Detailed description of the invention
Below with reference to accompanying drawing, the utility model is described in detail, as shown in figs 1-9: a kind of fire-extinguishing shell launcher, comprise gun barrel 1, percussion lock 2, take aim at tool 3 and the transmitting cover 4 being arranged on gun barrel tail end, described gun barrel is made up of aluminium alloy, described percussion lock comprises housing 201, the button 202 be slidably connected with housing and sliding or static bearing pin 203 relative to housing for control button, the power supply 204 and circuit board 205 that are electrically connected to each other is provided with in described housing, described button is provided with the first contact 206 and the second contact 207, back-moving spring 208 is provided with between button and housing, described circuit board is provided with the first contact 209 and the second contact 2010, described bearing pin offers chute 2011, described tool of taking aim at comprises substrate 301 and slide block 302, described substrate is provided with dovetail groove 303, described slide block mates with dovetail groove and is slidably connected with dovetail groove, slide block is provided with optical sight 304, described substrate locks with being undertaken being connected by lock-screw 5 between slide block, the one side that described substrate contacts with gun barrel is provided with arc groove 305, the internal diameter of described arc groove is less than the external diameter of gun barrel, the both sides of described substrate are provided with hold-down screw 6, hold-down screw is arranged on position placed in the middle, both sides usually, described transmitting cover comprises body 401, two contacts 402 are detachably provided with in described body, described two contacts are electrically connected with circuit board respectively by wire.The fire-extinguishing shell launcher of this structure, possesses following advantage: 1) gun barrel is made up of aluminium alloy, lightweight, effectively can save muscle power, 2) during percussion, the contact that two contacts of fire extinguisher bomb tail end are corresponding with in body respectively, rotating pin, make the block on chute alignment button, block can along slide, such button just can slide by housing relatively, button moves drive first contact and the second contact moves, when the first contact and the first contact or the second contact and the second contact or the first contact and the first contact and the second contact and the second contact all can make cocking circuit conducting, fire extinguisher bomb is launched, namely this percussion lock constructs two cocking circuits, when certain contact (the first contact or the second contact) and certain contact (the first contact or the second contact) loose contact, all can ensure a cocking circuit conducting, thus fire extinguisher bomb is launched, therefore the reliability of percussion process can be improved, simultaneously, only have when bearing pin turns to the correct position (block namely on chute alignment button, make block can along slide), button could slide, be equivalent to bearing pin and play safety effect, the probability that mistakenly hit is sent out can be reduced, 3) setting taking aim at tool can improve launch accuracy, when substrate is arranged on gun barrel, because the internal diameter of arc groove is less than the external diameter of gun barrel, so can not fit tightly between arc groove and gun barrel wall, arc groove both sides are only had to contact with gun barrel wall, gap is there is between arc groove central authorities and gun barrel wall, hold-down screw penetrates substrate and is screwed into gun barrel wall, realize substrate to be arranged on gun barrel with this, in the process of tightening hold-down screw, because the internal diameter of arc groove is less than the external diameter of gun barrel, prestressing force can be produced, arc groove both sides are made to have the trend compressing gun barrel wall all the time, therefore the fixed effect between substrate and gun barrel wall can be ensured, and only need two hold-down screws just can realize firm connection, for convenience detach, subsequently according to the requirement of different launching crew, loosen lock-screw, promote slide block to move along dovetail groove, the i.e. distance of the relative gun barrel of adjustable optical sight, so that different launching crews is aimed at by optical sight, after adjusting to correct position, the connection realized between substrate and slide block by lock-screw is locked.In sum, the fire-extinguishing shell launcher of this structure, has assembly and disassembly convenience, launch accuracy is high, aiming efficiency is high, percussion reliability is high and mistakenly hit sends out the low advantage of rate.
As the further improvement to technique scheme, described circuit board is provided with indicator lamp 2012, emission lamp 2013 and indicator cock 2014, described power supply, indicator cock and indicator lamp are connected into indicating circuit, shown indicator cock controls conducting and the disconnection of cocking circuit simultaneously, during indicator cock conducting, indicator lamp is bright, when only having indicator cock conducting simultaneously, button slip ability conducting cocking circuit, indicator cock is utilized to play dual fail-safe effect, indicator lamp plays indicative function, when button drives the first contact and the first contact or the second contact and the second contact, emission lamp is bright, play reminding effect.
Above-mentioned cocking circuit and indicating circuit are custom circuit, are not described in detail here.
As the further improvement to technique scheme, gun barrel is detachably provided with the buttstrap 7 be made up of timber near tail end, described buttstrap is provided with deep-slotted chip breaker 8, described arc cell wall is provided with the air bag cushion 9 mated with deep-slotted chip breaker, also comprise gas cell 10, described gas cell is communicated with air bag cushion by airsac tube 11, described airsac tube is provided with valve 12.In emission process, air bag cushion contacts with launching crew's shoulder, the aeration quantity in air bag cushion can be regulated according to the width of launching crew's shoulder (or size), make air bag cushion and shoulder tight clamping fit, in order to cylindrical shell is reliably fixed on shoulder, to improve launch accuracy, in addition, air bag cushion also available buffer launch time impulsive force, reduce impulsive force to the impact of launching crew.
As the further improvement to technique scheme, between described two contacts, wire 13 is provided with resistive element 14.Between two contacts, resistive element is set by wire, the resistance of described resistive element is very large, off-state is equivalent to concerning cocking circuit, therefore percussion process is not affected, the instantaneous pressure only having electrostatic to produce is just by this resistive element, be equivalent to this resistive element Electro-static Driven Comb to be fallen, can reduce because electrostatic exists and occur the probability that mistakenly hit is sent out.
As the further improvement to technique scheme, described body outer wall is provided with cannelure 403, be provided with C type in described cannelure and encircle 404 and two contacts, the internal diameter that described C type is encircled is less than the diameter of annular groove bottom arc surface, the two ends that C type is encircled compress corresponding contact respectively, C type is encircled and is undertaken being connected locking by lock-screw 5 between cannelure, and described two contacts all stretch in body through cover body wall, and described C type is encircled and is made up of elastomeric material.The internal diameter encircled due to C type is less than the diameter of annular groove bottom arc surface, can not fit tightly so C type is encircled with annular groove bottom, in the process of tightening lock-screw, prestressing force can be produced, make C type encircle two ends and have the trend compressing contact all the time, therefore the fixed effect of contact can be ensured, contact not easily loosens, the contact effect of contact and fire extinguisher bomb tail end contact can be ensured, further increase the reliability of percussion process, and only need unclamp a lock-screw, take off C type and encircle and contact can be taken off, convenient disassembly.
As the further improvement to technique scheme, described contact comprises coaxial cylinder 4021, cone 4022 and spheroid 4023.Contact on spheroid and fire extinguisher bomb, makes motion flexible, does not have stuck point.
