Installed surface shape and the step trough shape of fusing pedestal match, and the fusing pedestal offers a plurality of installing holes, is bolted to connection with the screwed hole of step trough.
Offer cylindrical hole in the fusing pedestal, described cylindrical hole is connected with tie rod hole.
L type bayonet lock is hinged on the fuze body by hinge.
L type bayonet lock one end is positioned at the slide block below and blocks slide block, and the L type bayonet lock other end and pull bar are hinged.
The pull bar right-hand member is positioned at described cylindrical hole, and is fixed in the ladder weld groove that the cylindrical hole inwall offers by scolding tin, forms solder joint.
Fire extinguisher bomb is by mortar or after howitzer is launched pickaback, fire extinguisher bomb arrives the scolding tin fusing rapidly in hot environment on the fuse body of the scene of a fire, pull bar is connected back L type bayonet lock and unmuzzles with the disconnection of ladder weld groove, compacted spring discharges, firing pin is launched away the percussion cap ignition charge, 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 material of fuze body and fusing pedestal can be selected plastics or metal etc. as required.
Its advantage is:
By the enforcement of technical solution of the present invention, can effectively put out a fire fast, mechanism of the present invention simple designs novelty, reasonable, safe and reliable good extinguishing effect efficiently solve fast an effectively fire extinguishing difficult problem, have avoided to greatest extent because of the untimely loss that causes of putting out a fire.
