Special caliper tool cylinder insertion with pairs of cylinder screws, unscrews front cover.
The course of work of the invention:
1) it installs: rotating clockwise locking cylinder, driving the trip on muzzle connector to rotate simultaneously makes trip rotation from rifle
Tool thorax mouth rear end screws out, at this time in the unlocking pit for withstanding on location dimples on muzzle connector in locking cylinder, if rifle
In unlocking condition, the step can be omitted mouth suppressor original state, be inserted into muzzle suppressor from muzzle, the connection on muzzle connector
Set slides into and is matched on muzzle thorax mouth, and slightly rotation muzzle suppressor makes connector sleeve front end positioning pin to notch on positive firearms thorax mouth
And slide into, locking cylinder is rotated counterclockwise, and the pivot protrusion on raised rotation forces trip is driven to rotate trip, its underpart
Circular arc screw-in is stuck in firearms thorax mouth rear end, realizes and muzzle suppressor is connected locking (see Figure 17) and is contained on firearms, this
When locking cylinder the location dimples for withstanding on muzzle connector locking pit in.
2) it dismantles: rotating clockwise locking cylinder, the pivot protrusion on raised rotation forces trip is driven to rotate trip
It is screwed out from firearms thorax mouth rear end, it is real at this time in the unlocking pit for withstanding on the location dimples on muzzle connector of locking cylinder
The solution of existing muzzle suppressor and firearms locks, and muzzle suppressor is pulled to deviate to complete muzzle suppressor from tearing open on firearms from muzzle
It unloads.
3) course of work: being correctly mounted on muzzle suppressor on firearms and lock first, when small arms firing, gunpowder
Explosion combustion gas pushes bullet to fly over muzzle forward along gun barrel and fly into muzzle suppressor and is flown out by centre bore, and powder gas is same thereafter
Sample enters in muzzle suppressor muzzle connector with bullet, and Some gases are gushed from pressure hole is rushed down, and most of combustion gas continuation is led to forward
Regulator hole ejection is crossed, regulator hole can be effectively controlled the time for delaying powder gas to spray and size, and powder gas is sprayed from regulator hole
Enter in muffler body component after out, by rear noise elimination bowl, several middle noise elimination bowls, preceding noise elimination bowl, front cover and outer cylinder in noise elimination body component
(structure is divided by the thin-walled cylinder and outer tube inner wall that are provided with shift frequency decompression hole on bowl of individually eliminating the noise in radial radial two rooms of muffler body that constitute
At) and axial multilayer (being made of the disk b in disk a in rear noise elimination bowl, several middle noise elimination bowls, preceding noise elimination bowl, front cover segmentation)
Two Room MULTILAYER COMPOSITE noise elimination body cavitys, it is radial to constitute in each noise elimination bowl and outer cylinder after powder gas enters in noise elimination body component
Expansion is blocked when by shift frequency decompression hole on noise elimination bowl thin-walled in radial two Room, filtering reduction of speed decompression, sensitive to human ear
The frequency of stimulation is constituted to the insensitive inirritative frequency shift frequency of human ear, axial powder gas by each noise elimination bowl disk, front cover
Axial noise elimination cavity when, powder gas forward with noise elimination bowl disk wall and horn-like rotation external surface collision blocking reflected it is reversed
Counteracting is mutually collided with forward powder gas reduces the decompression of energy reduction of speed, and part powder gas is again from horn-like rotary body aperture
Outflow enters next layer, and powder gas offsets filtering expansion decompression shift frequency through multilayer barrier, when powder gas is from muzzle suppressor
When front cover sprays, the frequency response of powder gas major part frequency is insensitive to human ear not to be stimulated, powder gas velocity pressure substantially drops
It is low, realize the inhibition of noise when to shooting.
Finally, it should be noted that the above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations；Although
