Abstract

The invention discloses a day and night dual-purpose shooting alignment mechanism, and belongs to the field of optical-mechanical integration. The mechanism consists of a division mirror 6, an illumination light source 8, a reflector 2, a reflector 7, a reflector 10, a semi-reflexive lens 4 and a mechanical structure, wherein the division mirror 6 is a plane convex lens and is positioned close to a focal plane of an optical system consisting of an objective 1 and the reflector 2 so as to play a role in providing a cross line and play a role of a field lens in the whole alignment mirror system. Marginal rays of rays reflected by the reflector 2 are refracted at the same time of simplifying the structure of the optical system, the diameter of each lens of a repeater group 9 is reduced, and the utilization of marginal energy is increased. Therefore, the volume of an alignment mirror can be reduced to certain extent, the weight of the day and night alignment mirror adopting the mechanism is reduced, and the concealment effect of the alignment mirror is improved.

Description

A kind of dual-purpose round the clock shooting pointing device

Technical field

This patent belongs to the integrated field of ray machine, relates to a kind of shooting pointing device, particularly a kind of dual-purpose round the clock shooting pointing device that helps dwindling the gun sight volume.

Technical background

Since gun sight comes out round the clock, be widely used at aspects such as social security, national security, military activities.Owing to will accomplish to unify round the clock, the light path on daytime and the light path at night need be combined, therefore the volume of gun sight is generally much bigger than the gun sight or the night sight that just use by day round the clock, this can strengthen the weight of gun sight round the clock, strengthens user's hidden difficulty simultaneously to a certain extent.This patent utilizes the optical property of field lens, and itself and graticle are combined, and develops a kind of shooting pointing device of gun sight volume round the clock that helps reducing.

Summary of the invention

The purpose of this patent is that design is a kind of dual-purpose round the clock, and helps reducing the shooting pointing device of gun sight volume.

As shown in Figure 1, the described dual-purpose round the clock shooting pointing device of this patent is made up of graduation mirror 6, lighting source 8, speculum 2, speculum 7, speculum 10, half anti-eyeglass 4 and frame for movement.When working by day, speculum 2 reflexes to graduation mirror 6 with the visible light that object lens receive, be coated with the silver cross line on the plane of graduation mirror, therefore after daytime, visible light was by the graduation mirror, the picture of a black cross hairs will be produced, reflex to relaying group 9 through speculum 7, reflex to half anti-eyeglass 4 through speculum 10 again, the picture of black cross hairs is reflexed to picture side by eyepiece 5 receptions by half anti-eyeglass.When working under the poor light condition night, by adjusting device speculum 2 to be removed, the optical signal that object lens 1 are received can amplify and final imaging by image intensifier 3.The diaphragm closure of the mirror of graduation simultaneously 6 belows, lighting source 8 is opened, and shines from the side on the silver cross line, makes the picture of a bright cross hairs of light formation of its light source for reflection illumination, through reflection, the transmission of speculum 7, relaying group 9, speculum 10 and half anti-eyeglass 4, finally receive by eyepiece 5.

As shown in Figure 2, the described graduation mirror 6 of this patent is a planoconvex spotlight, R1=∞ wherein, and R2=22.715 millimeter, the material of graduation mirror are K9.In use, graduation mirror 6 is positioned near the focal plane of the optical system that object lens 1 and speculum 2 form, makes it in whole sighting telescope system, promptly play the effect that cross hairs is provided, play the effect of field lens again.Here, because graticle and field lens unite two into one, form graduation mirror 6, this will simplify the structure of optical system, simultaneously because graduation mirror 6 plays the effect of field lens, so it can turn back and reflected back the rim ray of light by speculum 2, and it can be received by the optical system of back, so promptly help reducing the diameter of relaying group 9 each eyeglass, help increasing the capacity usage ratio at edge again to reach the purpose of raising system illuminance uniformity.

This patent is by adopting described graduation mirror 6, can reduce to adopt the volume of the gun sight round the clock of this mechanism to a certain extent, thereby reduces the weight of gun sight, improves its hidden effect.

The specific embodiment

Referring to Fig. 1, this patent is made up of graduation mirror 6, lighting source 8, speculum 2, speculum 7, speculum 10, half anti-eyeglass 4 and frame for movement.Wherein, graduation mirror 6 is a planoconvex lens, is contained near the focal plane of the optical system that object lens 1 and speculum 2 form, and the plane is towards speculum 2, and convex surface is towards speculum 7.Lighting source 8 is contained in the side of graduation mirror 6, opens when working night, impinge upon reflect to form cross hairs on the silver cross line of graduation mirror picture for the aiming use.Speculum 2 is contained in adjustable travel mechanism, be in when use daytime graduation mirror 6 under, and with the optical axis of object lens 1 angle at 45; By regulate travel mechanism remove it when using evening, and the light that object lens 1 are received can carry out picture signal by image intensifier 3 smoothly and amplify.Speculum 7 be in graduation mirror 6 directly over, and with the optical axis of relaying group 9 angle at 45.Speculum 10 is in the back of relaying group 9, and becomes 135 ° angle with the optical axis of relaying group.Half anti-eyeglass 4 be in speculum 10 under, and with the angle of 5 one-tenths 135 ° on eyepiece, wherein the one side towards object lens is coated with anti-reflection film 1, is coated with half anti-film towards the one side of eyepiece 5, inverse ratio is 2: 1 thoroughly.

Referring to Fig. 3, Fig. 4, the graduation mirror of this patent is contained in the graduation frame 12, is fixed by graduation trim ring 13.Graduation frame 12 is placed on the graduation skeleton frame 11, and they become the graduation governor motion with adjustment screw 14, adjustment screw 15, footstock 16 and spring mutual group.The side of graduation frame 6 makes its 3 side wherein be mutually 120 ° through precision finishing machine processing, and is withstood respectively by spring by adjustment screw 14, adjustment screw 15 and footstock 16, is fixed.In use footstock 16 maintains static by hold-down screw, adjustment screw 14 and adjustment screw 15 can move along adjusting before and after their axis directions separately, by spring action, drive graduation frame 12 and do corresponding mobile, thereby regulate the position of graduation mirror, make the cross hairs crosspoint on the graduation mirror be taken aim at object, human eye three " sight alignment ", reach the purpose of aiming with quilt.

The turn back character of rim ray of this patent utilization field lens combines graticle with field lens, composition graduation mirror, thus reduce to be furnished with the volume of the gun sight round the clock of this patent mechanism to a certain extent, thus alleviate the weight of gun sight and strengthen its hidden effect.
