Technical field

The utility model relates to rifles to take aim at manufacturing technology field, and in particular to a kind of rifle takes aim at the dedicated adjustment device of adjustment screw.

Background technique

Traditional gun sight can be generally divided into holographic diffraction sight, interior red green gun sight and laser sighting device etc..19 generation It records the forties, some U.S.'s firearms skilled workers start to manufacture the firearms with optical aiming device.The Mo Genzhan of New York in 1848 Mu Si devises a kind of tubular sighting device of length same as gun barrel, and the latter half of of the device is mounted with glass lens, and has 2 Cross hairs of the item for aiming.Later, similar sighting device was applied in American Civil War.But really there is practical value Gun sight be then born in 1904, by the karr Zeiss development of Germany, and used in the World War I.At second In world war, gun sight starts mature.

Till now, gun sight is broadly divided into following three categories: formula of looking in the distance gun sight, collimation formula gun sight and reflective Gun sight.Wherein with look in the distance formula gun sight and reflex sight it is the most popular.

Rifle, which is taken aim at, to need to carry out many adjustment after finalization of the manufacture, screws adjustment, tradition side including to adjustment screw Formula using manually adjusting, take aim at by proficiency hand-held gun, and another hand rotates adjustment screw, and this mode using artificial naked eye due to being seen It examines, therefore efficiency is very low, and Adjustment precision is poor, therefore our company has developed a kind of calibration console, but rifle is taken aim at and is placed on calibration console After upper fixation, adjustment screw is inconvenient to screw due to very short, so our company has developed a kind of rifle again, to take aim at adjustment screw dedicated Device is adjusted, thus this case is just given birth to.

Utility model content

In order to solve the above technical problems, the purpose of this utility model is to provide a kind of rifles to take aim at the dedicated adjustment dress of adjustment screw It sets, operator is facilitated to adjust the adjustment screw that rifle is taken aim on calibration console.

To achieve the above object, a kind of rifle of the utility model takes aim at the dedicated adjustment device of adjustment screw, including cylinder, described Cylinder offers circular groove along its axial direction, and the circular groove has at least one step surface, and circular groove is divided at least two by the step surface The internal diameter of a sleeve, each sleeve is all different and its inner wall is equipped with several anti-slop serrations；The outer circumference surface of the cylinder Equipped with connecting plate, the upper surface of the connecting plate is rotatably connected to turning handle.

Preferably, the outer circumference surface of the cylinder is equipped with internal diameter at corresponding sleeve and identifies.

Preferably, the cross section of the anti-slop serrations uses triangle.

Alternatively, the cross section of the anti-slop serrations is using trapezoidal.

Preferably, along the shaft that is axially arranged with of cylinder, the turning handle is hollow structure and set for the upper surface of the connecting plate Outside shaft.

Preferably, it is carved on the turning handle and is equipped with anti-skid chequer.

The utility model compared with prior art, the beneficial effect is that:

After taking aim at and being fixed on calibration console by rifle, first this adjustment device is sheathed on adjustment screw, the set of corresponding internal diameter The outer circumference surface of cylinder and adjustment screw coincide, and anti-slop serrations are caught between the two neighboring tooth of adjustment screw outer circumference surface, then around circle The axial rotation turning handle of column can turn adjustment screw, and operator is facilitated to adjust the adjustment screw that rifle is taken aim on calibration console；Extremely A few step surface can form at least two sleeves in circular groove, for being adapted to the adjustment screw of a variety of outer diameters, the scope of application It is relatively wide.
