Description

Technical Field

[0001] The invention belongs to the technical field of shooting sports, and in particular relates to a rail-type MOA adjustment system. Background Art

[0002] The aiming point in shooting sports (hunting or sniping) is adjusted using the minute of angle (MOA). Whether it is the original mechanical three-point straight line or the ballistic adjustment of various scopes later, they all use this MOA principle. MOA adjustment adjusts the aiming point up and down and left and right separately.

[0003] There are three main forms of MOA adjustment systems:

[0004] 1. Split type, the vertical adjustment and the left and right adjustment are not integrated into a whole, the left and right adjustment axis and the vertical adjustment axis are not in the same plane, including the three points in a straight line and the front and rear sights;

[0005] 2. Integral type, the vertical adjustment and the left-right adjustment are integrated into a whole. The left-right adjustment axis and the vertical adjustment axis are not in the same plane. There is a certain distance between the two. A return spring is used to reset, eliminate the gap and balance the left and right. This structure can be used with different scopes as a MOA adjustment platform, including red and green dot and many optical scopes.

[0006] 3. Daylight sight adjustment system, up and down adjustment and left and right adjustment are integrated into a whole, and the left and right adjustment axis and up and down adjustment axis are in the same plane;

[0007] At present, all the integrated adjustment systems on the market use reset springs to reset the up and down adjustments and maintain the balance without pendulum when adjusting left and right. The instability of the spring affects the adjustment accuracy. In particular, the impact vibration generated by shooting will cause fluctuations in the adjustment position, which is very unfavorable for continuous shooting and aiming. Since the left and right adjustment axes and the up and down adjustment axes of the adjustment system are not in the same plane, the matching accuracy requirements of parts in multiple positions are caused. If the matching accuracy of any one position is not well controlled, the adjustment accuracy will be affected. At the same time, installation and debugging are inconvenient. For this reason, a rail-type MOA adjustment system is designed. Summary of the Invention

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0032] See also Figure 1-2 As shown, the present invention is a guide rail type MOA adjustment system, comprising a main body 1 and a base 2, wherein the base 2 is located at the bottom end of the main body 1. One end of the main body 1 and the base 2 are fixed by a ball screw 15. The main body 1 and the base 2 are rotated up and down and left and right around the center of the ball screw 15 to change the relative angle between the two, thereby achieving MOA adjustment in the up and down and left and right directions.

[0033] There are two threaded holes on the other end of the main body 1, one of which is perpendicular to the ground and the other is parallel to the ground.

[0034] A first adjusting screw 4 is provided inside one of the threaded holes, a gear ring 7 is provided inside one of the threaded holes and outside the first adjusting screw 4, and the gear ring 7 is fixed to the main body 1, so that the first adjusting screw 4 can only rotate in the main body 1, and a first adjusting handwheel 3 is rotatably connected to the top of the main body 1, and the first adjusting screw 4 is connected to the first adjusting handwheel 3 through a first cylindrical pin 22, so that the first adjusting handwheel 3 can be rotated to drive the first adjusting screw 4 to rotate;

[0035] A tapered pin 17 and a tapered pin spring 18 are provided inside the first adjusting screw 4. One end of the tapered pin 17 is fixed to the tapered pin spring 18, and one end of the tapered pin spring 18 is fixed to the first adjusting screw 4, so that the tapered pin 17 can slide inside the first adjusting screw 4 and move and reset due to the elasticity of the tapered pin spring 18. When the first adjusting screw 4 is rotated, the tapered pin 17 inside the first adjusting screw 4, pushed by the corresponding tapered pin spring 18, will make a clicking sound when passing through each tooth punched in the corresponding hole of the gear ring 7, thereby performing indexing and reminding the operator to count the up and down adjustments;

[0036] Two adjusting nuts 8 are provided inside the main body 1;

[0037] One of the adjusting nuts 8 is slidably connected inside the main body 1 and at the bottom of the first adjusting screw 4, so that one of the adjusting nuts 8 can only move up and down and slide inside the main body 1, and cannot rotate. The first adjusting screw 4 is threadedly connected to one of the adjusting nuts 8, so that when the first adjusting screw 4 is rotated, one of the adjusting nuts 8 is pushed to move up and down;

[0038] A second adjusting screw 6 is provided inside the other threaded hole, and a gear ring 7 is provided inside the other threaded hole and outside the second adjusting screw 6. The gear ring 7 is fixed to the main body 1 so as to allow the second adjusting screw 6 to rotate only in the main body 1. A second adjusting handwheel 5 is rotatably connected to one end of the main body 1, and the second adjusting screw 6 is connected to the second adjusting handwheel 5 through a first cylindrical pin 22. Rotating the second adjusting handwheel 5 drives the second adjusting screw 6 to rotate.

[0039] The second adjusting screw 6 is further provided with a tapered pin 17 and a tapered pin spring 18. One end of the tapered pin 17 is fixed with the tapered pin spring 18, and one end of the tapered pin spring 18 is fixed to the second adjusting screw 6, so that the tapered pin 17 can slide inside the second adjusting screw 6 and move and reset due to the elasticity of the tapered pin spring 18. When the second adjusting screw 6 is rotated, the tapered pin 17 inside the second adjusting screw 6, pushed by the corresponding tapered pin spring 18, makes a clicking sound when passing through each tooth punched in the hole of the corresponding gear ring 7, thereby performing indexing and reminding the operator to count the up and down adjustments.

[0040] Another adjusting nut 8 is slidably connected to the other end of the second adjusting screw 6 inside the main body 1, so that the other adjusting nut 8 can only move up and down and slide inside the main body 1, and cannot rotate. The second adjusting screw 6 is threadedly connected to the other adjusting nut 8, so that when the second adjusting screw 6 is rotated, the other adjusting nut 8 is pushed to move left and right;

[0041] It also includes a slider 9, and the slider 9 has two mutually perpendicular T-shaped guide grooves, one of which is perpendicular to the ground, and the other is parallel to the ground. The interior of one of the T-shaped guide grooves is slidably connected to one of the adjusting nuts 8, so that one of the adjusting nuts 8 can only slide up and down in the interior of one of the T-shaped guide grooves, but cannot rotate, and the interior of the other T-shaped guide groove is slidably connected to the other adjusting nut 8, so that the other adjusting nut 8 can only slide left and right in the interior of the other T-shaped guide groove, but cannot rotate, thereby realizing left and right adjustment and upward and downward adjustment. The lower adjustment can be performed separately, and the slider 9 slides up and down and left and right inside the main body 1 through one of the adjusting nuts 8 and the other adjusting nut 8; when the first adjusting screw 4 is rotated for adjustment, one of the adjusting nuts 8 will be pushed to drive the slider 9 to move up and down along the other adjusting nut 8 in one of the T-shaped guide grooves of the slider 9; when the second adjusting screw 6 is rotated for adjustment, the other adjusting nut 8 will be pushed to drive the slider 9 to move left and right along the other T-shaped guide groove of the slider 9; since it is a pure thread adjustment, the force is uniform during the entire adjustment process, which ensures smooth adjustment.

[0042] A cylindrical surface is fixed to the bottom of the slider 9, and a fixed block 10 is fixed inside the top of the base 2. The slider 9 is connected to the fixed block 10 through a second cylindrical pin 23. A first waist-shaped groove is provided inside the fixed block 10 for allowing the cylindrical surface at the bottom of the slider 9 to slide and rotate in the first waist-shaped groove of the fixed block 10; when the first adjusting hand wheel 3 is rotated for up and down adjustment, the second cylindrical pin 23 on the slider 9 will move in the first waist-shaped groove of the fixed block 10, so that the fixed block 10 pushes the base 2 to rotate up and down between the main body 1 with the center of the ball screw 15 as the center when moving, thereby realizing MOA adjustment in the up and down directions; when the second adjusting hand wheel 5 is rotated for left and right adjustment, the second cylindrical pin 23 on the slider 9 will swing in the first waist-shaped groove of the fixed block 10, and at the same time, the fixed block 10 pushes the base 2 to rotate left and right between the main body 1 with the center of the ball screw 15 as the center, thereby realizing MOA adjustment in the left and right directions.

[0043] A second waist-shaped groove is provided at the bottom end of the other T-shaped guide groove on the slider 9. A second spring 20 is provided at the bottom of the first adjusting screw 4 and inside the second waist-shaped groove to eliminate the gap between the first adjusting screw 4 and one of the adjusting nuts 8 and between the other adjusting nut 8 and the other T-shaped guide groove of the slider 9.

[0044] A square groove is formed at the other end of one of the T-shaped guide grooves on the slider 9, and a spring mounting hole is formed inside the main body 1 at a position corresponding to the square groove. A first spring 19 and a spring nail 16 are provided between the square groove and the spring mounting hole, and the first spring 19 is sleeved on the outside of one end of the spring nail 16. The spring nail 16 is fixed to the square groove, and the first spring 19 is fixed to the spring mounting hole, so that the spring nail 16 can slide between the square groove and the spring mounting hole and its position can be adjusted by the first spring 19; it is used to eliminate the gap between the second adjusting screw 6 and the other adjusting nut 8 and between one of the adjusting nuts 8 and one of the T-shaped guide grooves of the slider 9;

[0045] The bottom end of the main body 1 is fixedly connected to the limit plate 11 by a screw 24, and the model of the screw 24 is M2, which ensures that the slider 9 is limited by the limit plate 11 when adjusting downward;

[0046] In order to ensure that the adjusted slider 9 is fixed in position, the guide rail type MOA adjustment system has a screw sleeve 13 fixed inside one side of the main body 1, and the internal thread of the screw sleeve 13 is connected to a locking screw 14. A locking handwheel 12 is rotatably connected to one side of the main body 1, and the locking handwheel 12 is connected to the locking screw 14 through a third cylindrical pin 21. By rotating the locking handwheel 12, the locking screw 14 can be driven to move and thus lock the position of the slider 9;

[0047] Therefore, the connection between the main body 1 and the base 2 of this system is a hard connection without the use of springs, which effectively eliminates the instability of the accuracy in the up and down directions caused by the use of springs. At the same time, the side swing caused by the use of springs will not occur during left and right adjustment, ensuring the accuracy of continuous shooting and aiming.
