The invention belongs to the field of fire-fighting equipment, and provides a fire extinguishing bullet firing device launching under a low chamber pressure to realize reliable firing of a firing device by releasing mechanical lock under the low chamber pressure. The fire extinguishing bullet firing device comprises a tail piece, a push plate, a base, a connecting piece, a firing pin seat, a firing pin, a safety pin, a detonating cap and a delay tube. During launching, thrust force of the chamber pressure on the firing pin is delivered onto the firing pin after being amplified by the push plate, the safety pin is sheared, the firing pin is pushed forward to collide the detonating cap, the delay tube is ignited after firing of the detonating cap, and the mechanical lock is released by means of the low chamber pressure, thereby enabling the firing device to fire reliably.
Description
Technical field
The invention belongs to fire-fighting equipment field, be specifically related to a kind of fire extinguisher bomb sparking gear of low gun pressure transmitting.
Background technology
Fire extinguisher bomb is a kind of effective Fire Extinguisher, higher to its security requirement; Self,, with the mechanical firing device of safeties, has the advantages that reliability is high, security is good, is the ideal chose of individual soldier's fire extinguisher bomb.In order to improve the safety in utilization of system, the transmitting gun pressure of some emission system is lower, and the energy shortage that gun pressure provides, to remove the machine insurance of firing device, makes the reliability decrease of fire extinguisher bomb.
In view of the foregoing, how developing a kind of fire extinguisher bomb machinery sparking gear that low gun pressure just can launch that relies on, to those skilled in the art, is the direction and goal in the urgent need to striving for very.
Summary of the invention
(1) technical problem that will solve
The technical problem to be solved in the present invention is to provide a kind of fire extinguisher bomb machinery sparking gear of low gun pressure transmitting, solves by low gun pressure and removes machine insurance, makes the reliable technical barrier of getting angry of sparking gear.
(2) technical scheme
For solving the problems of the technologies described above, the invention provides a kind of fire extinguisher bomb machinery sparking gear of low gun pressure transmitting, it is characterized in that: this device comprises tail part, push pedal, base, connector, striker post, firing pin, safety plug, igniter cap and Delay Tube, described igniter cap is fitted in the heavy caliber end of Delay Tube; Delay Tube is threaded with connector; Connector is connected with whorl of base; Firing pin is loaded on the striker post inside that is provided with pin-and-hole, and safety plug penetrates pin-and-hole by striker post and firing pin location, and the body that attaches together of striker post, firing pin and safety plug is threaded with connector; Push pedal is loaded on base inside; Tail part is connected with whorl of base, pushes down push pedal, and push pedal is contacted with firing pin bottom.
Wherein, the external diameter of described push pedal cylindrical portion is definite according to thrust requirements and real space, and its cylindrical portion length is definite according to its axially-movable guiding and positioning function, and its round platform span access location length is determined according to the stroke of firing pin percussion cap.
Wherein, the length of described safety plug is identical with the external diameter of striker post.
Wherein, the diameter of described safety plug and material are selected by calculating according to machine insurance intensity.
Wherein, described striker post, firing pin and safety plug are selected the metal material that deformation coefficient is less; Described tail part, push pedal and base are selected the plastic material that proportion is less.
(3) beneficial effect
Compared with prior art, the present invention possesses following beneficial effect:
When 1, the present invention installs, by safety plug, firing pin is located, system is in insurance filling; During transmitting, the impulsive force providing by gun pressure is sheared safety plug, drives firing pin percussion primer, lights Delay Tube; Can effectively solve by low gun pressure and remove machine insurance, make the reliable technical barrier of getting angry of sparking gear.
Accompanying drawing explanation
Fig. 1 is the structural representation of the fire extinguisher bomb machinery sparking gear of low gun pressure transmitting provided by the invention.
The specific embodiment
For making object of the present invention, content and advantage clearer, below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.
As shown in Figure 1, the fire extinguisher bomb machinery sparking gear of low gun pressure transmitting provided by the invention, this device comprises tail part 1, push pedal 2, base 3, connector 4, striker post 5, firing pin 6, safety plug 7, igniter cap 8 and Delay Tube 9, and described igniter cap 8 is fitted in the heavy caliber end of Delay Tube 9; Delay Tube 9 is threaded with connector 4; Connector 4 is threaded with base 3; Firing pin 6 is loaded on striker post 5 inside that are provided with pin-and-hole, and safety plug 7 penetrates pin-and-hole by striker post 5 and firing pin 6 location, and the body that attaches together of striker post 5, firing pin 6 and safety plug 7 is threaded with connector 4; Push pedal 2 is loaded on base 3 inside; Tail part 1 is threaded with base 3, pushes down push pedal 2, and push pedal 2 is contacted with firing pin 6 bottoms.Make thus whole sparking gear in relatively-stationary safety position.
According to mechanics formula: thrust F=pressure P * area S, the function of push pedal 2 is that the impulsive force that gun pressure is acted on firing pin 6 is amplified, during transmitting, gun pressure is delivered on firing pin 6 after the thrust of firing pin 6 is amplified by push pedal 2, shear safety plug 7, promote firing pin 6 percussion cap 8 that travels forward, igniter cap 8 is lighted Delay Tube 9 after getting angry.Wherein, the external diameter of described push pedal 2 cylindrical portion is definite according to thrust requirements and real space, and its cylindrical portion length is definite according to its axially-movable guiding and positioning function, and its round platform span access location length is determined according to the stroke of firing pin 6 percussion caps 8.
Wherein, the length of described safety plug 7 is identical with the external diameter of striker post 5.
Wherein, the diameter of described safety plug 7 and material are selected by calculating according to machine insurance intensity.
Wherein, described striker post 5, firing pin 6 and safety plug 7 are selected the metal material that deformation coefficient is less; Described tail part 1, push pedal 2 and base 3 are selected the plastic material that proportion is less.
The inapplicable gun pressure of this sparking gear is too small, caliber is limited causes push pedal gun pressure can not be converted in the system of shearing safety plug and the required power of percussion primer.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the technology of the present invention principle; can also make some improvement and distortion, these improvement and distortion also should be considered as protection scope of the present invention.
