Technical Field

The invention belongs to the field of gun calibration, and particularly relates to a safety type direct-injection gun target calibration mirror.

Background

Existing weapon platforms, such as airplanes, tanks, guns, etc., are often equipped with fire control radars. These master guns equipped with a fire control radar often require their target calibration during use so that the axis of the gun coincides with the center of the cross target plane of the fire control radar. When in target correction, the fire control radar of the gun is firstly aimed at a certain star point in the sky, so that the star point falls on the center of the cross target surface of the fire control radar, then the inserting rod of the target correcting mirror is inserted into the gun barrel of the gun through the gun muzzle, the target correcting mirror is coincided with the mechanical shaft of the gun barrel, and then the star point is coincided with the center of the cross division image in the target correcting mirror by adjusting the deviation angle of the axis of the gun. This is the working principle of the general borescope. In addition, direct firing mirrors are also used for direct firing tests of ammunition and fuze on targets. The field test environment is severe and the test amount is large, so that the gun-shooter often happens that the gun-shooter forgets to take off the gun-shooter from the mouth of the gun barrel after using the gun-shooter to aim, and consequently the gun-shooter is blocked in the gun-shooter to cause the gun-shooter to explode.

Disclosure of Invention

The invention aims to provide a safe direct-firing target correcting mirror for guns, so that the safety during target correcting is improved.

The technical solution for realizing the purpose of the invention is as follows:

a safe gun direct shooting target correcting mirror comprises an optical mirror tube, an inserted link, a signal flag device, a visibility ring, a hand wheel and a water level;

the outer wall of the inserted rod, which is close to the end of the optical lens tube, is matched with the bore of the muzzle through a bulge with a bullet belt structure; the inserted bar end is provided with a pit, and the diameter of the pit is larger than that of the head of the projectile.

Compared with the prior art, the invention has the following remarkable advantages:

(1) the matching part of the inserted rod of the target correcting lens and the inner bore of the barrel is provided with a bulge with a bullet belt structure, and the bulge is matched with the inner bore of the opening part of the barrel, so that 'air-tight' is facilitated, and the target correcting lens can be quickly pushed out of the bore by a moving projectile; meanwhile, the end of the inserted rod of the target correcting lens is provided with a pit which is larger than the head of a matched projectile (fuse), so that the radial expansion of the target correcting lens when the projectile impacts the target correcting lens can be prevented from extruding and expanding the target correcting lens in a chamber, and the explosion accident of the chamber is avoided.

(2) The boresight is made of high-strength light material, so that when the bullet impacts the boresight, the boresight can be quickly knocked out of the bore.

Detailed Description

The invention is further described with reference to the following figures and embodiments.

The invention relates to a safe direct shooting and target correcting lens for a gun, which comprises an optical lens tube 1, an inserted link 2, a signal flag device 3, a visibility ring 4, a hand wheel 5 and a water level 6; the optical lens tube 1 and the inserted rod 2 are coaxially fixed; a signal flag device 3 and a hand wheel 5 are arranged on the optical lens tube 1, and a visibility ring 4 is arranged on the hand wheel 5; the water level 6 is fixed on the optical lens tube 1; the above-mentioned techniques are prior art, not improvement of the present invention; the outer wall of the inserted link 2 close to the end of the optical lens tube 1 is matched with the bore of the muzzle through the bulge 21 with the elastic band structure, which is beneficial to 'air-tight'. The bulge 21 and the bore at the opening of the barrel adopt interference fit, and the inserted link 2 is pressed in the inserted link groove due to the interference fit, so that the stability of the target correcting lens after being inserted into the bore is ensured, and the 'gas stopping' is also facilitated, so that the target correcting lens can be quickly pushed out from the bore by a moving projectile. Meanwhile, the end of the inserted rod 2 is provided with a concave 22, the concave 22 is larger than the head of a matched projectile (fuze), and the inserted rod 2 can be prevented from expanding radially to extrude and expand the inserted rod in a chamber when the projectile impacts a target correcting mirror.

Furthermore, a rubber gasket 8 is arranged on the outer part of the insertion rod 2 close to the end of the optical lens tube 1 to prevent the insertion rod 2 from colliding with the bore hole when being inserted into the bore.

Furthermore, the optical lens tube 1 and the insertion rod 2 are both made of high-strength light materials, such as aluminum alloy, composite materials, high-strength plastics, magnesium-lithium alloy and the like, and when a moving projectile collides with the target calibration lens, the target calibration lens can be quickly knocked out of the bore.

The optical lens tube 1 is provided with an objective lens, a prism, a reticle and an ocular lens. The light rays emitted from the target plate are imaged on the plane of the division plate through the objective lens and the prism. When the target plate is observed from the ocular lens, the magnified target plate image and the division of the reticle can be seen clearly at the same time. The object image formed by the optical system has opposite left and right directions. The level 6 is fastened to the boresight means by screws 7. When the target correcting lens is used, the central line of the bore can be adjusted to a horizontal position with reading accuracy of 4' by observing the centering degree of the bubble of the level gauge. If the sighting telescope is used for sighting, the sighting telescope is forgotten to take the sighting telescope out of the barrel mouth part, and then shooting is carried out, the bulge 21 arranged on the inserted link 2 can help to close air, so that the sighting telescope can be quickly pushed out of the bore by a sport projectile. Meanwhile, the end of the plunger 2 is provided with a recess 22 structure having a diameter larger than that of the contact portion of the projectile head fuse with the recess structure. When the head of the moving projectile is contacted with the inserted rod 2, the end part of the inserted rod 2 of the borescope can be prevented from expanding radially and extruding and expanding in the chamber, and the chamber explosion accident is avoided.
