Description
Technical field
The invention belongs to fire extinguisher bomb technical field, particularly a kind of trigger mechanism based on expansion core fire extinguisher bomb fuse, be applicable to fire extinguishing shell for mortar fuse, pickaback howitzer fire extinguisher bomb fuse and relevant fire extinguisher bomb fuse product.
Background technology
Fire is the natural enemy of human survival, and the main cause that fire is wreaked havoc is that the speed of fire spreading is very fast, often when people have little time to put out a fire to save life and property or cannot put out a fire to save life and property near the scene of a fire for a certain reason, forms large area burning and causes heavy losses.Particularly many special fire are as the fire in forest, oil depot, chemicals storehouse and war fire, once burning people, cannot be close, and common fire-fighting equipment fire extinguishing must have people to operate in scene of fire, such as fire extinguisher and fire engines.If scene does not have fire extinguisher or fire engines cannot arrive within very short time, only has fire spreading soon, until burn down.Also put out a fire difficult blow-off velocity slowly even if arrive in, so how effectively to put out a fire fast, become the important topic resisting fire.The trigger mechanism that current fire extinguisher bomb adopts fuse has mechanical type triggering, delayed type triggering and ignition type triggering etc.Adopt the fire extinguisher bomb of mechanical type contact fuze fire extinguishing scope little, adopt the fire extinguisher bomb of delayed type contact fuze to be difficult to the delay time controlling to pre-set, adopt the fire extinguisher bomb reaction speed of ignition type contact fuze slow.If the trigger mechanism of fire extinguisher bomb fuse can quick and precisely detonation fire-fighting bomb, the extinguishing ability of fire extinguisher bomb will have breakthrough change.
The object of the invention, there is provided a kind of trigger mechanism based on expansion core fire extinguisher bomb fuse, solves fire extinguisher bomb effective Fire-fighting Problems fast.Change the trigger mechanism of fire extinguisher bomb fuse into trigger mechanism based on expansion core, significantly improve the extinguishing ability of fire extinguisher bomb.
The technical scheme adopted is:
Based on a trigger mechanism for expansion core fire extinguisher bomb fuse, comprise fuze body, firing pin lock, trigger and unlocking device.
Trigger room and unlocking device room is offered in fuze body.
Trigger room is communicated with unblock room.
Trigger comprises spring fastening, spring, slide block, firing pin and igniter cap.Igniter cap is fixed on bottom trigger room, spring pedestal is fixed on the top of trigger room, spring and slide block are installed in trigger indoor, spring one end is supported on spring pedestal, the other end is supported on slide block, slide block is pinned by firing pin, and firing pin through the hit pinhole in the middle part of slide block, and is fixedly connected with slide block.
Firing pin lock is made up of kayser, connecting rod and snap ring.Kayser is fixedly connected with the lower end of connecting rod, and small end is fixedly connected with snap ring.Kayser and fuze body hinged.When non-excited state.Kayser blocks slide block.
Unlocking device comprises expansion core, cylinder, hook, and hook is fixedly connected with cylinder diapire.Expansion core is installed in cylinder, and support spring is arranged on the bottom of unlocking device room; Cylinder and hook that expansion core is housed are installed in unblock indoor, and hook lower surface is supported on support spring, and snap ring is set on the gib head of hook.
Operation principle of the present invention:
Fire extinguisher bomb by mortar or pickaback howitzer launch, fire extinguisher bomb flies to scene of a fire expansion core undergoes rapid expansion in hot environment, expansion core extrusion cylinder, cylinder moves down together with hook, and the snap ring of bayonet lock upper end removes the constraint of hook to it, bayonet lock rotates counterclockwise, slide block removes bayonet lock to its constraint, compacted spring release, and firing pin is launched away percussion cap ignition charge, powder extinguishing agent is evenly blown, and dry powder covers burning things which may cause a fire disaster after on burning things which may cause a fire disaster and extinguishes.
Advantage and effect: by the enforcement of technical solution of the present invention, can effectively put out a fire fast, novel, reasonable, the safe and reliable good extinguishing effect of mechanism of the present invention simple designs, efficiently solves fast effectively extinguishment, avoids to greatest extent because of the loss caused not in time of putting out a fire.
