Abstract
The invention relates to a fire-extinguishing switch based on a swelling core. The fire-extinguishing switch comprises a switch shell body, the swelling core, a circular tube, a firing pin and springs, and is characterized in that a firing pin through hole and two mounting holes are formed in a lower end cover of the switch shell body; and the swelling core, the circular tube, the firing pin and the springs are mounted in the switch shell body, the swelling core is arranged in the circular tube, the upper end of the firing pin is fixedly connected with the bottom wall of the circular tube, the springs are sleeved on the firing pin, the lower end of the firing pin extends out of the firing pin through hole in the lower end cover, the upper ends of the springs are abutted against the bottom wall of the circular tube, and the lower ends of the springs are abutted against the lower end cover of the switch shell body. The fire-extinguishing switch based on the swelling core has the advantage and effect that 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 the expansion core 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 the expansion core, solves fire extinguishing problem under the unmanned situation.
The technical scheme that adopts is:
A kind of fire extinguishing switch based on the expansion core comprises switch case, expansion core, cylinder, firing pin and spring.
Firing pin through hole and two installing holes are arranged on the bottom end cover of switch case.
Expansion core, cylinder, firing pin and spring are installed in the switch case, the expansion core places in the cylinder, fixedly connected with the diapire of cylinder in the upper end of firing pin, spring housing is contained on the firing pin, the firing pin through hole on the bottom end cover is stretched out in the lower end of firing pin, the upper end of spring is replaced on the diapire of cylinder, and the lower end of spring is replaced on the bottom end cover of switch case.
Above-mentioned expansion core is the vermiculite core.
When fire took place, the expansion core expanded rapidly in hot environment, and expansion core extrusion cylinder, cylinder promote firing pin and move down, and firing pin is launched away the percussion cap ignition charge, and powder extinguishing agent is evenly blown, and burning things which may cause a fire disaster extinguished after dry powder covered on the burning things which may cause a fire disaster.
The present invention is fixed on the fire extinguisher by fixing hole.
When fire took place, the expansion core expanded rapidly in hot environment, and firing pin is extruded and moves down, 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.
Description of drawings
Fig. 1 is schematic appearance of the present invention.
Fig. 2 is structural representation of the present invention.
The specific embodiment:
A kind of fire extinguishing switch based on the expansion core comprises switch case 1, expansion core 2, cylinder 3, firing pin 4 and spring 5.
Firing pin through hole 7 and two installing holes 8 are arranged on the bottom end cover 6 of switch case 1.
Expansion core 2, cylinder 3, firing pin 4 and spring 5 are installed in the switch case 1, expansion core 2 places in the cylinder 3, fixedly connected with the diapire 9 of cylinder 3 in the upper end of firing pin 4, spring 5 is sleeved on the firing pin 4, the firing pin through hole 7 on the bottom end cover 6 is stretched out in the lower end of firing pin 4, the upper end of spring 5 is replaced on the diapire 9 of cylinder 3, and the lower end of spring 5 is replaced on the bottom end cover 6 of switch case 1.
Above-mentioned expansion core 2 is the vermiculite core.
When fire took place, expansion core 2 expanded rapidly in hot environment, expansion core 2 extrusion cylinders 3, cylinder 3 promotes firing pin 4 and moves down, firing pin 4 is launched away the percussion cap ignition charge, and powder extinguishing agent is evenly blown, and burning things which may cause a fire disaster extinguished after dry powder covered on the burning things which may cause a fire disaster.
