Description

Technical Field

[0001] The utility model relates to the field of aiming sights, in particular to a device for quickly detecting the sight center of an aiming sight. Background Technique

[0002] In many key fields such as military, shooting sports, hunting, and precision instrument calibration, the accuracy of the sight center of an aiming sight plays a crucial role, which directly affects the accurate shooting or positioning of the target. However, the traditional methods for detecting the sight center of an aiming sight have exposed many deficiencies in practical applications. Most of these methods rely on manual visual comparison, which is not only inefficient but also easily affected by the subjective judgment of the observer, resulting in difficult-to-guarantee accuracy. In addition, some methods use mechanical adjustment frames or simple angle measurement tools for detection. Although these tools can improve the accuracy of detection to a certain extent, they are complex to operate, require professional personnel to operate, and are also easily interfered by environmental conditions (such as light, temperature, etc.), greatly reducing the stability and reliability of the detection results.

[0003] Specifically, the method of manual visual comparison requires the observer to observe the deviation between the sight center of the aiming sight and the target point with the naked eye and make manual adjustments. This method is not only time-consuming and laborious but also has limited accuracy and is difficult to meet the requirements of high-precision shooting or positioning. Although the mechanical adjustment frame can achieve more precise angle adjustment, its structure is complex, the operation is cumbersome, and the skill requirements for the operator are relatively high. As for simple angle measurement tools, such as protractors, although they can measure angles, they cannot directly reflect the actual deviation of the sight center of the aiming sight, so their applications are also limited.

[0042] Working principle of the gear system

[0043] The transmission gear system in this device includes a first transmission gear 3, a second transmission gear 4, a third transmission gear 10, and a fourth transmission gear 11. They achieve power transmission and angle adjustment through an accurate meshing relationship. The first transmission gear 3 and the second transmission gear 4 are respectively installed in the installation groove 2 and the opening 12 of the base 1, and are rotationally connected through a rotating shaft 19 and a damping shaft 20. The damping shaft 20 provides appropriate resistance to make the gear rotate more smoothly and have a certain self-locking function to prevent accidental rotation. The third transmission gear 10 and the fourth transmission gear 11 are connected through a hinge shaft and a bracket 5, and the damping shaft 20 is also used to ensure the stability and accuracy of rotation.

[0044] Working principle of the angle measuring instrument

[0045] This device uses a dual angle measuring instrument (angle measuring instrument one 6 and angle measuring instrument two 7) to ensure the precise detection of the sight center of the sight. The angle measuring instrument one 6 is of a circular ring structure and is fixed on the base 1 to provide a reference for the entire device. The angle measuring instrument two 7 is slidably connected to the angle measuring instrument one 6 through a chute 25, allowing for fine adjustment to adapt to different sizes of sights or detection requirements. Both are provided with scale lines 21 for reading and adjusting the angle value. When the bracket 8 drives the sight and the laser emitter 22 to rotate, the angle measuring instrument one 6 can display the angle change in the horizontal direction in real time; while the angle measuring instrument two 7 measures and displays the fine adjustment amount of the angle in the vertical direction through the sliding connection between the measuring rod 15 and the measuring groove. This design of dual angle measurement greatly improves the accuracy and flexibility of detection.

[0046] Working principle of the fastening rod 9 and the bracket 8

[0047] The fastening rods 9 provided at both ends of the bracket 8 penetrate through the bracket 8 via a threaded structure to achieve stable fixation of the sight. This design allows users to adjust according to the size and shape of the sight and lock it on the bracket 8 by rotating the fastening rod 9. The end of the fastening rod 9 preferably includes a buffer rubber pad to reduce friction and damage to the sight, while improving the stability and safety of fixation. By adjusting the tightness of the fastening rod 9, users can ensure that the sight maintains a stable posture during the detection process, avoiding detection errors caused by vibration or loosening.

[0048] Principle of operation of the disc 18 and the reference rod 17

[0049] The disc 18 sleeved on the bracket 5 is located inside the first angle measuring instrument 6 and is used in conjunction with the scale line 21 of the angle measuring instrument. Reference rods 17 are provided on both the disc 18 and the measuring rod 15. These reference rods 17 are adapted to the scale line 21 of the angle measuring instrument and are used to further calibrate and verify the center position of the sight. When making an angle adjustment, users can observe the alignment of the reference rod 17 and the scale line 21 to determine whether the adjustment is in place. This design not only improves the accuracy and reliability of the detection but also provides users with intuitive visual feedback, making the operation more simple and fast.

[0050] The present utility model describes a device for quickly detecting the center of a sight, and its principle of operation mainly revolves around the following key components and their interactions:

[0051] Base 1 and the first angle measuring instrument 6:

[0052] The base 1 serves as the support platform for the entire device, and the annular structure first angle measuring instrument 6 configured thereon provides an angle reference in the horizontal direction. The mounting groove 2 at the top of the base 1 is used to mount the first drive gear 3, and the opening 12 at the front side is used to mount the second drive gear 4. The two achieve horizontal angle adjustment through a meshing relationship.

[0053] Adjustment device:

[0054] The adjustment device consists of the first, second, third, and fourth drive gears and the bracket 5 and the bracket 8. The first drive gear 3 is installed in the mounting groove 2 via a rotating shaft 19, and the second drive gear 4 is installed in the opening 12 at the front side of the base 1 and meshes with the first drive gear 3. This design allows users to drive the first drive gear 3 and the entire bracket 8 system (including the sight and the laser emitter 22) to make horizontal angle adjustments by rotating the second drive gear 4.

[0055] The bracket 8 hinged to the top of the bracket 5 is connected to the bracket 5 through the hinge edge 13 and the hinge shaft, enabling the bracket 8 to be finely adjusted in the vertical direction. The third transmission gear 10 is sleeved on the hinge shaft and meshes with the fourth transmission gear 11. By rotating the fourth transmission gear 11, the third transmission gear 10 and the bracket 8 can be adjusted in the vertical direction.

[0056] Measuring device:

[0057] The measuring device includes a laser emitter 22 and an angle measuring instrument II 7 with a semi-circular structure. The laser emitter 22 is arranged at one end of the bracket 8 for emitting a laser beam to simulate the shooting path, and the aiming scope is arranged at the other end of the bracket 8. The laser beam emitted by the laser emitter 22 passes through the sighting center of the aiming scope and is adapted to the crosshair 24 on the calibration frame 23.

[0058] The angle measuring instrument II 7 is connected to the bracket 5 through a connecting rod 16. A measuring groove is provided on its inner side and is used in cooperation with a measuring rod 15 on the measuring edge 14 on the other side of the bracket 8. The end of the measuring rod 15 is adapted to the measuring groove, enabling the user to read the fine adjustment amount of the vertical angle by observing the position of the measuring rod 15 in the measuring groove. Scale lines 21 are provided on both the angle measuring instrument I 6 and the angle measuring instrument II 7 for accurately reading and adjusting the angle value.

[0059] Calibration frame 23:

[0060] The crosshair 24 and the scale line 21 provided on the calibration frame 23 are used for further calibration and verification processes. The user can place the calibration frame 23 at the target position and adjust the vertical and horizontal angles of the aiming scope and the laser emitter 22 through the adjustment device, so that the adjustment angle of the emitted laser beam coincides with the scale line 21 on the crosshair 24 of the calibration frame 23, thereby verifying whether the sighting center of the aiming scope is accurate.

[0061] In summary, the device realizes the precise adjustment of the aiming scope in the horizontal and vertical directions through the adjustment device, reads and adjusts the angle value in real time through the measuring device, and finally verifies and calibrates through the calibration frame 23. This design makes the process of detecting the sighting center of the aiming scope faster, more accurate and more convenient.
