Abstract

The utility model discloses a gun sighting device, which comprises a rear sight arranged at the rear end of a gun body for sighting and a front sight arranged at the front end of the gun body. The essential point of the technical scheme is that the gun sighting device comprises the rear sight arranged at the rear end of the gun body for sighting and the front sight arranged at the front end of the gun body, and the gun sighting device is characterized in that a slit used for sighting is arranged in the middle of the front sight, wherein the product of the width of the slit and the distance between (S1+S2) a focus point and a target is equal to that of the average width K2 and the distance S1 between the focus point and the front sight, namely K1(S1+S2)=S1K2. Purpose of the gun sighting device is overcoming the weakness of complex structure and inconvenient usage of the prior art and providing a sighting device which is capable of fast aiming and simple in structure. Further a hyperbolic front sight is arranged on the front sight, which achieves fast aiming with high accuracy by utilizing the optical imaging principle, therefore the gun sighting device not only increases aiming speed and saves aiming time, but also is simple in structure, convenient in using and low in production cost.

Description

A kind of gun sight

[technical field]

The utility model relates to a kind of weapon aiming parts, a kind of rifle of saying so more specifically.

[background technology]

Because the route of bullet flight is a parabola, in order to hit the human body target of different distance, target in the shooting different distance must adopt different aiming height, sighting device on the existing various firearms all is a height of regulating aiming by the height of regulating sight, governing speed is slow, prolongs the aiming time, and the adjusting sight need be provided with special governor motion, the sighting device of rifle will be very complicated, uses inconvenient.Need a kind of sight that again can slewing simple in structure and be applied to various firearms.

[utility model content]

The utility model purpose is to have overcome complex structure in the prior art, uses inconvenient deficiency, but a kind of slewing and sight simple in structure are provided.

The utility model is achieved through the following technical solutions:

A kind of gun sight comprises being arranged on rifle body rear end sight that is used to aim at and the foresight that is located at rifle body front end, it is characterized in that being provided with the slit that is used to aim at, the distance (S between the width in described slit and focus point and the goal in the middle of the described foresight ₁+ S ₂) long-pending equaling between focus point and the foresight apart from S ₁Mean breadth K with goal ₂Amassing, i.e. K ₁(S ₁+ S ₂)=S ₁K ₂

Aforesaid a kind of gun sight is characterized in that the rear side of described foresight is provided with a plurality of aiming scales that are used for different range aimings.

Aforesaid a kind of gun sight, the width that it is characterized in that described slit is up big and down small.

Compared with prior art, the utility model has following advantage:

The utility model is provided with the hyperbola foresight on foresight, utilize the image-forming principle of light to realize slewing, degree of accuracy height; Improve pointing velocity, saved the aiming time; Simple in structure, easy to use, low cost of manufacture.

[specific embodiment]

A kind of gun sight, comprise and be arranged on rifle body 1 rear end sight 2 that is used to aim at and the foresight 3 that is located at rifle body 1 front end, it is characterized in that being provided with the slit 301 that is used to aim in the middle of the described foresight 3, the width in described slit 301 are goals 10 with foresight 3 between distance become the hyperbolic function relation, the width in described slit 301 is up big and down small.The width K in described slit 301 ₁And the distance (S between focus point and the goal 10 ₁+ S ₂) long-pending equaling between focus point and the foresight 3 apart from S ₁Mean breadth K with goal ₂Long-pending, promptly

The rear side of described foresight 3 is provided with a plurality of aiming scales 300 that are used for different range aimings.The height h=S of aiming scale 300 ₁Tg θ, θ is the firing angle of aiming scale respective distances, the firing angle difference of different distance.

During use, be adjusted to the shoulder of shooting human body target with the hyperbola in the slit 301 of foresight 3 tangent, form similar triangles between human body shoulder and foresight slit 301 and ejaculator's the eyes, ejaculator's eyes are focus point, so just can aim at the target of different distance with the width in foresight slit 301.

Claims (3)

1, a kind of gun sight, comprise and be arranged on sight (2) that rifle body (1) rear end is used to aim at and the foresight (3) that is located at rifle body (1) front end, it is characterized in that being provided with the slit (301) that is used to aim at, the width (K of described slit (301) in the middle of the described foresight (3) ₁) and focus point and goal (10) between distance (S ₁+ S ₂) the long-pending distance (S between focus point and the foresight (3) that equals ₁) with the mean breadth (K of goal ₂) amassing, i.e. K ₁(S ₁+ S ₂)=S ₁K ₂

2, a kind of gun sight according to claim 1 is characterized in that the rear side of described foresight (3) is provided with a plurality of aiming scales (300) that are used for different range aimings.

3, a kind of gun sight according to claim 1, the width that it is characterized in that described slit (301) is up big and down small.
