Abstract
The invention relates to a fire-extinguishing switch based on fusible metal. The fire-extinguishing switch comprises a switch shell body, springs and a firing pin assembly, wherein a groove is formed in an upper end cover of the switch shell body, a connecting rod through hole is formed in the bottom wall of the groove, and a firing pin through hole and two fixing holes are formed in a lower end cover of the switch shell body; the firing pin assembly consists of a firing pin, a firing pin seat and a connecting rod, wherein the firing pin penetrates through the center hole of the firing pin seat and is fixedly connected with the firing pin seat, the firing pin and the firing pin seat are of an overall structure, and the lower end of the connecting rod is fixedly connected with the upper end of the firing pin; and the springs and the firing pin assembly are mounted in the switch shell body, the springs is sleeved on the connecting rod, and the upper end of the connecting rod penetrates through the connecting rod through hole in the bottom wall of the groove and is soldered in the groove through soldering tin. According to the fire-extinguishing switch based on the fusible metal, quick fire extinguishing can be achieved in an unattended case.
Description
Technical field
The invention belongs to the fire prevention field, particularly a kind of fire extinguishing switch based on fusible metal is applicable to fire extinguisher and Related product.
Background technology
In the historical long river of human development, fire brings civilization and progress, light and warm to the mankind.But it is human friend sometimes, is the enemy of mankind sometimes.Out of control fire will cause disaster to the mankind.Along with the continuous development of society, 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 loss is less than 2.5 hundred million yuan, and the 80's, fire annual loss was 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 that along with society and expanding economy, firemanic importance is just more and more outstanding." harm of fire preventing and minimizing fire " is to the general overview of fire-fighting legislation meaning, has comprised two layers of meaning: the one, carry out every work of fire preventing, and prevent fire; The 2nd, fire is impossible anything but, in case 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 when fire just took place, fire extinguishing was a great problem rapidly.If the fire of chance can be arranged from trigger switch, will have major contribution to the fire-fighting cause.
Summary of the invention
The object of the invention has provided a kind of fire extinguishing switch based on fusible metal, solves fire extinguishing problem under the unmanned situation.
The technical scheme that adopts is:
A kind of fire extinguishing switch based on fusible metal comprises switch case, spring and firing pin assembly.
Offer groove on the upper end cover of switch case, the connecting rod through hole is arranged on the diapire of groove, offer firing pin through hole and two fixing holes on the bottom end cover of switch case.
The firing pin assembly is made up of firing pin, striker post and connecting rod; Firing pin passes the centre bore of striker post, and fixedlys connected with striker post; Fixedly connected with the upper end of firing pin in the lower end of connecting rod.
Spring and firing pin assembly are installed in the switch case, and spring housing is contained on the connecting rod, and connecting rod passes the connecting rod through hole on the diapire of groove, the upper end of connecting rod by the scolding tin solid welding in groove.
The present invention is fixed on the fire extinguisher by fixing hole.
When fire took place, scolding tin is fusing rapidly in hot environment, and firing pin is flicked by spring, and firing pin triggers fire extinguisher, and fire extinguisher is opened.
Advantage and effect: by the enforcement of technical solution of the present invention, can be implemented under the unmanned situation and realize quick extinguishing.
