Description
Technical field
The invention belongs to fire-fighting equipment field, be specifically related to the fire extinguisher bomb sparking gear that a kind of low gun pressure is launched.
Background technology
Fire extinguisher bomb is a kind of effectively Fire Extinguisher, higher to its security requirement; With the mechanical firing device of safeties, self has the advantages that reliability is high, security is good, be 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 relying on low gun pressure just can launch, to those skilled in the art, is the direction and goal very in the urgent need to striving for.
Summary of the invention
(1) technical problem that will solve
The technical problem to be solved in the present invention is to provide the fire extinguisher bomb machinery sparking gear that a kind of low gun pressure is launched, and solves and removes machine insurance by low gun pressure, make the technical barrier that sparking gear is reliably got angry.
(2) technical scheme
For solving the problems of the technologies described above, the invention provides the fire extinguisher bomb machinery sparking gear that a kind of low gun pressure is launched, it is characterized in that: this device comprises tailpiece, 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; It is inner that firing pin is loaded on the striker post being provided with pin-and-hole, and safety plug penetrates pin-and-hole by striker post and firing pin location, is threaded by the body that attaches together of striker post, firing pin and safety plug with connector; Push pedal is loaded on chassis interior; Tailpiece is connected with whorl of base, pushes down push pedal, and push pedal is contacted with bottom firing pin.
Wherein, the external diameter of described push pedal cylindrical portion is determined according to thrust requirements and real space, and its cylindrical portion length is determined 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 selected by calculating according to machine insurance intensity.
Wherein, described striker post, firing pin and the safety plug metal material of selecting deformation coefficient less; The plastic material that described tailpiece, push pedal and base select proportion less.
(3) beneficial effect
Compared with prior art, the present invention possesses following beneficial effect:
1, when the present invention installs, located by firing pin by safety plug, system is in insurance filling; During transmitting, the impulsive force provided by gun pressure shears safety plug, drives firing pin percussion primer, lights Delay Tube; Effectively can solve and remove machine insurance by low gun pressure, make the technical barrier that sparking gear is reliably got angry.
Accompanying drawing explanation
Fig. 1 is the structural representation of the fire extinguisher bomb machinery sparking gear that low gun pressure provided by the invention is launched.
Detailed description of the invention
For making object of the present invention, content and advantage clearly, 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 that low gun pressure provided by the invention is launched, this device comprises tailpiece 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; It is inner that firing pin 6 is loaded on the striker post 5 being provided with pin-and-hole, and safety plug 7 penetrates pin-and-hole and striker post 5 and firing pin 6 located, and is threaded by the body that attaches together of striker post 5, firing pin 6 and safety plug 7 with connector 4; It is inner that push pedal 2 is loaded on base 3; Tailpiece 1 is threaded with base 3, pushes down push pedal 2, and push pedal 2 is contacted with bottom firing pin 6.Whole sparking gear is made to be in relatively-stationary safety position thus.
According to force equation: thrust F=pressure P × area S, the function of push pedal 2 is that the impulsive force acted on by gun pressure on firing pin 6 is amplified, during transmitting, gun pressure is delivered on firing pin 6 after being amplified by push pedal 2 thrust of firing pin 6, shear safety plug 7, promote firing pin 6 to travel forward percussion cap 8, igniter cap 8 lights Delay Tube 9 after getting angry.Wherein, the external diameter of described push pedal 2 cylindrical portion is determined according to thrust requirements and real space, and its cylindrical portion length is determined 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 cap 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 selected by calculating according to machine insurance intensity.
Wherein, described striker post 5, firing pin 6 and safety plug 7 metal material of selecting deformation coefficient less; The plastic material that described tailpiece 1, push pedal 2 and base 3 select proportion 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 shearing power needed for safety plug and 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, under the prerequisite not departing from the technology of the present invention principle; can also make some improvement and distortion, these improve and distortion also should be considered as protection scope of the present invention.
