Description

 The invention relates to laser sighting devices, in particular to small arms, using laser guidance systems to hit a target.

 Known small arms systems with dual sighting devices containing a barrel in the body, a front sight (front sight), an aiming bar (rear sight), an aiming laser device including an optical-mechanical device (lens with lenses) that convert the laser beam to spot sizes on targets necessary for visibility by the shooter, a laser emitter with an electronic unit and a power source located in the tube body, a laser beam guidance system attached to the tube and the body when an integral laser device, and elements for fastening and locking the tube on the body of the weapon.

 In this small arms guidance system is installed in the central part of the weapon, between the end of the barrel and the bed in order to minimize the effect of the component of the recoil force on the laser, which ultimately has a significant impact on the results of the shot. Attempts to solve this problem are based on the principle of shifting the aiming device relative to the weapon at the time of the shot using any mechanism that absorbs recoil energy, while the guidance system is mounted on the weapon, located along it so that the laser is above the weapon, parallel to the barrel, without lateral displacement .

 The guidance system freely slides relative to mounting devices mounted on the weapon and dissipates impact energy due to friction between the mounting device and the guidance system. The guidance system is mounted on the barrel using ring holders.

 Ring holders have the ability to slide along the barrel, and on the barrel they are fixed using springs and allow the weapon to move relative to the guidance system and return to its original position after the shot (recoil).

 Thanks to the spring, the backward movement of the weapon is limited, and the recoil energy is absorbed by transferring the impact force from the gun through the ring to the pin supported by the spring [1].

 The disadvantage of this system is that the laser sighting device mounted on the weapon overlaps the line of sight of the mechanical sight of the front sight. In addition, the laser beam guidance system relative to the axis of the barrel of the weapon uses calibration flywheels, which require dimensions and impair the overall dimensions of the weapon, since vertical dimensions increase if the flywheels are located below, or go beyond the dimensions of the weapon, i.e. when the flywheels are located below, the dimensions of the sighting laser device increase upwards and overlap the aiming line of the front sight, and when the flywheels are located on the side, the dimensions increase in width.

 In addition, when the aiming laser device fails, especially in combat conditions, the interchangeability of sighting laser devices from one weapon to another is violated, since it takes time to adjust and fasten it to the weapon.

 All these shortcomings lead to a deterioration in the operational characteristics of small arms, i.e. reduce its effectiveness in combat use.

 The closest in technical essence is a small arms with a double sighting device, containing a barrel in the body and a bracket with two holes, one of which contains the barrel, and the laser sighting device is installed in the second hole of the bracket under the barrel on its muzzle, and the base on the bracket made of elastic material and has two walls for mounting it on the barrel of a weapon [2].

 The disadvantages of this weapon include the fact that the side walls are bent outward when installing the sighting device on the barrel, after which they partially return to their original state, while the walls cover the barrel, holding it tightly, and the base is made of flexible plastic, which allows bending its walls, and from the walls an elastic protrusion extends from the inside, allowing to attach an aiming device.

This technical solution is inconvenient when operating small arms with a double sighting device in temperature conditions from plus 50 ^o C to minus 50 ", since at the indicated temperature conditions of small arms with a double sighting device when firing bursts, the elastic properties of elastic plastic change, which does not allow replace the laser sighting device during the battle, and the elastic protrusion unreliably fixes the laser sighting device on the barrel muzzle, which reduces the usability weapons, the effectiveness of its combat use falls.

 The aim of the invention is to improve the usability of small arms with a double sighting device and increase the effectiveness of its combat use.

 This goal is achieved by the fact that the proposed small arms with dual sighting device contains a barrel in the body and a bracket with two holes, one of which is the barrel, while the laser sighting device is installed in the second hole of the bracket under the barrel on its muzzle, and on the body weapons made emphasis, and between the holes of the bracket made a blind groove, in which through the axis is fixed the latch with the possibility of interaction with your tooth with emphasis on the body of the weapon, and the end surface l of the latch opposite to the tooth is located at an angle to the bottom of the blind groove of the bracket and a blind hole is made in it, in which a spring is installed, in addition, a bracket groove is made in the bracket perpendicular to the blind groove, through which a leash passes, fixed in the hole, additionally made in latch.

 This design of small arms with a double sighting device allows for the assembly and disassembly of the sighting laser device when it is used in all temperature conditions of military use, and increases fixation when firing in bursts.

 In addition, mounting a laser sighting device on the muzzle of the weapon barrel in the form of a monolithic bracket reduces the angle of the bullet for the weapon barrels with the outer surface of the barrel conically tapering from the muzzle, since bending vibrations with a maximum amplitude in the front third of the barrel are excited when fired in the barrel .

 In accordance with this, the bending stiffness of the barrel can only be increased by increasing the diameter of the barrel along the outer diameter in the corresponding section, which ensures the bracket of the laser sighting device mounted on the muzzle of the barrel of the weapon, which increases the effectiveness of its combat use.

 In FIG. 1 shows a general view of a small arms with a double sighting device, which consists of a barrel 1 in the weapon body 2, which under the barrel has a stop 3 and a handle 4, a quick-detachable device made in the form of an arm 5, an aiming laser device 6; the bracket 5 has two holes 7 and 8 for the weapon barrel and an aiming laser device, and a blind groove 9 is made between the holes of the bracket, in which the latch 10 is fixed with the tooth 11, the axis 12 with the possibility of interaction of the tooth 11 with the stop 3, while the end surface 13 of the latch 10, opposite the tooth 11, is located at an angle to the bottom of the blind groove 9 of the bracket 5, and it has a blind hole 14 in which the spring 15 is installed, and a bracket groove 16 is made perpendicular to the blind groove 9, through which the lead passes 17, zak eplenny in the hole 18, further performed in the latch 10.

где
R - наружный радиус ствола в области соответствующей нагрузки;
r - внутренний радиус ствола.In FIG. 2 graphically bending vibrations that are excited in the barrel when fired, where 1 is the barrel, 2 is the muzzle of the barrel, 3 is the point of attachment of the barrel, 4 is the bracket, S is the bending vibrations when fired, B _x is the bending rigidity of the barrel, which equal to E • J _x
Where
E - modulus of elasticity
J _x is the moment of inertia of the area per unit length
In its turn

Where
R is the outer radius of the barrel in the region of the corresponding load;
r is the inner radius of the barrel.

 It can be seen from the graph that the bending stiffness of the barrel can be increased only by increasing the diameter of the barrel, and the bracket mounted on the muzzle of the barrel reduces the angle of departure of the bullet, increases the accuracy of the weapon, as the bending stiffness of the barrel increases.

 The sighting laser device is mounted on the weapon as follows.

 Prior to being placed on a weapon, the laser radiation axis is adjusted using a TXP (cold shooting optical tube), which is installed in the hole 7 of the bracket 5 instead of the barrel of the weapon, then the aligned aiming laser device 6 is mounted on the barrel 1 with the bracket 5 until it stops in the weapon body 2, the leash 17 reduces the spring 15 and the tooth 11 of the retainer 10 leads over the stop 3 of the weapon body 2 under the barrel 1, releasing the leash 17 and the spring 15, the tooth 11 of the retainer 10 comes into contact with the stop 3 of the weapon body 2, fixing the bracket on the weapon.

 Dismantling of an aiming laser device with an arm from a weapon is carried out in the reverse order: the spring 15 is removed by a leash 17, while the tooth 11 of the retainer 10 is rotated on the axis 12 and disengages from the emphasis 3 of the weapon body 2, after which it is removed from the muzzle of the barrel 1 together with bracket.

 Thus, the proposed technical solution improves the usability of small arms with a double sighting device in combat situations, reliably fixes the sighting laser device when firing bursts and operating at minus and plus temperatures, which increases the effectiveness of its combat use.
