Description

The rifle prover

Technical field

The utility model belongs to the firearms field, specifically is the calibration instrument that is used for firearms.

Background technology

Before daily target practice training or ball firing, because artificial or natural reason, the foresight of rifle can be become flexible, and the operator needs in advance rifle to be calibrated.When target range was hundred meters integers, according to the corresponding sight leaf graduation of this range setting, aiming point was selected in impact point.When as automatic rifle the target of 100m distance being shot, decide rear sight and be " 1 ", operator's run-home point is shot, if the drop point of bullet is not on impact point, be that drop point has deviation with impact point on distance and bearing, need foresight is adjusted, and then shooting.The repeated multiple times with actual conditions, on impact point, promptly this rifle is calibrated successfully up to the bullet drop point.

There is following shortcoming in this kind to the calibration process of rifle:

1. many times shooting is to the waste of ammunition;

2. many times shooting increases school rifle link, elongates the school rifle time, reduces school rifle efficient;

3. need the place of specialty, limited space is big.

The utility model content

At the problem of above-mentioned existence, the utility model discloses a kind of rifle prover, mainly form by light source, housing, optical path body and optical path passage.Inside one end of described housing is equipped with light source, and the other end is equipped with the optical path body, and there is the optical path passage optical path body inside, and described optical path passage connects the optical path body.

Calibrating principle of the present utility model: the calibration of traditional preshot, need eyes, foresight and impact point sight alignment, generally come foresight is adjusted by the drop point of live shell rehearsal neutron bomb and the deviation of impact point.Adjusted foresight promptly remains on the sight line with eyes, impact point.If set another point on the sight line between foresight and the impact point, this more close human eye of point and easy identification more just keeps eyes, foresight and this sight alignment when so only needing calibration just can omit the link that impact point and live shell are calibrated is set.So need two preconditions, the one, this point will be on the sight line of having calibrated, and the secondth, need to determine the accurate position of this point.So, before dispatching from the factory, the rifle prover just need setup parameter to make this on the good sight line of calibration, in the actual alignment training after dispatching from the factory, also need the training court is provided with requirement.The rifle prover that the utility model provides be fixedly connected on the gun barrel termination under, the light beam of the light emitted that it is inner will intersect with the good sight line of calibration by the optical path passage, if can determine the angle of light beam and sight line, this intersection point just can be determined.In the utility model, promptly need to determine the angle of prover optical path channel centerline and sight line.But for the manufacture process of rifle prover, what need determine is the angle of prover optical path channel centerline and prover center line.In shooting, the rear sight of rifle and sighting angle are fixed value, and the angle of gun barrel center line and sight line is a sighting angle, and the prover center line in the utility model is parallel with the gun barrel center line, so the angle of prover center line and sight line equals sighting angle.Like this, in the triangle that prover center line, prover optical path channel centerline and sight line are formed, following equation is arranged:

The angle that the angle of prover optical path channel centerline and prover center line equals prover optical path channel centerline and sight line deducts the angle of prover center line and sight line.

In theory, by the light beam of prover optical path channel centerline can be random on the sight line between foresight and the impact point, move, if a panel is set on sight line, light beam will have luminous point thereon, luminous point also is positioned on the sight line certainly.At this moment, people's naked eyes have relation to accurate identification and two factors of this luminous point: one is the size of luminous point, and one is the distance of human eye and luminous point.When adopting laser beam, its beam diameter between 5mm-10mm, the preferable identification distance of people's naked eyes is between 5m-20m.Like this, light beam is in the moving range of luminous point on the sight line should the 5m-20m before human eye.Next, just need to determine the effective range of prover optical path channel centerline and prover center line angle.

Prover optical path channel centerline and prover center line angle have following calculation procedure.

If the angle of prover optical path channel centerline and prover center line is angle a, the angle of rifle prover center line and sight line is angle b, and the angle of optical path channel centerline and sight line is angle c, and the angle of gun barrel center line and sight line is angle d.

Sight line, optical path channel centerline and rifle prover center line have constituted triangle ABC, wherein, and a=angle, angle c-angle b.The center line of rifle prover is parallel with the gun barrel center line, b=angle, angle d.Angle d is a sighting angle, and when rear sight was determined, sighting angle had definite value.

The light source point of rifle prover has a vertical line to sight line, and this vertical line, sight line and optical path channel centerline have constituted right angled triangle ACO, wherein, and tan (c)=OA/OC.

OA approximate gun barrel diameter and rifle prover radius and, general gun barrel diameter is between the 5mm-10mm, rifle prover diameter is between the 5mm-20mm, OA is promptly between 7.5mm-20mm.

OC is armed operator's the eyes and the distance of light beam luminous point on sight line, promptly described preferable identification distance, this distance at 5m between the 20m.But rifle prover light source point, human eye and gun barrel port distance for the identification distance is too near, is not enough to influence calibration effect, can think to be a point.

When rear sight is " 1 ", sighting angle is 8 ', OA is between 7.5mm-20mm, when effectively sighting distance OC is between 5m-20m:

A=angle, angle c-angle b;

B=angle, angle d=sighting angle=8 ';

tan(c)＝OA/OC＝(7.5mm-20mm)/(5m-20m)；

When OA gets maximum, OA=20mm; OC gets minimum of a value, OC=5000mm, angle c=14 ';

A=angle, angle c-angle b=14 '-8 '=6 ';

When OA gets minimum of a value, OA=7.5mm, OC gets maximum, OC=20000mm, angle c=1.2 ';

A=angle, angle c-angle b=1.2-' 8 '=-6.8 '.

Prover optical path channel centerline and prover center line angle a 6 ' and-6.8 ' between, promptly angle a and optical path passage are in rifle prover center line is first and four-quadrant of transverse axis and the coordinate system that constitutes with the longitudinal axis that passes light emitted point.

Described lower housing portion close to sources place also has locating hole, and this hole connects housing.When training was practiced shooting, after the light source in the rifle prover penetrated from the locating hole of housing, promptly certain that can fall earthward a bit maintained static for a long time if desired and practises aiming, as long as keep the drop point on ground motionless, just can arrive the effect of training.As the coach, just can whether move monitor operator's operation attitude and its ability is investigated by hot spot.

Below by the drawings and specific embodiments this utility model is described further.
