Along with the maturation day by day of thermal cell technical development, the technical field of thermal cell application is also extensive all the more, the structural requirement of thermal cell is also varied, the thermal cell of conventional electro activation mode also more and more can not meet the instructions for use of various environment and special circumstances, and the thermal cell of mechanical activation mode is also more and more widely used.What the thermal cell of mechanical activation mode was the most conventional is impacting type fire in a stove before fuel is added mode, dividing plate device sparking mode and percussion drawing mode.
A kind of trigger type thermal battery activating device disclosed in Authorization Notice No. CN203607490U, its operation principle applies certain external force pin will be drawn to extract, be in spring and promote striker ejection, striker striking igniter cap makes it to excite, and the output medicine that ignites after igniter cap ignition can make battery enter operating state.The deficiency of this device is: ensure that spring needs to provide larger axial load to promote striker, thus require high to spring, easily cause activator appliance to take up room greatly; In addition, this device needs exterior mechanical to activate mechanism, can not excite thermal cell again by time delay certain hour after applying external force.
Summary of the invention
The technical problems to be solved in the utility model: provide a kind of without the need to external mechanical manipulation, simple to operate, take up room little, time delay certain hour after guarantee effect, promotes the active device of striker activation heat battery with larger load.
The technical solution of the utility model:
A kind of low overload type activation heat cell apparatus, comprise housing, firing pin, firing pin spring and stopping means, the central lumen oral area of described housing is provided with striker fixed muffle, and striker fixed muffle inside is disposed with firer's element, striker matrix, and striker matrix one end is provided with striker.
Above-mentioned striker fixed muffle and striker intrinsic silicon are provided with cuts pin.
Aforementioned stopping means is arranged in the eccentric inner chamber of housing, and the eccentric inner chamber of housing is communicated with by through hole with central lumen, is provided with the second spacing steel ball in through hole.
Aforementioned stopping means comprises inertia cylinder, inertia rod and inertia rod spring, and it is inner that inertia rod and inertia rod spring are successively set on inertia cylinder, and inertia rod spring one end is arranged on inertia rod, and one end is arranged on bottom inertia tube inner chamber.
Aforementioned stopping means also comprises fixed muffle, inertia cylinder spring and the first steel ball, it is outside that fixed muffle is arranged on inertia cylinder, inertia cylinder spring one end is arranged on inertia cylinder, and one end is arranged on fixed muffle intracavity bottom, and the first spacing steel ball is arranged on inertia cylinder both sides.
The beneficial effects of the utility model:
Compared with prior art, the utility model can obtain stronger axial load due to the energy discharged by firer's element, thus reduces the requirement to firing pin spring axial load, just can activation heat battery with very little stroke, reduces the volume of activator appliance; Adopt eccentric inner-cavity structure in addition, by the compression of inertia rod spring and the compression of the release of the first spacing steel ball and inertia cylinder spring and the release of the second spacing steel ball, both reached the effect of time-lag action, and turn reduced the volume of activator appliance; The utility model activates mechanism without the need to exterior mechanical, simple to operate, and reliability is high, is applicable to very much the needs of the flexibility mobility of armament systems.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
Embodiment of the present utility model: as shown in Figure 1, a kind of low overload type activation heat cell apparatus, comprise housing 9, housing 9 is processed with a central lumen, the through hole of an eccentric inner chamber and connection two inner chambers, firing pin 7 is provided with in central lumen, firing pin 7 outer setting limited impression, firing pin spring 8 one end is arranged on bottom housing 9 central lumen, the other end is arranged on firing pin 7, central lumen oral area arranges striker fixed muffle 2, striker fixed muffle 2 inside is disposed with firer's element 6, striker matrix 5, striker matrix 5 one end is provided with striker 3, striker matrix 5 is fixed in striker fixed muffle by cutting pin 4.
In the through hole that housing 9 is communicated with central lumen and eccentric inner chamber, the second spacing steel ball B2 is set for limiting firing pin 7 axial motion, the eccentric inner chamber of housing 9 is provided with the inertia cylinder 11 that the spacing steel ball B2 of triggering second moves, inertia cylinder 11 inside sets gradually inertia rod 10, inertia rod spring 12, inertia rod spring 12 one end is arranged on inertia rod 10, one end is arranged on bottom inertia cylinder 11, inertia cylinder 11 outer setting has fixed muffle 14, fixed muffle 14 inside arranges inertia cylinder spring 13, inertia cylinder spring 13 one end is arranged on inertia cylinder 11, one end is arranged on fixed muffle 14 intracavity bottom, inertia cylinder 11 both sides are provided with the first spacing steel ball B1.
Housing 9 and end cap 1 are bolted and fixed muffle 14, striker fixed muffle 2 are individually fixed in eccentric inner chamber and central lumen.
Operation principle of the present utility model is: when active device and thermal cell load after body launches, inertia safety mechanism is under the effect of continued rectilinear inertia force, inertia rod 10 compresses inertia rod spring 12, discharge the first spacing steel ball B1, inertia cylinder 11 compresses inertia cylinder spring 13 under lasting axial load factor effect, second spacing steel ball B2 of release constraint firing pin 7, the release with the release of the first spacing steel ball B1 and the compression of inertia cylinder spring 13 and the second spacing steel ball B2 is compressed by inertia rod spring 12, reach the effect of time-lag action, firer's element 6 exposed by firing pin 7 under the effect of firing pin spring 8, the energy that firer's element 6 discharges provides stronger Axial Loads to cut off in striker matrix 5 and cuts pin 4 and drive striker 3 to clash into ignitor to complete activator appliance function.
Firing pin spring 8 promotes firing pin 7 when clashing into firer's element 6, and its potential energy consumes except overcome friction except a part, and all the other all become the kinetic energy of firing pin 7.Frictional force energy ezpenditure easily causes firing pin 7 clamping stagnation to cause firing pin spring 8 slowly to move; loss stamp hits energy; therefore in order to ensure firing pin 7 kinematic dexterity; need strengthen controlling the inspection of housing 9 central lumen and firing pin 7 fineness; molybdenum bisuphide need be smeared to firing pin 7 surface simultaneously; to reduce firing pin 7 and the frictional force of housing 9 central lumen, ensure activator appliance reliable activation.
