Abstract
The invention relates to a gun, in particular to a gun barrel capable of improving firing precision of the gun. Vertical small holes are formed above the axial line at the front part of the gun barrel, so that the defect of muzzle jump during the design is overcome. The vertical small holes are formed above the axial line at the front end of the gun barrel. A conical groove is formed on the inner wall of the gun barrel and communicated with the bottom ends of the small holes, and the upper end of each small hole is flared for forming a V-shaped port section. The number of the vertical small holes is two in a best way. The distance from the small hole at the most front end to a muzzle is within 5mm, and the distance from the other small hole to the small hole at the most front end is also within 5mm. The gun barrel disclosed by the invention can enable the gun barrel to produce downward motion trend force because reaction force formed by injection of ultra-high pressure gas flow acts above the gun barrel, offset muzzle jump force and greatly improve the target firing precision.
Description
Technical field:
The present invention relates to a kind of firearms, be specifically related to a kind of gun barrel that improves the small arms firing precision.
Background technology:
During the rifle shooting, the power of moving back of staying of generation produces tilting moment to the rifle height to the firing area, promptly jumps on the muzzle.Because live wire moves back line and does not overlap with staying, when particularly overcoming long fixed fire or continuous fire muzzle on jump over and send out significantly.
Under many circumstances, need carry out the test of target test specimen of shooting certification test and the multiple material of firearms to product.When the target specimen test, often very high requirement is proposed fire accuracy (target point of impact).For example: in the armored vehicle welding test, bullet needs 125 meters weld seam and heat affected areas thereof that distance is last in the gunslinging, promptly is the target of center φ 40mm circular diameter with the weld seam, precision be equivalent to people's chest silhouette 10 anchor rings long-pending 1/5.In addition, the standard rifle is contained in when shooting is examined on the armored vehicle, and required precisions such as fixed fire, interrupted fire, long fixed fire are arranged.Above-mentioned example crack shot is difficult to accomplish.
Summary of the invention:
The present invention is through offering vertical aperture, the defective of having jumped on the muzzle when having overcome design above the anterior axis of gun body pipe.
The present invention is realized by following technical scheme:
A kind of gun barrel that improves the small arms firing precision has vertical aperture above gun body pipe front end axis.
Have cone tank on the gun body pipe inwall, be communicated with the aperture bottom, the aperture upper end extends out, and becomes V-type mouth cross section.
Vertical aperture is preferably 2.
Foremost aperture apart from muzzle distance within 5mm, another aperture apart from aperture foremost also within 5mm.
The present invention utilizes the super-pressure air-flow to spray the reaction force that forms, and acts on the gun barrel top, makes barrel produce downward movement tendency power, offsets the power of jumping on the muzzle, has greatly improved the goal precision.
Description of drawings:
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the A-A view of Fig. 1.
The specific embodiment:
Shown in Fig. 1-2; The present invention is a kind of gun barrel that improves the small arms firing precision, in order to improve the small arms firing precision, above gun body pipe 1 front end axis, has vertical aperture 2; The super-pressure air-flow sprays the reaction force that forms during like this with regard to shooting capable of using; Act on the gun barrel top, make barrel produce downward movement tendency power, offset the power of jumping on the muzzle.Improve the goal precision.In order further to improve fire accuracy, can have 2 vertical aperture 2, like this, the super-pressure air-flow of first aperture provides most reaction force, and the remaining reaction force of second aperture generation is further offset moving upward of gun barrel.In addition, jump in order to offset on the gun barrel to greatest extent, aperture is good more the closer to muzzle foremost, and its moment that instead goes up jumping is just big more like this, and generally speaking, it should be within 5mm apart from the muzzle distance.As 2 apertures are set, the 2nd aperture also should be within 5mm apart from first aperture.
Consider that bullet moves, rotates in gun body pipe 1; Pushed by rifling, bullet is during through 2 apertures 2, and the radial friction force direction reply that acts on the bullet is claimed; So on gun body pipe 1 inwall, have cone tank 3; Be communicated with aperture 2 bottoms, form gather qi together balance conical ring, avoid out aperture to influence the bullet trajectory.
In order further to promote the pressure of the super-pressure air-flow of aperture 2 to gun body pipe 1, aperture 2 upper ends are extended out, form V-type mouth cross section 4.
Claims (4)
1. the gun barrel that can improve the small arms firing precision is characterized in that: above gun body pipe front end axis, have vertical aperture.
2. a kind of gun barrel that improves the small arms firing precision according to claim 1 is characterized in that: have cone tank on the gun body pipe inwall, be communicated with the aperture bottom, the aperture upper end extends out, and becomes V-type mouth cross section.
3. a kind of gun barrel that improves the small arms firing precision according to claim 1 and 2 is characterized in that: vertical aperture is 2.
4. a kind of gun barrel that improves the small arms firing precision according to claim 3 is characterized in that: foremost aperture apart from muzzle distance within 5mm, another aperture apart from aperture foremost also within 5mm.
