Abstract

The utility model discloses an innovation of a hair device for firing. Firearms all adopt the front sight hair method of three points forming one line in present technique. The utility model makes the front sight change to a ring with a cross reticule, and makes the notch of a scale on a gun barrel change to a big notch which sheathes with a small notch. When shooting, the guns can hit a target when the target is coincident with the ordinate of the cross reticule and the center line of the small notch, or with an abscissa and the plane surface wire of the big notch. People with no shooting experience can also hit the target without difficulty. The utility model has the advantages of easy manufacture, low cost, convenient operation, simple maintenance, simple change and high hit ratio.

Description

Cross hair device for firing

The utility model belongs to the new design of shooting sighting device.

In the prior art, no matter be sportsman's gun of shooting usefulness, the gun of the usefulness of going hunting, or the gun of using in the military affairs, all adopt the foresight aiming mode of sight alignment.The foresight sighting system of sight alignment, be that a foresight is arranged on muzzle, one breach is arranged on the scale of gun barrel, as shown in Figure 1, when by the breach on shooting matter and the scale, foresight on the muzzle in line the time, just can open fire, its shortcoming is to do constant practice, and could improve hit rate when knowing a thing or two.

The purpose of this utility model provides a kind of low cost of manufacture, and is easy to use, can hit the shooting sighting device of the high visual target of difficulty easily.

Structure of the present utility model is as follows: at the ring of muzzle installation one band Crux graticule, this Crux graticule can be fixed, as shown in Figure 2, also can be adjustable, as shown in Figure 3.This band Crux target ring can be welded on the muzzle when making gun, causes fixedly, also can cause loop type, as shown in Figure 4, is enclosed within on the muzzle, when damaging, can change at any time.

As the sportsman practise with or go hunting with rifle etc., gun barrel temperature when the shooting state is no more than 70～80 ℃ low temperature gun, can select common iron hoop, copper ring for use, and the common metal silk is made the Crux graticule, wire is made the Crux graticule, diameter wiry in the present embodiment, is 1/3～1/2 millimeter, available welding manner is fixed, also can adopt the adhesive bonding,, then should use resistant to elevated temperatures alloy hoop and alloy wire to make as the high temperature gun of using in the military affairs.

The utility model cross coordinate formula sighting device can use the breach of scale on the former gun barrel, but preferably can use scale recess new departure of the present utility model, as shown in Figure 5.This scale recess new departure is having a little recess in big recess, be convenient to determine the tiny and accurate position of mid-point.In the present embodiment, the width of big recess is 3mm, and the degree of depth is 1.5mm, and little notch width is 0.5mm, and the degree of depth is 0.7mm.

During aiming, Crux target abscissa line overlaps with the planar line of big recess, ordinate overlaps with the center line of little recess, and the intersection point of the coordinate in length and breadth of Crux graticule with closed by the shooting matter body weight, as shown in Figure 6, this moment, the hit rate of opening fire was very high, as shooting, bullet trajectory as long as Crux target intersection point overlaps with bullet, just can hit.If by the shooting object is the object that upright walking people waits certain-length in vertical direction, if the center line of the ordinate line of Crux graticule and little recess with overlapped by shooting matter, just one hits (as shown in Figure 7) surely.If waited when the direction of level has the object of certain-length for flat people who crouches, as long as overlapped, just one hits (as shown in Figure 8) surely by the abscissa line on shooting matter and the Crux graticule and the planar line of big recess by shooting matter.

Use the utility model cross coordinate formula shooting sighting device, need not through long gunnery practice, hit easily.Thereby the utility model is that a kind of being easy to made, and cost is low, is convenient to maintenance, is convenient to change, easy to use, the novel shooting sighting device that shoots straight.

Claims

1, a kind of shooting sighting device is characterized in that including the ring of a band Crux graticule on muzzle.

2, shooting sighting device according to claim 1 is characterized in that including at big recess of one on the gun barrel scale and the little recess in big recess.

3, according to claim 1 and 2 described shooting sighting devices, the ring that it is characterized in that described band Crux graticule is the kink changeable type.

4,, it is characterized in that the Crux graticule on the ring of described band Crux graticule is fixed according to claim 1 and 2 described shooting sighting devices.
