Description

Technical Field

[0001] The present invention relates to the technical field of firearm calibration, and specifically to a compass-type firearm calibrator. Background Art

[0002] During the use of firearms, ensuring shooting accuracy is of utmost importance, and the precise calibration of mechanical sights is a crucial link in achieving this goal. The mechanical sights of firearms mainly consist of a rear sight and a front sight. When shooting, it is necessary to aim at the target by means of the straight line formed by the rear sight notch and the front sight. However, when the barrel is bent or deformed, or the front sight is not accurately calibrated, the dispersion of projectiles during shooting will increase significantly. At this time, it is necessary to adjust and calibrate the mechanical sights of the firearm to ensure shooting accuracy and meet the actual use requirements. Whether in military operations, law enforcement operations or shooting training scenarios, accurate sights are indispensable.

[0003] Currently, for the adjustment and calibration of firearm mechanical sights, a method based on the analysis of projectile impact point data is adopted. Specifically, it is necessary to calculate the average impact point based on the impact points of projectiles on the target board, determine its distances in the X and Y directions from the bull's-eye, then calculate the correction amount through a calibration formula, and finally adjust the height of the front sight and the left and right of the rear sight according to this correction amount. Among them, the front sight is screwed into the front sight base through a thread, and the front sight is rotated by means of a front sight wrench to realize the up and down adjustment of the front sight within the front sight base; the left and right adjustment of the rear sight is completed by using a screwdriver to align with the rear sight slide. In actual operation, the adjustment amount of the front sight is measured by the number of turns of the front sight wrench.

[0004] However, this traditional firearm calibration method has many drawbacks. For example, in a tense military training, soldiers need to quickly calibrate their firearms to participate in simulated combat. However, due to the lack of a specific zero-reference on the 360-degree circumference for the number of turns, only approximate estimation can be carried out, resulting in extremely limited adjustment accuracy. In order to achieve ideal shooting accuracy, soldiers have to shoot multiple times, and after each shooting, they have to recalculate and adjust the calibration according to the new impact points. This process not only consumes a large amount of ammunition, increases labor costs, prolongs training time, causing a waste of time costs, but also frequent shooting will accelerate the wear of the barrel, bringing additional economic losses. Therefore, the present invention provides a compass-type firearm calibrator to solve the deficiencies existing in the prior art. Summary of the Invention

The second assembly component includes a pointer 5 and a screw 6. The outer side of the pointer 5 is attached to the outer side of the main shaft 1. The outer side of the main shaft 1 is provided with Mounting hole 4, one end of the screw 6 passes through the internal through hole of the pointer 5 and is connected with the inner thread of the mounting hole 4. When assembling components such as the washer 10, the compass dial 7, and the rubber ring 11, the washer 10 is placed between the bushing 9 and the compass dial 7 to play a role in buffering and uniform force, avoiding wear or loose installation caused by direct contact. The rubber ring 11 is located below the compass dial 7. On the one hand, it can increase the friction to prevent the compass dial 7 from accidentally rotating. On the other hand, it can also play a certain sealing and shock-absorbing effect. The outer side of the main shaft 1 is provided with a thread and is located below the limit ring 8. The outer sleeve of the main shaft 1 is provided with a bushing 9, and the top of the bushing 9 fits with the outer side of the limit ring 8 to ensure the stable installation of the subsequent sleeve components. The outer side of the bushing 9 The main sleeve is provided with a compass dial 7, a gasket 10 and a rubber ring 11. The U-shaped block 13 is engaged with the limiting groove 12 on the outer side of the bushing 9 through the limiting block 15 in the internal combination hole 14. This design not only limits the axial movement of the bushing 9 on the main shaft 1, but also ensures that the bushing 9 can slide relative to the U-shaped block 13 within a certain range, thereby realizing the flexible rotation of the compass dial 7. The outer sleeve of the main shaft 1 is provided with a U-shaped block 13, and the interior of the U-shaped block 13 is provided with a combination hole 14. The inner side of the combination hole 14 is fixedly connected with two limiting blocks 15. The outer side of the bushing 9 is slidably connected with the inner side of the combination hole 14. The outer side of the bushing 9 is provided with two limiting grooves 12. The outer side of the limiting block 15 is engaged with the inner side of the limiting groove 12. The U-shaped block 1 The top of 3 contacts the outside of the rubber ring 11, the outer sleeve of the main shaft 1 is provided with a threaded ring 16, the inner side of the threaded ring 16 is connected to the outer thread of the main shaft 1, and the two circular holes 18 opened inside it are convenient for the operator to manually tighten or loosen the threaded ring 16 to adjust the axial position of the U-shaped block 13 and other components on the main shaft 1, further ensuring the stability of the entire device, the threaded ring 16 has two circular holes 18 opened inside, the front sight assembly, which is arranged at the bottom of the main shaft 1, is the basic structure of the gun front sight, the front sight assembly includes a front sight constellation, the assembly hole inside the front sight constellation is threadedly connected to the front sight block, this connection method is convenient for replacing front sight blocks of different specifications according to actual needs, the front sight constellation is provided with an assembly hole, and the inner side of the assembly hole is threadedly connected with the front sight block,The sighting star is located inside the U-shaped clamping block 13. A combined groove 17 is opened at the bottom of the main shaft 1. The top end of the sighting star block is engaged with the inner side of the combined groove 17. After the combined groove 17 at the bottom of the main shaft 1 is engaged with the top end of the sighting star block, rotating the main shaft 1 can accurately adjust the position of the sighting star block.

[0020] Specifically, when assembling the compass-type gun calibrator, first, sleeve the bushing 9 on the outside of the main shaft 1. The bushing 9 not only protects the main shaft 1, but also provides a stable support basis for other components that are subsequently installed, ensuring that the relative positions of various components on the main shaft 1 are accurate. Then, sleeve the washer 10. The washer 10 is located between the bushing 9 and the compass dial 7. It can effectively buffer the pressure between components and prevent wear caused by direct contact. At the same time, it evenly disperses the pressure, allowing the compass dial 7 to be installed more firmly. Then, install the compass dial 7, which is a key component for the gun calibrator to read calibration data. Its scale design can intuitively reflect the offset value of the front sight adjustment. The rubber ring 11 is placed under the compass dial 7. With its good elasticity and friction, it can prevent the compass dial 7 from rotating accidentally and ensure stable readings. On the other hand, it can also play a certain sealing role, reduce the impact of external dust and other impurities on the internal structure, and to a certain extent alleviate the vibration generated when the device is working. Finally, the U-shaped block 13 is put on the main shaft 1. The U-shaped block 13 is engaged with the limiting groove 12 on the outer side of the bushing 9 through the limiting block 15 in the internal combination hole 14. This ingenious design not only limits the axial movement of the bushing 9 on the main shaft 1, but also ensures The stability of the entire device structure is ensured, and the bushing 9 can slide relative to the U-shaped block 13 within a certain range, thereby giving the compass dial 7 the ability to rotate flexibly, providing the necessary conditions for subsequent calibration operations. At this point, the bushing 9, the gasket 10, the compass dial 7, the rubber ring 11 and the U-shaped block 13 are sequentially sleeved on the outside of the main shaft 1 from top to bottom. After completing the above steps, the threaded ring 16 is sleeved on the external thread of the main shaft 1 for installation. The inner side of the threaded ring 16 is tightly matched with the external thread of the main shaft 1, and the two circular holes 18 opened inside it are convenient for the operator to manually tighten or loosen it. By adjusting the position of the threaded ring 16 on the spindle 1, the axial position of the U-shaped block 13 and other components connected thereto on the spindle 1 can be accurately adjusted, further enhancing the stability of the entire device and ensuring that the components will not be displaced due to factors such as vibration during the subsequent gun calibration process, thereby affecting the calibration accuracy. Finally, the pointer 5 is installed at the mounting hole 4 through the screw 6. The pointer 5 fits on the outside of the spindle 1. After the installation is completed, it can intuitively indicate the scale value on the compass dial 7, which is convenient for the operator to quickly read the relevant data of the sight adjustment. Then the combination at the bottom of the spindle 1 can be The groove 17 is combined with the top of the sight block. This tight combination ensures stable power transmission between the main shaft 1 and the sight block, so that in the subsequent adjustment process, rotating the main shaft 1 can accurately drive the sight block to move, laying the foundation for accurate calibration of the gun sight. After the combination is completed, manually rotate the compass dial 7 for zeroing. The zeroing operation is an important starting step of the entire calibration process. By returning the scale of the compass dial 7 to zero, a unified and accurate benchmark is provided for the subsequent reading of the offset value caused by the sight adjustment, thereby ensuring the reliability and consistency of the calibration data.After zero calibration is completed, rotate the torsion bar 3 to drive the main shaft 1 to rotate. Since the torsion bar 3 and the assembly hole 2 at the top of the main shaft 1 are connected by an interference fit, this connection is extremely stable, enabling the rotational power to be stably transmitted to the main shaft 1 when the torsion bar 3 is rotated. After the main shaft 1 rotates, it further drives the sight block tightly connected to it to rotate. Because the sight block is associated with the firearm sight, the change in the position of the sight block directly corresponds to the adjustment of the position of the firearm sight. In this way, the position of the sight block can be accurately raised or lowered to adapt to different shooting distances and target requirements. During actual shooting, the operator can directly read the offset value from the scale on the compass scale 7 based on the actual position of the shooting distance from the bullseye and in combination with the adjusted position of the sight block. The compass scale 7 has a circumference of 21 cm, and its scale design has been carefully optimized. Compared with the traditional method of calculating the average point of impact for correction calculation, the calibration process is greatly simplified. The operator no longer needs to perform complex calculations. By simply rotating the operation and reading the scale, the calibration of the firearm sight can be quickly and accurately completed, significantly improving the convenience and accuracy of sighting the firearm, providing a more efficient and reliable guarantee for shooting operations. The outer circle of the compass scale 7 has 21 equally spaced circumferential long scale lines and 21 equally spaced circumferential short scale lines with intervals. The scale lines are corresponding to clockwise and counterclockwise indication numbers for quickly reading when the pointer 5 rotates clockwise and counterclockwise. The scale lines are coated with luminous paint for indicating the scale when used at night. There is an operation identification of "1 circle = 21 cm" on the surface of the compass scale 7 for guiding the user to operate and use.

[0021] Working principle: First, put the bushing 9, washer 10, compass scale 7, rubber ring 11, and U-shaped block 13 on the outside of the main shaft 1 from top to bottom. Then, put the threaded ring 16 on the external thread of the main shaft 1 for installation. Finally, install the pointer 5 at the installation hole 4 through the screw 6. After such assembly, the combined groove 17 at the bottom of the main shaft 1 can be aligned with the top of the sight block for combination. Then, the compass scale 7 can be manually rotated for zero calibration. Then, rotate the torsion bar 3 to drive the main shaft 1 to rotate, and then drive the sight block to rotate. In this way, the position of the sight block can be raised or lowered. Combined with the position of the shooting distance from the bullseye, the offset value can be directly read from the scale on the compass scale 7. And the pointer 5 is made of luminous material, which is convenient for reading at night. The circumference of the compass scale 7 is 18 cm, which is more convenient and accurate than the traditional method of calculating the average point of impact for correction calculation.
