Abstract
The utility model provides a kind of air gun with silencing function, comprise gun barrel, described gun barrel outside is provided with noise reduction base, gun barrel is inserted on described noise reduction base right side, noise reduction base left side is provided with cylindrical bore, in described noise reduction base endoporus, place a cylindrical shape sound-absorbing pipe made from sound-absorbing material, described sound-absorbing pipe is provided with trickle aperture; Port at noise reduction base is provided with end cap.The utlity model has good noise reduction, owing to having adopted the sound-absorbing pipe of being made by soft sound-absorbing material, its sound-absorbing pipe has good extensibility, to being installed in noise reduction seat, the dimensional requirement of the cylindrical bore of silencing means greatly reduces, improved the first-time qualification rate of noise reduction base injection moulding, and installation is more convenient, cost is relatively cheap.
Description
Technical field
The utility model relates to air gun, particularly with the air gun of silencing function.
Background technology
Shooting firearms with muffler can be subdued shot noise in shooting course, and the repeatedly expansion that existing muffler adopts is multistage noise-damping bowl by gas comes consumed energy to carry out classification noise reduction, and structure is more complicated, and cost is higher.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, with low cost and have an air gun of good silencing function.
The utility model, comprise gun barrel, described gun barrel outside is provided with noise reduction base, gun barrel is inserted on described noise reduction base right side, noise reduction base left side is provided with cylindrical bore, in described noise reduction base endoporus, place a cylindrical shape sound-absorbing pipe made from sound-absorbing material, described sound-absorbing pipe is provided with trickle aperture; Port at noise reduction base is provided with end cap.
As further improvement of the present utility model, described gun barrel is provided with three parallel grooves, and then the independent injection molded of noise reduction base is press-fitted noise reduction base and gun barrel to be integral.
Coming consumed energy to carry out classification noise reducing muffle with the general repeatedly expansion that is multistage noise-damping bowl by gas adopting of existing muffler compares, the utility model has adopted the single sound-absorbing pipe of being made by the soft sound-absorbing material of countless trickle apertures to carry out single-stage noise reduction, and its main feature is as follows:
1, muffler is in the past generally adopt mechanical noise reduction and take multistage progressively noise reduction to reach final noise reduction, this muffler has adopted by the soft quieter material of countless trickle apertures and has made single sound-absorbing pipe, after its operation principle high pressure gas cognition after bullet shooting enters the trickle aperture of sound-absorbing pipe, by making the heating of sound-absorbing pipe, catabiotic method reaches final noise reduction object.
2, have good noise reduction, by related experiment comparison, actual noise reduction is greater than 5 decibels.
3, owing to having adopted the sound-absorbing pipe of being made by soft sound-absorbing material, its sound-absorbing pipe has good extensibility, to the dimensional requirement of the cylindrical bore of silencing means is installed in noise reduction seat, greatly reduces, and has improved the first-time qualification rate of noise reduction base injection moulding, and installation is more convenient, cost is relatively cheap.
Accompanying drawing explanation
Fig. 1 is the longitudinal section schematic diagram of the utility model silencing function structure.
Fig. 2 is the scheme of installation of the utility model silencing function structure.
1. gun barrel 2. noise reduction base 3. sound-absorbing pipe 4. end caps.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
The utility model, comprise gun barrel 1, described gun barrel 1 outside is provided with noise reduction base 2, gun barrel 1 is inserted on described noise reduction base 2 right sides, noise reduction base 2 left sides are provided with cylindrical bore, in described noise reduction base endoporus, place a cylindrical shape sound-absorbing pipe 3 made from sound-absorbing material, described sound-absorbing pipe is provided with trickle aperture; Port at noise reduction base is provided with end cap 4.
In Fig. 1, the first independent injection molded of noise reduction base 2, is then combined into one by being press-fitted form with gun barrel 1, and wherein gun barrel middle-end has been cut three end grooves, has limited and has been press-fitted the free degree that rear noise reduction base 2 moves forward and backward.Meanwhile, because of the press-fit of noise reduction base 2 employing principle of expanding with heat and contracting with cold and gun barrel, so also limited the longitudinally rotation of axis of noise reduction base 2.
In noise reduction base 2, pack a sound-absorbing pipe 3 made from sound-absorbing material into, finally with end cap 4 sealings.Sound-absorbing material is the quieter material that similar sponge etc. has trickle aperture.
When being press-fitted noise reduction base, the utility model utilizes the principle of expanding with heat and contract with cold, when after noise reduction base injection molded, body temperature is higher, be press-fitted into gun barrel, noise reduction base can be press-fitted and put in place more smoothly, until hush pipe seat body temperature is cold go to normal temperature after because of its thermal deformation coefficient make it more greatly with become coordinating of gun barrel more tight, and then noise reduction base is increased greatly to the enclasping force of gun barrel, the gun barrel cover having caused because of kick while effectively having prevented normal shooting moves forward and backward and radial rotating.
Claims (2)
1. with the air gun of silencing function, comprise gun barrel, it is characterized in that described gun barrel outside is provided with noise reduction base, gun barrel is inserted on described noise reduction base right side, noise reduction base left side is provided with cylindrical bore, in described noise reduction base endoporus, place a cylindrical shape sound-absorbing pipe made from sound-absorbing material, described sound-absorbing pipe is provided with trickle aperture; Port at noise reduction base is provided with end cap.
2. the air gun with silencing function according to claim 1, is characterized in that being evenly provided with three parallel grooves on described gun barrel.
