working principle of the chain window opener will not be described here in detail.

[0042] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
