Description
Technical field
The invention belongs to firearms art, and in particular to a kind of spiral revolution rigid locking mechanism of pistol.
Background technology
At present, pistol closedown mode mainly has free style, three kinds of modes of semi-free formula and rigid locking in the world, for big
For power pistol cartridge using rigid locking mode (such as Ge Luoke, Browning, John Moses, Xi Ge-that continues, 54 formulas, Coalter M1911,
The pistols such as Beretta 92F).It is most of to use Browning, John Moses locking (i.e. gun barrel swing type) mode (such as 54 in rigid locking mode
The early productions such as formula pistol, M1911 pistols, Browning, John Moses high power pistol) or improvement after Browning, John Moses closedown mode (such as Ge Luoke
Pistol, Xi Ge-continue your pistol, USP pistols of HK companies etc.), the closedown mode is simple in construction, but uses rear latch surfaces for a long time
Precise decreasing can be caused after abrasion, the factor such as parts discontinuity, asymmetric when there is open and close lock, automatic parts use the longevity
Life is affected, and uses pistol (such as Beretta 92F pistols) structure of gib swing type rigid locking more complicated, moving parts
Parts intensity is limited less than Browning, John Moses formula closedown mode by structure.
The content of the invention
In order to solve the above problems, the present invention provides a kind of spiral revolution rigid locking mechanism of pistol, mainly in gunlock

Helicla flute, the top of the gunlock offers the slot to make way of the spiral revolution boss on resigning gun barrel, and the slot to make way is located at described
First interval screw closure supports the rear of tooth；Helicla flute that spiral revolution boss on gun barrel is stretched out on connecting seat and through rifle
Slot to make way on machine is interior and drive gun barrel rotation can be moved in helicla flute；
During locking, the second interval screw closure support tooth on the gun barrel and the first interval screw closure branch on gunlock
Support tooth to fasten, the second interval connection valve tooth on the first interval connection valve tooth and gun barrel sleeve on gunlock is fastened, the spiral shell on gun barrel
The helicla flute that cycle turns on boss contact connection seat is anterior；
After transmitting, overall recoil under the gunpowder energy effect of gunlock, gun barrel, gun barrel sleeve after bullet percussion moves one section
The helicla flute rear portion on spiral revolution boss contact connection seat on rear gun barrel, the helicoid of helicla flute forces gun barrel rotation
Turn, the second interval screw closure support tooth on gun barrel is disengaged with the first interval screw closure support tooth unblock on gunlock, rifle
Machine and gun barrel sleeve continue recoil motion under powder gas dump energy and effect of inertia, complete ejection, overwhelm hammer, enter to push away again
Spring into after the actions such as thorax, gunlock and gun barrel sleeve are entered again under kicker effect, after gunlock contact gun barrel, continuing to enter again
By the anterior helicoid effect counter force gun barrel revolution of helicla flute on connection seat in journey, the second interval spiral on gun barrel is closed
Lock support tooth is fastened with the first interval screw closure support tooth on gunlock and locked.
Further, the connecting seat bottom is provided with before the connecting hole for being used for connecting connecting seat and gun bottom hold, the connecting seat
