In order to solve the technical problem, the utility model provides a following technical scheme:
the utility model provides a sealed board-like exhaust port, includes and discharges fume tub and closing plate, the both ends of closing plate all are provided with the pivot, the closing plate is intraductal in discharging fume through pivot movable mounting, the one end integration of pivot is provided with the rocking handle, the cover is equipped with torsion spring in the pivot, torsion spring's one end and closing plate fixed connection, the other end and the inside wall fixed connection who discharges fume the pipe, it is provided with the recess on the inside wall of pipe to discharge fume, the rigid coupling has the spring in the recess, the top fixed mounting of spring has the plastics dog.
As a preferred technical scheme of the utility model, overhead gage and lower baffle are installed respectively to the inside upper and lower side of discharge fume duct, just overhead gage and lower baffle are located the both sides of closing plate respectively.
As an optimized technical scheme of the utility model, the outer lane cover of closing plate is equipped with the round sealing washer.
As a preferred technical scheme of the utility model, the plastics dog is installed in one side of the intraductal air intake of discharging fume.
As an optimal technical scheme of the utility model, the one end of plastics dog is provided with the slope landslide, just the slope of plastics dog is installed on the tub inside wall of discharging fume.
Compared with the prior art, the utility model discloses the beneficial effect that can reach is:
the sealing plate in the smoke exhaust port of the utility model is controlled by the manual rocking handle, and the sealing plate can be manually opened by the rocking handle to exhaust smoke when a fire disaster occurs, so that the temperature of hot gas on the fire scene is reduced, and the death of victims in the fire scene caused by excessive smoke and oxygen deficiency is avoided; be provided with spring return mechanism on the closing plate and cooperate the plastics dog to be spacing fixed, when the conflagration comparatively seriously spreads in the smoke vent, because the melting temperature of plastics is 220 and supplyes 250 degrees, the plastics dog is melted by high temperature, no longer blocks the closing plate and resets, and closing in time the exhaust port is sealed to closing of closing plate self-reset, isolated air supply prevents that the conflagration from stretching from the exhaust port simultaneously.
