In one embodiment, described control latch fitting comprises housing, be provided with a L-type bull stick longitudinally in the described housing, the horizontal sidepiece of described L-type bull stick is provided with the annular groove that is beneficial to import lock pin, the vertical end of described L-type bull stick and a crank are hinged, described crank is hinged with the card driving lever that can vertically slide, described card driving lever is provided with the back-moving spring that is beneficial to upwards to reset and slides, described card driving lever one end arranges and to be beneficial to the handing end stirred with hand, described card driving lever is hinged with horizontal swing arm near a side of handing end, described swing arm one end is hinged on the housing base plate, pegs graft with normally open solenoid valve one magnetic core that is used for the control release in described swing arm the other end.
In one embodiment, the swing arm middle part of described control latch fitting is provided be used to the U-shaped block of clamping temperature sensing glass ball, the other end of described temperature sensing glass ball is provided with fixed block, be provided be used to the bolt that wears extension spring between described U-shaped block and the fixed block, described extension spring two ends are connected on fixed bar and the bolt.
In one implemented, described haulage chain was the loop chain type chain.The loop chain type chain is more convenient quick, is difficult for being broken, and common on the market.
The utility model has the advantage of: the one, the electric dual control of this labeled door temperature is closed a release and is provided with electronic control, can utilize electronic control at ordinary times, and is convenient and swift; The 2nd, set temperature induction control, in breaking out of fire under people have little time situation that electronic control or electronic control damages, by the time fire near the time temperature sensing glass ball quick bursting, the autoshutdown door-plate prevents that fire from further spreading; The 3rd, under emergency case, all in the malfunctioning situation, the fire fighter can utilize manual end to stir release to both controllers, can close door-plate in the same old way, for people's safety provides omnibearing guarantee.
