A kind of fire resisting damper, referring to Fig. 1, including outline border 100 and several blinkers 110 on outline border 100, specifically
, in conjunction with Fig. 2, fire resisting damper can be embedded in ventilation shaft 200, pass through bolt 101 and the ventilation shaft being arranged on outline border 100
The spliced eye 201 corresponding with above-mentioned bolt 101 being arranged on 200, and by bolt 101 with spliced eye 201 is mating makes
Fire resisting damper is obtained to be fixed in ventilation shaft 200；Specifically, outline border 100 is surrounded by groove 102, bolt 101 is plugged in the groove
In 102, and compressed spring 103 is equipped between 102 bottom of 101 bottom of bolt and groove, 103 both ends of compressed spring are fixed respectively to be connected
It is connected to 102 bottom of 101 bottom of bolt and groove.
Above-mentioned groove 102 is stretched out in one end of bolt 101, and after forcing in above-mentioned external part, which can house completely
In in groove 102, and under the action of 103 elastic-restoring force of compressed spring, one end of bolt 101 can be embedded in spliced eye 201,
To limit the separation of outline border 100 and ventilation shaft 200.And since 103 both ends of compressed spring are respectively fixedly connected in bolt
102 bottom of 101 bottoms and groove so that when bolt 101 is plugged in spliced eye 201, bolt 101 by compressed spring 103 bullet
Power makes bolt 101 be maintained at stretching state, and is not easy to fall, and fire resisting damper is made more securely to be mounted in ventilation shaft 200；When need
When by fire resisting damper detachable maintaining, pressing bolt 101 makes in 101 retraction groove 102 of bolt, to which bolt 101 is detached from spliced eye
201, so that outline border 100 is detached with ventilation shaft 200.
Bolt 101 is fixed on by compressed spring 103 in groove 102, and bolt 101 is in stretching state at this time, will prevent fires
When valve is embedded in ventilation shaft 200, needs that bolt 101 is first compressed to compressive state, fire resisting damper could be embedded in ventilation shaft
200, by the way that the inclined surface 1011 in bolt 101 far from 102 one end of groove and backwards to 100 front end 106 of outline border is arranged so that installation
When fire resisting damper, inclined surface 1011 is contradicted with ventilation shaft 200, while being pushed away by the installation on 200 length direction of ventilation shaft
Power, and it is in compressive state so that bolt 101 is pressurized, and has further facilitated the installation of fire resisting damper.
100 outer surface of outline border is enclosed with fire-retardant expansion core material 104, and the fire-retardant expansion core material 104 is butted on ventilation shaft
200 inner walls.Fire-retardant expansion core material 104 expands and blocks the gap between fire resisting damper and ventilation shaft 200 when encountering high temperature,
High-temperature flue gas is prevented to enter ventilation shaft 200；And rib is equipped with close to 200 air outlet side of ventilation shaft by outline border 100
105, which is butted on 200 air outlet end of ventilation shaft, makes the gap sealing between air outlet end and fire resisting damper, into
One step prevents high-temperature flue gas by entering ventilation shaft 200 at gap.
In conjunction with Fig. 1 and Fig. 3, above-mentioned fire resisting damper further includes blinker 110, which is equipped with rotary shaft 111,
Distinguish rotatable engagement and be mounted on the side wall of outline border 100 in 111 both ends of rotary shaft.Under normal circumstances, fire resisting damper is in open shape
State, blinker 110 are parallel to 100 side wall of outline border, are convenient for air circulation；When encountering fire, by blinker 110 around rotary shaft
111 rotations make the two panels blinker 110 positioned at most both ends be butted on the postive stop baffle 112 being arranged in 100 both sides of outline border respectively, this
When fire resisting damper close, prevent high-temperature flue gas from entering ventilation shaft 200.Specifically, in conjunction with Fig. 4, the both sides point of the blinker 110
Not She Zhi bending sticking part 113, make fire resisting damper in off position when, the bending sticking part 113 of adjacent two panels blinker 110 is distinguished
Gluing, sealing improves the leakproofness between adjacent two panels blinker 110.
The above is only the preferred embodiment of the utility model, and the scope of protection of the utility model is not limited merely to
Above-described embodiment, technical solution belonging to the idea of the present invention belong to the scope of protection of the utility model.It should refer to
Go out, for those skilled in the art, it is without departing from the principle of the utility model it is several improvement and
Retouching, these improvements and modifications also should be regarded as the scope of protection of the utility model.
