Description
Technical field
A kind of trigger ignition device for solid oxygen generator belongs to the oxygen generator technical field, is specifically related to a kind of trigger ignition device for solid oxygen generator, and it is mainly used in instantaneous, safe, the reliable percussion igniting of solid oxygen generator.
Background technology
At present, along with pressing on military, civilian, solid oxygen generator obtains extensive concern both domestic and external and attention gradually.Because this product still is in research, advanced development, the performance difference of various products is bigger, and the percussion sparking mode also is not quite similar.The percussion sparking mode of the early production of solid oxygen generator generally adopts percussion igniting of knob bump or drag-line bump percussion igniting.The percussion of knob bump can make the solid oxygen generator oxygen source follow rotation in packaging case when the percussion igniting usually, thereby produces the phenomenon that misfires, and the igniting reliability of solid oxygen generator is descended greatly.Drag-line bump percussion igniting in the duties stage easy generation pull out drag-line because of carelessness and pull the trigger solid oxygen generator, can not guarantee duties safety.
Summary of the invention
Order of the present invention is for solving the deficiencies in the prior art, a kind of trigger ignition device for solid oxygen generator is provided, adopt the push button trigger ignition device, it can pull the trigger the igniter cap of solid oxygen generator quick under any environmental condition, safely, reliably, thereby pull the trigger each propagation of explosion sequence, guarantee instantaneous, reliable oxygen supply.
Technical scheme of the present invention is, a kind of trigger ignition device for solid oxygen generator, comprise firing pin spring, heat insulation loop, steel ball, sunk screw, button, baffle ring, the anti-spring that pushes away, also comprise body, lining, nut, safety plug, sliding sleeve, block, striker, be pressed into the inner chamber of body behind the striker insertion firing pin spring, body is connected with nut by screw thread in the bottom of nut; Anti-spring, lining, steel ball, baffle ring, sliding sleeve, safety plug, the button of pushing away packed into from the top of nut successively, covers block, and block is connected with nut by sunk screw; Nut is connected with heat insulation loop by screw thread.
The present invention also can be further perfect by following steps: on the striker afterbody cylinder annular groove is arranged, the slightly larger in diameter of striker head bead is in the internal diameter of body cavity.
Beneficial effect of the present invention:
1, the present invention adopts the mode percussion primer of push button abrupt release bump spring, after pulling out safety plug, only need give the button a slight press and just can discharge the insurance of striker afterbody steel ball, make firing pin spring promote striker high-speed motion percussion primer, guaranteed the reliability of solid oxygen generator igniter when the percussion igniting;
2, adopt safety plug, steel ball two-stage security insurance, guaranteed of the security of solid oxygen generator igniter in the duties stages such as assembling, transportation, storage, uses;
3, overall construction design is reasonable, has advantages such as easy to carry, easy and simple to handle, and She Ji heat insulation loop can play heat-blocking action simultaneously.
Description of drawings
The present invention has 1 width of cloth accompanying drawing, also is most preferred embodiment of the present invention, also can explain the accompanying drawing of book extract.
Fig. 1: be structural representation of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing most preferred embodiment of the present invention is described in further detail.
As shown in Figure 1, a kind of trigger ignition device of solid oxygen generator, comprise firing pin spring 2, heat insulation loop 3, steel ball 5, sunk screw 7, button 9, baffle ring 12, the anti-spring 13 that pushes away, also comprise body 1, lining 4, nut 6, safety plug 8, sliding sleeve 10, block 11, striker 14, be pressed into the inner chamber of body 1 behind the striker 14 insertion firing pin springs 2, on the striker 14 afterbody cylinders annular groove is arranged, the slightly larger in diameter of striker 14 head beads is in the internal diameter in body 1 chamber, and body 1 is connected with nut 6 by screw thread in the bottom of nut 6; The anti-spring 13, lining 4, steel ball 5, baffle ring 12, sliding sleeve 10, safety plug 8, button 9 of pushing away packed into from the top of nut 6 successively, covers block 11, and block 11 is mutually 120 ° of sunk screws 7 by three and is connected with nut 6; Nut 6 is connected with heat insulation loop 3 by screw thread.
Pull out safety plug 8 when operating personnel use, trigger ignition device is in arm-to-arm; As long as press the button 9, overcome the anti-pressure that pushes away spring 13 to downslide at the effect low sleeve 10 of manpower, sliding sleeve 10 actions put in place, steel ball 5 is extruded lining 4, and insurance is freed, and striker 14 is under the effect of firing pin spring 2, moment percussion cap is lighted the oxygen supply powder column of solid oxygen generator and is produced oxygen.
Adopt the dual fail-safe structure of horizontal slotting safety plug 8, steel ball 5 locking strikers 14, it is safe and reliable to have guaranteed that production, transportation, duties are handled.
In the duties stage, two steel balls 5 block striker 14 at the annular groove place of sliding sleeve 10 bayonet socket places embedding striker 14, make firing pin spring 2 be in compressive state.The trend of sliding sleeve 10 oriented and the motion of striker 14 rightabouts under the anti-effect that pushes away spring 13 of compression, this moment since the slightly larger in diameter of striker 14 head beads in the internal diameter in body 1 chamber, guaranteed that whole trigger ignition device makes time spent two steel balls 5 and block striker 14 and not landing at striker 14 annular groove places being subjected to external force, safety plug 8 blocks sliding sleeve 10 simultaneously, assurance fall or when pressing firing button 9 because of carelessness sliding sleeve 10 can not produce relative motion, guarantee the safety of trigger ignition device in the duties stage.When needs percussion solid oxygen generator, at first extract safety plug 8, press firing button 9 then, effect low sleeve 10 at manpower overcomes the anti-pressure of spring 13 that pushes away to glide (producing relative motion with the striker direction), because inertia, striker 14 keeps inactive state, and the steel ball 5 that two diameters that are in striker 14 annular groove places are Φ 2.5mm rolls out lining 4 under the effect of angular force, skid off striker 14 card nests smoothly, remove insurance striker 14; Striker 14 produces high-speed motion in effect following moment of firing pin spring 2, percussion cap, and igniter cap is got angry, and lights ignition powder, and the oxygen supply powder column that ignites, and produces oxygen; The oxygen supply powder column can produce a large amount of heats when in solid oxygen generator chemical reaction taking place, and at this moment, the heat insulation loop 3 of trigger ignition device can play heat-blocking action.
