Abstract
The utility model discloses a fire -extinguishing bullet launcher trigger device, including the casing, with casing sliding connection's button with be used for the relative casing of control button to slide or static round pin axle, be provided with power and circuit board that mutual electricity is connected in the casing, be provided with first contact and second contact on the button, be provided with reset spring between button and the casing, be provided with first contact and second contact on the circuit board, sell the epaxial spout of having seted up. The fire -extinguishing bullet launcher trigger device of this structure can not only improve the reliability of percussion process, can reduce the probability that the mistake percussion appears and cause the incident moreover.
Description
Technical field
The utility model relates to fire distinguisher technical field, is specifically related to a kind of fire-extinguishing shell launcher percussion lock.
Background technology
Fire extinguishing occupies very consequence in whole world economy, forest fire, prairie fire, oil tank catch fire and high-rise fire every year to China and human society cause direct, indirectly economic loss be all unable to estimate.
In the prior art; in order to more protect the personal safety of fire extinguishing personnel; have employed a kind of fire-extinguishing shell launcher to put out a fire; extinguish material is filled in bullet; utilize the form of mortar or rocket launcher to be transmitted in the scene of a fire by extinguish material, protect the personal safety of fire extinguishing personnel fully.Current fire-extinguishing shell launcher, comprise gun barrel and the transmitting cover being arranged on gun barrel tail end, described transmitting cover comprises body, and be detachably provided with two contacts in body, described contact is electrically connected with percussion lock.During transmitting, two contacts of fire extinguisher bomb tail end respectively with corresponding contact, the cocking circuit of then conducting percussion lock, can launch fire extinguisher bomb.There is following defect in the percussion lock of prior art: in 1) percussion process, the relative housing of firing button slides, make percussion contact and percussion contact, thus conducting cocking circuit, but usually only construct a cocking circuit, when long-time use, percussion contact abrasion or other reasons, the easy phenomenon occurring percussion contact and percussion poor contact of contacts, thus make percussion malfunctioning, reduce the reliability of percussion process; 2) button easily relatively housing be free to slide and cause mistakenly hit and find to resemble.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of fire-extinguishing shell launcher percussion lock, can not only improve the reliability of percussion process, and can reduce and occur that mistakenly hit is sent out and causes the probability of security incident.
The utility model is solved the problem by following technological means: a kind of fire-extinguishing shell launcher percussion lock, the button comprise housing, being slidably connected with housing and sliding or static bearing pin relative to housing for control button, the power supply be electrically connected to each other and circuit board is provided with in described housing, described button is provided with the first contact and the second contact, back-moving spring is provided with between button and housing, described circuit board is provided with the first contact and the second contact, described bearing pin offers chute.
Further, described circuit board is provided with indicator lamp, emission lamp and indicator cock, described power supply, indicator cock and indicator lamp are connected into indicating circuit, and shown indicator cock controls conducting and the disconnection of cocking circuit simultaneously.
Further, described first contact and the second contact are all threaded with button.
The beneficial effects of the utility model: fire-extinguishing shell launcher percussion lock of the present utility model, the button comprise housing, being slidably connected with housing and sliding or static bearing pin relative to housing for control button, the power supply be electrically connected to each other and circuit board is provided with in described housing, described button is provided with the first contact and the second contact, back-moving spring is provided with between button and housing, described circuit board is provided with the first contact and the second contact, described bearing pin offers chute.The fire-extinguishing shell launcher percussion lock of this structure, can not only improve the reliability of percussion process, and can reduce and occur that mistakenly hit is sent out and causes the probability of security incident.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further described.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the partial structurtes schematic diagram of Fig. 1.
Detailed description of the invention
Below with reference to accompanying drawing, the utility model is described in detail, as shown in Figure 1-2: a kind of fire-extinguishing shell launcher percussion lock, comprise housing 1, the button 2 be slidably connected with housing and sliding or static bearing pin 3 relative to housing for control button, the power supply 4 and circuit board 5 that are electrically connected to each other is provided with in described housing, described button is provided with the first contact 6 and the second contact 7, described first contact and the second contact are all threaded with button, back-moving spring 8 is provided with between button and housing, described circuit board is provided with the first contact 9 and the second contact 10, described bearing pin offers chute 11.During percussion, described circuit board is derived two lead-in wires to be connected respectively with two contacts that transmitting puts, 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, in addition, 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, therefore effectively can reduce and occur that mistakenly hit is sent out and causes the probability of security incident.
As the further improvement to technique scheme, described circuit board is provided with indicator lamp 12, emission lamp 13 and indicator cock 14, 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.
What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
