Abstract
The application provides a kind of compact self extending muffler, including obstructing storehouse (1), rear end extends storehouse sleeve (2) and front end extension storehouse sleeve (3), it is characterized in that, the rear end extension storehouse sleeve (2) and front end extension storehouse sleeve (3) are hollow sleeve, barrier storehouse (1) is set in rear end extension storehouse sleeve (2) and front end extension storehouse sleeve (3), the purpose of this utility model is to provide a kind of all applicable mufflers of all types of gun, the technical issues of solving traditional firearm suppressor high processing costs and complex process, it can solve the problems, such as that existing muffler is excessively thick or long excessively heavy in the case where not changing present fire accuracy again.
Description
Technical field
The utility model is related to firearms noise reduction field, especially a kind of compact self extending muffler.
Background technology
The design structure of standard muffler generally extends storehouse and various forms is added to obstruct storehouse.Group bounces off shooting mouth, promotes
The pressure high temperature hot gas of bullet enters extension storehouse in order, subsequently enters barrier storehouse.Muffler is generally reached by depressurizing cooling
To elimination/reduction muzzle sound.
Extension storehouse provides extension to high pressure-temperature gunpowder and reaches effect of easing stress, and barrier storehouse is prevented or led by multilayer baffle
Pressure high temperature hot gas is flowed to reduce the high temperature and high pressure gas for spraying muzzle to reach cooling-down effect (noise reduction), and two kinds of positions in storehouse close together
Make decompression cooling to reduce shot.
According to The Ideal-Gas Equation pV=nRT
Muffler central principle is decompression (p), and the premise of decompression is exactly to reduce energy (n) and reduce temperature (T) while increasing
It is equivalent to reduce sound while adding capacity (V) to reduce muzzle pop-up gun pressure power (p).And reducing energy (n) can only pass through
Change bullet model or is reached using modes such as decoction bullets and muffler itself is unrelated.
Temperature (T) is reduced, can be reached by the barrier storehouse of muffler, water filling or glue etc. can also be added in muffler
To realize.Secondly increase capacity (V) is added or overstriking extends storehouse.
The overall length of muffler is expansion tank+barrier storehouse, it is desirable to which the erasure effect reached, common practices are to lengthen to add
Thick expansion tank lengthens barrier storehouse.But adding extension storehouse certainly will bring silencer length long, and overstriking muffler
Way can hinder to aim at, amplified so extension storehouse can only be lengthened.But long muffler uses meeting in small space
It makes troubles, too short small silencer is again without good erasure effect.
Utility model content
To overcome existing defect, the utility model proposes a kind of compact self extending mufflers.
A kind of compact self extending muffler, including barrier storehouse, rear end extension storehouse sleeve and front end extend storehouse sleeve, described
It is hollow sleeve that rear end, which extends storehouse sleeve and front end extension storehouse sleeve, and barrier storehouse is set to rear end extension storehouse sleeve and front end extension
In the sleeve of storehouse, wherein reserve preview chamber with rear end in rear end extension storehouse sleeve in barrier storehouse rear end.
Wherein, resetting spring is set in rear end extension storehouse sleeve wall, and the resetting spring end connects with barrier storehouse end
It connects.
Wherein, fin shape screw thread is arranged in the rear end extension storehouse sleeve and front end extension storehouse sleeve outer layer.
Wherein, setting cooling cabin in the front end extension storehouse sleeve wall.
Wherein, cushioning piece is arranged in the rear end extension storehouse barrel forward end.
Optionally, gelatin is set in the cooling cabin.
Optionally, the material of the cushioning piece is rubber.
The mesh of the utility model be by will extend storehouse be designed to it is telescopic, when not emission bullet, obstruct storehouse
It is accommodated in completely in extension storehouse, when fired, high pressure gas enters preview storehouse, pushes barrier storehouse to advance up to extension by expanding
Storehouse is fully deployed to reach effect of easing stress, and after pressure reduction, barrier storehouse will obstruct storehouse by external springs and store back extension again
Silencer length is reduced in storehouse.
Double-layer sleeve structure can also be effectively heat-insulated simultaneously, prevents muffler end from scalding user.
Description of the drawings
Fig. 1 is compact self extending muffler schematic diagram.
Fig. 2 is compact self extending muffler operating diagram.
Specific implementation mode
In the following with reference to the drawings and specific embodiments to a kind of compact self extending muffler progress provided by the utility model
Detailed description.
Fig. 1 and Fig. 2 shows a kind of, compact self extending mufflers, including barrier storehouse 1, rear end extension storehouse sleeve 2 and front end
Storehouse sleeve 3 is extended, the rear end extension storehouse sleeve 2 and front end extension storehouse sleeve 3 are hollow sleeve, and barrier storehouse 1 is set to rear end
It extends in storehouse sleeve 2 and front end extension storehouse sleeve 3, wherein barrier 1 rear end of storehouse and rear end in rear end extension storehouse sleeve 2 are reserved pre-
Open up chamber 7.Double-layer sleeve structure can also be effectively heat-insulated, prevents muffler end from scalding user.
Rear end, which extends, is arranged resetting spring 4 in 2 barrel of storehouse sleeve, 4 end of the resetting spring connects with barrier 1 end of storehouse
It connects.
Rear end extends storehouse sleeve 2 and fin shape screw thread is arranged in front end extension 3 sleeve outer layer of storehouse sleeve.Heat dissipation effect can be improved
Fruit further increases muffler erasure effect.
Front end extends setting cooling cabin in 3 barrel of storehouse sleeve.
Rear end extends 2 front end of storehouse sleeve and cushioning piece 5 is arranged.
Gelatin is arranged in cabin in cooling.
The material of cushioning piece 5 is rubber.
Rear end extends 2 end of storehouse sleeve and is mounted on muzzle 6, and when not emission bullet, barrier storehouse 1 is accommodated in completely
It extends in storehouse, when fired, high pressure gas enters preview storehouse 7, pushes barrier storehouse 1 to advance to extension storehouse by expansion and is fully deployed
Reach effect of easing stress, (shooting is completed) after pressure reduction, barrier storehouse 1 will obstruct storehouse 1 by resetting spring 4 and store back expansion again
Silencer length is reduced in exhibition storehouse.
Self extending formula muffler can reduce muffler total length while not weakening muffler effect and be up to 50%.
Volume also can accordingly reduce.
The purpose of this utility model is to provide a kind of all applicable mufflers of all types of gun, that is, solve traditional firearms
The technical issues of muffler high processing costs and complex process, and existing disappear can be made in the case where not changing present fire accuracy
Sound device is excessively thick or long excessively bulky present situation is changed.Improve various gun street fighting, night fighting, fight-terrorism warfare occasion work
War efficiency, more supports interior, the small spaces operation such as car to meet the mission requirements of special force and frontier policeman special policeman army.
Finally it should be noted that above example only to the technical solution of the utility model is described rather than to this technology
Method is limited, and the utility model can above extend to other modifications, variation, application and embodiment in application, and because
This thinks all such modification, variation, application, embodiments all within the scope of the spirit or teaching of the utility model.
