Description

Technical Field

[0001] The utility model belongs to the technical field of firearms adjustment equipment, and in particular relates to a portable mechanical aiming and correction instrument. Background Art

[0002] Due to different climates in different regions, improper training and maintenance during normal times, weapons and mechanical standard tools will experience varying degrees of natural wear, resulting in reduced weapon shooting standards and accuracy, which directly affects the implementation of combat readiness. In order to keep weapons in a good combat readiness state at all times and to deal with the shooting effects of weapons, it is necessary to calibrate weapons with unqualified shooting effects to ensure that the weapons can shoot accurately and exert their maximum technical and tactical performance.

[0003] At present, optical sights have their corresponding calibrators, but there are few calibrators for mechanical sights. In particular, most of the firearms we currently use do not use optical sights for shooting, but use mechanical sights for aiming and shooting, but it is very difficult to calibrate mechanical sights.

[0004] Therefore, a design concept is proposed to solve the following technical problems:

[0005] First: When shooting, if there is a deviation between the aiming point and the impact point, the gun can be calibrated normally if the deviation is small. Once the deviation is large and the bullet does not hit the target, the gun cannot be calibrated normally, which seriously affects the overall shooting process.

[0006] Second: If the deviation is large, although the chamber calibration method can be used for rough correction, it is necessary to disassemble the gun, fix the gun, and re-aim twice (chamber aiming and machine aiming). The whole process is time-consuming and labor-intensive, and the accuracy is very low. Utility Model Content

DETAILED DESCRIPTION

[0024] In order to more clearly illustrate the technical solutions in the embodiments of the utility model or the prior art, the utility model will be briefly introduced below in combination with the drawings and the description of the embodiments or the prior art. Obviously, the following description of the structure of the drawings is only some embodiments of the utility model. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work. It should be noted that the description of these embodiments is used to help understand the utility model, but does not constitute a limitation of the utility model.

[0025] Example:

[0026] like Figure 1-3 As shown, this embodiment provides a portable mechanical aiming and correction instrument, including a laser lamp head 100 and a main body 200, the main body 200 includes a battery compartment 201 and a tail vertebra 203, the tail vertebra 203 is integrally formed at the tail end of the battery compartment 201, and a dry battery 400 is arranged inside the battery compartment 201. The laser lamp head 100 is detachably connected to the front end of the battery compartment 201, and the tail vertebra 203 is inserted into the inside of the gun barrel. The diameter of the tail vertebra 203 matches the inner diameter of the gun barrel, and a wear compensator 300 is arranged at the tail of the tail vertebra 203, and the tail vertebra 203 changes its tail section diameter through the wear compensator 300.

[0027] Specifically, by inserting the calibration instrument into the gun barrel and pressing the power switch 103 of the laser lamp head 100, the laser is projected to the calibration mark 500 and converges into a point. By rotating the main body 200, it is observed whether the laser point is stationary to determine whether the calibration instrument and the gun barrel are coaxial.

[0028] If the laser spot moves in a circle on the calibration mark 500, it means that the calibration instrument is not coaxial with the gun barrel. At this time, it is necessary to adjust the vertical adjustment knob 101 and the horizontal adjustment knob 102 provided on the laser lamp head 100 to adjust the laser beam to be coaxial with the gun barrel before the installation steps of the calibration instrument can be completed;

[0029] Subsequently, by aligning the front sight with the adjustment mark 500 and adjusting it to coincide with the laser point, the precise adjustment of the mechanical sight can be completed. This calibrator can improve the efficiency of gun calibration, so that the gun can be basically calibrated before live-fire shooting, saving ammunition consumption, saving calibration time, and improving the overall training quality and efficiency. This calibrator does not require any precision measuring instruments for assistance. It only needs to know the relevant parameters of the gun and use custom reference objects for rapid calibration and aiming. It is very suitable for use in harsh environments and arduous tasks, thereby effectively improving the hit rate of soldiers in battlefield environments and improving their own survival rate.

[0030] In a preferred embodiment of the utility model, further, a guide cone 301 is provided at the front end of the wear compensator 300, and three expansion columns 302 are sequentially provided along the length direction of the guide cone 301, the diameters of the three expansion columns 302 are increased sequentially, and the three expansion columns 302 are connected by inclined surfaces, and a base plate 303 is provided at the tail end of the wear compensator 300.

[0031] In a preferred embodiment of the utility model, further, a positioning hole 204 is opened in the middle of the tail end of the coccyx 203, and a plurality of expansion grooves 205 are evenly opened around the positioning hole 204. The plurality of expansion grooves 205 divide the hole wall of the positioning hole 204 into a plurality of expansion wings, and the wear compensator 300 is inserted into the positioning hole 204 to squeeze each expansion wing outward.

[0032] Specifically, in order to prevent the correction instrument from being worn during long-term use and thus reducing its fit with the gun barrel, a wear compensator 300 is provided to expand the diameter of the tail vertebrae 203 through the wear compensator 300 to compensate for the loss of size due to wear, so that it can restore its adjustment accuracy and effectively extend the service life of the correction instrument, thereby reducing the cost of repurchasing the equipment and saving costs for the unit.

[0033] In a preferred embodiment of the utility model, further, a laser emitter 104 is arranged at the center of the front end of the laser lamp head 100, a vertical adjustment button 101 and a horizontal adjustment button 102 are arranged near the front end of the laser lamp head 100, and the laser lamp head 100 is also provided with a power switch 103. The calibrator achieves endurance through a dry battery 400, which is convenient for replacing the power supply and carrying. Moreover, by providing a waterproof structure, it can be carried during field training to adjust the firearm at any time.

[0034] In a preferred embodiment of the present invention, further, the central axes of the laser lamp head 100, the main body 200 and the wear compensator 300 are all arranged to coincide with each other.

[0035] In a preferred embodiment of the present invention, further, the maximum diameter of the guide cone 301 is larger than the diameter of the positioning hole 204. By designing the guide cone 301 to be conical, the expansion wings can be very conveniently opened to adjust the diameter of the tail vertebra 203, thereby quickly compensating for the worn tail vertebra 203, thereby making the present correction instrument more adaptable to the harsh environment of the battlefield, so that it can still maintain accuracy and be used normally in harsh environments.

[0036] In a preferred embodiment of the present invention, further, an external thread 105 is provided at the rear end of the shell of the laser lamp head 100, and an internal thread 202 is provided at the top of the inner wall of the battery compartment 201. The laser lamp head 100 is threadably connected to the inside of the battery compartment 201 through the internal thread 202 and the external thread 105.

[0037] In a preferred embodiment of the present invention, further, the laser projected by the laser transmitter 104 is concentrated in a point shape on the calibration mark 500. The calibration mark 500 can be an actual marker or an automatic reference by the operator in the field. By specifying a reference object and aligning the laser point with it to adjust the sight, the adjustment speed can be greatly improved, thereby effectively improving the performance of the firearm and the survivability of a single soldier.

[0038] The working principle of this portable mechanical aiming and correction instrument:

[0039] Taking the Type 95 automatic rifle as an example, when the shooting target distance is one hundred meters, the aiming angle is 4.2 mils (can be checked in the shooting table). It is known that 1 mil is equal to 0.06", and 4.2 mils is equal to 0.252". If the height of the mechanical sight of the Type 95 automatic rifle is X, the distance from the crosshairs to the intersection point can be obtained according to trigonometric functions, which is equal to Y = X / tan0.252". At this time, the adjuster moves to a distance Y of 500 (focus) from the calibration mark, raises the gun to make the laser point coincide with the calibration mark 500, and then adjusts the sight forward, backward, left and right to make the crosshairs coincide with the laser point, thus completing the calibration operation of the firearm mechanical sight. This method is also fully applicable to the calibration operation of other gun sights.

[0040] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
