Description

The utility model relates to devices for testing or checking sighting devices and can be used to determine the consistency of the axis of sighting devices of 7.62 mm small arms, designed for the 7.62×54R rifle cartridge, with the axis of the bore. A laser cartridge for cold shooting is known from the prior art (Patent RU 147939 U1, published on November 20, 2014), containing a cylindrical body made in the shape of a cartridge body with dimensions corresponding to the caliber of small arms, with a cylindrical laser module placed in it containing a lens and a laser diode, wherein the laser module is made of two parts - a laser diode body and a lens body, coupled with the possibility of sliding; a laser diode driver electrically connected to the laser module via a spring; a battery isolated from the cartridge body and consisting of a set of batteries; a back cover with a power switching device containing a sleeve rigidly fixed in the center of the back cover and made of insulating material, inside of which there is a plunger protruding beyond the surface of the back cover by an amount not exceeding the length of the compression stroke of the spring in contact with the power element; radial threaded holes made in a cylindrical housing in the area of the laser module and located along two circles of the housing at the edges of the laser module, six in number, three holes per circle, the angles between the axes of the holes are 120 degrees; adjusting screws screwed into threaded holes.

The closest in technical essence is the individual set of non-firing control of sighting devices of a 5.45 mm Kalashnikov assault rifle (Patent RU 2788425 C1, published on January 19, 2023], containing a laser cartridge for cold zeroing, including a cylindrical body made in the shape of the cartridge case body with dimensions corresponding to the dimensions of the sleeve of a standard machine cartridge and made with an internal threaded connection on the barrel of the sleeve, with a laser diode driver located in a cylindrical body of a cylindrical laser module containing a lens and a laser diode, electrically connected to the battery by means of a spring, a back cover with a switching device power supply, containing a sleeve rigidly fixed in the center of the back cover and made of insulating material, inside of which there is a plunger protruding beyond the surface of the back cover by an amount not exceeding the compression stroke of the spring, in contact with the battery, radial threaded holes made in a cylindrical body in the area of the laser module and located along two circles of the housing at the edges of the laser module, six in number, three holes per circle, with angles between the axes of the holes being 120 degrees, adjusting screws screwed into threaded holes; a power supply consisting of a set of batteries; device for limiting the deflection of the laser beam, made in the form of a nozzle with a calibrated hole diameter equal to 0.001 m, on the outer side of which there is an external threaded connection with dimensions corresponding to the internal threaded connection along the entire length of the sleeve muzzle, an emphasis on the muzzle of the machine gun, made with a diameter exceeding weapon caliber, barrel bushing with a mate corresponding to the caliber of the machine gun with one or more sealing rings made of polymer materials placed in the grooves of the barrel bushing.

During the production of a laser cartridge for cold shooting 7.62×54R, it was established that the use of patented technical solutions of the prototype and its analogues is impossible, since in some samples of small arms 7.62 mm caliber (for example: 7.62 mm sniper rifle Dragunov (SVD, Index GRAU - 6 V1), 7.62-mm Kalashnikov infantry machine gun (PKP or "Pecheneg", Index GRAU - 6P41)), instead of the muzzle brake of the compensator, non-removable flash suppressors are installed, which prevents the installation of a device for limiting the deflection of a laser beam with sides of the muzzle. In addition, it has been established that the use of a laser cartridge made without a bullet simulator, like an analogue, in the form of a standard cartridge case, as well as without a device for limiting the deflection of the laser beam, is impossible, due to the lack of centering of the laser cartridge in the elliptical chamber of the barrel bore - technical solution manufacturers of small arms, necessary for reliable chambering of cartridges into the barrel. At the same time, it was also not possible to send a cartridge into the chamber with the device for limiting the deflection of the laser beam not removed due to the presence of a stop in the muzzle of the machine gun, made with a diameter exceeding the caliber of the weapon.

Technical result.

The claimed laser cartridge for cold shooting 7.62×54R will ensure: preservation of the technical capabilities of the prototype;

expanding the scope of application of laser cartridges - the possibility of use in barrel systems with non-removable flash suppressors.

The specified technical result is achieved by using, when checking the consistency of the axis of sighting devices of 7.62 mm small arms, designed for the 7.62×54R rifle cartridge, with the axis of the barrel bore, a device containing a laser cartridge for cold sighting, made with an internal threaded connection on the barrel of the cartridge case with installed batteries and a non-removable modernized nozzle for limiting the deflection of the laser beam, with a calibrated hole diameter equal to 0.001 m, made in the part opposite from the cartridge body, and external overall dimensions corresponding to the dimensions of the 7.62×54R cartridge bullet, on the outer on the side of which there is an external threaded connection for mounting to the cylindrical body of a laser cartridge for cold shooting, with one or more sealing rings made of polymer materials installed in the grooves of the device in places where the diameter of the nozzle for limiting the deflection of the laser beam corresponds to the diameter of the bore of the small arms.

Laser cartridge for cold zeroing 7.62×54R is a device containing a cylindrical body of a laser cartridge for cold zeroing with a cylindrical laser module, battery, back cover with a power switch and adjusting screws 1 placed in the cylindrical body of a cylindrical laser module, made with an internal threaded connection on the barrel barrel 2 there is a nozzle for limiting the deflection of the laser beam 3 with a calibrated hole diameter equal to 0.001 m 4 and external overall dimensions corresponding to the dimensions of the 7.62×54R cartridge bullet, on the outer side of which there is an external threaded connection for mounting to the cylindrical body of the laser cartridge for cold zeroing 5, with one or more sealing rings made of polymeric materials 6, installed in the nozzle grooves in places where the outer diameter of the nozzle corresponds to limit the deflection of the laser beam with the diameter of the bore of the small arms 7.

A laser cartridge for cold zeroing of small arms designed for the 7.62×54R rifle cartridge works as follows. A cylindrical body of a laser cartridge for cold zeroing with a cylindrical laser module, a battery, a back cover with a power switch device and adjusting screws 1 housed in a cylindrical body, made with an internal threaded connection on the sleeve neck 2, with a nozzle for limiting the deflection of the laser beam 3, with a diameter a calibrated hole equal to 0.001 m 4, and external overall dimensions corresponding to the dimensions of the 7.62×54R cartridge bullet, on the outer side of which there is an external threaded connection for mounting to the cylindrical body of the laser cartridge 5, with one or more sealing rings made of polymeric materials 6 , installed in the nozzle grooves in places where the outer diameter of the nozzle corresponds to limit the deflection of the laser beam with the diameter of the small arms barrel bore 7 is installed in the magazine and sent by the machine gunner (sniper) into the chamber of the small arms bore. In this case, sealing rings made of polymeric materials 6 installed in the grooves of the nozzle in places where the outer diameter of the nozzle for limiting the deflection of the laser beam corresponds with the diameter of the bore of the small arms 7 centers the non-removable nozzle for limiting the deflection of the laser beam 3, with a diameter of the calibrated hole equal to 0.001 m 4 in the rifling bore of small arms. If necessary, it is possible to install a laser cartridge for cold shooting into the chamber manually, without using a magazine.

After which, the machine gunner (sniper) sets the rear sight of the mechanical sight in position - according to the distance to the target (selects the aiming mark of an optical or night sight) and determines the aiming point on the target (remote point, target), so that the point of impact is the projection of the laser beam a laser cartridge for cold shooting, running along a non-removable nozzle limiting the deflection of the laser beam 3, with a calibrated hole diameter equal to 0.001 m 4, located in the part of the nozzle opposite to the cylindrical body of the cartridge, was in the center of the target. If necessary, sighting devices are adjusted. The laser beam, passing along the nozzle for limiting the deflection of the laser beam 3, is calibrated by a calibration hole measuring 0.001 m 4, located in the center of the non-removable nozzle for limiting the deflection of the laser beam 3, installed in the bore of the weapon, produces an accurate projection of the laser beam on the target. At the same time, the use of a non-removable nozzle for limiting the deflection of the laser beam 3, centered by sealing rings made of polymeric materials 6 in the rifling of the barrel bore, will maintain high accuracy when checking the consistency of the axis of the weapon's sighting devices with the axis of the barrel bore, due to centering and limiting the deflection of the laser beam. If the laser cartridge for cold shooting is in good condition and the laser beam does not pass through the calibration hole 4, the non-removable nozzle for limiting the deflection of the laser beam 3, the cylindrical laser module is calibrated relative to the calibration hole 4 using the existing calibration screws of the laser module.
