Abstract
The utility model discloses a fire -extinguishing bullet launcher barrel, the novel nipple rectifier comprises a cylindrical shel, the barrel is made by the aluminum alloy, the barrel is close to the tail end and is provided with the shoulder support of being made by timber, the shoulder holds in the palm can dismantle with the barrel through the screw to be connected, is provided with and launches the arc wall of personnel's shoulder contact on the shoulder holds in the palm. The fire -extinguishing bullet launcher barrel of this structure in the fire extinguishing bomb emission process, can not only improve the transmission precision, can save physical power moreover.
Description
Technical field
The utility model relates to fire distinguisher technical field, is specifically related to a kind of fire-extinguishing shell launcher gun barrel.
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 emitter 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.In prior art, in the process that mode gun barrel being shouldered similar rocket launcher piggyback launching crew launches fire extinguisher bomb, on the one hand, because gun barrel is normally made up of iron or steel, weight is large, emission process, and expend muscle power large, labour intensity is large; On the other hand, because gun barrel does not have fixture, precision is caused to reduce.
Utility model content
In view of this, the purpose of this utility model improves the gun barrel of prior art, provides a kind of and can not only improve launch accuracy in emission process, and can save the fire-extinguishing shell launcher gun barrel of muscle power.
The utility model is solved the problem by following technological means: a kind of fire-extinguishing shell launcher gun barrel, comprise cylindrical shell, described cylindrical shell is made up of aluminium alloy, described cylindrical shell is provided with the buttstrap be made up of timber near tail end, described buttstrap is removably connected by screw and cylindrical shell, buttstrap is provided with the deep-slotted chip breaker contacted with launching crew's shoulder.
Further, described arc cell wall is provided with the air bag cushion mated with deep-slotted chip breaker, also comprises gas cell, described gas cell is communicated with air bag cushion by airsac tube, and described airsac tube is provided with valve.
Further, described cylinder body outer wall is provided with locating ring, described buttstrap is provided with the locating slot mated with locating ring.
The beneficial effects of the utility model: fire-extinguishing shell launcher gun barrel of the present utility model, comprise cylindrical shell, described cylindrical shell is made up of aluminium alloy, described cylindrical shell is provided with the buttstrap be made up of timber near tail end, described buttstrap is removably connected by screw and cylindrical shell, buttstrap is provided with the deep-slotted chip breaker contacted with launching crew's shoulder.The fire-extinguishing shell launcher gun barrel of this structure, in fire extinguisher bomb emission process, can not only improve launch accuracy, and can save muscle power.
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.
Detailed description of the invention
Below with reference to accompanying drawing, the utility model is described in detail, as shown in Figure 1: a kind of fire-extinguishing shell launcher gun barrel, comprise cylindrical shell 1, described cylindrical shell is made up of aluminium alloy, described cylindrical shell is provided with the buttstrap 2 be made up of timber near tail end, described buttstrap is removably connected by screw and cylindrical shell, buttstrap is provided with the deep-slotted chip breaker 3 contacted with launching crew's shoulder.When launching fire extinguisher bomb, shoulder contacts with deep-slotted chip breaker, in order to hold gun barrel, can carry out fire extinguisher bomb transmitting.The fire-extinguishing shell launcher gun barrel of this structure, in emission process, on the one hand, cylindrical shell is made up of aluminium alloy, buttstrap is made up of timber, lightweight, effectively can save muscle power, on the other hand, contacted with launching crew's shoulder by the deep-slotted chip breaker on buttstrap, carry out support to cylindrical shell to fix, avoid emission process middle cylinder body shake severe and affect fire accuracy, effectively improve launch accuracy.
As the further improvement to technique scheme, described arc cell wall is provided with the air bag cushion 4 mated with deep-slotted chip breaker, air bag cushion and deep-slotted chip breaker are bonded together, and also comprise gas cell 5, described gas cell is communicated with air bag cushion by airsac tube 6, described airsac tube is provided with valve 7.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, described cylinder body outer wall is provided with locating ring 8, described buttstrap is provided with the locating slot 9 mated with locating ring.When being arranged on cylindrical shell through buttstrap, locating ring mates with locating slot, can improve installation effectiveness.
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.
