The utility model content
The purpose of this utility model provides the function that has range finding and Ballistic Compensation simultaneously, so that a kind of gun sight graticle with distance measurement function that the user accurately strikes target.
To achieve these goals, the utility model is achieved in that a kind of gun sight graticle with distance measurement function comprises angle of site graduation mark 1 and width angle graduation mark 2, also is provided with Ballistic Compensation scale 3.
Described angle of site graduation mark can be provided with 8 scales, and each scale is represented 1 mil, the highest 8 mils of surveying;
Described width angle graduation mark can be provided with 16 scales, and each scale is represented 1 mil, the wideest 16 mils of surveying.
Described Ballistic Compensation scale can design 5 Ballistic Compensation scales, the Ballistic Compensation point of the corresponding respective distance of each Ballistic Compensation scale.
The utility model gun aiming device graticle is provided with the Ballistic Compensation scale when being provided with the range finding scale, utilized the mil method to measure target range earlier, utilize Ballistic Compensation to carry out aimed fire then, effectively raise the precision of small arms firing, have advantage of low manufacturing cost simultaneously.
The specific embodiment
Below in conjunction with the drawings and specific embodiments a kind of gun sight graticle with distance measurement function of the utility model is described in detail.
The principle explanation
The principle of mil method range finding is: calculate the distance between object and the observer under the situation of the height of known object or width.
Mil formula: L=1000XH/a (1)
In the formula: L represents the distance (rice) of observer to target
H represents the width or the height (rice) of target
A represents angular elevation or target width angle (mil) measured with the graticle of gun aiming device
By formula (1) as can be known,, utilize rifle to take aim on the graticle horizontal mil line again or vertical mil line is measured angular elevation or width angle, can obtain the distance L of observer to target as long as know the width or the height of target.
A kind of gun sight graticle with distance measurement function as shown in Figure 1, comprises angle of site graduation mark 1 and width angle graduation mark 2, also is provided with Ballistic Compensation scale 3 in addition.Angle of site graduation mark 1 can be provided with 8 scales altogether, and each scale is represented 1 mil, the highest 8 mils of surveying.Width angle graduation mark 2 can be provided with 16 scales, and each scale is represented 1 mil, the wideest 16 mils of surveying.Angle of site graduation mark 1 has 8 scales, and each scale is represented 1 mil, the highest 8 mils of surveying; Width angle graduation mark 2 has 16 scales, and each scale is represented 1 mil, the wideest 16 mils of surveying.The actual height of object or width can estimate, and the user measures the mil size according to the height direction of object again, perhaps measures the mil size according to the transverse width of object, and substitution mil formula then (1) obtains the distance L of object at last.Object for different distance, the Ballistic Compensation of being done is different, the utility model Ballistic Compensation scale 3 can be provided with 5 Ballistic Compensation scales according to actual needs, under the known situation of object distance L, can find corresponding Ballistic Compensation point according to graticle 6, concrete index path as shown in Figure 4.The intersection point place of abscissa and ordinate is the Ballistic Compensation point of 100m, and next coming in order are Ballistic Compensation points of 200m, 300m, 400m, 500m, that is to say to make the user that 500m is realized precision strike with interior object.
Embodiment 1
As shown in Figure 2, when finding the prey stag 4 of distant place, can utilize the width angle scale 2 on the graticle 6 to measure the distance of prey to the observer.The user only needs scale is aimed at stag corner the widest part, measures the mil a in corner then, and a is 8 as shown in Figure 2, and the stag corner width developed width of growing up is about 2m, can try to achieve the distance of prey to the observer according to mil formula
L=1000X?2m/8=250m (2)
By formula (2) as can be known distance L be 250m, so the aiming point after the Ballistic Compensation drops on the centre position 5 of scale 200m-300m, if the user need shoot the neck of prey, then the user can aim at the shooting position to aiming point, as shown in Figure 3.
The utility model is not limited to above-mentioned embodiment, if to various start or modification does not break away from spirit and scope of the present utility model of the present utility model, if these are changed and modification belongs within claim of the present utility model and the equivalent technologies scope, then the utility model also comprises these changes and modification.
