[0028] like Figures 1-8 As shown, this invention provides a smoke exhaust window for a curtain wall, comprising a housing 1, which is frame-shaped and has a frame-shaped partition 2 fixedly installed inside. A smoke exhaust window body 3 is rotatably mounted inside the housing 1 via a first mounting shaft 4. The first mounting shaft 4 is located at one end of the smoke exhaust window body 3, and when the smoke exhaust window body 3 is rotated to a vertical position, it is in complete contact with the partition 2. A telescopic member 6 is provided inside the housing 1 to drive the smoke exhaust window body 3 to rotate. The telescopic member 6 is fixedly installed inside the housing 1 and is perpendicular to the first mounting shaft 4. A rack 7 is fixedly installed at the output end of the telescopic member 6, and the rack 7 meshes with a gear 5 fixedly installed on the first mounting shaft 4. The gear 5 is coaxially arranged with the first mounting shaft 4. An L-shaped baffle 8 is fixedly installed inside the housing 1, and the telescopic member 6 is located inside the baffle 8. Inside the housing 1, a guide plate 20 is rotatably mounted via a second mounting shaft 21. When the second mounting shaft 21 is located at one end of the guide plate 20 and the guide plate 20 is in a vertical state, the guide plate 20 is in complete contact with the partition 2. The guide plate 20 and the smoke exhaust window body 3 are located on both sides of the partition 2, and the first mounting shaft 4 and the second mounting shaft 21 are located at both ends of the housing 1. The first mounting shaft 4 and the second mounting shaft 21 are rotatably connected. A first groove 9 is provided on both sides of the housing 1. Both ends of the first mounting shaft 4 and the second mounting shaft 21 extend into the first groove 9. A first synchronous wheel 10 is fixedly mounted on both ends of the first mounting shaft 4, and a second synchronous wheel 22 is fixedly mounted on both ends of the second mounting shaft 21. The first synchronous wheel 10 and the second synchronous wheel 22 on the same side are rotatably connected to a synchronous belt 11.

[0030] When the smoke exhaust window body 3 is opened, the first mounting shaft 4 rotates, the first mounting shaft 4 drives the second mounting shaft 21 to synchronously rotate through the first synchronous wheel 10, the second synchronous wheel 22 and the synchronous belt 11, so that the guide plate 20 is synchronously opened with the smoke exhaust window body 3. The mass distribution of the guide plate 20 is the same as that of the smoke exhaust window body 3, so that the rotating torque of the guide plate 20 on the second mounting shaft 21 is the same as the rotating torque of the smoke exhaust window body 3 on the first mounting shaft 4, so that the torque balance of the smoke exhaust window body 3 after being opened is realized, so that the first mounting shaft 4 and the second mounting shaft 21 can be driven to rotate through very small force and the subsequent stability of the smoke exhaust window body 3 is realized, the wear of the driving components is reduced, and the service life of the equipment is improved. After the smoke exhaust window body 3 is opened, the guide plate 20 is in an inclined state, the smoke moving upward can move along the guide plate 20 after contacting the guide plate 20, so that more smoke is discharged outward, and the smoke exhaust effect is further improved. When not in use, the rack 7 moves reversely to make the smoke exhaust window body 3 and the guide plate 20 be closed and contacted with the partition plate 2.

[0031] In one example of the embodiment, the telescopic piece 6 is an electric telescopic rod, and of course can be other components capable of actively changing length such as a hydraulic cylinder.
