A correction agency. The sight is usually equipped with a height correction mechanism that adjusts the height position of the zoom unit. High-end products are equipped with a height bounce correction mechanism and a windage bounce correction mechanism used to adjust the horizontal position of the zoom unit.

Please refer to Figure 1, which shows a conventional sight 10. The conventional sight 10 includes a main body 11 and an impact correction mechanism fixed on the main body 11 . The impact correction mechanism includes an adjustment knob 20, an adjustment bolt 22, a base 24, a spring 26 and a warhead 28. The adjustment knob 20 is fixed with the adjustment bolt 22 through the screw 29, so the adjustment knob 20 and the adjustment bolt 22 form a linked relationship, and the base 24 is fixed on the body 11 of the sight 10. The adjusting bolt 22 has a side wall, and a receiving groove 221 is opened on the side wall to receive the spring 26 and the bullet 28 in sequence. One end of the bullet 28 abuts the spring 26 and the other end protrudes from the side wall of the adjusting pin 22 . The base 24 has a hollow cylindrical member 245 with screws 247 on its inner wall. When the adjustment knob 20 drives the adjustment bolt 22 to rotate, the warhead 28 moves along the lines of the screws 247, so that the adjustment bolt 22 moves relative to the base 24. Move up and down. The adjusting pin 22 has a lower end 223 , an opening is opened in the center of the base 24 , and the lower end 223 of the adjusting pin 22 passes through the opening of the base 24 . When the adjustment knob 20 drives the adjustment bolt 22 to move up and down, the lower end 223 of the adjustment bolt 22 can push against the variable magnification unit in the sight 10 and change its height position to perform impact correction.

As shown in FIG. 2 , the inner wall surface of the base 24 is also provided with a tooth portion 249 . The screw thread 247 and the tooth portion 249 are provided on the inner wall surface of the base 24 . The tooth portion 249 is a plurality of columnar structures extending in the radial direction. These columnar structures are parallel to each other and arranged in an annular manner on the inner wall surface. Threads 247 extend through these columnar structures. When the user turns the adjustment knob 20 and the adjustment knob 20 drives the adjustment bolt 22 to rotate, so that the warhead 28 moves along the inner wall of the base 24, the spring 26 pushes the warhead 28 out, so that the warhead 28 is in contact with the inner wall of the base 24. The teeth 249 are in contact to create a sense of step. The user can adjust the speed of rotating the adjustment knob 20 through this step feeling.

The impact correction accuracy of the sight is related to the rotation angle of the minimum rotation amount of the adjustment knob of the impact correction mechanism. For this paragraph-like design, the size of the bullet needs to match the size of the teeth on the inner wall of the base. In order to meet the accuracy requirements of this rotation angle, it is necessary to increase the number of teeth on the inner wall of the base. However, if there are too many teeth on the inner wall of the base, the sense of segmentation will not be obvious and it will not be able to provide a better user experience. Under the same accuracy requirements, if the size of the bullet is reduced to improve the sense of step, it will intensify the wear of the teeth and the bullet on the inner wall of the base, affecting the service life. With the current sight manufacturing process, the number of teeth on the inner wall of the base can only be increased to 100 teeth at most, and the accuracy corresponding to the rotation angle of each tooth is 360/100=3.6

The conventional sight has the following technical problems: (1) The segmented design makes it difficult to further improve the rotation angle accuracy of the adjustment knob of the ball impact correction mechanism, making it difficult to meet the accuracy requirements of ball impact correction; and (2) The warhead The contact with the teeth on the inner wall of the base can easily cause wear of the warhead and teeth.

The word "embodiment" used in the description of this application is meant to be used as an example, illustration or illustration, and is not intended to limit the application. Furthermore, in the accompanying drawings, elements with similar or identical structures and functions are represented by the same element numbers.

Please refer to Figure 3, which shows the sight 30 of the present application. The sight 30 of the present application includes a body 31 and an aiming correction mechanism 32 provided on the body 31 . In FIG. 3 , the aiming correction mechanism 32 is presented in the form of an exploded view. The sight 30 also includes an objective lens unit 33 , an eyepiece unit 34 and a zoom unit (not shown). The zoom unit is disposed within the body 31 between the objective lens unit 33 and the eyepiece unit 34 . The aiming correction mechanism 32 is used to adjust the position of the zoom unit to perform aiming correction, such as ball impact correction. For example, the aiming correction mechanism 32 is a height aiming correction mechanism, used to adjust the height position of the zoom unit; or the aiming correction mechanism 32 is a windage aiming correction mechanism, used to adjust the horizontal position of the zoom unit. The sight 30 may only be equipped with a height aiming correction mechanism to adjust the elevation angle of the zoom unit, or the sight 30 may be equipped with both a height aiming correction mechanism and a windage aiming correction mechanism to adjust the position of the zoom unit in the vertical and horizontal directions. In a feasible solution, the sight 30 is used for aiming correction, and can be configured on, but is not limited to, a shooting instrument.

FIG. 4 shows a vertical cross-sectional view of the aiming correction mechanism 32 of the sight 30 . Please refer to FIGS. 3 and 4 together. The aiming correction mechanism 32 includes an adjustment knob 42 , an adjustment bolt 44 , an adjustment ring 46 and a base 48 . The base 48 is fixed on the body 31 of the sight 30 , and the adjustment knob 42 is combined with the adjustment ring member 46 through a fastener 50 (such as a screw), so that the adjustment knob 42 and the adjustment ring member 46 form a linked relationship. That is, when the adjustment knob 42 rotates, the adjustment ring 46 will also rotate accordingly. The adjusting ring 46 is formed with a first through hole 460 , the base 48 is formed with a second through hole 480 , and the adjusting bolt 44 includes an upper side portion 441 and a lower side portion 442 . The upper side portion 441 of the adjusting pin 44 passes through the first through hole 460 of the adjusting ring member 46 to be combined with the adjusting ring member 46 , and the lower side portion 442 of the adjusting pin 44 passes through the second through hole 480 of the base 48 to be combined with the base. 48 combined. When the adjusting knob 42 rotates, the adjusting bolt 44 can only move along one axis 320 (such as moving up and down). Specifically, the upper side portion 441 of the adjustment pin 44 is screwed to the adjustment ring 46 , and the lower side portion 442 of the adjustment pin 44 is fitted to the base 48 . When the adjustment knob 42 rotates and drives the adjustment ring member 46 to rotate, the screwing effect between the adjustment pin 44 and the adjustment ring member 46 and the fitting effect between the adjustment pin 44 and the base 48 make the adjustment pin 44 only move in the direction of the axis 320 , for example, the adjusting bolt 44 moves up and down relative to the base 48. The lower side portion 442 of the adjustment bolt 44 abuts the zoom unit in the main body 31 of the sight 30. The up and down movement of the adjustment bolt 44 can change the position of the zoom unit, thereby performing aiming correction. Such a structure prevents the adjustment knob 42 from producing a sense of step when it is rotated. That is, the aiming correction mechanism 32 of the sight 30 achieves a solution without a sense of step.

In one embodiment, the adjusting ring member 46 has an annular groove 462 (see also FIG. 10 ), and the adjusting knob 42 abuts against the annular groove 462 of the adjusting ring member 46 through the fixing fastener 50 and is combined with the adjusting ring member 46 . The adjusting ring member 46 forms a linkage relationship. In one embodiment, the adjustment knob 42 is combined with the adjustment ring member 46 by at least two fixing fasteners 50 abutting against the annular groove 462 of the adjustment ring member 46 . In one embodiment, the distance between the adjustment knob 42 and the base 48 is fixed along the direction of the axis 320 , that is, the rotation of the adjustment knob 42 will not cause the adjustment knob 42 to move up and down along the direction of the axis 320 . In one embodiment, the outer surface of the upper side portion 441 of the adjusting pin 44 and the inner wall of the adjusting ring member 46 are threaded. The upper side 441 of the adjustment bolt 44 has external threads (not shown), and the inner wall of the adjustment ring 46 has internal threads (not shown). The external threads are adapted to the internal threads, thereby completing the adjustment bolt 44 and the adjustment ring. The screw connection of piece 46. In one embodiment, the cross section of the lower side portion 442 of the adjusting pin 44 is a polygon, which is adapted to the contour shape of the second through hole 480 of the base 48 , thereby completing the fitting of the adjusting pin 44 and the base 48 . Therefore, when the adjustment knob 42 drives the adjustment ring 46 to rotate, the adjustment pin 44 is restricted by the base 48 and will not rotate accordingly. Instead, it moves up and down along the axis 320 due to the engagement with the base 48 .

The aiming correction mechanism 32 of the present application is an aiming correction mechanism without any sense of step, that is, when the adjustment knob 42 is operated and rotated, there will be no sense of step. Compared with conventional sights, the aiming correction mechanism 32 of the present application has the following advantages: (1) The stepless design greatly improves the rotation angle accuracy of the adjustment knob 42 of the aiming correction mechanism 32, meeting the accuracy requirements of aiming correction. ; (2) There is no problem of tooth wear on the inner wall surface of the warhead and the base in the conventional technology, so that the sight can have a longer service life.

Please refer to Figures 5 to 8. The aiming correction mechanism 32 also includes a limiting member 58 and a positioning ring 60. The adjusting knob 42 has a through hole 422. The limiting member 58 is inserted into the through hole 422 of the adjusting knob 42. The positioning ring 60 is sleeved On the adjustment ring 46. The position of the limiting member 58 relative to the adjustment knob 42 can be adjusted. The limiting member 58 can be operated in a first position and a second position along the direction of the axis 320 . When the limiting member 58 is located in the first position, (See Figure 7). The limiter 58 is connected to the positioning ring 60 and functions to limit the rotation of the adjustment knob 42 within a predetermined angle range. When the limiter 58 is in the second position (see Figure 8), the limiter 58 is in the second position (see Figure 8). The positioning member 58 is separated from the positioning ring 60 and does not interact with the positioning ring 60 , so that the rotation range of the adjustment knob 42 is greater than the predetermined angle, further allowing the adjustment knob 42 to rotate multiple times.

When the limiting member 58 is operated in the first position (for example, the limiting member 58 is moved downward to connect with the positioning ring 60 ), the movement of the limiting member 58 is limited by the positioning ring 60 , so that the rotatability of the adjustment knob 42 is The angle is limited, and the rotation is performed within the predetermined angle range, which is beneficial to fine-tuning the aiming point. When the limiting member 58 is operated in the second position (for example, the limiting member 58 is moved upward and away from the positioning ring 60 ), the movement of the limiting member 58 will not be interfered by the positioning ring 60 , thereby adjusting the rotation range of the knob 42 Greater than the predetermined angle, the adjustment knob 42 can further be rotated multiple times, which allows for quick correction of the aiming point when it is necessary to adjust the aiming point in a wide range. This structural design is also conducive to zero setting and locking the zero point position, which will be described in detail later.

In one embodiment, the positioning ring 60 has a positioning groove 602. The positioning groove 602 is, for example, a groove formed on the top surface of the positioning ring 60. The positioning groove 602 defines the angle at which the adjustment knob 42 can rotate (ie, the predetermined angle). Range, the predetermined angle is less than or equal to 360 degrees. When the position of the limiter 58 falls in the positioning groove 602 of the positioning ring 60, the limiter 58 is connected with the positioning ring 60 and takes effect. At this time, the adjustment knob 42 can only move in the position defined by the positioning groove 602 of the positioning ring 60. Rotate within a predetermined angle range. When the position of the limiter 58 does not fall into the positioning groove 602 of the positioning ring 60, the limiter 58 is separated from the positioning ring 60 and does not interact with the positioning ring 60. At this time, the rotation of the adjustment knob 42 will not be affected by the positioning ring 60. Due to the influence of the positioning groove 602, the rotation range of the adjustment knob 42 is greater than the predetermined angle or the adjustment knob 42 can perform multiple rotations.

In one embodiment, the through hole 422 of the adjusting knob 42 penetrates the adjusting knob 42 in the longitudinal direction, that is, it penetrates the adjusting knob 42 in the axial direction of the positioning ring 60 . In one embodiment, when the adjustment knob 42 drives the adjustment ring member 46 to rotate, the adjustment knob 42 and the limiting member 58 are at a fixed distance relative to the base 48 in the direction along the axis 320 , that is, the rotation of the adjustment knob 42 does not change. This will cause the distance between the adjustment knob 42 and the limiting member 58 in the direction of the axis 320 to change. In one embodiment, the aiming correction mechanism 32 further includes a stop ring 66 , which is disposed between the limiting member 58 and the positioning ring 60 . The limiting member 58 includes an upper end 582 and a lower end 584 . The lower end 584 is disposed on the stop. In the ring 66 , when the limiting member 58 is operated in the direction of the shaft 320 (such as moving the limiting member 58 downward along the shaft 320 ) so that the lower end 584 of the limiting member 58 protrudes from the stop ring 66 , it is In the first position (see Figure 7), the limiting member 58 is connected to the positioning ring 60 and interacts with the positioning ring 60; on the contrary, when the limiting member 58 operates along the direction of the axis 320 (such as moving the limiting member 58 along the axis 320 moves upward), so that the lower end 584 of the limiting member 58 does not protrude from the stop ring 66 and is in the second position (see FIG. 8 ). The limiting member 58 is separated from the positioning ring 60 and does not interact with the positioning ring 60 .

In one embodiment, the limiting member 58 further includes a middle end portion 586 located between the upper end portion 582 and the lower end portion 584 . The through hole 422 formed in the adjustment knob 42 includes an upper section 428 and a lower section 429 . The middle end portion 586 of the limiting member 58 has a first connecting portion 580 , and the lower portion 429 of the through hole 422 has a second connecting portion 420 . The first connecting part 580 and the second connecting part 420 are correspondingly arranged and matched, so that the middle end 586 of the limiting member 58 and the lower section 429 of the through hole 422 are connected (for example, screwed to each other), wherein the limiting member 58 The first connecting portion 580 of the end portion 586 only operatively moves along the direction of the axis 320 within the range of the second connecting portion 420 of the end portion 429 under the through hole 422, so when the limiting member 58 operates along the direction of the axis 320 When moving, the middle end 586 of the limiting member 58 remains within the range of the lower section 429 of the through hole 422 without escaping from the through hole 422 . In one embodiment, the outer diameter of the middle end 586 of the limiting member 58 is larger than the outer diameters of the upper end 582 and the lower end 584 and the inner diameter of the stop ring 66 , so the movement of the middle end 586 of the limiting member 58 cannot be Will exceed stop ring 66. The first connecting portion 580 of the middle end portion 586 of the limiting member 58 is a first thread segment (not shown), and the second connecting portion 420 of the lower portion 429 of the through hole 422 is a second thread segment (not shown). , the first thread segment is adapted to the second thread segment, so that the first thread segment operatively moves in the direction of the axis 320 within the range of the second thread segment, so when the stopper 58 moves along the axis 320 When operated in this direction, the limiting member 58 is maintained between the lower section 429 of the through hole 422 and the stop ring 66 . During assembly, the limiting member 58 is installed from below the through hole 422 of the adjusting knob 42 so that the first threaded section on the first connecting portion 580 of the limiting member 58 is connected with the second connecting portion 420 of the through hole 422 . The threaded sections are combined, and then the stop ring 66 is inserted into the lower end 429 of the through hole 422. The stop ring 66 can be fixed on the adjustment knob 42 (through screwing or fitting), thereby completing the stopper 58 and the stop ring 66 and adjustment. Assembly of Knob 42.

The aiming correction mechanism 32 also includes a magnetic element 52 , an electronic board 54 and a magnetic sensor 56 provided on the electronic board 54 . The magnetic element 52 (eg, permanent magnet) is disposed on the inner side (eg, the inner top surface) of the adjustment knob 42 , and the electronic board 54 is disposed on the upper side 441 of the adjustment bolt 44 , such as the top surface of the upper side 441 . As mentioned above, when the adjustment knob 42 is rotated, the adjustment bolt 44 will move up and down. The movement of the adjustment pin 44 will cause the relative position of the magnetic sensor 56 (such as a rotary Hall-effect sensor) on the electronic board 54 to change with the magnetic element 52, so that the magnetic element 52 sensed by the magnetic sensor 56 The magnetic field changes. When the adjusting knob 42 rotates, the magnetic sensor 56 senses different magnetic fields, and the angle and number of turns of the adjusting knob 42 can be obtained after electronic calculation. The magnetic sensor 56 can sense the rotation angle with an accuracy of up to 0.01 degrees, which is much higher than the 3.6-degree resolution of the conventional sight 30. This information can be applied to the calculation of ballistic compensation, for example, and is finally presented on the sight through the display. 30 on. Therefore, the user obtains feedback on the operation of the adjustment knob 42 through the rotation angle and number of turns obtained by the magnetic induction technology, making the sight 30 more technological.

In one embodiment, the magnetic element 52 is disk-shaped, fixed on the inner top surface of the adjustment knob 42, and moves in conjunction with the adjustment knob 42. Therefore, the magnetic field of the magnetic element 52 does not substantially change when the adjustment knob 42 rotates. In one embodiment, the magnetic sensor 56 is disposed on the electronic board 54 , and the electronic board 54 is disposed on the top surface of the upper side 441 of the adjusting bolt 44 . In one embodiment, the position of the magnetic sensor 56 on the electronic board 54 is offset from the rotation axis of the adjusting pin 44; in another embodiment, the position of the magnetic sensor 56 on the electronic board 54 is located on the rotation axis of the adjusting pin 44. On the axis, that is, they are arranged at the central position. It is not limited to being arranged at the central position and can also be arranged eccentrically. In addition, the number of the magnetic sensors 56 is not limited.

The aiming correction mechanism 32 also includes a first collar 62 and a second collar 64 . The adjusting ring 46 has an annular flange 465 , the positioning ring 60 has a positioning flange 605 , the positioning ring 60 abuts against the annular flange 465 of the adjusting ring 46 , and the first collar 62 abuts against the positioning flange 605 of the positioning ring 60 . The base 48 receives the annular flange 465 of the adjustment ring 46 , and the second collar 64 is disposed between the base 48 and the body 31 , and between the base 48 and the first collar 62 . This interlocking structure can improve the stability of the aiming correction mechanism 32, especially the stability of the adjustment ring member 46. It can be assembled in the following order: base 48, second collar 64, adjustment ring 46, positioning ring 60 and first collar 62.

Referring to FIGS. 3 , 4 and 9 , three fasteners may be used to combine the adjustment knob 42 and the adjustment ring 46 . These fasteners include, for example, two fixing fasteners 50 and a limiting fastener 68 . The two fixed fasteners 50 are provided corresponding to the fixed fastener lock holes 426 on the adjusting knob 42, and are used to fix the adjusting knob 42 and the adjusting ring member 46 together, so that the adjusting knob 42 and the adjusting ring member 46 form a linked relationship. The two fixing fasteners 50 can form an included angle and resist the annular groove 462 of the adjusting ring member 46 (see FIG. 10 ), applying forces in different directions to the adjusting ring member 46 to fix it to the adjusting knob 42 . In addition, the limiting fastener 68 is provided corresponding to the limiting fastener lock hole 427 on the adjusting knob 42 to limit the adjusting knob 42 so that the adjusting knob 42 keeps rotating on the adjusting ring 46. Specifically, the limiting fastener 68 Extends into the annular groove 462 of the adjusting ring member 46 but cannot abut against the annular groove 462, that is, there is always a gap with the wall of the annular groove 462. Therefore, when the two fixed fasteners 50 are loosened, the rotation of the adjusting knob 42 cannot be achieved. The adjusting ring member 46 will be driven to rotate along the annular groove 462 of the adjusting ring member 46 by the restricting fastener 68 .

The following describes the operation of zero setting and locking the zero point position. When the sight 30 is combined with the shooting instrument for zeroing and shooting, the zeroing point position can be found through the following operations: Initially, the adjustment knob 42 and the adjustment ring 46 are fixed together through (two) fixing fasteners 50, that is, the fasteners It is in the locked state, and then the limiting member 58 is retreated to a position where it is not connected to the positioning ring 60. At this time, the adjusting knob 42 can be rotated multiple times to find the zero point position.
