Embodiment 1

[0020] Such as 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, ...

Embodiment 2

[0028] Such as 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...

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 provides a light weapon sight adjusting instrument. The adjusting instrument is composed of a clamping groove, a jacking block, a jacking rod and an operation handle; the clamping groove is a double-bottom U-shaped clamping groove or O-shaped clamping groove, the jacking block is mounted at one end of the clamping groove in movable connection manners of the threaded manner or clearance fit manner, the jacking rod is mounted at the other end of the clamping groove in a trapezoidal threaded manner, and the jacking block and the jacking rod are coaxially mounted; a through hole is formed in the outer end of the jacking rod and used for mounting of the operation handle. A boss is arranged in the middle of the jacking rod, and scales are arranged on the boss; a dedicated dial is arranged, and is locked on the outer side of the boss through a locking nut; during adjustment, one end of a sight star shaft of a sight is arranged in the groove of the jacking block, a sinking position of the other end of the sight star shaft is jacked by a positioning protrusion on the jacking rod, the jacking rod is driven by rotating the operation handle, changes of scale rules are observed, and precise adjustment of a light weapon sight is achieved. The adjusting instrument has the beneficial effects of being simple in structure, large in structural rigidity, high in adjusting precision, convenient to continuously adjust and the like.

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...
