Description
Technical field
The invention belongs to fire prevention field, particularly one is caught fire from triggering fire resistance rolling shutter door, is applicable to the places such as megastore, warehouse and school.
Background technology
In the historical long river of human development, fire brings civilization and progress, light and warm to the mankind.But it is the mankind's friend sometimes, be the enemy of mankind sometimes.Out of control fire, will cause disaster to the mankind.Along with social development, when the wealth of society is increasing, cause the danger of breaking out of fire also increasing, the harmfulness of fire is also increasing.According to statistics, China's the 70's fire annual mean is lost less than 2.5 hundred million yuan, and the fire annual mean of the 80's is lost less than 3.2 hundred million yuan.Entered for the 90's, particularly, since 1993, the direct property loss that fire causes rises to average annual tens00000000 yuan, average annual dead people more than 2000.Fact proved, along with society and expanding economy, firemanic importance is just more and more outstanding." fire preventing and reduce the harm of fire " is the general overview to fire-fighting legislation meaning, comprised two layers of meaning: the one, carry out the work in every of fire preventing, and prevent fire; The 2nd, fire is absolutely not impossible, once and breaking out of fire just should be puted out a fire to save life and property in time, effectively, the harm of minimizing fire.How, in the time that fire just occurs, fire extinguishing is a great problem rapidly.Catch fire from triggering fire resistance rolling shutter door if can have, at very first time isolation burning things which may cause a fire disaster, stop fire spreading, this has major contribution to fire-fighting cause.
Summary of the invention
The object of the invention, has been to provide one and has caught fire from triggering fire resistance rolling shutter door, solves in the time that fire occurs nobody, puts down fire resistance rolling shutter door problem without electricity and people can not be close in the situation that.
The technical scheme adopting is:
One is caught fire from triggering fire resistance rolling shutter door, comprises fire resistance rolling shutter door and switch.
Its technical essential is:
Fire resistance rolling shutter door comprises fire-proof door curtain, door-hinge, left slideway and right slideway.
Fire-proof door curtain top edge is fixed winding on door-hinge, the assembling corresponding to left slideway of the left hand edge of fire-proof door curtain, the assembling corresponding to right slideway of the right hand edge of fire-proof door curtain.
Switch comprises switch body, fusible link, spring, roller, slide block and bayonet lock.
In switch body, be provided with spring and slide block, both ends of the spring is separately fixed on switch body and slide block.
In switch body, be wholely set card frame, one end of bayonet lock is fixed on slide block, and bayonet lock passes the first hole and second hole of card frame, and can in the first hole and the second hole, slide.
One end of fusible link is fixed on card frame, behind the 3rd hole of the other end of fusible link through card frame, is fixed on slide block, and spring is configured to fusible link has no progeny and draw slide block, and spring is in extended state.
The bayonet lock other end is equiped with roller.
Door-hinge two ends are installed on supporter by bearing respectively, and left slideway and right slideway are fixed on supporter symmetrically.
Switch body is fixed on supporter.
The top volume of fire-proof door curtain is located on door-hinge, and the roller on bayonet lock is fastened on fire-proof door curtain lower limb, and fire-proof door curtain is configured to bayonet lock and removes after the restriction of fire-proof door curtain, and fire-proof door curtain relies on gravity to fall.
Fusible link is nylon rope.
Described supporter is body of wall.The axis of bayonet lock and the surface of fire-proof door curtain are perpendicular.
Fusible link one end ties up on the joint pin in the groove on card frame, and the other end ties up on the joint pin in the groove on slide block.
In the time that fire occurs, fusible link blows rapidly in hot environment, spring contraction, and bayonet lock is pulled by spring, and bayonet lock is removed the constraint to fire-proof door curtain, and fire-proof door curtain declines until close under Action of Gravity Field.Completely cut off air, stoped fire spreading.
Its advantage is:
The present invention is can be in the time that fire occurs unmanned, put down fire-proof door curtain problem without electricity and people can not be close in the situation that, safe and reliable.
