[0030] The technical solution of the present utility model will be described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.

[0031] As described in the background art of the present application, the smoke exhaust port is in a normally closed state, and the door panel of the smoke exhaust port is fixed to the housing through a locking mechanism, and the locking mechanism is connected to a remote control actuator. When a fire occurs, the door panel can be opened through the remote control actuator, the smoke exhaust port is opened, and the smoke and fumes in the room are discharged.

[0032] The inventors of the present application found that in the currently commonly used smoke exhaust port structure, the sealing performance is poor when closed, the air leakage is large, and the door panel is prone to jamming when opened.

[0033] To solve the above problems, the inventors of the present application proposed the technical solution of the present application, and the specific embodiments are as follows:

[0034] Figure 1 It is the front view schematic diagram of the plate-type smoke exhaust port structure in the embodiment of the present utility model, Figure 2 It is the side view schematic diagram of the plate-type smoke exhaust port structure in the embodiment of the present utility model, Figure 3 It is the schematic diagram of the open state of the plate-type smoke exhaust port structure in the embodiment of the present utility model, Figure 4 It is in the embodiment of the present utility model Figure 3 The enlarged view of the A position in.

[0035] As Figures 1 to 4 shown, the plate-type smoke exhaust port structure of this embodiment includes: a rectangular frame 1, a door panel 2, a tension spring 3, a gas spring 4, and a remote control actuator 5.

[0036] A limiting stop strip 11 is provided on the inner wall of the rectangular frame 1.

[0037] The door panel 2 is a rectangular plate, and the two opposite sides of the door panel 2 are rotatably arranged on the rectangular frame 1 through a rotating shaft 6, and the door panel 2 is located inside the frame of the rectangular frame 1.

[0038] There are two tension springs 3. One end of each of the two tension springs 3 is arranged on the inner wall of the rectangular frame 1, and the other ends of the two tension springs 3 are respectively arranged at two opposite side walls of the door panel 2. One end of the gas spring 4 is arranged on the rectangular frame 1, and the other end of the gas spring 4 is arranged on the door panel 2.

[0039] The rectangular frame 1 is generally installed on the indoor ceiling or wall of a windowless room and is connected to the outside atmosphere through a smoke exhaust duct.

[0040] The door panel 2 is rotatably arranged inside the rectangular frame 1 through a rotating shaft 6, and the door panel 2 can be fixed on the rectangular frame 1 through a locking mechanism that cooperates with each other on the door panel 2 and the rectangular frame 1. When the door panel 2 is locked and fixed, it abuts against the limit stop 11 of the rectangular frame 1, and the passage of the rectangular frame 1 is closed. At this time, the smoke exhaust opening (rectangular frame) is in a closed state. When the smoke exhaust opening is closed, the tension spring 3 tightens the door panel 2, so that the door panel 2 fits tightly with the limit stop 11 of the rectangular frame 1, the smoke exhaust opening is closed more tightly, and the air leakage of the smoke exhaust opening is reduced.

[0041] The remote control actuator 5 is connected to the locking mechanism of the smoke exhaust opening through a steel wire rope. When the remote control actuator 5 is triggered, it pulls the locking mechanism, so that the door panel 2 is released from the rectangular frame 1. At this time, the door panel 2 rotates around the rotating shaft 6 under the action of the gas spring 4, so that the smoke exhaust opening is opened. After the door panel 2 rotates 90° and is fully opened, the gas spring 4 forms a supporting and fixing effect on the door panel 2, so that the door panel 2 remains stable and the smoke exhaust opening remains in the maximum ventilation volume state. Of course, when pulling the steel wire rope, the smoke exhaust opening (door panel) can be manually opened, and the smoke exhaust opening can be manually reset and closed.

[0042] It is not difficult to find from the above content that the structure of the plate-type smoke exhaust opening in this embodiment, by setting a rectangular frame, a door panel, a tension spring, a gas spring and a remote control actuator, the rectangular frame is provided with a limit stop, the door panel is arranged on the rectangular frame, and both ends of the tension spring and the gas spring are respectively arranged on the rectangular frame and the door panel. When the door panel is fixed, it abuts against the limit stop, the tension spring is used to tighten the door panel, and the remote control actuator is used to trigger the locking mechanism to release the door panel. The gas spring makes the released door panel rotate and forms a support for the door panel after the door panel rotates 90°. In the structure of the plate-type smoke exhaust opening in this embodiment, the door panel fits on the limit stop of the rectangular frame when closed, is fixed through the locking mechanism, and is tightened by the tension spring, so that the smoke exhaust opening is more sealed and the air leakage is reduced; when the door panel needs to be rotated and opened, the remote control actuator unlocks the locking mechanism, and the door panel rotates and opens under the action of the gas spring. The opening action of the door panel is more reliable, and after the door panel rotates 90° and is fully opened, the gas spring forms a supporting and fixing effect on the door panel, so that the smoke exhaust opening remains in the maximum ventilation volume state.

[0043] Optionally, in the plate-type smoke exhaust opening structure of this embodiment, a decorative outer frame 12 is provided on one side of the opening of the rectangular frame body 1, and the decorative outer frame 12 extends outward to the periphery of the rectangular frame body 1.
