Embodiment 1

[0020] like figure 1 As shown, a light weapon sight adjusting instrument of the present invention is composed of a slot 1, a top iron 2, a push rod 3 and an operating handle 4, wherein the slot 1 is a double-bottomed U-shaped slot; the top iron 2 is threaded Installed on one end of the card slot 1, the ejector rod 3 is installed on the other end of the card slot 1 through the trapezoidal thread, and the pitch of the trapezoidal thread is 3mm; The through hole is used for installing the operating handle 4.

[0021] A boss is provided in the middle of the push rod 3, and the boss and the push rod 3 are an integrated structure. The dial 5 is set on the outside of the boss of the ejector rod 3, and 100 scales are set at equal intervals in the circumferential direction of the dial 5 (combined with the pitch of the trapezoidal thread, each scale corresponds to 0.03mm), and set on the dial 5 0 tick marks. The locking nut 6 is used to lock the dial 5 on the outside of the boss, and...

Embodiment 2

[0028] like figure 2 As shown, the structure of the adjuster is basically the same as that of Example 1, and the main structural differences are: (1) The slot 1 is replaced by an O-shaped slot; (2) The pitch of the trapezoidal thread is 4mm; (3) The dial 5 is canceled and the lock nut 6, the scale is directly set on the boss of the ejector rod 3. Since the diameter of the boss is small, 40 scales are set at equal intervals in the circumferential direction of the boss (combined with the pitch of the trapezoidal thread, it can be known that each scale Corresponding to 0.1mm); (4) The top iron 2 is installed on the card slot 1 with a clearance fit, which is more convenient for disassembly and assembly, but the size of the gap should be controlled, otherwise the top iron 2 and the top rod 3 will not be able to Coaxial; (5) Replace the reference line with the reference mark installed on the side of the card slot 1, the reference mark is as image 3 shown.

[0029] When in use, t...

Embodiment 3

[0031] The structure of the adjuster is basically the same as that of Example 2, and the main structural differences are: (1) The slot 1 is replaced by a double-bottomed U-shaped slot; (2) The pitch of the trapezoidal thread is 5mm; (3) The dial 5 and The lock nut 6 is directly provided with a scale on the boss of the ejector rod 3. Since the diameter of the boss is small, 50 scales are set at equal intervals in the circumferential direction of the boss (combined with the pitch of the trapezoidal thread, each scale corresponds to 0.1mm)

[0032] The method of use is similar to that of Embodiment 1, so it is not repeated here.

Abstract

The invention proposes a sight adjustment instrument for light weapons, which is composed of a card slot, a top iron, a push rod and an operating handle. The connection mode is installed at one end of the card slot, the ejector rod is installed at the other end of the card slot through trapezoidal thread, the top iron and the ejector rod are coaxially installed, and the outer end of the ejector rod has a through hole for installing the operating handle. A boss is arranged in the middle of the push rod, and a scale is set on the boss; a special dial can also be arranged, and it is locked on the outside of the boss by a lock nut. When adjusting, put one end of the front sight shaft of the sight in the groove of the top iron, and the depression at the other end of the front sight shaft is supported by the positioning protrusion on the ejector rod, and the ejector rod is driven by rotating the operating handle, and the change of the scale value is observed, that is It can realize the precise adjustment of light weapon sights. The adjuster has the advantages of simple structure, high structural rigidity, high adjustment precision, and convenient continuous adjustment.

Description

technical field [0001] The invention relates to adjustment and calibration equipment for light weapons, in particular to a sight adjuster suitable for light weapons. Background technique [0002] From the day the firearm was produced, people paid great attention to its shooting efficiency. No matter how good a gun is, it is necessary for the shooter to always grasp the corresponding relationship between the aiming point and the impact point at different distances during use. The relationship changes accordingly, so it is very important to make timely corrections to the effect of gun fire. [0003] At present, more traditional methods are used, specifically manual operations such as tapping the depression on the end face of the sight shaft with a hammer or a blunderbuss to adjust the sight. This method has the following disadvantages: because it is difficult to control the strength by manual operation, it may be damaged; the strength of manual operation mainly depends on th...
