Lockset, the fire resistant doorsets top are equipped with door closer, and the other end of the door closer is fixedly connected at the top of the doorframe, described anti-
Vent is equipped with timing means,
The timing means includes wind-up timer, and the wind-up timer is fixedly connected on the one side of the fire resistant doorsets,
The output shaft of the wind-up timer is connected with sheave, and the side of the sheave is equipped with elastic switch, and the elastic switch is fixed to be connected
It connects on the inner wall of the fire resistant doorsets, the contact of the elastic switch side is equipped with the raised and described protrusion and the sheave
Engagement,
The fire resistant doorsets bottom is equipped with fixed iron piece, and the ground that the fire resistant doorsets open side is equipped with fixed device, institute
Stating fixed device includes guide rail, and the guide rail is embedded in ground, and sliding is equipped with fixed sliding block in the guide rail, described fixed sliding
Electromagnet is equipped in block, the electromagnet is connected by conducting wire with the elastic switch and power supply.
The fire resistant doorsets are equipped with observation window.
The number of the hinge for fireproof is three.
The beneficial effects of the utility model are: the fixation device of the utility model is adsorbed on fixed iron piece, can make to prevent fires
It is kept it turned in the door short time, to pedestrian and the people to transport goods is needed to bring conveniently, after reaching specified time, closed
Door device drives fire resistant doorsets to close and keep normally off, reduces the situation that human factor causes fire resistant doorsets normally opened, reduces peace
Full hidden danger.

Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples:
As shown, a kind of fire resistant doorsets of sustainable unlatching, including doorframe 1, the doorframe 1 are fixedly connected on wall
In door opening, side is hinged with fire resistant doorsets 2 by hinge for fireproof 3 in the doorframe 1, and the fire resistant doorsets 2 are not connected with the fire prevention hinge
The side of chain 3 is equipped with fire prevention lockset 4, is equipped with door closer 5 at the top of the fire resistant doorsets 2, the other end of the door closer 5 is fixedly connected
At 1 top of doorframe, the fire resistant doorsets 2 are equipped with timing means 6,
The timing means 6 includes wind-up timer 61, and the wind-up timer 61 is fixedly connected on the fire resistant doorsets 2
On one side, the output shaft of the wind-up timer 61 is connected with sheave 62, and the side of the sheave 62 is equipped with elastic switch 63, the bullet
Property switch 63 be fixedly connected on the inner wall of the fire resistant doorsets 2, the contact of 63 side of elastic switch is equipped with protrusion and institute
