Abstract

Disclosed is a gun sighting mirror which is suitable for submachine guns of model 56, various firearms for civilian purposes, and guns with other models. The utility model is composed of an objective lens 1, a field lens 2, an image rotation lens 3, a reticle 4, an eyepiece 5, a lens barrel 10, a spacing ring 12, fixed rings 9, 11 and 14, a pistol 13, and a reticle adjustment mechanism. The gun sighting mirror is characterized in that the reticle adjustment mechanism is a planar double track type reticle adjustment mechanism that is composed of a guide plate 6, a transversal guide plate 7 and a longitudinal guide plate 8. The gun sighting mirror has the characteristics of favorable shock resistance, small volume and beautiful appearance.

Description

Gun sighting mirror

A kind of riflescope, for the rifle of equipping 56 formula tommy guns and other model designs, and can with the supporting well use of all kinds of civilian gun.

At present, the graticle guiding mechanism that domestic and international rifle is taken aim at adopts cantilever structure mostly, and turning to lens barrel and graticle is one, and turning between lens barrel and the eyepiece is to be flexible coupling.This structure not only makes the length that rifle takes aim at increase, and the vibrations during shooting can influence pointing accuracy.The graticle of some optical instrument adopts single sliding block mechanism (seeing " optical instrument " handbook), and graticle is fixed with shell fragment, and not only adjustment amount is very little but also can not be shock-resistant when shooting for it, still can not solve the shock-resistant problem of gun aiming device.

In addition, the producer that the domestic production rifle is taken aim at is (as 288 factories, 298 factories) rifle of being produced take aim at be 4 * 32 and other all kinds of changes times rifle take aim at, its length is all more than 260mm, when being the supporting use of military gun, the problem that shell case and gun aiming device body are collided in the time of can not solving shooting, and length is long, weight is big, is unfavorable for carrying.

The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of impact-resistant riflescope is provided.

The riflescope that provides a kind of length short and small is provided the further purpose of the utility model.

Riflescope of the present utility model is made up of object lens, eyepiece, image rotation lenses, graticle, lens barrel, spacer ring, retainer plate and graticle guiding mechanism, it is characterized in that the graticle guiding mechanism is by guide plate, transverse guides, the two guide rail mechanisms of the plane formula that longitudinal guide plate is formed, have the guiding slot port of a rectangle on the guide plate of annular, two discrete voussoirs that can slide in the guide plate notch are arranged on the transverse guides, have on the other end one with the perpendicular rectangle guiding slot port of two discrete voussoir lines, the rectangle longitudinal guide plate can be slided along this guiding slot port.This rifle is taken aim at and can be carried out independent correction in X, Y direction, has reliable impact resistance, and optical length is taken aim at the length weak point than the rifle that adopts the cantilevered guiding mechanism.

In said structure, with 1.4 times the multiplying power of changing into of 1 times relay lens, the numerical aperture N value 1:2 of object lens under the prerequisite that guarantees the picture element and the angle of visual field, has shortened the focal length of object lens effectively, thereby has significantly reduced the length of whole optical system.

An embodiment of the present utility model is below described.

Referring to accompanying

drawing

1,2,3.

This gun aiming device is by object lens 1, field lens 2, and image rotation lenses group 3, graticle 4, eyepiece 5 and lens barrel 10, spacer ring 12, retainer plate 9,11,14, handwheel 13 and graticle guiding mechanism are formed.The adjustment of graticle 4 is referring to Fig. 3.Longitudinal guide plate 8, transverse guides 7, guide plate 6 constitutes the two guide wheel mechanisms in plane.Have the guiding slot port of a rectangle on the guide plate 6 of annular, two voussoirs that match with notch on the guide plate 6 are arranged on the transverse guides 7, also have on the transverse guides 7 one with the perpendicular rectangle guiding slot port of bottom voussoir line, rectangle guide plate 8 can be slided along this guiding slot port.Graticle 4 is fixed on the longitudinal guide plate 8, and rotation vertically adjustment handwheel promotion longitudinal guide plate 8 is slided in the notch of transverse guides 7, and rotation is laterally adjusted handwheel promotion transverse guides 7 and slided in the notch of guide plate 6, and guide plate 6 and lens barrel are connected.Because graticle can be at X, Y direction is carried out independent correction, therefore has reliable impact resistance, and optical length is taken aim at the length weak point than the rifle that adopts the cantilevered guiding mechanism.

The optical system aspect adopts 1.4 times lens relay system to replace 1 times relay system, makes the numerical aperture of object lens reach 1:2, shortened the focal length of object lens effectively, thereby significantly reduced the length of whole optical system, the picture element of gun aiming device is good simultaneously, and enough angles of visual field are arranged.When the multiplying power of gun aiming device was 2.5 times, the length of product can be in 130mm, the angle of visual field 6 degree, and walking about of graticle was controlled in 2 seconds.

The utility model is owing to adopted the two guide rail adjusting mechanisms in plane and 1.4 times of image rotation lens, make this gun aiming device good in picture matter, under the big prerequisite of the angle of visual field, had the short and small characteristics of good impact resistance and length, effectively overcome the deficiency of existing gun aiming device, can be have well propped up supporting use with rifle and the civil-use gun of 56 formula tommy guns and other model.
