Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-4, the present invention provides an embodiment: the utility model provides an explosion-proof fire damper that discharges fume, includes outer frame 1, the inside of outer frame 1 is equipped with interior frame 2, and the equal fixedly connected with slider 12 in both sides surface of interior frame 2, the inside wall of outer frame 1 is equipped with spout 11, and slider 12 is located the inside of spout 11, slider 12 and 11 sliding connection of spout, the rear end fixedly connected with spring 13 of slider 12, and the one end of spring 13 and the inner wall fixed connection of spout 11.
Further, the inside of internal frame 2 is equipped with and blocks blade 3, and blocks the equal fixedly connected with pivot 5 of the upper end of blade 3 and the lower extreme that blocks blade 3, and the one end of pivot 5 passes and blocks blade 3 and outer frame 1 swing joint, can be convenient for block blade 3 and close and open to ventilate when no conflagration, prevent stretching of conflagration when having the conflagration.
Further, frame 1 is inside to be equipped with control storehouse 6 outside, and the inside of control storehouse 6 is equipped with connecting rod 8, the fixed connection of connecting rod 8 one end and pivot 5, and the other end swing joint of connecting rod 8 has control lever 9, can drive the rotation that blocks blade 3 through connecting rod 8 and control lever 9 to be convenient for control blocks the switch of blade 3.
Further, the one end fixedly connected with spring 7 of control lever 9, and the one end of spring 7 and the inside wall fixed connection of control storehouse 6 can drive the motion of control lever 9 fast through spring 7 to can block that blade 3 closes fast through control lever 9.
